Hi all! Not OC'd for a long time (not since OC'ing the original i7 920).
I now have an i5 8600K, ASUS ROG STRIX Z370-F, Corsair Vengeance LPX 16GB DDR4-3000MhZ and a Corsair H100i v2 AIO.
I originally OC'd the i5 to 5GhZ, temps were good but I got a couple of BSOD while gaming, so loaded defaults and started again - I had read so many forum posts and changed so many settings I got confused what I had done so started afresh.
I'm currently running at 4.8GhZ, this is stable, temps are low and I'm quite happy with it really, but it would be nice to hit 5GhZ stable.
I have currently set:
XMP - on
SVID - best case scenario
Sync all cores
Core ratio limit - 48
CPU core/cache voltage - manual
CPU core voltage override - 1.300
Power saving and performance mode - performance mode
LLC -5
Speedstep I have left on, I don't want it running at OC levels all the time
I use Prime95, CPU-Z, Coretemp and the Corsair Link Utilty to monitor my OC.
Max temps with this OC are 67, core voltage 1.280.
Now I try 4.9GhZ, I change the Core ratio limit to 49 and leave all the other settings as above.
Running Prime95 blend test, temps are stil good, core voltage is at 1.280 but after about 10 minutes one or two cores drop out. So I up the CPU core voltage override in increments and try again a few times with the same results - but what confuses me is the voltage in CPU-Z and Corsair Link still show around 1.280, even when I get the CPU core voltage in the BIOS up to 1.350? :confused:
I tried adaptive voltage and entered the turbo override as 1.350, thinking this would cap it at 1.35 - it then hit 1.470 in CPU-Z (that test didn't run long, I stopped it straight away!)
Any advice? With the temps I'm getting I'm sure I can get to 5GhZ but I just can't figure out the voltage with this 😕
I've run at 4.8GhZ for a month or so on BIOS 0614, I had LLC set to 4 then, with it set to 5 I had cores drop out, with it set to 6 my PC went through POST but wouldn't boot to Windows - in fact it went through the ASUS repair utilty and just hung doing that, I thought I had bricked it but fortunately I managed to get back in the BIOS and load defaults :eek: I updated the BIOS to 0616 this morning and had to redo my OC, it doesn't seem to make much difference if I set LLC to 4 or 5 now, but I'm still scared to change it to 6 after my previous experience!! 😮
TIA!
