Sundownz; thanks for the backoffice explanation.  I travel a lot and have a need to manage my rigs remotely.  I do most of my stuff over RDP. I have already setup my boxes to auto boot and auto login.  This is what I use to get Win 7 Pro to auto login:

HKLM\Software\Microsoft\Windows NT\CurrentVersion\winlogon
AutoAdminLogon = 1 (String Value Key) (0 means off, 1 means automatic)
DefaultUserName = YourUsername (String Value Key)
DefaultPassword = YourPassword (String Value Key)
DefaultDomainName = YourDomain (String Value Key)

Hopefully this nugget helps someone else. Took me a bit of googling to figure it out.

Sundownz,

Admiring your setup!  Can you advise on what you run on these systems?  What OS? Are you on a network with a domain controller, or just workgrouping them together? Are you running any anti-virus on them?  What apps are you using to mine and manage your rigs?

-Good to know your build can withstand the NC heat; I am in Richmond, VA, so pretty much in the same boat.

Thanks for the ideas!

Paul

Just found a source for T7500's @ $125...  I see a single mention someone earlier in the thread; just wondering has anyone had success turning a T7500 into a mining rig?  They seem to be close to the T5500 in design...

$125 ?! I can't find them for any cheaper than 275+ EUR Sad so that's a steal! Especially considering this ...

Dell T5500 is the equivalent of a HP Z400-series
Dell T3500 is the equivalent of a HP Z600-series
Dell T7500 is the equivalent of a HP Z800-series

... and T7500 seems to come with 1100W PSU by default. And with two PCie 16 slots with upto 225W (instead of 150W of HP Z400) out of a total of the similar 4x PCie according to http://www.dell.com/content/products/productdetails.aspx/workstation-precision-t7500 . It sure has great perspective.


I just bought the last two T7500's for $100 a piece.  Starting my build soon...

Hello all,

Stoked to see that I can actually do something with an old T5500 that was about to be tossed into the dumpster at work...  It came with a 1GB Nvidia Quadro 600 card and 12 Gb Hynix Ram.
A quick search brought me here and since I had been planning to build a miner I struck gold it seems...

First problem is that the system won't boot up.  I got a blank HD in it, but I have the dreaded "2-3-4 blink with solid amber power light Pb7" code. Tried the usual and I am now looking at replacing the X5650 CPU.  If that works I am planning to add a few 580's and fire it up.

Love to hear if someone else has had to work through this particular issue before and has insights.  I'll post my build notes along the way...

 


Update: swapped in a new X5660, still getting the same error.  Looking for a new CRH6C motherboard now...  Maybe it makes more sense to get a HPZ400 as it is close to the price of a replacement motherboard.  Hm.
