5 rigs on one strip does sound like quite a bit(especially for a single outlet since older houses are usually only built with 15amp breakers and outlets) however a 20 amp power strip like this one is what i used when i built a "mini rack" to run all of my rigs in one place(granted i only had 4)

It looks good, a little more polish and you'll have something that most people can use.

bingo on the presence pins, also no one should be buying dummy plugs at this point they're always overpriced retaliative to their function(and usually not needed due to the latest drivers)

it's up to your HSF design, sometimes that shell acts like a duct forcing air to move through the metal fins of the heatsink other designs it's  purely cosmetic, your particular card looks like you might not notice any difference shroud or not.

Try starting the Command Prompt as an Administrator.

Always do... and.. I'm logged in on the hidden Admin acct. Smiley

you have to explicitly launch the command prompt as an administrator even if you're on an admin account(right click run as administrator) otherwise it won't have admin level priveledges

It will.. or supposed to. Like I said, I run EVERYTHING as Admin even though I may be using the Admin account.

It happened again today, but this time there was no web browser running so now the main suspect is... BTCmine ! lol

I'll run it by Dbitcoin once more.


even if you're on an admin account not all programs launch with admin level permissions, the commandline is something you have to actually tell it to launch with them (right click run as administrator)

This kind of thing should have been on the forum a long long time ago even late would be better than not at all.

the delay from the pass through could cause issues but i can't imagine it would be any kind of bandwidth issue just added latency and the potential for driver problems. without testing i couldn't tell you anything for sure.

lol at how bad milk crate rigs are  ( i have 20 rigs of 4 7950s and have tryed nearly every difrent rig setup out there lol ) thats why it was anoying people sed my rig was the worst ever

question for you.

I have 2 system each with 4x 7950.  I am running into an issue when trying to bring the 4th online.  CGMiner says its SICK then DEAD and reports the temp as 511 degrees

I have a corsair 1200watt PSU and I think I have narrowed it down to this.  The card that dies is the one that I have to use 4 pin Molex to 6-8pin PCI-E power.  What do you use for your setup?

thanks!

A refrence 7950 pulls 250-300 watts when used in a gpgpu scenario
That puts the draw for 4 of them at the full capacity of your psu and it's unlikely that your entire 1200 watts is available via 12v power.
you're going to need to investigate dual psu options, larger psu's or limit yourself to 3x 7950 using that particular psu.

it looks like the old bfl single(same size general shape) but with different venting
51  Bitcoin / Bitcoin Technical Support / Re: Event ID 1/ system time change causes gpus to stop mining. on: June 03, 2013, 03:10:45 PM
do that and go into the command line and try this
Code:
net stop w32time 
w32tm /unregister


that should forcibly disable the windows time service(and eliminate your recyncs
to re enable it you'll need to do
Code:
w32tm /register 
net start w32time
w32tm /resync

is windows update enabled by any chance? i know it can change the time when it checks/downloads updates

@zackclark70

Exactly what I wanted to hear for my 7950 he he

@deslok

That is the nature of my dilemma. There are boards which have issues with more than one. Hmm... need to obtain powered riser then, or two, even better whole 3 or 4. Just to be sure  Cheesy

no need to power every riser just the last one in the chain

That does not solve that the first part is only using the usb as a data transfer from an existing pci-e port not actually a usb>pcie adapter

looks a lot like alibaba(where i have ordered some things from) caution is the key word(some good things some 2gb=64gb flash drives)

why not make the field alphanumeric then at allow it to be risked value, let people denominate it in whatever they want.

Because the numeric value is used in the trust score calculation, so there needs to be a consistent measure of value.

So people can overvalue their transactions by bartering a lot of high value paperclips(you can get houses for those still right?

On a similar note I have a question. How many x16 extenders I can use without problems with power supplied via PCI-Ex slot? I want to move mining VGAs below motherboard (Mountain Mod case with horizontal tray), away from hot RAID controller. I'm currently at the stage of thinking the mounting system (slightly more sturdy than zip-ties  Wink) for cards right next to 2 exhaust fans which are bored blowing out cold air. I want to 'employ' them in, let's say, more productive manner.  Grin

One extender is ~15 cm long. Thinking that 4-5 will do the trick without the need to overstretch cables (+ possibly right x16 riser at the end). My only worry is potential drop in power supplied with each extender added to the line.

I can't say i'd reccomend that many without the last one being a powered riser(every inch is more resistance) but i don't know of any spec that would discourage it offically
59  Other / Meta / Re: Marketplace trust on: May 31, 2013, 03:22:41 PM
Edit:
Imo, that would be a form of lieing.

No, because the "Risked BTC" field is only meant to indicate how much value you risked. It doesn't matter what currency you used. You could even use that field for a barter transaction where no BTC was involved.

why not make the field alphanumeric then at allow it to be risked value, let people denominate it in whatever they want.

I don't see any room for driver or bus issues there at all >.>
one is these is going to be more practical if you can find it for sale somewhere

Too bad this was not available 2 years ago.
