• Motherboard Issue - 3 Beep Bios (memory error) despite new RAM

  - by Glenn

  I have an Intel dG43RK motherboard, bought new and sealed, and have tried two different brands and speeds of RAM with a 3-beep BIOS indicating a memory error, which also occurs without RAM installed (as it should). The memory tried is; 1x4GB 1333 Kingston HyperX DDR3 RAM (New and Sealed) 2x4GB Team Elite 1066 DDR3 RAM (New and Sealed) I have tried multiple configurations and seating layouts and still no luck. I also have a GT520 graphics card on board as I dislike in-built graphics in most cases and had it at hand (also new and sealed). The only used parts are the CPU, which worked in my previous tower and was directly taken from the PC into the new set-up and the CPU Fan which will be replaced with a new fan in the foreseeable future once this is resolved. I've run out of ideas myself and any help is appreciated.

• Trick XP into having more RAM?

  - by Industrial

  Hi everyone, Are there any way known to trick an computer with XP to appear to have more RAM? I need to install a specific program (which fits in my system requirements), which is bundled with a number of other programs on an DVD. Unfortunately, the other programs besides the one that I need demand twice the amount of RAM that's available on my computer and the installation is closed due to this. Can I trick my XP computer into have more RAM temporarily to bypass the block in the install executable? Thanks

• Frequency of RAM

  - by Vignesh Palani

  I have a very old system hp compaq dx2080. It had 1gb of RAM. I recently bought a EVM DDR2 1 GB PC RAM which had a clock rate of 667Mhz. I have dual booting windows 7 and 8. When I installed it, windows 7 was still using the older 1gb. It showed as 2 gb available and 1gb usable in system properties. I searched around and found that I can change it to max in the msconfig. I did so. I set it 2048. Still, it was using only 1gb. When, I switched to 8, it was using the 2gb. Now, for my question: My system only supported 553Mhz and 667Mhz RAM. In the BIOS, I saw that the new RAM was showing as 800Mhz. Rechecked using speccy and cpu-z. It showed different values between the two. The RAM is labeled as 667Mhz over it. No mistake in that. But, am I missing something? Please help. And, can I continue using it? My point again. There are only two slots.

• PC3200 RAM in Older Computer?

  - by skaz

  Hello all, I am inheriting a Dell Dimension 8200, but it needs RAM to get up and running. I have PC3200 sticks lying around, but I am not sure how to go about figuring out if the RAM is compatible, as RAM has always confused me. Here is the Dell Dimension 8200 Tech Specs: http://support.dell.com/support/edocs/systems/dim8200/specs.htm For RAM, it says: Memory type PC800 (non-ECC) I don't know if that is just the kind that comes with it, and I can put in PC3200 (I think, if it worked, this would run at the lower rating? Is that true?), or if that means only PC800 is compatible. Any help would be appreciated.

• RAM upgrade, what options are suitable?

  - by user55150

  I have a Dell GX520 optiplex model (mini tower), and I want to upgrade its RAM. I currently have 1GB RAM and I want to upgrade to 2GB. All I know about RAM is its capacity, and I've heard about speeds lately like 400mhz, 533mhz, 800mhz, 1333mhz. I want to know what are the differences among them and can my PC support all those types of speeds or not? And what is the most suitable one for my Dell PC, to avoid any problems or limitations.

• vSphere education - What are the downsides of configuring virtual machines with *too* much RAM?

  - by ewwhite

  VMware memory management seems to be a tricky balancing act. With cluster RAM, Resource Pools, VMware's management techniques (TPS, ballooning, host swapping), in-guest RAM utilization, swapping, reservations, shares and limits, there are a lot of variables. I'm in a situation where clients are using dedicated vSphere cluster resources. However, they are configuring the virtual machines as though they were on physical hardware. In turn, this means a standard VM build may have 4 vCPUs and 16GB or more of RAM. I come from the school of starting small (1 vCPU, minimal RAM), checking real-world use and adjusting up as necessary. Some examples from a "problem" cluster. Resource pool summary - Looks almost 4:1 overcommitted. Note the high amount of ballooned RAM. Resource allocation - The Worst Case Allocation column shows that these VMs would have access to less than 50% of their configured RAM under constrained conditions. The real-time memory utilization graph of the top VM in the listing above. 4 vCPU and 64GB RAM allocated. It averages under 9GB use. Summary of the same VM What are the downsides of overcommitting and overconfiguring resources (specifically RAM) in vSphere environments? Assuming that the VMs can run in less RAM, is it fair to say that there's overhead to configuring virtual machines with more RAM than they need? What is the counter-argument to: "if a VM has 16GB of RAM allocated, but only uses 4GB, what's the problem??"? E.g. do customers need to be educated? What specific metric should be used to meter RAM usage. Tracking the peaks of "Active" versus time?

