I don't have my 6800 GT yet so i can't test it out by myself.
I read on a german hardware forum that FW have an incredible impact on the 6800's performance. I was tellign someone to disable FW to get stability andd this person showed me why this is no good idea.

His results: (6800 ULTRA watercooled i guess)
Aquamark 3 470/1300: 72800 without FW
Aquamark 3 430/1200 75000 with FW

Can someone here confirm this? I am looking for performance not for the biggest mhz score! If this is true disabling FW would be more than redicilous!
How's the impact of FW in games and 3dmark05?

Disabling fw will make your cpu perform much worse. Therefore you wont notice much of a difference with very gpu intensive apps (3dmark03), but with bery cpu intensive apps (3dmark01, f1 challenge etc) youll notice a big difference.

Stability might be an impact, though.
Never had a prob w/Geforce DDR ->
but i have had prob's with Radeon 9000 ->

My former BFG 6800U OC wouldn't overclock with FW on. When disabled, I was able to push the videocard extra 28MHz on the core.....only to lose 200 points in 3DMark03 ... :lame:

just keep FastWrite on....

its good to make things write fast :D

Man, the last time I wrote fast was when I tried to finish a novel in 30 days.

If there's no stability problems, just keep the FW on, I guess...

Yea I noticed this too. Keep it on!

Hmm it seems like this guy was right. More and ore people report that they actually get lower benchmarks with higher mhz clocks when they disable FW.
I can't wait to test this out by myself.

Synthetic benchmarks do not always represent real world game performance. It is my experience that most games run faster with FW off and higher clockspeeds compared to FW on, especially if you use high resolution and AA/AF.

Who wants to play games when we have synthetic benchmarks? :box:

It's a stability thang. If your machine can run with FW enabled, go for it. A lot of people don't have that option.

I get lower results with it off in 3dmark03 also. My CPU score drops from 1,050 to 700...

I tested the 6800GT fast write performance on aquamark, 3dm03, far cry, and doom3, see here - http://www.nvnews.net/vbulletin/showthread.php?t=36203

Aquamark shows much more benefit from fast writes being on than any of the other games/3dm03, so in your actual games 470 core without fast writes is faster than 430 core with fast writes.

Thanks a lot for linking to that thread. That info helps out a lot.

Must say that FW increased FPS alot on my system. My 2k4 fps went up by at least 5-10 fps. I'll be happy if system stays stable with them on.

I htink mine have been off ever sense I got my card back in september ... maybe I should try using them... although I have no gaming issues.

I get better fps and benchmark results with fastwrites enabled than I do with a vid card overclock. It costs about 2.5K in Aquamark, 1K odd in 3d01 and a couple of hundred in 03/05. UT2k4 loses frames with it disabled as does farcry, hl2, cs:s and the rest of my games list currently installed.

I've always been a believer of keeping fastwrites enabled and if you're overclocking, don't believe the myth it will give you better or more stable overclocks as it only just MIGHT in extreme circumstances but with my winchester 3500+ sitting at 2.7Ghz with fastwrites enabled on my 6800GT I see no reason in the world to disable it as it does nothing but kill my performance and this has always been the case as I've benched each system extensively with different settings and result for me = fastwrites enabled or bust.

Now where am I going to find those 2K Aquamark points to get me to 80K, currently up to 78K from 76K :spank:

Well, for me fw disabled is the fastest because I can't even run my card with it on:p But yes, I do think there is a performance hit but for some there is not other way. On all GT and Ultra's I have used, fw has to be disabled when the core runs past about 405MHz:( Can anyone confirm if the via boards have this issue also?

Man you are so wrong...Disable fastwrites,,,Do a couple of bench's,,you pick them,,make notes of the results...Then go on and enable fastwrites, and run the same bench's....Most likely your scores will be higher without it,,Fastwrites are the major cause of the HL2 stuttering, and freezing. And,,,so many other problems they're to many to list...Some systems run fine with fastwrites enabled..But it certainly does nothing to slow down performance when you turn it off....Try it and see for yourself..I bet ya won't notice a damn thing......
Good Luck.....:D and trust me. It's a waste of time..

I get higher scores with fastwrites on so I leave it on because it does not cause me no problems,but it is true the card will not overclock as high with it on.I can over clock to 445/1200 withit on but I get higher marks with it on,and I can overclock to 475/1250 with it off but to me it is not worth haveing it off and it does not cause me no problems with it on.

I have fw on, no stuttering in HL2 or any other game I use. Does not affect my OCing ability, same limit with or with it off. Each their own. I do see a performance increase with them on as a side note.

eh.....I guess it's by a pc by pc basis. I've always heard FW=bad. Got home today after seeing this thread and put it to the test. Using 3dmark2k1 I gained a healthy margain with FW on.

My system is:
AMD64 3400+ (2.4 ghz)
DFI Lanparty UT 250GB DFI approved nforce drivers
1x512 Mushkin 2.5-3-3-10-1t @ 200Mhz
6800GT 400/1100 Forceware 66.93, CP set to best performance, AGP app 128MB
Audigy 2zs

With FW disabled I scored 22551 at stock cpu/mem settings. With FW enabled I scored 23095. To put this in perspective, when I ran 240*10, 3-4-4-10 I score 23005 with FW disabled.
Have a look for yourself.....

Now I have no idea how to get the best possible score out of 3dmark. I just installed windows on this new proc and mobo 2 days ago and very seldom use 3dmark other than to make sure that the driver installs went well.

I dont think Nforce 2 boards have a problem with fast writes. Mine have been enabled for sooo long.. On like 4 different GPUs..

Oh yeah, It's a pc by pc thing for sure....I never did disable it before I got HL2 but when I did disable it, the game stopped stuttering and freezing. That's the only game that caused a problem for me. I'm using an Nforce 2 mobbo,,,,an NF7Sv.2.
You know, Schumi4ever may be right to a degree. It wouldn't be much worse with it disabled, but maybe just a little bit worse..but whats everybodys definition of much, versus a little bit..LoL I left it disabled for now because I don't really see or feel any difference. I'm gonna go check it right now again and see how I feel today.. he he.

I think this is a question of balance, this is all. If with FW=OFF you can overclock more and you are scoring in benchmarks more than minor overclock with FW=ON go ahead with FW OFF.

I mean, take a look at these benchmarks results:

3DMark 2003 results
--------------------
Overclocking type:Reference nVidia 6800 Ultra
Core/Ram: 400/1100
FW:ON
Score: 12417

Overclocking type:Stock BFG 6800 Ultra OC
Core/Ram: 425/1100
FW:OFF
Score: 12710

Overclocking type:Max without issues
Core/Ram: 440/1140
FW:OFF
Score: 13121

Like you can see i can not pass from reference stock values if i have FW=ON, if i set FW to OFF i can overclock up to 435 core / 1140 ram without any issue. This is huge improvement for me.

You are pointing the fact of better scores in 3D Mark 2001 with FW ON, but what actual game is based on same technology than 3D Mark 2001?
I think it is more realistic take into account more recent benchmarks. I get improvements disabling FW and be able to overclock, in 3D Mark 2003/2005 and Doom 3 too, i have not tested Aquamark, sorry.
