Is this quick enough for a 1900XTX

Mort2k · 2 Jul 2006 at 11:33

Hello

I have just upgraded from a 7800GT to a 1900XTX

Sys Spec
Athlon 64 3500+
2 gig Corsiar XMS Pro
ATI 1900XTX 512MB

I was expecting a major *wow* from the card but so far i am unsure if i have other issues as it does not seem that much quicker!!.

Playing CS:S with the 7800 in 1024x768 i got 60-80 fps, with the 1900xtx i get the same!!
if i up the res to 1280x1024 the frames drop to 50-70

When i run up FEAR i get an autodetect setting of Medium!! and the game runs slow !!

the free download of 3dmark06 gives me score of 4500

so my question really is, am i expecting too much from the XTX or do i have an issue elsewhere ?

many thanks for all your help in advance

what 3d mark 06 score did you get on the 7800gt?

Did you fully remove the Nvidia drivers with drivercleaner pro etc...

sounds like issues elsewhere, maybe your computer is setup wrong, and you have loads of other programs running the background, otherwise check your CPU is running ok, I have same card, running at fx-57 speeds on cpu, wipes the floor with fear everything on high

The 7800GT was pulling 3500 on 3D Mark !

What PSU do you have, the x1900's use a huge amount of power, you might not have enough oomph to power it.

Welcome to the forums btw.

I ununstalled them but not with Drivercleaner - will give that a go+

i wouldn't worry about FEAR, it has rubbish engine that just never wants to run fast on any system, two words: badly coded

Hey - cheers for the welcome - got some good recommendations that people here know there stuff

I have a 450w PSU cannot remember the make

Any chance you can get the side off the case and tell us the voltage on the rails ?

CS:S isnt a good game as the 7800GT is already enough for the game. Id say your CPU is holding you back as its a very cpu dependant game. At 1024x768 full settings i get 144FPS average in the stress test. I also get the same result at 1280x1024. I'd say you really need to make your resolution higher.

I dont have a clue about fear or the bad 3dmark score though :eek:

What make is your PSU? And also what are the amps on the rails?
There should be a sticker on your PSU listening the amps on the 12v, 5v, 3v rails.

fullfat · 2 Jul 2006 at 12:15

is it a decent brand of 480w?
dont worry about fear, it tells me ive got a mdeium rig too with the x1900,fx55 2gb of ram etc, the games just a system clown.

There should be a sticker on the Power Supply it will have

+3.3V +5v

28A 32A

Those are the figures im after

EDIT : All of them if possible please, especially 12v

Mort2k · 2 Jul 2006 at 12:32

ok

uninstalled ATI drivers Ran Dirvercleaner for Nvidia and ATI, reinstalled latest Catalyst - same results on 35mark

the PSU is a Coloursit? volatage as follows

+12v +5V +3.3V +5VSB -12V -5V
16A 25A 25A 2.5A 0.5A 0.5A

I would look at a decent power supply Coloursit are very cheap about £8 i have seen them for a 450w psu .

fullfat · 2 Jul 2006 at 12:37

sounds like a cheap psu youve got there, and it also looks like its got half the amount of amperage on the 12v+ rail. that wont be enough to feed a x1900xtx mate, youre throttling it with lack of power im afraid. you NEED a new psu to improve performance

Cheers for the advice - never knew that the Voltages mattered so much, but it makes sense when you give it some thought !

Can you or anyone recommend a decent PSU for a sane amount of cash ?

Also

what Amps would you expect from a decent PSU ?

Thanks
