Windows 11 allows for 5866Mhz at CL21
with no cpu oc. (pic below)
With Win 10 could only hit 5866Mhz CL22 (with no cpu oc). Kinda weird nothing else has changed, all the hardware bios everything remaining constant - except moving from Win10 to Win11.
Could always run 5866Mhz CL21 with added voltage and a proper CPU overclock of 5.1Ghz, but since it's RKL, that adds additional heat.
Also purchased and installed Microsoft Office Home and Business 2021 yesterday, and the simple work apps really LOVE the high speed Hynix DJR kit, responsiveness is off the charts amazing.
Win10 to Win11 - more responsive
MS Office 2019 to MS Office 2021 - more responsive
Gskill 5333 kit OC'd to 5600 or 5866 - more responsive
WD_Black SN850 NVMe SSD in the Rocket Lake PCIe 4.0 M.2 slot - more responsive than Optane 280GB PCIe 3.0
Finding the thermal and performance "sweetspot" for working long hours - is priceless. https://i.imgur.com/VmDiOfL.jpg
Below is the extremely simple 3-minute XMP overclock for the Gskill F4-5333C22D-16GTES mem kit:
1) set XMP
2) set 5600 or 5866
3) set DRAM voltage to 1.625v or 1.725v respectively
4) save out of bios and reboot
Yes, that's with no CPU overclock, but RKL's increased Single Thread over Coffee Lake and Comet Lake even the 11600K i5 at stock 4.9Ghz boost feels very responsive with the high-speed Hynix DJR.
If you are running an 11900K, then your stock single core boost is way up at 5.3Ghz. I would guess even more responsive.
Hoping EVGA comes through and allows the Z590 Dark to take full advantage of the super high-speed Hynix 5333 kit for you guys, I really want to consider the EVGA Z790 Dark for Raptor Lake next year.
Where's that bios update?
