Things to note:
  • Clicking on the OCCT rendering window (so it's at the *front* and currently highlighted on your desktop) will allow it to run full speed. Clicking any other window or item during the render will cause it to automatically downclock to 20 FPS. Simply click the OCCT render again to resume full speed.
  • You can determine how much pressure it puts your card under by a) setting the 'FPS Limit' or b) re-sizing window after the render has begun. Bigger = more power hungry.
  • Don't go daft with 700++ FPS etc lol, try to simulate a real world scenario (make the window a bit bigger to keep FPS down while still drawing a typical gaming power draw (maybe 275w)?? Utilise FPS limiter.
  • Play about with window size after it's begun to 'perfect' your run.

My max stable memory overclock is 12,120Gbps

Anymore questions don't hesitate :-)

Well, everyone on this forum seems to be getting to around 2000mhz (sometimes at stock) as a baseline so any gains above that are single digit percentages. The VRAM is another story, you get roughly half of your percentage overclock as performance with VRAM (so if I OC my VRAM 10% I get roughly 5% perf gain), but where it really helps is the minimum frame rates, especially for open world type titles.

Its strongly recommended to OC the VRAM as its performance uplift is measurable and the power impact is minimal vs gunning for higher voltage augmented core clocks. Some members even noticed massive VRAM OC headroom just be simply beefing up the VRAM cooling.

Only 3 weeks. No visible leak in my leak test. The crack is really small; it takes some time to really accumulate.

Don't know if the crack happened before or after the installation. Thid Acrylic Glass is really really weak, I never had this problem before with Acetal waterblocks.


Oh man. So sorry. Hope nothing is ruined.

Was the card powered on when it happened?

If not it might be fine.

Take it to a sauna and dry it out thoroughly then leave to sit on top of a warm radiator for a few days.

Really sorry for your loss if you've lost it. mad.gif

It black screened in the middle of a video playback, so yes, it was powered on..It's now bathing in the rubbing alcohol. Hopefully it's still ok.

ok, thanks man. i'll give it another round, even though i pretty much know my sweet spot is 11,880. i just want to confirm my tests and this should do it.

Finally managed to do stable Witcher 3 clocks... Playing 5 hours straight, no crash or anything . Nice and stable 2050 at 1.050V. thumb.gif

Seems like Memory OC was a reason of crashing. W3 don't like momory OC at all. Not only I gained 4C by doing lower memory OC but I didn't lose any performance.

Also seems like Temperature is really important. I used more aggresive fan curve- 65% and kept my card in range of 58-60C and didn't have any perfcaps or powerlimit at 2050 and 1.050V. Not even once clock droped below 2050mhz.

Uff...finally....

Tomorrow I will repaste it with Kryonaut and I hope I will gain 4-5C more.

So key is lower memory OC and keeping card under 60C. Which is not easy in W3 but with agressive STRIX curve totally possible.

Thanks all for all suggestions and help and big thanks to my man, @Slackaveli for Vram suggestion.

M final curve and AB settings:




I think its time to invest in water loop.

Could someone tell me what components did Jay use in this build? I have same case so I want to order exactly same EK Res/Pump and radiators:

Could you explain this in detail? I've heard others mention it before but I'm trying to understand exactly what you're doing. Are you dabbing rubbing alcohol onto the PCB or literally dunking it?
