I bought the following setup from OCUK this week and im having nightmares with freezing

Gigabyte Z68AP-D3 (MB-364-GI)
8GB Kingston HyperX DDR3 (MY-094-KS)
Intel Core i5 3450S (CP-416-IN)
Crucial 128GB 6Gb/s Solid State Hard Drive (HD-009-CR)

after setup of the board it didnt post so i returned it to the OCUK counter and the tech guys flashed the BIOS to accept my cpu.

Upon returning home all went well, i left setting in bios and everything run great during windows 7 install.

Then after a few setups and installs i notice it starting to crash and randomly freeze.

so i decided to download and boot memtest86 first, ran that with zero errors.

i then decided to re-install OS from fresh format on the SSD, still freezes i then proceeded to check GPU and swapped to a working GTX 560Ti still locks up.

removed everything non essential and still locks up. Went down to 1 stick of RAM (4GB) still same effects.

i also notice the CPU temps are around 31'c and everything seems cool temp wise.

any suggestions before i start thinking about possibly returning this for ocuk to check? its completely random and even locks up in the bios once or twice.

this is all also running on an OCz 650w PSU in antect case with nothing else.

Thanks for any help guys.

did i buy a crappy mobo that wasnt designed for the CPU etc?? its a rev 1.0

or can someone recommend a decent board to go with this cpu / memory combo?

I have same mobo as you, and it is not crappy it has 2500+ reviews which give it 4.5/5.

However, if I was building my PC recently I would go for newer

I think Stulid mentioned it in other thread and I argued that it was more expensive, but I was looking at other motherboard, so if you are looking to replace Z68 that mobo would be good replacement in my opinion.

unfortunately i don't have anything that i can use the HDMI port on =(

im currently on latest release bios by gigabyte for the board "F8"
Click to expand...

Set the BCLK to 100.1Mhz
Set Windows power options from balanced to High power

That beta BIOS is UA4, it allows overclocking of Ivybridge chips.
 
Those boards are early z68,they don't have onboard hdmi or dvi ports which is rather silly,try with only one ram stick installed,ill post latest beta BIOS when I get time,on phone atm,also press n hold alt and f12 at splash screen to flash both back up and main BIOS chips with the same BIOS version,that can cause freezing if they are mismatched

It does have HDMI output.:p

Stulid,RJC got there first :/
 
thanks for help so far guys im trying each suggestion as we speak.

am i right in thinking:
Intel's new IvyBridge based CPU's is a refresh that requires socket LGA1155 mainboards based on Intel Z77 Chipset. (From CPU desc)

means i should actually be on a "Z77" board???

You could use older Z68 but Z77 would be better choice... + nearly no price difference

The CPU is fine in any board that supports it (H61/H67/P67 etc etc)
 
another quick question as well:

right click of my computer gives me the following:

Intel(R) Core(TM) i5-3450S CPU @ 2.80GHz 3.40GHz

whats the 3.40GHz mean? i can only assume it can be clocked to that?