• Screen going black, further investigation reveals healthy ram and hard disk, and several kernel oops logs

  - by Virulan

  Six days ago, I went to go take a shower, and I suspended Ubuntu as usual, to save battery life. I came back, and the screen was black. REISUB and general fiddling around did nothing. Restarted, and still had nothing on the screen. Since then, this has happened several times, and the only fix is to 1) force shut laptop, 2) take out battery, 3) hold power button, 4) put battery back in, 5) boot. I have investigated further into the matter, doing a ram test and a hard disk check. Both turned out fine, but then my attention turned towards the error messages I was receiving upon bootup, the whole "System program problem detected" dealio. I did some digging and found four kernel oops logs in my /var/crash. What I can understand of them points to two things, 1) they are connected to my suspending problems, since there are four them (I have had four suspending crashes), and they both confirm that there was a issue with waking up from suspend, and 2) the crashes might have to do with Python (possibly could be jumping to conclusions), since mentions of Python are peppered throughout the logs. At this point, I am unsure of how to continue, and I have come here for help. Is there any way I can fix this? Should I start by uploading the logs here?

• Computer always freezing after random periods of time. No errors listed.

  - by Wesley

  Hi, all. Here are my specs beforehand: AMD Athlon XP 2400+ @ 2.00 GHz, 160GB IDE HDD, 128MB GeForce 6200 AGP, 2 x 512MB PC3200 DDR RAM, CoolMax 350W PSU, 1 x CD-RW Drive, 1 x DVD-ROM Drive, FIC AM37 Mobo, Windows XP Pro SP3 My desktop freezes after random periods of time but there are no errors listed in the Event Viewer after a forced shutdown and restart. A couple months ago, I found that when it froze, the floppy was being accessed at the same time. So, I disconnected the floppy (since I never used it anyways) from the power supply and motherboard. Everything was working fine and the computer never froze. This past Christmas break, I left for a Conference and when I got home, the computer kept freezing again. So, this time, I just disconnected the DVD reader (from mobo and power) and started it up. Still, it froze almost right away. Then I found some older sticks of RAM (2 x 256MB PC2100 DDR) and swapped them in. Everything worked fine again after that. I even swapped the 2 x 512MB PC3200 DDR RAM back in and everything worked okay. Then it started freezing again, and I tried all possible RAM combos, still freezing within 5-10 minutes of startup. One thing I've realized is that the floppy drive is still listed in My Computer and I uninstalled it from my Device Manager already. There were no software errors, and I uninstalled the most recent software, with no effect. Still, I have no idea what is wrong because everything ran fine before that. Any suggestions? EDIT: Still have yet to buy some blank CD media to use Memtest86+. However, would a lack of virtual memory cause the computer to freeze? EDIT2: So after a long time, I ran Memtest86+ and all is well. Turns out though, after removing my original DVD reader and replacing it with a DVD-ROM drive, there is no freezing whatsoever! Thanks for all your suggestions!

• Determining how all memory is used in Windows Server 2008

  - by Mojah

  Hi, I have a Windows Server 2008 system, which has 12GB of RAM. If I list all processes in the Task Manager, and SUM() the memory of each process (Working Set, Memory (Private Working Set), Commit Size, ...), I never reach more than 4-5GB that should be "in use". However, task manager reports this server has 11GB in use via the "Performance" tab. I'm failing in determining where all that used RAM is going. It doesn't seem to be system cache, but I can not be sure. It might be a memory leak in one of the appliances, but I'm struggling to find out which one. The server's memory keeps filing up, and eventually forces us to reboot the device to clear it. I've been reading up on how RAM assignments work on Windows Server: RAM, Virtual Memory, Pagefile and all that stuff: http://support.microsoft.com/kb/2267427 What's the best way to measure? http://www.zdnet.com/blog/bott/windows-7-memory-usage-whats-the-best-way-to-measure/1786 Configure the file system cache in Windows: http://smallvoid.com/article/winnt-system-cache.html But I fear I'm stuck without ideas at the moment.

• Should you disable page file with SSD?

