Six months ago i bought a pi black 1100mhz ddr2 mem kit.As i could'nt manage to get it running over 800mhz without getting a BSOD, after some minutes of gamming, i returned the memory to the vendor and asked for another model, the F2-8500CL5D-4GBPI-B.
For my surprise this one didnt work either. I sent an email to the g-skill's tech suport and opened a post on this forum. After alot of discussion the Gskill tech told me it was probably my cpu's fault (C2D e4500) since it's FSB was way too low and the memory kit needed at least a cpu with 1066 fsb in order to work propely, so i lowered the memory clock to 667 and used it this way for some months untill i had the money to buy a new cpu.
One week ago i bought a C2Q Q9450 which has the adequate fsb but I STILL get the same BSOD after some minutes, sometimes some hours, of gameplay, so i would like to ask whats going on? I mean i've tried all the recomended configs on the bios like voltage, timings, etc and i still cant get this memory to work at the rated speed with stability.
Is my mother board REALLY compatible with any gskill memory module?I know this mobo had a lot of memory compatibility problems on the past but the lastest bios was supposed to fix these problems.
I will post my current specs following, but i wont post my full bios settings unless it is really nescesasry, beacuase i have messed arround with them alot with no success at all.
CPU: Q9450 @3.2
RAM: F2-8500CL5D-4GBPI-B (4GB)
GPU: ATI 4870 1GB
MOBO: Ga ep43 ds3l BIOS REV 1.0 (F9e lastest one)
PSU: AKASA 500W 80% efficiency, version 2.3, 2x20A 2x12v rails, 2x6pin connectors.
HDD: 2X Seagate barracuda
OS: W7 64bits
some things ive already tried:
mobo mem slots 1-3, 2-4
1-3 does'nt boot.
2-4 works.

MCH - set to 400 at this moment. @1066, 1:1 ratio
CPU FSB - set to 400x8 atm. @3.2 mhz
pci-e clock 100
cpu clock dv 800 (default)
pci clock dv 800,900 (900 atm)
cpu shew 0,50, 150 (50 atm)
mch skew 0,150,200,250 (150 atm)
Voltages:
cpu ppl 1.55.
mch voltage - 1.1,1.2,1.3,1.4 (currently set to 1.3).
Cpu vcore - 1.25,1.275,1.3,1.325,1.35 (currently set to 1.3)
Cpu ter - 1.2,1.3(currently set to 1.3 i believe)
memory voltage - 1.8,1.9,2.0,2.1 (currently set to 2.0)
ich - auto
cpu ref - auto
Timmings:
5,5,5,15 ; 8,8,8,20 (5,5,5,15 atm, i used the other set of timmings only once to see what happened, it didnt fix the problem tho)
trrd - 3,4 (4 atm)
twtr - 3,4,5,6 (4 atm)
twr - 4,5,6 (6 atm)
trfc - 52,64,68,72 (testing 72 atm)
