New card, same problem

So after the last one had been causing random shut downs during games i had successful RMA and Ebuyer sent me a brand new, sealed box, 5770 to add with my other one and crossfire. Yay!

Tortured it (the new one) by itself, still in disbelief after the previous experience. 30 runs of 8xAA maxed out Battleforge benchmark, 5 runs of Dirt 2 maxed benchmark, some red alert 3 maxed and crysis. No hickups whatsoever bar the expected low frame rates from a single 5770 doing all that work.

Pop it in crossfire. Everything's fine. Open up AvP. 20 mins of survivor and FFS WTF *BOOM* has crashed!!!!

Is it really possible Ebuyer have sent me a second faulty card (they confirmed the last one was)? I was really looking foreward to a functioning crossfire rig ready for my d-14 and excaliburs arriving friday. Looks like that won't be happening.

It's only happened once. But i've only ran a game long enough for it to happen (in crossfire) once. I will play a few other games in a moment to check it wasn't a one off but it's exactly the same conditions and exactly the same problem as before. Really can't be doing with another RMA

What drivers are you on? I have nothing but trouble with newer drivers and my crossfire setup. 10.10 and 10.9 works best for me, so i suggest you test if older drivers work better... The problem I face is framerate drop in many games, not all of them, but most older games like Grand Theft Auto and NFS Shift run worse on newer drivers...

If you are not shure if the card is faulty you should try to play with only the new card and see if it works just as well as you're old one.

Cheers mate! And good luck

Ps: Excalibur fans are pretty noisey, I have two of them myself....
 
I don't mind noise in moderation.

Nah it's exactly the same problem i had before and even ebuyer confirmed that was faulty. Think they have a pile of tat trying to palm off cheap before goes obselite. Asked for a refund this time, i'll put the measly £95 towards a 6970 (6990 is crossfire

). thinking of buying Starcraft II with some of refund as is supposed to rely on cpu a lot (4+ ghz overclock with d-14)
 
I'm sorry Fodr, I haven't read/can't remember your previous thread on this issue, so I looked at your profile to check your system specs.

Firstly, you're not really running with 1x stick of 4g ddr3 are you ?

But what I was going to mention was something along the lines of cpu overclocking. 3.2ghz doesn't mean anything to me as I've been without an AMD cpu for far too long, but is that a big leap over stock clocks ? Only reason I ask is that AMD's graphic drivers rely a bit more on the cpu than other makes, and if there's some kind of flakeyness, it's possible that although benching runs work fine, a prolonged gaming stint may crap out the drivers.

Can you try it at stock ? (if it's not stock that is)
 
sound to me like 1 of 2 things possibly.

1) ur drivers are causing issues in the xfire arrangement

or 2) maybe the psu's not handling the extra card as well as it should might be worth looking into as a possibility.

or I know I said 2 but this one came to mind

3) its like ya said a bad card but as you tortuered it I'd think one of the prior 2

Hope this adds something for you to think about

Yeah, single stick with 4 gigs, better upgradability. Never had any problems with that.

3.2Ghz is the stock clock. I'm aware of the cpu dependancy so haven't even attempted overclock and like i said d-14 doesn't arrive till friday. The thing is ebuyer found the other card to be faulty so the problem was the card. They'll more than likely find this one faulty too.

Planning to save up + the refund then buy a 1gig 6950, should give about the same frame rates as two 5770s and eliminate the micro stutter too.

A single stick means that you're forsaking 'dual channel' memory operation. With two in there it opens up a wider memory bandwidth (terminology?)and that means better performance.

A single card with better specs is what I try to do too. SLI and Crossfire mean that you have to 'tweak your games' to work the best with the dual card setup. NVIDIA and AMD both have 'profiles' that you can download for specific games to make them behave.

Is that why my memory shows as only running half speed? After watching Tom's 990x vid i thought all memory showed up like that and you just remembered to double it. Maybe should get another 4gig stick while i'm at it

do yourself a favor and buy a dual channel kit instead of buying another 4gb stick dc kits are matched memory designed to give best performance.

and yes cpuz shows it halved ur not wrong there were talking about bandwidth not what the cpuz shows

This was in overdrive it shows as half, but probs same error. It's the exact same stick i'm gonna get, so no reduced performance for buying seperately.

Am i right in thinking dual channel is faster than dual dual channel (8GB in two slots faster than 16GB in 4 slots)?

Not really,......I had 2-2gb sticks and added 2 more of them. I got a little better performance, but it was due to having 8GB instead of 4GB. Some systems required a little voltage bump to accommodate 4 sticks at once, but memory doesn't use as much power these days and most of that has been sorted out.

Very much so.

Kits are better for people wanting to do wild overclocking schemes, mainly as you rely on the manufacturing process keeping like-minded chips together ?!?!? Sounds bizarre, but there is logic in it.

If you're not planning on bustin-balls with your oc, the same stick from the same people will have the same spd info within them so that whatever the one stick will do, so will the other. Don't figure on breaking world records tho

Be sure and stick them in dual channel slots too. Sticking them in odd slots will still make your memory run in single channel. Slot arrangement is mobo dependent - the manual will show you towards the front.

You'd never use 8g in any case, only a tiny fraction of games out there (in conjunction with Windows) use over 75% of 4g. 6g is overkill.

It'd be strange if you changed the memory and all your problems went away

I wouldn't think a store like ebuyer would test kit. Afaic they're mostly sales staff, they'd just fill in a form and return it. Somewhere like Scan most certainly would.

I'm still upgrading to a single high end card though. Better compatibility and performance all round. I just can't be doing with endless bouncing back and forth of dud cards - refund, buy a monster, pop it in, future proof and works great.

That's a good idea, your reasons are sound, and it uses less power too. (usually)

I noticed, while the cards did work in the build up to dying each session, that you needed about an extra 10 fps than previously to counter the choppiness from crossfire. So 60fps on a crossfire setup may well be as smooth as 40fps on a single card as there is no gpu to gpu communication in the traffic.
 
Sweet.

Two cards aint worth the hassel imo. I'd always advise the best single card of around the same price of the 2 proposed xfire/sli cards.

Benchmarking is fine, real gaming it's just not worth it.
