Getting G.Skill to work with Crucial

[thefi3nd]

Motherboard: Gigabyte EP45-UD3L Rev 1.0
RAM: F2-8500CL5D-4GBPK (2Gx2)
CPU: Intel? Core?2 Quad Processor Q9550

I just got the gskill ram in the mail today and tried to put it in with my current Crucial BL2KIT12864AA106A. They're the same speed, timings, and voltage ratings. I've also flashed the latest F9 BIOS. With all 4 sticks together, the computer won't load past "starting windows". With one gskill and one crucial, it won't get past the initial boot screen. Also for some reason the BIOS changes the timing to 5-7-7-24 when trying to use with the crucial even though it is all 5-5-5-15. Any help would be appreciated. Thanks.

The different sets prob don't mesh well, try it with the GSkill sticks in slots 1-3 and the Crucial in 2-4, set the timings to 5-5-5-15 manually, set the DRAM voltage to 2.05 and since I'm not sure what your NB is set at raise it .05...then give it a try.
