Get Your Flamethrowers Out

Okay So I am using an H170 gaming m3 board and am very disappointed I am missing out on overclocking my 6500. Ill cut to the chase, how stupid am I for even considering the Idea of flashing the bios for Z170 gaming m3 mobo? I mean I am sure they are different in many ways, but I am wondering if the non K OC bios update will brick my H170. I have been waiting around to see if intel is going to shut this down, and in hopes that H170 boards would also get these updates but it has not happened, and I have lost faith that it will.

All of you ought to settle down. There's no place here for throwing personal insults. If you can't keep it civil, don't post in the first place.

Twisted, flashing a BIOS that's not meant for your mboard is a bad idea. Those are customized for each individual component on that board which aren't necessarily shared, even across a manufacturer's own lines. As for overclocking the CPU, why do you feel you are missing out? What task do you put to it that would be significantly improved by a slightly faster clock?

Urchin, even old SB, IB, and HW locked chips could be overclocked slightly using BCLK alone. Skylake has just made the BCLK more flexible. It's still up to an individual board on whether it will allow BCLK adjustment. The...
Don't mess with your bios. Yes this is a bad idea. The i5-6500 is not meant to be overclocked. If you try you will get minimal performance increase and lots of wasted time. They make over clocking chips with a k at the end like i5-6600k for this. No k, no overclock. I'm sure your performance is fine with what you have. Stop worrying about it.
 
No need, I'll just normal punch you once. x)

Don't shut down the computer. If you flash the wrong BIOS, it may kill the motherboard.

And please, n3rdr4ge. For as long as I know you and you joined Tom's you made replies that are either out of date and/or is not helpful. You can OC non-K processors with Z170 by boosting BCLK, but for Skylake and Sandy Bridge and below, BCLK doesn't affect other components aside from CPU.
 
still grumpy over old threads i see. ive helped plenty of people and you've only been here 7 months longer. get a life, for real. i don't trash threads you post in. you started this super lame brawl between us and are obviously still caught up when you see me around.

It's still up to an individual board on whether it will allow BCLK adjustment. The Z170 does of course, and there are some rumors that an H board will have this option, but I haven't seen anything concrete on the latter yet.
 
Solution
A 200 MHz boost isn't out of the question on some locked CPUs. Considering some people can't get their 4 GHz i7 much more than 200 MHz faster than its stock clock, it's tough to call that not worthwhile.

Personally I consider CPU OCing pointless 90% of the time. The vast majority of people don't run any programs that significantly benefit from the extra time, effort, and money that it takes to do so.
 


glad someone else thinks this.

Yikes guys.. Well my desire to donates from the fact that I am old school and run two i7 870s and an E8400. Both of these chips can be overclocked using bclk. My gaming rig has(now had) an 870 clocked to 4.2Ghz which makes almost a 10 fps difference in TW3. I fully understand that in most cases overclocking is in needed now and to be honest I am getting the same frames roughly after the upgrade. I know my post is such a noob question that everyone will think I am... Well a noob, but I have been at this for a while so I guess a better question is this. If two boards differ purely in firmware, could a bios for one be flashed onto the other?

As far as missing out, it's just annoying that $40 would let me play around a little more and find yet another thing to keep me from putting a dent into my steam library. I largely agree though, Overclocking is mainly done to say you did it and provides marginal gains while trolling on forum's.
 


Understood.



Uh... For Sandy Bridge to Haswell, if you mess with the BCLK it raises the clock of everything (CMOS excepted). It's on Skylake that BCLK only affects the CPU and not other components. That's why Skylake has been getting some noise recently, with the slew of board manufacturers flooding out BIOS updates.
 

Yes, the BCLK is tied to other things on those chips so you can't change it a lot, but that doesn't mean you can't touch it at all. Read some of my motherboard reviews. Most boards can be stable up to 105 MHz. One Asus model that recently went through my bench was able to hit 108 MHz stable. That doesn't seem like much, but on a 37 multiplier locked chip, that's a 185 - 296 MHz potential boost. It's not a huge amount, but it's something.

I fully understand the Skylake broohaha. Yes, you can possibly take the BCLK up to 120 MHz and above. Yes, this makes things like locked i3 and i5 chips more exciting. Mboard mfrs have been bypassing Intel's lockdown for a while now with H81 and B85 boards that can tweak CPU multipliers when only Z boards are supposed to be able to. These BCLK changes are why Intel is not letting the E3v5 Xeons work on the normal Z, H, and B chipsets. No one would buy a 6700K when you could get an identical Xeon for less and take it above 4 GHz on a BCLK tweak.

Twisted, no, even if two boards are near identical, I still wouldn't try flashing one BIOS onto the other. It's just not worth bricking your board. You saw such dramatic increases in OCing your old CPUs because that helped them overcome their relative inefficiency compared to modern microarchitectures. With a modern CPU, it no longer has that weakness so OCing is often not necessary. Check this for some detailed bench numbers regarding CPU speed and type.
