Mixing DDR4 sticks okay?

[razer121]

Bit of an odd one but if i was to mix say these two models,
CMK16GX4M2A2666C16W
CMK16GX4M2A2666C16R

Would i see a performance hit? the reason i ask is that i want to have two red in the center and two white on the outside but obviously the way that dual channel works isnt like this XD But obviously matching the ram speeds etc in theory should be fine should it not? Or am i missing something crucial?

They are identical memory sticks so no you wouldn't notice any difference. The W and R on the end as you probably know just means white and red

not necessarily Jonj, chances are he'll be ok but corsair are known for swapping the chips or changing SR to DR without telling people. I've bought multiple twin sets off ebay and been fine, others have done the same and found incompatibility, so YMMV. I'd say give it a punt and return it if they don't play

Edit - that's if buying 2nd hand etc and time gap between. If you're ordering both sets new at the same time I would think you'll be ok tbh.

yes. I'm afraid those are corsair sticks and not crucial.

Some sticks with the same designation can be made up from different underlying chips, I don't know if that's the case with these, but probably worth checking. You can use Thaiphoon Burner (cautiously) to identify.

I have mixed many different makes and speeds over the years and have encountered the odd problem but mostly been ok. If you can buy from Amazon or somewhere with a good returns policy and if things go wrong just return a set

Noted, I'm going to order the white ones on a pun, if they don't work together I will just make do but thanks for the input guys at least I've a better understanding now!

So this is something I'm considering doing myself with the Crucial Ballistix RAM, wanting to do the same white-red-red-white layout. I think the red ones I received are single rank from some stuff I read online, so to be clear I would need the white to also be single rank? CAT-THE-FIFTH also mentioned to me in another thread that there is a chance of different dies with this ram, would that also affect mixing of the sticks?

Ideally you want all the innards to be the same for most chance of stability. The rank definitely. If you can't find out, buy see what CPU-Z and Mem-Z say (or your mobo, some have very detailed descriptions accessible via bios/uefi)

I mixed two Gskill sets on mine and it worked fine, turned out they're identical under the hood. Red and white FTW. Knowing they now match I could change the order on the board, but I can't be bothered as it's all hidden now anyway.

Aw man, I hadn't seen those ram sticks before, they look so good. On looking for them it turns out they're definitely too pricey for me though. *Sigh*

Yeah prices went crazy last year, I got those via ebay. UK stores were all OoS. The red ones camefrom Italy of all places. The combo worked out about what UK rrp was back then if anywhere had had them in stock. Turns out the reason for the shortage was GSkill launching AMD tuned LED kits. I'd have spent about the same once those launched, but well I'd already spent my budget by then. At least I got some decent BDie I guess.
