BSOD at 39C!?

Hey all,

I decided since I've got my temps down to a pretty safe level (60C max while playing Fallout 3 on Ultra) I'd try my hand at OCing again.

I was able to OC to 600/1550/900 on my old drivers, and now I've got the newest 185 drivers and thought I'd try that setting. With my fan on my temps were idling just under 40C with those clocks, but as soon as I loaded Vantage, my comp BSOD'd on me. I thought high temps were the biggest problem with OCing, but apparently not.

What's the next lowest acceptable clock for the 9800m gtx's? Temps aren't a problem for me, so my OC speeds are obviously jacked up, or having some type of conflict.

 

Have you undervolted also?

 

600/1500/950 are always safe but you need to overvolt to 1.05 otherwise they might be unstable. On my machine system crashes or artifacts if I try those clocks at anything below 1.03V.

 

negative, I thought about undervolting, but after running orthos for 10 minutes only one processor hit 60C and the rest were around 50C.

 

What's the stock voltage? and also, what's the most stable OC for stock voltage?

 

Great...I think I'm having driver problems again. The first time I installed 185.85 hl2 would crash everytime I played it. So I reinstalled my drivers and everything worked fine...now Fallout 3 and hl2 are crashing again. This is getting rediculous. I think I'm going to go dl the dox drivers and test this.

 

I dont know for your processor, but you can use rmclock or cpugenie to find out. For me, CPUGenie is the more useful of the two(it has a feature to automate the process, no guessing and testing for each voltage). You only have to pay (cpugenie) if you want to get rid of annoying notification(that it's not free) at boot.

 

RM's got my stock CPU voltage at 1.300v

 

You can use the same process for overclocking- at least that's what I've read from the undervolting guide-

 

...I just dl'd vista7x86 drivers...that should be 64 bit, correct? well theyre not, now I have to go dl the right ones...why cant things ever just work?

 

x86 indicates 32-bit. x64 indicates 64 bit.

 

One of the factors that is causing your system to crash is your core/shader ratio. Drop the shader back down to 1500Mhz and try again at your stock voltage of 1v. If the card is still unstable, raise the voltage.

Nvidia and Dox's 185.85 are pretty stable and shouldn't give you any crashes, atleast in those games, and providing that you downloaded the x64 version.

 

I assumed that since all my programs were under the x86 folder, that that indicated 64 bit, but I guess I shouldn't make assumptions.

downloaded the right one this time, as well as Nvidia Physx. I'll put them back on today when I get off work, and test the temps and what not before I go about OCing again.

I'm thinking I had a bad download of the 185.85 nvidia drivers because after I'd install them, they'd work for a few hours of gameplay, and then crash. After the first crash, anytime afterword I'd open the same game it would immediately crash. This was at stock clocks. Hopefully this will finally resolve my issues...if not I might just go back to my default drivers...scored a lot less on 3dmark, but at least I didn't have any problems.

 

x86 drivers are for 32 bit. x64 bit are for 64 bit.
