Question Crosshair VII/5900X RAM upgrade 64GB 300CAD, advice needed

[Overhaul5589]

Hi tom's people,

I recently upgraded my CPU from the 2700 to the 5900X and I thought it would be a good time to finally upgrade my RAM from the "mere" 16GB I had.

The QVL from ASUS for this motherboard is way out of date (last update was in 2019 I believe), so I looked online for memory on sale and looked at user's comments and tips to know if it would work.

I found Kingston FURY Beast 64GB (4x16GB) 3200MHz DDR4 CL16 Desktop Memory Kit of 4 KF432C16BB1K4/64,Black on sale from Amazon Canada and some people suggested that it should work with the Crosshair VII, but it doesn't. First, memory defaults to 2400MHz, and second, the timing reading from the MB is not as advertised. The sticks should be 16-16-16-39, but I get 17-17-17-39. It's not much, but I paid for 16, and it also concerns me that they might have an issue, although memtest86 passed at out-of-the-box speed. I tried slower timing like 20-20-20-45 with 1.38v, just playing with the numbers but I get stuck at Q CODE 0d. I also updated to the latest BIOS version 4901.

Here I am looking for more sticks online and found another sale on Corsair Vengeance RGB PRO 64GB (4x16GB) DDR4 3200 Desktop Memory – Black (CMW64GX4M4E3200C16). The timing seems a bit slower at 16-20-20-38.

I'm not sure what to do. I can't find QVL for those, the QVL from ASUS is outdated, DOCP doesn't work with the Kingston sticks and their timing is wrong.

I'd like 64gb of RAM that is affordable, reliable and fast-ish (>=3200 <=C16). I have no care for RGB. My budget is around 300CAD, hence the lookout for sales.

Oh, I almost forgot (hence the edit): I use a Noctua NH-D15, so the height clearance is not as big as someone would think 😛

• Should I RMA the Kingston?
• Is this Corsair memory good?
• Any suggestion?

Hope this is an acceptable thread/topic,
Have a great time y'all

Not many folks need 64GB of ram.

You might have better luck getting things to work with a 2x16GB kit.

Oh it's still true even with the 5000 series that 2 sticks is better than four?
Nonetheless, I still need 64GB of RAM 😉

EDIT: I run many transcoding tasks (AV1) and I have some dev docker containers. I want to be able to work and transcode at the same time. Transcoding 1080p requires ~1.2GB of RAM per thread.

Let's just say that 4 sticks adds to the possible problems pot.
