Hi everybody. I'm new to the X48 platform and need some help pushing from 3.6 to 4 ghz
A bit of my background:
(Former) board in main system evga 780i/780i FTW. Went thru every possible combination of failures with that p.o.s (from DOA to ethernet failure to video corruption, you name it), 7 replacements total over 1.5 years! I finally gave in to the myriad of problems with the nvidia 780i chipset (they have no business making motherboards)
, bit the bullet, got rid of my 2 8800 GTs and bought this fine board at the egg just before it went OOS.
Standby system: e8400 0.c to 4 ghz in a ga g31m es2l, 4 gb ddr2 1066 reapers, running raid 0 on a 300 w psu in a SFF case I like to think of as an oversized laptop
With that introduction, onto my problem:
I have pushed this fine specimen to 400 fsb on a Q9650/8gb ddr2 800, 1:1 and 5-4-4-15 2T, with just slight bump in board voltages, cpu core at 1.325v. Rock satable. My problem is I can't go any further. No matter what I try. The board will just not boot up at 1800 fsb, and the lcd readout stops at the checking memory stage. These are the o.c parameters I have tried. I have 8 gb of the nvidia sli ready memory running at ddr2 800, have also tried a 4 gb kit of the 1066 reapers, but even those will not o.c to 1066, but will only underclock at 800.
For 1800 fsb/4.05 ghz
NB 1.41v (gone upto 1.51)
FSB Term 1.30v
S.B 1.5v 1.50 to 1.55v
CPU GTLVref 0.65
NB GTLVref 0.67
DRAM Static Read control - Disabled
AI Clock Twister - tried everything upto Strong
AI Transaction Booster - Manual
Loadline - Disabled
CPU clock Skew Normal and 100ps
NB Clock Skew - Normal and 100ps
Ram (Strap 333 and 400)
I am running 8 gb of the nvidia SLI ready series (ddr2 800 5-4-4-15). I know they are stable to 900 mhz, because I had reached 1800 fsb on the 780i platform running 1:1. It seems like this board just does not like to overclock OCZ memory, or maybe the 0902 bios is pretty stringent in terms of memory?
I see some sig/s running a Q9650 at 1.325v and boy am I jealous!
AI Clock Twister to Auto
AI Transaction Booster to Auto
Running at 1800 fsb with cpu at 1.3625v.
I'll need to dial it in now, take me a week, 10 days. How are my board voltages tho? The bios shows all voltages in green. Am I safe?Edited by c0re2 - 11/18/09 at 3:58pm
