Good morning, gentlemen. I have decided that now is the time to part ways with my desktop system. I can no longer deny the fact that it is overkill for the tasks I put to it, and so I am selling it on. Based on the x79 platform, the system can accommodate up to 64GB and Quad-SLI for an entirely beastly setup. I doubt there is going to be much interest here, given the nature of this beast, but I figure it was worth at least offering it to you. Before I list the full specification, I have to make a confession. It seems that there may be a problem with the CPU, albeit a minor one. The system requires a large increase in vcore in order to get it to run in a stable fashion with all of the memory sockets populated. With all eight populated, I had to push the vcore to 1.4v. With six populated, it still required 1.35v (which is within Intel's specification for the CPU). With four populated, everything works normally; even at 100% load in OCCT the vcore doesn't stray above 1.25v, and all the cores turbo up to 3.6GHz as expected. I suspect it's because the memory is from different batches with different timings, and the x79 platform is extremely fussy when it comes to memory. With a full set of matched memory the problem may be resolved - I don't have the resources at the moment to test this theory. As such, the system will be sold with 16GB in order to allow me to sell it as stable. With that out of the way, here is the specification; Intel Core i7-3960x Asus P9X79 PRO Intel X79 (Socket 2011) DDR3 Motherboard Gigabyte WindForce GTX 670 2GB Corsair Carbide 500R Midi Tower Case - Black (CC-9011012-WW) Corsair Vengeance Arctic White 8GB (2x4GB) DDR3 PC3-12800C9 1600MHz Dual Channel Kit (CML8GX3M2A1600C9W) x 2 (total of 16GB RAM) Noctua NH-D14-2011 Dual Radiator CPU Cooler with PWM Fans Crucial M4 256GB 1TB SATA drives x 2 Creative Sound Blaster X-Fi Titanium DVD-RW drive 3.5" bay fan controller Hiper Type-M 780w PSU I have the boxes for the memory, processor, motherboard and graphics card, which you may have. The PSU is about 5 years old and so is out of warranty, otherwise I am pretty sure everything else is in warranty. Collection from Croydon is the only way I can sell this, as it's just too much of a risk to ship it. In light of the issue with the memory/CPU I am asking only £1000 - to build the system from scratch would cost over £1800, so I think my asking price is quite reasonable. If you have any questions, please do not hesitate to ask!
