2GB and higher forumsFor for all discussions related to DDR1/DDR2 AMD and Intel memory configurations >2GB in size. Share your settings and experiences regardless of brand.
Binned for both Nvidia and Intel chipsets. I prefer using Intel chipsets as they are a lot more efficient on DDR2 platform...........DDR3 platform is different however where 790i rules them all
Test Configuration:
Gigabyte X38-DQ6 (F9a bios) STOCK BOARD NO MODS
Intel Core2 Duo E7300 CPU
4GB DDR2 PC9136 Corsair Dominators
Gigabyte 9800GX2 Graphics Card
620W Corsair PSU
TT BigTyphoon Cooling CPU
160GB IDE Hard Drive
Windows XP Pro 32bit SP3
STOCK SPEED 32M SuperPi to warm up a little
I've used 2.08vdimm to test max stable frequency
>>>> 596MHz stable with superpi and 3D <<<<
GOAL >> SHOOT FOR 600MHz MARK
non-Micron ICs have shown a tendency to not scale well with voltage. I've seen this during my testing as well as bumpin the RAM to 2.13v only gave me a semi stable 600MHz even with relaxed tRFC (btw this timing will gain stability with high capacity RAM >> performance toll is insignificant as well )
Well time to bump vdimm some more (unfortunately vdimm jumps on this particular Gigabyte board are fairly big +0.05v which sometimes doesn't help with volt sensitive RAM >> new gen motherboards coming out VERY soon have this fixed with incredibly small volt jumps :up
Did a quick test with this Gigabyte 9800GX2
783-1944-1188 stock card '01 Nature stable
LN2 runs on CPU and air OCs on this GFX coming up soon
CPU is not too shabby either for a value chip
i found the trick to high FSB on this CPU and board is to use the new F9a bios (older one was limited to 380MHz FSB ) and also to use GTL Ref +3% and second one on NORMAL for about 520MHz benchable FSB
well it seems eva got pretty much the same results on different hardware and his kit
pretty sweet RAM for sure...i wonder how they would overclock in 8GB config (4x2GB though)...pretty sure this Gigabyte X38 will not have issues pushing some serious clocks with 4x sticks as i've benched my Corsair PC10000 dominators pretty high with 4xsticks and 4-4-4-x latency
