Title: WTS Rig or Parts - 3 5970's, MSI 890FXA Ram, CPU, PSU, extenders
Post by: jjshabadoo on January 08, 2013, 04:09:20 PM
I have a complete rig which includes:

MSI 890FXA-GD70
Seasonic x1250 gold psu
3 x ATI 5970
3 pci x16 extenders
sempron 145
2GB ddr3 1333 ram
hard drive
Windows 7 64bit


The windows key is a single use business key, i.e. if you have to wipe windows you will need your own key to re-install.

As of now it is running at 750mhz engine 150mhz memory at 1.000 volts.

This machine has been running well for 6 months using cgminer. I have cgminer 2.7.4 installed and configured, working fine.

Asking price $1050 shipped.

Offers accepted, through PM please.

Willing to part out also, just thought someone might want the whole thing ready to go.

Make offers via pm.

how warm do the cards get while mining with all three in the case?

they're in a case?

i guess there is no case listed, so no. my mistake

I have them on pci x16 extenders, all three cards run 53 - 61c range across all 6 cores.

315 mh/s per card.

I would happily send the extenders and the white wire rack I use to keep them up and away from the board and each other.

You would just need a motherboard tray to mount the mobo for an open rig.

Updated post, part out or whole rig.

Willing to make a better deal on whole rig.

Everything was received on Monday in working order.  One card's fan was just about shot, but I don't think that was intentional (it still works...  I just notice because I deal with many of them).

Great transaction.  Everything was packed well and jjshabadoo had excellent communication.  Thanks!

bummer, I got here just a few days late.  My 5970 is on the fritz.  It freezes when I try to start up...

Looking for a new used one.  Any chance you can use mine for the fan?

Thanks for the offer...  I keep spare fans around though.

Have you tried starting the 5970 at very low clocks (600-650ish) and waiting for it to heat up?  I've got 3 cards that do this (they need reflowed).  Once they are up to temperature though (60c+), they run flawlessly at higher clocks.

I don't know how to start up at low clocks.  My googling abilities failed me :(  If it's quick, I'd appreciate a could steps.

Is there a way I can edit registry settings, or do I have to go through some USB flash approach? 

I haven't tried that before, but I'm also thinking about selling it to a guy at the moment so I don't want to damage it further than it already is.

this is kidna whats happening to one of my 5970, but one of the cores wont accept any load at all (mining) unless the adjacent core heats it up to about 65-70C, then I can start it at normal clock speeds. It's a crappy card anyways though. Master maxes out at 740Mhz @ 1v, slave maxes at 755 @ 1v. Most of my other 5970 get about 770-800ish.

Of the 7 5970's I've gone through (still have 4), only 2 cores couldn't hit 900Mhz @ 1.125...  740 & 755 are really bad.  =p

I have one I run at 835-825 @ 1.05v, one at 800 (weak core #1)-845 @ 1.05v, another at 820-820 @ 1.05v, and the last at 820-810 (weak core #2) @ 1.05v.  In general, it's about +15Mhz per voltage increase (1.05 to 1.063 to 1.075 to 1.0875 to 1.1), though the 800 one caps out at somewhere between 866-875 (it crashed at 875 twice, haven't bothered going above 865 since then) and the 810 is similar, around 870-880.

The best one can do 950 (140 mem) @ (**ed: 1.150, not 1.250) (unsure past that, the VRMs were around 100 and I wasn't very keen on going any higher on the voltage anyway... the card never went above 70oC though, since ambient was around 25oF..).

I don't mess with them much anymore, pretty much gave up on the hassle of the testing, so they run at something below 1.05 when it's going to be > 70o outside, 1.05 @ <70o, 1.063 @ <60o, 1.075 @ <50o, etc.  
I've had a few issues.... (like when the forecast is 55 and it's 68 or something)  They could use a nice cleaning but I'll just wait another month or two for that, I guess.

I don't overvolt. I undervolt. Some of us actually have to pay for their electricity.

I pay 6.9c for my electricity..  in general (except for a while after the halving), it's been more profitable to overclock

i would have already sold my stuff off if my elec was >10c (which would have been unfortunate for the last month or so)

ed: oh, as an aside, i suspect I must have read the 1v and somehow got the 1.05v perf 3 base voltage from it.  during the summer i ran my 5970's at 0.99v, ~760, due to the heat, not from it being more profitable
