PC restart loop after small over clock of non K processor.

[76561198813863277]

I have an I74790 processor (non K) and Windows 7.

I recently changed the BLCK settings from auto to 105.0 which forces the boost clock to 4ghz on all cores as opposed to the previous 3.8ghz on all cores.

I have been playing games fine with it and no issues what so ever but for some reason, when I start my coputer up after it's been off for a while it will go into a continuous restart loop.

This does not happen if I turn the computer off for a few minutes and turn it back on agian.

Altering the blck changes the timings for everything on the system not just the CPU speed, making what is frankly a large jump, I am amazed there is any stability at all, given that the change will have very marginal performance increase I would set it back to stock.

I am more surprised how the system is stable apart from on start up.

Do you think it would be fine for me to start the computer up in the default settings and then restart to change to desired BLCK settings (OC) but close down again with with default settings? as the system itself once running is fine.

do not overclock the blck settings, that is bad. leave stock.

[Monk]

No, in fact, there's a chance it is reverting itself back to stock when it has issues booting, messing with the black is a bad idea and is offering no real gains, just revert to stock, have you confirmed that the increase is actually taking ?

It is bad idea to overclock non-k. Non-k mean they don't have equip for overclock.

What determines the actual K then aside from possible base speeds maybe? Im just thinking delid?.

As for OP, I obviously have no clue sorry

The K CPU's are unlocked. Means they have an unlocked multiplier which you can change in bios with a Motherboard. For a 7700K the multiplier is 42 with a normal bus speed of 100MHz => 42*100MHz = 4.2GHz.

To overclock you simply change then multiplier now to 50 in which case the CPU if able would run at 5.0GHz but not turboboost anymore.

That's not correct especially not with 4th Gen.
You can overclock locked CPU's just not the easy way by simply changing the multiplier. Befor Skylake it wasn't even hard to use the other OC Methods while since Skylake you need workaround with older Z170 MoBo with early BIOS versions

I can't find evidence that non k can overclock. So I'm afraid that I have stated it correct.

You change the bclk frequency instead of the multiplier techincally you are overclocking the cpu but its a dumb idea bclk changes all the frequencies which makes it a lot harder to dial in stability issues

tooked me 5 seconds on google to find evidence. Just because you have no idea and cant google the exact same I stated doesnt mean you are correct...

It is not overclock, that is turbo mode. Nor this guy change BCLK. So no, I'm not incorrect.

It is possible with BCLK yes, but it is not like i3 540 that I used to overclock up to 5 GHz. Every if it is possible to have 15 MHz more to BCLK, it wouldn't exact stable. I did that on my old i3 third gen.

its not tubo clock, turbo clock would be 3.9GHz on 1 core while 3 disabled. Running 4 cores at 3.8GHz instead of 3.4GHz is exactly an OC.

Besides that you need to admit in the enxt paragraph that it is possible countering your own argument that your right that it wouldnt be possible.

And Hardcore OC Enthusiast will highly disagree that you cant OC real high. you just need to find stability for everythign which is harder and change (lowering multipliers) everything else too espcially RAM and GPU multipliers.

I have evidence that it is turbo mode, not overclock. http://www.tomsguide.com/forum/id-1977348/unlock-4770.html

Turbo is stock setting, anything manually increased beyond stock is an overclock, forcing g all cores to run at the single core turbo is overclocking.

You can overclock non K chips, it's just I'll advised as the bclk can mess up the entire system and is very hard to get stable.

Edit.
Also that forum post doesn't show anything g beyond that those posting don't know what they are on about.

I called it an over clock basically I changed the BLCK setting from auto to 105.0 and I stress tested it and it ran all cores at Max 4ghz, before I did this all of the threads would only run at 3.8ghz.

But as you guys said, I could damage my computer so I restored it back to Automatic.

It didn't seem to show signs of instability other than when the computer

I have read a little into how it can damage the computer but I don't really understand it and it didn't sound good (damaging hard drive data) so that was enough for me to change it back to how it was before.
