How do I get my RAM to stop crashing at 6000MHz?

I’ve just built a new system with a 7600X3D CPU on an ASRock B850X-M motherboard. I’ve got some Corsair Vengeance 6000MHz DDR5 RAM. The BIOS shows it running at 4800MHz. I turned on XMP and increased the speed, but then I started getting crashes playing Clair Obscur, some of which reset the computer entirely. Do I need to do something else to get it to work? There’s settings for voltage - do I need to adjust those? How far do I push it?
 
You mean EXPO. Either way should be the same.
Voltage should be auto that's part of expo profile.

Maybe RAM is faulty, if it's crashing standard setting, not aggreesive etc

As far as I can tell these are the ones for AMD EXPO on that board.

My Corsair has been rock solid but I do know my bro bought the same memory for his AMD setup, with an Asus board and couldn't get the RAM stable. Sent it back and he's been happily running G.Skill now. So the 6000 OC is not a guarantee.

My RAM is CMH32GX5M2E6000Z36 so it’s on the list. I’ll check whether I need to update the BIOS and then have another dig in the settings.
 
Bear in mind that even if your memory is on the QVL, there is no guarantee your CPU will be able to support it if the speed is above the maximum supported by the CPU.


Max memory speed for that CPU is 5200MT/s if you have two sticks. Individual samples might do more, but that should be your minimum achievable with a board and memory combo thats validated for that speed or higher.

I would try the updated BIOS if there is one, and then try setting 5200MT/s with the voltage, timings etc being whatever is in the EXPO profile.

Ah, that's interesting. From what I'd read I thought 6000MHz was do-able with any recent AMD CPU, but clearly not! Is going from 4800 to 5200 likely to have much of an impact in real world terms?

Ok, yeah, taking it back to 5200 seems to have fixed it. So be it!

Yeah, not any CPU. Though, it isn't clear where the problem is, e.g. BIOS update can fix XMP/EXPO not working in some cases, as can selecting a different profile, which it would not if the CPU IMC had hit the max.

We could speculate that a 7600X3D is likely to be a low bin.

The difference when gaming would be very small, especially with a X3D CPU, since they help to mitigate the performance impact of slow RAM. You wouldn't want a non-X3D running at 4800 though.

Unfortunately not, the same thing can happen on with AM4 DDR4 with 3600MHz not being fully stable, but then work fine at 3200MHz. All these Youtube and forum builds we see, give us false hope :P

I would try 5600mhz if not already.
 
Yeah, Ive been trying 5600 since updating the BIOS the other day, and running testmem5, and it seems to be OK.
Mite be worry trying 6000mhz again but make sure it's EXPO not xmp profile, there's also manual tuning just adding a bit of voltage can help but id probably stick with 5600mhz if 6000 doesn't play nice.
 
You may find you can get it stable by slightly increasing voltage (careful with this!), or running slightly looser timings than the EXPO profile.

If 5600MTs is stable with everything else as is, I'd just stick to that though.

You've sort of done this but I would run at 5600 then run OCCT memory test for ~10 mins. Then go to 5800 and finally 6000. If you start to get errors at 6000MHz it may be a combo of the board and CPU I/O controllers unfortunately.
