Pegatron M2N78-LA mobo memory

[pjthedj]

Thinking about getting an HP P6310 desktop that uses the Pegatron M2N78-LA mobo.
In another thread here I saw posting for user manual for this board but have no idea where it came from. There is no manufacturer identification anywhere that I could see. It lists that it can use DDR2-667 memory. But the HP site for this computer says it uses DDR3-10600 memory. Does anyone know why the discrepancy? Board revision? Documentation error?

Thanks in advance,

PJ

Most motherboards can handle a rage of memory speeds. Even when a motherboard supports up to a certain speed, it it likely it can handle a higher speed by throttling the memory down to a speed the motherboard can handle. I hope that helps.

Actually, HP seems to use several different versions of the M2N78-LA motherboard (the 'Viola', 'Violet', 'Violet2', 'Violet3'). Some use DDR2 memory (like mine), some use DDR3. And apparently, there are different sockets in use....

I discovered this little issue myself on my hp s5260f w/a M2N78-LA Violet6 6.01 motherboard... seems its an AMD CPU known problem; Errata 379.

from HP specs:
Dual channel memory architecture
Four DDR3 DIMM (240-pin) sockets
Supported DIMM types:
PC3-10600 (DDR3-1333)
PC3-8500 (DDR3-1066)
Non-ECC memory only, unbuffered
Supports 4GB DDR3 DIMMs
Supports up to 16 GB on 64-bit PCs
Supports up to 4 GB* on 32-bit PCs

NOTE: * 32-bit operating PCs cannot address a full 4.0 GB of memory.Due to AMD limitation, DDR3-1333 modules will run at 1066 MHz if three or more modules are installed.

AMD lists CPU revs RB-C2, BL-C2, DA-C2 with this prob; and of course CPU-Z shows I have RB-C2... 667 memory running @533mhz.!

hokey hp... gives me 2x1gb samsung, and 2x2gb elpida memory...

so does anyone know what voltage ram to get for this mobo? i'm seeing 1.5-2.2 volt ddr3 1066/1333 listed on newegg...
