• NVIDIA same chipset, but different implementations - what is the difference?

  - by Horst Walter

  I have planned to buy a graphics card. When searching for a particular chipset (e.g. GTX 460) I find cards of different vendors (i.e. Gigabyte, Palit, PNY, ...). I can figure out differences in frequency, memory, and equipment. When I read test reports, usually a particular NVIDIA card is compared with its ATI/AMD "counterpart" - have not really found a comparison of all vendors for a particular NVIDIA chipset. So in order to make a decision: a) Are the drivers all the same for all the cards of a particular chipset (and provided by NVIDIA or the vendor?) b) How to figure out which card actually to buy. OK, I choose chipset, and memory, and check the card has the required ports, but then ....

• How do I enable greedy MigrationHeuristic in Karmic?

  - by Matthew

  My laptop performs very poorly for 2d graphics. For example, Docky's zoom effect and compiz effects are very choppy. In Jaunty, I was able to fix this by adding the following line under the "Device" section in my xorg.conf: Option "MigrationHeuristic" "greedy" In Karmic, there is no xorg.conf by default, so I copied my old one (from Jaunty). However, everything is still slow. Here is my xorg.conf: Section "Device" Identifier "Configured Video Device" Option "MigrationHeuristic" "greedy" EndSection Section "Monitor" Identifier "Configured Monitor" EndSection Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" Device "Configured Video Device" EndSection From googling about, it sounds like "MigrationHeuristic" is only an option for the "EXA" mode, while Karmic has switched the intel driver to "UXA". So I tried adding this line under the "Device" section: Option "AccelMethod" "exa" But this didn't help.

• Recommended CPU upgrade for Dell Vostro 220 with E7300 processor?

  - by Justin Grant

  I've got a Dell Vostro 220 with an E7300 processor (Intel Core 2 Duo @ 2.66Mhz, LGA775 socket) and I'm thinking about upgrading my processor so I can run Windows Server 2008 R2 with Hyper-V, which requires Hardware Virtualization support in the processor. Yes, I know this is underpowered for a server, I'm actually using it as a desktop machine but I'd like to use Hyper-V instead of Virtual Server (which I'm using now for running VMs). I'd like to keep the same motherboard and ideally the same CPU fan and RAM too. Any suggestions for a good, relatively cheap (under $200) processor upgrade?

• Post Error, Fixed/Removable Media Error

  - by Dan

  Hi, I really do not know what I am missing here. I ordered parts for a new server. The board is an Intel s3420GP. From the diagnostic LEDs I get the error message: 0xB1h which corresponds to "Fixed Media: Disabling fixed media" and 0xB8h which corresponds to "Removable Media: Resetting removable media device." I can not for the life of me figure out what it is talking about. I have two identical motherboards and both gave the error message. I don't have a second CPU yet, so I can't test that. There are no beeps or anything. It seems the server resets every 10 seconds or so (the speaker does work, I put the RAM in the wrong slots on purpose to test this out, and the correct error POST code came up) Please help me, I'm not sure where else to turn or to ask

• Dual Core or Quad Core CPU for NetBeans/Eclipse development?

  - by cdb

  I am going to buy a new desktop CPU. I am a programmer who mainly uses NetBeans IDE for Java web application development, with GlassFish application server. I went through the discussion regarding Dual Core or Quad Core. My doubt is that software like IDEs (NetBeans, Eclipse, etc., with a server running) may not be written with multiple cores in mind? I am not a game addict... So what is best for me, and which company should I choose, AMD/Intel?

• Flash player, HD videos and games are choppy

  - by Aimad Majdou

  I have a problem with flash player. HD videos from Youtube or Vimeo and flash games do not play smoothly. I'm using Flash player 11, Windows 7 Sp1, and my graphic card is Intel GMA 4500. Device Manager shows me that all drivers are installed on my computer, so i don't have any problems with drivers. When I run Google chrome, Resource Monitor shows me 15% ~ 40 % of CPU Usage and 40% used Physical Memory, but when I watch a video on Youtube or play a Flash game, the Resource Monitor shows 70% - 90% CPU Usage. Also, when I run some HD Video (Frame width : 1920, Frame height : 1080) on my computer, Device Manager shows me 80% ~ 100% of CPU Usage. before I Reinstall Windows 7, HD Videos and flash games were play smoothly I hadn't any problem with them !! I hope all these informations are enough to answer my question.

