T Force RAM won't OC

Tech Support Solved

So, I've just finished building my pc, but I can't seem to get my ram to run xmp (3200). If I just enable xmp, and leave it on auto in the bios, it won't post. I get the ram debug light. I turned off xmp, and it posts just fine with ram at 2400. I tried enabling xmp and manually setting the voltage to 1.35, and it posted and has remained stable. However, I downloaded cpu-z to make sure the ram was actually running at 3200, and it appears only 1 stick is running xmp. I have tried searching Google to troubleshoot, but am struggling to find another instance like my issue. I'm hoping one of you can shed some light on the situation. I have attached screenshots with bios settings and cpu-z data. BIOS is most recent

MSI z590 pro a 11600k

Edit: After crosschecking with HWinfo64, it appears the ram is running at 1600/3200 and that CPU-Z struggles to read multiple dimm slot speeds on the SPD tab. The BIOS now reads 3200 for ram speed, as does task manager, HWinfo64, and the memory tab of CPU-Z.

1600x2=3200mhz

So as long as you manually set the timings and voltage you are good.

You're looking at the wrong CPU-Z tab. SPD shows you the default settings, but not what the RAM is currently running at. You need to look at the Memory tab.

I will check the memory tab when I get home, but spd is showing one stick different at 3200 and the others at default

What you are looking at are the various SPD settings for the RAM at various frequencies. It's coincidental that they are listing 4 different settings. What it's not listing is the settings for each DIMM.

All 4 sticks are the same brand and rating with the same timings. CPU-Z reports one stick running at 1.35v with the correct speeds, but the other 3 it claims are just running 1.20v at 2400

I will try hwinfo64 tonight. The bios setting on ram says linked, is that what you're talking about?

Also make sure dram voltage is 1.35v, it shows 1.4v in your Imgur bios screenshots.

DRAM voltage is set to 1.35v in the screenshots. CPU voltage is reporting 1.4v. I'm not sure how that pic got cut off. I'll have to retake it. CPU-Z only reports one stick getting 1.35v and running at 1600 (3200) while the others show 1.20v and 1200 (2400)
