So, Asrock seems to have a few quirks with how the boards run, or I am too used to Asus UEFI's now
To answer your questions:
- Power plan, I would normally use Asrock's Extreme profile or Asus Extreme Profiles, but you need to test it to be honest. I'd run a simple test of the 2 profiles, reset the UEFI to defaults, run Intel's Default / Extreme on R23 for 10 mins and see how well the system handles it and then repeat with Asrock's Extreme profile
- Cache / Ring voltage, I did notice yesterday when running a ratio of 42 it was running around 1.360. However, I'd need to test reducing it down to 1.200 / 1.250 would affect it.
- In terms of the RAM, as a general rule of thumb anything over 9333/9400 will push you into G4 mode from G2. G2 is the IMC will run at half the frequency of the RAM and G4 will run at a quarter. It’s also often termed as the Gear setting. I’d personally keep with what you have as the higher you push it the more cooling that’s going to require. 8800 is a nice spot once tuned and stable. I’ll post a few tunes to see if that helps as a guide. On a side note tREFI settings are heat sensitive and as a rule of thumb: 32K is fine, 64K needs air cooling and 128K and 262K need to be kept under 45/40c respectively.
One thing I did notice, if the RAM isn't stable out of the box, you will have issues pushing all those variables
A Few Notes from playing around with the Asrock Z890 OCF yesterday, which you may find helpful:
CPU Cache Ratio aim for 40 to 42
NGU Max OC Ratio aim for up to 35
CPU D2D Ratio aim for up to 38
SA Voltage seems more important in AL than CPUs in the past and often runs higher
NGU - 0.92 to 0.95 - A quick way to tell if you have enough voltage is running the Aida 64 Cache & Memory benchmark and the writes will be low
VNNAON - 0.85 to 1.00 - Some CPUs will regress performance around 1.00 as it doesn't have the same tricks the Apex board does.
RAM Setup
VDD2 Voltage = CPU IMC - This is the CPU Memory Voltage
Vddq Voltage = TX - This is the signal quality to the RAM
VDD Voltage - RAM
VDDQ Voltage - RAM
RAM Settings - If you are running XMP these settings can be ignored
tCCD_L sets tRDRD_sg
tCCD_L_WR sets tWRWR_sg
UEFI Settings
OC Tweaker > Voltage Configuration > Voltage Mode > Stable Mode or Change to OC Mode
OC Tweaker > Voltage Configuration > System Agent Voltage > Auto or Fixed Mode > Set Voltage
OC Tweaker > Voltage Configuration > VNNAON Fixed Voltage > Type Voltage
OC Tweaker > Voltage Configuration > VDD2 Voltage > Auto or Type Voltage
OC Tweaker > Voltage Configuration > MRC Voltage Configuration > Vddq Voltage > Auto or Set Voltage
OC Tweaker > Voltage Configuration > DDR5 PMIC Configuration> VDD Voltage > Set Voltage
OC Tweaker > Voltage Configuration > DDR5 PMIC Configuration> VDD Voltage Range > Set OC Demand
OC Tweaker > Voltage Configuration > DDR5 PMIC Configuration> VDDQ Voltage > Set Voltage
OC Tweaker > Voltage Configuration > DDR5 PMIC Configuration> VDDq Voltage Range >Set OC Demand
OC Tweaker > CPU DLVR Configuration > Ring Voltage Mode > Change Adaptive to Override > Set Voltage
OC Tweaker > CPU DLVR Configuration > NGU Memory Fabric Voltage Mode > Change Adaptive to Override > Set Voltage
That's where I ended up yesterday with the OCF
Asrock's Extreme profile
CPU Cache Ratio 42
NGU Max OC Ratio 35
CPU D2D Ratio 38
NGU 0.95
VNNAON 0.85
