1  Economy / Goods / Any Interest in a 1.1 GHash Miner/Gamer Rig for $1100? SOLD! on: July 22, 2011, 03:40:17 PM
I built a miner and it took a while to get up and running.  Finally I got it going strong at 1100 MHash/sec.  I run it non-stop and have no problems.  It could be pushed further with more tweaking on your end.  Temperatures hover around 55 on 1 5850, 60 on the other, and 65 on the 5870.

Specs:
WD 250GB Sata 6 GB/s 7200 RPM
G.Skill Ripjaws 8GB PC3-10666
AMD Phenom II X4 955 Black Edition
2x XFX HD5850's  - 355 MHash/sec each
Sapphire HD5870 2GB -  400 MHash/sec
Azza Helios 910 Case
MSI 890 FXA-GD70
COOLMAX| ZP-1000B 1000W PSU

I am paypal verified and will only accept payment via paypal, no BTC.  

I have earned quite a few BTC using this rig but its not as profitable as I'd hoped for, and yes I was a noob thinking old money factors would last longer than 10 days.  Looking for $1100 via paypal.



THE RIG HAS SOLD.

To all:

I've been working on my new rig for over a week, literally.  Stats as follows:

Phenom X4 955 black edition
Asus Crosshair Formula IV
2 x 4 GB G skill DDR3 1600
2 x XFX 5850 1GB
1 x Sapphire 5870 2GB
250GB seagate 7200 RPM sata 6 GB/s
Dynamax 850 watt PSU
NZXT zero cool (I'm changing to an Azza case tonight)

For two weeks I had a coolmaster 750 watt power supply and only ran the 5850's.  I easily overclocked to 895 core and 300 memory getting 335-340 Mhash consistantly with temps around 65 C.

This past week I added the 5870 and immediately had issues.  From every review of tripple crossfire on 5870's the most I saw in power use was 600 watts, so I thought 750 would be fine.  Yet even still my PC would shut off within minutes of trying to mine on all 3 without overclocking. 

So I upgraded to the 850 watt PSU.  I can mine on all 3 for at 870 core on all 3 cards.  Temps are 55 on the 5870, then 85 and 65 on the 5850's.  The Azza case will give MUCH better airflow so hopefully temps will get under control.

MY PROBLEM:

When I clock the 5870 to 900 core and 350 mem, along with just one of the 5850's mining at 880 core 350 mem the computer shuts off like the PSU is insufficient.  If I clock the mem down to 300 I can't even start mining as the computer freezes.

ANY HELP?  I use afterburner and trixx FYI.
