Are there any GPU which are economical that get less than say 100 MH/s?
6670... not really economical but they need no extra power.

What about AMD's APU processors?
Your point being? Those APUs do support OpenCL but there are no good boards for them - being targeted at the econo crowd, the mobos are low-cost microATX devices. It makes no sense whatsoever to use one in a mining rig, especially since the integrated GPU is pathetically weak.

I recall seeing a board that supported the processor, that also had 3 well spaced PCIe 2.1 X16 slots, and 6 RAM slots DDR3. I think is was made by MSI?

ASUS F1A75-V EVO has three PCIE slots. Still, the board and APU are more expensive and far less flexible than the epic MSI 890fxa-gd70 and a Sempron 145. The strongest Llano is still weaker than a hd 6570 which itself is by no means a card suitable for mining. Why bother?

I would point out the 3850 APU get 60 MH/s. Any GPU (or CPU for that matter) with speed fast enough to complete 2x nonce range between average LP is unlikely to have a very low efficiency. Even w/ 3 LP per block that is only 40 MH/s. For those with speeds > 1x nonce range per LP and 2x nonce range per LP efficiency is kinda hard to guestimate because a lot might depend on variance.
Still we are more concerned with botnets consist of everything from Pentium III to modern CPU and some of those CPU get <1MH/s. Thus their efficiency is something like 2%-5% range. No modern rig should have a 5% efficiency, or even 10% or even 50%.

Understood. However, it is also my understanding from an underground site I occasionally peruse, that some botmasters have figured out remote GPU mining. They set up the drivers and APP SDK to auto download on update, get the python or other dependencies, and run a dumbed down daemon to hash away after system has been idle for x-time. They troll sites where gamers hang out bragging about their hardware, and if they have an ATI card, they just ping the ip from the forums, and go to town. That is another reason I like Doc Haribos Java. It dont hide from you.

I’ve actually gotten security warnings twice from Symantec on cgMiner.exe now. So apparently cgminer is being used form something malicious out there.

its used to run on botnets. Its old news, most AVs have been warning about most miner apps for some time now, for this reason. The better AVs give a correct warning, stating the app is potentially unwanted (which would be the case if your machine was infected by a trojan and running a miner without your knowledge). Unfortunately most just call it malware or a trojan, even though cgminer by itself demonstrably is not.

My fanless HD 5450 does 15 Mhash/s.. Don't make fun of it -- when it found a block in May, it paid for itself many times! Perhaps I should go back to mining solo on that one. Luck may strike again!

IN may difficulty was roughly 1/10th what it is now. You were extremely lucky then, youd have to be extraordinary lucky now.

Meh. You get pissed off too easily. While bitminter server was having trouble, I temporarily moved to eclipse. My first full block there was 8M shares and in the next few blocks, there were 3 more 5-6+M share blocks without a single truly lucky one. https://eclipsemc.com/block_stats.php (Ii started at their block 446).

looks like he left early He pushed up to almost 40 GH/s, then stales started rising. What I found strange is that the new server isn't breaking a sweat, and still things slow down badly when the number of requests per second goes over a certain point. After watching the logs and numbers for a while I've located several bottlenecks in my programming. I hope to have a new version of the pool back end up sometime tomorrow. It should be able to make full use of the more powerful server.
