Problem with XMP! Need assistance. Thank you!
Hey everyone! I'm facing some issues with XMP settings. My PC has been running for almost two years, and I only learned about XMP recently. After enabling it, my machine wouldn't post properly. I've tried updating the BIOS, drivers, Windows, even changing the RAM manually, but nothing seems to work. My RAM is supposed to run at around 3600MHz, but I'm only getting 3400MHz max. The motherboard compatibility check says it's a 1x8 with 2133 MHz default, even though my RAM is actually a 2x8 with 2666 MHz set. I ran the DRAM calculator too and got the same result. I tried removing one stick to test XMP, but it only worked once before failing again. Every time I enable XMP, I have to reset CMOS to get it to post. Eventually, I gave up and stuck with the default settings. Now I'm back to square one—I have time now and want to try again, but I'm not sure what to do next. Any tips or suggestions would be greatly appreciated!
From what I have heard, mainly on this forum, Corsair RAM can be a bit hit or miss on Ryzen. I haven't heard or seen anything about it in tech media, so take it with a grain of salt. Do you have the sticks in the proper slots? most likely the nr 2 and 4 slots relative to the CPU Are your sticks the same version number (ver.3.31)? Sometimes they switch out components like controllers and dram chips from one version to another, this may be due to availability or price. This can cause some severe headache sometimes. the 1Rx8 has nothing to do with number of sticks or channels but how many ranks. Basically its single rank memory is what it means. Why it says 2133 base clock i dont know as Corsair themselves says 2666.
Adjust SoC to 1.2v and DRAM to 1.4v manually. If it doesn’t work, enter timings and try again. Dropped to 2933 and it functioned. I used a Corsair LPX 3200 on an older Ryzen, but it needed much higher voltage. These were Samsung chips—maybe you should have used SK Hynix instead.
