i9 13900k with XMP, too much?

[Panzerlang]

Puh.
GIGABYTE Z790 AORUS MASTER LGA 1700 Intel Z790 EATX Motherboard with DDR5
Intel Core i9-13900K - Core i9 13th Gen Raptor Lake 24-Core
G.SKILL Trident Z5 RGB Series 32GB (2 x 16GB) 288-Pin PC RAM DDR5 7600 (PC5 60800)

After lots of testing malarkey it would seem that running the memory in XMP, so that it hits its rated XMP frequency of 7600mhz, the system becomes very flakey. Prime95, most of the cores shut down almost immediately. I disabled Hyperthreading, no difference.

I always thought XMP (dual channel mode) was just a way of making a pair of sticks work more nicely together, I didn't know it was over-clocking the sticks.

So, is running the sticks at 7600mhz too much for this CPU or do I have a duff CPU/mobo/RAM?

NB: Before I updated the BIOS the system refused to boot at all with XMP. Afterwards it booted and appeared to be fine. It ran UserBenchmark (UserBenchmark: PC Speed Test Tool - Compare Your PC) ok and scored 93rd Percentile but blue-screened with IL2.

Any insights would be much appreciated. Maybe I have to manually fine-tune voltages or something?
Oh, CPU temp in HWMonitor running Prime95 with default BIOS settings, max 97c.

You should have more than one XMP profile, at least one is an extreme best case scenario.  Not every processor and board is compatible, Intel locks out speeds on its lower end of the series chips seemingly deliberate, your at the top so you should be able to get close. 

 

You can set the speeds and RAM timings manually and work your way up toward the speeds listed, checking for stability as you climb the ladder.  Had an 11600K and was able to stably clock faster memory beyond what that CPU was rated for, it wasn't designed or listed to handle the higher memory frequency's, but I got fairly close to the memories listed speeds quite above the listed limits.  An 11900K it's no sweat to get the max freq's.

Here is a link with Long read about OC a ASUS motherboard : ( but guess the logic is the same all MB )

It's not my language, and pc is not my job - but in a few days I upgrade my pc to a Asus strix MB and system similarly to yours , and I will take a further look to what's written

I've got it running IL2 stable with the RAM at 6400mhz, found a bunch of profiles under "DDR5 Booster" (or something like that). I have no idea if all that is just another term for XMP or if I'm losing something to do with "Dual Channel".

Thanks guys.

Well, the benchmark no longer says anything about Dual-Channel needing to be activated so I assume it is.

If that's the case I do not understand why the BIOS creators feel the need to split and name differently the exact same things in separate sub-menus.

If you go to Gskill webpage and search for the Qualfied Vendor List of Mobos for that RAM you will see the Mobos that theoretically support that XMP profile:

Only top Mobos support that XMP profile.

Cheers dude. My board ain't no Tachyon. Lol. But I'm happy with 6400mhz.
Dual-channel is enabled by default from what I've learned (so long as two or four sticks are installed, and in the correct slots in the case of two).

Something is definitely borked with these DDR5 boards (not just Gigabyte, I'm seeing numerous reports from all brands with the same XMP issue). The latest BIOS specifically mentioned improved support for XMP 6000 but I've now tried G-Skill Trident rated at 6000 XMP and couldn't get it to boot at all. I thought maybe the timings were too tight (36 CAS) but I've put the 7600 back in and selected a profile (Samsung) that has 36 CAS (previous profile was Hymix at 42 CAS) at 6400 and it runs sweet as a nut. And the profiles are XMP, the sub-menu heading is "DDR5 XMP Booster". So, I can run 7600 at 6400 with CAS 36 under an "XMP booster" profile but I can't run 6000 at 6000 with CAS 36 under "XMP".

Go figure.

Welcome to the Show. I have an 11900K on an Asus ROG Maximus Extreme III with 128 GB, and if I set the XMP profile as set in the RAM that is DDR4 then the BIOS sets a memory error during post. I run then the standard 1333 MHZ instead of the XMP profile at 2000 MHZ. The board is advertised as going even much higher.

So you need to tweak manually and yes you can make it work, but frankly the gain in applications, is invisible so it is too much effort just for the sake of it. Only specific memory tests that just measure that will show the difference. CPU clocks that is what makes the real difference. Running at 5 or 5.2 MHz all cores instead of 4.5 all cores make a visible difference. If we could have 6 MHz flat all cores without too much fuss that would be a fantastic gain.

I have just bought an Asus ROG strix Z790 a E gaming  - CPU I7 13700 - G skill 6600  ( and new CPU waterpump ) 

My GPU is 3090 

 

IT was easy - the motherboard have a OC program and 1 click its run up to 6000 MHz and no problem with that Ram and XMP - 1 click in Bios 

 

And yes - it's better than my z390 , I5 9600 : 5200 MHz and old ram around 3000 

 

Maybe I manuelt can OC it more , but I'm  not and expert - and now I use time for in game settings find the 'holy grail' ?

How much better is the performance and do you play in vr?

Ooooh yes , there is no other possibilities ( for me ) , I have never tried play with flat screen - and its a reverb g2 

I can not say how much better it is , thats diff in words - but sure its much better  

 

Now over the next day try in settings to find the sweet spot 

[ACG_Ginger]

XMP does not over clock your RAM , it just lets it run at it's stated setting , when you get ram it's always set low by default.

But I see 6000 MHZ for one core in your picture it is core 0. What about the other cores you have them all or say all the performance ones at 6000 ?

Thanks I have a 9700k oc to 5.0 with an 3080 and was curious how much better a 13700 would be. I too have a g2

As i see it , it is all the cores - but they are flexible from 4500 to 6000

Yes - but I think it's all together - new MB / CPU / Ram

I have the exact same components. Bios to 8a. Still can't get the 7600. Only get 7500. Did different settings and voltages testing with mem86. Max I could get with the standard XMP is 7500mhz

I have an Aorus Pro by Gigabyte.  Found this little vid and it worked for me...running 12700kf  (Alder Lake) with 32gb G.Skill DDR5 5600, MSI 4090.  The DDR5 ran at default 4800.  Followed the vid and it runs at 5600 as advertised.  Fast Boot must be disabled or else you will get black screen and no boot.  My DDR5 timing is 36-36-36-89 @ 1.25v.  

 

Hope this helps

 

Salute!

DDR5 and DDR5 memory controllers are still pretty new, so things will likely be touchy for at least to Raptor Lake Refresh and Zen 5.

 

You may ran to run the VR benchmark at your preferred game settings at both stock DDR5 settings and at the XMP settings to see if you are getting much out of them. On the Zen 3 platform I found the 2366 to 3600 was a 9% boost, but almost nothing with the Zen 3X3D. It may well be that Raptor Lake is very sensitive to memory timings, or fairly insensitive, but you'll only be able to see by testing it. 

[IckyATLAS]

On the internet there is a lot going on about Asus Motherboards that do overvolt the CPU when one is using XMP profiles.

This is true on Intel and AMD platforms. It seems that the problem is worse on AMD platforms for the latest AMD CPU's as the overvolting that the mainboard does will kill in multiple occasions your CPU and also damage your board. Even if the motherboard and CPU manufacturers push for overclocking according to their own specifications BEWARE! your warranties are worth nothing.
