yes i know. But i can't go above 7k ATM. Yes may be i have to forget abt oc but i am ready to accept this.
You need to increase your budget to get good motherboard. It is not a component that you can opt for a cheap one, or same thing will happens as what is happening now.. problem after problem.
@7K you don'r get anything better than cheapo boards from Asrock or Biostar or even DFI.
Talking about gigabyte, GA-Z77P-D3 @9.5K is the minimum choice for you.
Or, G1 Sniper @11.3K would be the best choice IMO.
Intel Z68/Z77 board?? Avoid it!!!
P.S.
This is why I don't like Biostar. Pathetic serice coupled with low quality. Nice to see that at least one person is getting the scope to feel the reality.
Sell your old biostar tz68k n add that money odawise get gigabyte b75 or h77 mobo undr 7k
B75 or H77 isn't an option for 2500K due to inferior power phase design. If overclocking is done by mistake using software, nobody knows what will happen to the board.
