8700K boost mode when overclocked

[P1Fanatic]

I'm looking at buying an OCUK Prebuild with the 8700K overclocked to 4.9. When overclocked does the boost mode increase stay the same i.e stock is 3.7G and boost is 4.7/4.6/4.4/4.3 depending on cores used. Does that mean if overclocked to 4.9 that boost is 5.9/5.8/5.6/5.5 or is the boost feature lost / reduced once you overclock to that level?

Apologies if its an obvious answer but it's been some years since I was looking properly at PC specs and have not really done much overclocking at all.

Thanks
Simon

I'd imagine it would be 4.9 fixed on all cores regardless of load / number of cores in use. It defineitly won't be 5.9/5.8/5.6/5.5 !

Thanks. That's what I thought but wanted to double check.I'd seen some vids of games with people running this chip at 5g and it was always showing the same clockrate.

This 6 core turbo stuff is new to me. I'd be good if the K CPUs would increase like you say - e.g add 200MHz and the cores all increase the same +200, but I don't think it works like that (?).

If the core is used even mildly it will go to the overclock value and nothing else bar the idle value when idle regardless of how many cores are in use.

If you set for 4.9 and 4/6 cores are used you would see 4.9 for the four with the remaining two at idle, or more likely, fluctuating between idle and 4.9. If in windows idle with virtually nothing running in the background and 0-2% load, you would still see cores going from idle to 4.9 very briefly. This isn't the same workload as 4.9 and 100% load obviously.
