Overclock non-K processor

[_Grid21]

So I got kinda curious about overclocking a non-k CPU and I wanted to know if a 4790 non-k on a Asus Z87-A Motherboard could overclock my CPU? The UEFI bios has a performance mode and I also was watching this video and wanted to know if it's possible? Just wanted to try it and see but wanted to ask more experienced overclockers here first. If I did try it, would I have anything to worry about? Does Prime95 work on Windows test to stress test the CPU? I have a this CPU cooler Artic Freezer i30 Intel CPU Cooler - 2011, 1150, 1155, 1156 Socket, 320 Watts Max. Cooling - UCACO-FI30001-GB 

 

Let me know and thanks in advance.

You can raise 1 (maybe 2, with luck 3)mhz on the Bclk of haswell before it stops working. That's a 100mhz boost, which really isn't much.

 

Unfortunately, Intel locked us out of Bclk Ocing with 4th (and 5th) gen CPUs. Not really much to do about it other than cry in a corner...

Why oh why Intel... :c

 

Got mine to 104 once and then it hated me.

Is it still worth a go for kicks? Would I burn anything out? I overclock my memory because it had XMP support, 1600Mhz does make a difference I might add, but I wanted to know if I either A. click that performance mode option in UEFI or B. did it myself what would happen?

Yes and no. (Answers to questions in order)

Just saying, don't let your memory get too far away from it's recommended speed.

Not really and no.

1600mhz is just the default for Haswell. An actual OC would be 1866mhz and above.

My other question is, if my base is 3.6Ghz, my boost is 4.0Ghz, why is my CPU always running at 3.8Ghz and rarely goes to 4.0Ghz? Wouldn't overclocking just a bit force it to run at 4Ghz at all times?

Look at this table, it should help you understand why: http://www.intel.com/content/www/us/en/support/processors/000005523.html

OCing the BCLK wouldn't help with that. You see, clock = Bclk*Multiplier. What you are changing is Bclk, but what makes it run at 3.8 instead of 4ghz is the multiplier so...

 

You can maybe change the boost to force it to all cores rather than per core. Maybe. I don't know your mobo to be sure.

My motherboard is a Z87-A. And what does bclk? Base clock?

Again, I don't know if you mobo has that function or not. Most likely yes, but I'm not sure.

Yea, it's just a common abreviation.

So should I go see what is possible?

 

EDIT: If so, what value am I looking to change?

Yeah, browse your Bios for it.

Look for something like "all core".

After that, and if I see that value, what would I change it too?

That's what you should change it to. Look for something that has "all core" as an option and set it as such.

My z97-k allows you to set turbo 3.9 on all cores... as well as the cache multi. While under load it does not declock to base clocks, which is great that it stays at 3.9 across all cores when under load.

I still have speedstep enabled too.

 

Bclk i got to 106.7mhz for 4.12ghz somewhere.

 

But after months.. my board is limitedly fucked. USB port shorts and causing bsod when i turn my lamp on n off. Ikr..

 

Amongst it now not liking my asmedia usb3 ports, the Intel ones are fine tho.

 

 

 

Has its risks going too far.

I think I'll just leave things as it is. I'm having trouble with OCing my 980Ti and had to settle for a less OC then I wanted. Crashing my system too much.
