Mixing 2x4GB and 2x8GB?

[Flibbib]

Hi all,

 

I was certain this would work fine, but just doing some double checking and I feel the people on Tom's hardware that I've read from are 10 year olds with no clue, or maybe I am genuinely wrong.

 

I currently have Corsair Vengeance Pro 1866 2x4GB In dual channel on a Z97 board. I have just brought the EXACT same (timings, speed, brand) BUT it's a larger size, and the current ram is only a month old so possibly same batch, but it's a 16GB kit. This would mean I'd have 24GB RAM (2x4 & 2x8).

 

I was under the impression this is absolutely fine but now I'm wondering as I've read loads of people saying "no it wont work", but then again they are also saying the sweet spot for an editing / gaming PC is 8GB lol...

 

Please, just reassure me this'll be fine.

 

And be nice, I feel like a noob now after this

Just try it and see what happens is all I can say

What's the likelihood of failure? Or is it literally a 50/50 job? I've mixed and matched in low budget servers before and never had a problem

8 GB is generally plenty for any game, as far as adding DRAM, it's never a good idea to mix sets of DRAM, even with the same exact model. You have no idea if the sticks will play nice with each other, generally the chances are decent with say 1333 and even 1600 if the same model or at a minimum the same freq/timings and voltage.

This will most likely work completely fine, no need at all to worry.

^ He's right, it's totally fine to mix RAM sizes.  There's always the possibility that you'll run into an issue, but just go into it knowing that you can definitely do this.

Look up your motherboards user manual, you'll probably want to setup the sticks like 8gb sticks in the first and third dims and 4gb sticks in the 2nd and 4th.  Depends how your mobo want's them to be setup.

Ok cheers guys. I have the 4gb in dimms 2 & 4 as I used to have a 212 evo. To save me digging out the manual does anyone know what config it should be for a MSI Z97S SLI Krait board?

Honestly, it doesn't matter that much, as long as two of the same sticks are together in one channel (even then, it's not the end of the world if they aren't).

It will work just fien. DDR3 is ddr3 . Worst case scenario some boards are a bit picky about ram

Glad I did a search before posting a new thread, basically my exact question. Have a 2x 4GB Corsair kit in my '14 Haswell build, and was thinking I should buy some more RAM soon as the UK prices now of a 2x 8GB kit is basically what I paid for 8GB 2 years ago.

Guess I would just move the 4GB stick to slots 1&3, and the 8GB sticks into 2&4

 

I'm still on w7 Home though, so it would only see 16GB until I "upgrade" to w10. Have delayed doing so after having multiple issues over the various previws builds on my spare laptop (although it evened out once it hit retail). I'm happy enough with w7, but its a gaming PC so basically DX12 is influencing my decision.

So that decision has been made, but trying to decide whether I should sacrifice my w7 home full version key to something that will likely be w10 oem essentially afterwards (ie. tied to my MB), or just buy a w10 oem license and keep w7 for the laptop or another machine.
