I crash in OCCT blended after ~5 minutes with transbooster disabled and relaxed 1.
I am stable at the following settings in OCCT:
FSB Strap 333
FSB 423x8
DDR2-1016
5-5-5-15
VDIMM 2.35 in BIOS (these sticks can go up to 2.5!)
trans booster disabled 2
AI Clock Twister strong

This KILLS bandwidth.......it could be that these Geil sticks have the SPD TRFC as 52....
I am also stable at
FSB Strap 400
FSB 423x8
DDR2-1128
5-5-5-15
VDIMM 2.35 in BIOS (these sticks can go up to 2.5!)
trans booster disabled 2
AI Clock Twister strong

I am going to test these frequencies with trans booster set to 1 and clock twister set to light.....fingers crossed. Hopefully this will help with the bandwidth.
