Well, after holding out for about 5ish years I'm fully upgrading my system from 10900k + 3080ti to a 9950x3d + Asus 5080, on an Asus x870e Crosshair Apex, 1300w MSI MEG psu. I've been looking around at OCing videos and articles. Currently in the process of buildng her and I'm taking my time enjoying it.

Had to do a lot of reasearch on Ryzen overclocking and more specifically about tuninig this 9950x3d, as well as what ram goes best and how to OC. Quite a learning curve from OCing intels.

I think I'll go the easy route on the CPU and just use PBO for a light undervolt/overclock. Any videos or suggestions for that I'd appreciate!

Now for the main question, ram. I have two kits:

-One kit I purchased from a buddy of mine: preowned T-Create expert 32gb single rank 7200 cl34. CTCWD532G7200HC34ADC01 LINK

-I do however also have a new Corsair vengeance kit 32gb 6400 cl30 single rank CMK32GXX5M2B6400Z30 link

Couple notes:

-I can't find any die info on these two sets, can someone help me identify them? Also, what would be considered the better one for OCing and for my config?

-I'm runnig a 9950x3d, on the x870e Apex board which only has 2 DIMM slots, the 7200 cl34 kit has a custom heat sink block on them direct link which is pretty heavy duty with thermal pads, a direct ram cooking fan right underneath them (included with the mobo), and a EKWB lux 360 AIO in push-pull config as an intake on the side of my o11 EVO RGB.

I'm assuming and hopinig this combo of ram and cpu, custom heatsink, drect fan cooling, and AIO config should give excellent cpu and ram OCing results. But, I'm happy to hear your opinions or recs. Thank you and apologies if this is a reapeated post!!
