Hallo clever people!
I have an intriguing and head-scratching situation, involving a Ryzen 7 5700g, but might apply to other CPU's.
TL: DR?
Brand new CPU/APU, on first installation would spin up and cycle/loop trying to POST, on two different rigs. Eventually posted/booted, and is now fine. How can this be?
So, some weeks ago I was in a old-style bricks-and-mortar auction house, where they had a quantity of brand-new, boxed and sealed Ryzen 7 5700g. I managed to 'win' two of them, for a reasonable price, one for me and one for some benign scalping (to cover my fuel costs, and time etc! Another punter bought the other 10 or so!)
I mentioned these to a young neighbour, and shortly afterwards he told me that a college pal would like one, but was tight for cash until the end of the month, and could I hold it?
Me "Of course! And seeing as you are a friend, he can have it now and pay me when he has the cash".
Two days later, my neighbour calls and says he has managed to find the cash, and can he come and get the item?..
Some days pass, and...
"My friend can't get it to work.. can he have his money back?"
Me "WTF?? It was boxed and sealed! Now it is used, and possibly abused and god only knows what your pal has done to it".
I asked all of the questions you might expect, and a few choice others, for good measure.
My neighbour is young, and a good and trusted friend, so I reluctantly agreed and returned the ££, and got back the CPU.
Yesterday I opened it and gave it a thorough visual inspection with a magnifying glass etc. No signs of abuse, or even of use. No liquid-metal dribbled over the pins, no bent or damaged pins. The bundled cooler was definitely not used, as it still had the factory-applied thermal paste, immaculately intact.
I don't have a bench-rig with spare compatible MoBo, so I reluctantly stripped my own and put the chip in.
The moment of truth arrived and, whirr-whoosh...
And.....
It was cycling as if trying to POST. No error codes or beeps. I don't have a Dr Debug, nor (AFAIK) any error-leds on my mobo. No output to monitor.
And I tried a few times. Fans spin up, settle, HDD initialises.. Then fans spin up, settle etc... in a loop. (I have a vid if this would help)
Hmm! I surmised that perhaps it was somehow pre-set to use the on-board IGP, so I went and found a HDMI cable, and plugged that into the MoBo output. Tried again. And again. Then.... the BIOS/UEFI screen flashed on my monitor... and then it went back to cycling in a loop!
I disconnected the HDMI cable, and reconnected the Display Port to my Graphics card.. Switched on and.......
Guess what? One beep, straight past the UEFI and tries to boot Windows! It would not of course, due to TPM and different CPU etc...
Back in to the UEFI/BIOS, a quick reset, and everything is running beautifully! How can this have happened?
I have:
GigaByte Gaming B550M, BIOS F14e, 2x 8gb Corsair 3600 DDR4, NVidia GTX 1070. All were working perfectly with my previous Ryzen 3 3100
The FoaF, (I am told) "Knows what he is doing":
MSI Mortar MAX B450M, up to date BIOS. He tried with only one stick of RAM etc.
He said the CPU was "getting warm", I asked via my friend, "how did he know, was he running with no cooler and using his finger?" My friend replied that he has a temperature-probe-gun thing.... (?)
