I recently switched out some hardware in my PC, i went from AM4 X570 to an AM5 X670E ProArt motherboard. When selecting RAM i made sure to pick up a kit from the supported vendor list so that I wouldn’t run into any issues.
But turn out that I did end up running into an issue. The kit i bought was the G.SKILL F5-6000J3038F16GX2-TZ5NR which is a 32GB kit in 2X16GB configuration. They are rated for 6000MHz, but using the EXPO1 profile the BIOS posts to safe mode. I dropped them a step down to 5800 which passed fine.
But as I am new to AM5, are there any settings or anything i can do to push the last performance out of these memory sticks?. Because I have to admit that it feels pretty bad not being able to run them at their full speed. Never ran into this issue on AM3 or 4.
I would try some different ram, I had a Gskill 2x32GB DDR5 CL30 6000mhz kit that ran just fine at 6000Mhz on that exact motherboard. Or try again after updating the BIOS.
Update to the latest non-beta BIOS, then try the EXPO2 profile which specifies more subtimings and is less reliant on memory training. Also try testing each stick individually and swapping slots.
I updated to the latest BIOS a few days ago. I have not yet tried the EXPO2 setting as I just read a bunch of people saying to stick with EXPO1 for some reason or another.
The reading in the BIOS is a bit higher than the actual setting (to account for the voltage drop between the regulator and the chip). You could try bumping it to 1.275 or so, and perhaps vdd & vddq (mem voltage) to 1.4 (should be up from 1.35 if I found the correct GSkill kit). Up to 1.3 VSOC is deemed safe by AMD, 1.4 for the memory should be safe too (plenty of kits have 1.4V profiles).
VSOC might help if the CPU is the issue, VDD(Q) if it’s the memory…
I actually have the same 32 Gb set memory and motherboard and that combo gives me a headache even at stock speed “4800” the weirdest things happen
Several older games no longer start and hang till the next age if i do not kill the power.
I updated constant to the latest bios versions and nothing solved the issue.
Now to me it is clear that they used other chips on these memory sticks than the ones tested when they got accepted as safe to run on this mobo.
I bet the price drop of these sticks tells enough also, i paid too much and can not get it to run stable at all.
As i detect constant weird problems as files gets garbled as well on my disks at random each time when i do a system check of the windows files i get some corrupte files reports and they get replaced again and again
I have contacted the shop several times but no answer from them either.
They tested it but when i checked what they did, i found that they only ran memtest86 which does not reveal the true problem(s) at all.
Wow that’s pretty crazy. I managed briefly to get the 6000MHz profile working by toggling the BIOS setting that would feed more power to the memory, by default that toggle is AUTO but set it to Enabled.
Rebooted and the BIOS did it’s memory training which passed and booted into Windows 11. I checked with CPU-Z that the speed was right, and it was. So I thought that I had finally done it. But next day i powered my machine on it did another memory training and this time it did not pass. So i yet again had to bump it down a notch to 5800MHz.
If you mean the “High DRAM Voltage Mode”, that option does exactly nothing except for unlocking the possibility for setting higher voltages cf. manual.
High DRAM Voltage Mode
If disabled, the upper range for DRAM Voltage will be 1.435V. If enabled, the upper range
will be 2.070V. If enabled on non-supported DRAM, the voltage will be lower than requested.
Configuration options: [Auto] [Disabled] [Enabled]
Possibly the voltage is rounded differently and that made a difference, or you got lucky with training? I believe DDR5 voltage control goes in steps of 0.015V in normal mode but larger steps in high voltage mode.
That was the setting, yes. I guess that it was just lucky passing that first memory training check. Because it certainly did not pass the next time i booted my machine up.
So I was a bit weary doing this, as when it comes to voltages I am out of my element. But decided to just try it out, and so far its passed boot and I am typing this on the machine.
So hopefully it will be stable and actually keep the setting when i power off and turn it on tomorrow.
