At least my games run on max though.

try flashing with toxic bios on the vapor-x card

when you guys test in Furmark, do you just run the bench or stability test?

coz i run the bench, and all is stable. in game, all is stable, max temps are around 70 on the core in Furmark, 78 for the ram.

but if i run stability test, the GPU VRM (whatever that is) goes up to like 95 so i quit straight away. even with the fan on deafening 100%.

no games make the card that hot, so what does the stability test do besides the obvious?

[JTP709]

The Furmark stability test is like the Prime95 of the GPU world, it tests the GPU to its limits to prove rock solid stability. I agree, few games will ever push it to that limit, but after many many hours at a lan or just playing something like Crysis or Arma2 all day it can really stress out the GPU much more than a minute long benchmark test.

i run the furmark on stability test. i get around 68 max on my gpu. but wow ur temps are really high.

How long ago did you get this card? With a non-reference cooler you should be idling around 40*C and maxing out at 70*C(ish) under load. I think this card is bad enough that it's worth an RMA. Even if you didn't want to OC it, temps like that are bad for your whole system because they raise the temperature on the inside of the case. It won't kill the card as 4890s run hot... but that's still not good.

yeah i know. they are only that high in the stability test when i run 960/1030 and above. not at stock.

but yeah, i figure it has survived repeated Furmark benches, Crysis, and other games, so its stable i dont play more than 2 hours max at once anyway.

10 loops of crysis bench will tell you if your gpu is stable

totally agree. ur temps are way to high for a non reference pcb.

according to Everest anyway

Yeah. Fan speed is also around 45% - 50% for me. Around 60c idle, don't think it goes over 70c on gaming but haven't tested.

But this noise is not from the fan I think.. it's those electronic stuff.

Nobody else get noise? Electronic noise say buzzing during gameplay or when scrolling web pages/documents?

lol why 10? im gonna run that bench but it acts funny coz i have the RealLife mod installed.

i swear though, playing Crysis before, im only getting like 7fps less with this thing @ 970/1100 than i was with Crossfire 4870s @ stock.

must be the 1gb of ram helping out, along with the massive clocks. compared to the 4870 clocks i mean.

that sounds like it could be transistor whining? my mates 8800 Ultra used to do it.
