I just installed the combo memory indicated in the header and I am having some difficulties. To be able to get the job without having to restart the computer itself I put the sticks in DIMM slots 2 and 4. When I ran Windows 7 x 64, install with the BIOS settings to "Optimized" It crashed just after the loading screen with the Windows logo. "Fail-Safe" gives the same result. I checked each stick individually in the slot with two-memory test and spent two fines without error. There are too many errors to count when both sticks are independent of the BIOS settings. The following settings are BIOS, which allowed the installation to finish. Many of which are a compilation of parameters in the messages I found on this site for similar combinations of memory. I only had one stick of RAM installed in order to get there btw.
I am now able to start Windows and have install the second stick. It seems to work slowly and gives the opportunity of a blue screen crash me or stops responding on the desktop. Any ideas on making this stable would be much appreciated. In addition, the stock clock speed of 333, the RAM is 1066 compared to 1100 and CPU-Z shows my ratio FSB / DRAM 5:8. I think this setting should be changed. I just want it to be stable at stock settings before you start overclocking.
System specification are as follows:
Motherboard: Model: GA-EP45-UD3P Rev#: 1.6 Bios Version: FE
CPU is Q9400
RAM is F2-8800CL5D-4GBPI
Power Supply is Dell 750W Power Supply - DW002 / H750E-01
BIOS specification and other settings are given in the attachment file.
If you want to ask any further information you can I will be happy to provide it.
