Sorry guys for being less active in this thread recently, been busy with MCO stuffs (working in a pharma factory that produces medicines)...

Okay, let's get back to benching again. Here's my short OC results with the Z490 AORUS Master board (it's now on sale in LYN garage sales in case you missed it).



From my testing, the AORUS Master requires the same load vCore as the ROG Formula, at least in one loop of CB R20 benchmark. For example at 5.2/4.7GHz core/uncore all-core OC:

Maximus XII Formula:1.261v
Z490 AORUS Master: 1.265v



While I was a bit upset with the ROG Formula on RAM OC, in which I encountered inconsistent stability with 4x8GB B-die RAM at DDR4-4133 CL17-17-17 (even with auto timings), the AORUS Master however allows me to achieve stability with excellent repeatability. According to a renown overclocker that I managed to contact, Z490 board ranking in terms of ease of RAM OC would be MSI > GBT > ASUS > ASRock. There's been an issue of B-die inconsistency on Z490 especially on populated 4-DIMM slots.

4x8GB DDR4-4133 CL17-17-17 @ 1.40v:

* Ignore the wrong tFAW.

2-DIMM RAM OC on the AORUS Master is awesome as well, maxing out at 4700 CL18.
On ROG Formula, I only managed to stabilize the RAM up to 4400 17-17-17-37 @ 1.50v. Higher than that is not stable, failing TM5 almost instantly. Suspect is the wrong ODT training.

2x8GB DDR4-4400 CL17-17-17-37 @ 1.45v:


2x8GB DDR4-4500 CL18-20-20-44-2T @ 1.45v:


2x8GB DDR4-4600 CL18-22-22-42-2T @ 1.45v:


2x8GB DDR4-4700 CL18-22-22-42-2T @ 1.50v:

Wouldn't be the first time for ASUS. Perhaps it can be narrowed down to a specific memory pcb type or have you ruled that out, already?

Great testing, you've got some great dedication towards Intel if you spent your own money on this gen with couple boards.
Don't bother about tFAW anything less than x4 is subbed anyways as you surely know.

Don't know bro, maybe B-die chip itself or PCB.
Btw, my 4266 sticks are 2019+2020, same strength based on my initial testing.

I remember ASUS having issues on 2-DIMM boards with a2 pcb layout some time back.
But I kinda doubt this would happen to them across 'board' again on an entire platform.

Ye I noticed these sticks, saw one kit up for sale where you said you were going for the new 17-18-18-38 4400s Royals.
I also wanna play with one more kit before DDR5 times but Teamgroup is pretty much not approachable in Malaysia, neither directly nor though dealers.
Guess I'll have to order that one overseas, as well.

Edit, I'm not aware of ASUS having issue with 2 DIMM board with A2 PCB. I only know previous ASUS boards using T-topology DIMM layout, which favors 4 DIMM over 2 DIMM at high RAM speeds. On T-topo with 2 DIMM, you can go up to DDR4-4133 only. Higher than that says 4266 you will need 4 sticks otherwise it won't boot. Now all Z490/X570 ASUS decided to go for Daisy-chain layout, so 2x8GB 4266+ is now possible.


I have contact of Team's rep straight from Taiwan HQ, or at least I can ask local media reviewers to check out for you.
Build Tech is one of the local distros for Team.
What specific kit are you interested at?

oh nah, I should have clarified.
Boards with 2 DIMM-Slots (the old APEX line) not 4 DIMM Boards with 2 DIMM configuration.

I'll drop you a PM about the latter, thanks & appreciated!

Back to testing the Z490 Formula.

4x8GB DDR4-4133 CL17-17-17-28-2T @ 1.45v

Hmm, no idea how to tighten the subs without getting errors.

DDR4-4400 is the max I could do with 2 DIMM on this board. Most RAM timings auto btw...

Good job as always bro, first person to stabilize 4x8GB 4133C17 B-die @ 1.40v.
Nice efficiency too.

*TXP 4, PPD 0

Nice

Any reason y txp 4 and not 3??

Actually tXP does nothing with PPD at 0. Since Power Down is disabled tXP does nothing as it revolves around exiting power down. That means tXP 4 = 3 no difference. I heard with Power Down disabled, maybe we can reduce the tKCE. Ofc need to test this one to confirm. Also need to check whether these underrated settings will affect gaming frame rates or not.

TM5 needs lower VCCSA otherwise error at 13 cycles

Wow legendary OCer is here. Nice clockin' there bro.
Strong board + memory + IMC + skill

132ns, crazy.

You're attracting some big names right here cstkl & owihk

the insane dude just landed ..
bro curious what you used to cool da rams..

tested later it could run straight 17. however because i had use skews to do that.. cant reproduce. but da board definitely can "hang" with da best on voltage scaling.

Karhu likes higher VCCSA (1.35v, same as HCl)...

P95 FFT 112K forced me to reduce uncore clock down to 45 from 46 (HWI reports L0 cache error)...
