having issues with my new ram( F2-8500cl5d-4gbpi-b)

[rollingonall4]

dumped my prior ram for some Gskills and apparently i can only get them to work together at 800 and not 1066. by them selves they will run 1066, but when paired, only 800, If i manually set it at 1066, bsod at log in screen.

My current set up

MoBo: Asus P5Q SE Plus
CPU: Intel Core 2 Quad Q8200
Ram: F2-8500cl5d-4gbpi-b

I can try to post pics of bios soon.

Hope someone can help

ok, did changes and as soon as i log in, it blue screens, any other ideas?

edit: ran mem test and it failed

[rollingonall4]

ok, update, woke up this morning and memtest each memory in single mode. both passed all the way with not errors, so atleast we know ram is not faulty...i just don't get why they are not stable when paired

Change the NB Voltage back to AUTO

Row Refresh Cycle Time 68

Leave RAS# to RAS# Delay AUTO

Write Recovery Time should be 8

Do you have the latest BIOS?

Thank you

thanks for the reply, but already resolved it, seems ram slot A1 is faulty at 1066 mhz, ended up running them on slot A2/B2.

Glad to see you got them going, sorry about the bad slot
