Is there a compatibilty problem with the ATI 4850 and Furmark?

Np Ransy-Pants (gotta love your name) hope you get a better result when you next venture out to buy a gfx card.

I had a look at the other 4850's on the site, they look good however everything about them scared me, single slot PCIe2.0 sent shivvers down my spine

As i have given up on the xfx i was about to order the Asus or the Sapphire version - is there an issue with single slot PCI-e 2.0 cards - heat, speed? I don't want to be returning yet more cards with known problems.

Thanks for the comprehensive reply, Ransy-Pants, it's appreciated especially, i suspect, with revision time now at a premium. Good luck, btw.

Armed with the info you gave me, i researched a bit more in to the 2 cards and found out that the Asus 512mb version now comes with the Glaciator Heatsink just like the 1024mb version and this seems to have improved its cooling greatly. It idles at under 40 degrees and, apparently doesn't break into a sweat under load - cooler than the xfx if reviews are to believed.

You were right about the heat issues but it looks like some companies are reacting to the criticism - Asus have so they will get my money. I just need to confirm that OC's carry that stock type before i order. That is of course after they've confirmed that my card is faulty - Royal mail has informed me that OC’s have received the card but it's not logged in as received, yet, at OC's. Hopefully they'll get it logged in and tested tomorrow and i can move on.

I'll let you know my views on the card when I’ve had it running for while - if it's as promising as it sounds it should run as fast as the XFX xxx once clocked.

It was tempting to get a 4870 but because the XFX xxx edition was so cheap the extra jump of £50-£60 didn’t seem worth it. But it always seems tempting to upgrade your original choice when you've rma'ed a part. It's almost as though you feel the need to reward yourself for all the stress you had to go through to identify one duff component - which, more often than not, you suspected right from very the beginning.

Good luck with your studies and exams.

You obviously have a problem mrh2019, but this thread is about a specifc type of freeze with Furmark.

The problems we're experiencing are in Furmark and Crysis. After running Furmark or playing Crysis (between 10 and 30 minutes) the computer completely locks up with the screen displaying vertical parallel lines of 2 different shades of the same colour. We're unable to escape the application/game - we must manually do a hard reset.

Have you had anything similar to the above?

Hope you get it sorted.

Mine arrived yesterday at about 12.30 according to Royal Mail but the OC's web site still hasn't recognised it as recieved yet.

I rang them and it just means that they haven't got to processing it yet - so just a waiting game now. I'm hoping they'll get to it today but i suppose it depends on their back log.

Plec
 
Thanks, TB, i'll stop checking and assume they'll e-mail me when they have a result.

Correction, it's going through the testing procedure as i type (according to web update) - hopefully have a result soon.

N1, pyrophonich - what are you getting in its place?

Well, OC's were really quick to test and they've issued a refund so i'm now looking very hard at the Asus 4850 512mb version which now, apparently, comes with the glacier heatsink/fan.

pyrophonich, i'm not an expert on the comparability of those 2 cards - but i do know that the 4870 tests well against the 4850.

Ok, i've ordered the Asus 4850 512mb, the new glaciator heatsink version (it looks like the 1024mb vesion if you want an image) - so heat shouldn't be an issue even though it's a single slot card.

Hopefully, this time monday evening i'll be tidying my case wires with 'plastic pull ties' rather than balancing my whole rig on anti-static sheets and cardboard; component testing every part to the n'th degree...

I'll let you know my opinion of it for those of you who are still making their minds up which card to replace there xfx with.

Guys, so you don't get into trouble - forum rules are that you can't mention competitors names.

Jammy, you have mail.

Plec
 
pyrophonich, read my last post as you may have missed its content answering Jammy's question. You can't mention other company names on these boards as the forums are run by Overclockers - they get a bit sensitive about competitors being posted on them - you probably didn't realise.

No harm no foul if you just edit it and delete the companys name - then the mods wont get upset.

N1, pyrophonich glad to hear you got a good result.

My asus 4850 with glaciator fan/heatsink arrives on monday hopefully i'll be whistling a similar tune.

This is deff is my last xfx product - i haven't ordered one that's worked in 4 years - i know i've been unlucky but even so...

Plec
 
I've opted for the Asus 4850 512mb version that now comes with the glaciator cooling system which has fixed all its cooling issues - 35 degrees idle and 50 - 60 degrees under stress. In fact if reviews are to be believed this version is now as cool as the xfx and the core is easily clocked to 700 (look at the 1024 mb version for a picture of cooler it now uses). You'll need to check that the place where your buying it from has that particular version - as if they have old stock it may have the original less efficient cooler.

