So I bought the Asus B95M-G recently and it turned out that the BIOS version is too old for the i7 4790k that I've installed. Usually there's no information on the BIOS version when buying a motherboard so how can I know for sure that it's new enough to support the brand new CPU?

 

I'm interested in buying Asrock B85M pro 3 now. Does anyone know what BIOS version it has out of the box?

 

Thanks!

Sangre,

 

You are better off getting a motherboard that has the Z97 Intel chipset in it. 

 

Here's one motherboard that would make an excellent choice for the i7 4790k.

 

 
Motherboard: Gigabyte GA-Z97X-Gaming 3 ATX LGA1150 Motherboard  ($121.99 @ SuperBiiz) 
Total: $121.99
Prices include shipping, taxes, and discounts when available

So the Z97 chipset is a guarantee of compatibility with 4790k? The Gigabyte GA-Z97X-gaming is a bit of an overkill. I'm not looking for the SLI support.

Sangre,

 

You were not specific as to what your needs were. I was not even considering SLi or Crossfire support.

 

I was looking at the Z97 Intel chipset motherboards.

 

The Z97 Intel chipset motherboards is very compatible with the i7 4790k processors. 

 

Here is another optional motherboard for you to consider:

 

 
Motherboard: Gigabyte GA-Z97-D3H ATX LGA1150 Motherboard  ($111.99 @ SuperBiiz) 
Total: $111.99

Thanks Serpius. You've pointed me in the right direction.

A less expensive alternative would also be the GIGABYTE GA-H97-D3H LGA 1150 Intel H97 which also supports that CPU.  It isn't as high-end as a Z97 board, but it will work.  The GIGABYTE GA-H81-D3 LGA 1150 Intel H81 will also work, but this is considered more of a budget board with features and limitations to match.

The Z97 and H97 boards should all work with the "Haswell Refresh" CPU's out of the box as these chipsets were released at the same time as the newer processors.

 

The older H81, B85, H87 & Z87 boards also work but some need a bios update.  This is more likely if the board is old stock and has been hanging around in a warehouse for some time...  I've seen some retailers will offer to upgrade a BIOS for you, but not many offer the service unfortunately.

 

As you are buying an unlocked "K" series CPU, be aware that only Z chipsets officially support overriding the multiplier setting, if that is a feature that is important to you.

I'll run it in Turbo Boost mode at first and monitor the temperature. If it's not to high I'll try tweaking the multiplier a little.

That's why I recommended the Z97 Intel chipsets motherboard so that the person getting the 'K' series processors can utilize the full capacity of the processor if they choose to overclock the processor without having worry about the motherboard limitations of non-Z97 chipset based motherboards.
