I got my Sabertooth Z77 a week ago, since my old P8P67 has passed away.
I'm still having my Core i7 2600k and G.Skill F3-12800CL9D-8GBSR2
At first, after building the system, I turner on the comp and everything seemed to be fine so I started to install all drivers for the new mobo.
After a few reboots needed by driver installation, the computer started to randomly freeze.
I decided to run prime95 to test system stability and I got an instant freeze and after turning off and on again, the system won't post anymore, having the cpu red led on.
I thought the cpu was damaged so I got a G530 and after installing it I started to get dram red led and I had to move the 2 dimms to B1 and B2, no other combination would let the computer post.
Today I updated the bios with the 1403 version and for my surprise, dualchannel is working perfectly now, so I decided to give it a second try to my 2600k with the new bios and the computer posted! and I made it to the windows desktop, but only for 10 minutes till it got freeze and never posted again having the red cpu led on.
Btw, my 2600k was tested in a different mobo and it's working.
Could it be that 2600k + SB z77 + F3-12800CL9D-8GBSR2 is a bad combination?
Any help is welcomed and sorry for my bad english + the text wall
Alright, I'm back with news:
It turned out that the problem was the processor (the P8P67 carried the 2600k with it...), and yesterday I got a new one through rma.
However, the problem with the dual channel not working was only fixed after a bios update with the 1403 version.
Now everything is working like a charm, except for this:
There is no way I can make the IGP to work after installing the intel drivers.
If I set IGP as main graphics, I can see tuf logo and the windows logo, then the screen turns off but the computer is still working.
If I uninstall IGP drivers, then I can get into windows without problems, but after installing drivers and restarting the computer, all I get is black screen.
Anyone having similar problems?
