Still locked at 1.3v here as the maximum. Its always been 1.3v max for the 7870 though, im not sure about the 7850.

Memory can go to 1500, but 1450 vs 1500 makes no real difference IMO.

No, its cooled with an H70, and a 90mm fan blowing over the VRMs and its not the OC version. It's also BIOS flashed with the Asus BIOS to allow voltage past 1.225v

Has anyone tried using the H.I.S. overclocking software? I personally have used the Trixx and the Afterburner, and have tried the GPU Tweak. Personally, some of 'em are a pain to use, too complicated for just a simple overclock, and others (like Trixx) don't allow changes to much at all but this HIS overclocker seems easy to use and does all that I need to do. Wouldn't have even known it existed if I hadn't gotten a deal on these 2 7850's and accidentally clicked on a link on an e-mail from them lol. Anyway, just wanted to put that out there as someone may be like me and not want to have 1000 different dang things in their GPU overclocking software like MSI's and Asus's. Have a good one!

When you add a GPU does it effect you system OC? My saved bios overclocks work up until 5.0 then i get blue screen . Is that normal? I am assuming the second card effected the balance in system.

Man, you have a 7870? BTW, what's a real 7870 vs. ??? I am not sure what that means...unless there are 2 different GPU types or sum'n (from the post after) Anyway, how'd you get such a great score? I only got 6500 with my stock 7850, with a stock I5 3570K and 4 x 2gb of 1866 dominator, but I guess maybe overclocking... I need to get this one optimized before adding the 2nd HIS 7850 in c/f to get all I can outta them. I wonder, do you know if this Lucid MVP software affects the performance neg. in 3d mark benching? Thanks

He has the tahiti based gpu 7870 version. overclocks like a dream.


@Mates Rates. Nice overclock for your card. Was able to adjust votlage with msi afterburner beta 7 and was able to unlock voltage monitor following your turtorial. My highest core clock was 1230mhz on 1.256v stable in btc mining, but damn card runs too hot so now mining on stock clocks and voltage with 100% fan speed. Top card hitting 77c while bottom stays at 65-67c. Btw these are powercolor mysts edition with their crappy pcs+ coolers. Probably try 1.3v under water and see what i can get on these cards.
