Ambient is still higher than I'd like, but the ACs are beginning to assert themselves now that the exhaust from the rig is being escorted from the premises.
And I was about to suggest ducting those hot exhausts elsewhere, silly me!
There's no doubt in my mind BFL is working with the superior chip, as of now, but it certainly is amusing the "cost efficiency" in regards to the infrastructure of the rig itself. I say that never having ordered from them though, I realize others have varied opinions-and if I were in their shoes I wouldn't be smiling.
Although I tend to agree with the statement; if you're going to do something, do it right the first time.
Now if only I had ordered more chips/boards maybe I could lend them to you for full optimization!
EDIT: Looks like you're averaging 74.3gh/s per the advertised 60gh/s? Unless I'm overlooking factoring another rig in? That's damn impressive!
The average will take awhile to settle, and then it'll rise somewhat overnight with the colder air, but at this point I'd not be surprised if the final average is around 62Gh/s/module which would put us around 744Gh/s for our 12 BFL modules. When I first plugged them they were averaging around 55Gh/s with their ineffective stock cooling and heat trapping cases.
I'm also anxious to see Teal's final product. I think he can knock it out of the park.
Cheers.

BFL Minirig SC added. Posted: 11 days ago
Dear virtual shareholders,
bASIC-Mining is pleased to announce the further expansion of it's ASIC mining hardware with the addition of a Butterfly Labs Bitforce Minirig SC. The Minirig SC will be expected to add 480 - 500Gh/s to bASIC-Mining's rapidly expanding hashrate. With this new addition bASIC-MINING has increased it's hashing power to approximately 925,000 Mh/s.
Cheers,

This remains the most recent news item posted to BTCT. I'm assuming you're waiting to get the Batch 3 order to post another update, but I think the work you're doing right now on optimization is probably something worth publicizing - perhaps once you've got numbers from having gone through all of the BFLs.
Hi davos. Agreed. When I have solid numbers from the mods I've made I'll make a formal announcement whether we have our batch 3 Avalon to push us over the 1Th/s mark or no.
Cheers.

Ty. I've been building custom high performance computer systems for over 25yrs so most of this is second nature. I find BFL to be an enigma. I will not pre-order from the company because I thoroughly despise their business practices, but the gear itself is really some of the most capable equipment I've ever seen. Then there are cost cutting measures employed that I find to be silly on products at this price point which are holding back what are surely the most capable chips currently available.

I've just finished work on the last minirig engine and I'm happy to report that the only casualties are some skin on my knuckles(I hate spinning fans), 1 stock case fan blade, and 1 stock hsf fan blade.
I had just restarted bfgminer when I snapped that screenie so hashrate was still climbing. Also ambient is high around the gear(21c) as the exhaust from the rig is being discharged into the room and the ACs cannot keep up. All that said temps are down a minimum of 10c on all the minirig engines by simply exchaning the thermal pads for MX-2 and flipping the stock HSFs. I also removed the aluminum fan shrouds from the minirig as I don't think they're doing anything save adding noise. I'll report on performance numbers as they come in.
Cheers.

bASIC MINING should sub contract you out to BFL as a industry specialist and pay us in minirigs
You are THE BOSS !

I tend to disagree here. Drip feeding every little bit of news on the front page of BTC-TC just looks tacky and needy. Most who are in anyway interested will have checked out this tread for the finer points.
Major updates to hashing capacity or new equipment purchases are good times to release an RNS. There will be plenty more of these if all things keep heading forward as anticipated, and as such have a bigger impact.
Just my two cents worth

Thanks guys. I finished modding the other two singles and averaged the results after several hours of operation. The results are as follows:
This is with ambient temp ranging from 16c - 18c. The minirig had a portable AC blowing directly into it's intake during this time while the singles did not, though the singles have all the high performance fans and TIM replacement while the minirig was stock.
My conclusion here is that if it's possible to take down the minirig and mod one engine at a time while the others continue hashing it will be worthwhile. With this in mind I stripped our minirig.
This is with one engine out for modding...the other 7 are still hashing. Now BFL's choice of low profile fans for the singles makes more sense as there's not quite enough room for our high performance 90mm fans on 6 of the 8 minirig engines. Apparently they didn't want to source or stock two types of 90mm fans. There's also not enough room to replace the case fans with deltas. I'm thinking it may be possible to increase the space between the lower 6 engines enough to squeeze in higher performance HS fans and this combined with replacing the thermal pads with high performance paste should improve performance significantly.
Cheers.

Nice - It looks like you might be able to squeeze out another 'half a single' ~30 GH if you can cool those engines. They should have an option to just sell the engines and forget the packaging and let the geeks figure out the best way to mount a cool these babies.
