UD5 Crossfire

[Dunners]

I have two cards in CF on a UD5 board. It was a pre-build so apologies if this is a stupid question - They are in slots next to each other but the top one is getting very hot. Is it possible to move one to a slot further away?

Cheers

 

[Dunners]

Top one was up past 80 degrees after about 30 minutes of playing DIRT2 - it seemed to be slowing down and struggling so I figured that it was due to it being too hot.

I'll take pic tonight when I get in but pretty sure there is no blockage. I'ts all in a HAF932 btw

 

[Dunners]

how many pci-e x16 slots your board have?

Im not sure - its a Gigabyte UD5. Does that help?

 

[Dunners]

ok thanks v much I'll move the card and try to find where its been discussed before...

 

[Dunners]

I have two Sapphire 5870's in it.

What is considered too high in terms of temperature then!?

 

[Dunners]

I think both are in x16 slots at the moment - was an OCUK pre build so I assume theyd use those. From what I have just read there are 2 x16 slots on the board.

The suggestion i just had above was to move one to a slot further away - but would that mean one will run slower?

 

[Dunners]

80c is fine..

be worryed at 95-100c+

Blimey well maybe I dont need to worry then!

I wonder whats causing the slowdowns in games then...

 

[Dunners]

yes.

That aint too good then

 

[Dunners]

is your system overclocked?

Yeah its at 3.8 - courtesy of OCUK

 

[Dunners]

What speed is the other slot? If it's 8x tbh the temperatures are more important.

Yeah apparenly on a UD5 the other slot is x8

 

[Dunners]

If 80 degrees isnt an issue that eliminates that as causing the slowdown - so no need to move one of the cards

 

[Dunners]

ohhhh another pre-overclocked system from ocuk that isn't stable..

try everything at stock first mate

Yeah it seems like that must be somthing to do with it then.

Ill give that a look this eve

 

[Dunners]

Mind you they did say it was running stable for 20 hours before they shipped it to me (it had to go back 1st time due to faulty graphics cards - both 5870s were duff apparently!)

 

[Dunners]

If the other slot is 8x I say move it. Running cool the first card is less likely to die, the fan is going to spin less (quieter).

Yeah if the performace loss isnt that much I think Ill give it a go, assuming the bridge still fits.. I dont like the sound of manually setting fan speed etc

 

[Dunners]

The Std bridge is not long enough i have tryed it also to save you the headace you might find that the dual cooler design will not seat in the 3rd pci slot because of the pwr/sw connections on the motherboard are in the way. if you feel ok the best way to reduce temps and keep the speed is change the GPU paste to mX3 dropped my temps by 10c laod

Knew I should have gone with the Rampage II! Might try to find a longer bridge...

What you suggest sounds a bit complicated for me!!

 

[Dunners]

Why don't you like the sound of it? It is as easy as a few clicks of your mouse.

I might give it a go if there is no risk/side effects...I'm a proper novice at all this though - not had a pc since 1998!

I have two 5850's in a UD5 and the max i've seen my top one get to is 72c. That was on a warm day, benchmarking in crysis for quite a long time. Otherwise, i don't usually go higher than 68c.

Yeah mine are 5870's but from what I'd read, I did think my temps were a little high considering it had only been on for like 30 mins

I'll run a crysis benchmark for a couple of hours and see if anything melts i think
