Overclock i5 7400 non k

I've got my i5 7400 boosting up to 3.6 GHz 

Most of the time it hovers around 3.4 GHz 

How is this possible

It's not going to happen. Even with a Z170 or Z270 board, you're not going to be to squeeze more than 3% out of the BLCK, so you'll be lucky to get to 3.4Ghz all core.

Task Manager is not always a reliable source for that info. Use CPU-Z or HWMonitor for accurate CPU clocks.

Correct me if i am wrong, but I swear there was a way to overclock non K CPUs. I don't remember if it was kaby lake era or skylake? I remember you can OC on the bios, not sure what the steps were. I know it was patched now, but mobo, with a bios before the fix could OC a non K chip. I'll try to investigate.

Found the video.

Single core 3.6, all core 3.4. it changes. You can try BCLK tho

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k (won) - EVGA Z370 Classified K - G.Skill Trident Z RGB - WD SN750 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G3 650W - dual booting Windows 10 and Linux - Black and green theme, Razer brainwashed me.

Draws 400 watts under max load, for reference.

 

Linux Proliant ML150 G6:

Dual Xeon X5560 - 24GB ECC DDR3 - GTX 750 TI - old Seagate 1.5TB HDD - dark mode Ubuntu (and Win7, cuz why not)

 

How many watts do I need? Seasonic Focus thread, PSU misconceptions, protections explainedgroup reg is bad

Well, it looks like you did manage to get the BCLK to 102.9Mhz, which is the 3% I mentioned above. That's why you're getting 3.4Ghz instead of the 3.3Ghz you'd get at stock.

 

The boost multiplier is still going to be between 35x for single core and 33x for all core, but a 2.9Mhz base clock difference will be an additional 100Mhz.

I'm running a Asus z270 e gaming Mobo 

With a very old bios revision so I think thats why I can get these results

Nah BCLK up to 102.98mhz is allowed by the Intel Management Regulation the artificial block only applies past this. Skylake that had some actually fully unlock that allowed people run the i5 6400 and i7 6700 at 4.5~4.6ghz so nothing impressive to see here as can be replicated with any locked cpu with an unlocked chipset.

Well, back in the days, there was a H170 Hyper, that a BCLK which would actually let you overclock any non K CPU... no longer..
