Corsair GTX 2 testing stage 1 X58 chipset

[chew*]

Lets have a look at the modules





So first I'd like to state that i'm preety much a nub to intel so I'm gonna keep it simple play with primary timings and see what these can do through a range of speeds.
Second I'd like to state no B2B tricks here.

The System
Intel core I7 920 DO
Corsair dominator GTX 2 3x2g CL8 2250mhz
Gigabyte EX58-UD3R
misc vidcard
Win 7 ultimate no tweaks
Custom watercooling

First up Cas 6

6-6-6 1800 1.65v


6-6-6 1840 1.665v


6-6-6 1850 1.71v


6-6-6 1872 1.76v


6-7-6 1880 1.71v


7-7-6 1900 1.71v


7-7-6 1950 1.71v


7-7-6 2000 1.71v


7-7-7 2050 1.71v


7-8-7 2100 1.71v


8-8-7 2150 1.665v


8-8-8 2200 1.665v


That concludes water testing. Unfortunately I was not able to acchive spec but that isn't corsairs fault. As you will see in stage 2 they can do spec very easily and the cpu is to blame and needs cold to scale further. I might add that while i left voltage at 1.712 for most of those runs it obviously was not necessary for the majority I just found it easier to leave voltage at what i felt was a safe operating level.

7-7-6 2100 1.712v


7-7-7 2150 1.728v


7-8-7 2200 1.728v


8-8-8 2350 1.665v
I was just fooling with my uncore on this one


8-8-8 2400 1.712v


That wraps it up folks, as you can see these sticks can do spec and quite a bit more. Unfortunately they won't pull spec on most cpu's due to uncore limitations at XX temps.
The sticks certainly live up to there hype and get an A+ reccomendation for the hardcore benchers that must have absolute performance under cold temp ranges.
Be sure to tune back in to Stage 2 when I test potential on P55 platform

P55 testing
Usual disclaimer blah blah blah
I'd like to state that i'm preety much a nub to intel so I'm gonna keep it simple play with primary timings and see what these can do through a range of speeds.
Second I'd like to state no B2B tricks here.

The System
Intel core I7 860 from hell
Corsair dominator GTX 2 2x2g CL8 2250mhz
Gigabyte P55-UD4P
Gigabyte 5870SOC
Win Xp mild tweaks ( LSC + theme )
Air cooled mehalems something or other heatsink with taped on fan because megahalems wants you to purchase the fan clips for wider fans. ( not as long as I have tape )






*Disclaimer* this cpu is horrible and has some issues and some slight burnage so if I ran clocks low it's due to cpu not capable and not the rams faults.

1800 6-6-6 1.65v


1840 6-6-6 1.71v


1900 6-7-6 1.71v


2000 7-7-7 1.65v


2100 7-7-7 1.65v


2160 7-7-7 1.69v


2280 8-8-7 1.69v


I didn't bother with 8-8-8 seeing as 8-8-7 already surpassed spec and I hit what appeared to be the IMC limit on air.

Now just wanted to show there plenty of room for squeezing more performance and tighter timings however I like to show results that average users can acchive. That said YRMV with tighter timings.

Now this cpu is a complete turd so excuse the low clocks. Yes I tried with high clocks. Yes I tried to fry cpu with voltage. Yah preety much tried everything, can't polish a turd so here goes where we left off on air.



2300 8-8-7


2350 8-8-7


2400 8-8-8



After that I played with some effeciency testing and sadly I could not get the uncore/ram speed/timings I wanted without losing a severe amount of cpu speed so I ran these 2 runs.





After doing that testing I had just enough DI left for one run so I fired up my 32m Bench OS and let it rip tuned, wasn't to happy about effeciency but ehh what can you do.



That wraps up P55 testing. It was nice to acchieve rated specs on air but I'm not to thrilled with lynfield performance. The GTX2 once again lived up to specs and then some so A+ for that.
Sadly this chip was not up to the task for anything beyond 2400 ram. Thuban testing is up next be sure to tune back in

[chew*]

Reserved Stage 3 AMD

[zalbard]

Great numbers, chew*!
Any idea what chips are these?
And I have a feeling P55 platform will reveal their true potential!

[Don_Dan]

Nice tests Brian!

Are you memtesting before you enter Windows or do you use 32M as the only stability test?

Any idea what chips are these?

Elpida Hyper of course...

[chew*]

Memtest before boot.

Not tuning with cpu tweaker it's just there to show what I have set, preety much a bios guy myself.

I'm guessing they are hypers.

[FatAlbert]

waiting for stage 3 as it's more important than first and second

[M.Beier]

I fully agree with you Chew, I had same experience with Tylersburg, only, my IMC was even worse....
Will you use Thuban for stage 3?

[Gunslinger]

Nice, thorough testing, can't wait to see how Clarkbar performs with these.

[Oliver]

Hey man sweet write up , keep pushing it

These sticks are extremely strong and a pleassure to bench. They works and scale well with both CL6, CL7 and CL8
which are the area you most likely play them in. Clarkbar you migth wanna go CL5 if you have CORSAIR CMGTX2

[FlanK3r]

nice test Chew, waiting for next platforms

[chew*]

Just thought I'd toss this out there "unoficially".

As you can see there's quite a bit of untapped performance that I am not tuning for in the review. Subs can be tightened quite a bit more.

Air on gulftown / LSC + silver theme, no other tweaks.

[proxis]

well, they've really optimised CL6 on these sticks - otherwise there's no point in paying premium for gtx2 over "regular" 2000c7s ... cl7 is barely over spec of 2000c7, cl8 will be limited by the platform anyway

[chew*]

Hmmm I tend to disagree.....It took me 2 3x2g sets of regular GTX to make one "good" 2x2g bench set which I might add can't match these. Cost for my 2x2gig set was a tad more and i'm still short a stick for triple channel. 3rd sets the charm right

[FlanK3r]

stage2 and 3? ...when?

[chew*]

When I get back home. Far away atm.

[Leeghoofd]

Good stick there Brian, mine can't do TRFC 60 over +1000Mhz 32mb stable... needing 70ish level there and even 88 for 1100mhz... how you liking the REX III ? I'm more looking forward to Thuban stage :p

[Splave]

nice results, well worth $600 if you ask me. I love mine

was trfc on auto in the first couple SS's or did it require the bumps to maintain stability (100 to 102 to 104 etc)

[runnin17]

Waiting for stage 3. Woot.

[sponge bob]

waintig for the 890FX results ordered from Nichish 3x1gb cl8 2250 mhz Kit :P

[felix_w]

waiting for stage 3 as it's more important than first and second

Agreed...same for me too....

[Yellowbeard]

Nice work Chew, as noted, very thorough. And yes, the GTX2s are Hypers. GTX1s are PSCs, I don't recall specifically what rev.

[FlanK3r]

heh, i think, stage 3 will with Thuban

[youngpro]

dude, are you done making the rest of us look slack? you dont make any friends by doing things like this! relax man

[eva2000]

bloody awesome chew!

Nice work Chew, as noted, very thorough. And yes, the GTX2s are Hypers. GTX1s are PSCs, I don't recall specifically what rev.

So there's GTX2, GTX1 and GTX or GTX1 != GT ??
