Overcloking on Asus Maximus XI Extreme + 3x I9 9900K how to test fast an OC to choose the best one

Hello

my last computer was 5 years ago and look many change on bios oc etc...

Can you pleas give me the steps and setting on bios to test wich 9900K is the best on those 3 9900K ?

i hear like on this motherboard i have to disable hum... avx..if i remember...

i have on this computer to test them an NVMe hard drive and G. Skill at 41xxmhz

for the stability test i will use Prim95 26.6 with der8auer setting and cinebench. i want to test them fast and when i identify the best of them i will work on OC it more seriously

thank you

Follow any one of the many OC guides.
Use realbench instead of prime 95 as it uses real workloads. IMO prime95=how to make CPU into space heater. Ive seen them pass 24+ hours of prime 95 then lock slap up on a real workload.

You dont have to disable avx, just an offset so avx instruction sets arent running full bore. Example multiplier of 48 with avx offest of 3 would give you 4.8 GHz unless its an AVX load then it will drop back to 4.5 by dropping the multiplier by 3 points.

thank you but man i dont know where to go to put what you saying and the exact value 😞

you are expert or used to do that not me 😉

AVX offset within the UEFI lets you reduce the core multiplier under AVX load, it is not necessary to disable AVX entirely. The value needed depends on the CPU sample.

Do the following but leave XMP disabled.

1) Sync all cores to 50

2) Set CPU Voltage to adaptive mode and set an Additional Turbo Voltage value of 1.35v

3) Under Digi+ set Loadline calibration (LLC) 6

4) Download and install Intel XTU

6) Run the test for 1 hour


Report back with what you find. XTU does not use AVX instruction sets and should give you a good baseline for stabiltiy.
