It's not that bad, it's just changing R1 and the crystal. The stock crystals needed to be removed anyway and they're quite a pain to unsolder for the first time, now I've got leaded solder on there when the new crystals arrive they'll be much easier to swap out and hopefully with the extra cooling I can get them to run at twice the speed they do now. Right now I'm running them with extra heatsinking and fan cooling.

Twice 360Mh??

Hopefully, bluestreak66 was saying the chips have a theoretical max of 1GH/s and that around 750MH/s would be the limit of these boards. So hopefully I can get these higher frequencies going with water cooling and decent power supplies. More for fun than profit of course. I'd like to think I can get the BE's to pay for themselves in a year and they'll need all the help they can get.

I had mine strapped to a heatpipe cooler, with the soldermask removed and the silicone sheet in between they were running quite cool at 447. Given the shortage of avalon chips right now these might just turn out profitable! I am quite curious why your only getting 360Mhs that seems low to me.

Here's my current miner output at diff 4. I'm looking at the avg as the device speed. ICA 7 is the only one not modified as a reference.

What crystals are you using and what resistors? you have some nice low hardware errors

Can somebody tell me what types of resistors these are? What keywords and descriptions to look for?

I'm using 1.5K (in an 0805 package) as R1, and the 16Mhz crystals are from a chinese eBay seller. I've got some 16Mhz, 20Mhz & 24Mhz crystals coming from Digikey and will replace the current crystals shortly and post the results. I'm looking to get the same speed Bluestreak66 has reported with a 16Mhz crystal.

Be aware that not all resistor are created equal most are 5% and good ones are 1% but some off ebay can be factory seconds and be off by 10% or more. If your getting them off ebay check the resistance before soldering them to confirm it's correct. Here are the ones that I've been using http://tinyurl.com/lzpfjbr

If you are using bfgminer these should appear as BES (Block Erupter Sapphire), instead of ICA (Icarus). But you need to "brand" your block erupters for bfgminer to recognise them properly. There isn't much difference, except the settings and timings are slightly tweaked for optimal performance. See: https://bitcointalk.org/index.php?topic=250326.0

they are different package sizes example: 5032 = 5.0mm X 3.2mm <--- the size on the erupter 6035 = 6.0mm X 3.5mm 3225 = 3.2mm X 2.5mm

I've got enough to overclock and test , I may be new here but I'm not new to modding(Team Xecuter anyone?). I will post my results as well, should have my stuff on Wednesday.

ordered the 16 and the 13.5Mhz. resistors shouldn't be an issue. I will see what happens once they get here.
