A beautiful site indeed. 500fsb 1:1 3-D stable w/SLI (official support coming soon) on the less expesive 965 chipset, although the Asus version has a "deluxe" price. What a great choice for mobo in a robust gaming system.

Yeah but the performance sucks... due to the 4x slot or old drivers maybe?

And I wouldn't hold your breath for SLI support on Intel 965/975...

And I wouldn't hold your breath for SLI support on Intel 965/975...Don't see any references to it outside of marketing/sales guys right now, but'll I'll keep looking for quotes that say more than "looking for more chance to cooperate". Nvidia locking out Intel (except when using a Nvidia chipsest) would seem to be short-sighted, hence my optimism. Hopefully 975x is on the table (http://www.digitimes.com/news/a20060727PR213.html)

Thanks for reminding me about the 4x lane though. That big slash of cold water woke me right up. Still looks like 975x and hacked drivers for the SLI.

I don't think it's because of the 2nd PCIe being "4x" only, but the limitation of the chipset. I am thinking the 4x lane came from the six(6) PCie x1 terminated at the SB instead of the 4x termination at the NB like the i955 (iirc). i975 have two(2) 8x PCIe lanes terminated at the NB so performance doesn't suffer as much like the pseudo secondary PCie x16 physical (4x electrical) lane.

18-19% gain...that's definitely not enough. Nice attempt though.

BTW, why did they make the 965 dual GPU capable in the first place? At least 2X8 would have been cool...Ill stick with 975X.

Sumanji

08-23-2006, 07:49 AM

Yeah, I would expect at least 50% gain minimum. After all you are paying 100% of the cost for having SLI!

Gigabyte DS4 + 6600@3.15Ghz + 350FSB + 2 x 7900GT + 2x512MB

3dmark05 - 15162

So we can safely say there has to be a bug here with the P5B , seems the lower clocked , limited fsb ,less ram , slower video cards wipes the floor with the P5B Sli Setup.

DS4 seems to be the board left out of the picture on xs.org :P

08-23-2006, 09:11 PM

With the P5B_D you need to force the 2nd PC_e16 slot into X4 speed by going into southbridge chipset configuration....[X2/X1 Mode(compatible)] [X4/ disabled Mode (Fast)]

So just make sure it's set to disabled and not Compatable then retest.

How much performance is actually lost from the 4x slot

The hit from the x4 slot is about 1% on average at this time in CrossFire or SLI (will grow as the GPU bandwidth requirements increase). The more significant hit is the limited bandwidth and speed of the Direct Media Interface between the P965 MCH and ICH8R. The time required to simultaneously move the data between the two chipsets imposes a significant overhead and bandwidth issue in graphic intensive applications. Of course, the hacked drivers also create additional slowdowns. ;)

1% ?? look at 3dmark 06 score, single 7187 vs SLI 8530, with that setup, conroe 4GHz, and GeForce 790GTX SLI can easily go over 10,000 on 3dmark06 with proper board, setup, if he switch the mobo to like P5NSLI and just do minor OC (320fsb x 11 ) i bet he can still reach 10,000

revenant

09-28-2006, 10:19 AM

^^ that performance hinderance could very well be due to poorly implemented driver hack for SLI... I guess.. or just general need for better drivers to optimize SLI for that hardware platform.. I agree though, should be getting over 10K easy with that setup..

OV3RCLOCK3R

09-28-2006, 10:57 AM

I think the scores are limited due to the 4X slot and it's also running through southbridge compared to the 16x running straight from northbridge which hurts the performance even more.

I guarantee that if the 4x slot was running from northbridge aswell, the performance would have been a lot better

andyt

09-28-2006, 12:58 PM

Well I am new to this forum and found out about 85.96_mod.
I had an extra 7900GT so decided to run SLI on my p5b dlx (non-wifi).
Here is my machine spec.
http://valid.x86-secret.com/show_oc?id=121907

I OCed my 7900GT to 550/1600 from coolbits. and here is result.
It is very dissapointing that I only get 1800 more than I run with one 7900GT.(SLI bridge is intact)
I noticed that the master card is 10-15+ hotter than the slave card. Is this normal for SLi?
http://service.futuremark.com/compare?3dm06=517497

Here is my single card bench

3DMark Score 5688 3DMarks
SM 2.0 Score 2217 Marks
SM 3.0 Score 2180 Marks
CPU Score 2837 Marks

Well obviously 4x is bottlenecking my results. Also I noticed that when I run Age of Empires 3, I only get 32FPS compared to 60FPS with one 7900GT. Furthermore, BF2 is experiencing lower FPS than sigle card. What is going on here? I get plus points running 3dmark06 with SLI setup, but games get lower FPS when I run in SLI mode.

TheForce81

09-28-2006, 10:32 PM

If you read this article (http://www.anandtech.com/video/showdoc.aspx?i=2837) you'll find out it is probably more a driver problem then hardware!
O.K. the score could be even closer to twice the single score, but this one reaches it quite well!! If Xfire could do this kind of scores, SLI should be able to match these scores at least!

TheGoat Eater

10-03-2006, 02:35 PM

SO has anybody figured out the bug in the system yet for 965 and SLI? was seriously thing of 2 7900GTOs in SLI instead of a X1950XTX if the bugs are worked out.

