Right, ive recently bought a x1950 PRO 512mb to replace my 6800 GT 256mb
I immediately started having FPS plummet to around 12-15 from 70 fps in games like wow, far cry, X3 (WOW was most suprising) basically whenever my card is being used it seems to struggle intermittently.

At first i thought it was the driver conflicts between nvidia and atis drivers, so i used driver cleaner platinum and the cab cleaner and followed the instructions to a T and got rid of unwanted drivers and did a fresh install of the ATI ones.

Still got FPS drops.

Then i thought it was the PSU not supplying enough power like i see alot of problems relating to crap quality PSUs, so i got a decent quality 480W with plenty of amp on the 12V rails for about £60.

STILL FPS drops.

Oh it goes without saying i checked to make sure my card wasnt overheating when being used and also at idle. So now as a last resort im going to format and reinstall windows and pray it sorts it out.

Here are my system specs

Gigabyte 8IG1000MK mobo
P4 Prescott 3.0ghz
2gb Corsair DDR400 PC3200
Western digital HDD
Sapphire radeon x1950 PRO 512mb AGP

Is it possible that the CPU is bottlenecking my g card i know its 3.0ghz but its not quite a core 2 duo and i heard prescotts were quite bad performance wise, because my card has ample memory but the slowdowns are just so annoying happening at vital moments in a game, slideshows with no warning basically.

Any advice or knowledge on this would be appreciated.

Thanks

irrespective of being bottlenecked that card should not fall in FPS to those levels. okay, so you may not get 70 fps in a game and just 60 because of your processor, but it wont fall to 16..

there is definitely something wrong.

do a format and let us know. then we can see what we can do from there.

Ok i will so if you were in this situation would you reinstall windows as a last resort?

Reply to Ciraxis

pretty much..

also before that, you may wanna try defragmenting you drive.

Reply to blade85

Ok well ive already defragged recently, so looks like format time, ill get back to you in about an hour or so:)

Reply to Ciraxis

Yeah definitely not a bottleneck, reinstall Windows and try again.

Download atitool, some x1950 cards have this retarded issue where it lowers the clocks to it's 2d ones in 3d gaming, but atitool is supposed to fix that

You already have enough ram, so try atitool first and then you can look at upgrading and what not

Reply to I_Love_Tacos

says that atitool isnt compatible with the x1950 PRO only hehe just my luck.

found something odd in the bios that my cpus multiplier was set to 100x15 instead of 200x15 (OMG?), if thats been the problem all along then someone needs to hit me with the wackaday hammer :roll:

installing far cry now and ill report back see if any fps drop happens this time.

Reply to Ciraxis

Something else to try would be to uninstall the ATI drivers, then install some modded drivers, like Omega's. The Omega drivers come with ATI Tray Tools, my personal favorite ATI overclocking program. It's a little more complicated than ATITool, or maybe I'm just stupid. Seems to have more features, and it's very light on system resources.

Are you using XP or Vista?

Reply to yourmothersanastronaut

Thanks for the info :)

been on far cry for almost an hour and its on full blast no fps drop at all, now this could be sorted now, but what happened before i was playing all day then the next day was full of problems, really does seem like ive hit the jackpot now though.

Ill grab that modded driver u talking about if anything crops up again, but im confused that my CPU clock is supposed to be 200 x 15 = 3.0ghz but was on 100 x 15 thought that was strange because i have no reason to underclock my cpu, but im not sure how long its been at that setting so i have little to compare it to.

cheers all ill post if anything else happens

Reply to Ciraxis

lol....atleast its working now :lol: :lol:

enjoy the card 8)

Reply to blade85

i don't think speedstep was introduced back then. it may be an idea to look at this power options but AFAIK, speedstep first got introduced back in the pentium m's did it not when people actually cared about battery power.

desktop users have only recently started bleating about power consumption quite recently. i may be wrong though.

if you can't guess i really hate how people go on about heat and power being a concern. people were right to go on about it where p4's were and are concerned because for all the heat and power they generated they didn't put out great performance but IMO as long as it performs who cares about heat and power draw. annoys me that companies may limit performance to stay within certain heat and noise parameters to satisfy certain aspects of the market.

sorry to derail thread.

Reply to strangestranger

Regardless of whether or not SpeedStep was enabled, you should still get the full processor speed when playing a game like FarCry.

Reply to SEALBoy

Ok i think im going insane now i still get FPS drops to as bad as 11FPS from about 40 or so in outside areas, thought it had gone but after an hour or so of playing it came back.

I have run out of ideas now because i bought a new PSU, reinstalled windows, tried new drivers and got rid of unwanted ones, tried those omega drivers with ati tray tools.... anything else i should look for?

