XFX 8600GT SLI beats 8800GTS 320MB OC and Costs Less

[Harvik780]

Guys can you believe this

Compare the above two

[Who]

well 8600 GT scores pretty high in 3d mark, can you post FPS result in games like oblivion, company of heroes etc on 1024 x 768 with AA (&without)(i am planning to use SLI too for minimal gaming), also i think SLI requires a more powerful PSU so it costs more in the longer run, also it reuires a SLI mobo which also cost some buck (not much though)

[Harvik780]

I am posting benchmarks in newer games like Call Of Duty 4 Demo,Crysis Demo,Unreal Tournament 3 Beta Demo,NFSPS demo and also lost planet with patch 1.4 in DirectX 10.Wait till midnight.
I don't have Oblivion and Company Of Heros.

[Who]

that's all right, if they perform good in new games they should work very nicely in the old ones anyway thank you very much for your help harvik.

[cynosure]

I think there is some error. your SLI config is showing to be better than all 8800 series cards at the one time (with 0 AF). Is this some joke or you have superclocked your cards?

[Who]

cynosure i think those results are real , 8600 GT really do get very high scores in 3Dmark also all the other cards 8800GTS 320 MB overclocked ones except for the 8800 GTX , also i think the cards are not fully overclocked with some volt- modding you can overclock an 8600 GT upto

Core :- 760 Mhz+
Shader:- 1720 Mhz +
Memory: 900 Mhz+

This clocks would even beat 8800GT in 3Dmark but it needs some pencil volt modding which can be risky but i myself am intrested in real world gaming tests.

[assasin]

interesting stuff.was satisfied with my XFX 8600GT but didnt know that 2 8600GT in SLi wud beat the 8800GTS 320MB else i wud hav got another 8600GT and setup SLi.bad for me.

[cynosure]

Gotta download 3Dmark06 and gotta overclock my 8600GT

[Harvik780]

I have tested three games now.m installing Lost planet now in x64 vista.Will post the benchmark results soon.

[Who]

harvik good news , you see crysis can't really take advantage of SLI right now also nvidia are still working on drivers optimized for crysis also crytek is working hard on optimizing the game & there is tweak guide out for crysis already which boosts some FPS of crysis so this all add up to one thing 8600 GT SLI will able to 1024 x 768 2x aa with most settings high in the near future

[hahahari]

A friend of mine reported of getting 20-30 FPS for crysis at max setting in 1280*720 for a 8600GT ultra 512 [OC card].In vista btw

[Stalker]

@ Harvik780

u probably are trying with the newer drivers.....while 8800GTS results might be with the older drivers

[Harvik780]

^^My brother gets 9630 in 3DMark06 with the 169.04 drivers.

Yeah baby, I got that card.

[Harvik780]

LOL my 8600GT OC SLI is the fastest system compared to similar systems.





I just ordered for Artic Cooling Mx-2 from theitwares.

[naveen_reloaded]

Awesome info guys.. I have 8600GT and will buy another and sli if this is true

[deathvirus_me]

Well , 3DMark score seems nice. . how many times have u played it ???

[Harvik780]

Well i have stress tested the cards a lot of times more than 5Hrs.Have tested a heck a lot of games and crysis was obviously most demanding even with the OC.Still waiting for the crysis patch.
Actually 3DMark is the best real world benchmark because it does not favor any card.Whereas crysis on the other hand favor's the 8800series.
I have ordered for a Arctic Cooling's MX-2 thermal compound and am thinking of increasing the clocks further by 40Mhz to get over 10,000.
The 8600GT is also not weak at AA and AF.I have tested the SLI setup and compared it to a single 8800GTS 640MB with 4x4AA and 8x4AF and it scored only 202 less with a score of 8294 at 1024*768.

[darklord]

@ Harvik, have you personally done these tests ?
If yes i have some questions for you,
I see all Geforce 8 series cards there, then why was Radeon X1950XTX used ? Shouldnt we have 2900/2600 and so on ? for a fair competition ?
There are 2 more 8800GTS, care to mention whether they were 640MB or 320MB ?

Cheers !
Amey

[Harvik780]

No that comparison is pretty old and found it on some reviewer's site.
I have seen the latest comparisons with the latest drivers.
My brother scores 9690 with the same settings in 3D mark with a single 8800GTS 640MB with the latest drivers.

I haven't done those tests i just posted the benchmarks here for some games.

I would also like to mention that i am having problems even though i have installed the SLI hotfix's from microsoft for vista.

[darklord]

Ok cool !
Nice score there harvik

Can we have some overclocked scores please

[Harvik780]

^^I scanned for artifacts using Artifact Tester 5 and Ati tool 0.26(Latest).There were no artifacts at all.I have overclocked the cards to 700Mhz Core/ROP domain and 1566Mhz Core/Shader Domain.The memory is overclocked to 860Mhz.
I am really interested in getting the Artic Cooling's MX-2 and see how much more i can go with that.

I also tested a lot of latest games.
Crysis
UT3
Gears Of War
Bioshock
COD4
NFSPS demo.

