Question 1

Can someone please tell me what the stock cooler height is for this processor?

Accepted Answer

The stock Heatsink/Fan that shipped with my 6420K measures 1-7/8" above the motherboard to the top of the fan assembly. Additional clearance above the fan is needed for proper airflow.

Question 2

I have a Dell Radeon 6450 1gb Discrete GPU, can I crossfire it with this cpu? I know it says that a 6450 is crossfireable, but I dont know if since it is a dell card from a pre-built system if that would affect anything. I also must add that it is working in a pc i'm running now, but i have not crossfired it with anything.

Accepted Answer

They must have the same (or compatible) core architecture. My guess is that the 6420k won't work with a 6450. This form won't allow links, but the support dot amd dot com page has lots of good stuff.

What you are looking for is Duel Graphics, the term that AMD uses for a GPU + APU. I can't find the 6420k on their Crossfire/Dual Compatibility Chart, though.

Testing it shouldn't be too risky, it will either work, or give you error codes.

Question 3

Does anybody know if this is compatible with a A78M-E35 MSI motherboard?

Accepted Answer

Yes it will but if this is a new build I would go with an FM2+ Processor Like an A10-6800K or A8-7600

Question 4

Will I be able to play World of Warcraft on max setting with this APU? What would the fps be?

Accepted Answer

World of Warcraft ...Maybe. But I doubt it. The best thing to do is buy a cheap compatible AMD video card and run it in crossfire mode. Then you should be able to crank up the settings to max. Happy Gaming:-)

Question 5

Will this processor work with GA-F2A78M-D3H motherboard?  It is not listed on the compatibility list from giga-byte.  Thanks ahead of time.

Accepted Answer

According to their site, it is compatible with this particular Richland, along with many others.
