Asus Radeon 3870 X2 1gb problems

I have just bought an Asus Radeon 3870 X2 1gb and am having problems running any 3D Mark benchmarks. Every time I disable the Catalyst A.I setting my computer would run it fine however I am getting a low score of 12990 when my computer performed better on the same system with a Geforce 8800 GTX and got in the 14000. However when I enable the Catalyst A.I to either standard or advanced I get higher frame rates but everytime it reaches the second test ( the firefly test ) my whole computer would just crash and restart. Why does this happen? and also Im hearing small buzzing noises around my graphics card. dont know if it is my card or something else on the computer but Ive never heard it before until I installed this video card.
I am running:
Intel Core 2 Duo E6850 @ 3.5ghz
Gigabyte X38 DQ6 Motherboard
4gb G.skill ram
2x 500gb Seagate hdd in Raid 0
Asus Radeon 3870 X2 1gb
Creative X-FI Platinum Sound Card
Gigabyte 800 watt PSU

yeah ATI cards dont like it when the processor is overclocked. All those guys running 3dmarks with overclocked computers and ATI cards (world record holders) are just hax and fakes it.

Are you running 8.3 CCC ?
If so it can have a problem with 3dmarks and world in conflict and company of heroes.

Try 8.2 or 8.1

8.3 has been messing up 3d mark 06 runs... maybe that could be the issue? though if it's making wierd noises, etc, i'd RMA it sharpish: that could be the tip of the iceberg.

hi there guys,
thanks for all your input. I have returned the video card back to the shop i bought it from and they replaced it with a new card. The buzzing noise has disappeared however it still suffers from the same sickness as the last card I had. Whenever Catalyst A.I is enabled, whether it be on standard or advanced, and I run 3D Mark 06 my computer will crash and reboot itself. I have made sure that I have enough cooling for the card and it runs at 50 degrees idle to 60 degrees when running 3D Mark. I have both 6 & 8pin connectors plugged in and have a gigabyte 800 watt PSU running on windows vista ultimate 64bit edition with 4gb ram. I know this is a good decent card but I have run out of ideas why it does this?! Is it a driver issue, or a card issue or something else?Please help?

Ok, I have the Sapphire version of the card and I've never had an issue, and my system is overclocked (CPU and Video).

I use Rivatuner to monitor the card on my 2nd monitor while I'm running benchies, and I can see when the clocks get ramped up, GPU load, as well as fan speed and temp. I mention this because you might be able to use this to troubleshoot the problem.

What version of 3dmark are you using? Is it 1.1, and is it pro? Does it detect the card correctly?

Does your system crash while running any other demanding 3d apps/games?

I'm running a very similar system to yours, but on 32 bit Vista without issues.

Yes you can add a 3870 512 for 3-way Xfire. It's been done alot.

You must use catalyst A.I. enabled if you want both GPUs to work. If there a strange noise coming from it, you may have a problem with the fan. In fact your crashes my due to a heat issue. I know my Asus 3870x2 fan was stuck at 25%, so during gaming and benchmark tests it would get pretty hot. However you can use rivatuner to up the fan speed manually (will get louder, but will also stay much cooler at 40-45%). To get rivatuner to work with the 3870x2 just google 3870x2 + rivatuner and you will get some guides. It's pretty easy, a simple change to a config file. Oh and don't expect much of a difference from 8800GTX to a 3870x2 in a lot of stuff, especially COD4 which doesn't like crossfire all that much.

theres already a hotfix for the 8.3's guys.

i just ran 3DMark 06 again with the graphics card fan running at 100% and i managed to run it a bit longer up to the start of the Canyon Flight test (one with the big dragon looking thing). it used to shut down at the firefly test but now it shutsdown at the canyon flight test. my card was running at 45-50 degrees on max load so i dont think its overheating. i made sure it had plenty of cooling and plus the room temperature was around 17-20 degrees. im still puzzled why it shutsdown. something is not working as its suppose to

hi firebird.. my cpu runs at 32 idle and 40-45 max load and this is at overclocked settings @ 3.70ghz for my E6850. i have a Thermalright Ultra-120 eXtreme with 2 120mm fans installed on the heatsink (push & pull) as my cpu cooling device. i also have sufficient case cooling consisting of 2 120mm intake fans, 1 120mm top exhaust fan & 1 120mm rear exhaust fan on my Antec P182 case.

ive also tried the benchmark on stock cpu,memory,graphics card clocks and it somehow shutsdown sooner. I doubt that my cpu is bottlenecking my video card, if so i also doubt it will cause my whole computer to shutdown.

Mine it does run fine Diamond ATI HD 3870 X2
Still waiting for the Phenom X4 3.0 GHz

Many peeps are missing the part where he says he's replaced the card, buzzing noise is gone, but problem persists.

I'm a little upset now. I just ran a 3dmark because I re-installed drivers the other day. System either locked or re-booted about 6 times. I reset the O.C. on the vid card back to stock, but problem persisted. I backed the CPU down to 3.6, and memory down, but problem persists. I then upped the CPU voltage but am weary and just want to use the PC.

I BLAME HUSBROWN! HE'S CURSED ME!

I am having the same problems with my Visiontek 3870 X2 and 8.3 Catalyst drivers. I RMA'd it and they sent it back saying that they benchmarked it and it functioned normally. Personally I don't think they could find their own ass with two hands and a flashlight. But I do hear a buzzing when the GPU is active. I also saw that GPU-Z reports that they are not CF and show up as two seperate 3870s. Another thing is that one GPU shows its default as 411MHZ and the other shows it as 825MHZ.

I know it clocks down to save power and heat, but I just thought it was odd that one GPU showed 825MHz and the default and the other showed 411MHz as the default (shows it for the memory clocks also). I have Cat A.I. set on advanced but it still shows them as not being CF enabled. Follow the two links in my other post, they are screen caps of GPU-Z for each of the GPUs listed.

odd, I thought it would have picked up some sort of CF, its 2 GPUs on one PCB with a PLX chip to interconnect that is running PCIe 1.1
The thing that is bugging me is that one GPU always stays at 411MHz and the other clocks up and down, from 411MHz to 825MHz. MSI said "it is stable" well of course its stable, there is one GPU running, the other one is running at clocks speeds that rival a radeon 9800.

I know its weird, and the thing is, GPU-Z show the rails powering up and down correctly, from like 5-8 amps to like 28-29 amps or whatever its supposed to be, maybe I am just paranoid.

amd overdrive is showing the right clocks, GPU-Z still shows crossfire disabled, but I am losing faith (quickly) in that program. My PC Power and Cooling 610 watt has an 8-6 pin and a 6 pin.