[darklord]

Hmm, but could you post some scores ?
Why i am asking is , i want to see how efficiently SLI scales with clocks.That would be interesting to see.
One suggestion,
While benching with overclocked cards, it will be a pain to keep both the cards cool, till the time you bench, you can keep 2 x 120mm high CFM fans over the 2 cards which will keep things cool.
This is possible only if you are benching on a benching setup and not if you have the PC assembled in a Case.
What do you use to OC the cards ?
Why not test what happens with CPU clocking too ? as in how much does SLI benifit from overclocking the CPU alone.

[Harvik780]

^^There you go


The max OC with CPU i got was 2.8Ghz(primarily because of 667Mhz RAM)max OC on GPU without Artic Cooling MX-2 was 702Mhz/864Mhz/1566Mhz.
There's probably no way i can get an HSF cooler to fit in my SLI setup nor a passive cooler is available easily(even tried from matrix 3d LTD).Water coolers are probably hard to source here in India....found that after looking for Corsair nautilus 500(i guess).

Here are the test results including Scaling in SLI at different resolutions and Clocks.

ROP-540/MEM-700/Shader-1188,Resolution -1024*768,CPU-2.8Ghz
Score( Single ) - 6114 Score( SLI ) - 9896
Scaling - 1.619x

ROP-702/MEM-864/Shader-1566,Resolution - 1024*768,CPU-2.8Ghz
Score( Single ) - 7432 Score( SLI ) - 11480
Scaling - 1.545x

ROP-540/MEM-700/Shader-1188,Resolution - 1280*1024,CPU-2.8Ghz
Score( Single ) - 4861 Score( SLI ) - 8177
Scaling - 1.682x

ROP-702/MEM-864/Shader-1566,Resolution - 1280*1024,CPU-2.8Ghz
Score( Single ) - 6018 Score( SLI ) - 9825
Scaling - 1.633

ROP-702/MEM-864/Shader-1566,Resolution - 1280*1024,CPU-2.33Ghz Stock
Score ( SLI ) - 9225

The software i used for overclocking my GPU(s) was ntune because most other softwares currently only support experimental SLI overclocking support.I have downloaded ATI tool 0.27 Beta 4 and will overclock using it and show some more results.
Since my cards are not that big i already use two 80mm fans to blow directly at the GPU heatsink to keep things cool just in case.
As u can see we have some interesting results here.At higher resolutions with higher overclocking we get higher scaling in SLI,so SLI is pretty much for high res gaming.If u have SLI setup u would wanna game at resolutions over 1280*1024.
Also we can see that overclocking the CPU gave me a score jump of precisely 600.

With this setup i can play crysis at High with no tweaks at 1024*768 with 2x AA.

[darklord]

Wow !! very detailed testing there harvik, good job !!

I am saying, keep a very high CFM 120mm fan next to the SLI bridge over the 2 cards, parellel to the board, will give you slight headroom for better clocks IMHO.
Also IF possible check if the thermal paste on the core is making good contact with the heatsink, most of the times i have found, it doesnt do it.AS5 will help you cool the card a bit.
I guess you are using the P5N-E SLI mobo for testing, its based on the 650i SLI chipset so you can run the RAM in unlinked mode which takes memory out of the OC equation and can push the CPU even more.
BTW, i hope you are cooling the PWN area with 80/120mm fan right ? If not, do that, keeping the PWM cool, helps in improving stability.

[Harvik780]

^^Thanks
I also wanted to install a 120mm fan but the problem is that its not available easily at my place.I'll be ordering for a 120mm fan from theitwares now.
Also the thermal pastes are definitely not properly applied by default.I have checked the thermal pasting on both the cards and they were a bit awwy,..very thin layer of paste on the core chip.I didn't play much though as i am waiting for my Artic Cooling's MX-2.
Well i tried the unlinked mode but i encountered problems running in unlinked mode.With Ram and processor linked orthos did not encounter errors for 5Hrs.
But as soon as I unlink the ram and processor i have problems passing the orthos test even when i set the clocks of the ram to lower values than 800Mhz and the processor is at 2.8Ghz.
I haven't played much though as i was looking for the sweet spot with both processor and ram and since this config does not have a cooler installed.
For the PWN area yes I have already installed an 80mm fan had to do a bit of modding though to install one.

[assasin]

but my 3DMark06 results speak something different:

[darklord]

^^ Arent you using an OC'ed Quad ? whereas he is using an OC'ed C2D.

[Harvik780]

Yup my processor is a bottleneck.U can make that by looking at the CPU score i have provided.
I again tried ocing my processor...set my ram to 667Mhz and processor to 3.0Ghz and the system did not boot.So its clear that EXX50 series is not a good overclocker.

[assasin]

^^^ why dont u try ocing ur ram too?maybe it cud help oc the proccy.even i've oced my ram from 667 to 800MHz and its running perfectly stable.

also why dont u try with ur E6600.it sud easily oc to 3.6GHz at 1.41 vCore.
