32gb 3600mhz c16 vs 64gb 3600mhz c18 for 5600x

[lgcas]

Hi all,

Recently I’ve been looking at upgrading my pc’s ram from 16gb as I’m starting to limitations – mainly modded Minecraft or rendering (and loading large projects) on FL Studio where ram usage can hit 97%/use up to 12.5gb.

I’ve been looking at two Corsair kits, one is 32gb (2x16gb, 3600mhz, cl16, CMK32GX4M2D3600C16) and the other is 64gb (3600mhz, 2x32gb, cl18, CMK64GX4M2D3600C18) with the difference between them being £41/$51.82 (USD) so it is pretty tempting to go for the larger capacity (as well as the fact that it’s listed as “compatible” on Corsair’s website, the 32gb kit isn’t on any kind of QVL or list for my board).

The question is whether or not the larger kit is worth getting for the price? My main concern is the latency affecting 1% low frame rates. If not, should the timings be too strict for my cpu on the 32gb kit? I currently run 3600mhz cl16 at 16gb with no issues with XMP reaching rated speeds.

 

 

Specs, if needed:

CPU: 5600x

Motherboard: Gigabyte B550 Aorus Pro AC running latest bios (F16)

Ram: Corsair Vengeance LPX 16gb, 3600mhz, cl16 (CMK16GX4M2D3600C16)

GPU: MSI RTX 3060 Ti Gaming X Trio

 

Thanks!

You'd have to be a REALLY serious gamer to care about that, I should think the extra capacity is going to be far more important to you and you certainly will notice if you're running out of memory.

What are the secondary timings?

Are they dual rank or single rank DIMMs?

2x32 will always be dual rank in DDR4.

18-22-22-42 for the c18, 16-19-19-36 for the c16. Both dual rank.

Then i will recommend the 64GB kit.

Primary timings hardly matter if the secondaries get set to stupid values by your motherboard.
