Is 6000MHz C36 DDR5 memory too much for 12600KF with XMP?

[themikinico]

I am getting a new system and will get the 12600KF (as it was very cheap compared to 13600KF) and was wondering whether having DDR5 6000MHz C36 is too much for the processor even with XMP allowed.
I'm not looking to do manual overclocking myself.
I got a MSI Tomahawk Z690 DDR5 motherboard already (and 750W RMe Corsair PSU)
This is my RAM: https://www.amazon.co.uk/gp/product/B0BZHTVHN5/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

(NOTE: I posted this also in the Cooling & Overclocking since I wasn't sure which would be the best forum)

What do you mean "too much".

I'm running a i7 12700K , Z690 with 32GB DDR 5 6000 C36.

It will be a good combo.

You'll be fine for single-rank stuff for sure.

Oh by too much I meant whether it would be unstable (I saw in multiple places mentions that if you have too much RAM for your CPU to handle it will slow your system down)

Thanks for the feedback!

Thanks for the response, I looked up what single/dual rank meant but I'm not sure I fully grasped it. With the two RAM sticks I sent put on the recommended motherboard slots, it would be single-rank?

 

[ir_cow]

2x 16, 2x 24 are single-rank
2x 32, 2x 48 are dual-rank.

Assuming it's 32GB of DDR5-6000, you will be okay. Plug n play. Since it's Z690 Motherboard and 12th gen, you'll probably max out at 6400 for that setup.

I would update the Motherboard BIOS as well. Small performance improvements and memory compatibility.

(I saw in multiple places mentions that if you have too much RAM for your CPU to handle it will slow your system down)

Not a thing. It will either not boot and or be unstable. Example is filling all 4 slots or in your setup using high freq dual-rank memory.

Unless by slowing down actually means running slower memory so it doesn't crash the computer. Than yes, kinda. Slower memory can impact game performance.

 

[P4-630]

Or just check the motherboard memory QVL and buy a memory kit that has been tested to run at their XMP speeds on your board.

Thought these issues were more with AMD...

 

[bonehead123]

It will be a fine combo, as long as you hold it right, hehehehehe

Sorry, couldn't resist....

Ok I see thank you for the advice!

Perhaps you heard 4x dual-rank running slower due to IMC limitations?

Yep I did, i got 2x 16GB in the end and it works well, thanks!

I know it's an old post, but i got a i7-12700K and i'm thinking of upgrading memory from 2x8 16GB DDR5 4800MHz to 2x16 32GB DDR5 8000Mhz. Is that fine? Would the XMP 3.0 work properly on this rig?

You'd get better performance with 13th or 14th Gen, then get 32gb 2x16gb 8000mhz kit.

100% will not work at 8000 MT/s with 12th gen. You're highest bet is probably in the 6800 range without tinkering.

Your motherboard also plays a roll in this too. Assuming it's also not a 2-slot Z790 MB, you will want to stick to around 6000 for that 12th gen.

Are the Raptor Lakes not having any issues with overheating or wrapping? Isn't that why Intel made up some bullshit about the bios settings?

Can i just run the memory at 6800Mhz even though the XMP is set for 8000Mhz and just don't set the XMP until i get the 15th Generation Intel when they come out?

You'll need a next gen motherboard too though..

Sure can, just run the memory at a lower speed. Easiest way would to enable XMP, and before rebooting manually change the frequency to your desired amount. IE 6000~

@P4-630 pointed out already that 15gh gen (aka Ultra 200 series) is a new socket. You will need a new motherboard. By that point in 6 months you are overpaying for memory since 8800 MT/s is just around the corner making what is currently "ultra fast" cheaper as the next halo product takes its place.

No more than the 12th gen before it

Overheating and warping-

No, can't say that would be an issue when it's like 20% better than 12th gen with the same memory you're using now.

Bios settings depends on the tier of the motherboard. You're not exactly running an Apex or even Hero from Asus. Just their Asus performance enhancement alone makes the cpu a frying pan.

And it's at least slap in performance gains on your part. You may not need the memory unless you need more capacity. Gains will be CPU IPC increase from 12th to 13/14th gen.

 

[Dyno]

Yes, it's a LGA 1851 socket. Probably will wait since another user pointed out that the DDR5 8800Mhz will be out by then.

"6000MHz C36 DDR5 memory" is often too much for the ram itself.
There are 2 types 6000MT/s. One is CL36, the other is CL30.

CL36s are usually made of Samsung dies. They barely reach 6000MT/s CL36. That's why I say it is too much for the ram itself.

I highly recommend to get CL30 ones.

I am running my 12600kf with an SP of 68 (was 75) and an IMC SP of just 45, I have been looking everywhere to see how far above me people have gotten with better binned 12th gen K cpus but I can truly proudly say I am running this second stable at 7400mt/s at cl 32, on a $109 32gb Patriot kit at that! I already know, yes it shocked the $*it out of me too, but in all fairness I have been around the block for a minute, and not even bragging, I just have had a lot of really good luck, I may not be #1 or even #10 in most leaderboards of most benchmarks, however for 3d Mark, because I bin my personal hardware very carefully, or well not even that, I am just a picky binner! Also, when every new gen drops I buy an i5 and an i9 the first available opportunity, so I had this 12600kf sitting in a box next to a 13600kf that I just sold, but tbh the 13600kf was a true monster for an i5. That i5 had a cpu SP of 89 (avg between P and E cores, with a 96 P core SP!) and an imc SP of 74!

Due to the high imc SP on the 13600kf, running it in 3 different Strix Boards and also in a z690 Hero, that i5 scored highest in every 3d mark benchmark i participated in, when put against the same setups with same hardware, and indeed the imc in the 13600kf was better than in my 13900k, that has a cpu SP of 110 and is sitting in a new build now thats almost finished, but paired with the same 4090, and both 13th gens capable of 6.2ghz, in almost every benchmark with the 4090 that was GPU bound only, it scored higher than the i9, and could sustain slightly better memory OC than the i9, which is strange but proof that a good imc is so important when it comes to overall perfromance!

Im quite certain that 7400 cl 32 at 1.45v is the best I can expect of that cpu. I had it running at 7600 cl 36 for about 20 min and then it would error out, makes me wonder if these Patriot 7200m/t modules are going to be some killer binners, i was so happy to see them post on xmp 1st try. I don't even have an extra fan cooler on my modules, so if someone has seen higher than 7400 stable on 12600k /kf ? please lmk

7400 is pretty crazy honestly for 12th gen. Passes Memtest5 and y-cruncher 2.4B?

Sorry for the late seeing this, yes I agree it is crazy, but as nothing does it did not pass in the built in memtest in bios, but nothing does... lol.. but for sure it passed memtest64 on a 4 hour run stable. In all fairness i beleive I degraded the %$&t out of that 12600kf though, as the SP score dropped 8 points after just 3 weeks of use, but when I put my 13900k in I managed to hit 7800 on the same 7200 sticks and was good for about 2.5 hours then started going wonky, havent had time to mess with too much but they run at 7600cl34 @1.48v/1/48v and 1.34v on imc voltage. I know I can squeeze more out of it! When I am done working I will post some screenshots as the aida64 memory test results are pretty narly too!. I am unfamiliar with y-cruncher

12600K, Z690 and 32GB 6000MHz CL 30 perfectly stable.

What voltages are you using for the cpu? 12900k here, 7000 c32 is maxed out with reasonable voltages (1.2 SA, 1.25 vddq).