• Freezing with black screen after booting OS with AMD Catalyst driver

  - by Oleg

  I have ATI Mobility Radeon HD 5470 on my HP laptop. A few weeks ago I was confused with a weird trouble in proprietary drivers for my graphics card. When I start X server (or just boot Windows) system sometimes totally hangs up with black screen. The most annoying thing is that issue appearing is absolutely random (2 success, 3 fails, 1 success, 7 fails, etc.). It appears both on Linux (Arch, Debian 7) and Windows XP. I've tried reinstalling OS, drivers, etc. I've also tried updating BIOS. Then boot was successful for the next few times and issue appeared again (probably it was just a coincidence, because another BIOS updates gave no results). I really don't know what to do. Any ideas?

• ASUS EAH4670 vs. ASUS EAH4670 V2 -- Whats the difference?

  - by roosteronacid

  I've been offered to buy a used ASUS EAH4670/DI/1GD3 graphics card. I went price-scouting to see if the offer I was given was fair, and I found out that there's a similar card, labelled ASUS EAH4670/DI/1GD3 V2. Question is; What's the difference? What's with the V2? What does it mean? Is it just a BIOS upgrade that I can do myself? Updated driver-software which I can download myself? Or is the card actually a better version--faster, more reliable (physical changes to the print), etc.?

• cannot install new drivers for ATI Radeon HD mobility

  - by mugetsu

  I have an ATI mobility Radeon HD 3200 graphics card with a driver that I downloaded from my computer manufacturer's site. I wanted to upgrade the driver so I downloaded the respective driver from ATI and ran the installation. However, the installation only installs the download manager, the App SDK, C++ distributables and CCC, no display driver. When I try opening the CCC, I get an error that quits the CCC, something about the display driver not being recognized. What is wrong here? How do I go about fixing this? thanks

• LCD problems: brightness / contrast blown out, can't bring up menu

  - by davr

  Yesterday, when I turned on my LCD monitor, the colors were very very bright. It looks as if someone had gone into the monitor on-screen-display and turned up brightness & contrast all the way to the max. Colors were washed out, and it's almost painful to look at. So I tried to go into the menu and see if the settings were wrong somehow...and I found that I cannot bring up the menu. All the buttons on the front of the monitor now do nothing, except the power button. I was able to go into my graphics card settings, and turn the brightness way down to compensate, so it's at least usable for now, but it's not quite right, there is definitely some loss of color resolution or something from the two extreme settings canceling each other out. Any ideas what kind of failure in the LCD might cause this? According to the control panel, the model number is: KL2490DW-D It's a 24" 1920x1200 with the brand "synaps".

• nVidia Control Panel Won't Recognize SLI

  - by Nakaan

  So yesterday I bought a brand new, 1,000W PSU to replace my 650W one and to allow for SLI. I install it and my second card (both are GTX 560 ti cards). I reinstalled my drivers and my system recognizes both cards. The control panel says "GTX 560 ti x2", I can select between them for Physx, sound output, picture output (although I only have one hooked up to my monitor), etc. But the kicker is I can't turn on SLI. Everything I've read says I'll get a balloon notification saying I can use SLI and the control panel will have a new section, etc, but none of those things happens. Anyone have any ideas? System: Win7 Professional x64 2x GTX 560 ti 3.1 GHz Intel Core i5 1,000W Xion PSU 8GB RAM (Can't think of my motherboard right now) Note: My PSU and MOBO both say they're SLI certified and I'm using an SLI bridge. Edit: Formatting changes

• Diagnose Slow Video Playback during Editing [closed]

