ROG G752VS(KBL)-GC310T RAM upgrade questions

So this seems like it should be a straightforward affair, you look up the specs, you upgrade the ram, presto, done. However not so. In typical ASUS fashion the model numbers are so confusing even Tech Support can't seem to get it right.

The problem:

I want to upgrade my ram. I want to have 64 GBs for video editing. That's what I want. So I went to the crucial site and there I selected rog g752VSK and it gave me an upgrade option for Dual Rank 32 GB (16GB x 2) RAM.

Cool.

But I remember a while ago that Asus Tech support told me this PC can only take Single Rank RAM.

I want to clarify it, so I go to tech support chat, we exchange info and the tech support guy tells me I have a G752VS... that is untrue. Mi motherboard literally identifies itself as a G75VSK (see image below)

Not to mention I have an i7 7700HQ, whereas the usual G752VS has an i7 6700HQ.

Seeing this is going nowhere, I accept his offer to give me compatible ram sticks and leave.

TL;DR Do I go for Dual Rank RAM or Single Rank RAM? Also should I look for better timings or just not bother at all with timings?

You do have a VSK motherboard but not the G752VS OC Edition (This is  normally reffered to as the G752VSK model). Your model is reffered to as the G752VS (7th Gen Intel Core) model. This is a screw-up by ASUS labelling simular models differently.

First: You had loaded the wrong BIOS for your model. You should have loaded the 304 BIOS not the 305. I dont know wether you can correct that or not but I'm telling you up front.

Second: You have the 7700HQ processor and require DDR4-2400 timed RAM. If you had the G752VSK OC Edition you would have the 7820HK processor and use DDR4-2800 timed RAM.

If you intend to utilize all four RAM slots with 16G RAM sticks then yes you should look for Dual Rank RAM.

I wouldn't bother trying to improve your timings with better RAM.

In case you are wondering where I get all thia information, I have owned my ASUS G752VS OC Edtion laptop since 2017 and its still functioning well.

If you have any further questions please feel free to PM me.

Good Luck

******, hopefully I can downgrade then.

Just out of curiosity, how much of a difference will Dual Rank make compared to Single Rank?

Dual Rank Advantage

One memory bank can be accessed by the CPU, while the other can undergo a refresh cycle (readying itself to be accessed).

This process, called Rank Interleaving, is similar to SDRAM Bank Interleaving.

The masking and pipelining of refresh cycles usually results in better performance for CPU-intensive applications, as it reduces memory response times.

Single Rank Advantage

There are certain applications that may be affected by the latency caused by having the memory controller run through multiple ranks instead of just one.

Also, because Single Rank (SR) DIMMs have half as many chips, they produce less heat and can be more stable than Dual Rank (DR) modules. This is also what makes them a popular choice for overclocking enthusiasts.

Dual Rank would be benifical to video editing.

Should go without saying but it's good to be careful: You've used dual rank on your own G752VSK? It works without a hitch?

Also worth asking because why not: Dual rank better for gaming or about the same?
