4GB Corsair PC2-9136C5DF + DFI LT X38-T2R 1/11

04:19 AM

Thanks to Corsair folks, I have the opportunity to take a pair of 2x2GB Corsair PC2-9136 Dominator (TWIN2X4096-9136C5DF) dual channel kit for a test drive

Rated Specifications:

2x 2048MB matched CM2X2048-9136C5D modules
571Mhz or DDR2-1142MHz 5-5-5-15 2T
2.1v
SPD: JEDEC standard 5-5-5-18 values at 800MHz
SPD: EPP standard 5-5-5-15, 2.1V values

The 4GB Corsair PC2-9136 Dominator kit was tested and validated in Corsair's labs using an eVGA 680i SLI nvidia chipset motherboard (P32 bios) and comes with the Corsair Dominator Airflow fan which consists of 3x40mm fans just like the Corsair Dominator PC2-10000C5DF kit.

Viewing Corsair's latest IC inquiry thread listing of ICs, most of Corsair's product lines have transitioned to PSC - powerchip ICs and the 4GB Corsair PC2-9136 Dominators are no exception

System specs

Intel Core 2 Extreme QX9650 L739A640
Thermalright Ultra 120 Extreme + 120x38mm Panaflo 103cfm (MX-2 TIM)
DFI LP LT P38-T2R 1/11 Official bios
128MB Gainward FX5200 PCI
2x2GB Corsair PC2-9136C5DF Dominator dual channel kit (dimm 1+3 slots)
750GB Samsung HD753LJ
Pioneer DVD-RW
620W Corsair HX620
WinXP Pro SP2

Results:

Everest Ultimate SPD settings for modules - looks like week 12, 2008 made with a week 13 packaging date on module's Dominator heatsink label - 08130508 v1.1

I've started testing on DFI LT X38-T2R motherboard with 1/11 official bios and they overclock very easily just by setting memory to 571Mhz 5-5-5-15 and vdimm to 2.10v I was already booting and memtest86+ v2.01 stable!

@585Mhz 5-5-5-15 2.10v

Quick jump to 585Mhz 5-5-5-15 at 2.10v still was easily quad Super Pi 32M stable (hyperpi v0.99 gui wrapper) and single Super Pi 32M stable

4GB Corsair PC3-9136C5DF @610Mhz 5-5-5-15 at 2.23v

Using setFSB from 595Mhz 5-5-5-15 at 2.23v in windows I slowly pushed the FSB and thus the memory clocks to 610Mhz 5-5-5-15 at 2.23v for max validation

lol nice RAM mate

mine OC the same on Gigabyte X38-DQ6

06-05-2008, 08:27 PM #4 (**permalink**)

Yeah saw that very similar in terms of oc'ing both on X38 boards, just mine needed more vdimm for 595mhz maybe due to tighter strap/divider (2:3 vs 5:6) and timings and PL used ?

Which of Corsair Dominator PC8500 2x2GB and Crucial Ballistix Tracer RED PC6400 do you think can reach highest frequency on CL5? I'm using an AMD AM2 system and M2N32-SLI or DKA790GX.

Welcome... probably best if you posted in AMD DDR2 for non-related question

I'll move your post there after you have a chance to read this reply

I haven't used AM2 system so no idea, for Intel system you'd have a better chance with Crucial IF they're the new 80A revision 2x2GB Crucial Ballistix PC2-6400 new IC revisions are here and not the 804 revision. The Corsair Dominator would be better than old 804 revision crucials.
