Question What voltages should I use to get stable EXPO on my DDR5-6000 memory?

[nasirfoxx5]

My specs are:
- Ryzsn 5 8600G
- Gigabyte A620I AX (BIOS ver. F31b)
- TeamGroup T-Create Expert Overclocking White DDR5-6000 CL30 (the box states it's compatible with XMP AND EXPO so I assume it's good)
- Seasonic GM-550 550W PSU

When enabling EXPO profile 1 (or XMP, idk the difference between each option) in the BIOS, I get stability issues (really only noticeable with my iGPU) even when fiddling with my RAM voltages (tried SoC with 1.15V/1.105V/1.2V, VDDIO//VDD/VDDQ 1.2V/1.350V/1/370V). When I ran MemTest86 with EXPO and Auto voltages, I got 12 errors, but with EXPO off, it passed (and completely stable there). Haven't tested EXPO with my own voltages yet because I assume it'll just fail since I'm still getting stability issues.
I'm wondering what exact voltages should I set on my RAM to get the most stability? Been trying different combinations for days now. Feels annoying not being able to utilize the speeds I paid for..

The "exact voltage" is likely to vary.

Start with a voltage that is stable.

Increase the voltage in small pre-planned methodical increments.

At some voltage, as I understand your post, the system becomes unstable.

Roll back to the previous voltage. That voltage should be the "exact" voltage.

That said:

Explain more about the "speeds I paid for.."

What speeds did you pay for and what speeds are you getting?

Quantify.

And how are speeds being measured?

never assume!
is your memory on the support list? (exact model number)

So far none of the voltages I've tried (even Auto, the default) has been stable.

As for the "speeds I paid for", I paid for stable 6000Mhz, that is not what I'm getting!
Speeds are measured by the games I've been testing. They were faster on 6000, but my iGPU starts flickering a bit, so not stable obviously.

Don't think so unfortunately. The main reason I even got this kit anyway was because I saw another person with a similar kit with my mobo (the 5600Mhz equivalent)

Agree with @Zerk2012 - "never assume".

And the phrase "it's compatible with" should never be taken at face value.

You can try setting EXPO then manually change the speed to 5600.

You can try setting EXPO then manually change the speed to 5600.

After using EXPO profile 2 (which is 5600) and reducing SoC voltage to 1.1V, I got the most stability here excluding non-EXPO. With the same voltages I got 6000 to be as stable, now my only issue there is that I get reboots on some graphically intensive games.

According to WhoCrashed:

This is a nightmare! 😂

So you never tried what I said.

Apologies. You mean apply EXPO 1 and just change the memory multiplier to 56? Don’t think I completely understood that..
