A couple questions about a Radeon card

[lowbrow]

I was checking up on the hardware comparison page on the wiki and noticed an entry for a Radeon 3410 card. Which is a mobility chipset.

I saw the entry listed the person was using a custom brook+ miner, and I cannot find anything on brook+ miners in general.
I have a 3450 card I'd like to use for additional mining, the card supports openCL and everything, so I don't see why it can't be.
The miners I try using for the card tell me the there is a cal mismatch, that I need 1.4.879 as opposed to the 1.4.675 I have installed.

So my questions are:
How do I update CAL?
Where do I find this brook+ miner?

The 3XXX series does not support OpenCL.

Did you see the 3410's efficiency? It's abysmal at only 0,074 MHash/J.
Some CPUs do better (e.g. Phenom II X6 1100T is twice as efficient) and still they're perfectly inadequate for the task.

Just forget that 3450, it's not going to work.
A very inexpensive 6750 card is an order of magnitude more useful for mining but still is barely strong enough to guarantee a single Bitcoin per week of 24/7 mining.

Yes I did see it and I'm still interested

You shouldn't be, 0.89MH/sec is not worth bothering with. It will make you about 11 cents a month. Then you have to pay the power bill for running this thing at 100%, which will be about 150Wh 24/7.

In other words, Losses, huge losses.

On top of this, mining on a laptop is bad, and can cause permanent damage to the laptop due to overheating.

Overall: bad idea.

I concur; laptop mining is totally unprofitable (same goes for CPU unless your stealing the hashing power).

GPU / FPGA mining currently are the only ways to be profitable (with GPUs having the best value for dollar atm).

If you are talking about bitcoin/intial cost then I agree with you, but it is not necessarily true if you have to pay a fair bit for your electricity. Where I live, the net gain per day for FPGAs is significantly greater than the gain by graphics cards. I am pretty sure I can make up the difference between the graphics card and FPGA in 1-2 months. (Though I need my graphics card for gaming, so that is not going anywhere xD)

FPGA mining cards are great for electrical efficiency (most run under 20w) but require a good amount of tech knowledge in terms of getting them up and running in comparison to most current GPU setup. Having said that I'm in a similar situation where my electricity costs are going up (stupid smart meters) and have picked up a x6500 FPGA miner as a test unit (mh/s vs power consumption). I'll definitely make a new post here once I get mine and journal how things are going with it!
