Is anyone here have experience with low-budget Z790?

I just got a cheap naked m-die capable of running around 6800MHz for daily and 7000MHz CL30-40 just for GB3 (tested on my friend's Z690 Apex).

Right now, I want move to the DDR5 platform. In my country, the cheap option is Asrock Z790 Pro $240, MSI Z790-P $280, and Asus Prime Z790-P $303.

I have good experience with Asus Z690-P D4 which is really capable board for under $250 and can run 4400MHz CL15 + very tight sub & tertiary timings for daily.

thanks!

Asrock only has support for 125w CPU, very weak VRM, half of it not cooled.

It is also the weakest for memory overclocking.

If you want a cheap one, get an Asus Prime instead, or even better look for a decent Z690 on discount.

So there is hope for my v color 🤣

On 2022 Apex it can boot/bench 7400, 7600, 7800.

It doesn't like lower clocks, booting 7200 and lower doesn't work well. I am hoping 13th gen CPU let me get it fully stable. Thanks for posting.

We tested IMC of 13700KF and 12700K

I can do 1.44-6800 meanwhile he need 1.51 for his m die + 12700K

Even ” the worst “ binned 1xx700 series have better IMC then ADL counterpart

Theres something I'm curious about for people who have reached the upper 7ks on their ram.

Has anyone tried testing if setting gear 4 allows for a higher OC, just to find out whether the limit is ram or the IMC?

And if it is the IMC, try for testing on how much further the ram OCs just to find out how capable it actually is.

Please dont buy E-Waste. Instead cheapest capable board is this = https://www.bhphotovideo.com/c/product/1728881-REG/msi_mpg_z790i_edge_wifi.html
Maybe your country going to have this in stock aswell

-12 Layer PCB
-2 DIMM
-Enough VRM and Cooling

Will thaiphoon burner show A-die or M-Die?

But okey, if they are M-Die. How high they can go as normal. Rams are in Water ofcourse.

I dont know. Try thiaphoon burner.

One way to find out if they are a die or m is see how high the boot.

M die wont boot 7600 or 7800 more than likely A die will with right settings.

For m die probably only boot 7200 to 7400 as a guess if they go higher takes a really good MB, sticks and IMC.

Also do you have 2021 Apex? If it is 2021 Apex I would test the ChA slot 1. Many are weak. If 2022 should be good. If you have weal chA that will be the limit of your mem OC. Example if you can say only run y cruncher or Karhu at 6400 or lower on chA it is weak. If it does 6800+ good.

You can disable channel B in bios instead of removing stick to test chA if you need.

But anyway if m die a good start would be 6800 to 7000 c32-44-42 and tune up or down from there.

Also new z690/z790 Asus bios has a 7600(just set freq to 6800, 7000 or 7200 to start) profile that is a good start that will load all subtimings and then you can tune from there. Profiles at the top of Extreme Tweaker page
