How's everyone getting on with overclocking?

Don't seem to be able to go above 5425mhz all core. Running Thermaltake Phantom Spirit and PBO +200 CO-30 (mine is actually stable at -40 but can't see any difference in performance).

Temps are good 48 degrees idle, 57 average when gaming (spiking up to a max of 68) and hitting 90 when benchmarking, all using a low rpm silent fan curve with a Thermalright Phantom Spirit air cooler and some very old Artic MX-2 paste.

Set my IF to 2200 yesterday which improved all benchmark scores and games' fps by 5%, but it's crashing today on desktop/low usage. I suspect I need to change the SOC voltage but I don't really like messing around with voltages and my Asus voltage bios settings are confusing. The recommended is 1.15 volt at 2200, but the Asus stock auto settings are running at 1.264, so I dialled IF back to 2067 which is stable.

About 2 weeks ago i was mucking about with asynchronous clocking for lulz. Had it at 5.6 but even funnier your idle clocks are a minimum of 4.8ghz it doesn;t downclock past it. This was on an Asus board as well.

To answer your question. Funnily enough stability gets worse when you run a higher Vsoc voltage with a higher Fclk. Bet you could get away with 1.20 Vsoc voltage

Ive updated trhe bios to the latest 3201 and the CPU speds are still all over the place.

It's a problem with Core Temp, I just tried it on my 9800x3D rig, and it was trying to tell me that at 1.4Ghz all cores, Cinebench R23 was giving me 20k. This was with -35 CO, +200Mhz as well.

:: edit ::
It reads the 7950X fine though, most likely the 9800x3D being too new that the software doesn't know how to read it's data properly yet.

I tested on my 9800X3D and the same issue.

Used HWmonitor and shows 5.4ghz all cores, PBO of 200+ and a -30 CO

Ahh, great so it's just coretemp lol, surprised it hasn't been updated yet. I've just checked task manager and that seems about right, boostting to 5.2Ggz. Iive installed HwInfo ibut sn't showing any CPU sensors. Do Is not show them by default?

That's one of the problems solved, just got to figure out why none if my 4 SATA drives are showing in windows now but that's one for the B650e-e motherboard thread. One of those drives contains my user profile so I get loads of errors and no desktop and that has been a distraction with this CPU issue. And that the first 9800X3D I tried yesterday was faulty and reboots as soon as windows starts didn't help and wasted about 5 hours.. doh!

Chipset drivers update maybe?

Or, BIOS settings. As when you update BIOS, they often get set back to default, and the SATA settings may have got set to RAID or other for it's setting instead of AHCI or whatever it should be.

Do the drives appear in the bios? if not then make sure the controller is enabled.

I've disabled mine due to only having 1 NVME drive
 
For some odd reason I lost my OC settings and had to re-apply, it might have been when I upgrade the BIOS.

I setup the following PBO +200 CO-30

Temps run about 61 whilst gaming in a mini-itx case and appears all stable.

What else do I need to change and what is the overdrive scaler ? I set it to 5 but should it be 0 - 10 ?

I received feedback yesterday to confirm it wasn't faulty.

I do wonder now if I didn't leave it long enough for the RAM to train. I left it a good 10 mins but I've since read online it can take up to 20 mins.

I'm curious to hear from people who have successfully installed, roughly how long it took for them?

I had trouble running "EXPO" settings with my motherboard (Asus PROART X870E-CREATOR WIFI) + RAM (Patriot Viper Venom 2x32GB 6000MT/s CL30 sticks totaling 64GB) combo, and the RAM isn't on the QVL.
I instead manually overclocked, first to looser timings than my RAM was rated for (I used the QVL list to reference a similar kit), and manually set the voltage, and it took 30-60 seconds to train the ram.
Then I tightened the timings, which took another 30-60 seconds to re-train to the equivalent EXPO settings:
6000 MT; 30-40-40-76 ; Trc 116; everything else auto.
So that gives Speed: 6000 MT/s, MCLK: 3000, FCLK: 2000, UCLK: 3000
Voltages:
CPU V-Core: Auto (reporting 1.27v)
CPU SOC Voltage: Manual 1.05000v (reporting 1.074v).
DRAM VDD Voltage: Manual 1.4v
DRAM VDDQ: Manual 1.35v

I think in my case the issue was the voltage probably wasn't being set correctly...
Weirdly I had the exact same issue on my X570 Aorus Elite (from Gigabyte), where I had to manually set the voltages and then that ram worked at the EXPO settings just fine.

Maybe I could tweak them more but just having them run at their rated speed is fine for me really.
I haven't tried setting up PBO yet, I haven't really looked into it yet either and not sure if I will.
