Setting fanspeeds for XT1959Pro

Hi

I have some problems with a Sapphire XT1950Pro I have bought recently
I have heavy flickering on the screen during load
Running in the 2D desktop it seems to be stable if I choose 16bit and not
32bit

I have tried to mess around with fanspeed using RivaTuner and after setting
the speed to 50% fixed I can run eg 3dmark2006 without probs (gives me above
9600 btw)
Before messing around I was unable to the test due to flickering

I have read somewhere that you can increase fanspeeds - that is how fast the
fan is running at threshold temperatures
Any clues/ideas?
RMA is last resort atm

Unfortunately I was not paying prober attention and it looks like my
SeaSonic S12 500w is a little on the lean site for this card
I am bit unsure on this though - is the 500w ok for this card - or should
change to a more powerfull PSU?

Thanks/Peter

Is that the AGP version of the card ?
The AGP version has two Molex connectors.

http://www.sapphiretech.com/en/productfiles/168image5.jpg

But the chart near the bottom of this page, lists 65.7W, and suggests even
one Molex connector is enough. (If using both Molex connectors, you connect
a separate disk drive cable to each connector.) And even if they happened
to list the PCI Express version of card, the AGP card will only be a few
watts more (for the Rialto bridge chip). So that means the video card might
use 12V @ 6A or so.

Again, this is probably not exactly the same as your card. But
the reviewers here noticed they had zero overclocking room. You
can either view this as a "temperature" problem or a "frequency"
problem. Either the temperature must be reduced, or the frequency
reduced. Take your pick. If you don't like this, then RMA.

I had this card also and returned it. It appears either the design is
poor(which I believe to be the case after comparing it's cooling to
competitive models) or they had a bad batch of boards. Basically the VRMs
are overheating with the stock cooling profile whenever you do any intensive
3D work.

To mitigate the overheating problem I downloaded and installed ATI Tray
Tools(google it). Go to the overclocking menu item, there's a fan tab. You
can set a cooling profile. I basically added that at 50C the fan went to
75% and at 60C the fan goes to 100%. This makes the card stable. However
it sounds like a leaf blower. And who knows how long the fan or the card's
life will be with it running so hot. So I returned it and switched it with
the HIS model. Runs quiet and is 10C cooler than the Sapphire(and that's
with the fan at only40% as opposed to the Sapphire running at 100%).

If you are stuck with the Sapphire card and can't return it then I suggest
doing the fan profiling deal. There's also info on the Sapphire
troubleshooting forums about adding aftermarket heatsinks(to basically make
it like the Ultimate version). But if you can RMA it by all means return it
for a competitive model(suggest either the Sapphire Ultimate, HIS or
PowerCooler, all have nice cooling arrangements).

People on the Sapphire forums have been stating that it's a power supply
issue, that you are running too lean and that's the source of the
overheating. Counterpoint is one guy went all the way up to a 700W supply
and he still had the same problems. And with the rash of problems that
people have seen, where there's smoke there's fire. Check out the feedback
on the board on newegg. Not good.

Good luck!

Apperently something is wrong with this card
It crashed totally today

Very :(

One 3dmark2006 with 9634 and today no luck even in windows
So I returned it and switched it with the HIS model.

I could really kick myself in the but - I was considering another brand but
have been using Sapphire cards for a long time

The SeaSonic M12 700w gives 18A on 12v and the S12 500w delivers 15A or 17A
on 12V
Not much of a difference

Machinery is unusable anyway - I'll RMA the bstd and switch to a X1900GT or
a X1950XT - depends a little on the funds though
I have a Sapphire X1900GT running in similar rig - been running nicely since
Summer except for a minor accident with Chill Innovation PSU - well that's
life :)

Thanks for the reply
.... and Merry Christmas :)
