G'day from Team.AU once again!

I received a retail kit of Corsair Dominator 4GB DDR2 PC9136 kit for torture the other day from their latest addition to high capacity DDR2 range.

RAM Specs: http://www.corsair.com/_datasheets/T...6-9136C5DF.pdf



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

RAM bump to 2.23vDIMM








Validation file (509MHz FSB; 611MHz RAM 5-5-5-15):

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

Very nice dinos the PC2-9136 of yours ended up pretty similar to mine in terms of oc'ing 4GB Corsair PC2-9136C5DF + DFI LT X38-T2R 1/11. Have you tried on 2:3 divider maybe ?

What vdimm used for max 610mhz validation ?

So the E7300 shows itself at last

dinos22

i didn't use that divider
i prefer performance on 5:6

but when i get a chance i'll test that as well

i used 2.23v for max screen

yeah 10xmulti and all man but FSB is a problem............on 965 chipset i cannot go past 490

eva2000

weird so while it has 10x, max cpu FSB is lower... sigh Intel is messing with us

dinos22

actually i've seen some CPUs with really good OCing so they should be just as good at their older brothers

dinos22

this CPU is no slouch

Miravo

Amazing set. I am jealous

dinos22

cheers mate

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
