Max RAM for System

Hey guys,

I'm looking to upgrade my RAM to 64gb and I'm worried my motherboard won't be able to support 2x32. I've been unable to find any resources online as to whether or not my mobo/cpu will support 2x32gb DIMMs. I'd prefer not getting 4x16 since it costs more, so I'm wondering if anyone here has any idea. Thanks

Relevant specs:
r7 2700x
Asus PRIME X470-PRO

Irrelevant specs found in my profile.

 

EDIT:

I know my mobo supports 64gb. I'm asking if I'll be able to use two sticks of 32gb ram or do I have to use four sticks of 16gb ram.

Looks like max 64gb for you.  (located from your motherboard's user manual: https://dlcdnets.asus.com/pub/ASUS/mb/SocketAM4/PRIME_X470-PRO/E13883_PRIME__X470-PRO_UM_WEB.pdf)

Huh, maybe I wasn't clear enough with my question.

I'm asking if my mobo/cpu combo will support 2x32gb DIMMS or am I limited to 4x16gb DIMMs

Thanks fam. Do you mind linking me to where you found that?

 

EDIT:

nvm I found it in the manual

Even though the manual says 64gb, I bet you can still use 32gb sticks from corsair or the likes in order to have a total of 128gb of ram.

FX6300 @ 4.2GHz | Gigabyte GA-78LMT-USB3 R2 | Hyper 212x | 3x 8GB + 1x 4GB @ 1600MHz | Gigabyte 2060 Super | Corsair CX650M | LG 43UK6520PSA
ASUS X550LN | i5 4210u | 12GB
Lenovo N23 Yoga

That's the thing, this motherboard was released when there weren't >16gb sticks available. While saying going above 64gb is a stretch (the cpu wouldn't support it), I'm willing to bet that 2x32gb or even 1x64gb would be recognized.

The 2700x does support more than 64gb of RAM. See here (it's even running on a b350).

 

I'm not sure about your mobo, but people also managed to run it on other x470 boards, as seen here.

I did some snooping around and updated my bios; and I managed to find this:

It seems like I can run 4x32gb lol

Seems like it's officially supported by your bios, but that info isn't always true, see:

If your mobo says it can't handle more, it's just because the manufacturer couldn't be arsed to validate it.

You have more RAM than what's validated. I think that's a different case. If my mobo manufacturer validated 128gb, then I'd assume it can actually run 128.
Or you're saying that number is just a random number thrown in by their engineering team, which I'd hope not.
Regardless, it's nbd, I'm only looking for 64gb lol. I think I'll give 2x32gb a shot.

i meant that you usually can run more than the manufacturer actually validated.

Not in your case because there's no physical way to run more than 128gb on your mobo due do 32gb udimm sticks being the max available for ddr4 atm, and luckily it seems that Asus verified that lol
