13900KS, Z790 Strix E-Gaming, only getting 32K on Cinebench R23?

[RickSinGA]

Just built a new system primarily for MSFS 2020 and in stock format I am only seeing Cinebench R23 scores of around 32K and from what I gather I should be pushing 40K stock?

Rog Z790 Strix E-Gaming WiFi Bios 0816
Intel I9-13900KS
G.Skill Trident Z5 RGB DDR5-6400 2x16GB
Asus Tuf RTX 4090 gaming Graphics
EK Quantum Velocity2 Waterblock w 2 60mm 420 Radiators (push/pull)
Thermaltake 1350w Gold PS

I can OC to 60/59/45 -0.075 Offset (using Intel XTU 2.0) and improve my score from 31K to low 32K but from everything I have been able to find I should be seeing at least 40,000 on the Cinebench R23 benchmark. Set the XMP to Tweaked in the BIOS, everything else was set to Optimized Defaults.

I assumed it was a bad CPU and B&H sent me a new one, marginally better on the SP scale from 103 to 112; which did improve the OC slightly but that isn't the problem from what I see.

I also had some DDR-5 6000 which saw my scores lessen slightly, so that is not it!

Also have the latest Intel ME drivers and firmware. Armoury Crate updated all drivers etc.

MB? Power Supply? etc?

Any ideas?

Does anyone know why windows changed to see only 24 cores? That is so odd.

Yep, akgis_* is a genius for sure. I've been using PCs for nearly 30 years and I had no idea that option even existed. Nice one 🙂

hehe iam no genious just some google fu after I found that 8e-cores were missing from windows.

I noiticed this because HWinfo was just showing 8p/8e

Glad it helped you OP 🙂
