Intel I5-6500 clocks

[Dpg3456]

Hello all,

I have a friend who wanted to overclock his system but I noticed that his cpu is not a k series chip, so its locked. But I heard you can change the clocks through different profiles or something like that. Can anyone clarify for me?

There are some "moded" motherboard bioses available for locked sky lake CPUs.

As you see from reading these articles, there are drawbacks.

So he would have to flash in a modded bios version? Or would the stock bios be able to BCLK oc?

Standard bios might allow a slight OC of a few % but not worth the effort. Modded bios would allow you to turn it up much more, if you can live with the new problems it brings.

Without a modded bios you can usually get by with a very small increase in the bclk before gross instability occurs. I mean like maybe 200-202.

What type of problems?

200 mhz is not worth the effort right? I mean for my computer id go for it. But for my friend I dont think its worth the hassle it will be for me to try and explain to him how to do it over discord.

I'm a bit rusty so you'll have to research in case I missed any, but the biggest ones to me are that AVX is broken (it still works, but slowly) and you lose access to the on-CPU per-core monitoring. I think the overall CPU temp is still present, unless it is something else measured by mobo... think there was something about losing power saving states but I don't think that to be a major problem.

Would the AVX hinder gaming performance? I don't think the others are to important.

Another problem is that I think you lose all the power management technologies so that it's running full frequency all the time. Also realize that there aren't modded bioses available for every motherboard out there.

Now idk about Intel, but I run my AMD chip full frequency 24/7. Can Intel not do that?

 

[trents]

Sure, you can do it if you want but it will make more heat.

Probably not. For example, Ryzen is similarly weak in that department, and Celeron/Pentium level CPUs don't have it at all.

I run my Intels 24/7 with Prime95 like loads. My power bill is less fun.

Yeah I understand. He is running the stock intel cooler. What cooler do you recommend he get? Would a Hyper 212 Evo suffice? Or would it be better to get a 120mm CLC?

Okay those negatives dont seem that bad. I run my fx 6300 at 4.8 24/7. Now that is a nice power bill...

Concerning the cooler recommendation, does your buddy have a budget and is he open to water AIO? Also, what is the make and model of his case? Cooler options can be limited by lack of clearances in the case, particularly to the side panel. Many of the best air coolers are tall. But the Cryorig H7 is a lot of bang for the buck and enough shorter than most other coolers in it's class to fit in most mid tower cases.

 

[Dpg3456]

His case is the NZXT S340. And he is on a tight budget as well. Would the Cryorig H7 provide a decent overclocking headroom?

On an i5 6500 indeed it would.
