Hey everyone
Been running this setup for a while now and I was stable at 4.2GHz for about a year, the other week I simply put in a manual vcore of 1.3v and changed the core ratio to 44 per core and the machine had a massive tantrum, wouldn't post, no display, clearing cmos did nothing, switching mobo bios did nothing - I stripped it all down, removed the cmos battery and powered it up with 1 ram stick and 1 GPU, rinsed and repeated until I had 3 ram sticks (4x4GB DDR4 2133) but every time I installed the 4th stick it would not post again, even if I mixed the sticks around.
I defaulted back to 1 ram stick and installed the second GPU (SLI 970's) and I got the same issue as before, if I swapped the secondary GPU for the primary GPU it would not boot - so two GPU's would not boot and using the secondary GPU in place of the primary also would not boot, but if I used the secondary GPU in a friends PC it booted fine.
I sent it all off to Scan in the UK, they tested it all (CPU, mobo and RAM) and found no issues at all, sent it back to me and I rebuilt it and it powered up straight away..... weird. I've used the machine now for about a week and it has been totally stable although now one of the temp sensors on the mobo is reading 127c all of the time (HWMonitor) and my core frequencies seem to be acting very strange..... It will idle at 1200MHz but even under no load it is boosting to 4GHz randomly from core to core, EIST is enabled, turbo is enabled, power plan is on balanced and my core ratio is set to 40x100 - can anybody think of why the frequency isn't jumping up or down in 200mhz increments or whatever it is? Even opening something like Chrome sends all cores straight to 4GHz, this never happened before.
Oh and XMP is not enabled, c states are enabled.
