gpu@1493/7860 with the cpu@4.5

Were you running win7 for ivy and win10 for skylake? I think win7 may do better with this bench.

I thought I was using Windows 10 for both benchmarks, but looking at the results I guess I was using Windows 7. Very interesting. Here is the link to the 22k one.

Just ran a test, normal Firestrike puts out 24590 w. 980Ti SLI @ 1442 MHz core, 1872MHZ mem, 5930K @ 4.44GHz coupled with 2x8GB 3040Mhz 15-15-15-35 ram.
Graphics score was 36004 but can't validate it as I have a DL'ed serial (ain't nobody got time for demo's biggrin.gif )

EDIT: That's because I was going up by 25MHz and 50MHz on memory. Increments of 5MHz does eventually cause the snow flakes to show up, before the crashes and hard locks.

VRAM is difficult to destroy nowadays, as Windows has hardware level driver protection, and your system will lockup well before any permanent damage occurs. VRAM voltage does not change on the board unless you're using a really high end PCB; damage only occurs when overheating occurs or forced electromigration from extreme voltages. The VRAM on the 970 is small enough to be easily cooled by the stock fan profile, so unless the fans stopped working, VRAM is safe.

Modern cards will downclock or halt well before any permanent damage occurs. The only thing that they can't protect against are overheating VRMs or damaged circuitry.

Ok so how common do people oc their memory to 7900-8000 on a ti?

^with samsung vram - it's practically a guarantee.

This is weird, by slowly inching up, I've been able to stabilize 8200MHz now from 8GHz. Must have just slapped on 8GHz and kept it there. Mine are HyniX. Ran Witcher 3, BF4, Metro Bench, FF Heaven, Heaven, all to verify.

Ok I have samsung ram. Gonna see if I can get 8000.

You guys run 8000 24/7?

What causes the screen to suddenly jump to light gray, too high core or vRAM overclock?

Yep, and now 8.2GHz wink.gif

If it doesn't crash, then it's the memory. Back down another 10MHz or so and see if it goes away.

My hynix memory is absolute trash. It doesn't go past +75 at stock voltage and power limit.
With the powerlimit completely unlocked and voltage set to 1.237v it can't go past +200 and even then I haven't done extensive, week long gaming on that to see if it's 100% stable.

7800 gpuz


7900 passed. 8000 got the red specks and then crashed. Gonna keep it at 7800 I think.
