I’m posting here because I want some help, hardware forum is hardly used.
My friend just finished building his new PC. Q6600, eVGA 750i, 8800GTS 512 g92.
He is NOT using SLI, just 1 8800GTS 512mb video card.
After it was all put together and booted up (with up to date drivers) I decided to test his gaming performance on CS:Source. The frame rates jumped between 5 and 275… It was running extremely badly. The processor and video card temps were normal.
After testing my own working 8800GTX and having the same problem I went into Task Manager and disabled the bottom two cores for hl.exe under the process list. When I ran CS:Source the game ran smoothly.
His power supply is 500W but it lacks an 8pin connector to connect to the motherboard cpu power connector. All his power supply has is a 4 pin connector.
Could not having the 8 pin connector be the problem? If so, which is a good solution, buying a new PSU or getting a 4pin to 8pin converter?
If not, what could possibly be causing in game frame rates to go wild, making the games unplayable unless you use only 2 cores?
Summary:
Games run between 5-275 FPS constantly, making them unplayable.
Tested 2 video cards and both have the same problems (1 is known to work perfectly).
Current solution is to disable 2 cores through Task Manager and games are playable.
8 slot CPU power connector only has a 4 slot power connector in it. (Could this be the cause)?
I have 0 experience with SLI motherboards, is there anything I need to setup to make sure it isn’t trying to run in SLI mode?
Thanks for the help!
We both should be at the LAN tomorrow, so if anyone else wants to take a shot at this thing
. I didn’t have much time to troubleshoot it. Hopefully someone here can figure out what I missed.Kappamerc said:

I’d be happy to look at it during the LAN.
The 8pin aux is a dedicated voltage feed for the processor, to be perfectly honest, I’m surprised it boots into Windows at all without it. This is most likely the problem as the processor is only getting a fraction of the power it needs.
I’ve not seen a 4-8pin converter but with all the rigging going on today it wouldn’t surprise me if you found one on ebay. I would recommend that you spend a good $100 on a high efficiency, cable management power supply. By the time you spend a good chunk of change on a computer you might as well get a good power supply for it as it is just as important as any other part in there.
Ultra is suing every company that makes cable management power supplies and having invented it they have a chance (small) at winning so I would recommend getting one now from a good manufacturer because Mike can tell you Ultra’s own supplies suck.
Poked around and found this. It is 600w with quad 18A rails. It has both 4pin and 8pin AUX connectors.
Thanks for the advice, we’ll talk more at the LAN. I found a 4 to 8 pin connector but I’m not sure if it will actually pump more juice. I have like 3 converters that converter regular power connectors into 6 pins (for video cards). I wonder if I can find one of those anywhere.
Either way, I agree with you, new power supply was my original suggestion to him.
