i5-2500k Won't Overclock?

post #1 of 20
Thread Starter 
I just got my new PC parts in today and finished putting the machine together a few hours ago. It runs like a beast at stock speeds, but obviously bought the i5-2500k to overclock.

I picked up this motherboard (Biostar TH67B)
http://www.newegg.com/Product/Produc...82E16813138308

I watched a Youtube video of someone overclocking to 5Ghz so I could find what settings I needed to enable/disable. Lastly, I just changed my ratio from "33" to "34" to test it out as a 3.4Ghz OC.

I saved, restarted, and checked in CPU-Z and SpeedTest and it didn't change. Still had it listed as 3.3Ghz. I also noticed that even with Intel SpeedStep disabled, my Core Speed is showing in CPU-Z as 1596.5Mhz w/ Multiplier 16x.

Does anyone have a clue what the issue is?

I might be a prick for asking, but did you save bios to cmos?

The motherboard you chose is not compatible with overclocking, you must have a p67 or z68 motherboard to overclock with those CPU's see if you can return your motherboard and swap it out with one of those chipsets I mentioned. Otherwise you're kinda stuck :S sorry

should have gone P67...there's a bit of ambiguity on how an H67 can overclock, even on K-cpus. Limited at best.

That's an H67 board which IIRC you can only overclock by modifying the base clock frequency, not by changing the multiplier. You'll only be able to get a few hundred Mhz at most I fear.

Yeah you cannot OC on a H67 motherboard due to the fact that there is very limited BCLOCK overclocking on 1155 and you cannot increase the multiplier with H67. You need to get a P67 or Z68 board.

Ouch, I did not know that. It came with Overclocking Software and the BIOS seems to be pretty optimal for Overclocking. Why can't it overclock?

Sounds like you still have some Power Management Features enabled in the Bios.

But like others said, not the best board for overclocking such a chip with, P67 would be what you needed.

I guess intel locks you out.

They are starting to do strange things with Overclocking.

Locking out chips, and now chipsets.
