Hi everyone. I built a new pc. 7600x, b650 gaming x ax v2, corsair 2x16gb vengeance ddr5, corsair 850e modular psu, gigabyte rtx 2060.

All was working well. But I left the PC on and had to pop out. I returned and the PC was off. I tried turning it on and nothing.

The DRAM light is on and I can't get passed it. Been trying g to get this to post for hours now and nothings worked at all.

I've tried the following..

Reseating the cpu

Removed the gpu and tested with another card and integrated graphics.

Tested each stick in every slot and left for at least 30 mins incase of training.

Updated the bios using q-flash plus

Cleared cmos

Removed everything from the board except cpu, ram, cooler and psu.

Could both sticks really of went at the exact same time? Or could it be cpu/memory controller related?

Any help would be appreciated. Cheers

I’d probably start with re building the basics out side of the case, just the cpu, cooler, 1 stock of ram. Just to have a base line.

From there sadly if still not working, might have to troubleshoot the ram first, then the cpu then the board I guess.

Have you verified no bent pins etc. in the socket?

Yeah its out of the case and still doing the same.

Socket looks good to me.

Could It be the power supply?

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

When you lowered voltages to tame temps what were you getting with regard to clocks and temp after, am5 is designed to run upto 95c all day long.

Cooler choice is fairly important if your on a air cooler temps will be generally higher Vs a aio/custom cooling

For the extra 300mhz boost and the extra temp and voltages I would undervolt and stay around 4.7ghz, In games you'll see no difference Vs 5ghz but you'll see lower temps and voltages will be better.

My 7950x has been undervolted and I use pbo to get around 5.4ghz in games, which s lower than the max boost of 5.7ghz but I run at just over 70c Vs 95c, YMMV though every CPU is diffrent

Clocks were 4.7 and wouldn't budge unless I turned the cpu vcore setting back to auto. Then It would boost to 5.4 as normal but the cpu vcore voltage was 1.4v in HWinfo so I decided to lower it. Even if I set the vcore to 1.4v manually, it wouldn't boost to 5.4 like it does on auto. Not sure if im missing a setting somewhere. Cooler is a 360 corsair aio.

Auto volts on amd usually sit around 1.49-1.5v, that's quite high tbh, I would say it's because the voltage is being 1.4v or lower is capping the max boost of the CPU, unless your doing work that requires a lot of CPU, I wouldn't worry too much, you can check bios updates too as newer versions improve performance, but a big tip don't update to the latest as they are quite buggy, try to stay around 2-3 below the very latest to be safe.

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 :)
