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

[eva2000]

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

Sweet George! Nice stuff. Are you able to break 600 MHz barrier

I love your scrupulous tests!

[SeLecT]

Nice test!

Can you bench with 600Mhz?

[EnJoY]

Nice George. Did you test with other timings or voltages?

Powerchip IC's I assume?

Thanks guys, literally only had the kit installed on board for a few hours so haven't done much testing as yet. Memtest86+ v2.01 so far to 595mhz 5-5-5-15 at 2.10v with 1.517v NB is where the ceiling is, so need to tweak away at voltages and clock fine delay values to see if I can push 600mhz 5-5-5-15

Haven't tested any other timings of voltages yet - still alot to test

Yup from Corsair forum's IC inquiry thread they're PSC - Powerchip ICs

[-n7-]

Sweet.

Thanx for using HCI, & please keep doing so

Determines stability much better than anything else for RAM (& NB).

[eva2000]

Updated 2nd post with 595Mhz 5-5-5-15 super Pi 32M

[makaka]

i love those Corsair clock . My crappy Geil PC 6400 cap out @ 500-520 with 5-5-5-15 no matter what voltage (tried even 2.6-2.7v )

[REBEL900]

Nice scores EVA

[dinos22]

lol nice RAM mate

mine OC the same on Gigabyte X38-DQ6 :thumb:

[eva2000]

Thanks guys

[The0men]

Is there anything to gain beyond 2.25v??

I've not played with powerchips much, I was wondering if they react to voltage like D9,
(except the part that new d9 mostly die beyond 2.4v 24/7 use)
Or if there is only pain and no gain beyond the voltage you have used?

Thanks for the testing, anf thats a nice frequency for low voltage RAM.


EDIT: 4GBs! thats excellent, I guess theres little point adding more volts, did not realise it was a 4GB kit.

[saaya]

from my experience powerchips dont scale well with high vdimm, unfortunately... if they would, then they could outperform micron chips!
powerchip chips are good for high cas5 and cas4 with low vdimm.
they do scale until higher vdimm than most other chips... but they dont scale much and stop scaling around 2.2v
Ask miravo, hes like a powerchip expert the best batches scale up until 2.3v, some only scale up to 2v iirc.

[eva2000]

Honestly, haven't tried beyond 2.23v vdimm so not sure but from what I done so far you can see it doesn't scale much i.e. 585mhz 5-5-5-15 at 2.1v then 595mhz 5-5-5-15 at 2.23v, only 10mhz more so I'd say doesn't scale that well (not comparing to micron D9GMH/D9GKX).

Also remember it depends on what you're testing - you definitely need more vdimm for folks testing speeds with dual or quad super pi 32m instances compared to someone testing single super pi 1m and 2m passes or folks using quad core vs dual core cpus

[Spyrus]

I cannot push mine 2x2GB Evo Past 580 with ease.
What have changed there besides tRFC that i see that is 60?
Any extra third timing?Or skews?

[dinos22]

tRFC is the main timing for higher frequency
loosen it up and you will push past 580

Thank your for answers.

Yer not much to gain after that 2.1v.

Pity there is nothing that scales like micron, but clocks so well on low clocks.

I guess you are right Saaya, they would sure beat micron if they continued you to scale to 2.4v or beyond.

But still they have their use, for a 4GB kit that you could run at 560, stable at such low voltage, would be cool and good for a quiet system with vista or something.

[saaya]

yeah, thats what promos is really good at... at low vdimm its really really nice.
and you can get high densities with them too.
and its cheap... the only problems are, it doesnt work for high end memory, and they have a history of delivering bad quality chips that die after some time...

Here, i made this test a long time ago evaluating powerchip:

Red=micron
Green=elpida


as you can see they are outstanding for low vdimm cas4.
but unfortunately they almost dont scale with vdimm at all..

[The0men]

Very good for CAS 4 indeed.

I assume that because its so good at low voltage then yer, can have high densities
Plus some chipsets wont take 4GB or more up very high frequency anyway
making it ideal for systems needing loads of memory.

saya as for reliability
would you say powerchips last longer or a good set of d9gmh or d9gkx
or is it too early to tell?

nice set of stix eva2000

They actually do walk all over any 128MB ICs that Micron has out.

thanks seem to oc'd the same as dinos' set as well - they're exact same batch AFAIK
