OC problem

is it ok to OC my HD4870 to 850Mhz gpu clock and 1200Mhz memory clock with the fan on 80-100% always?

I meant that while it's OC'ed, the fan is always on 100%ziv_ew

what i askd if it can somehow damage the GPU crancking it up like thatziv_ew

well i did a quick test with metro 2033 and its about 44C but the game has grafic gliches (black squers on the textures, streachd modles etc.)ziv_ew

ok did the furmark thig and its about 54C max

btw im OCing with catalyst, but if theres enything better let me knowziv_ew

i have a set of sennheiser HD 280 pro that block out most of the noise even when theres nuthing on the pc that makes sound, and i hear heavy mtal music most of the time so i dont hear when peopel are near me screaming at me.

That GPU should run fine all up to 90c, i dont think it will cut out until you hit 115c!swehunt

just because you have higher voltage do not mean you'll have to keep it coolerswehunt

Lol, you don't know what you talk about, first we are talking about a GPU witch he won't be able to do anything to the core voltage without flashing biosswehunt

*facepalm* Seriously, more insults? I tried... If nobody with PC or electronic knowledge will go against that, then why did you? I didn't twist any words by the way. I proved my point =\superclocked

You wrote: "Try running your CPU at the same speed, but increase the voltage to about 1.65v. See how long it'll last without a really nice cooling system..." and: "Hmm, I soldered two resistors in parallel to IC's on each of my video cards to overvolt them to 1.22v..." and: "All silicon chips, transistors, etc. have voltage tolerances. You can't push 12v to a GPU just because you keep it under 115C. The increased voltage will degrade the chip. At lower voltages, the degradation won't be as bad, but it's still there..."

Are you sure you wrote in the rigth thread? I havn't contradict anything i wrote, but you are mumbling without any connection to what the subject is, you havn't proven a point you mumble about some CPU vcore and frying some random chip...

The fact is still the same, even if you cool the PU to sub zero temperatures wont help if the silicone leak as it'll do if you overvolt it to much.

Temperature in the normal range is preffered and low temps is a good thing, but 40-50c temps isn't rly needed for such an OC the TC has, setting the fan to 100% makes no diffrence since when the card hits it's 3D clocks and start pumping FPS the fan on auto has the range to go up to 100% if it feel any need to do so, i don't kno why you're hooked up on this and what in earth has that to do with you frying your CPU with 1.65volts?

I'll say it again: The most noteable diffrence setting the fan to 100% has for the TC is that the fan will be loud while keeping the card very cool at 2D clocks and most likely be worn faster than it should when leaft on auto, at 3D clocks the card alredy can and will go on full if theres need to do so with the standard auto setting.

Can you elaborate what you really mean as to prove your point, you've written many things but not prooven your point. :)
