[SOLVED] Mixing different RAM sizes.

[Chris David]

So, this thread is to help my friend who wanted to be different, by joining Team RED when they were still on their way of making strides, but completely forgot to take note of the things he needed to do to get a Team RED build properly working.

I'll list the specs first :

Corsair TX650M 80+ Gold Certification
ASUS Prime X-470 Prime Pro
Ryzen 7 2700X @4GHz (Wraith Prism)
G.Skill Trident Z CL16 3200MHz (1x16)
Asus AMD RX Vega 64 ROG Strix 8GB (OC Edition)

So there are the specs required for this thread.

I was skeptical of his build being weaker as opposed to the rest of our squads builds, which were more or less unbalanced than his is (bad upgrade plans). He had help from another one of our friends, basically he went against all advice's and went on to make a series of bad decisions (i.e wait a month or two for the RTX cards to drop, either wait for 3000 series or invest in a 8700K, instead of flushing the money towards a expensive keyboard ; keep it aside for a aftermarket etc.)

So, he already made a couple of mistakes:

No aftermarket for a processor that runs hot
No dual channel for a Ryzen
Not taking full advantage of his board's ram frequency limit (3600 is the max limit, he opted for 3200)
spend it on a vega 64 when there were better options


Now, he's about to pull something that I can't really wrap my head around ie not be able to confirm whether its good or bad. Since I showed him benchmarks of a 2700X that utilizes Dual Channel, he's trying to pull money together for another ram kit to utilize the dual channel capacity, except he decided he was going to invest the same stick he already has, but in 8 Gigs as opposed to his current 16 gigs. I am not really sure about the effects of this cause I never seen someone try to pull a 1x16, 1x8 for the Dual Channel and i am not even sure if the dual channel will work because of different sizes. So i assume at least a limited group of people were to try something like that, would source their opinions on this and provide benchmarks on 2x8 DC vs 1x16-1x8 DC.

tl;dr

no dual channel
wants to convert to dual channel
instead of getting a 1x16 3200 CL16 for the DC, he intends to get a 1x8 3200 CL16 for DLC
so instead of 2x16 DC, it will be 1x16 x 1x8 DC
asking if the different ram sizes would prove destructive towards the performance and ultimately ruin the DC efficiency.
would be cool if someone who tried something like that would post their opinions/results and benchmarks if possible

It will run in dual channel, but the 24 gb setup will behave more close as 16 gb in dual channel setup... it wont make much difference while gaming... although keeping in mind the rams are identical except the sizes...

Nah he wont have any issues whatsoever. It doesn't affect anything other than mixing ram sometimes doesn't always work. I.e from two different kits. But he won't see a dip in performance or an improvement at all really he will just have more RAM meaning he can run more processes in the back. If anything he will gain a slight performance to FPS because it's accessing the Dual Channel the size of ram doesn't really matter, it's his speeds, as long as he is using the same Speed and timings and latency then he will actual benefit from the Dual channeling of the board.

Edit- Tell him just to save up for another 1x16gb instead.

He's a impatient monkey, that's been his downfall from the start. But thanks tho, it was helpful.
