Memory Help

[JJohn429]

Hello all, 

 

I just noticed my Ram had stopped running at its full speed, here's a brief rundown of the system

 

i7-12700k

MSI z690-A

32gb 2x16 Corsair vengence RGB PRO 3600MHZ

 

Weird thing is the PC has been running at 3600mhz since i put it together over a year ago.

 

I went to re-enable XMP and it keeps booting with a Memory OC failed, 

I've tried MSI memory try it, and no matter what i do, it keeps memory oc failed, and defaults back to 2133MHZ.

 

Any assistance would be greatly appreciated

Try entering in the following settings:

1. Memory frequency: 3200 (this will be changed later) 
2. Memory Gear (this might be called something like IMC:Memory ratio): Gear 1 (1:1)
3. Timings (in order tCL-tRCD-tRP-tRAS): 18-22-22-42
4. Set 2T command rate. 
5. DRAM Voltage: 1.35V
6. System Agent: 1.4V
7. CPU VDDQ: 1.35V

Try to make sure that boots up. Once it does, walk up the frequency slowly, 1 ratio at a time, to make sure that 3600 works. 

 

All that is assuming you've got a 3600 CL18 kit. If it's a CL16 kit, enter those timings instead.

Hey so i was able to find every setting except the system agent, when i changed the rest it booted, but the issue is it wont let me just select the frequency and there is multiple options, i attached a picture. Thanks for your help, feels like progress, the 2nd photo is for reference with XMP enabled by mistake

Try the 3600 G1 (36 x 1.00 x 100) first. G1 = Gear 1.

If that doesn't work, the next one would be 3600 G1 (27 x 1.33 x 100).

 

The 1.33 variant should be easier to run, lower multiplier = lower ratio = easier for the Integrated Memory Controller (IMC).

 

I just found this...

I tried all the variations an still no dice, weirdest thing is that it used to work just fine with XMP profile, and i just noticed today that its not working.  Let me know if you think of everything else, thanks for your help man, i really appreciate it.
