With 1304 I was able to run my Samsung DDR5-6000 CL36-36-36-76 1.30V with XMP2. The only change I made was increasing the VDD and VDDQ from 1.3v to 1.35v. I couldn't get 1403 to run XMP1 or XMP2 even at 1.4v. So I'm back with 1304.

I'm back to what I had before 1304 update. XMP 2 set at 5800mhz. It seemed stable yesterday at 6000mhz but today I'm back to 5800mhz to keep it stable.

After installing 1304 bios I can finally run XMP without lowering the frequency to make it stable. I'm running F5-6000U3636E16GX2-TZ5K cl36 36 36 76 1.3v with no problems.

I found Intel ETU memory stress test works well at finding memory issues. I enabled xmp 1 and ran the MemTest86 in the bios and it passed. I then booted and ran Intel stress test and it failed. I Then set all the voltage values suggested in the RO...

I see the Apex Memory Support now has G.Skill F5-6000U3636E16GX2-TZ5K on the list. 6000 cl36 36 36 76
