Youre suggesting an X800P is faster than a 6800GT?

It's quite possible that a 350/500 GT is slower than a 500/500 X800P. ATi is known to suffer less of a performance hit with AA+AF, so it's probably more likely the X800P is slightly faster with AA+AF.

That would be just AF, nvidias AA hit is very similar, and ATi doesnt have quincux which is <3

Dont forget youre comparing a 16pipe GT at 350/500 vs a 12 pipe pro at 500/500.

I'm glad humey cleared up the issue on fastwrites, because I was about to post a similar reply. Also, having FW on is what allows me to play the Step into Liquid HD trailer on my Athlon XP system without any frames skipped, so it's definitely a good thing to have when it works. Did you try playing it with the 6800gt and see if it skips any frames, with FW off?

 

[Megatomic]

No but that's a good idea munky. I'm sure it's gonna choke.

It's not like there was gonna be any difference, & also, ATi's drivers are less buggy these days.

the 6800 gt is a bit faster, so i'd say he actually upgraded. nvidia seems to have better 64bit / linux support too.

So reading over this thread (and others) it seems that the NF3 chipset doesn't impliment Fast Writes correctly. Are there other particular chipsets exhibiting this issue on a regular basis?

So far, NF3 seems like maybe it belongs on the "er.... I'll pass" list.

edit: who cares if a mobo overclocks well when it makes you turn off performance features to do so. Kind of antiproductive :thumbsdown:

FW works fine with the X800 Pro, the 9800 Pro, and the 6800 OC that I've had in this motherboard. I'm not certain that it's a design problem with the motherboard...

good to know that.. I was starting to doubt the NF3.

I had exactly the same problem dude. Get a 480 watt psu. I did and it cleared every thing up.

 

[Megatomic]

I've decided to sell this card and get myself an X800XL instead. But I'm glad to hear that I might have been right initially.

 

[Megatomic]

Ok, so I ran the SIL 1080p video using WMP10 and FW 71.84. I got zero dropped frames (which surprised me) but CPU usage was in the 90s to 100% the entire time (which didn't surprise me).

I feel kind of foolish for thinking that something was wrong. As DAPUNISHER said, I got what I paid for. Actually I got more as it does overclock some. I think with a beefier PS with a stonger rail this card would probably soar. I just don't want to buy another PS right now.

 

[Megatomic]

Oh and RTHDRIBL 1.2 ran for over 12 hours yesterday. Resolution was set to 1024x768 and ran full screen. I had NV control panel up and selected to show temps. When RTHDRIBL 1.2 closed, the temp. indicated 61C which is really low, especially since my X800 Pro would peg out over 70C. Not to mention the temp. readback bug in the 71.84 drivers which inflates temp. readbacks artificially.

 

[imported_humey]

O/c the core and memory a tad and your temps will read properly, i run 425/1100 out box and yes ive notice it is higher on some drivers, so i just run 450/1200 anyhow and its lower.

 

[Megatomic]

I don't think I have the juice for that overclock humey. Besides, I'm selling the card now and I don't want to do anything that will ruin it before I do so. At this point I'm just stretching it's legs to prove to myself that it's ok to sell it. So far I'm good to go. It's perfect at stock and up to 375/1070.

Yes, that is because in the Nvidia architecture, they take up an ALU when doing AF. Additionally notice the clockspeed difference. Nvidias fill rate is significantly lower than ATIs (350 vs 500).

Try the Tweaks R Us drivers. They have worked flawless for me since day one. However it sounds like a problem else where. Is this a PCI-E or AGP card. Additionally is your AGP/PCI bus locked at the appropriate setting? If you haven't already look at the card itself and see if you can see any defects (bent or bulging capacitors, scuffed contacts).

[imported_humey]

LOL, you dont need that much a o/c but put it up few mhz and bug will go away, im not sure if you only need do core but i guess since its core your reading only need do core.

Thanks for the tips but the card is pristine aside from having the NV Silencer 5 installed on it. And I did remove and reinstall the cooler so I had an opportunity to see it's entirety in all it's naked glory. The card is fine it's just not an astronomical overclocker while it's in my rig.

I use FW without an issue, and so do a lot of people I know with Nforce 3.

I think the problem is PSU related, you could try it with a friends PSU maybe.

 

[imported_g33k]

Interesting, I posted a few days back about OC'ing a 6800gt and no one ever told me to turn off fast write. I just turned it off and it did help my OC a little. With fast writes on, I couldnt get past 10mhz over stock on the core and it would throttle. Now I can get to 383/1.06. Not exactly a stellar overclock, but a bit better.

I think, like the OP, I just have dud overclocker. My benchmarks scores get worse with higher frequencies.

not sure where you get that.. frankly the nf3 is hands down the best chipset avail. for this platform - and FW works fine with my GT on this system..

might be something with the particular motherboard, or his particular bios revision, or some other cause as there have been many that haven't been ruled out.

The X800pro is faster in DX -- with AA/AF, the 6800GT faster in OGL.

In xbit latest roundup they tested 27 games. (31 benches as 4 games had 2 benchmarks).

At 16x12-4AA/16AF the Pro was faster overall.

6800GT ? ? 9 wins
X800pro ? ? 13 wins
TIE ???? 5 ? ? (< 5% difference)

At least 4 of the benches the GT won were OGL leaving the X800Pro winning in DX 13 to 5 over the 6800GT. So I?d say the GT is actually a slight downgrade in DX from a X800 pro.

At 12x10-4AA/16AF ?

6800GT ? ? 9 wins
X800pro ? ? 10 wins
TIE ???? 8 ? ? (< 5% difference)

10 to 5 for the Pro over the GT in DX.

 

[Megatomic]

Well, I have sold my GT and I will soon have an X800XL. Everything else in my system will be the same. When I get it I'll report back as to whether or not I can use Fast Writes and if I can overclock or not.

whoa guess im abit bat like in the vision department too, i could of sworn you side graded from a 6800Gt TO a x800Pro

my bad

in that case....not side grade, UP grade

My nforce3 250 board and 6800gt don't get along at all with fastwrites on, while my x800xt-pe does fine on the same setup regardless of fastwites. I did some googling around after I figured out the problem found it was rather common issue for the motherboard chip and GPU combo.

odd, i have a nf3 and FW is on and my 6800Gt is flawless, overclocks to about 410Mhz and 1.12Ghz

Snowman, are you able to overclock your GT while it is installed in your NF3 board?

However the Forceware 7x series has some significant performance improvements (driver-wise) over the 66 series.

i bought the card from him, hopefully i won't have any problems as i have a dfi nf3 mobo and 350w antec psu.


will update once it gets here:beer:
