You're fooling the hashrate meter into showing something stupid. The work utility WU rate is still consistent with a real hashrate of 336.
Cool that you can do this, but why use them anymore? Upgrade!
Unfortunately, this appears to be wrong. While the port speed settings did improve things slightly, the timings only affect the reported speed, not the actual.
I took one of mine and changed the timing to
Stock hardware.
Edit: Five of them are running at 500-550 Mh/s. Hardware errors are still in acceptable ranges.

--icarus-options 115200:2:2 --icarus-timing 2.0=75
Now it's averaging about 520Mh/sStock hardware.

Is that according to the pool you're using or the mining software?
That's an interesting question. I'm only able to see reporting from one of them (mining for other ppl right now too).
Miner shows 500-550 Mh
Pool live stats show .5 Gh but exactly 2x the submits the software is reporting
Pool history shows payouts for .3
Pool used: Bitminter
Tried another pool, and it's showing 100-250 Mh/s, so I don't think it's accurate.
Pool used: miningpool.co
I'm going to wait a couple days and try more of them in a larger batch.

How long do you think it will be until we get to try out your modded software?
All aspects considered, using:
--icarus-options 115200:1:1 --icarus-timing short=90
instead of:
--icarus-options 115200:1:1 --icarus-timing 3.0=100
Should provide most BE users with a slightly higher overall hash rate, more Accepted shares and a higher WU value to match.

Have you compared what's being reported in cgminer to the actual hash rate on your pool?
What you're seeing in your mining software is not your true hash rate.

Agreed - my miners are still showing the correct hash rate at my pool not the 'overclocked' rate and I left them running for a good 8 hours with these settings.
Depending on your host / set-up and the mining pool I'm fairly sure that there is a slight increase in the overall hash rate.
It is certainly not as high as the hash rate that appears to be shown in my original post, hence why I refered to it as 'an illusion'.
The actual speed is probably similar or less than that posted by Raptor2213
...
Mine are using the OP's configuration (minus the custom cgminer) and are holding steady at about 397MH/s.

The real question is can these settings generate more Accepted shares. I'm fairly certain that with some set-up's using stock block eruptors - they do, but again it is highly dependent on the host and the individual set-up.
Some of my own rigs are seeing more Accepted shares at various pools with a higher WU rate. I'll continue testing and moding the block eruptors and software. I'm certain its possible to get faster stock speeds with BE's, because of something else that I'm working on.

A little off topic regarding the fan pictures, but would a long metal heatsink with the lower part sitting in water work better than a fan? Or would there be water/electrical issues?

I don't know about OP, but I've found that one of these makes them cool enough to touch without any difficulty. From what I've seen from others, its a pretty standard fan to use on these setups. Newegg is currently out of stock, but they're also available on amazon - for about twice as much.

Most setups look more like this:
Mine will too - eventually.

That is a sick set up! (The 4 USB blocks with a USB fan)
Are you running with: --icarus-options 115200:2:2 --icarus-timing short=90 on those ?
Has your WU value increased ? Are you getting more hardware errors than stock settings ?
Thanks.

I am running with those values.
Before this, I was using bitminter's stock software, as I found it gave be better results than BFGminer, so I wasn't tracking my WU.
It looks like I am getting more hardware errors than stock, but tracking shows that my overall stats have gone up by about .1-.2 GH/s.
I'm interested in seeing what it will look like with a modded cgminer.
I'm using an Arctic Breeze fan for my block erupters too. It works great!

You doing anything special to cool them? They seem to run really hot even at the default speed.
Nope. I probably should do though. I've just made sure that they have adequate spacing in my hubs.
I do have a fan on my main set-up and after running overnight on 2 sets of 4 BE's, one with a fan and one without, the 4 with the fan do have slightly less hardware errors, which could just be a coincidence of course.
These seem to be the best heatsinks that I can find:

One of them on the main BE 100 chip and a good fan is probably all you really need to do. Although the main heat source is actually from the back of the BE chip, so replacing the main heatsink on the back is best when using moded chips.
