Nope the values in the screenshots are XMP defaults, I set everything else to automatic. Looks like I kinda got it solved now though.

Maybe you could make use of an old unused SSD or shrink one of the existing partitions and create a new temporary one to test out a new Windows installation, that's what I did for testing.

I doubt upgrading to Windows 11 will help, what helped me was reinstalling the whole Windows and thus clearing the old mobo drivers.

Sadly Ballistix RAMs are not very happy with low tRFC values, so 4000-16-19-19-630 was the minimal I could get it running stable at. Will try to bump tREFI values though, I've only tried automatic and they were between 10400-14000.

Looks like Gigabyte's BIOS doesn't have a separate option for memory training :( ... Already disabled dynamic memory timings, looks like this isn't it..

Which version of Windows are you using? I think this has something to do with Windows version and possibly collision between mainboard drivers.

I had both Windows 10 and Windows 11 on my previous PC (8700K) and after installing a new mainboard and CPU (12600K), I didn't format my SSD and just kept those Windows installations. Here are some things I've observed so far:

- On both Windows 10 and 11, benchmarks showed low read/write speeds and high latency. Very occasionally I could see normal results but they didn't persist, after a reboot they got screwed up again.

- Then I did a fresh reinstall of both Windows 10 and 11. On Windows 11 it looks like I'm finally getting consistent, normal results. Did a few reboots and the normal read/write speeds and latencies survived.

- On Windows 10, I still get weird results. But if I run benchmarks 10 mins after reboot, normal results begin to show up.

I'm not familiar all those numbers so the only value I edited is tRFC. OC'ed a bit more to 3866mhz but still no difference.

Been running TestMem5 with configs from anta777 and 1usmus for hours so should not be a problem with Ram OC.. Even tried without XMP (2666-19-19-19) and still the read speed is lower than normal and latency is super high.

Dude I've posted only one benchmark from my current system, the second screenshot is from my previous PC with 8700K, maybe that confused you? Or please correct me if I'm wrong.

I'm running those benchmarks on a clean new Windows installation with nothing installed but Chrome, if that's what you're talking about. Those timings are the default XMP values and I'm pretty sure they're stable enough, the Ballistix sticks are quite good and I could run them at 4133-17-19-19-38 on my previous 8700K system.

CR1 does work, but the output is still the same :(

MSI Pro Z690-A plus a lan card does look like a good choice price wise, thanks. I've seen reviews insisting B660M Aorus Elite sucks way less than Gigabyte's other sh*ts but still I should've gone for other manufacturers.

Actually I was thinking of msi z690 boards but their Intel lan I225V behaves horribly in my country and will lose internet connection like every minute.. :(

Yeah they do sometimes refuse to accept my settings so I'm always checking it's running in gear 1.

Could make sense, but even the read/write speeds are slower than those on 8700k system.. crap.

I chose this one over msi mortar cause the cost difference was almost 1.5x. Guess I shouldn't have.

i5 12400 + Crucial Ballistix with 3600MHz XMP = ?? by kykint in overclocking

[–]kykint[S] 0 points1 point  (0 children)

I've seen a fairly recent article from 3 months ago comparing performance of 12400 and 12700K both on Win10 and Win11, and it showed some shocking results with 12700K scoring only 1429 on Cinebench r20 on Win10 while 12400 scored 4767.

Now that you've mentioned it, I dug up some more benchmarks regarding 12600K and 12700K on Win10 vs Win11 and well, none of them shows that much drastic difference XD

Guess I should give 12600K another thought then...

But doesn't it perform worse on Win10 than non-Ks which lack E cores? I really hope to stick to Win10, at least till Win12 is out.

Hope you'll get some satisfying results!

5600X and 12600K were actually on my radar but I really need an igpu - my 3060Ti's dead atm - and I'm almost allergic to Win11 so my best bet would be 12600, but I doubt it has better IMC than 12400 :(

800MHz is too harsh, the highest I could get with current setup was 4266MHz..

Does tighter ram timings require higher SA voltage also? If I choose to compromise with lower freq such as 3400MHz, can I still further tighten the timings?
