I recently purchased (new) a mobo/cpu/RAM (in my system specs) and have already had it repaired, as it refused to run my 2133MHz RAM over 1600MHz and even then it had to be single-channel. Got it back yesterday and found the following: - RAM runs properly now, but mouse still jumps around in the BIOS, making any setting changes extremely difficult - running the CPU at any speed other than AUTO causes the system to fail (OCing is out of the question) - All components, other than the mobo itself, work 100% reliably in a different system (so it's not a RAM/CPU issue) - updated the BIOS to the latest version, just in case there was some kind of compatibility issue Now, the system does run reliably, as long as it's not pushed in any way (ie OCing), but that seems a bit silly, when the system it replaces is my old 965BE and it's no faster than that old system was. Could there be some kind of setting I have missed, or is this mobo just fubar? Any insight is most appreciated EDIT: would you believe this mobo is NOT compatible with wireless Microsoft keyboards - this causes all the aforementioned issues. Now running Logitech and zero issues!
