8+4 pin cpu power

[HardStroke]

i have a gigabyte vision g and a 10600k

i will be overclocking it to at least 5.1ghz so my question is, do i really need those extra 4 pins?

voltage will be left on auto

Yes and more importantly DO NOT LEAVE VOLTAGE ON AUTO.

why not?

Because almost every single time you can get lower voltages on same clocks, reducing your temps. Main issue is that not every CPU overclocks the same and manufacturers have to keep that in mind when creating voltage curves.

10600k does not need the extra 4pin, it's only the 10 core that mandates it so far.

 

But auto voltage, that's a bad idea. Auto voltage either is set too low and the system gets unstable, or it's too high causing at best higher temps than needed, at worst send too much voltage and damage the CPU.

so should i try 5.0ghz on a lower voltage set then default?

what if ill do something wrong?

does a cmos clear fix that too?

right now im running an i5 3550 with a 4ghz overclock and voltage set to auto.

maximum temp that i got while rendering was 65c

never got past it

no matter what i did

Didn't you already ask about the extra 4-pin power in another thread?

(Or just TOO many people asking the same question about the extra 4-pin or 8-pin in the last like....week on LTT).

Extra 4-pin power is not required, unless you are going for 5GHz+ on the i9-10900K, or shooting for some kind of 6GHz+ on your i7-10700K using liquid nitrogen to cool the CPU.

The single 8-pin already supplies up to 384W to the CPU.

 

Do not leave voltages on Auto; they can sometimes Auto too high, and cause damage, especially when you start overclocking the CPU.

If you can do 5.0 / 5.1 GHz on lower voltage, then do so.

With overclocking, you should be using the least amount of voltage possible.

Ivy bridge and comet lake are two completely different beasts.

You cant overclock a 3550, unless you're talking about the 3570k. 4GHz is pity for Ivy Bridge tho, 4.5GHz is still plenty conservative at least when they are new (before they degraded over time)

nah i never asked that here

im just not used to that need of more connectors and power lol

my current i5 3550 just uses a regular 8 pin power connector and thats because of the motherboards revision - 1.1, the previous - 1.0 rev only uses a single 4 pin connector so i guess they updated it to deliver more power and better oc capabilities.

even when switching from a gtx 650 to an rtx 2080 i saw in shock by the need of connectors this card needs. two 8 pin connectors compared to one 6 pin

do you have a voltage recommendation in mind??

no, i know that i have.

its an i5 3550

a 4ghz overclock is actually really high for this cpu, not ivy bridge in general

i got it to 4.1ghz but there was no big difference so i tried 4.2ghz and learned that 4.1ghz is the limit with blck and a 39 multiplier so i just returned to 4ghz

Since you have more cores and threads, it will require more voltage to get 5.0 / 5.1 / 5.2 GHz all-core overclock stable.

It seems to vary from one CPU to another, voltage ranges from 1.3V ~ 1.36V to get 5GHz+ stable.

I'd say start at 1.3V, and work your way up...

 

Be sure to use the most suitable CPU Load-Line Calibration setting.

Too high LLC and it can overshoot the voltage, too low, and the voltage can droop too low, making the CPU overclock unstable during load.

I mean overclock high with multplier as much as the silicon can take. I remember now that locked Ivy Bridge (non-K, basically) on Z chipset board gives you 4x increase in multiplier limit and ability to raise BCLK by at best 7% (usually 5% tops), you're not reaching the limit of the silicon yet which is why auto voltage is still viable. 10600k on 5.1GHz on the other hand, is an above average result since Intel puts most of their 5GHz+ silicon to 10700k and 10900k. Your CPU will need every bit of help to go that far while staying safe.

so after setting the multiplier to 50

i should just try voltages between 1.3 and 1.36?

if the voltage is not perfect the the oc is not stable, will it wont boot? or will i get a crash/blue screen/bios notification?

so a cmos clear will fix it back to default right?
