Computer isn't happy with XMP

Hello LTT folks,

A while ago I posted a problem that I had with a new build that I had. To cut a long story short, I eventually figured out what was causing the BSOD at start up - the XMP mode in the Bios.

Or at least I think that it is. Turned it off, didn't encounter problems for a good few weeks and only had the problem happen again when I re enabled it. Seems to be the culprit as far as I can tell.

I've checked (after double and triple checking before purchase) the manufacturer website (MSI) for compatibility and everything seems okay - the part number for the Corsair Vengence RGB pro is listed there, and so it is for the processor. There is, however, a few versions of the memory that is on there that is causing a bit of concern but I can't figure out what the version of the RAM that I have in my system is.

Put simply - what is going wrong, what's the best way to test, and how can I fix it to get the full speed of the RAM that I bought?

Thanks in advance

There is a chance that not all the memory timings are set according to profile. Check subtimings and put them manually if needed.

Thank you for the reply - by memory timings do you mean the whole 16-18-18-36 and to but it in by hand rathat than having the XMP do it automatically?

Please excuse my ignorance - Memory isn't a strong point with me, I'm afraid.

Yes.   You might also wanna check the voltage in the bios for the memory.   Depending on the board you have you may or might not have to adjust the voltage manually, but sometimes the voltage changes on its own when you set the frequency.   I've had both occurt with different Ryzen mobos.

Yes the whole 16-18 etc. But those are probably loaded correctly, so check that TRFC, TRFC2 and others are set accordingly. In my UEFI I have a page called SPD which displays all the memory timings for stock and both Extreme Memory Profiles (XMP).
