Switched from Maximus XII hero z490 4400mhz dual rank to msi ace z490 4400 dual rank.

Same settings, latency 5ns higher.

Is msi Bios bugged?
I read now all people have the Same Problem on msi z490 with bugged way too high latency.

For example, even with 4600 c17 i have 41 ns with trained good rtls and iols

then tXP = 4
What is this talk about tXP4 giving people stutters in games? Many say that tXP 6 is better in this regard.

What limits are there to what ddr4 ram I may put in my Alienware r9 pc it came with dual 8 gb 2666mhz With 4 ram slots. I know I can’t mix them due to BIOs recognition but if I were to take out the two 8gb 2666mhz Kingston’s and switch them with dual 16gb hyper x fury @3200 would I run into any problems? It’s an code i7 9700 . (Sorry guys I’m new to pc world if this question seems ridiculous please bear with me everyone started somewhere)

Lol this ASUS Maxi Hero is soooo different in terms of BIOS compared to my MSI Z390 Ace...

Can someone give me a quick and dirty settings list for DRAM OC? I mean. It doesn't matter what I do or set or whatever, it just POST loops all the time back to safe mode.

Even simple stuff like 4000CL19 doesn't even attempt to pass POST at 1.4v SA 1.35v IO 1,6v DRAM.

I'm probably doing something simple wrong I just don't see it..

I mean, it can boot the 3600CL16 XMP profile just fine but if I even raise that to 1.55v DRAM and 3800Mhz it still doesn't even attempt to POST while my Z390 Ace will run those exact settings all day.

It might also be the CPU, I mean this is a new to me 9900KS with a different stepping compared to the P0 9900K I use in the MSI board.

I'm thinking of putting this CPU in the MSI Ace and seeing what that will do. Problem is. I'm out of Conductonaut and new order only arrives in 2 days. I'll have to settle for normal PK-3 then at first or just re-use the Conductonaut lol.

EDIT: I'm starting to suspect the CPU honestly.
Even with my 2x8GB SR B-Die kit that is known capable of 4266C16 it will not boot anything over 3600 ish on the Maximus with the 9900KS.

I will probably swap the KS into the MSI board and give that a shot with both my SR 2x8 and DR 2x16 kit but I'm really thinking this purchase was a total dud.

@itssladenlol Set PPD = 0, and if there is no such, then tXP = 4
As i said Same settings on both boards.
And txp ppd isnt 5ns Difference anyway.
Just got confirmed from msi dev via YouTube channel that msi z490 Bios is indeed latency bugged.
5-6ns slower than Asus and Gigabyte boards.
Z490 ITX Unify got fixed Bios already.
ATX boards still waiting for fix

FFT112 and cpu/cache..
higher u go the more you need.

its sharing so ppl will realize the correlation

[email protected] dats really not bad.. screenshot with prime small fft 80 30mins?? cause thats the highest clocked 10850 that decent i have seen... vmin should be 1.27-1.28.. thats pretty much sp80's cpu...

did u post a v/f of that cpu??
Thanks for sharing, I was just curious.

1.4v vcore set, vdroops to ~1.3v LLC6. Not sure if p95 is configured how you requested. I just used small preset.

What bios are you on? 0602 is on of the better one and the latest 1602 is good for me also. Don't you have 4 stick to try? That board doesn't do very good on 2x8. It should do 4000 but it can be picky depending on the sticks with 2x8. 4x8 should do 4133-4400.

If you are talking about the 2x16 then I think 3800 was all I could get stable. 4x16 worked at 3800c16 also, I did not do any long term stability test with 4x16 just quick benches.

What bios are you using? The test bios is what I have found to get the best performance.https://community.hwbot.org/topic/198450-msi-z490-meg-family-test-bios/

I have had both boards and they were pretty close in latency when both have all timings tightened up. If you leave timings on default the MSI is higher. MSI sets TXP and tXPDLL and other timings higher on default, if you lower them it can reduce latency a good 3-4ns. I have another z490 Hero coming to try the newer 2x16 Gskills as the Team 2x16 kits I have would not go past 4133.

The most recent is A.2V, released Sep 14.

