2X 7800GTX SLI 1st results with stock cooler.. I'm impressed :)

[Pedro Rocha]

Here it is the very first with 2 Gigabyte in SLI - stock cooler of course and still using my good old FX-55 (0.13WR) at around 3.3500Mhz ..Redline using only 3.2.v ..cooling: silent 404a Mach 2..

1st - Driver instalation if you have one card already installed you have to boot on VGA mode - uninstall drivers - reinstall - than enable SLI

2nd - Even with 2 card in SLI the stocker is very silent - almost inaudible..

3rd - OC, a plesant surprise - I discover the SLI is the best of the 2 card if you forced OC with coolbits or RivaTuner..
The first card gives me 526-1390 on single, the 2nd 512-1360 - SLI OC = 526-1380 - well done Nvidia and improvement from 6800 Series (SLI OC gives you the worst of 2)

Here is a photo:


3DMark 2005 :

Top 8 on Hall on Fame on the very first run - not bad at all


3DMark 2003 :

But I can not publish this score
Is there any bug with 30.000+ scores tha dont let publish??

And finally 3DMark2001

This score is nothing special, because I'm using a non-tweaked WindowsXP..

I have to work on WindowsXP tweaks (do a testing of some tweak it may boost 3dmark scores), before cards go to Ricky's cascade ..

This is just to share with you my first 1/2 hour bench session with 7800GTX .. I can say I'm really impressed with performance of this cards at stocks..

This is Pedro Rocha over and out

It is good to see these fine cards in your hands. I hope you have great results with then. [[ ]]

ron, i'm working on a sli cascade, it will be 1 1st stage and 2 2nd stages 3 compressors, each 2nd stage can be turned independent i wish it works good, we need to discuss some ideias msn!!

Can't wait to see you guys back in action again

[makatee]

Hello Pedro!

Nice Scores, 3dmk03 have BUGS......not publish score over 30k...

[metro.cl]

nice pedro you are the only one i can trust on 3dmark benching, you run all of 3dmarks, hope you can destroy some wr.


also please tell the new tweaks i can wait one month or so for you to release them (please), so you can have all the glory at first (not saying i could beat you, others that have top equipment may if you tell them the new tweaks).

go portugal

wow nice so that's 525+40 geometric = 565mhz core right ?

[Kanavit]

wow, you took Macci's highest score with crossfire down easily with SLI. congrats Pedro, keep us posted! :p

you cant compare those 2. You should compare 7800 in SLI with x900 in crossfire

[Pedro Rocha]

Well, 45K not dificult to achieve with stock coolers..

This with just one tweak on WinXP, but lobbys and car much more lower than a single 7800GTX on my tweaked Win2000 bench disk partition

I didint even change the jumper to 5v, so Mushkin Redline only ata 256Mhz 2-2-2 with 3.2v

My goal seems achievable, but all depends of the behaviour of these 2 cards in Ricky's new SLI cascade

Yes. set at 526Mhz at drivers (coolbits), 3DMark 2005 reads :
- Core Clock 567 MHz
- Memory Clock 1386 MHz

OK, here is a comparison between;
- 2 7800GTX SLI in WindowsXP (with just 1 simple tweak)
- 1 7800GTX Single in Win2000 (my fully tweaked Win2K partition):

CPU and mem speeds more or less the same ..(3350 / 256)



Those Lobbys and CH depressing low

I wish Win2000 supports SLI

Have to work on other tweaks for WinXP, the one I used seems to give better results with 2005 than 2001 ..

How cold is the cascade? I don't think many cards have gotten past -50 to -60c.

maybe you should try to find a tweak that allows you to run sli in win2000
