Hello,

I have an old GIGABYTE GA-8I945P-G-RH, for which I buyed 4x1G "ELPIDA 2Rx8 PC2-5300U-555" DIMMs. All the units works, and all the sockets too (I have tested one by one in every socket). The MoBo support dual channel for DDR2 667MHz DIMMs

When I install the 4 DIMM, the MoBo only recognize 2.6GB (Windows 7 sees the 4GB, but only 2.5 are usable). No way to get the 4GB changing the position og the DIMM in the socket.

Reading and reading in the net, the only I have seen is that these old MoBos use part og the RAM installed for the internal GPU and abother peripheals (?)... I do not know if this is true or not, but if it uses 1.5GB of 4GB for other purpouses than the RAM I have done a bad business buying this RAM

My BIOS do not have the option to disable the internal GPU (I have installed the last version offered in GIGABITE's page, F4). I know that in this BIOS you can access to hidden options by CTRL+F1, but there is not that option either.

Is there some kind of solution for the BIOS recognicing the 4GB? Or is it impossible in this MoBo?

Thanks in advance

Thanks Fernando,

If you are almost sure that it is true, it must be true... and that is my perdition ;)

Some caritative soul reading this thread, can give any solution, or link to a modded BIOS? Maybe there is a compatible BIOS from another MoBo
