Talking [Team.AU] Corsair Dominators 2000GT C7 retail kit + EVGA Classified = magic

Hey fellas

I seem to be in this perpetual "testing" mode but i tell you what, I love it. Getting the end results is nice and all but getting to it is even more fun.
Always great to talk(&pick his brains) to my mate youngpro during these sessions :up: who is about to unleash a storm from downunder so watch out for that.
Good to always catch up with the usual suspects during benching you know who you are :

So in my preparation i've battling with the following components in intial stages

Test Configuration:
  • EVGA CLASSIFIED E760 (S610 bios)
  • Intel Core i7
  • 6GB 2000GT Corsair Dominators CAS7 DDR3 > Week 22, 2009
  • Asus 4870X2 Graphics Cards
  • 1000W HX1000 Corsair PSU
  • 1hp C-BuZz Single Stage (kayl evap)
  • 160GB IDE Hard Drive
  • Windows XP Pro 32bit SP3






excuse my non-fancy photochop skillz :




The purpose of all this testing i guess it to be able to at least get a rough idea what sort of settings i will have a chance to try on LN2 before i start going cold.
I like to pretest on SS to not waste LN2 i guess and i get to concentrate on what i'm doing a lot better than having to pour LN2 all the time.
Wasting money also makes no sense heheh :

My first concern was 2:10 RAM ratio. This ratio sucks on my Gigabyte X58-UD5.
I just couldn't get any decent clocks out of RAM past 1GHz with this ratio.
Why this ratio? Well i'm working with 25xmulti so i've got a couple of options here, to go to 2:8 CAS6 which is fine or 2:10 CAS7 which is better as i can max out the RAM as well at top clocks.
There is always the 23x multi as well which i will explore but i'll be battling BCLK here so why not start with easier setup first heheh

I'm hoping to be able to stabilise 32M SuperPi at 5.5GHz so I'll need to be able to run 220MHz bus stable right

OK so lets start there

220MHz bus stable with CAS7 2:10 RAM ratio running at 1100MHz 7-8-7-21-1T

Always start with the good old 32M SuperPi



What about 3DMARK01 >> some of the tests in 01 can be pretty taxing on system itself
can it handle , cars, lobbies, dragos >> YES IT CAN
(starting to sound like Obama )



what about 3DMARK06
no dramas sorry i'm just laughing at myself now :rofl:



If i needed say 5GHz + NB speed
can it handle that
hell yeah




Let's bump it up (for insurance puporses only) hehehe
224.4MHz bus stable with CAS7 2:10 RAM ratio running at 1122MHz 7-8-7-21-1T

hmmm 224.4 * 25 = 5610mhz grrrrrrrrrr fingers crossed hehehe

32M SuperPi = Done




AM3 can sometimes be a biatch with RAM going too hard
not here



3DMARK06 ... looks good



will it do 1132MHz 7-8-7-21-1T.........hell yeah but now i'm just getting greedy . i dont want to push more cause i'd be devastated if these modules died






This is all nice and dandy at -50C. Now i have to repeat this at -130C with 25x multi

Anyways i've still got plenty more testing ("fun") to do so i'll pop in if any updates occur




If you'd like to try my settings i've got the bios template attached :up:

Awesome stuff Dino..

Yes the journey and adventure in testing stage to reach the end result is always fun (when everything falls into place of course)

Excellent 32M Pi efficiency there too

Excellent results Dinos. That board seems to provide the flexibility for benchers needing high bclk and lower multi as well as lower bclk and higher multi, while maxing out the ram.

hey guys
thanks
this board is pretty versatile for sure

fingers crossed i am able to improve my LN2 clocks since last bench on GIga UD5

246.4MHz bus is ok
i can bench 1M but 8M wont go past first loop

i dont really need to push more here even if i wanted to use 23x

hehehe

Sweet clocks there Dino, but you never know when you need more bclk for 5.7+ ghz hehe
