[wgizmo]

Hi,

I do have CMK32GX4M2B3200C16 and cant set it up for 3200. They are running at 2133 no matter what settings I made in BIOS.

Any help would be grate.

Greetings,
Is this RAM listed on the QVL for your board?

Also, if you could supply your systems specs...  CPU model, BIOS revision, etc.

Found solution to my problem. Putted my ram to A2 and B2 slots and in BIOS I did chose Profile 1 and rebooted. All works fine. In A1 and B1 sockets ram didn't work on 3200.

Yes.  Page 10 of your manual states install in A2 _ B2 for 2 DIMM configs:

Due to CPU limitations, read the following guidelines before installing the memory in Dual Channel mode.
1.
Dual Channel mode cannot be enabled if only one memory module is installed.
2.
When enabling Dual Channel mode with two or four memory modules, it is recommended that memory of the same capacity, brand, speed, and chips be used. For optimum performance, when enabling Dual Channel mode with two memory modules, we recommend that you install them in the DDR4_A2 and DDR4_B2 sockets.

OK after some time of using it I notice when the yare on XMP profile they crash my pc in situations when i play some games like wow, gears tactic. When i leave them on default in bios none of the games crash my pc. Its hard to get any of the ram from the list as most of this ram is discontinued. Any help and advice would be good.

Yes they are on the list, doing testing with some settings from other forum:

"The following settings solved his issue:
- 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!"

No success with the ram in any configurations.

Greetings,
I would suggest disabling XMP and setting your voltage, timings multiplier manually.  1.35v, 16-18-18-36, etc.

The CPU is supported from BIOS F3.  Did the memory work with an earlier version?  F12e is Beta.  I usually recommend avoiding these.

What you really need to check is the revision number.

Corsair use the same "part number" across a whole range of sticks and the only way to know exactly which you have is to check what revision number they are.

The revision number helps identify which brand of memory chips they are using as corsair use various brands presumably according to the spec and cost etc.

Some of the revision numbers on that particular model are flat out are incompatible with Ryzen and no matter what you do you will not be able to obtain 3200mhz using the XMP profile. Weirdly it seems to be a production run in the middle - the early ones are fine and the later versions work no problem.

They will run fine at stock JDEC settings, which is something like 2666mhz i think.

I got rid of mine so can't recall exactly which revision I had - i want to say 5.39......?

I had a tonne of problems with that exact same "model" - on the face of it they are great C16 3200mhz. Initially they only ran at 2966, after a couple bios updates they ran perfect at 3000mhz then following later bios and agesa revisions they got borked again to 2966mhz.

You could try using these two utlities;
Thaiphoon Burner
DRAM Calculator for Ryzen v1.7.3

Its due to this exact issue I now don't buy Corsair RAM anymore.
