Questions about the Turbo boost of i5-6500

[khrystiano]

Hi, I have an i5-6500, MSI 970, 8GBs DDR3 and a Asus H170M-Plus and I have a question.

I know I can't OC my CPU just because of my mobo, right but I have heard about the turbo boost mode and I've read that in my CPU it can reach 3,6ghz (my cpu is at 3.2 default) but just in one core, the turbo would work like this:

1 core------ 3.6
2 core------3.4
3 core------3.3
4 core ----- 3.2 ghz

So, my question is if there is any way to put 3.6 ghz in all cores or at least 3.4 in all cores.

Nope. That system is locked.

And it's not quite that linear anymore. With Skylake they revised how Turbo scales so you might see slightly different ( higher ) clocks with different core loads depending on temps.

Yep, I've seen different clocks with different core loads in certain situations.. So, there is no possibility, right?

Well, one more question, what config would be better for games (Like The Witcher 3 and similar), the config I have or a GA-Z77-DS3H + i5-3330?

The i5 6500 is faster than the i5 3330.

 

[khrystiano]

Oh, mm but with the 3330's moba and doing some oc, wouldn't be the 3330 faster than the 6500?

The 3330 is still locked. You can only overclock Intel 'K' series CPUs. There was some ability to overclock via Turbo in past generations but Intel did away with it in later BIOS and it was only true for a little while. Even then the 3330 maxes at 3.2Ghz with Turbo so that's the max clocks. The 6500 is a newer architecture as well so even at slower clock speeds it's a faster processor than the 3330. And the 6500 is way faster with a 3.2Ghz base/ 3.6Ghz Turbo.

Oh, now I see, thank you.

But im interesting about the latest BIOS.. so If my moba have an older version would I be enough luckily to OC in Turbo mode?

No. It was only on some Ivy bridge chips I think. It might have been first gen Haswell. It's been disabled for years. I thought maybe that was why you thought you could overclock yours is the only reason I even mentioned it.

Limited oc was on sb and ib and is a feature so will never go away. Haswell never could and the only thing that was disabled was the unintentional oc capability on skylake. Limited oc is 4 bins above max turbo speed and with the turbo loophole, you can get that on all cores. I don't remember if gigabyte had that on their mobos. But the 3330 at 3.6ghz is about the same, possibly slower than a 6500 at 3.3ghz because of the ipc increase and higher turbo when less cores are used. It should be 3.3 not 3.2 on all cores. Also the faster ddr4 ram, other improvements and instruction sets could also help.

It wasn't a feature it was a loophole and it was disabled by Intel. You needed an overclock capable motherboard to start with and later BIOS revisions shut it down. Sandy Bridge could do it but I think later microcode revisions shut it down on Ivy. I know Haswell couldn't do it.

Intel themselves released slides about the feature. Multiple actually over different conferences and events mentioning a limited or partially unlocked capability. https://www.google.com/search?q=intel+limited+oc&rlz=1C1CHBF_enUS727US727&source=lnms&tbm=isch&sa=X&ved=0ahUKEwiyvNqNyfbVAhVk64MKHbLFAiQQ_AUIDCgD&biw=1920&bih=950 The only loophole was having turbo max speed running on all cores and intel stated it technically was still within the boundaries of the turbo function and let it go.
