I am buying a new computer system. I would really like to buy a 6-core 5820K, but only if I have a realistic expectation of being able to overclock it to 4 GHz and beyond. In other words, if I can crank up the frequency of the 5820K to match a 6700K, then it's a no-brainer in my books.

My question to you elite overclockers: how high have you been able to safely overclock your 5820K? And also, what advice can you offer that will enhance my chances of being able to safely overclock this thing to 4 GHz or beyond? Any special coolers? Mobos? Techniques? It's all appreciated. Thanks!

From all the research and other videos and everything i have seen, i have personally NEVER not seen a 5820k that is overclocked not be able to reach at or above 4.0ghz.

It seems insanely easy to hit 4.0 on the 5820k and 5930k.

Hitting 4.5 and up seems a little harder (it feels like there is a voltage wall that increases rapidly somewhere between 4.0 and 4.5)

This is how mine was, i had to push above 1.275 volts pretty quickly to get 4.5

Our 5820 on an ASUS X99A board is OCd. to a 40 x multiplier on all six cores and pretty much runs at 38C after thermal saturation all day long. A 40x is quite easy to achieve. The ASUS R9 380 OC Strix card stays at about the same temp. as well. Lots of fans, nine total. Corsair h100i GTX 32GB G.Skill 2400 memory. R5 define case. Only SSDs PCI-e system and 3 other SSDs, The 40 x OC is a good balance between power and temps. for a long and useful life. Extremely stable. A slightly higher OC really doesn't matter much except for really long running projects. How fast you can OC to is nowhere as important as cool temps and reliability. Big investment and all that.
Sincerely,

I like these for x99:

BitsPower also makes a good full board option:

They're certainly not needed to get over 4Ghz though. A good quality 120mm AIO will easily allow for 4.2

I have a 5930k (close enough) with the EKMB and 720mm of radiator and had it rock stable at 4.9, but I've settled on 4.7 for everyday use (voltage, temperature, etc). I had 5.0, however couldn't keep it fully stable......but know there are others that have, so the upper limit is quite good.

For more Haswell-E intros, this is a nice full article:

Have a look at my signature below for the layout of my 5820k, what are you going to be using the 5820k for?

I ask because for gaming this processor is crazy overkill lol
