Hi all,
i am French so sorry for my English. :-(
on this board I have PPVCORE_S0_CPU at 0,9v no 1.1v
also 0,9v on PPVCORE_GPU ???
PPVIN_S5_HS_COMPUTING_ISNS 12.6v ???
I hopes the CPU is not dead but what we can test or mesure. I am not an expert

0.9V is normal. Probably a dead GPU. Heat up GPU and see if it works again. After that dump it on Ebay as REAL new GPUs are nowhere to be found.

Hi dukefawks

Just heat up the GPU and see if it works again. After that you need to replace it and that is where it all goes tits up.

Does it matter? Are you going to replace the GPU? There are no GPUs to be found for these boards so this is a dead-end repair anyway.

I don't replace the GPU but one slot of ram don't accept ram it make some bip if I place one ram on it. But the other slot accept ram and the macbook works great with it.
I search where I have to look for this problem of ram slot

If you don't replace the GPU what is the point of continuing with this thing? Without replacing the GPU this thing will be dead again in a few weeks.

But anyway, RAM slots can usually not be fixed, just max out the working slot with 8GB.

ok thanks :)
I wille replace the GPU but does it possible to install another version of the GPU (most recent revision??) ? Or just the exact same GPU will be recognized ?
and the RAM slot works before we heat the board so perhaps it is just the GPU ? Today I have just one slot working and the motherboard works great. I have read all curant on the two slots and it seams to be good so perhaps with a new GPU the slots works ?
