MSI already tweaked the voltage limits on it some, so it allows significantly higher clocks on average than on most other cards at same silicon lottery status.

And yeah power limit can become an issue too. Most 1080's are limited to ~220 watts, even the ASUS Strix that has the extra 6 pin (seemingly due to needing a lot of that extra 6 pins wattage to run all the RGB lighting, the two 4 pin case-fan headers on the card, the triple fan cooler etc..etc..) only gets to just over 220. The better cards do a tad better on power, like for example the EVGA FTW 1080 hits 255 watts or so with max power target, my card can handle just over 300 watts at max power target.
Sooo... did you modify a bios or not?
water cooled... with cold water if needed. Warning: Spoiler! (Click to show)

Now I'm upping the RAM trying to get more than 3000mhz. Here's where I'm at right now.


nice job m0ok! thumb.gif

Yeah I can't seem to get it much higher than this for now (3074mhz), I probably can if I spent enough time tweaking and stuff but I think I've got it to a pretty damn good point which is stable and I'm happy with. Plus I have work to do! Need my PC smile.gif
Thanks, I'm pretty happy with the results and I think I managed to get quite a good 6950x chip! Watercooling was 100% necessary, tried to aircool it and even at stock speeds it struggled to keep it cool! EK Predator doing a great job now.
Final Stable results:

the thing with memtest is that it is really not made for assessing the stability of a ram overclock - basically it is good for determining if a ram stick is bad. HCi Memtest Pro is very good but would take geologic time to run properly on 128GB even with 20 threads. The only option we have to test ram stability with 64 and 128GB is Google Stress App test. 1 to 2 hours and you know for sure. thumb.gif

Thanks!

Yeah I noticed that when I ran Memtest overnight and realised that there has to be a better way (I was literally thinking, what do big companies do when they have 500GB+ of RAM? There's no way in hell they are Memtesting that for a month haha). So yeah when the Google one was recommended it all made sense! Will definitely be using that in the future if I get bored and I wanna see if I can get an extra few hundred mhz! wink.gif

to make that 128GB sing... dial up the cache a bit.

Haven't fiddled with that yet! Will see what I can do! smile.gif

EDIT: So far so good @ 3700. Stress test so far so good (only 10mins in). Will give it an hour then run Google Memtest if thats all good I'll stress it for 12hrs.

EDIT 2:

I love seeing this:

So. Much. Power. haha

AIDA64 cache test is still pretty good on BWE. Also, again out of curiosity have you attempted 1T? I'm doubtful this will work for you, as that's really pushing the limits. If so however, that would be very impressive! A memtweakit shot (or Gigabyte equivelent) would be good also

3700 is great!. Probably no need to go higher until/unless you go higher with core also. 42/37 and 43/37 seems to be a sweetspot. 44/38 is also very "productive". wink.gif

Question: how did you wind up with a BCLK of 102.5?
