I’m looking to buy TEAM GROUP 8PACK EDITION 32GB (2X16GB) DDR4 PC4-25600C14 3200MHZ or 3600C16 (which should be the same) does anyone have experience with them on z490? What it can be achieved with them, thanks?

Werent you one of the people with Same Problem as me with z490 ace bugged Bios, memory errors After Restart?

Is z490 tomahawk better now for you?
I haven't seen any issues after shutting down and restarting my computer on the tomahawk. Everything suited me. Bios 1.30
I have 2 systems:
1) Fractal Design Focus G White + Seasonic M12II-520 + Z490 Tomahawk + 10400 + TR Macho Rev. B + SSD 860 EVO 250GB + WD Blue 1TB
2) CM H500P Mesh White + Seasonic Focus+ Gold 750W + Apex XI + 9900KF + Deepcool l360v2 + 1080Ti ROG ASUS + 970EVO 250GB + 860 EVO 1TB + WD RED 3TB

I had 2 kits of the 2x16gb 3600c16 kits Team Group 8Pack Edition 32GB (2x16GB) DDR4 PC4-28800C16 3600MHz Dual Channel Kit and they are good for [email protected] in z490 Unify and Apex and 4266 in z490 Hero. They might have done 4400c16 but I didn't have them long enough to test that long. I used them in a build I did for someone else.

After that I got Gskill 3200c14 and 4266c17 2x16gb kits and they all run about the same topping for daily use at [email protected] in the Unfy and Apex

Thank you, this is just what I wanted to hear.

I think I did the impossible: 4x16 GB (64 GB total) set to 4,141 MHz and CL15, with a generic 4,000 MHz @ CL18 kit. 7.245 ns latency, almost near 5,000 MHz @ CL18 latency.
To make that work, it needs 1.6V. If I set voltage to 1.55V instead, I can only do a frequency of 4,040 MHz (still CL15). At 1.5V, the best I can do is 4,174 MHz at CL16.
When I bought the RAM, it costed me $10.13/GB, so slightly below market price of those high frequency kits. It's Micron B-die, if you are curious.

Already done various stress tests including TM5 with 1usmus' config, and passed with flying colours. Below are my timings at the moment; I'm still tweaking tRCD+tRP+tRAS.
As for why the DRAM frequency is odd, it's because I did a BCLK OC of 101.0. I'll see if I can push that further later.

I'll upload an AIDA64 benchmark when I'm done using the PC later, since I have stuff running right now and it wouldn't be accurate.
My CPU is an i7-8086k set to 51x core multiplier (AVX-1), and a cache of 47x. (With BCLK OC, add 50 MHz to both.) 1.38V Vcore, 1.23V VCCIO, 1.25V VCCSA.

Bruh Fr33thy :D A clueless wanna be that just needs to get good instead of trying to chase 0.5ns of latency.
Apparently everyone in ocnet hates this guy.

All because you need to install ODT: WR=80, Park=48, Nom=0 for both channels
Z390 MSI might need different values, as wr-80 park-120 Nom-34

Did some further tweaking. Tentative DRAM voltage of 1.63V, 4,174 MHz @ CL15, 4x16 GB (64 GB total) Micron B-die. Absolute latency of 7.187ns.
Dialed back tRCD+tRP for some IMC stability. Haven't bothered to push tREFI to max since I don't really want to chance it.

Based on my estimates, if I were to pump 1.7V into this RAM, I could probably hit 4,000 MHz @ CL14. Scaling has been practically linear so far.
But my ASUS bios gives a red colour warning, so I'm not sure if I want to pull the trigger on that. It's just a Prime and not a Maximus or anything.

Did you try to get tRFC lower? 700 is high... Try 350.
This higher tRFC is standard for Micron B-die; it's really only Samsung B-die that can push much lower. See chart below.
My PC will intermittently freeze if I attempt even 650. I could test down to 660 or so, but I don't really feel like squeezing every little bit out of it.
