i5 6400 oc - Can they all oc?

[dimster]

I am interested to buy a i5 6400 and oc it!

I found some used ones on ebay and I am tempted to buy one of these babies.

My question is are all of them capable of oc?

I know that the motherboard and the bios version are important so considering that you have an ideally capable mobo, would also any i5 6400 have a 100% overclock ability?

Only the 6600K and 6700K can be overclocked using the core clock multiplier, and this is the recommended way of doing it. Technically any Skylake processor can be overclocked with base clock (BCLK) adjustments but this requires a Z170 motherboard with a BIOS version that has not been patched to prevent BCLK overclocking of non-K processors. And BCLK overclocking is not quite as easy and stable.

In short if you want to overclock, buy a 6600K and a Z170 chipset board. Also, I would recommend against buying new PC parts from ebay.
