My RAM is advertised as 2400MHz DDR4, and the box it comes in says 2400MHz, but it is default clocked at 2133MHz. Every time i try to raise that to 2400MHz my PC crashes before i can even start windows. I may be doing something wrong, but in the Mobo BIOS i just change where it says DDR4-2133MHz to DDR4-2400MHz. What is strange is this RAM is also advertised to be good at overclocking, saying 'Low profile memory for high performance overclocking. All i have got is low performance underclocking. It wont even run at stock speeds. Help please.

RAM- 1x8GB Corsair Vengeance LPX 2400MHz
Mobo- Asus Prime B350M-A

Sounds like enabling XMP on an Intel motherboard's memory which unlocks the memory's full rated speed capability (I have 1866 DDR3 but if I do not enable XMP in the BIOS, it runs only at 1600). I looked over the manual under the memory section and didn't see anything for enabling some similar setting. That was my first suspicion but assumed AMD didn't requre that on Ryzen since I didn't see it (or I looked in the wrong area).

Anyway, glad you got it working. I just read up on more info for others reading this with a similar issue: AMD boards have their own name...

Have up updated the BIOS? People with version 0502 were not getting past 2133MHz. FYI some Ryzen motherboard vendors are still having "teething" issues getting their boards updated to run at higher memory speeds than the rated memory. This is especially the case for those who have faster than 2667MHz memory.

I have not tried that yet, i assumed my BIOS can't be that outdated considering it is a new Motherboard and i just got it not even a week ago. I tried to look for drivers on the Asus website but i could not find them. other posts are saying to avoid updating the drivers for your motherboard unless i am having issues with installing windows. I am not sure what to do. Is there a step i missed in the BIOS maybe. I did not do much in the settings, just changed the memory speed.

That's no guarantee of anything. You could have been sold old stock that had older BIOS. Best way to check is during bootup see what Rev the BIOS says in the ASUS splash screen.



Drivers and BIOS are two separate things. A BIOS upgrade is sometimes very necessary, depending on your issue. That's why you need to find out what BIOS you are running first. From there, if you are running one of the latest BIOSs, then you can look at memory. Where did you buy the memory (and motherboard for that matter)? There are some shady sellers out there who will re-label memory as slower than what it actually is.



He's not trying to overclock it. He's just trying to get it to run at the rated speed it is supposed to be. But yes, overclocking memory and running tighter timings can cause more problems than any gain and wreak havoc on the system. It can cause everything from BSODs to data write errors to the drives to corrupt registry files.

I got both the components from Amazon, so i assume nothing shady. How do i update the BIOS? it looks quiet tricky and i don't want to mess anything up by forgetting a step. I feel i am good enough with computers to download any updates, or reset/backup things on windows, but when it comes to the BIOS i am not so sure.; is it worth doing this or not, because i am annoyed that my RAM speeds are slower than advertised, i think it is a bit of a dick move from corsair.

Again, before anything, find out your current BIOS version. Have you done that yet?

I managed to sort it all out, i was making the mistake of not changing a setting in the BIOS (D.O.C.P or something like that) as well as just changing the clock speed.
