I think it's the cooling. God knows what kinda glob they put under that headsink on the GPU. and the thermal pads on the ram modules might be causing problems too. A direct contact with that copper heatsink and some AS5 should seriously improve the results.
It has for my x800GTO, and my x1950pro in the past (both agp HEHE)
ALSO: Card is NOT stable above 60 temps...not when oc'ing anyways.
ty for being the brave soul to flash using the 1.377 bios! We just need to verify it actually is increasing voltage, though I do not know of measure points.
Once I get back home tomorrow from Thanksgiving break, i'm going to modify the bios and try running 1.4v. It should be pretty easy to tell if it actually is feeding more volts to the gpu if your temps under load are higher than the same clocks on the stock unlocked bios.
As far as cooling, there are ton of good coolers out there. Anything that fits the x1900xtx should fit the 3870/50 perfectly. TBH, the stock thermal paste job looked fairly decent when I removed the stock heatsink and replaced it with an Accelero S1 a week ago. The problem is the size of the heatsink. You'd think that a dualslot cooler would have a beefier heatsink, but that thing is pretty measly.
I must be a fortunate one because I am able to hit 877/1314 artifact free and run up to 905 core on Fur. Can't wait to try voltage testing tomorrow when I get back
