Nope, but I did try the "new" 1.50 for the taichi xe. The upgrade wiped out the OC profiles, and also the UEFI boot entries for anything else than Windows. If you're a Linux user like I am, you can GFY.
For the OC profiles, be sure to backup your OC settings, there is an option for that in the BIOS. Glad I posted screenshots on top of the previous page... And for the UEFI entries, be ready to boot over a USB key, chroot to your linux setup, and (re)apply reFInd or efibootmgr. Pity.

No i'm on win 10 64. Thanks to inform me about loosing oc profiles. I'll try to make a regular back up through bios and screenshots by myself. Today i saw they posted 2.20 version up. I'm at 4.7 absolutely stable but i'm tempted to upgrage hehe

Anyone seeing bclk fluctuating on the x299 taichi xe? Seeing this in cpu-z. I mostly see from 99.xx to 101MHz. Sometimes up to 103MHz while benchmarking.

Anyone else seeing this? This is with c states and speedstep disabled. Tried both auto and 100 BCLK. 7940x all cores running 44x100 -4 avx. However it dosen't seem to cause instability.

Non-Delid 7980XE, But I have Swiftech 360mm AIO w/ GC Gelid Xtreme, GSKill 64GB 3200MHz -14, ASRock fatality XE

Want to overclock to 4.5GHz All cores, possibly 5GHz on 6-8 cores for gaming. I don't know any of the specific settings to adjust. I am used to only overclocking BLCK, multipliers, and voltage...
I am not sure to have constant 4.5GHz or not... I want to be stable, but I am willing to push voltage to 1.3/1.4ish, I am not sure what voltage or high temps are safe for 24/7 use.

If someone can look carefully at my settings, and tell me which exactly to adjust and change, that would be great help!

Also looking to OC my ram to 4GHz after finding a stable cpu oc.

Noticed the same thing couldn't find a way to fix it and as you say doesn't cause any instability.

Hope you guys don't mind if I hang out here, although I have an X299 OCF rather than a Taichi model. (The OCF thread looks pretty dormant, no other posts in a couple/few months except mine).

Features seem to be pretty common between these 2 models.

(Re)built my rig with an OCF and i9-7940X after my Asus X99-E WS / 5960X rig fell over this summer. Just started working on the OC for the OCF/7940X this weekend since I have had downtime for a few days. Am up to 4.6 (all cores) right now on water, using adaptive with a negative 0.055 additional offset value that seems to be pretty solid. Vcore is peaking at right around 1.200 under bench/stability load. Gettin ready to work on mesh.

I have seen some minor fluctuation with reported BCLK in monitoring tools while tuning this weekend on my OCF but not too worried about it. I have C-states and EIST enabled.

I don't rely on CPU-Z too too much, I do use it for general info etc. but I have seen others say it isn't always giving 100% reliable info, and I try not to run it while doing benchmark/stability tests because I have seen it crash my system a few times in the past. It might not be CPU-Z's fault, I generally have HWiNFO64 sensors running too. I have stopped trying to run >1 sensors probing tool at a time if at all possible, so it can be ruled out as another reason for crash/hang/etc during OC stability testing.

@Scrimstar I am not a highly experienced or accomplished overclocker (and just got started working on my 7940X this weekend) -- but with that core count you might want to be careful about going that high (1.3 - 1.4v) with the VCore. I'm basing that one on doco I've been able to find on X299 / SkylakeX overclocking saying you should try to stay below 1.2V with HCC (high core count) units, which yours of course is the king of the Skylake-X HCC dies at 18 cores.

A 360 AIO is probably "decent" for pulling heat off but may or may not be able to pull the kind of heat off you will see if you go that high with the voltage. Start slow/conservative and let the temps guide you.

Sadly the amount of quality info I've been able to find on X299 and Skylake-X series OC methods has not been as much as I'd like to have found (there was a lot more info out there about Haswell-E when I was working with X99 and a 5960X a couple/few years ago). I also have some quirks I am dealing with on my OCF board, not sure if you guys have the same problem with Adaptive Vcore mode on the Taichi's and Fataility's or not (where it ignores the Adaptive VCore voltage you give it and does what it wants to based on some scale it uses). But after reading and seeing 1-2 others posting their results/progress etc. who saw the same issue I did with Adaptive Vcore on their Asrock x299, I "saw the light" and realized negative offset is the way to keep the voltage from getting out of hand (too high) and also get the benefit of down-volting scaleback when the CPU is idle (which does not work that I have seen if you use Override mode at least not on my OCF and BIOS v1.20).

Can share some info/#'s if it helps and you want the info. Not Taichi XE or Fatality here but our boards probably have very similar capabilities and tuning settings, willing to help what little I can. Is that Fatality one of the newer generation X299's with large VRM heatsink etc?

Cheers,
PharaohsPaw

CPU Input voltage 1.39? Got mine at 1.85v. I think Level 2 in the same pciture should be good enough. If you enable xmp in the bios be sure to watch vccio and vccsa on the same page since they get a bit high with this motherboard.

Adding some numbers from my non delided 7940x at 4.4GHz allcore using a x62.

Is 1.275 VCore too much for daily use? Not gonna be running on load for more than 2-3hrs
Also, what is normal AVX limit? I set 4GHz for both.


Might want to try to overclock my RAM to 4GHz. It is samsung b die GSKill tridentz 3200 14cl
I think there is an Asrock RAM app but I am not sure if that's best, would also like settings to copy.