Reply to Ciraxis

Most likely your cpu is doing more than I thought, I thought atitool should have worked since it usually does. I really don't know what else you could try at this point, except perhaps maybe greatape could know the problem

Reply to I_Love_Tacos

is it possible my graphics card is faulty, or do these fps drops mean that theres something else im missing maybe?

Reply to Ciraxis

What's the PSU? Is it possible that your replacement unit still can't provide the amps the card needs? The X19xx series cards are pretty thirsty.

Reply to yourmothersanastronaut

It is possible, I was planning to get an x1950xt for pci_e, and I read a bit about this problem, didn't think it was anything big, until you showed me how bad it was

Try newegg reviews and see how others fixed the problem, or google it, frankly that's all I can think of at this point

Reply to I_Love_Tacos

its a tanga 480W with 28-30 amp on 12v rail

Reply to Ciraxis

thanks for the help, ill keep searching, and post if i find a solution

Reply to Ciraxis

That's probably it, I would use at least a 550w psu for that card, and would want roughly 32a on it, but that's just me

Reply to I_Love_Tacos

hahahahhahaha, that is all that post deserves taco.

the 1950pro is not that power hungry compared to say one of my 1900's.

look at my sig and look at my PSU then look at your post.

people get too worked up over power supplies at times. need to take a step back and think for a moment.

Reply to strangestranger

My bad, I thought we were talking about the xt the whole time ***smacks himself with a taco***

Still, 450w seems kinda low, I would still prefer a more powerful psu; I myself have a 550w one (they aren't that expensive guys) and I don't have a power hungry gfx card

Reply to I_Love_Tacos

ye, but even the xt you could get away with a 450 no bother. then again, i have not heard of tanga, tagan yes, tanga no.

still, i do not think the PSU is responsible.

i do not know the cause however.

to the OP have you tired lowering all the gfx details and res down to 800 x 600 to eliminate the posibility of a bottleneck in the CPU?

considering wow is involved i doubt this.

best also try memtest to eliminate the ram, perhaps only use one stick at a time.

p.s, no offence meant there tacos, it is just i see it all the time where people think throwing insanely high watt PSU's at something will immediately fix things. it is a growing trend nowadays for the PSU to be used as a scapegoat, never used to happen even a few months ago, now it seems PSU's can cure cancer.

Reply to strangestranger

Sorry i meant tangan not tanga :) and yeah ive reduced the graphics settings to low and it still happens, ill run a check on the RAM, but i doubt thats the problem because ive had those sticks a while without any problems.

Reply to Ciraxis

ye, but i have had mine for over a year and i started getting hangup and restarts.

turns out it was my ram. i am running them on reduced timings and voltages at the moment. keep meaning to buy some more.

Reply to strangestranger

Ah right in that case ill run a test tonight on my RAM, bearing in mind though ive had a defect stick of RAM before and the problems were quite varied not just to do with FPS in games, but thats only one experience of bad RAM so probably worth checking to make sure.

Reply to Ciraxis

eh check the psu im using :roll: :roll:

i dont get any hang ups or sudden loss in fps in any game.

Reply to blade85

Weird, psu is out then

In that case, I would say it's probably your cpu or card

Reply to I_Love_Tacos

I was thinking you know there memtest to test RAM is there a tester to see if the VRAM on the g card is faulty? or would i just see arty-fat-cats onscreen anyway if that was the case?

Reply to Ciraxis

Probably just artifacts, but I don't know, I've never came across a gfx card with faulty ram before

Reply to I_Love_Tacos

I'm 99% sure the problem is with the Prescott CPU.
I had exactly the same problem weeks ago.
Try search "Thermal Throttling" in google and you'll find detailed explanation.
In short, Prescott CPU's will automatically lower their frequencies if the internal temperature is above a certain level. (It's about 72 degrees Celcius for my Pentium 4 520.)
When you first started your computer, your CPU was running at full speed. After a while, your CPU will heat up and start to do thermal throttling. That caused your FPS to drop significantly.
And this thermal throttling feature is embedded in the CPU architecture. You can't disable it in BIOS. (Probably you don't want to disable it, because your P4 will be burned were it not for this thermal throttling feature.)
If you say there is a "bottleneck", then it is your cooling system.

Reply to mondaly

ah thanks for shedding some new light on this, ill have to log cpu temp see if it actually gets that hot, because like i said before never really had overheating problems ive always kept my system clean of dust etc

Reply to Ciraxis

quick question; would this new gfx card suddenly put extra load on the cpu that i never had before? because with my 6800 GT i never really experienced any fps drops when game settings were within acceptable limits for the card. Although what prompted me to get a new card in the first place was the screen suddenly going into artifacting, which is unsettling because problems happened before i replaced my Gcard.

