What is max. VRM temp for this card?

What temps do you have, at idle and at load?

the stock voltage on your card should be 1.2 - 1.25v. aim for the best stock voltage overclocks in AMD CCC. i think voltage control is not yet available on HD 7870 Tahiti LE with sapphire trixx and msi ab. and with your cooler its also not advisable. keep core temps around 75c. VRM temps below 95c. you will in fact have to ramp up fan speed to maintain those temps when overclocking. as always aim for stability and longevity over raw speed. for stability testing heaven, 3d mark, bf3, crysis 2, farcry 3 are good choices. for monitoring core and vrm temps use gpu-z or hwinfo32. good luck thumb.gif





YOU ARE DEAD ON THE MONEY!! ihave the card and 1150 max and 1600 mem @ 80-100C vram temp in OCCT . vram at 110C shutdown.
