Long story short I bought a new PC the other day it's been running fine but after messing around with benchmarks I know it's my RAM was running at a lower frequency than said on the box. After a quick Google I found out that I needed to enable xmp for it to reach the advertised clock speed. like an excited child I proceeded to enable it on my BIOS only to be greeted by:

So I reloaded my bios and turned XMP back off it to show that same error message.

I have:

CORSAIR Vengeance RGB Pro 16GB CMW16GX4M2C3200C16

AMD RYZEN 7 3700X

Gigabyte X570 AORUS ELITE.

Gtx 980

I did some more digging on the internet and found that motherboards and processors have compatibility issues. my motherboard appears to be compatible with my RAM but the AMD ryzen seems to have very little compatibility in the ram it likes.

Where is the best place to try troubleshooting? As you can tell I'm not an expert . Please help

Edit: I'm going to run memtest in the morning when I can get access to a working pc

Thanks for the reply.

So it turns out my windows had just died because I had another boot drive from my old pc in ready to bd and It booted windows and ran fine. So I've tried xmp again and it works. With no issue. Kinda annoying as it took me over 4 hours to run memtest .

My new question. Should be easy.

Why does cpu-z say my frequency is so low? If so how do I do it?

Thanks

At least you have the satisfaction of knowing that your RAM passed four hours of Memtest.

There is nothing wrong with your RAM frequency, your RAM is DDR (Double Data Rate) - it's just the way CPU-Z works - it shows the true frequency, you have to double that figure to get the effective frequency: 1596.8 x 2 = 3193.6 = 3200 near as can be :D

I've also got 3200 RAM and CPU-Z reports mine as 1599.6 MHz
 
Makes a lot of sense. Thanks buddy. Glad to say it's 100% working. Any idea why my other copy of Windows just stopped working? It's was on a nvme drive. The drive seems to function fine as I can read and write to it but I can't boot windows on it. Just get the blue screen? As I don't wanna have to format that drive and start again as I've got games installed already

Cheers

What are the boot order settings in the BIOS set to?

ahci mode maybe?

I don't think I can change it. Searched my bios can't find the option to change it.

1 is the new drive that bluescreens and 3 is the one that works. I change them as I need so there is no set order

Make sure ur in adv mode then go to settings, sata config then sata mode and is the mode showing ahci if so try it off incase ur last windows install wasnt installed with it on in bios before. After you get to windows you can enable ahci in the registry then u can switch it back in bios to ahci mode. Or if its not showing ahci try setting it to ahci then save and quit.

Try putting "Windows Boot Manager" as Boot Option #1.

I did a lot of digging on Ahci and found out loads of useful info but as far as i can see everything was good. I decided to Just reinstall windows on the drive which got it going again!!

OK so i said i had no issues still but thats not true as I'm getting a lot of bluescreens which I'm struggling to make any sense of. I'm hoping you smart people can help me.

So i also found my ram isnt on the QVL for my motherboard. Can this cause the issue? I mean it sounds like a big problem if they are not compatible? see attached link. My ram is CORSAIR Vengeance RGB Pro 16GB (2 x 8GB) 288-Pin DDR4 DRAM DDR4 3200 (PC4 25600) Desktop Memory Model CMW16GX4M2C3200C16

So ive attached some images below to give an example of what im getting.

But i would suggest you do this too.

https://answers.microsoft.com/en-us...em-files/bc609315-da1f-4775-812c-695b60477a93

Follow that if you can get in windows if you cant try pressing like mad f10 or one of the others to try to get it to boot to safe mode then try it.

Then go to device manager and check if any hardware is needing a driver update like in the first link.

https://www.alphr.com/microsoft/100...is, then you,computer if it's under warranty.

Also worth a read.

Also try different slots of ur ram maybe and check there seated properly. Also take photos of ram settings in bios so we can see if any setting is messed up.

  • Enable XMP

  • Set DRAM voltage manually to 1.35V

  • Set RAM multiplier to 32x

  • Set the first five subtimings manually to 16-18-18-18-36 (the same as XMP would) (important!)

  • Set the sixth timing (tRC) to 56 instead of 54 as XMP would (important!)

try that

You might also have to switch the memory slots on mb as in link suggests tho that person said he had a diff mb possible not the elite version. So unsure as to if it will help but if above doesnt, maybe worth a try i guess.

Moved mine to the first slot closest to the CPU and the third. Been working perfectly since.

Seems the mb mucks up the xmp profile so need to do it manually.
Hopefully thats the fixes. Gluck.

Now if you do that, go grab cpu-z and post pics of ur ram timings etc and well see if they check out. You could do this before you try fixing it and if you can get in windows and this would varify that the timings are messed up causing the crashing.

Also theres a few bios versions saying mem compatibility improvements, if your on a old bios try updating it to latest, then see if you need fixes, then apply fixes above then probs sorted.

Tho you bought it recently so ud think it would be on the latest bios, unless its used pc you bought?

If all you do is the timings fix and pc works id still suggest you reinstall ur gfx and sound drivers fresh, and do the sfc thing so windows can fix anything else.

Do we know if this fix resolves it for 64GB setup utilising all 4 slots? I had this issue before but my subtimings aren't working with 4 slots of 16GB per slot.

Any help is greatly appreciated!