  - by Pyrolistical

  I've been reading http://serverfault.com/questions/23621/any-benefit-or-detriment-from-removing-a-pagefile-on-an-8gb-ram-machine, and it has a lot of great information. But assuming you have more than enough ram, I think page file should be disabled on SSD to extend the life time. I know you would lose the core dump on crash, but not many people need that information. From my understand without a page file as you reach the limit of your ram that might trigger thrashing on disk. But for SSDs there is no concept of thrashing, reads are fast. What do you guys think?

• Slow Resume After suspend having chrome running with many tabs

  - by tUrGoNn

  I usually use chrome and Firefox for browsing. I also open many tabs (around 40 in both some times). The problem I have occurs when I resume the PC after having suspended it: It takes from 2 to 5 minutes sometimes to just get back normally. Does this have to do with memory usage not properly resuming? Is it a bug in Chrome/Firefox or Ubuntu itself? Note that I just upgraded from 10.10 to 11.10 and I was having the problem on both releases, which makes me guess that it has to do with Ubuntu not resuming well if some memory-heavy apps were running before the suspend occured.

• mongodb eating 48G in 1min

  - by ledy

  In mongodb i work with this collection: Size 55.93g Data Size 39.82g Storage Size 41.08g Extents 53 Indexes 4 Index Size 9.64g It takes few seconds of mongdb being up with this single collection and all 48GB RAM on the dedicated server are gone. That's worse because there is also a mysqld+nginx/fcgi on this machine which should be allowed to use at least 24GB together. I.e. remaining 24GB, enough for the mongod! However, it does not share in a fair way. Everybody says that the memory for mongod is managed by OS and releases unneccessary space for other processes if they demand RAM. On my machine it is not releasing RAM. What's wrong? free total used free shared buffers cached` Mem: 49559136 49403908 155228 0 57284 47247564 -/+ buffers/cache: 2099060 47460076 Swap: 8008392 164 8008228

• MongoDB index/RAM relationship

  - by Tegan Clark

  I'm about to adopt MongoDB for a new project and I've chosen it for flexibility, not scalability. From the documentation and web posts I keep reading that all indexes are in RAM. This just isn't making sense to me as my indexes will easily be larger than the amount of available RAM. Can anyone share some insight on the index/RAM relationship and what happens when both an individual index and all of my indexes exceed the size of available RAM?

• Can I use the unused 1G of 4G on a 32bit machine as a ramdisk?

  - by askvictor

  I have a machine with 4G of RAM, but running 32bit windows 7, so can only see 3G. I have read somwhere recently that that unused 1G can be used as a RamDisk. Is this true? What sort of program allows that, and how does it address that gig of RAM?

• Is special memory required for a MacBook Pro ?

  - by user38900

  I have a MacBook Pro (MacBookPro5,2 / 2.8 GHz) with 4 GB of ram (2x2GB). I'm looking to upgrade to 8GB. The memory in it now is DDR3 PC3-8500 1067. Checking out prices for 4 GB sticks of PC3-8500 there is about $100 difference for "apple certified" ram. Will any DDR3 PC3-8500 module work or is there really a difference?

• Apache heavy load VIRT vs RES memory

  - by pako

  I have a Debian 5 server, which gets a lot of traffic. Right now the server has 4 GB of RAM and no swap memory. I see in top that Apache processes consume roughly 180 MB virtual memory (VIRT) each, and 16 MB of real RAM (RES). So how many Apache threads can I have running at the same time? About 4 GB / 180 MB = 22 or 4 GB / 16 MB = 256?

• Half of installed RAM is hardware reserved

  - by user968270

  After a rather arduous and convoluted series of problems that left me without a desktop for ~80 days, I've finally got the thing up and running, having replaced the power supply, motherboard, graphics card and CPU. Now, however, I'm experiencing the 'hardware reserved RAM' issue. Perhaps this is the exhaustion talking, but looking at the question that tends to get pointed to when this kind of topic gets locked as a duplicate hasn't helped. I have 16 GB of RAM installed in an MSi 970A-G46, which is spec'd for up to 32 GB of RAM. The BIOS recognizes that I have 16 GB installed, and the resource monitor also shows the whole 16 GB, only it shows 8 GB as hardware reserved. I've seen suggestions that it's an OS issue, but the particular installation of Windows 7 (64-bit) which I'm running on my boot drive is the same as the one that could actually access the 16 GB in my previous motherboard (MSi 870A-G54). I've updated my BIOS using the MSi Live Update tool and restarted the machine with no effect, and I cannot seem to locate any 'Memory Remapping' option as I've seen mentioned. I've physically swapped the RAM between the slots to no effect. I've unchecked the Maximum Memory box in the msconfig Boot tab's advanced options, also to no effect. These are my system's basic specifications OS: Windows 7 Home Premium (64-Bit) Motherboard: MSi 970A-G46 CPU: AMD FX-8150 Graphics Card: XFX Radeon HD 6870 Boot Drive: OCZ Agility 3 Storage Drive: Samsung Spinpoint F3 ST1000DM005/HD103SJ 1TB PSU: Thermaltake TR-2 TR600 600W ATX12V v2.3

