SB-E 3820 Hangs/Lags Screens Provided

[gonnabadoc]

I just recently got a i7-3820 LGA2011 setup with a Asus Sabertooth X79 Mobo.

On both a fresh windows install (SSD) and two old Win7 installs (HDDs) the computer is hanging (programs stop responding 5-6 seconds) during basic tasks such as minimizing a window or changing tabs, or just sitting here typing. Sometimes just one program just stops responding and other times all programs freeze for a while.

The Resource monitor says that the CPU total frequency is hitting 100% whenever the lag occurs, but I don't know why or how to fix it.

Any help? Thank You.

Update: I changed the bios profile to not throttle cpu frequency so that processor is always running at 100% frequency.

The lockups now correlate to the CPU frequency dropping to 0%...

Anyone have any idea how I can figure out whats going on?

Solved...

In order to stop the crashes using Gskill 8x4gb 1.5V 1600mhz ram I needed to enable the XMP profile in the bios for the Asus Sabertooth X79 mobo.

16gb system memory worked fine with 11-11-11-28 timing but needs 9-9-9-24 for 23Gb

I had similar issues with my X79 MB and SSD. First of all check your SSD firmware version. It was up to date but vendor listed a lot of similar problems for versions below. After a few days playing with hardware I figured out that problem was in a single SATA cable to one of used HDDs in my box. Yes, one single SATA can produce lag in LAN and other HDD/SDD devices. I guess it's because everything is packed into a single chip and it interrupts all those subsystems.
