Nice tests, thanks.

Could you possibly show the details of the 3DMark2001 runs? Strange how that suffers so much while the others are dead even against i975.

hmm 965 isn't doing well at all heh.

Some Crossfire pictures.

mee want RD600!

nice tests.. :) I think the 956 chips have done great running 16x and 4x on crossfire setup.. :) hehehe..

:woot:

nice tests andre many thanks!

Interesting results, thanks for taking the time to post :toast: .

Regards

Andy

nice results there, so the 965P is good enough for crossfire :toast:

i never thought 965 would be so close to the others. thanx for the tests andre. i wonder how a 16x 16 board would fare with this same set-up?

thanks for the test andre!

I don't understand the 01 performance of the rd600...why in this test is so close to the 965 while in the other tests is better then the 975?

Marco

Maybe u can throw in this test a i680 board as well.. :D

thanks for sharing

Good amount of info, thanks for sharing!:)

Hi Andre great work!
Why not test the Asus Commando with one frequency adapted to its characteristics. All we know that chipset 965 do not go well in the range from 400-500 Mhz. You could make also a one bench at 550x7=3851 in order seeing if he improves? Thanks and good job.
p.s. Excuse my bad english.

Remind me again what's so great about RD600? And don't say asynch RAM, please. :)

Wow! 975x :stick: rd600

tought that rd600 would be stronger in 3d

i975X is greate........

thx for sharing the results.

Was it chipset limitation of 16x 4x on 965 or something else is the problem why 16/4X is made?

SLI is also crap on 965 due to 16/4x :/

Andre, as others have said great comparison. Nice and clean :toast: Helps me with the decision on if Im going RD600 or not.

indeed...

thanks for the benchies Andre. :)

Thanks for sharing! :)

Nice tests! :toast:

If you could test with x1950xtx would be even better, maybe 1950pro doesnt pull enough performance to notice differences between chipsets.

Regards!

Interesting how you did the comparison.

RD600 - Slack timings, high FSB
975 - Tight timings low FSB
965 - Tight timings high FSB

The reason 965 can keep up is because of the increased FSB/timing ratio vs the 975 and the 975 wins out in 01 because of timings.. (obviously 01 is way more hardware dependant). Better timings = better 01 score any day. Ask hipro ;) . Not to mention the 4MHz increase in cpu speed.

Anyways, thanks for sharing :) . I think RD600 will be my conroe board.

I don't get what's so great about RD600 in a non-Crossfire environment. I'd go Asus Commando if I had an E43/63/6400, Crossfire and didn't care about getting a few more points in 3dmark in CF. Or for subzero, 965 wins. 975X is still the overall winner, I think, what with higher and higher FSBs being possible with 975X.

Its not only the crossfire performance. The sheer amount of options available in the board make it attractive.

We are at XS, and we love to tweak. Thats what overclocking is all about.

Nice review.

I would like to see a comparison of RD600 running at tight timings and 1T command rate versus an i975X board running tight timings and 2T (its max). Bandwidth limited tests like 01 or 05 would be great. Keep the FSB the subtimings the same. Thanks.

The memory timings don't effect 3D Mark too much,so I just use the same FSB.

We know 975X is hard to use high memory fsb and memory timings don't effect 3D mark too much.
RD600 DDR2 1200 CL4 2T is very tight timings. I think this comparison is fair.

AS to 4Mhz, RD600 and 975 use FSB 428 on BIOS. I don't reduce RD600 CPU FSB on BIOS.

Thanks for sharing your findings.. :)

AndreYang you :rocker:

a little OT.. :)

DFI RD600 is available now..

It's out of stock now but Newegg should have it by tomorrow morning. Damn, those sold out fast at ZZF.

Check out the Asus Commando thread in the Intel section. Unless Asus came out with new and hugely improved bios, you can't normally overclock on Commando at all ;)

that's very true, even on the 975 chipset pushing ddr1104 at cas 4, does not weald any extra results in 3d marks over lower latency tight timings. Most difference I get is maybe 100-200 points max on 3d mark 01. Conroe is just not that memory speed hungary it seems. Only thing is that you get more enjoyment of tweaking on the ICFX even if some areas defy logic..

Would like to see 600mhz 4-4-4 compared to 428 3-3-3 on same board. I bet the first one is faster in 2001, memspeed does make a difference.

depends what you can run 24/7 voltage wise how much time it takes to get 600mhz stable, and the actual points difference.

100-200 points is too anal for me, unless I was aiming to crack records (assuming I was able to get close in the first place), if we were talking a 1000 or so points then I'm with you...

regards
Raja

For me 8x558 beats 9x500 by ~650 although cpu is 35mhz slower on multi 8. The difference certainly was bigger then i expected. Same settings only memspeed is different.

9x500
8x558

Tight timings vs mem mhz next :D

manipulating the dividers on the same multiplier should be interesting too..

though in theory strap between 500-558 should be the same...

Andre, can you limit PCI-E lanes available to the video card on the boards?

Might be interesting to see 1x vs. 2x vs 4x vs 8x vs 16x or something similar. Single pref but x-fire nice as well... :D

hey Andre, have you tried a Kentsfield with the RD600 ?

kentsfield is hard to high fsb on RD600.

Can u run some spi's also [1&32m] :)

Thnx . Tom

Can you run the 965 board with the 1333FSB strap (boot at 400mhz or lower and clockgen up)? I think the difference bewteen the 975 and 965 would be much smaller then. The 4X PCIe setting shouldn't matter as much as it seems from the tests.

Damn, bad news :(

Can you elaborate, what's "high fsb" here? Has RD600 the same troubles with Kentsfield as nVidia 680i boards do?

Edit: nevermind, some discussion with precise numbers is already going on here: http://www.xtremesystems.org/forums/...125862&page=45

Great stuff, but hoe did you get the X1950 Pro's to work in Crossfire on the 965 when they the 965 chipset does'nt support them in crossfire:confused: Atleast not on the P5B Deluxe (Even with software crossfire).

I read it was because the 965 chipset does'nt have support or internal writes and later I got that confirmed by Asus.

I was just wondering, I own 2 X1950 Pro and can't use them in crossfire with my P5B DLX :slapass:

I don't know why your P5B-Deluxe didn't support Crossfire. I'm sure my P5B-D is no problem with crossfire X1950 Pro.

RD600 Super PI is very slow. It's slower than 965 975chip 30sec~1min 32M.

Indeed, I was kinda suprised by the results on the Commando with the CF x1950's. Wondering if I should give it a whirl on my P5B....

really :confused: :eek:

Can you try SPI 1MB at the same CPU and RAM speed?

965chip-------9447???

I have p5b dlx and 2 x1950pros in crossfire and get nowhere near this score.
My cards are running 651/776 my highest recorded score is 8850
http://service.futuremark.com/compare?3dm06=1042970

would a 200mhz increase on cpu and 4mb l2 cache and 15mhz higher mem speed and extra 512MB video memory make almost a 600 point difference??? I guess so.

my cpu was 7*515 / 1:1 @4-4-4-4

I was considering buying rd600 board for better crossfire performance but now I'm not really sure after reevaluating this thread.

i dont understand why RD600 is so slow

It's still very new to the market. I'm sure there are plenty of optimizations still to come.

async mem means a seperate bus so it's slower but more easily used.

I think different results the system as a whole, instead of work of system with two videocards gives. For a single videocard results should be similar

could someone test max 1M cpu frequency on RD600 vs other decent boards?
maybe the vtt adjustment and such will help to achieve higher final 1M speed on RD600?
just a thought
