Hopefully hibernate isn't a problem. That would suck. I've had problems with brand name motherboards and sleep as well. Is there an improved BIOS for this motherboard?E5-26xx Xeons are generally locked so the best you can do for overclocking is maybe tweak BCLK. For overclocking you either want an E5-16xx (or a 2011-3 motherboard with an E5 V3). More information can be found here: Xeon-e5450.ru - Серверные процессоры для игровых и рабочих ПК.

Sleep/Hibernate has always been problematic on the cheapies - but if you look on here even the bigger names like Supermicro and Gigabyte have had problems with it on occasion - although usually with dual boards.
