Adding 2 more sticks of DDR5 Ram 64gb for a total of 4

[weagudelo]

I am currently using two sticks of CORSAIR DOMINATOR PLATINUM RGB DDR5 RAM 64 GB, on a MSI Z790 Ace Meg Motherboard, but would like to fill in the empty ram gaps and buy two more memory sticks of Corsair Dominator Platinum RGB DDR5 Ram sticks. The additional 2 sticks of Ram cost around $300 us dollars. They are kind of expensive. The thing is that I will no be able to get a refund, if they do not work well on my rig, since I live overseas. What should I do? Any recommendations or suggestions?, please!

There can be issues running 4 sticks but it all depends on what the memory controller in your CPU can do.

4 sticks can lead to not running XMP/EXPO, needs manual tuning and can overall bring a lower speed with them.

What do you need 4x64GB for? If it's for workstation and server related things you shouldn't care about the speed that much more stability if it's for gaming keep what you have.

will work fine, as long as they are identical not just in spec, but chip used.

as long as you can get the seller to confirm what dies are used on them, and confirm (they are identical to yours)...

Depends on a lot unfortunately, because you can rapidly run into timing and stability issues when using 2DPC. What speed is the DRAM that you're using?

Don't you mean you have 2x32GB sticks and plan to add another 2x32GB sticks?
If so, there's a high chance you won't be able to reach the current frequency you have now, and may need to drop down to 3600~4800MHz.

Don't do it. 4x DDR5 never does well. If your just going for looks, you could just not enable XMP but that seems like a big waste of money. Countless threads on TPU about this exact same subject.

Why not try the Corsair Dummy sticks? Lighting kit or something it's called.

DOMINATOR TITANIUM DDR5 Lighting Enhancement Kit — Black

TITANIUM Light Enhancement Kit completes your PC’s look by filling your empty DDR5 slots with modules boasting 11 vibrant, individually addressable RGB LEDs each.

There should be more 2 slot mid-high end boards to discourage this behavior

I just bought 2 more sticks to see if this is true

I saw that Corsair and Kingston have 4x 16GB kits of 6000 and 6400 validated for my board and CPU series.. I am not running either of those brands, but with the new AGESA updates I think it might be ok.. if not then oops..

For science!

 

[ir_cow]

I bought the dummy sticks for DDR4 a few years ago. Would not boot all the time. $20 wasn't so bad to find out.

 

[freeagent]

Maybe I can tame the beast.. maybe I cant.. find out Monday

As long as they are the same type and same revision (important with Corsair sticks), should work. 4x sticks will significantly lower your attainable memory speed, though. Expect no more than 6000 with 4, 5600 is more realistic but could be as low as 4800-5200 depending on CPU

If I can nail down 6000-6400 I will let me buy me a coffee

4x 16GB is way easier to run than 4x32GB or more.

i'll buy you a coffee if you manage 4x 6400 Dual-Rank!

Sweet, next time I will let you pay for the hardware

 

[igormp]

I already paid for 4x that amount, will report how it goes once I have it in hands

@damric
no, anytime a board has 4 slots and you can buy kits with 4 sticks that fit, companies need to make it work.

forcing +90% of users to know detailed things like this, prior to buying just to get stuff to work is a joke, anything else sold that way and ppl would be on the barricades.

 

[freeagent]

If I cant get it to work the way I want it to, I have a guy at work who will buy a kit from me. So either way its for science, and I lose nothing.

 

[Epaminombas]

update the BIOS and do a ClearMOS with just 1 stick

Then you install the other 3 sticks

But you will have to work at a fixed frequency of 5600Mhz.

Yeah but just don't expect to run 8700CL36 like my $99 2 slot board

 

[Waldorf]

oh sure, just the common stuff around the systems sweetspot range should "always" work.

 

[freeagent]

Either my ram sucks, or my OC skill sucks because I cannot nail down 6400 with 2 sticks lol. So at this point just running a tweaked EXPO is good enough. I can bench and stuff at 8200 but I cant get anything to be stable lol.

*Glances fondly to AM4 sitting in a box*

 

[ir_cow]

When in doubt, more voltage! MORE! Until the CPU is dead

3x 7950x servers with 128gb ram and the best I can manage is 5200. Which is fine because they are servers and I don’t fuck with the clocks but when I was testing 1 (before I bought the other 2) it absolutely would not do it.
