thanks Im working on a spreadsheet of the subtimings for each stage MHZ. They and the main timings seem to get loser each 200mhz step up with the pro being higher bandwidth. I'm at 7600 now on 7200mhz ram just running XMP. If you go 7600 or 7800 you may have to losen timings to get there to avoid errors and this is where a sheet will help. I have not needed to touch voltage because XMP is already running 1.4 on VDD2 and VDDQ. Ram volts I dont touch as the things run hot at 1.4 in tests (its hot in Australia at moment). these A die sticks dont have good enough cooling even for XMP. I have a 140mm vadar fan on them.

I'd like to see a copy of that spreadsheet, it would make tweaking my set faster, tweaking memory timings is absurdly time consuming

Yeah, I also have a 140mm pointed right at my sticks, which does a decent job. 7600cl36 is proving to be a pain for me, and I'm right on the edge of stability - there's been a couple times where I've done 8 hours Karhu/lots of TM5 cycles, etc. but a random error will occur when retesting afterwards. I also usually do testing with a few degrees of extra heat in my case/game running in the background to simulate worst case scenarios I've seen after intensive gaming for long periods, and it's more sensitive to that than 7400.

It's behaving similarly to when I was pushing for 4400 on my b-die with my 10900k, where you think it's stable, but it can still randomly error out. Might be hitting a wall here, but I'll keep trying for a bit.

I got my G Skill 7200 kit running at XMP bumped up to 7400 so far, just had to manually set some voltages, on my z790 Aorus Master

I plan to do the same unless the 7600 kits get significantly cheaper in a month.

Ran Karhu for a long ass time with these new voltages for 7600cl36, also did TM5 for 9 cycles. Seems stable, but I'm going to keep testing.

VCCSA: Auto*
VDDQ CPU: 1.40
VDD2 CPU: 1.47
VDDQ: 1.41
VDD: 1.48

Seems like there's a lot of fluctuation going on with the voltages looking at HWinfo, but I guess that's normal. tRAS could also be lowered, but I'm not messing with anything else right now.



*Edit: For whatever reason I seem to run into errors when setting VCCSA manually. I did the long Karhu test at Auto, then changed it to 1.25 for the TM5 tests considering it was at that most of the time anyway, and got an error in two Absolut tests back to back later that day. Switched to Auto again, and haven't had an error since after a few hours. Will edit if anything changes, but things are being very finicky at 7600.

*Still stable so far with the original settings:

Just build this computer with TEAMFORCE DDR5 7800: FF3D532G7800HC38DDC01; I just realized that this serial is not QVL on Gigabyte

When I loaded for the first time the XMP on F4 bios that came out of the box, the PC didn't boot... 😨 ugh! Then I gave it a chance by updating to F6c and It booted with XMP but when I run TM5, I get a bunch of errors. What is interesting is that I can boot also at 8000Mhz and 8200Mhz, I haven't tried more

Now I did reduce the speed to 7600 MHZ and get the timings to match their 7600 36-46-46-84 @ 1.4 with everything else in auto (VCCSA, VDDQ, etc.) and I get no error at all stable!



The last time I did OC a ram was on my DDR4 on 5950x now with this DDR5 no matter what voltage I do, I get at the end between 1 to 13 errors at 7800, it's driving me crazy!

I also have this one coming on the way: F5-7800J3646H16GX2-TZ5RS

Anyone, to give me some advise on how I should step things, where to look, and how to properly OC DDR5? ☹

Received the G.SKILL DDR5 7800: F5-7800J3646H16GX2-TZ5RS and XMP wise it works at 7800 like the TEAMFORCE but still gets errors but it last 15 min longer before an error arises! It's getting on my nerves!

Based on the price compared to 7600 and 7800, should I keep what I got and reduce the speed to 7600 or return and get one who works XMP straight of the box at 7600?

What are the temps like when it errors out? This ram gets hot.

Errors usually happen 45 degrees and above. Get a 140mm fan on them

I have an aesthetic setup having a big fan in the middle will make it weird!

I think I'll put my ego to the side and get something slower and running less hot 7600 or even 7200 and get a bit of money back!

At this point I just want to run something XMP, Bim Bam Boom Done!

Hi folks! I have a quick question...what settings in the BIOS (UEFI) need to be modified to allow me to set manual timings for memory? This seems like a rudimentary question, but so far I have been unable to set any manual memory timings on my motherboard, regardless of XMP being enabled or not. I am able to input them into timings section of the interface, and they appear to save, but the board always reverts back to XMP timings even with XMP disabled. What am I missing?

Note that I have the Z790 Xtreme board, not Master, but I haven't seen any threads on here with the Xtreme board so I thought I'd ask here with an expectation that the BIOS layout is basically the same. I did notice that the change log for the boards is basically identical. Any help is appreciated.

Advanced Memory Settings -> Memory channels Timing.
Here you can set the timings for your RAM. Select a timing, Press Enter, then select the new timing.
You can select XMP and then modify your timings from there. XMP already has higher voltages for RAM, VCCSA, VDDQ CPU and VDD2 CPU as well as the Voltage for the RAM itself.
By adjusting the main timings you can easily go up a few hundred MHZ in memory speed without needing to change any voltage from XMP.

That's the crazy part - this doesn't work! I have done exactly what you stated on my board, and every single time, the timings stay the same. If I go into the BIOS, it says that the timings are set to the values I specified (for example CAS 32, CR 1, etc.) and yet they are never actually applied. Does this actually work properly on the Master?
