yeah looks within tolerances i guess. The newest version of the ati drivers must have not agreed with it as they made it crash a lot. i have uninstalled them and put the ones on the disk on instead and it seems more stable.

I think the newer drivers disagreed with it will give it a few days and see how it plays.

thanks

50 is a fair temperature so I wouldn't worry. I'm using 6.12's, heard bad news about the 7.1's so I'm keeping away!
 
Must be something else wrong with it at standard default speeds with no overclock or ati tools etc running on an unclocked cpu with case temps of below 28c it is locking up and crashing. runs desktop etc all fine but crashes during bf2142 but will also refuse to run second test in benchmark05 for more than about 15 seconds. i have pulled card and reseated it reinstalled drivers etc all to no avail. do you recomend RMA (or pain in the ass)?
 
I had to RMA my Gecube under the same circumstances, 4 games, 3 different drivers, patches on games would not stop it from locking up so far into games. I concluded it must have been a hardware issue, and sure enough when I sent it back they found a fault on the card which was a relief.

What PSU do you have? and what 12v rail values does it have?
 
just called tech support and they advised i upgrade my psu. now this is a 450w jeantech with a 35amp 12v rail so i am a little suprised this needs updateing to be honest any other thoughts
 
Jeantech? How much did that cost you? I haven't ever used one but I've heard they are pretty naff PSUs. Just done a google search on it and various forums have come up discussing their quality.

PSUs are the most important component in any computer system, I once bought a Q-TEC 550W for £30 and I had nothing but problem. Basically you get what you pay for. Its definately worth investing in a good PSU it provides power to your entire system and is the backbone of it.

Chances are that cheap PSU is giving you the problems! I would recommend, Antec, Enermax, Seasonic. (in that order). I have been using Antec PSUs for around 5 years now and they are rock solid. Get a 550W Trio like I have, they are brilliant!

With my Gecube I couldnt detect the temperature cause it didn't have a sensor, this powercolor has one though. Are you able to detect the temperature in overdrive with your gecube?

I've couldn't on the 6.11 or 6.12s, I haven't checked with the 7.1s that I'm using

Is there any way u can test the card on another machine. I know we all don't have multiple machines but perhaps u have a friend with a PCI-E system who don't mind it being torn apart? :D

Other than that it could be a faulty card, there have been one or two people having similar problems? It could be the PSU but the X1950Pro isn't as power-hungry as a lot of other recent cards.

What graphics card were u using before your upgrade?

nowt wrong with jeantech as such. they're just not meant for high end systems. i had my 400w for nearly 3 years and it that time it never missed a beat powering both a 6800gt and an x800xt during it's time. and it's silent too. :cool:

but the problem for me was it only had 17a on the 12v rail. and i'm sorry but i don't believe yours has 35a. even the newest 450w model on their webby has 2 12v rails with 14a & 15a on each respectively. now combined that is still going to be low 20s - i have no idea how you work it out. i know it's not 29.... :p
 
Erm if its got 2 rails then yes you combine them mate because the psu uses 2 rails for stability and power distribution. So yes you get all 29 amps depending on what is needed and what the psu gives out at the time. Rails just equalize the power it doesnt lower amps because of multiple rails.

Least thats what i have read from various places.

nonsense. :p

like i say, i don't know how but it's not as simple as that. for example my corsair has 3x12v rails with 18a on each. 54a right? wrong it has a combined total of 40a. i think you'll find all other psus with multiple rails are not just added up either.... ;)
 
The rails can at peak handle all rails at what is designated. Most of the time the psu give out what is needed and balances the load between the rails so hence my akasa paxpower 400w psu for the his x1950pro 512mb agp card im gona get tomorrow if its on "this week only" it should handle it. As its dual rail +12v one is 15a and other is 14a. The psu will provide the ampage if and when needed up to max of what combined rails can handle. Gibbo said it will be fine and many others said too as there quality psu's.

Nope.

http://www.antec.com/specs/TP3_550_spe.html

* +12V1, 12V2,12V3 maximum output 504 Watts max.

Thats 42A @ 12v.

You cannot in most PSU just add the rails together. Each rail can supply up to the maximum specified. But not necessarily all at the same time. Each "rail" is just a current limiter fed from the same source. There are a few exceptions, but they're few and far. The value to look for is the combined 12v wattage.

Take a look on the side of the PSU. What does it say?

Total wattage, 400W
3.3v+5V=200w???

Which leaves?? 200W or 16.6A for the 12V, in all honesty. Not good.

Tho it says +3 and +5 combined is 130w.

Regardless, gibbo said it will work and if it doesnt he is getting the bill. As im puttin my trust in him. :p Besides many users told me the same anyhow.

Well we will see anyhow how it will perform. As at the mo im using a asus v9999GE and that using a 6800 ultra pcb board with 2 molex connectors used. And the power for them cards isnt that much lower than the x1950pro so..

the jeantech i have says 12v1 17a and 12v2 14a having read it a bit more carefully it says 5v 35a (my bad eyesight in a dark and dingy case.) that said both those fidgures make no comment on which rail the pci-e connector is on so it has either 17a or 14a.

Is there a way of combining the two rails to give a better amperage as i have only bought this psu about 5 weeks ago when my old one went boobs up and if i could avoid spending anoth £80 i would quite like to.

Do the math (400-130)/12 = 22.5A @ 12V

Thats not so bad, still light, but good enough for a mid power system. My point is, a few simple calcs is all that's needed not the word of sales managers.

Think of it like this: A power supply has a 30A transformer in the primary. And 3 x 18A current limited rails.

So it could supply.

18 + 6 + 6
6 + 18 + 6
6 + 6 + 18

or even

10 + 10 + 10

Or anything in between. But no more than 30A in total. You can't get more out than put in. In fact, less!!

Tell me you didn't spend £80 on a Jeantech??