All MEG series here:
Thank you I will check it out.:)

1602 is what the board came with. I switched the 9900KS into my MSI and while it did do a much higher memory overclock, it booted 4133 CL17 just fine with 2x16GB, even with a delid and direct die it ran super hot at a lower voltage and drew way way more power then my P0 9900K. That thing does 5.1 core 4.8 cache at 1.256v VR VOut at about 90-92c drawing ~260w in FMA3/AVX Prime95 as a absolute maximum OC with just a lapped IHS and Conductonaut. No delid.

The KS with a derbauer delid die mate plate and direct die Conductonaut did 5.1/4.8 @ 1.196v VR VOut but with 100c throttling and 310-320w power draw.. I could barely get 5Ghz stable with how hot that thing ran lol. And due to the fact a KS is a R0 stepping with hardware mitigation for spectre and such it actually has a LOWER IPC then a P0 so there's zero redeeming factors for the KS or the Maximus as the MSI Ace and P0 K do better in every single scenario.

Well, as soon as the FTW3 3080 is available I'll buy that and sell the KS, Maxi, and my 2080Ti as a full set paired with the 2x8GB B-Die kit and a 750w seasonic focus gold lol.

Would anyone with an Apex XII and 2x16GB B-die kit be willing to export a profile to USB and share with me? Ideally with VDIMM 1.45v and RTL,IOLS manually set would be ideal.

I'm pulling my hair out getting anything above XMP stable with the 4000CL17 Royals. Even with 1.5v VDIMM, IO and SA at 1.35v, and 18-19 primaries I'm getting errors within seconds to minutes.

Have you checked the dimm temp?

Thank you so much, i downloaded and Updated Bios, changed ppd to 0.
Right now 4500 2x16gb dual rank c18 @1,50v is running gsat.
No errors yet.
If 4500 is actually stable at 1,5v im ****ting my pants.
Didnt tune rtls or iols at all and its 36,5ns now :D.
I think with 4600 c17 and tuned rtls iols i can hit 34ns.

This msi board is the Best ive ever had.
Had maximus XII before and it would need 20 boots to train 4400 with Same sticks.
Everything over 4400 dual rank was impossible.
Msi boots 4600 with this sticks every try, i have yet to press the Reset Button or cmos clear.
It recovers from everything like a Champ and trains 4600 in a matter of 5 seconds.

Happy i didnt change to the apex, the msi even boots 4700 on this dual rank sticks lol.

Can you tell me values for txpdll and the other values?

Cause on Auto its 39 and I didnt write down Timings from Asus before..

Looks like I'll be shopping for new RAM fairly soon. Of the following, which one would be easiest for the lazy person who doesn't want to spend days tweaking their RAM? (Yet, I still want decent performance for the cost!) I also understand that bigger frequency numbers might not be as meaningful depending on latency. However, I'm clueless on tweaking RAM and would just like the best bang for the buck at XMP with perhaps minor tweaking to start... and saving the extensive tweaking for later down the road (perhaps in the winter.) No matter what, anything I set the RAM for needs to be 24/7 stable.

Motherboard/CPU is an Asus maximus 12 hero (z490) and the CPU is a i9-10850K

F4-4000C16D-32GTZR (4000 16-19-19-39 @1.4)
F4-4000C17D-32GTZRB (4000 17-18-18-38 @1.4)
F4-3600C16D-32GTZR (3600 16-16-16-36 @1.35)

Thanks
Gary

So dunno what u talking about

This going by memory so it could be off but I thought what I had in Memtweakit was

When Mode 1 set in Asus bios
tXPDLL - 29
tXP - 8
tXS_offset - 5

Mode 2
tXPDLL - 25
tXP - 7
tXS_offset - 5


Note; I could not find tXS offset in MSI bios unless by another name.

If you set PPD to Off or 0 I don't think there is as much of difference when changing the tXP settings or not that I have been able to tell.

Yeah I am impressed with the Unify. I have a z490 Apex also and it is super slow to train 2x16gb memory compared to the Unify. But once it is trained Apex boots fast. It could be my memory though as I just have the older Team 2x16 sticks, still waiting on the new 2x16 Gskill to get here.
