5820k // 4790k ---> Overclock

[Redjo]

First i wanna let you know that i never overclock anything on my life till now. 

I will get new computer at the end of this mount probablly but i havent decide my cpu yet... anyways.

 

Ok how far 5820k can be pushed, and how far 4790k can be pushed with Kraken X61 ? ( I talk about stable and long durrable overclock ........ just long )

completely depends on the chip you get. Both can run anywhere from 4.2-4.9GHz (or higher if you luck out). I'd say average OC on the 5820k's is ~4.4-4.5GHz. 4790k's ~4.5-4.7GHz with reasonable 24/7 voltages.

yep.

 

running 4.4ghz at 1.25v on my 5820k. 

 

also i wouldnt bother with the 4790k at this point, 6700k should be out any day.

 

IMO get a 6600k for gaming or a 5820k for rendering or other heavy multithreaded workloads.

yep.

 

running 4.4ghz at 1.25v on my 5820k. 

Wish mine could do that :unsure: but I'm about to blow it out in a few weeks with DICE and get a replacement. Intel PTPP FTW :wub:

and here i wish mine could do 4.6ghz

Ya no. Topping out the same voltage with a 5280k and a 4790k is likely to be 300-500 MHz difference.

Most people can't even get their 5280k above 4500 without extreme voltages/Cooling, while the stock 4790k turbos to 4.4 (which should tell you the difference.)

At around 1.3 volts, I'd expect 4.3-4.4 (4.5 if lucky) on a 5280k, and 4.7-4.9 (although I've seen 5.1 at only 1.32 before) on a 4790k.

I've had some above and below that myself.

How is that not basically what I said?

Average results... The only thing we differ on is where the 4790k's can end up on average. Most samples I've seen don't reach 4.8-4.9 @ 1.3v or under, hence the 4.5-4.7 range. They're definitely more capable from 1.35v-1.4v than their earlier 4770k brother, but this forum is fairly averse to high voltage.

You can reach 4.5 on many if not most cpus at stock. So no what you are saying was not the same.

I said nothing about stock voltages. 4790k, 4.5-4.7GHz within reasonable voltages. It's a range of averages for what most people here would consider "reasonable" voltages.

 

If you show me some data with an average sample number of 4790k's hitting 4.8+ under 1.3v I'll gladly adjust my statement, otherwise I fail to see how what I said was incorrect.

There's some data to support my statement.

That url itself has numerous 4.8s under 1.3.

I mean though comparing stock voltage overclocks (which 4.5 can be and minor overvolts to allow up to 4.7) with what a 5820k can maybe do with 1.25-1.35 V isn't fair at all.

Numerous is not the same as average. If more than 50% of the chips listed could do 4.8 under 1.3v that would be average.

 

I wasn't comparing stock voltages. OP very clearly asked "how far can it be pushed" meaning very explicitly, not stock. I made the qualifier of the range a "reasonable" voltage, set them to 1.3v and see how high they get. How high they get, on average, is what I stated.

Say set to 1.3 (+/- .2 or .1 or whatever volts since no one actually voltage targets when doing real overclocking.

4.5 isn't even on the map for a 4790k.

At that range you are pretty solidly looking at 4.7 and 4.8. Yes 4.7 is more common than 4.8 at that voltage but 4.9 is more common than 4.6 there too.

For the 5820k at 1.3 4.5 is pretty rare. And many even have to pull to 4.3

So 4790k 4.7-4.8 (if you want to include 4.6 you'd have to include 4.9)

5820k your looking at 4.3-4.5 (with 4.4 being most common.)

So perhaps to be fair on average you are looking at a 300 MHz difference at the same voltage.

Obviously this is even more pronounced when you consider a target temperature (instead of a target voltage) with a specific cooling, as the 5820k will take quite a bit more than its fair share to cool compared to the 4790k
