above 6200 it’s problematic to take 1: 1 for now I’m just checking what and how can be done
understood. I also cant run over 6200 in 1:1 on my 7900x. I just wanted to make sure that you knew that the high latency was mainly attributed to 1:2 mode and not cmd rate/gdm/powerdown.

At 6400, no matter your timings, youre not going to make up the latency penalty. Since youre committing to testing configs in 1:2, you should really focus your efforts on getting your system to boot at higher mem frequencies instead of trying to tighten timings at this point in time.
 
@Veii
tell me if there are any recommendations to increase the performance of memory above the speed, they fall very much, I can’t turn off cmd and powerdown, because of this the latency is high, what can be replayed by timings? voltage above 1.4 do not want to bully

Whoever you followed
primaries are messy :)
VDD to VDDQ is messy
SDs are odd
REFI is small
Rectangle Font Material property Pattern Temperature

RFC is a random value
If you want to use 500 instead of 512
REFI needs to be different

Lets start small
First fix REFI to 24575 and RFC to 512 ~ should result in no change // give a report to have something to compare to
Then decrease RP to 36
If you see any change, any positive change - be it here or pyprime
Then you do row-miss (way to low value) and RP is inserted as emergency correction while RAS is halted.

Please quote back with a result and we'll continue later~
 
What's the best kits 7200/7600/8000 you should advise to take benefits of these new bioses ?
I am looking for 32GB (2x16GB).
 
CROSSHAIR GENE 1514 - managed to boot 7400 MT/s (2x24 Hynix 8000 bin), above that - no luck yet
But there is something weird going on with VDDIO - setting it manually never posts ("00" post code), leaving it on auto - always defaults to 1.1V
Also setting VDD/VDDQ only worked for me via "AMD Overclocking", setting it via "Extreme Tweaker" doesn't post (probably because it adjusts VDDIO with auto rules)
So the 7400 MT/s I mentioned booted with VDDP > VDDIO (1.1779V / 1.1V) which is weird. Maybe this is a reading error?
Anyone else experiencing this problem?
FInally managed to boot 8000 with my 2x16 Hynix A-die (7800 bin)
The solution was to apply XMP timings, with full-auto timings max bootable was 7400

VDDIO = 1.1778V (still cannot boot anything above 1.2V)
VDDP = 1.0774V

Now going to try my 2x24 and 2x48 Hynix kits and then decide which one to tune further first

The TeamGroup 7800/8000/8200 are really binned well and pretty cheap.

My 7800 does 6400 CL26 and should easily hit 8000 with decent timings.

Dude, I would just get the highest bin you can afford, more flexibility when this platform improves, think of it as future proofing. There are quite a few high bin 2x16GB kits available at good prices. Im finding it easier to reach high frequencies with higher bin kits.

I saw a person from the forum have the same kit as I have for 64 times I have to put up with 1: 2 I decided to try a voltage of 1.45 lower, it doesn’t start higher, I also tried the system is not stable bsod, but I don’t like some parameters, what can I see here?
 
Does this translate into actual performance gains in usable games and applications? Several pages discussing it. Zero usable results.

Did you test from your side ?
That's the best way ;)

the memory does not take higher than 6800 under any conditions, what is the voltage, what timings, if my whale can no longer be changed, unfortunately, I think because of the volume of 64GB

That’s good.
Are you stable at 6800 ?

mine is even not stable (errors in Kharu’s) at 6600/2167 1:2 cl30 ( my kit is in sig), but is fully stable 6400/2133c 1:1 cl28.
At 6800, I Bsod.

‘I think my kit is bad binned . Hopefully my IMC is really good.

Yes, the system is completely stable, I got some increase in my tasks, I’ll try to play around with timings, but I don’t think that it will be possible to improve the result
you included these settings in the menu, because at first I also didn’t start above 6400 stable

Yes, let's wait for more mature bios.
Also, expo kits 8000 in next future ? :)

BIOS 1512/1514/1515 has decimated my 2x48GB stability on the Gene. Can't even boot XMP-5600 anymore, just instantly restarting when booting into anything, even Windows Automatic Repair.

Only completely stock 4800MHz doesn't crash instantly. I tried enabling Nitro + Robust training, didn't help.

Exactly, I found that going over 6000mhz with really nice tight timings and 1:1 clock ratios is lower latency (more important in real world apps and games). Doing 6400mhz with looser timings and clock, fsb ratios gives worse latency but a little better bandwith (which you don't need unless maybe rendering 24/7). I don't see the appeal of slightly higher frequencies with a lot higher timings. Makes no sense. Same thing with these 14gb/s new Gen 5 NVME SSDs, yeah they are faster for people loading terabytes of data all day long for video editing or something, but they are actually SLOWER in real life for windows responsiveness and games, why? Because their random read and writes are actually worse than say a WDSNX850 or Samsung 990 pro gen 4 drive. We DON'T need bandwith, we need lower latency and lower random read/writes.
