PC wont post. EDIT Cpu stuck at base clocks

Tested on my other board and the chip boosts with the voltage lowered. Now ive no idea. Unless its a gigbyte thing?

Cheers for the tips mate. I appreciate your help :)

Your other board what make is it?, i would say its a outdated bios on the gigabyte board, have a friend that had a similar issue on am4 and once the board was updated the cpu was working correctly and running cooler. completley forgot about curve optimiser.
 
Thanks. Is there an Intel equivalent? I was thinking of undervolting my W3580 when I give that PC to my son,as it does get toasty in the summer.
I'm not to sure tbh with you mate. Hopefully someone here can chime in. I just used to lower the voltage manually on intel cpus until it became unstable then added voltage accordingly.

The other board is a rog strix b650e f. The gigabyte board is on the latest bios. I've tried 3 other bioses but the same happens. Just a thought... would it be because the 4pin cpu power isn't connected? I've only the 8 pin connected.

you should always use the 8pin eps plug first, connecting the 4pin aux will cause problems when the cpu needs to pull power, may explain why your cpu was stuck at 4.7ghz instead of 5.4ghz boost, not sure the exact power a 4pin cpu power can provide but i would say its around 75w, as the 8pin eps can provide 150w which would allow your cpu to pull more power and get to advatised boost clocks.

Sorry I meant to say the 4 pin isn't connected. Just the 8pin.
 
OK so I've plugged in the 4 pin Haswell and the issue remains. Going to try the f3 bios now.

Edit. Same with the f3 bios.

your new cpu, and your mobo is working as intended when you didn't play with bios settings and boosting correctly?
then you played with bios settings and now no longer boosting correctly?
if so then pebcak.
reset your bios and try again. would suggest using a less aggressive curve optimiser first and not touching other voltages.
 
Think curve optimiser works fine but when he inputs a fixed core voltage it doesn't boost above the base frequency, sounds like this is by design.
Correct. Im starting to think that. Would rather do a manual set voltage.

I can use dynamic v core voltage though. Under prime95 it sits at 81c and 1.278v and boosts to 5.4ghz. Any lower on the dynamic vcore and it crashes. Also have a negative 20 on curve optimiser.

Can you clarify exactly what you have tried and what the issue still is?
Basically if I set a manual vcore, it wont boost past the base clocks no matter what I try. Even if I set it at 1.4v to test, it does the same thing and wont boost above base clocks. Only the auto setting on vcore voltage will the clocks boost as normal.
 
Hi chaps.

Temps were getting 95c with auto cpu voltage settings so I tried to lower the temps by reducing the cpu vcore. when I try to lower the CPU vcore voltage, the CPU no longer boosts and stays at base clocks. I've gone as high as 1.4v but the issue remains and wont go any higher than 4.7ghz. I've tried enabling pbo with both auto, motherboard and manual limits, ppt, edc etc etc.. Also tried setting core performance boost to on, expo/xmp on and off also.

Been looking online all night for a solution but everything suggested doesn't work.

The CPU will only boost when the CPU vcore is set to auto and nothing else.

Is there a setting I'm missing here?

Cheers

Done all the above bud and the issue remains. I've given up with it tbf unless someone has a different suggestion to try.
