Help with a HIS ATI 1gb 5770

Hi All,

Apologies for a first post 'dive right in and help me' thing.... Am semi-new/naive to PC builds etc. My current build is my first.

I am looking for advice on a problem with my gfx card - a HIS HD 5770 1GB GDDR5, which I have ran for 6 months.

Over the last week, upon playing any games the card cuts out display after a couple of mins play. The PC still runs - its the graphics output that cuts. I need to powerdown and re-start. Windows runs fine - but no games.

I've used the card since Sept and it hasn't skipped a beat. Plays BFBC2, ME2 etc high detail, 1080, all fine... and it is completely standard - no o/c, fan changes etc.

In an effort to solve this I've since updated the drivers to no avail, reseated the card in my case, no change.

My case is cool - running 3 fans, CPU temp idles at 39c, GFX temps at around 46c
I've even left the case open for further cooling - but no change.

I've then scaled down the graphics settings on the games (resolution, AA, detail etc) - no change.

I then noticed with the case open that when the cut-out problem occurs, a red LED on the card lights up. On investigation this LED is labelled D4000 on the board.


Any ideas anyone - help is greatly appreciated!?


The rest of the PC is a phenomII 955 be, Gigabyte GA-MA770T-UD3 board, CiT 550W ATX PSU, 4gb DDR3, WD Caviar black 500gb & Samsung 1tb drives in a Thermaltake V3 case on windows7 64.
 
is it possibly a power supply issue?, ie not enough juice to your card
or a faulty 12v supply to the card
hence when put under strain it cuts out
just a thought

or overheating
 
I had a similar issues to this a while ago. The way I solved it was to go into control panel and faff about with the sound device settings, so that my sound output was "Speakers" as opposed to the 5770, worked for me :)
 
Cheers for the reply guys.

I've checked the sound issue - it does not appear to be that, I go straight from the PC to an external m-audio dual soundcard box. This is labelled as my sound device everywhere I can see.

First thought to me was overheating.... though the airflow through the case has been fine - the software temp readings are within a decent range.

Are you able to recommend how I test whether its getting enough power?

The PSU is 550w which I thought would be enough?


I am torn between reseating the sink on the card to make sure thats fine, or whether not to do this for fear of warranty violation and enquire about a replacement.
 
Wow - this forum moves quickly :-)

Just bumping this back up.

I still get the same error as before after trying various other changes - I've been getting and education on this forum since joining and am suspect of the CiT PSU (awful rep from you guys) that I have so have ordered and OCZ PSU.


I am just curious with the D4000 error LED on the GFX card. I've struggled to get much of an answer on google, or from mailing HIS.

Am hoping the powersupply will solve this - but anyone else got experience with the red error D4000 LED on their card?

It's not just a matter of your PSU being able to supply the wattage required but more over just how stable the 12v rail is that's supplying the current.

Remember a PSU delivers electricity using transformers (converts DC current from the wall and turns it into AC current that your computer can use), voltage rails, amps and wattage. If the 12v rail isn't stable enough and wobbles outside of the ATX spec that could cause your CPU or video card to cut out if the power it's getting isn't clean enough. Just remember wattage is only a mathematical conversion of volts X amps so with that in mind your 5770 requires 108 watts delivered on a 12v rail which means it requires 9 amps (108/12=9). Now if your PSU is faulty and the 12v rail isn't able to maintain 12 volts and only delivers say 10.5 that means your video card will getting 94 watts which isn't enough.

It could also be your CPU that's causing the issue as well, you might want to stress it with Prime95 for 30mins and see if cuts out (and keep an eye on the temperatures as well).
 
Thanks for that Freddie.

I've given my CPU a run for an hour on prime95 - no crash problems.

Have been having further reading on the PSU - there is no way to know really how stable it is unless something goes wrong?

Its a very budget 550w Cit and appears to have a bad rep here but hasn't let me down over the last 6 months until possibly now.

Its the D4000 red error LED on the graphics card that I cannot seem to track down.
 
The only other real way of testing your video card is to test it in another PC and see if you get the same or similar issues other then that you can risk an RMA where it will be tested and if there is no fault found it will be be returned back to you. I can't help you with the LED error I'm afraid you could email tech support at HIS and see if they know.
