[SOLVED] Should I mess with BLCK for extra overclocking (cuz i really want to :))

[ikplaydebom]

Hello I have done about 4 hours of research about BLCK overclocking and have heard a lot of differnt things. I am intrested to try and want to know enough before i try it. Before I am going to put more hours in researching BLCK overclocking I would like to know if my system is even suitable. This would be a great help!

Here is my system:
Mobo: asus p9x79
CPU: i7 3820 (currently oc to 4.3 gh)
Ram: Corsair CMX16GX3M2A1600C11, 16gb 1600mh 1.5v (8x8)
Gpu: 1060 3gb
Pws: corsair cx750, the older one 80 Plus Bronze
Cooler: Corsair H80 watercooler

With the current overclock (1.35 volts on cpu) i get no more then 60 degrees during stress so i should be able to push it a bit further. I have the luxury of not having to pay for electricity so hell yeah lol. I am hesitand to go BLCK overclock as i heard it could also mess up you ram and pcie slots. I saw a tutorial online with the same mobo and cpu but he said his 1.2 v ram was helping and mine is 1.5 v so yeah. I primarely use the system for csgo gaming so maybe single core oc is also something to look into. I am super intrested to hear what you think. I heard a lot of people from 2015 say they got this cpu for overclocking so i am pretty excited as well. Thanks for reading and i hope to hear from you!!!

Back up your data/system first.

Go ahead.

Here goes nothing....

I got the error message overclock failed. I had put the BCLK on 105 with 1.35 cpu v 44 mutliplier(max) and the ram speed went from 1600 to 1680 and i put the dram voltage cha and chb to 1.550. Is there something i did wrong?

 

[ikplaydebom]

also can i overclock usging the cpu strap?

 

[Phaaze88]

BCLK of 105 is 'way' too high in most cases.
Try 103 max. You really don't have much room to work with. BCLK OC is really finicky; it alters cpu core, cpu cache, and memory frequency all at once.
The first 2 aren't too bad, because one can usually raise the core + cache voltage and be fine, but the memory frequency is the one I feel screws you - the current timings are no longer stable.

Then i got pretty lucky i didn't go further than 105 how ever i see some other guys turning the blck all the way to 125 whilst saying that these are very averadge overclocks. For example 3:00 "most people set it at 125" it just seems strange to me this guys is doing 125 bclk but i cant get away with 105?

Don't bother. Not worth it.

BCLK is a multiplier that affects everything tied to the buss. So ram running at 3000MHz with a 100.00 buss clock will run at 3150MHz If you can sustain a 105.00 BCLK. A 4.2GHz cpu might hit 4.4GHz. But that affects transmission speeds of data, hdds, SSDs, etc.

And adds a lot of unnecessary heat to the cpu since the memory controller is also affected, gpu is affected, igpu is affected etc.

Most modern equipment has stability issues with 103 BCLK, by the time you hit 105 BCLK your cpu just added 10+°C easily.

125 BCLK is generally only done under LN2 conditions to eek out higher core clocks without having to maximize the cpu core multiplier and create voltage instabilities. Many motherboards won't do 125,be limited to 115 maximum.

Then how is it possible i see people with the same cpu and mobo that get 125.003 bclk by changing cpu strap.

Thanks for the reply but what confuses me is that half the people i see say 106 will fry your system and the other half says that chaning the cpu strap to 125 mh and keeping the ram in check means 125 is easy overclocking. I hope someone can explain me why there is such a difference and if i can follow a tutorial like this how to overclock i7 3820 with cpu strap.