If you're thinking about stepping up to a bigger card it depends on your spec and what resolution you have your sceen set at etc. If you have high spec machine and run high resolutuions the the 4870 may be a worthwhile upgrade but it will cost you a minimum of £50 extra compared to the xfx 4850.

I wish the card had worked not just because of the hassle it caused identifying the problem but because it would have proved to be exceptionally good value.

Well, my new card arrives and it seems to be working fine - so far.

However, the memory errors i was getting have not dissapeared as i had hoped. I was hoping they were a result of the faulty gfx card crashing the system all the time and that was why i had to keep clearing the cmos but now i'm not so sure.

I either have a problem with my memory or the motherboard. What's wierd is if i clear the cmos memtest works fine but after a few re-boots it seems to become corrupted again. I'm going to have to do yet more trouble shooting and a separate post on this issue.

I can honestly say now without any doubt this build, out of about 30 odd over the past 10 years, has got to be the worst. I hate this machine - it was meant to be a bargain upgrade, one that would box well above its weight with clocking but it can't even run at stock speeds without causing problems.

Back to testing - but it looks like i'll be rma'ing either the memory or the motherboard.

Totally demoralised.

Ignoring my above problems in the post above...

The card is brilliant clocks upto core and memory clock to 700 and 1100 respectively without breaking a sweat. The only downside is that the fan on this thing is quite noisy even when idling at 50% - but who cares as long as it works.

I may load on the Asus apps as i may be able to lower the default idle speed of the fan.

Furmark and Crysis absolutly no problems - and the card appears to just as fast as the xfx 4850 xxx.

Ok, fun over - back to trouble shooting the memory/motherboard.

Additional: despite all the problems i've had OC's were brilliant with refunding my card and postage etc - at least that side was painless and fast - thanks.

Yes, it is because on paper it's a great value card. Unfortunately, it does sound like you have the same problem as we all had.

As already mentioned in previous posts i've replaced mine for an Asus 4850 512mb the Glaciator version (just look at the 1024 mb version for a pic). It comes as standard on all the latest stock of this card so you need to ring the place you're buying it from to check that they stock that version. I only mention this as it only cost me £10 more - and essentially it is the very same card and very clockable.

Mines clocked to 700 and 2200 without any issues at all - and it still doesn't go above 75 degrees. The only down side is that it's quite loud compared to the xfx but i'm trying to sort that through the ATI CCC.

Good luck

Sucks having to return items :(
Click to expand...


It really does - i had to return a gfx card and then the memory on this build.

On the plus side, OC's turn around was really fast. On receipt of the item they always took less than 24hrs to test and refund - which, in my experience, is fast. So it usually only took 3 days for my replacement to get to me (excluding weekends).

Good luck with your return - at least you can be fairly confident it is faulty with all these other similar posts - that will hopefully be at least be some comfort.

Hi, I have the XFX 4850 XXX And get infrequent lockups (frequent enough to severely aggravate!) when playing some games such as Left4Dead. Can I run the crysis demo to test if its the same error you chaps have? And if so, RMA?

WinXP, if thats an issue.

The problems we we're having we're specific to crysis and furmark - but only because most of us didn't get to test other games or apps because these were the first games/apps we tried on set up - so you may well have the same problem.

I would install furmark as this is the easiest fault to replicate - if, indeed, it is the same problem. I would then do a crysis loop test, regardless of the furmark result.

It seems a specific problem to some xxx edition cards - probably just a duff batch. It can't have been many though otherwise my thread would have been inundated.

Edit: And obviously check your temps...

You might want to consider upgrading to the HIS ATI Radeon HD 4870 512MB at only £98 as it's great value and only £13 more - link
 
I've answered in the other thread.

But yes if your experiencing the same graphical anomaly, as mentioned above, in games and it replicates the same problem in furmark - then it's very likely you have a duff card - sorry. :/ (and if you've had it less than 28 days consider the 4870 at £98)

Does anyone know if OcUK should cover the shipping cost of me sending back the card? Cost me near a tenner to send it, and they replaced it with another broken card!! Which I guess I now have to send back, AGAIN, leaving me out £20 and with NOTHING to show for it.

Really ******* disgruntled about this.

They should repay both (they're pretty good about it normally):

You will have to ‘request' it to be repaid and enclose a proof of postage costs - but a credit will only be authorised 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.