  - by chadejah Hunter

  Possible Duplicate: I Want To Start Editing Videos But My Computer Moves Slowly I am using Windows 7 Home Premium on a PC with AMD 64bit Athlon Processor 2850e @ 1.80GHz, 2GB RAM, and a NVIDIA GeForce 6150SE nForce 430 graphics card I am using Pinnacle Studio 15 HD Ultimate. While editing videos the program moves normally but the playback is slow. When I press play the sound is normal but the picture is really slow and choppy. When the sound ends the picture continues to play and it speeds up. I updated the video card today, restarting the PC but get the same behaviour. Does anyone have any suggestions what I can do to get video working smoothly while editing?

• What is Light Peak

  - by Jonathan.

  I've heard this a lot recently, todo with Apple and Intel. Some says it's a protocol, others say it's fibre optic, and others say it's copper. One source even said it was a "wireless wire". Apparently it can carry data, but not video streams, surely the cable can't know the difference between 1s and 0s representing data, and 1s and 0s representing video streams. Or it will replace all the wires we currently have except power, another place said it is for inside laptops. Those are just examples so I haven't given any sources, I just want to know what on Earth Light Peak is?

• How can I be sure that the motherboard is dead and it's not another issue?

  - by Peter

  So I have and old computer with and Intel D101GGC motherboard and a pentium 4 cpu and award bios, with a long repeating beep and not passing POST. I tried: RAM checking, they are good and working on other computers Replacing the PSU with a tested one, and still having the same issue I assumed that the CPU is dead and tested 2 others they are both Celeron D processors I also tested the CPU of this computer on another one and it's working fine I also tried it without RAM and still have the same long beep I did all this after disconnecting all the other hardware like HDD and DVD drives. The only time I didn't get any beeps is after removing the CPU I don't know if the processor is needed for the beeps to work. So My questions are: is it normal to not get any beeps if we don't have a CPU installed ? am I missing something or is the motherboard dead ? and thanks in advance.

• Second video card (PCI) under Windows 7

  - by dbkk101

  I'm trying to get an old PCI video card (Diamond Stealth 2500) along with a normal PCI-E video card. In BIOS, there is a setting to switch between PEG/PCI or PCI/PEG on startup (PEG is PCI-E Graphics). When I use PCI/PEG only the old PCI card works, when I use the other one, only the new PEG card works. In PEG/PCI mode, Windows 7 recognizes the card and shows it in Device Manager as Standard VGA adapter, but it shows a warning for the device ("This device cannot start. (Code 10)").

• Does it mean video card is broken?

  - by Sejanus

  Hello, I've just installed some sort of relatively old video card and now computer freezes while playing certain video games (Civilization 4, HOMM V). Some other video games with far better graphics works well (Dawn of War I). Note that "freezing" games runs nicely and smoothly for about 10-15 mins, no lag or any other indication that video card may be not good enough. And then PC suddenly freezes, nothing works but rebooting. The question is, is this a normal behavior of a video card which is simply "not good enough" for the games in question, or is there something broken? Card itself or motherboard or whatever? OS is Windows 7 if that matters, and I don't know exact videocard specs but that probably doesn't matter for this sort of question... thanks in advance!

• Makefile fails to install file correctly, installing HPL

  - by zarose

  I started installing HPL a while ago, and had a related question. I've been following along with this guide from Intel. I figure this warrants a whole new one. When I try to make the archive, the output seems fine until the end, where it gives an error. make[2]: Entering directory `/hpl-2.0/src/auxil/intel64' Makefile:47: Make.inc: No such file or directory make[2]: *** No rule to make target `Make.inc'. Stop. make[2]: Leaving directory `/hpl-2.0/src/auxil/intel64' make[1]: *** [build_src] Error 2 make[1]: Leaving directory `/hpl-2.0' make: *** [build] Error 2 Going to the directory /hpl-2.0/src/auxil/intel64 shows a file, "Make.inc", but it's highlighted red, and the white text blinks. Is there a way to manually make that file? What do I need to do to get the makefile to do this for me?

