Random 'hard' freezes after overclocking GPU, is the power supply the problem?

post #1 of 7
Thread Starter 
Hello everyone.

After a couple of years of using my computer, I basically wanted to play a couple of game that it just couldn't handle at max settings, overclocking fixed that problems.
I already overclocked my Q6600 to 2.90Ghz and it is pretty stable, my GPU (Asus GeForce 9600GT) also is pretty stable.
But sometimes I get a hard-freeze, there are no real artifacts on the screen except for that a couple of pixels have different colors.

My power supply is some generic Aopen, the label says 400W peak.
I know this is pretty low, and I think it is the problem, but can somebody confirm it?
I overclocked using MSI afterburning, and due to me not having enough time to properly benchmark, so far the freezes have been in a game which has punkbuster.
Now I heard somewhere that punkbuster messed up with MSI afterburner but I guess that is fixed since the problem was pretty old.

My Setup:

Asus P5KPL-VM
2 sticks DDR2-800 RAM (4GB total)
Asus GeForce 9600GT (with the glaciator heatsink/fan)
Intel Quad Core Q6600 2.40Ghz (OC to 2.90Ghz)
The other things are onboard.

Greetings,
MasterMe.

Probably the PSU. I found one reviews on yours, but you need a quality 450W+ PSU for that card, considering you OCd your card and CPU.

You should also try using the AB beta and changing the settings on low-level hardware access.

You can probably get that 6600 to 3.6 once you get a new psu.

Well,PSU's do degrade over time,but that doesn't mean that's your problem.If it ONLY happens when you run Punkbuster,well then there is your problem.Have you installed the latest AfterBurner?I would also look at your temps,as heat can cause the same issue.

How should I set this up, I have 'user mode' and 'kernel mode'. I currently have it on kernel mode since it says it prevents punkbuster from being retarded and messing around with GPU.
Also the bios of my GPU is 62.94.11.00.00, but I think flashing GPU bios is not a smart thing to do.

The cpu is always <65 degrees now, but before I cleaned my heatsink it sometimes reachted 96 degrees, it never BSOD'd though.
Currently when I O.C. it to 3.0Ghz I get BSOD when I start stress, could this be the PSU or my motherboard?
I don't have direct control over voltages in the BIOS, it has some stuff and it says "Change FSB speed and all other parameters will be adjusted automatically", does this also include the voltage of the CPU?
I heard some stuff about custom bios, but I don't have a fan on north or south bridge and I don't want to motherboard to die since I'm saving up for an entire new pc.

I always keep an eye on the temps, I have a G19 and I put a lot of data on that little screen (Click here to see it).
It never overheats, max temp while I was stressing for 10 minutes was 55-56 degrees.

I'll probably grab a new PSU in a couple of days, I'm saving up for a new PC but I guess I can get the PSU early.
I have a question now: Around how many watts does a new gaming PC use, a i7, GTX590, etc. I also want to be able to put SLI in later without having to buy a new PSU again, I'll buy a very good one right now so it'll last a couple of years.
Can you guys recommend some good PSU's, all I care about is that they are modular and have good performance, I really don't care about noise.

EDIT: After enabling Low-level hardware interface (kernel) in the MSI afterburner beta, it stopped crashing. I do however, notice that the GPU is simply not maxed when it should generate more frames to keep it stable, not the optimal solution but I think it's better than crashing every hour when playing a game.

MasterMe.


On a side note: I'm really, really surprised about how fast I got a response here, and even 3 responses! Awesome forum.

No problem mate.A decent 650w will cover any single or mid-range dual card setup.I would grab 750w-850w if you want extra headroom,but it's overkill.
OCN has a rec. PSU list as well as a PSU calculator to determine your exact needs.

Thanks for the info, I bought a Coolermaster Silent Pro Hybrid 1050W since I know that when I grab a new PC in around 6 months it will be good enough to let me do whatever I want.
