I have a 7870 Myst aswell. Whats your temps like? Mine gets pretty hot even with a side case fan.


Here is a run of the Valley Benchmark @ 1230/1590

First off, MSI Afterburner seems to report my memory speed wrong, overclocking the memory by about 1MHz makes it report 1380MHz I think the ratio is off but not serious as GPUZ and other programs get it right.

Also the +20 power control is in the correct place but unless I select it and apply it again on startup it will really be at +0 and let the core speed flicker between 925 and 1000 (925/975 default), also the GPU usage on stressful games flicker between 60% and 100%.

Memory values been displayed by Afterburner @13xx seems to be common. I have it too.

(Powercolor Myst, .32 bios, 13.3 drivers)

Obviously a bug. GPU-Z reports it properly.


Anyway, my card is screwed. Every single time I try to start GPU-Z, my computer just freezes. Screen goes blank. Need to restart.

Massive artifacting at stock in League of Legends. Syndra's orbs are all screwed up. The 'recall port' on minimap artifacts.

Screen flickers like crazy. My windows keep resizing themselves and repositioning on 2D desktop in my web browser for whatever reason. I've had it for 5 days, and these problems have started up just now. Yes, this is at stock. Yes, this is in addition to all the other throttling and power issues that everyone else has.

This card is junk. I'm getting a refund.

You can try the .28 bios. Outside of high temps my card Myst has been fine. Link to .28 bios DL

Almost, 13.3 beta 2. Although if GPUZ and other programs can get it right I doubt it would be that. I'm not really bothered as I use MSI for OSD and frame rate limiting, besides I'm not a fan of memory overclocking.

Now that I'm crossfired, temps have gone up, but not that I've figured a few things out. The number 1 GPU is hotter than the second due to its location. It got up to 82C using MSI Kombuster. I also noticed that gpu 1 was being utilized much more than gpu 2. I then found out that I had to run all applications in full screen mode in order for both gpu's to run at about the same percentage. My kid just gone done playing 30 minutes of COD Black Ops 2 and GPUs temps topped out at 56C. I have to keep experimenting but I seem to be very lucky as others are having problems. Hope I don't join that club. jimbo

Cool. Do you have a dedicated VRM block or a block that covers everything?

Hi folks,

Have the 7870 Club 3d jokerCard- pitcairn version. Cost $200. Bought it before the Tahiti version was available.

Have an opportunity to get a Sapphire 7870 xt (boost) for the same price.

But I would have to go pick it up and then sell my old 7870. My problem is I can't figure whether the trouble of picking up the new one and selling the old one is even worth the improvement in performance.

Would you folks bother with it?

Thanks!
