Hello all. This is a very informatve board but I still have questions.
I have an old Gigabyte GA-P35-DS3L with an E8400, 3GHz, processor.

I purchased two sets of F2-8500CL5D-4GBPI-B for 8 gigs of memory. 2 sets of (2x2GB)
http://www.newegg.com/Product/Produc...82E16820231246
Since this computer still runs so well I decided to get a few more years out of it with more memory and 64 bit Windows 7.
The F-8 bios recognizes te memory correctly at 1066MHz at 2.1 volts. I loaded 4 gigs and installed Win 7 and then installed the second set for 8gigs. This is when the problems started. Since I have been lurking and searching the board this was not unexpected.
As per previous advise to others I set the parameters to 800MHz Cas latency 4 with optimum settings of 4-4-4-10.
Act to Act tRRD 3
Write to read delay tWTR 3
Write to precharge delay tWR 6
Refresh to act delay tRFC 40
Read to precharge delay tRTP 3
Static t read 5
Static to read Auto
Setup like this programs and windows open very fast and absolutely no memory erros using Memtest 86+ and Windows 7 memory diagnostic test. I have found the windows memory test very useful as a predictor of problems running the operating system.
Trying to run 8 gigs of memory at 1066MHz was a problem at first until I upped the FSB voltage .2, MCH voltage .3 and the memory to .3 volts. Using 5-5-5-15 with:
Act to Act tRRD 4
Write to read delay tWTR 4
Write to precharge delay tWR 8
Refresh to act delay tRFC 68
Read to precharge delay tRTP 4
Static t read 6
Static to read Auto
The computer would finally boot and run at 1066MHz but would have hardware problems when running the windows 7 memory diagnostics. I set performance level to standard and tRFC to 88 and still would not pass window's diagnostic.
Any advise or insights I should be aware of other than run at Cas 4??? Mybe I should have run memtest86+ at 1066MHz before posting to see if there was a problem running this memory at 1066MHz. ???
