As stated in the title, I have an x1900gt. It has been wonderful to me for a while, but now something has happened to it. You may have seen me post in a couple other sections in reference to this. So, back story:
I had this clocked at roughly 580/7(something) on stock cooling and volts. But I wanted to take it further since I thought this card had a lot more in it. So I found a nifty little volt mod. So now I have it running at 1.35v. With this I was able to get it to clock to 610/825 or so. But stock cooling was not enough for it and it was frequently peaking at 75~80c...unacceptable. So now I have it on a water loop with maze4 acetal top and a BIPII.
Ok, so that was awesome, it idles at ~33 and peaks at ~40 now. Water cooling rocks...yeah. But for some reason I am having problems with clocking it now. I can barely get past 580 on the core now. I don't get it, it seems to have clocked better with the stock cooler on it even though it was getting way hotter. I don't understand what happened. I haven't spilled any water on it.
One thing I did notice is that my PSU +12v rail was reading 11.88v in the BIOS. Is that enough of a drop to possibly effect my OC? My CPU and memory are OCed but a rock stable. Also, when I am trying to OC (using catalyst 7.3 drivers and ATItool) and it happens to crash because of me pushing the core clock higher, it does something weird. When I reset and Windows loads back up, I see the ATItool icon in the tray, like it is loading the driver....but it just sits there instead of loading and popping the temp up. Instead, it reboots, and reboots, and reboots. Not until I shut down completely and turn back on does it load Windows successfully. I'm starting to think it is a driver issue...
Any thoughts?