JoeBar

10-04-2006, 03:11 PM

I don't know if the situation has changed with the latest bios that "enhances CF performance" but if u want a safer bet go with 975X or with a X1950XTX. My :2cents:

TheGoat Eater

10-05-2006, 06:47 AM

Please set 1600x1200, 4x/16x and full quality/full textures and run the CSS stress test :)

I know AFI(P5b 7900GTO SLI) has major issues with the stress test :(

set max 1600x1050, 4x/16x and full quality/full textures and ran the CSS stress test, no issues to report.

score 65.89fps

I beat coolaler in '06 w/ this board - but he could still kick my butt!- after I get some sleep I'll do better BTW these are w/ the 84.56s!

WOW, you really got that 3dmark05 score much higher.
That's a healthy improvement, wonder what will happen with SLi bridge?
No SLI Bridge yet but still getting good scores but BF2 performance still seems like it did with the single video card -currently trying to get over 9000 in '06

Got 9014 in '06@ 3.5, yeah- is this good compared to real SLI? I'm waiting for the revised nvidia boards! How about Crossfire scores on this board - got links?

So let me get this straight, the P5b with 965 chipset doesn't have 2x16x pci-e.. but the 975x DH does?

I'm pretty sure it is one 16x or 2 8x slots

Getting a SLI Bridge - flex or PCB - which is better?

Definately flex.

Try to get one from an Asus board. Or call a shop, they might have some lying around...

Found one on eBay from a good seller - but I get 12028 3d'05 marks w/ one eVGA 7900GT at 710/1820 so I think I am going to take back the BFG 7900GT and wait for the 8800s:toast:

and 6902 in '06 with the single eVGA 7900GT - gonna take that BFG back for sure!

If anybodies interested I can post some benchmark results with the P5B Deluxe vs the P5NSLI at the same clocks next week with my lowly 6800GS's ;)

Anybody else come to the conclusion that the low benchmarks in SLI on this board is because of very poor performance in the CPU tests? Particularly '03 and '05

JoeBar

No it's because the two pci-e slots aren't 16x (the second is 4x) and most importantly, the latter is controlled by the sb.

Dr_BenD_over

11-01-2006, 07:18 AM

Well this is what lead me to my conclusion

http://24.138.52.57/05compsli.jpg

Top score is my P5NSLI, bottom is the P5B deluxe, exact same clocks. You will note the biggest differences are in the CPU scores. I've noticed stuttering during the CPU tests in both 05 and 03.

The CPU scores return to normal when not running SLI on the P5B

Both P5B, one SLI, one not. Note the CPU scores

can we get some SLI bridge/ no bridge scores on the P5B Deluxe???:confused: ?

I can run some, but I don't think there will be a huge difference with only 6800GS's.

The SLi Vs non-SLI scores are pretty convincing in terms of final value. What drivers were you using? You seem to be getting a much bigger benefit from SLI than Coolaler did

Thanks for the tests :)

What FSB were you running? after 400FSB, the chipset strap changes, that might be part of it

Dr_BenD_over

11-07-2006, 02:38 PM

84.56_Mod2, they seemed to be a bit more stable than the 85.96's

Those are totally stock. I can't say I've been impressed by my runs at 2804 (401x7). Almost thought about putting the P5NSLI back in...

K404

11-07-2006, 02:42 PM

Thanks ;) 401 will kill memory bandwidth.. if you feel like it, please could you try both boards below 400FSB? :) 380 or something :)

As for the tests on the P5B SLI Vs non-SLI, I can only guess at whats happening. SB load is being passed to CPU? CPU needs extra cycles when SLI is enabled, at least it did in the good ol days

-> just tried to use my PCI-E 4x for some bench runs... damn SATA ports get in the way, so nowt happening here tonight except for thinking :(

Haven't had a chance to do any unbridged tests yet. Whatever the glich is it doesn't appear to affect '06 very much with 6800GS's. My 5717 (http://service.futuremark.com/compare?3dm06=616598) run last night pretty much shows that.

I had 2x7600GT and got around ~5100 '06 marks on P5B Deluxe. then I've added the SLI bridge, and got ~6500. might be a reason to see slow SLI results because no bridge used ?

6800GS SLI rips 7900GTX SLI on this board (comparing Dr Bens results to Coolalers)

possibilities (the way I see it)

*driver differences

*the lower spec of the 6800 is not eating up so much bandwidth, especially on the 4X slot so there is no bottlenecking, although there is a CPU hit

Any input? I`d love to see Coolalers opinion on this :)

@Dr Ben...sorry to ask more of you, but if you get a chance please can you try the other 3DMarks? :)

Dr_BenD_over

11-09-2006, 02:56 PM

*the lower spec of the 6800 is not eating up so much bandwidth, especially on the 4X slot so there is no bottlenecking...

That was my hope when I got the board. I'd kick myself for doing so, if only the 680i boards weren't so expensive :nono:

Anyway, I'll try some other benches this weekend (I hope).

'03 24543 (http://service.futuremark.com/compare?2k3=5049182) only 315pt's higher than a run at 2275 with my old P5NSLI
'01 40123 (http://service.futuremark.com/compare?2k1=9087995)

Hopefully get to the non bridged tests today
