Re:EVGA X79 Motherboards - BIOS 037 Released

mwparrish tennis_ski I don't know if this will help you, but here goes... On my X79, I have the G.Skill 4x4GB DDR3 2133Mhz RAM also (mine is the 11-11-11-30, tho). I have been able to run it with manual memory settings, but doing that seemed to cause issues with the USB 3.0 controllers, and I was also getting infrequent blue-screens (IRQL_NOT_LESS_OR_EQUAL, CACHE_MANAGER) that pointed to driver issues. So, this past weekend, I upgraded the ASMedia USB 3.0 drivers from the 1.6.3.0 to the 1.14.8.0 level (with much trepidation, mind you!!), and since I did that, I've eliminated the blue-screens, and all my USB 3.0 ports work fine with either USB 2.0 or USB 3.0 devices. (See this thread for the driver info) Another thing that I did this past weekend -- on the G.Skill forum, there was a thread that mentioned that the VCCIO needed to be bumped up a little when using 4 sticks of RAM (here's the thread where I found this info). Basically, it was suggested to take the VCCIO setting from 1.05v to 1.1v. Well, I changed that setting from AUTO to manual, and I bumped it up to 1.08v to start with, and I as I mentioned, I haven't seen any of the blue-screen issues. I'm guessing here, but I think the VCCIO fixed the blue-screens I was getting, and the new ASMedia 1.14.8.0 driver fixed the USB issues...of course, I'll believe it after everything's been running well for a few more days (week, maybe?), but maybe this'll be the golden ticket! Thanks, but in the previous months we've noted and tested all of this in various different threads before this one. My VCCIO has been as high as 1.250 and my VCCSA has been at 1.250v as well. I have no problem running my memory at 2133 at rated timings at 1.60v - WHEN SET MANUALLY - XMP2 results in NO POST at all times. The issue is always that when memory configuration isn't set to automatic, the USB is flakey - ALWAYS. Before my RMA, I updated the VLI USB 3.0 hub firmware -- no change in reliability; upgraded the ASMedia USB 3.0 controller firmware and drivers -- no change in reliability. It's linked to something with memory management/configuration. When something is changed, USB 3.0 becomes unstable. Here some threads previous to the one you linked to: http://www.evga.com/forums/tm.aspx?m=1575691 http://www.evga.com/forums/fb.ashx?m=1560665 http://www.evga.com/forums/fb.ashx?m=1561462 There are many more... but it would be useless to keep linking at this point... In some of these threads, Jacob mentions that they cannot reproduce the issue in house. Support said my RMA'd board tested fine... so either it wasn't tested with the memory I specified or with the settings I specified to reproduce it. But since it's reproducible for me in an X79 SLI and two X79 FTWs, my memory is stable and tests OK at any frequency between 1600-2133, and I swapped a 3930K C1 for a C2 and it's all the same... USB 3.0 refuses to work right except when memory is set to automatic. As it also does on my X79 Classified! I've updated every driver I can..., and the USB 3.0 ports are still flakey! $450 for a motherboard, and I had to buy an expansion USB 2.0 hub to plug into one of the USB 2.0 ports on the back so that I can run everything without having to have cables plugged into the front USB ports on my case!
