Issues since installing crossfire please help

[Simon12]

Since installing 2 x 4870s in crossfire last weekend I have the following issues:

1 Sisandra (benchmarking tool) crashes as soon as I open it before even trying to run any tests.
2 Everest frequently makes windows freeze and I have to press reset.
3 Motherboard temps where between 25-33C regardless of activity now they are around 25-28 when windows first loads but when I exit a game they are high 40s and could have gone even higher while gaming. My CPU temps are not affected at all.
4 Due to the problem with everest (which is only 30 day trial anyway) I don't have anything to monitor the card temps as speed fan doesn't read them, is there any free software that will monitor them?

Despite the above I can play games fine with no issues (I have only played around 2-3 hours of Metro 2033 and 10 mins of modern warfare 2 but no issues).

System spec.
Phenom 550BE unlocked to 4 core @ 3.55GHz
4GB OCZ DDR3 1333MHZ (2x2GB)
Asrock 880G extreme 3
2 x Radeon HD 512Mb 1 is saphire 1 is XFX both 512Mb running 750MHz clock 900MHz RAM (i think this is stock)
Windows 7 64bit

Please help

Hello and welcome to the forum.

I am not up on the crossfire issues you are having.

But as far as the software to read temps:-

GPU-Z

or Hwmonitor

Hmm, I ran those card in crossfire for a while, I am on 5770s now. Which driver are you using? I have found issues with all drivers since 10.6. I suggest 10.5 Hotfix, most stable for crossfire setups. I would grab MSI Afterburner as this allows OCing of cards as well as temp read outs and FPS. Good bit of software.

Thanks for the advise, using GPUz Speed fan HWmonitor and Asrock OC tuner all looks OK when playing Metro 2033. I am running CCC 10.7 and I think I will stick with it for now unless games start crashing. I have a few more questions if you can help.
1. is it normal for crossfire to increase the motherboard temps buy around 10C?
2. the primary Saphire card idles at 500MHz and goes to 750MHz underload while the XFX card idles at 600MHz and according to the log file never went above it while playing metro 2033 (the Saphire card only went to 750MHz very briefly)is this normal or anything to worry about?
I should be getting Star Craft 2 tomorrow so I will see how that goes.
