Should I even bother crossfiring Vapor-X 5870's? - Page 2

With that MB spacing you should get the EF6 cards. I would even if you had more space, they are better cards IMO.

Damn, I could have gotten two of the eyefinity cards for about $15 more and they are 2GB cards, but getting a reference card scared me because of bad cooling/fan noise, not to mention having to buy adapters if I get more monitors.

I looked up the dimensions of both the vapor-x and the eyefinity 6 cards and they were listed with the same H X W X D. Weird.

I suppose I could get my money back, and wait for the Eyefinity 6 to go on open box again, but it took me a month or two between seeing those sapphires go on open box the first time and when I was able to buy them again.

I'm going to try crossfiring them again tonight and take some pics and if the temps are bad, I'll probably return them to New Egg while I still have the chance.

Sizzle, can you send me a link on how to make a custom fan profile? I'm only using CCC at the moment cause I didn't want to overclock too much with the heat issue. I'm pretty much a noob when it comes to OCing Graphics Cards Thanks.

Yeah, the reference coolers do much better when it comes to situations where the cards have to be sandwiched close together. For the $15 extra, they would have been good buys.

But for your situation, I would say to update your motherboard BIOS to the latest version if possible (even if it is a beta). Doing that actually fixed a problem I had with SLI due to compatibility issues between the different PCI-E slots on my motherboard, so it may be worth looking into.

It could also be something as fundamentally simple as reseating both cards. Even the slightest protrusion can be the difference between stable and unstable.

If it doesn't work then you may want to test out each card individually as it is possible that only one card may be faulty. However, if both cards test fine, I would look to trying a different Crossfire bridge. And if THAT doesn't even work, then it looks like Newegg owes you some money.

Thanks for the help covertash. I did try the cards individually and they seem to be fine. I'll try the Asus mobo update tonight and see if that helps. I'm assuming that will kill my custom clocks on the cpu/memory, but will my saved profile still be in tact?

I only have one crossfire bridge cause these cards were truly open box and came with nothing at all except the cd. I'm going to hopefully try all that tonight and let you know what happens tomorrow.

I doubt you'll still have your profile left as BIOS updates usually wipe everything out. What I've done lately is just take pictures of the different menu settings with my iPhone and refer back to them when I reset my overclocks. Most of the time, this works out fine, but there have been rare cases where my overclock had to be redone because it was no longer stable at the same settings. A small bump in voltage usually fixes that right up.

Best of luck with everything. Hopefully one of the above will resolve the issue.

First get either MSI Afterburner http://event.msi.com/vga/afterburner/download.htm# or Saphhire TRIXX http://www.sapphiretech.com/ssc/trixx/. With your cards I'm thinking TRIXX is your best bet as it is probably the only way for you to get voltage control also.

With Afterburner just click settings and the fan tab and check "Enable user defined software automatic fan control"



Now you will have the fan profile window open. Just drag around the little squares to where you want them. You can add waypoints (little squares) by clicking where the line meets the edge of the graph on either side.

TRIXX is pretty similar but just click fan control too bring up a similar window as above.



Sorry that's the only pic of TRIXX I have handy. The computer with my 5850 in it is down at the moment.

Sapphire Trixx should give you voltage control even though it is a non- reference card.

I have similar board. Running SLI or Crossfire on it can be a challenge. Rather it is doable for you will be a matter of how hot the cards run to begin with IMO. With my 460's the top card runs about 10-12C warmer than the bottom while gaming and it took a few minor adjustments to get it that low. Turned side 200mm from exhaust to intake, a more aggresive custom fan profile with quicker update period so that it responds faster to rising temps, installed with screws in the back panel to squeeze in an extra mm or so of room by not letting the top card sag at all like it wanted to. Not ideal but it works without being too big of a headache.



MW2 isn't a great game for checking temps because it limits FPS at 90 if I remember right. Doubt that would put one 5870 at 100% usage let alone crossfire.
90FPS on my 6870 at 1080P 4xAA ingame "full settings" (Not much to max), grabs 45% gpu usage.

Ok, so I think something is either up with the cards the crossfire bridge or the drivers. I ran the benchmark for Resident Evil 5 and only got 58 FPS max and got a B rating. I had my cards in crossfire and v sync off with no cap on frames. I checked GPU-z and the second card has a slight load of around 50/60 percent.

I flashed the Asus Bios to 1301 and redid my overclock settings. I then played left for dead and where it had crashed immediately before, I could now play for 30 minutes or so before it crashed. The screen would just freeze and the audio would be stuttering.

I had ran GPU-Z to check for temps and when I checked the logs the first card was in the low 80s and the 2nd card was in the 70s but both cards were at 99 percent load. Something has to be wrong here right? I had all settings max, but two 5870's shouldn't even break a sweat in this game...

Lastly when booting up the fans seem to spin at 100% and then go down after windows has loaded.

Should I just sell/return these cards? They seem to work ok by themselves.
I've also attached some pics of my GPU-Z logs and my crossfire setup.

It's just a hunch, but I would say as a last ditch effort, try running everything again at complete stock settings - no overclock whatsoever. Your screen freeze and audio stuttering seems to be hinting at your overclock. Let us know if you still have issues.

Not all games will fully support crossfire. You should check what kind of experience others are having with Resident Evil 5. It might be as simple as needing a driver update or setting a profile for that game.

Maybe your CPU overclock is not stable ? You should try running stock settings and retry L4D. I wouldn't be happy getting into the 80's but it isn't entirely out of line. Increase airflow and add fan profile to keep it under 80C.

Fans jumping up to 100% at startup is normal for some cards.

The increased hassle it takes to run dual cards isn't for everybody. Especially adding in the lack of ideal PCI-E placement on motherboards like ours. I don't mind tinkering with my system a bit here and there to see the substantial performance benefits dual cards can provide. If your not happy with the setup though just return/exchange them for the most powerful single card you can squeeze in your budget.