• Virtualization of desktop

  - by Agares

  Hi! I'm thinking about virtualization of my laptop(for educational purposes). My idea is to install very light host OS and have all the rest as virtual machines. Microsoft's Hyper-V Standalone would be very good solution, but it's impossible to access virtual machine from computer, where the Hyper-V is the host(isn't it?). So, which virtualization software would be good for me? I wanna have virtualized Windows 7(and maybe some other windowses). My processor support Intel Virtualization Technology.

• 2 GPUs (for multi-monitor setup)

  - by A Dwarf

  I have a machine to which I need to connect a second monitor. This machine currently hosts a ATI Radeon HD 4770 with two DVI adapters. The second monitor to be hooked to this machine is a VGA monitor. Until I find a DVI-VGA adpater, I'm thinking installing a second graphics card which does have a VGA adapter, an NVidia card. Can I successfully run both AMD and NVidia cards on this machine? Any specifics I must be aware of, like how to ensure the ATI card to be the main card? Operating system is Windows 7

• Need advice on PC components for high-end games but in limited budget

  - by Md Atif

  I need advise, I want to buy PC components which will be good for gaming as well as be under my budget. First thing I chose is Graphics card : ATI HD 7850 2GB DDR5 then matching things up with this selected following: Processor: AMD 3.5 GHz AM3 FX 8320 8 Core Piledriver Mobo: MSI 990FXA-GD65 RAM : 8GB DDR3 (4x2) Is this setup looks compatible? If making any of above component inferior will have negligible affect on performance/gaming(like buying 970 chip mobo instead of 990) then please let me know so I can save some money :) ? Any other advice?

• Memory compatibility?

  - by nvillec

  I'm in the process of building a PC intended mostly for gaming and I've got a few questions. Currently, I only have the motherboard and CPU: Motherboard: GIGABYTE GA-Z68AP-D3 CPU: Intel Core i3-2120 My main question is about memory compatibility. I have 4 Hynix 2GB HMT125U7BFR8C-G7 with light-moderate use laying around and I'd love to save a few bucks if I can. I've read that this is server memory... a) Will that be a problem for PC use? b) Is it compatible with the motherboard? I've emailed Hynix and checked Crucial to no avail. If incompatible, what memory would be a good fit given the components I have? The motherboard has 4 sockets and supports up to 32GB, but I don't know that I have the budget for that at the moment. Thanks!!

• How can I get my Sapphire Radeon 7850 to output in "1080p"?

  - by Fr33dan

  I have a Radeon 7850 connected to a Vizio 3D compatible TV. The TV has a function to parse and display SBS encoded content. On my old graphics card (a Radeon 5770) I just had to select the 1080p option in the catalyst control center. In this mode my TV reported the output mode as "1080p", with the new card the TV reports "1920x1080". I cannot figure out what the difference in between the 2 signals but the "1920x1080" cannot be switched into 3D mode by the TV. Weirdly, before windows starts the (in the Bios and so forth) the computer outputs in "1080p" so I know the card is capable of it. As soon as the blue login screen comes up though it changes back to the "1920x1080". I've tried everthing I can think of. Updated my drivers from 13.3b3 to 13.4, then even tried the 13.5 beta (Which I'm still on this moment). Tried all the "optimized" HD settings in catalyst, even the 720p modes show the resolution from the TV and not the "720p" (which it used to do on the old card when I had to lower the resolution of games)

• Moving data to lower sectors on an SSD without defragging

  - by David Freitag

  I bought an Intel SSD drive a while back and now I want to dual-boot with it. But for some reason there are sectors near the end of the drive filled and I can’t seem to find a way to remove the data so that I can safely shrink the partition. I know I have sectors near the end full because I am using Defraggler to analyze my drive (not to defrag it). I can see what files need to be moved/deleted but short of actually deleting some drivers and/or other necessary files, I am completely stuck. This the diskmap: I am only able to shave off that last 1.72GB of space from the drive which isn’t even enough for the most minimal Linux install.
