Hello I bought 2 kits of F2 8500 CL5D 4GBPK, each consisting of 2 sticks of 2 GB.
I'll call one "old" - bought 4 months ago
I'll call the other one "new" - bought last week.
the old kit is working fine at 1066 MHz on the EP45-DS4 and a Q6600 overclocked to 3.5 GHz (FSB 389 MHz).
the new kit is not working on this mother board at 1066 MHz. But it works at 778 MHz (389 * 2). This new kit is also working on an other mother board (P35-DQ6) at 1066 MHz.
When I set the 2 kits on the EP45-DS4 to get 8 GB, it does not work
- with the 2 kits at 778 MHz, I pass the post/BIOS. but the windows 7 boot fails
- with the 2 kits at 1066 MHz, I do not even pass the post/BIOS. the mother board bips indefinitely.
Here some details on my configuration: MCH & ICH core are at 1.2V (read elsewhere on this forum). I've also set the DRAM voltage to 2.1V. These settings do not change the behavior of the new kit.
I've already returned the new kit to my reseller who provided me a new one.
I was to forget... I tried the 4 memory slots of the mother board with a 2x2GB kit along with a 2x1GB kit (same specs 8500, CL5D).
I am really lost here. Help is welcome.
My objective is to have 8 GB on the mother board.
