Core i5 6400: Can it be overclocked.

Hi,

I just went through this article:

http://news.softpedia.com/news/non-k-skylake-series-can-also-be-overclocked-on-the-z170-487931.shtml

So can we overclock a core i5 6400 to say 4.0 ghz on z170. Considering the price of the cpu it would be really great, if it could do such high clock. It would be insane price/performance.

Or the Overclocking is very limited to 300-400 mhz.

no.

That's a rumor article from before the chips launched. It turns out the 6400 and other non-K processors cannot be overclocked, apart from a few percent from BCLK tuning.

I know the i5 6400 has a locked multiplier. I was specifically wanted to know about bclk overclock. Has any one tried and how much overclock is possible through it.

From what I hear i3 6100 could be bclk oc'ed and eurogamer tried it to get 77 mhz after which the processor stop overclocking.

You can try it, not sure how far you'll get with the bclk overclocking. Part of the perk was finer 1mhz tuning on bclk vs the previous version where it jumped in like 5mhz increments. It's not tied to the pcie like it was previously I don't think but believe it's still tied to ram. Typically bclk overclocking is pretty limited and wouldn't expect you to reach anything close to 4ghz.

If you want faster speeds I'd recommend a faster chip or a k series with an unlocked multiplier which makes a far greater difference in overclocking.

As I said, you can only get a few percent overclock on the BCLK.

I dont have the chip, just wanted to know. Still if the chip is good 800 -1000 mhz oc is easily possible via raising base clock. So with a turbo of 3.0 for all cores the 6500 can go upto 4.0 ghz on all cores, its completely possible. But that's just my guess.

Although selected this as best answer. But guys all the stuff said in this thread is coming entirely incorrect. I am running a i5 6500 at 4.5 Ghz and many are even running 6400 at 4.6 and 4.8 ghz.

4.0 ghz is very attainable via bclk oc.
