2x WR with ATi AMD HD 3870 CrossFire

[northwood28]

Today afternoon, the Serbian Xtreme Team (animaN, BigJoe, CAR, Shiki and Spacemaster - administrator) with our guests: bojsa, d0minat0r and Northwood has broke the WR in 3D Mark 05 and 06 in HD 3870 CF class. We used the next setup:

ASUS MAXIMUS EXTREME (sponsored by ASUS)

2x ATi AMD HD 3870 (sponsored by AMD) @ 823/1260

Cooler Master Real Power PRO 1250W (sponsored by Cooler Master)

Intel Core 2 Extreme QX6850 (sponsored by INTEL) @ 4895.5 MHz (LN2 -125?C)[bOCZ Platinum DDR3 1800>[/b]> (sponsored by EuroLink Belgrade)

Damn, what am I doing wrong? I score just under 14K in 06 with 2x2900XT...

P5K = x16 and x4 links for Crossfire.

[northwood28]

setup pictures and video clips are on the SXT forum, so check them out ;)

feel free to ask anything that you may be interested in, I'll be glad to answer you...

I'll keep you updated with our next session! soon, very soon :D

penryn is comin'!

@Cephas: look at maximus extreme board, X38 chipset with 2* x16 lanes (CrossLinX) instead of x16/x4 on P35...

[Jason S. Global Moderator]

having (2) x16 lanes is good and all, but that's not what is shattering the WRs... it's the extremely heavy overclocking.

yup, you're right ;)

and tweaking the OS is also essential...

currently, we're waiting for new Penryns to come in Serbia and when we get them, it'll be party :D...

Woah! I didn't think even QX6850s could reach near 5GHz speeds. I can only imagine how hot the CPU would get running all four cores at that speed (but can also imagine how fast things would be too!!).

[Dinesh Malhotra]

thats really coool...... with all tweaking n OC`in.

i managed only 12,400 points on 3D mark 06 on my setup.

[northwood28]

stay tuned, we have more benchs to do next week ;)

[chconline Veteran]

lol 1.776V :p

[northwood28]

lol 1.776V :p

don't worry, we've done some sessions over 2V ;)

Well if you read it you'd be imagining how cold the cores are. -125 degrees

nice work dude. should keep an eye for liquid helium next time maybe :p

also isn't these new yorkfields able to hit 5GHz on just HSF no LN2 ?

ashame can't see what you could do with core 2 quad/extreme and CrossfireX 4 x 3870's lol

Good lord that is amazing.

What kind of OS tweaks are you doing?

I wonder what bench's you would get on Vista, see if it is worse

Anyone think it would be possible for me to get my E6850 at 4GHZ?

Possible since i have my E6600 at 3.5Ghz, i can't go further because of voltages.

Proper cooling and correct hardware, etc.. can do wonders.

yes, Yorkies have extreme OC potential and Wolfdales too ;) (can't speak about that cause NDA is still active :), but you can see all over the net how well they preform)...

wait, maybe we could do some CFX testing in future :D

@Garnett: really, there was no important tweaks at all :( but it will be next time :D

@mtber: you could push it to 4GHz with higher voltage and better cooling, but do you really need to go that high!? 3.5/3.6/3.8 is just fine...
