b0redom Posted May 6, 2006 Posted May 6, 2006 Hi all, I've got a NF4 Sli Ultra-DR Expert mobo. I've just bought a pair of Corsair TwinX DDR, PC3200 (400), 184 Pin, Non-ECC Unbuffered , CAS 2-3-3-6 RAM sticks to put into it - to make a total of 4. With any combination of 2 (in the orange slots), the mobo fires up fine. If I add the other two, the mobo seems to freeze on 3 LEDs. Anyone got any ideas?

KimTjik Posted May 6, 2006 Posted May 6, 2006 Before you put in all modules what have you set "Command Per Clock" (CPC) to in "Genie Bios", disable (2T) or enable (1T)? Disable it and look through your settings to make sure they're not very tight. You could need some extra "space" to get the system running all four.

Voltes-5 Posted May 6, 2006 Posted May 6, 2006 Disable CPC, and set the dram at 166 divider for now instead of auto. Here's my OCDB entry, I know its not the same ram but its just to give you some ideas where to go. http://www.dfi-street.com/forum/showpost.p...4&postcount=197 Share this post Link to post Share on other sites More sharing options...
b0redom Posted May 6, 2006 Posted May 6, 2006 Ok, set CPC disabled, set divider to (5/6) 166. Still no joy getting the thing to boot. Any other ideas? Cheers... Tom Share this post Link to post Share on other sites More sharing options...
b0redom Posted May 6, 2006 Posted May 6, 2006 Update: I also loosened the timings and bumped the RAM volts a little bit - still nothing. I don't even get a BIOS screen. Any ideas? Tom Share this post Link to post Share on other sites More sharing options...
boatasiaus Posted May 6, 2006 Posted May 6, 2006 do all 4 sticks have the same SPD settings? Share this post Link to post Share on other sites More sharing options...
b0redom Posted May 6, 2006 Posted May 6, 2006 I believe so, they're the same mfr and the specs all look the same. In addition, I can use an old one and a new one together with no problems. Tom Share this post Link to post Share on other sites More sharing options...
ICON57 Posted May 6, 2006 Posted May 6, 2006 make sure you are not overvlocked....do a bios clear, load optimzed settings...with just the 2 sticks, then try adding the others sticks...if you do boot,, go back into bios, and load optimized settings again.

seufari Posted May 6, 2006 Posted May 6, 2006 does it boot with one stick? Two sticks in the orang slot? Share this post Link to post Share on other sites More sharing options...
b0redom Posted May 7, 2006 Posted May 7, 2006 Yep, as I said - I tried 1 stick and 2 sticks in the orange slots. I also tried diffent combinations of sticks in the orange slots and all seem to work correctly, however when I add another, so I have either 3 (in any yellow slot) or 4 (in all slots) it refuses to POST.

Tom These boards don't take 3 modules of memory: 1, 2 or 4 nothing else. Still it doesn't help you since you want 4 modules to work.
