4850 Crashing under load

[Plec]

If I could keep the card and flash the bios to a standard 4850, then manually overclock I'd be a happy bunny.

Thoughts anyone?

James/Jamus (can't remember), in the thread that i linked, was informed by xfx that this wasn't a possibilty for the 4850.

Plus, i'm guessing, OCs would have suggested this as an option if it was possible - as they are aware of this particualr probelm with some of the xxx 4850's.

Im 99% sure, it could be that the VRM Voltage Regulators are getting to hot.

Open Rivatuner hardware monitor.
and see what your VRM temps are under load

Run Furmark For 2 minutes and maximize GPU load 99% then come out of furmar and see what your vrm temps are. if there over 100c then thats the cause of your black screens

Good read Plec.

Right now I'm thinking:

Return card for Refund
Order new PSU and GT 260 or ATi 4670 Now
Enjoy on Monday

Sounds like a plan - you'll be happy with either card.

Why the new psu?

"Trying to install the ATi Tray Tool Happy, but windows 7 rc-1 is not allowing the low level driver to run as its not digitally signed. I'll see if google throws up a fix"

Search for Driver Signature Enforcement Overrider @ ngohq.com

Using that lets me run tray tools in windows 7 fine.

Hey Plec - first of all I totally appreciate the effort put in by yourself and others in sorting out this issue - just wanted to say thanks.

Np, hope it all works out.

My PSU is DEFINATELY an Antec Earthwatts 430W. So, the question is will it power an ATi 4870. My Spec has been mentioned already as you know, and the only thing to add to that is a USB powered LCD (Fusion standard) and 2 92mm Fans running at medium speed.

If the PSU is fit and healthy and performing at levels advertised -it should have no problems running that spec.

Have a read through this thread you may find it of interest - link

I have a Asus 4850, and dam does it run Hot, my main pc has a gtx280, an its no where near as hot. what are Ati using in there chip, old bits of filings ?

 

[StevenRaith]

Hmm, this is not dissimilar to what my GPU is doing when I play FEAR2 [at, I might add, Vsynced 60fps, constant]. It is also an XFX 4850 XXX.

Mind you, I rarely play games [and FEAR2 isn't all that anyway] so not really a massive problem. And I have slapped a TRAD + 120mm fan on it, which may have affected the warranty just a tad, so a moot point.

Minty - my 4850 idles at 37 and never goes higher than 65 under any circumstances. It's not ATI making hot chips, it's Asus using dirt cheap coolers, and jam as a thermal interface

Steven, when your computer crashes/freezes do you sometimes have a screen displaying vertical lines/banding of 2 differing shades of the same colour?

If you do, in this particular instance, the perverse furry doughnut, that is 'Furmark' is the app you should be running just to eliminate it from being the same fault as described in this thread.

It's a quick easy test and is the one app that consistently seems to freak out the 4850 XXX edition if it has this particular problem.

 

[StevenRaith]

Plec, as per hte other thread, Furmark is fine on my machine, although I tend to run it windowed so I can keep tabs on the GPU through Rivatuner or GPUz - I'll try a fulscreen test later on and see what happens.

 

[Minty-Linty]

My machine just freezes and I have to reset

Thanks for all the help guys, especially rollins for lending me your thread

Ive been holding out over the weekend hoping for a bargain on MM but nothings come up, so instead ive just ordered the XFX 260 from here, fingers crossed that will be less problematic

Hope the rma goes well

 

[daryll]

Well the 260 GTX arrived this morning, so far so good!

Had a quick bash on Far Cry and ran FurMark for about 20 mins, no problems, temps seem to level off at about 85C under load.

The biggest change though is the noise! At idle I cant even hear it with my case fans on low, ill have to give it more of a work out but so far it hasnt gotten much louder under load.

Now to see if ocuk will refund rather than replace

Did anyone get the shipping cost back from sending back their faulty cards?

 

[Plec]

They should have if they ‘requested’ it to be repaid and enclosed proof of postage costs - but only if the card is diagnosed as faulty by OC's.

I've always got my p&p costs back when returning a faulty product within the 28 day period – it’s never been a problem – but you do have to request it, they won’t refund it automatically.
