Hey, I tried these timings. Not only they work, but I managed to get +100mhz stable on ram. What the hell?
I gained 20 points or so in Heaven. Great!

Edit: Is it okay to have something like 1,0000000+ errors in random blocks when doing memtestCL?

Edit2: seems like errors are reduced if I reduce ram voltage. Again, ***?

Okay, tried few days mining with 1500 timings copied over the 1750/2000 ones. Started okay, but ended really unstable. Switched back to stock BIOS. Decided to try the MemTestOpenCL. 1st iteration, 0 errors. 2nd itteration gazilion of errors, nothing gives where the errors are.

Ideas on that? Bugged bench or destroyed my memory?

Alright I have a question. I edited my vbios yesterday using polaris and now for some reason windows isn't recognizing the device drivers. I have a 8GB OC Asus Strix. I didn't mess with anything but the tdp and power limits. I had to reflash the stock bios and now it recognizes the driver again. Any ideas as to why this is happening or how I can overcome it and successfully flash the new bios? Thanks. redface.gif
Peace

MemTestOpenCL is ~2010... It has problems even with GCN 1.0 cards.

Different timings can't damage the hardware

After flashing, you'll also want to ddu and reinstall but before you restart after reinstalling the drivers run the patcher then restart.
