[/quote]Well that was a certainly an interesting read, the more you know. :)
A little curious as to why 80 shaders are locked down initially, it’s not like the sold this cards at a cheaper price. Hmm. -
Current setup
None are headless atm though.
Running cudaminer and cgminer atm.Machine 1
[b]GTX 560 SE[/b] - 61 KHash/s @ 830 clock [i](get around 90 stable without anything else messing about (could probably get 110KHash/s headless))[/i]
[b]HD 5850[/b] - 206 KHash/s @ 725 clock [i](get 300KHash/s headless)[/i]Machine 2
[b]HD 5750[/b] - 108 KHash/s @ 900 clock -

Im only running 1x HD5850 @ 310 KH/s 8)
[/quote]Same… I get about 380-390 if I set I18 but then I can’t use the machine. With cpu mining included I get about 410.
depressing when you see pics of people who’ve just bought things specifically for mining. oO

It is a little, especially when I think ‘why can’t I afford to do that’ xD
That aside, I’ve just used my gaming rigs, not brought any hardware specific for mining really. (If I was, I’d of brought 3 x 7950s instead of 2 x 7970s =w= ) -
See below :)

I repurposed a few old computers, shockingly getting even 60khash out of some older cpus.Main effort is my aging 5770 that runs at about 190Khash when I go to itensity 18.
[/quote]Sheesh how are you getting 60kash out of old CPUs? :) what software are you using?
[/quote]
I use minerd (pooler/cpuminer from github) on them under Ubuntu. Some old dual core cpus can even score strangely high, probably because they have a higher rate which these days get’s compensated with more cores (and lower clock speed). I run on an old toshiba Notebook, that’s at least 6 years old now with 26K hash even.These are speeds I read on the accepted messages from minerd, so they are the real ones, not some odd ones some pool s sometimes report on.

4X 7950 running an average at 2.4Mhash in total, no overclocking done.

Good grief, that threat and setup of Detritus’ makes me flail and want to do it o-o; -
I’m hardly a hardcore miner, but my 7850 is pushing along at ~302kh/s.
I’ve had it up significantly higher, but am pretty satisfied considering I’m only working at intensity 13.It means I can do other things on my rig… like read this pretty forum :)

7850 @ 365 KH/s

Hi DeadZebra,
I’m getting about the same hashrate as you averaging about 610 per card.
I have 4 7950s on my board (3 cards in the pci16 slots and 1 in a pci1 slot) and for my next project I’m going to try to mount 6 7950’s to a board, I haven’t looked for a board that can take that or even if its worth doing because I heard you can fry your pci slots with too many cards, so my question to you personalty as you use the 7950, is would you limit your rig to 4 cards or try 6? -

[/quote]I’m not sure about 6 but I think 5 might be fine because I have heard of many rigs using a 5 card setup but none using 6x 7950. You are going to need to use PCI-E risers for a 5card setup though I think.

[/quote]I have the 4X 7950 setup on risers which is great for cooling, but I guess its a 5 card setup for the next rig, it must be a motherboard limit. Cheers for that.

I just ordered a 7 slot board and will try a 7x7950 rig :) I even found a supplier that sells PCIEx1 to 4 * PCIEx1 for about 180 a piece. If that works I might be able to do even more. Though the drivers only go until 8 I think.
-
Damn, feel bad. Mining for 9h straight and found 188 shares -.-’ ahh my GPU sucks…

[/quote]Cool man let me know if it works :) would be very interesting to hear about.

[/quote]Indeed! Are you making your own case? You should make a topic and take some pictures!
-
I’m making my own “case”, yes. I’ll weld steel together for it since I got easy access to it. I’ll start with a simply open frame and then see if adding sidepanels will improve airflow and temperatures. Working on a simple 3D model for it now so I got all the measurements right. I’ll make a thread and post pictures as soon as there is something to see. Apparently ordering 7 GPU’s at once is uncommon for my purchasing place of choice and so I’m still waiting on those. the rest would be ready.
