When looking at the dates set in the poll please note that the system has been running since the 12th October (4 weeks already) with the RAM @ 1.65 V, with regular gaming use, some video encoding and some benching. A fun experiment! For my new build I decided to try my luck with Skylake and my existing Corsair DDR3-2666 RAM that runs at 1.65 V when using the XMP Profile. I selected the Gigabyte GA-Z170-HD3 DDR3 motherboard for its features and also because the Corsair RAM is on the QVL. I intend to keep this system for at least the next 3 years so if you select the fourth option in the poll I can hopefully still report in on this thread and keep it updated. As of BIOS F5a the motherboard detects the RAM correctly and runs stable at XMP timings as shown in the screen shot; I am getting decent bandwidth with this combination, here is a screenshot of my Ivybridge system running the same RAM with one minor difference (1T command rate); The Ivygridge system has been running with 1.65 V on the memory since I bought it in June 2012, so it's been running for 3 years and 4 months at that voltage without issue. The question is - can Skylake do the same? Place your bets! If you also want to guess at a specific date go ahead - if it does die we can see who got the closest. The CPU is currently overclocked to 4.3 GHz across all 4 cores at stock voltage. I am using a Corsair H80i GT Cooler on Performance mode and the 6700k has not been de-lidded.
