Hello,

I have built a new computer (10900K, Maximus Hero XII and 8Pack 32 GB 4000 MHZ memory (MY-096-TG)). This is the exact same memory that is being sold as upgrade kit. I have inquired with CS prior to buying it querying that the CPU, according to intels own ark page, cannot handle these speeds. I was advised this was not the case and it would. Well, I built the thing and:

1. Bios only posts 2400 MHZ

2. CPU ID shows 1200 MHZ and AI Suite shows a maximum of 2400

What am I missing?
 
Hi, is it 4x8GB or 2x16GB. Also you will need to set the RAM speed in the BIOS or run XMP which will set it automatically, if it doesn't post, reset it and increase the SA and IO voltage as well as the RAM voltage. Currently I have a similar set up to you with a 10900k and 4x8GB of G Skill Trident Z RGB at 4000MHz, my current SA voltage is set 1.248 and my VCCIO voltage is at 1.264v. My RAM voltage I think is at 1.38v. Try along those lines as a starter.
 
Yeah, you’ll need to enter your BIOS and enable the XMP profile. Then once in windows run something like CPU-Z, on the memory you should see it at 2000Mhz (DDR = Double Data Rate so 2x2000Mhz will be ‘4000’ in reality.

Likewise, 3600Mhz RAM would be 1800Mhz and so on and so forth.
 
Thanks guys. This was extremely helpful and I have activated XMP within Bios. This prompted 4000 Mhz in Bios and 2000 Mhz in CPU ID. That is not where it ended though. I have since had multiple game crashes and several BSODs (IRQL not less or equal). I have run Memtest which has found multiple errors and then quickly resulted in another BSOD (memory management). I have now reverted to to auto settings (in effect slowed the RAM down to 2400 again) and am currently running memtest again.

As for my setup:
Asus Maximus Hero XII
I9 10900K
Team Group Xtreem "8Pack Edition" 32GB (4x8GB)
Seasonic Focus GX 850
NZXT Kraken Z63
MSI Gaming Trio X 3070

Essentially I am running the same hardware as an overclocked bundle Overclockers used to sell. I had questioned compatibility prior to purchasing over the phone but was told it would not be an issue.

Am I just the worlds most inept person or have I run into an issue here folks?
 
What voltage is the memory running at? The product page says 1.2-1.4V. Assuming it's at 1.4V for XMP, maybe try 1.43 and see if it's stable.
