Should I get Four or Two Sticks of RAM?

[Dwight Hut Pizza]

I'm currently working on making a new build on PCPartPicker and was was wondering if it is better to have four or two sticks of RAM. I'm aiming to have 32 GB of RAM in this new build so it would either be 4x8 or 2x16.

Here is my build if you want to take a look: https://pcpartpicker.com/user/TJster/saved/#view=MWP28d

Die Density/Count just says 16 Gb / 1 die

the part number is K4AAG085W?-BCTD

Die Density/Count is where it should be listed. Might be something even even less common then.

Ok its fine then. Really it is irrelevant. Sometime down the line I will buy another set and try it our but until then my current ram works fine.

Looks like A-Die with a possibilty of M. Those aren't used much.

Yea so M-Die? or A-Die like you said. But they seemed convinced on overclock that it was M-Die. So is that good you think?

Not sure, it looks like where the "?" is would be the identifier. If A the Tom's thread has some info.

The only 16Gbit chips I really know a lot about are Microns.

Greater strain on the CPU's IMC and the motherboard's PMIC

It'll usually require more voltage for 4 DIMMs vs 2

So if an XMP profile on 2 DIMMs requires 1.45V, you're going to have to expect to need closer to 1.5V or more for all 4 DIMMs to run that same spec

The ram is GSkill trident 3600 Mhz CL18 and it runs at 1.35V. I have 32GB, 2 x 16GB, on a Gigabyte Z590 Aorus Elite AX, with 10700K. Right now, I have no issues with the ram running in XMP whatsoever. If I bought the exact same set, for 64GB, you think I would have an issue running XMP?

It will be slightly worse but probably not noticeable. You'll have four ranks in each channel that way. The optimal setting is two ranks in each channel. That's why you go with 8gb single rank dimms for a total of 32gb with dual ranks in each memory channel.

I haven't seen single rank 16gb dimm which is what you would want for your two ranks. Maybe they make them idk.

Here's my i5-11400f with 32gb (8gbx4 dimm). It puts out a sick benchmark with this ram configuration:

I'm using single ranks, four of them for dual ranks in each channel.

quad channel and dual channel are neck in neck for gaming performance (not to mention you need a board that supports quad channel) so i would get two sticks of higher capacity ram. so you have expansion space later on. the board you have doesn't support quad channel regardless,there's no reason to get 4x8gb sticks all you're doing is gimping yourself later with expansion.

That's actually not what four and two means. I'm running four dimms but still in dual-channel. Quad-channel is something different and only on hedt configurations. It's not what this discussion is about.

This discussion is about dual-channel four vs two. With this configuration four is better.

then why would it be better that he gets 4 sticks if hes not wanting quad channel?
what... hes just gimping upgrade-ability later on.
how is 4 sticks in dual channel with smaller capacity a better option?


also you really didn't read my post all the way.

My 16GB Dimms are single rank. That was what we were talking about in the previous posts. CPU-Z and Thaiphoon Burner has them listed as single rank dimms. They are fairly new. I bought them in August, but yeah, they are listed as single rank.

I haven't had a single issue getting a motherboard with four RAM slots to run four modules of RAM. Do people think half the RAM slots are non-functional, or extra risky to use, or something? From a range of stock OEM (Dell & HP) motherboards to a number of aftermarket third party motherboards, from each of the DDR (DDR through DDR4) generations, I've never had one give me a fuss with four modules. I've even done overclocking on some (a DDR2 platform, namely).

As others have mentioned, if you're looking to seriously push RAM as far as it will go, four RAM modules may reach a limit before two, but if a board has four RAM slots, it's not like it's only good to work with two.

I'm taking about reliability, not performance.

So was I? I said "I haven't had a single issue getting a motherboard with four RAM slots to run four modules of RAM".

I'm not sure how else to clarify.

You initially said "There is not many motherboard can take two different two-channel well."

I responded and said "I haven't had a single issue getting a motherboard with four RAM slots to run four modules of RAM".

You responded back and said "I'm taking about reliability, not performance."

I responded to that and said "So was I".

Or to summarize, you stated that not many dual channel boards do four modules of RAM well. I challenged that and stated that I haven't had an issue across half a dozen, which range from a few basic OEM (Dell and HP) boards up to mid-high or higher end ones (depending on how you consider an Asus Maximus Formula, P8Z68-V Pro, and ROG Stric B550-F), and from all the DDR generations (besides the newest). The one difference is that you'll get less of a performance ceiling with more modules, but this isn't really an issue if you're just setting XMP profiles with not-pushing-for-the-moon speeds, and your follow-up signifies you weren't talking about that sort of case anyway but rather just getting it to run reliably.

I, and many others, use four modules of RAM on dual channel boards quite reliably, so your initial claim isn't true. The extra RAM slots aren't just decoration, you know. They work.
