Asus Z490 stuff

So there's a couple of timings exposed in MemTweakIt that show huge potential in regards to mem oc, tXP and PPD.

Tested in AIDA:
tXP 7 + PPD 1 (Default) = 37.4 ns
tXP 4 + PPD 1 = 36.3 ns
tXP 4 + PPD 0 = 35.0 ns

There's a thread on reddit about this showing gains for everyone who tests it. However, these timings are not exposed in the UEFI meaning you have to set them with memtweakit every single reboot - a huge pain obviously. Could we have these timings made available on a UEFI-level? Or is there another way we could make the settings stick?

Thanks

which version of memtweakit and what board?

I haven't found a working version for the M12A yet

MemTweakIt 2.02.48 works on the Apex and came on the included CD.

I tested and didn't see a difference in latency changing tXP but the PPD from 1 to 0 did reduce latency.

Hey guys,

Ive Upgraded from 7700k to 10900k and now my gpu score dropped from 30700 in firestrike to 29500.
Everything is the Same As before, i checked gpu it runs 16x
No heat issues either.
Is this to be expected cause the Ring Bus Has more latency cause of more cores?
Ive read something like that and thats why Many firestrike benchers use 7700k-8700k.

dude, THANK YOU SO MUCH!

This version is nowhere on the internet, like google gives 0 results. I already talked to Asus Customer Service and they said that there was no version of MemTweakIT for the M12A. *facepalm*

So I think for the first time in 10 years I used a CD drive, pulled the installer and uploaded it.

For everyone else with a Maximus XII Apex, a working version of MemTweakIT, 2.02.48:

No, the 10900K is not slower than a 7700K. Maybe you should reformat your C: drive and perform a clean Windows install with all the newest drivers.

Edit : One thing you can try first, is to remove all the CPU power limits in BIOS.
Edit 2 : Make sure your RAM is not running at 2133 Mhz speed in BIOS. If it does, that will ruin your performance.

Im Not talking About cpu performance, im talking About Ring Bus and PCIe performance.
My cpu performance is fine, but i have less gpu score in firestrike, cause of more Ring Bus latency i guess.
I have all Power Limits disabled and Run 5,3GHz allcore with 4200 cl15 ram

Latency with Z490/10900K is about ~2ns worse compared to Z390/9900K with the same memory settings, but that is not the cause of your problem. What is, I don't know.

Edit : **latency with AIDA64 memory test**

Do you even know what the ring bus is ? What would the ring bus have to do with GPU ?

Easy solution
1) Disable C1E and C3
2) Set ASPM Power management to disabled.
The biggest culprit of lower GPU core is C3 (sometimes C1E) being enabled. People who refuse to disable C-states because "muh yeet volts" have to deal with low GPU cores. Can't have your cake and eat it too...

And if you upgraded using the SAME windows install--reinstall windows from scratch. This stuff doesn't come free.
I've already encountered two people who had strange lag/latency issues who completely fixed it by doing a clean install of windows 10 from the ISO/media creation tool.
