2x4 gb + 1x8gb RAM

[zsedan]

Hi, I've been using 2 hyperx fury red 1866 Mhz Ram sticks, and wanted to upgrade with another 8 ( I have 4 DDMI Slots up to 32 Gb max). I wanted to buy 2x4 sticks, but instead I accidentally ordered 1x8 Gb of the same hyper x fury red stick (1866). Since I'm only buying it to be future proof is it a big problem for performance? I will probably add another 1x 8 gb to have it in dual mode in the future.

Wont notice any different doing your day to day tasks. You'll see a difference in benchmarks where bandwidth is a concern but who worries about benchmarks 😀

What you need to have is simple:

2x4GB
4x4GB
2x8GB
4x8GB

Like this you get all dual-channel performance. Now try to manage it like that.

He realises that accidentally buying the single 8GB instead of 2x 4GBs he wanted for 4x 4GBs. So now he has 2x 4GBs and 1x 8GB and hes wondering if there will be an impact on performance single vs dual channel, there wont be. Long as timings and voltages are the same, cant see why they wouldn't operate together.

Basically that was my question : ) thank you.
Right now it will remain like this (2x4 + 1x8), then I'll add another 1x8 (2x4 + 2x8)

Hm never heard of this, might try it.
I have a Gigabyte 970A-UD3P mobo, as far as I can tell, its first release was in 2011, was looking into flex technology earlier but could not find anything for my mobo.

the ud3p will run dual channel with a single 8gb & 2x4gb mate.
you may have a hard time getting it to run above 1600mhz though.

if you ever buy anoither 8gb stick then you want 12gb (a 4 & a 8gb) in each channel - as long as the channel totals are the same the board will do dual channel

That's also good to know for the future, thank you, gotta love this website : )

It is possible and likely he will see a drop in performance but a negligible one. Timings and voltages are never the same if you don't buy a kit that comes with two or four or eight. The reason is they make these in different batches and first you take the worst chips then the medium, then the best. but even in the best they aren't the same. It is kind of like making a product at one factory and moving to the other side of the factory on the other machine. They by definition can't be exact. Granted you can get very close . But if they were the same they would sell them in double or quadruples. Because usually those cost more, even though you would think they were less. The only way to fix it is what I said about flex technology for stuff like this. This way you at least get to use dual mode. If he buys another 8 in the future look on CPU-Z to see your exact RAM. I bet the codes or numbers describing the memory are not the same. But good luck

Hm when it arrives I'll check how it goes witch cpu-z, in worst case scenario I will sell it a few days later for almost the same price since it's brand new, and buy the actual 2x4 gigs.

Yeah I would do that. Or possibly wait until the price drops and get 2 8GB. But I made the same mistake you did. Since you can run it in dual mode with the 8gb in space 1 and the 4gb's in 3 and 4 its not a huge deal because it thinks there are two 8gb's. But look it up a moderator here helped me. It is called Flex technology I believe. But rule of thumb always better buying in packs.

I put it up for sale and ordered the correct 2x4 Gb kit, best option no hassle.
Thank you again for everyone's help!!!!

Yeah no problem. I should have sold mine but whatever mine is still running in dual mode and it flyes so no worries. Good luck with your buy

Arigato : )
