Do you still need a heater during the Winter?
What is the total power? 1.5 kW? over $100 on your monthly power bill, I guess

Just wondering: Are you guys actually buying these computers to create your farms?

I guess that is smarter than borging old machines, because of the performance per watt ratio.

Sorry for the delay in answering some questions.

1. Yep, counted wrong. There are 11 pictured. I have my main system in the dining room, for a total of twelve.

2. No, I do not need any type of heating at anytime. I leave my patio sliding glass door open all the time. Sometimes, like now, only open a few inches, but still open. I believe my last electrical bill was $105. But it does go into the $150s when I run the A/C in the summer.

3. Yes, I bought all of these systems used just to build a GIMPS farm. I am a member of the Ars Technica team, presently in 12th place there. I believe I would be in the top 102 if I was on my own.

4. Yes, these machines are on 2 different breakers, both 15 Amp. I am sure I am overloading them. I had to move the farm into the living room from the dining room due to the failure of the 20 Amp breaker there. My landlord was not pleased when the electrician came to replace the breaker and was informed of the reason of it's failure. I was told to remove it, so I removed it from the dining area into the living area.

what you do is put 2 or 3 in each room -_- that way theres minimal load on breaker.

Once there was a power failure in the middle of the night and I woke for no reason. Then I figured out it was too quiet. The pharm was down. I couldn't get back to sleep for quite awhile.

No noise.

This is so called addictive.

I have only 4 machines running Prime95/mprime, and all of them are protected by UPS, so short-time power outages never stop them making noise

Attachment 1074

so thats a pic of the main campus so when you worry about power draw think of the a building with the equivilent of a substation in it.......
-_- its a big place


Moo, speaking of "it's a big place...."

I found a nice site for my new "farm".

It's only about a mile from my house which is convenient.

This building was built recently by LG Electronics as a production and distribution centre but they moved out and its now vacant.

http://www.vigo250.com/location_aerial.htm

Checkout the pics and specs. 250,000 sq ft is a LOT of space.

Particularly useful is....

• 1000 Kva electrical supply with potential for much more

LOL "for MUCH more!"

• 40KN/m2 floor loading

needed to stack PCs up to

• 9.6m apex (5.4m eaves)

ALTERNATIVELY, I found something else. The interior looks a bit like some google headquarters. Actually the previous tenant was a dot com business.

http://www.sandersonweatherall.com/main/propsearch.aspx

Select TOWN as "Newcastle upon Tyne"

In additional search details type "Victoria" short for victoria house.

That will bring up the property using some Javascript form.

Click on the link to the PDF of FULL details.

Sorry their javascript does not supply a no-hassle direct link to the pdf for you.

Very nice place, but then I wondered, would only 10,000 sq ft really be ENOUGH?
