4850 + BFBC2 Crash

[Moose]

It may just be BFBC2 or any prolonged high gfx application, but it currently only has happened on BFBC2, and not Napoleon, AC2 or 3DMark.

Basically after half to one hour of play the computer crashes with a blank screen (no signal) and both LEDs light up on the gfx card, the only thing to do is shutdown and boot up, sometims it takes up to a minute to POST and the LEDs stay on.

I have actually had this problem before, the first time was solved by a new PSU, the second by cleaning dust off the heat sink, the third by taking the side of the case off, I am confident it is not overheating anymore, but I suppose it is possible that my new PSU is a dud (though its Antec)

Looking at HWMonitor graphs of voltage the only one that falls below the correct value slightly during intense load is +3.33V. Does that matter?

 

[overclocking101]

your gpu runs off the +12V rail the +3.33v has nothing to do with it. not sure though what would cause it. check your +12v monitoring.

 

[Moose]

+12v stays at around 12.3v and never drops below 12.2v.

 

[overclocking101]

yeah sounds like the card is thermal throttling for some reason thats why the lights stay on upon bootup. whaich heatsink revision is it?? do you run the fan at 100%?? also try pointing another 120mm fan on it while gaming just as an experimental basis. whats the temps?? and did you take the heatsink off and re apply thermal paste??

 

[OneMoar]

post temps @ load please ( anything below 90c is fine )
12.03 is just barely within Tolerance sounds like you MIGHT have a psu issue on your hands

12.3 and 12.03 are very different.

 

[alexsubri]

How many watts is your PSU? On your profile it says 650 watts, which should be fine. However, if you are running Crossfire, then it be pushing it a little since 4xxx series consume more power than the 5xxx series

 

[Moose]

Runs at 80c with side of case off (90c with it on)

Voltage is 12.3v not 12.03v to confirm.

It has the better gold heatsink not the flat one, I have not changed anything with it.

One thing though I can't seem to update the BIOS it doesnt recognise the card.

12.3 is fine ... The gold heatsink is not working? That may be the cause then. You need to keep your graphics card cool always. Even tho 90c+ can be normal, your burning your lifeline.

I would contact the company where you bought the card..

Last, you said it can't recall your cards name? As in GPU-z? Does it list the card correctly. Make sure you have your fan enabled to at least 40-45% and see how it's going after that...

Edit: Did you buy the heat sink as in aftermarket cooling, if so..maybe it's not installed right becasue the heatsink should lower the temperature A LOT

 

[overclocking101]

maybe take a pic for us?? also try and tighten the screws, sounds like your vregs are overheating to me.

 

[TheMailMan78]

I agree. Its ether a PSU issue or a power issue. Do you have another PSU to try?

 

[Moose]

The heatsink is a factory supplied one, it's just the better factory supplied one. To confirm, I have not yet edited anything to do with the heatsink, except putting the fan at 100%.

I have included pictures of the card and also some stats when running at load.

GPUz recognises the card but BIOS updaters dont.

I have no better PSUs they are not able to take the load.

Do you have a copy of the card's BIOS? Did you try Flashing at all??

 

[overclocking101]

sooooooo here is your Poblem(s)
1: that heatsink is good yes but it does not cover your voltage regulators AT ALL they are probably overheating slap a 1200 fan over that bitch
2: your gpu core is throttling 90c load is at the throttle point.

take the heatsink off re apply thermal paste use the 120mm fan. My best personal advice is buy an aftermarket heatsink. but if you can afford a good one, like a thermalright trad2 or something like that then try the 120mm fan pointed in front of it closer to the powerconnectors this way it blows on the vregs and helps move some of the gpu core air as well.

 

[Moose]

I put some artic cooling paste on the gpu, gave it a good old dust, removed the annoying plastic thing on the heatsink blocking air flow, and put a 60mm fan pointing at the right hand side of the card. Nice drop in temperature.

My BIOS: http://95.130.11.112/publicdownloads/bios.rom

Ill now test it out to see if things have improved.

EDIT: Damn still crashes

 

[Moose]

Soz for double but i think it's needed:

After doing even more research, I saw some guy on the internet mention that the problem may be caused due to the system thinking you have more VRAM than you do, mine thinks I have 2GB when it actually has 512MB.

Another thing is a BIOS update on the ASUS site (which I can't run) says: "Fix game may be stopped automatically due to graphics card is overheat."

 

[Rik55]

That ASUS BIOS update won't be for your card. It was for a very specific limiter batch of parts with the Part/Number: of *-C3CGG0-* & *-C3CGK0-*. These numbers will be on the box your card came with. If it doesn't flash it, it's not your card.

I had a look at your BIOS. Is that the original BIOS your card shipped with?

 

[overclocking101]

what are you trying to run the bios update with?? are you using atiflah or atiWINFLASH?? with atiflash you can force it to flash whereas winflash you cannot. Also dayum that did cause a huge temp drop man!! 30c is one hell of a drop. now what do you mean by it thinks it has to much ram?? on the gpu?? can you show me where it says 2gb??

 

[Moose]

My BIOS is http://techpowerup.com/vgabios/20205/Asus.HD4850.512.080523_1.html so no it wasn't shipped with my card.

ATiFlash isn't compatible with 64 bit windows so Im using atiwinflash, thanks for info on the ASUS one, my card is -C1CL50-

DxDiag says I have 2GB of mem:

Yer temp drop is pretty good had some crappy old solid stuff on before had to pick it off!

 

[Hellfire]

Yeah it says you've got 2gig of memory as it looks like you have hypermemory/shared memory. aka using ram as memory.

Dedicated Memory: 505 MB
Shared Memory: 1791 MB

= TOTAL MEMORY - 2296 MB

Shared memory is where it is utilising ram as video memory

 

[brandonwh64]

My 5850 throttles when it reaches over 75 deg and starts skipping and doing short freezes. when i play games i run my fan profile on 50% and it doesnt get over 62 deg full load. i suggest a better cooler on the video card or maybe replace the card with a 5770?

 

[overclocking101]

atiflash is a DOS based flashing tool, cant be used in widows at all, you need to make a usb stick bootable and add the dos files and ati flash files and bios file. then you can force it to flash, but if you disable in bios the memory remapping/sharing it may take care of your problem

 

[Moose]

There is no option in the BIOS to disable memory remapping/sharing, I have tried all the settings to do with the integrated graphics.

As for forcing it to flash, what with? (As in BIOS)

 

[Rik55]

There is no option in the BIOS to disable memory remapping/sharing, I have tried all the settings to do with the integrated graphics.

The shared memory is part of the DirectX specification for texture caching and isn't user accessible. Everybody has this.

 

[Moose]

I RMAed it Ill get a 5770 as a replacement, if that crashes too, well then we know it's my PSU or MB.

Thanks for the help!
