Title: SOLD: 690 Mhash/s mining rig - Brand new - Windows 7 pre-installed Post by: HarryStamperOil on May 24, 2011, 08:07:46 PM Hi everyone,
I'm new to the forum but not to Bitcoin. I recently expanded my mining capabilities and decided that I'd bought one too many machines, so I'm putting this one up for sale. This machine is more or less new. I built it on Saturday (5/21) and started it mining the next day. HARDWARE ASRock 890 GX Extreme 4 AM3 w/ 3 PCI-E 2.0 slots HIS Radeon HD 6950 1GB 840 default core clock, 1408 stream processors X 2 KINGWIN 730 watt PSU AMD Athlon X2 245 2.9 Ghz AM3 processor 2 GB Crucial DDR3 1067 memory 160 GB Western Digital 7000 RPM SATA HDD Basic ATX case w/ 2 extra case fans SOFTWARE Windows 7 Ultimate 64 bit Catalyst Control Center 11.5 ATI driver 8.85 SDK 2.4.595 GUIMiner/poclbm The cards are overclocked to 900 and 880 core clock with Catalyst Control's built-in tuner. The temperature of the cards stays in the high 60s or low 70s during the day, and goes down at night. The room they are in is infrequently air conditioned, so they could be kept much cooler if you choose. Right now I am running caseless, but I will include the case if you'd like to use it. With GUIMiner/poclbm, I use the following flags: -v -f30 -w128. The hash rate fluctuates a little, but gives a steady average of 690 Mhash/s, at times breaking 700. They are not Crossfire'd anymore because I didn't notice a difference between hash rates, and because I moved the 2nd card to PCI-E slot 3 for better airflow and the included cable didn't reach. I use a DVI>VGA dummy so that it registers both cards without Crossfire. You could probably stick a third card in slot 2, but you'd need to add fans or have some other cooling solution. I'll include 2 regular Crossfire cables, as well as the 2x 4pin>6pin power converters. I will also include the retail packaging of the video cards, PSU, and motherboard if desired. The other components were bought OEM. I'm asking 125 BTC + shipping, which you can see from the invoice included below is more or less at cost. The invoice does not include the heatsink for the CPU, which I purchased separately. A comparable rig (http://www.bitcoinrigs.com/products/Enthusiast-Rig-2000.html) from Bitcoinrigs.com costs $1400. I've included the pertinent details (I think). I know that I am new here, so I'll be willing to provide more info or use an intermediary to show good faith in the sale. https://i.imgur.com/tTrRs.jpg https://i.imgur.com/jaPtz.png https://i.imgur.com/8YxSW.pnghttps://i.imgur.com/fK6qm.png Title: Re: 690 Mhash/s mining rig - Brand new - Windows 7 pre-installed Post by: BoomGoesTheDynamite on May 24, 2011, 09:14:49 PM Sending you a pm.