Reply to Ciraxis

Nah, it wouldn't put any more load on the CPU, that's just crazy talk.

When you get those stutters, check your hard drive activity. If it's going nuts during the slow FPS times, then the problem could be something like bad hard drive sectors.

Run chkdisk or something if that's the case, might not be a bad idea to do it anyway.

Reply to yourmothersanastronaut

I doubt it's your gfx card, unless if it's putting out more heat (which I doubt, hardly anything besides an oc'd r600 could do that) and that could cause your cpu to run hotter. The throttle theory works perfectly with it being cpu, as it explains why it would dip and go back up. Try a better thermal paste, arctic ceramique seems to do huge wonders with p4s

Reply to I_Love_Tacos

OK looks like its the thermal throttling :) my cpu temp easily shoots up to 70+ when playing games, gonan find some prog which ups my fan speed and then buy some of that thermal paste:) didnt know about that shit throttling, 70 degrees seems v low to start slowing down

Reply to Ciraxis

Just get a cheap arctic cooling freezer 7 pro, or if you have the money a massive thermalright ultra 120 extreme/ifx-14, either of those three will fix the fps issue for you, though I would recommend the thermalright route if you have the $$$

Reply to I_Love_Tacos

hey nice one for the fast reply, and cheers for the help and info i learnt alot in this past few days, this forum is awesome!

Reply to Ciraxis

This is a pretty nice one, I personally prefer xs because the flamers and idiots that won't listen at all are instantly banned so only people willing to learn or share knowledge are there making it a lot cleaner, but thg is a pretty nice one too

Reply to I_Love_Tacos

hmm i got another q :) is it possible for me to overclock my fan? i downloaded Speedfan but i want my fan to go over 2500 rpm, is this possible?

Reply to Ciraxis

Actually, it is, but I have no idea how to do so, I've only heard of it once when someone started joking about it then someone else actually showed it could be done. Best way would probably to take out an old hdd turbine and replace your fan's engine with it and see where that gets you. But if you want airflow, delta fans win no contest there, the only company to bring you 200+cfm on a 120mm fan, but the noise level is unbearable imo

Reply to I_Love_Tacos

right looks like my fan is always going at max speed anyway, because alot of fans ive looked at go 2500 max rpm anyway so its working hard constantly, this P4 must be one inefficient beast, the paste atm is the one that came with the heatsink which im guessing is nowhere near as good as the artic stuff?

i saw mentioned that if the fan is plugged into the psu (which mine is) you can up the voltage on it and itll speed up, will this overclock it in effect or am i impatiently clutching at straws?

Reply to Ciraxis

I think ill just wait to buy some arctic cooling paste, im sure its alot better than the stuff that came with the heatsink and i read that bad quality stuff degrades over time whereas the AC hardens and lasts up to 8 years, ive had some bad paste sitting there for good part of 4 years now so looks like the time has come :)

Reply to Ciraxis

Don't up the voltage too high on the fan, that'll kill it. The p4 is flat out a horribly innefficient power sucking slob, that's why amd was completely favored by enthusiasts when the k8 came out

I would get a better hsf instead of just thermal paste, because thermal paste at most will lower your temps by 10c, but for me it's been 1 or 3c at the most, but a new hsf did wonders

Reply to I_Love_Tacos

right ok got it, may aswell go all out just to hammer down that temp, cheers

Reply to Ciraxis

Holy crap, those Delta fans push 225cfm... but at 65dB, a tornado is less loud. I think I'll stick with the AeroCool 89cfm fan I was getting for my Ultra 120 Extreme... it's around 35dB

Reply to SEALBoy

You seriously bought a delta??????? You should be sure to volt mod that thing, it'll break your ears, I only said it as a joke. Oh well, enjoy your 50c temp drop :tongue:

But you have to be careful with powerful fans like those to get all the pressure out, so be sure to have plenty of exhausts


sealboy: Yar, gotta agree that a low dba fan would be better for the extreme, though have you considered waiting for the ifx-14?

Before you go out and spend a bunch of money on a new heatsink and fan, have you tried cleaning the existing heatsink out with compressed air? I had a P4 3.2 (Northwood, not quite as inefficient as the Presc-hot) and the temps would rise about 10 degrees when the heatsink would get full of dust.

Also, I wouldn't spend a lot of money (>$50US, ~25 pounds) on a nice heatsink for that system, unless you are buying a heatsink to use on a future system. I say that because it doesn't make sense if you're getting too close to the price to just switch to a new cooler running, more powerful mobo/processor combo then (about $175US for an E4300 and ASRock Dual-VSTA, which supports your existing DDR-400 RAM, and has AGP as well as PCIe graphics).
