Artifacts???

[I.R]

I've been mucking around with 2001 and I get artifacts when I push the memory of my card above 559Mhz...... it's rated at 3.5ns which according to my calculations = about 571Mhz...... I was wondering if the artifacts were caused by heat (the ram has no cooling on it) or by lack of power (poor 250watt PSU I swear I'm gonna replace it soon) or just by crap memory :(

Anyway my card is a Gainward 64M 4200 and here is my score (http://service.madonion.com/compare?2k1=3751453)

Artifacts are the memory DYING
Clock that sucker back down till u get no artifacts.
Get some tweakmonster copper ramsinks.
Or some of those ramsinks that JB has for $1 each
Who makes the ram on your card?
Normally gainward cards run somewhat above their memory's rated specification.

[I.R]

The ram is made by Etron tech!??!?!??! The default ram speed is 513Mhz..... this is a non-GS. I was thinking about getting one of those Tt GF4 coolers but no one stocks them :(

[SilverPriest]

Etrontech you say.....
3DFX used to use their memory on some of the voodoo3's think.
I've seen some gfx card with that on recently.
Memory is a bit foggy.
Since it's a non GS card, you cant expect them to use wicked memory ;)
Although mem not even making it to its rated speed sucks, but its a fact of life.
Grab some ramsinks, get artifact tester (where from i've got no idea, do a google) and see how she goes....
Default ram speed is 513mhz?
I was under the impression that gf4 ti-4200 64meg cards came @ 500mhz.
You using gainwards drivers or reference ones?

Artifact Tester here: http://www.majorgeeks.com/getfile.php?file=201&site=2

If you have an old Heatsink lying around you could [H]a><0r it into ramsinks and stick em on with a bit of teh thermal epoxy...

[I.R]

I'm currently using 29.42 but even the default drivers 28.32 (I think ) it was at 513... I think it might have more to do with EXPERTool but don't really know..... I thought that the dispaly properties would give default speeds before any third party software overclocking :confused: and that's at 513 as well :confused::confused:

[Humantuckshop]

Try using Rivatuner to overclock, it kicks ass. http://www.guru3d.com/files/rivatuner/

[Agent666]

the 64mb gainwood ti4200 I have is clocked at a default of 513 as well

SP and IR the clock speeds are coded into the bios of the card so it is independant of the drivers used...... :) ie it takes user intervention to OC your card .... grab a bios editor and see for your self http://x-bios.3dgames.ru/

I 2 get artifacts but running at 540 and 270 mem it runs sweet .... BTW when you can physically see the artifacts you are probably already 10-15 Mhz over what the card can do.... get yourself and artifact testing program and you will see what I mean......

iv got a Gainward GF4MX440 Non GS (4ns)

and it Overclocks quite fairly at stock cooling.

Core:270@300
Mem:400@480

at tht speeds i only get 2 ARTIFACTMARKS frm Artifact Tester and Hardcore Mode (or whtever they call it).

[KingJackal]

Your memory probably CAN do the speed it's rated at - just not on that PCB and under those conditions.

Remember that on an overclocked card running off an overclocked AGP bus, signal purety will be affected. There are too many variables to reasonably conclude any discussion on why your memory can't run that fast - but suffice to say if you can actually SEE the artifacts, then you're about to make yourself another expensive keychain :(.

One artifacted pixel out of 1million pixels is too much - and your pitiful eyes ( hehe :p ) can't see that. So if you can actually SEE aftifacts, you're waaaay over where you should be.

It is a dissapointing overclock, but I guess that's what you get with a budget card. And yes, Gainward's non-GS cards are budget....

:p

My leadtek o/c's too 324/534 with NO artifacts :D

if the mem aint hitting it's limit then the problem probably lies in the voltage. ever since ATI did their "voltage cripple" trick on the 8500LE, many manufacturers have cottoned on. in your case - gainward - i wouldn't be suprised if this is something they do to distinctily set their "regular" cards apart from their "golden sample" cards...

[SilverPriest]

That actually reminds me of a thread i read on a forum once.
This guy was messing with his gf2 ultra, knocked off a cap, and not only did it still work, im sure it oced higher :S

If you had a look at the compare you'd see that the bench was run on a default AGP bus ;) :p

But yeah the rest of the stuff there makes sense :D

Just wonderin what u ppl think of this oc. I've found the limit of this card, it's 520 I believe, didn't move the vcore higher than 250 during that limit test. Would I be right in sayin that I probably have artifacts in lower res such as 800x600 with this oc?

Leadtek Winfast GF2 Ti 64MB 4ns DDR:
225/400 @ 250/505

[Agent666]

mind explaining why you think that????

[Antallica]

Well I go about mem 510 and at my current res (1152x864 @ 75hz) there's no af's, under load produces none either (using af checker). I do some 3dbenching (1024x768 @ 60hz) and I hit some af's right away during the bench.

nice, i was able to reach 331/484 without artifact when i installed a 120mm fan blowing directly in-front of the card.

[crux]

I don't think that artifact tester is so good.
It reports no artifacts under the hardcore test under dx7 and in software yet in 3dmark2001 it is clear there are.

[Antallica]

I hear ya, however I think all that tester does is put the cpu under load (the settings being just longer times under load) and check for artifacts under the current res you have it at (which in my experience produces artifacts in bad oc's for the vid card when under load)

Anyone with me here?

[I.R]

I don't know anything about that artifact tester cept that it doesn't like it when your monitor goes to stand by mode :eek: 75672...... woo hoo I got the high score :p:p:p:p

Great score man, kinda like my SiS 2MB onboard powered by a V12 engine :D That's why I have features like that off, good old power button does wonders you know hehe.
