That's a nice score but I want to ask a favor. I see you are running 1200/1625. My PowerColor Myst overclocks very well, except for the memory. When I raise the mem over 1500, I actually lose points in 3dmark 11. I now have crossfire, but when I ran my one Myst, I overclocked the core to 1253 ( i believe, it was close to that) and left the memory at 1500. I believe my 2500k was overclocked to 4.5. My score was P9614. That is with stock voltage and 20% power limit. Could you try those settings in 3dmark 11 performance and get back to me? Also, do you have the 028 bios like I do? I love this card and that's why I bought another and crossfired them. Gotta love it...P13300, graphics score over 17000. These cards are beasts and I beat my son's overclocked Sapphire 7970 vaporX with 3770k by over 2000 points in 3dmark 11 performance.

My card doesn't like anything over 1200 at stock voltage and using the beta afterburner unlocking the voltage and setting it at a constant 1.3v only gets me a small bump up to 1225/1625 http://www.3dmark.com/3dm11/6280309

When/where did you buy from a batch of 32's?
Please explain what you mean further, stupid me can't quite grasp what you are asking tongue.gif.
The .32's came from NCIX which is a relatively well known computer site. At least in canada.

is the stuttering core clocks a pretty common issue? I've tried the .28 (came with it), .30 and .32 bios' and they all stutter while using kombuster. It is driving me nuts right now because i noticed that my gpu usage is also spiking all over the place at the same time as the core clocks...

oh, this is with the myst.

Yea I've got the same problem. I fixed it by turning power control to 8%.

GPU usage can jump if your CPU is bottle-necking. Personally, my core stays solid and usage as well unless i'm in a less-than-demanding section of a game. A good way to get full usage is to set AA to edge based and use MLAA. also use vsync in AMD CP not the game.

I have a question guys. My powercolor 7870 just got here

I'm switching from the 6950 in my sig rig to this 7870. since they are both AMD.....do I still need to mess around with all the driver nonsenese?

like why would i need to uninstall it if id just reinstall it two minutes later exactly the same since they are both AMD?

I'm currently on the 13.3 beta drivers if that helps answer. thanks guys i need to get this bad boy in my rig so help quick if you know lol

and then I can join the price/ performance smart buyers club haha!

edit: also running windows 8....

I went from a 6570 to a 7870 XT without a driver re-install and I had no problems. I would recommend you to re-install the drivers, though.

Nope....no driver changes required! Just pop in the card and fire up your machine. It should automatically show the new card as the primary graphics device. I can say this pretty confidently because I have done it before on other AMD card....(I am still waiting for my Tahiti card to arrive)
And though I use Win 7 64bit Ultimate (Win 8 sucks!), most likely it should be no problem in Windows 8 either.

@MrMaxout

If you are reading this, please enlighten me/us how the heck did you reach those core/memory speeds?! I literally had to do a double take! 1425/2000!!? WOW, frickin' unreal! Can you post your 3dMark11 scores, idle/load temps please? You must have gotten the best/golden piece of the Tahiti board!

thank you!! up and running on the new card haha

no problems so far, I did uninstall then re-install just to be safe. card idles at 41 ish in my case and just fired up far cry 3 for like 15 minutes and hovered around 62 C so not bad, just about what my 6950 was at.

frames at stock were underwhelming though lol. only 40 fps dipping to 30 (but I know far cry isn't optimized that well. So I'm about to jump it t 1150 on the core as a starting point after i read through this thread, and report back, hopefully it does not disappoint smile.gif

thing is loud though!!! lol 40% plus and its getting like a blower lol. my old 6950 could go to 70% and not hear it lol.....but like I said hopefully in a few minutes I'll be crushing its fps devil.gif
