It depends entire on the airflow in the system vs. trapped heat due to the heat. I have one system that runs cooler with the side panel removed, and another system that substantially heats up if I remove the side.
We cannot cash out to banks if it is not during bank operation hours. Mon-Fri. We will be trying to do daily withdraws and in enough time so that you receive your funds the first or next day. If you do not receive your funds by Tuesday 5PM, please email
Two payments arrived this morning, totalling £32. Thanks!
You can only run 2 different cards if their in the same series, IE 5xxx or 6xxx
The problem is that every different series of card uses a different architecture, 40nm,50nm, ect and the drivers simply don't support 2 of those cards working together

Not true. My Windows 7 box is happily mining with a 4850 and a 5770.
^^^ how are you doing this?
Literally just plugged it in (the 5770) and let Windows install the driver for it. Both cards then showed up in GUIMiner. You might need dummy plugs (I have a monitor on each card, so YMMV). Make sure you have the latest driver from here - I'm almost certain that the newest ones will support 4xxx, 5xxx and 6xxx series cards.
Re: Official Open Source FPGA Bitcoin Miner (Smaller Devices Now Supported!)
Does anyone know if code is available for the DE2 (not the DE2-115) board? I can get access to those through my university, so considering making it a summer project.
just being curious - to me it looks like depositing BTC @ britcoin takes pretty long (around 3 hours). It says it takes 6 confirmations berofre BTC get credited to your account. When I do a trade on my own Bitcoin account I get to 6 confirmations within a good hour. Any idea why it always takes so long at Britcoin?
Never had that problem. I deposited last night, and the BTC were showing in my Britcoin account about ~20 seconds after getting the 6 confirmations.

What miner are you using?
I just started with two 5850's (non crossfire) and can only seem to get one recognized. The other sits idle. The motherboard I'm using does not support full crossfire and causes stuttering in gaming with xfire enabled...so I just disabled it thinking mining would work with both and I could still game on one. Using Phoenix on win7 x64.
Thanks!
Just using GuiMiner as it is easiest to configure, though I have used poclbm without issue.

Most likely you need to use dummyplugs or Linux. Win 7 does not allow to use 3d-functions on separate ati series cards. To be able to expose the second (or third, fourth) card for the mining program u use, they need to be run in xfire, which you of course cant since they are ati 4xxx and 5xxxx.
It is definitely possible to use 4xxx and 5xxx series card together. I dropped in a 5770 next to my 4850 and both work fine (4850=75MHash/s, 5770=183MHash/s)

Purely for mining, I'd go for the card with the smaller memory. They tend to be a little cheaper, and I suspect that it will save some power consumption. Downclocking the memory also has no effect no hash-rate, but can give substantial heat and power savings.
actually, downclocking reduce memory latency in Radeons case and for mining context thats far more handy, than throughput[which is matter in case of gaming workload/appz]cuz tiny amounts of data need to be moved VERY quick.Never noticed an increase, but I can see why it could happen. I'll have a play around with that later. Thanks.
I'm getting errors when I attempt to use poclbm:

Is it harmful to a GPU to push it to its limits for hours at a time?
Strictly speaking, it will reduce the lifespan of the card, but of the ~10 I've ever had, I've only ever had one die before I considered obsolete anyway, and that one was both over-clocked and over-volted significantly.
Is there a big difference in power consumption when mining versus not mining, or playing a 3D video game?
Mining vs. Idling - Huge difference. Assuming you have a 9600GT or a 8800GT (about the performance level you are getting), you are looking at around 80-100watts extra power consumption.
Mining vs. 3D gaming - I suspect that it will be more to mine than game, as mining will keep the card at 100% load whereas gaming will fluctuate. I don't expect this to be a large difference though.
Try doing "cd /Applications/poclbm/" before the "python ..." command. If that doesn't help, run the command with admin privileges ("sudo python ...", and it'll prompt for your user password).
I'd be surprised if one or both of those doesn't help.

not mining... I thought I read mining takes quite a bit of electricity costs that prohibit any real gain??? 
Depending on your electricity cost. Where I am, I get free electricity (and the PC is on 24/7 anyway, so the difference from idling to mining isn't that big).
