overclocking on H87 and H81?

[almoststew1990]

I'm planning an ITX build and seen to recall a firmware update or something that enabled overclocking on most of the non Z87 chipset motherboards a while back. Is this still the case or has this ability been removed?

I'm hoping so. I recently put together an ITX system using an Asus H81I-PLUS and, temporarily, a Celeron G1820. I've updated the BIOS to 2001 (known to unlock the multiplier functionality) and will be ordering a Pentium G3258 shortly.

I'll let you know how I get on

It seems to be hit or miss. Asus boards seem to be best. MSI boards to be avoided if overclocking is the intention as they are sticking to Intels line of no clocking outside of Z97. Going through the various G3258 threads I came across four boards that definately work. They are:-

Asus B85M-G - Best result seen 4.5Ghz (cpu ran out of steam)
Asus H81M-plus - Best result seen 4.7Ghz (also 4.5Ghz)
Asus H81M-E - Best result seen 4.5Ghz (stock cooler)
Gigabyte B85M-D2V - Best result seen 4.4Ghz (stock cooler)

My wifes Gigabyte B85M-D3H overclocks my 4670K and has a full set of options in the bios but it's a rev 1.0 but it looks like they have crippled the latest rev 2.0 with a 1.2v vcore limit in the bios. Bloody shame because that would have been a cracking board for the G3258.
