donholio Posted December 6, 2010 Share Posted December 6, 2010 I picked up a Intel i7-950, Gigabyte GA-X58-USB3 Motherboard, and a CMX6GX3MA1600C9 kit on Black Friday and I have been having significant issues with stability ever since. I have a 550W CoolerMaster RealPower Pro Power Supply that I have had no issues with powering my Core2Duo system before upgrading the Motherboard, CPU, and RAM. I checked the Extreme Power Supply Calculator which told me I should have a minimum 430W, recommended 480W power supply. I backed up my data and reloaded Windows 7 x64 on the hard drive as soon as I could. I began having blue-screen issues almost immediately. What's strange is that I rarely had issues at load. Sometimes I would get a blue screen when I was performing multiple tasks (copying data from one drive over the network and opening a browser window, etc.). Most of the blue screens seemed to happen when the machine goes into a power-saving mode. I have reloaded the OS at least 2 times since the first reload (3 total) in the past week. I have been browsing forum posts and trying different voltages for the QPI/Vtt and DRAM voltages. The motherboard recognizes the X.M.P. Profile and gives me 1.65V for the DDR Voltage but only 1.2V for the QPI voltage. I raised that in the voltage settings window to 1.36V. There is also a DRAM Voltage setting there that is defaulted to 1.5V. I tried to leave that as default, but have since pushed that to 1.66V per discussions on this board. I have even tried to run the RAM at 1066 at the same voltage setting the CAS latency to 9 and CMD rate to 2 manually. None of this seems to help with the stability. So I did what I have in the past - MEMTest. It comes back clear with no issues even after 6 hours so I don't think it's the memory, but rather a settings issue. When I run OCCT and it brings all the cores to full power, I see 74C-78C heat. Nothing over 80 ever. I am wondering if I need to go higher to combat the memory going into a lower-used state and possibly lowering the memory voltage. I am really struggling here to try and find that right combination, but I don't want to go too high on voltages and ruin the CPU, Memory, or Motherboard. Here's the CPU-Z Validation page in case that helps. http://valid.canardpc.com/show_oc.php?id=1520678 Thanks in advance Link to comment Share on other sites More sharing options...
