So... what actually happens with 4 sticks of DDR5 and an Intel 12/13 gen CPU...?

[NGamer]

So, I know that running 4 sticks of DDR5 with an Intel 12/13 gen CPU does "something" vs. running just 2 sticks...

 

But, what exactly is the "problem"...?

 

 

[SpookyCitrus]

I'm sorry what? 

You're going to have to clarify what you're asking this question about. Got no context what so ever here.

[shoutingsteve]

Are you experiencing a problem with your setup?  If you have a good stable setup with 2 sticks but it gets a bit rocky with 4 sticks, then my first recommendation is to check your voltages.  Try going 3% above what the sticks are labeled as.  So if they are rated at 1.5v, bump them up to  1.55.

There's a large strain that gets placed on intels already bad memory controller with 4 sticks, so it's hard to run past 5600 effectively. It also depends on the board though since the unify x, which is one of the best board for memory oc only has 2 sticks, since at best there would be a noticeable difference with 4 sticks vs 2, and worse case it wouldn't work at all

If your motherboard supports the DDR5 ram the 12th gen should be fine

The problem is that 4 sticks cannot run memory as fast or with as tight of timings compared to 2 sticks. This is not new to DDR5, and is the reason why high end overclocking boards only have 2 RAM slots - you don't want to run 4 sticks if you are doing XOC.

So if you use 4 sticks you can't overclock...?

They can, it's just much harder. I can only get around 3333 on my 4-stick DDR4 get vs 3600 if I only have 2.

Just now, NGamer said:

So the 4 sticks would just run at the stated rating - i.e. 5200, 5600, etc...?

You can absolutely still run an overclock with four sticks, you just won't be able to go quite as high if you only had two.

 

And technically speaking, the rating on RAM is more often than not still an overclock. I think the base frequency for DDR5 is 4800MHz effective, so anything higher than that is technically an overclock.

[NGamer]

OK... so if you don't overclock - then the 4 sticks of DDR5 will run at their stated frequency... 5200, 5600, etc...?

Where do you buy a kit of 4 DDR5? I havn't seen them yet. 2 seperate kits of 2 are not guaranteed to work together properly.

No. The official supported frequency for Intel chips is 4800, so anything above that is considered overclocking. From what I have heard, doing 5600 with 4 sticks is very possible - it generally works - but there is no guarantee above 4800 speed for 12th gen.

No, you would have to use 2 exact same kits - with the exact same frequency and timings... correct...?

Yes, 12th gen is 4800...

 

I thought 13th gen is 5600...?

and from the same batch but that's just the unsure factor.

Yes, 13th gen is 5600, but you also need to take into account the motherboard, which can be another factor in memory performance. Basically all B660, H670, and Z690 boards list memory speeds above 4800 as "OC," which means that, again, there is no guarantee. I'm sure there will be Z790 boards that list 5600 as a supported memory speed.

 

Again, it will probably work fine, even with 12th gen, to run 4 sticks at 5600, but it is not officially supported. This means that it is not validated and is subject to the silicon lottery - if you memory chips and memory controller and motherboard all play nice and are of good enough quality, you'll get it to work no problem, but it cannot be guaranteed to work.

[NGamer]

OK, thanks everyone!

 

I guess I'll have to wait for the ASUS Z790 ProArt motherboard to come out and see what it all has...

 

I am looking to pair it with G.Skill Trident Z RGB DDR5 5600/6000 - 64 GB

 

Would like to run 4 sticks - purely for aesthetic reasons.

Not rather for a religious reason ?

Gotta "love" spell checker changing it from aesthetic to atheistic...

i have 4 16gb sticks of kingston fury beast running stable with xmp at full speed. no issue. z790 msi carbon wifi elite, 13900k, 4080

What is the XMP speed of your kit?

[Ebony Falcon]

Iv only seen a few people boot 4x32 ddr5 and it’s downclocked to 3600 mhz 

[PatriotGamer1776]

So I'm running a msi z790 carbon wifi fi 13th gen i9 13900ks rtx4090 1 gig m.2 4th gen and came with  2 dimms 32 gigs ddr5 6000 mhz fury.

 

I added 2 more dimms of ddr5 32 gig 6000 mhz fury obviously different lot numbers.  The bios originally set it to xmp 2800 mhz I got it to 5600 mhz with no issues.  It won't of course go to 6000 mhz.  My score on pcmark10 went up 500 points but my score on 3d mark went down 305 points but we are talking about a score of 33680 to now 33375.  So I lost less then 1 percent on points.

Just checking to see if running 4 sticks of ram on DDR5 is still having issues? I currently bought two sets of kits of 2 (4 sticks all together) but was wondering its its still an issue today? I bought the 6000mhz but was wondering If I would be able to achieve that with 4 sticks installed?
