Black screen on Pavilion m9150f upgraded to 8 GB on 64 bit PCs

[Norwester]

Hello Support,

My upgraded Pavilion m9150f with Intel Core Duo E6700 Dual-Core Processor 2.6 GHz 4M L2 Cache LGA 775 and Windows 8.1 64-bit OS works fine with the original 3GB RAM installed:

2X SAMSUNG 512MB 1RX8 PC2-5300U-555-12-ZZ

2X SAMSUNG 1GB 1RX8 PC2-5300U-555-12-ZZ

However, despite this computer's specifications (see below), startup returns a black screen with 8GB RAM installed:

4X KOMPUTER BAY 2GB PC2-6400 DDR2 800MHZ NON ECC LD UNBUFFERED

BIOS was updated prior to CPU upgrade.

Power supply MAX OUTPUT is 350w. 

Please advise.

Thank you!

Hi,

The below charts are for the Bencia motherboard which is installed in your PC. The quad processor has 1066 FSB.

Hello banhien,

Yes, the Crucial RAM functions as expected ...

Is there an explanation why the Komputerbay memory is incompatible?

Thanks again!
