32gb corsair vengeance ddr4 3600MHz

Hi all, just an update, after doing some memory tests tonight I found that the reason for my instability and the problems seem to be that the ram clock speed was too fast for the mobo or just not compatible, after looking at the manufactures website the corsair vengeance 3600MHz isn't on there list of compatible memory for the ryzen 5000 series.

I have removed 2x 8gb sticks (because other users have reported problems with running 4 sticks of ram, but that will be next on my list of testing) as well as changed the clock speed to be 3000MHz, it passed memory test with no errors (previously had 44000 before it stopped the test) since then it appears to be stable without black screening and driver crashes. I will be slowly increasing the clock speeds till it becomes unstable again and then back it off.

I'm not sure if any of you will have the same issues but I thought I would raise the point so that you can check the manufacturers website to see which ram is compatible and then amend your order before it goes into building if you want to play it safe. I've also heard rumours that there will be a new BIOS driver coming out next month that may help with some of the issues.

Happy gaming all!😁

my ram starts with CM4 so the compatible versions are in the second picture

Hmm, I’ve ordered 2 x 16 gigs of 3600 RAM for mine (same mobo) don’t know whether to lower the speed by amending my order now or assuming this bios firmware will have an update...

If you can find out the model number you can check it for compatibility.

These are currently the supported Corsair 16gb.

I'm going to be keeping my set and run it at the lower speed till theres a bios update which should hopefully be in the next few months. Your set may not have any issues 🤞 , just be prepared to lower the speed in bios if you have any instability.

Hi it’s whatever PCS are going to put in my build when it gets made so I won’t know this until then?

Have you told PCS about your findings? I am assuming you're not the only one with this config... some people may not be in the position to go into the BIOS

PCS know about the AMD and 4 x 3600MHz RAM stick issue. FWIW some users have the problem with 3200MHz RAM too and workarounds lowering the RAM speed seem to work for some but not all. It's well worth the effort of investigating as @Thatthing1 has ably demonstrated. Those who aren't comfortable changing their RAM overclock might try running with just 2 RAM sticks until a solution is found.

This isn't a PCS problem, it's almost certainly an AMD problem. My guess is it's an AGESA issue - this is the extended microcode that AMD ship with the BIOS for AMD motherboards. The issue seems like some sort of timing issue across four RAM cards and it's my opinion that only AMD can fix this. If this is the case the fix will arrive as a BIOS update (with updated AGESA code) - ALWAYS check with PCS before updating your BIOS however, your warranty is at risk if you don't.
