Skylake Non Overclockable Overclocking guides?

[UnknownSentientBeing]

Ive been looking for some guides on how to overclock my 6500, but I cant seem to find any comprehensive guides on it. Yes, I know I should have just gotten a 6600k, but its been a while and I cant go back in time. 

 

If youve done it yourself, what guide did you use? I know I have a compatible mobo, have the bios already, but have no idea after that.

 

Ive looked for them but the best ive found so far was a sparse guide from 2015.

BLCK overclocking or special motherboard overclocking, since the former won't net much on an i5 compared to something like an i3, and the latter requires special motherboards which are both not worth the extra money and not actually supported by intel

You dont need a special more expensive mobo. Just one that supports it. I already have one.

Intel posted a micro-code update which prevents any overclocking of the non K CPUs, so you're pretty much out of luck with any modern BIOS.

 

You need a motherboard that can do it of course, but you also need to flash BIOS from before the micro-code update before you can overclock a Skylake CPU.

 

In order to overclock, the only thing you can do is increase the BCLK (base clock). Keep in mind that changing that also affects the speed of your RAM, so you'll have to lower it down to its rated speed... this is why overclocking guides aren't really posted on non K CPUs anymore.

I thought they were more money, eh whatever then it should be similar to standard overclocking then just since the chip is a lower bin you might want to be more conservative with your overclocks and don't expect the same levels as that of a k series chip

 

But essentially it's just raise clock speed test, if crash raise voltage (until you either hit a temp wall or a safe power limit wall)

Asrock made a second line of OCable motherboards to my knowledge

Im pretty sure I already have the right bios (f4c) a variant listed on the overcloackable bios list I found.

Alright... if you can adjust the BCLK and voltage to your CPU you're good to go. Otherwise, either the motherboard doesn't support it, or it's the wrong BIOS version. Remember, work your way up slowly with overclocking, and make sure to use something like AIDA 64 to monitor temps when using their stress test for about an hour at your desired clock. Safe temps are below 80 C, including individual core temps. I'd only touch 75 C to be honest.

 

When changing BCLK settings, it also adjusts your RAM speed, so make sure to adjust it and don't let it sit at a rating wayyy higher than it supports.

Sooo I just did that, set my ram to 1866 (its rated at 2400) so now 1.3125 x1866 gives me 2450 which Im assuming is close enough to spec. 

 

Set my bclk at 131,25 and voltage to 1.2. In the bios right now its running at 4200mhz.

 

As a side note, just in the bios alone My temps are already up 5 degrees o_0.

 

I think its of note saying that I only want to oc it to 6600 levels. I just dont want my 1070 held back.

Just take is slow, lower the RAM speeds as you up your BCLK, and try to get as many Mhz as you can before the temps start holding you back <3 :3

I have no idea what Im doing so i think Il just be fine with 4.2.

 

Oddly taskmanager says its running at 3.19, but gigabytes software and cpuz both say 4.2

 

The temps though are what worries me. Theyre really low while running prime 95. It used to go up to 58, now its only 51

Impossible... there's no way that the 212 Evo is producing those results, check with AIDA 64 please >.< just get the trial, go to Computer -> Sensor, then click on the tools menu and open System Stability Test, and System Monitor. Run that while looking at your temps.

All the cores say 100 (guides say they will stop reading correctly) but the package and cpu stay at 44 with fans running at max. I dont get it either.

[UnknownSentientBeing]

Is there any cpu bench recommended for this? Im thinking maybe I can compare the stock 6500 to this

Task manager is unreliable for reading frequencies. Don't use it.

Not only it's possible, it's actually expected. The reason why Prime95 is so hot is because it can make use of AVX and AVX 2.0, if available. However, one of the downsides of locked Skylake OCing is that you lose all AVX support as soon as touch the BCLK. As a result, P95 has to fall back to the (much slower) SSE 4.1 instruction, which doesn't generate nearly as much heat.

[UnknownSentientBeing]

huh.. so with cinebench I only get a score of 597 despite the normal score being 544. Thats not a linear improvement given the i56500 normally gets 544

Do you know of any bench marking software that doesnt use avx? Or even what the disadvantages of not having it are? Does cinebench?

That's not something I'm well aware of. Rather, I only know well about Prime95; how other programs make use of the available instruction sets, that's beyond me.

Dude, sorry for not getting back to you... this means that your CPU is thermal throttling if it says 100

Seriously. you'll have to lower your voltage/overclock, because 100 C will kill your CPU.

 

You have to keep it at 75 C or below if you expect to use your CPU for more than a year.

if i remember, when OC non-k, the temperature appz cannot accurately report the temperatures.

The non-K BIOS is skipping some parts of the power-management, so there are few things you have to keep in mind:

• The missing power-management will not allow to read out any core temperature. However, you can read-out the package temperature with the tool HWInfo (make sure to stay below 70°C package temperature)
•

• No C-States. CPUs will always run full speed and full voltage.
• No Turbo-Mode.
• No iGPU.
• Intel AVX is screwed. Some benchmarks like Intel XTU use AVX and you will have about 4-5 times lower score. As far as I know no game is using AVX so it’s no problem to use this for gaming rigs. Not suitable for professional usage tho.
• Avoid high memory clocks. Everything around 2600 MHz will be fine.

As Airdeano said,  the core individual temperatures no longer show. They arent accurate. Only the package temp works.
