Dual vs Quad memory kit?

[StepDice]

I currently have 2x8 gb 2666mhz ram from Corsair rgb pro vengeance, but I want to upgrade to a 64gb kit and I can’t work out if the price benefits of 2x(16x2) kits is better than 1x(4x16gb) kit. Speeds wise I’d have to go for 3200mhz if it was a 4x16 kit since on amazon it’s £398 compared to the £850 cost of a 3600mhz kit. However a dual kit of 2x16gb ddr4 3200 is only £174 and if I got 2 of them it would be cheaper than a quad kit, what’s better? Also bear in mind the prices are from rgb kits as I plan to move my pc to my desk at some point. Thanks

You won't see any difference from dual and quad kit, as you will run them in dual channel (pairs).

You can just buy 2 dual kit, even 4 singles if it's the same module why would it be different?

If you buy 2 dual kits rather than a quad, dont be surprised if they turns out to be unstable at 3200MHz and you cant RMA in this case because they arent verified to do that in quad stick config. This will mostly be a problem for 1st and 2nd gen Ryzen, 3rd gen should do just fine

Ok cool thanks for the advice and I guess the £80 voucher on not buying a quad kit lol. Thanks

unless youre on TR there is no perf difference between dual and quad kits. Both will run in dual channel mode. Get the 2x Kit to have space for future upgrades

Ok I’m on a 3rd gen ryzen and my motherboard is dual I think.

YUP. That can do quad channel and on the 32c and 64c quad is required to get the max perf.

Also while your here, if I get 2 dual channel kits at 3600mhz it would be the same as a quad while 2 dual at 3200mhz would be much cheaper. For my build would I notice a difference between 3200 and 3600?

2 dual is not equal as a quad. Your system will still run at dual channel. Only threadripper supports quad channel.

wich CPU do you have? But even on ryzen 3 it would only be worth it for 10-20$. So yes it does impact perf but not by much.

3700x, on amazon the 3600 dual kit is £50 more, but I could check other external site. Here’s one for a lot cheaper https://www.scan.co.uk/products/32gb-2x16gb-corsair-ddr4-vengeance-rgb-pro-black-pc4-28800-3600-non-ecc-unbuff-cas-18-135v-amd-ryzen it says it’s tuned but I assume that’s just Corsair tuning

alright. 50 is NOT worth it. As I said: for 10-20 more do it. Otherwise stick with the 3200
