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.