• Installed Memory (RAM): 8GB (4GB Useable)

  - by Mike Bannister

  I have 4X 2GB RAM sticks installed, Windows 7 Ultimate x64 shows "Installed Memory (RAM): 8GB (4GB Useable)" in the system information. The motherboard says it supports up to 16GB of memory. I had Windows XP x64 and I'm pretty sure it was able to use all 8Gigs of memory. I've just formatted and am not burning through 4GB for sure. *The BIOS only show 4096MB while booting. I was only able to find one option relating to memory mapping and it took it from 4Gigs to 3 and change. CPU-Z shows all 4 sticks as 2048MB I went in to msconfig and checked the limits, they are not set. I tried resetting the CPU and RAM sticks 3 times, the CPU has no pins to be bent (flat contacts, I5) I rearranged all the RAM. I have separate video memory from the system memory. I have a 64 bit OS (I am 100% certain) Hardware: Memory: Four Corsair XMS3 TW3X4G1333C9AG Motherboard: Asus P7P55D Pro CPU: Intel Core i5-760 BX80605I5760 Graphics: Two ZOTAC ZT-50401-10L GeForce GTX 550 Ti If anyone has new ideas or knows the exact setting in the bios, it would be greatly appreciated.

• Processor upgrade on a laptop vs. Ram upgrade. Also does ram always matter?

  - by Evan

  I have a Dell Inspiron 14r (N4110) with an Intel Core i3 and 4gb of ram. It runs very smoothly, however gaming on this laptop is very limited. This is mostly because of integrated graphics but i have seen a computer with a Core i5, and very similar specs otherwise, run games that the N4110 cannot. This other computer has integrated graphics and 6gb of ram. I am wondering whether upgrading ram or upgrading the processor make the most difference in performance. Which setup would get better performance, an i5 with 4gb of ram or an i3 with 8 gb of ram? (Both with integrated graphics) Also, is there a certain point at which you have too much ram for the computer to ever possibly use? For instance is there really any difference in performance between 8 gb and 16 gb of ram?

• spoolsv.exe consumes all CPU and RAM resources

  - by pcampbell

  Consider a Windows 7 x64 installation with 2 printers installed. The system has 8GB installed RAM. One printer is a Brother laser MFC-8220 Printer via TCP/IP, and the other is a CutePDF printer. Problem: the spoolsv.exe regularly eats obscene amount of memory and CPU when the machine is idle. Usually the device is powered off. Turning it on has no effect on the RAM or CPU usage. The first consideration was that perhaps a print job has previously been sent to the Brother, but the queues are empty, and no jobs are waiting. These screenshots do not show, but regularly the spoolsv service will consume all 8GB and climb to use 95-100% of the CPU. The two printers - a Brother and the CutePDF printer both have 0 documents in their respective queues. Question: what measures can I take to ensure the spoolsv.exe doesn't consume inappropriate amounts of CPU and RAM?

• Recommended RAM and disc space for Oracle 11g on Windows

  - by Álvaro G. Vicario

  I need to provide the recommended amount of RAM and disc space (divided in two partitions) so the customer can create an appropriate virtual machine to run Oracle. All I could find in the documentation was a brief listing with minimum RAM and typical/advanced install types. The virtual machine will run latest Oracle Standard Edition One (11g release 2 so far) under Windows Server 2008 x64 and will host a reasonably low traffic web application. How much RAM and disc must I ask for in order to be safe? (Feel free to ask for further details if I've omitted something relevant.) Update: Rough estimations: Database size: 10 MB after installation Growth rate: +3MB per day on average Size of database 'active' data: (not sure of what this means, there's not actual archive so I guess all data is current) Amount of data written per second in peak hours: a few KB Number of client sessions: 3 or 4 at most Frequency and response size of most heavy requests: some reports make heavy table JOINS that need up to 20 seconds to complete but they won't return more than a few thousand rows with plain text. The app also handles BLOBs (typical size from 50KB to 200KB)
