Post your stock voltage overclock

How far can you push your 4670K/4770K (or any other OC'able CPU) on stock volts, whilst retaining LinX/Prime95 stability?

Thanks.

So, 4.2 on stock with the 4770k. 12 hour Prime95, zero errors, never went above 71* C.

I've been told to lock my doors and hide in the basement. 😀
 
My FX-9370 did 4.9GHz stable on the stock 1.49v. I'd test and take a screen shot, but my fan stopped working for an unknown reason. I'm probably the only person running a passive cooler on a 220 watt TDP CPU. 😀
 
I get 4.2 on my 4670K, at stock voltage. Stock cooler though, and I don't run it like that. I run it at 4.0, stock voltage.
 
+0mv offset @ 4.3GHz with LLC at the lowest setting results in 1.168v under a 4 core load. Stock voltage seems to vary tremendously between chips.

Auto is fine. Thanks.

um if auto is fine then I know I can do at least 4.5 perfectly stable since voltage "automatically" goes to 1.275. I did not try to go higher.

I settled on 4.3 with manual adjustment of 1.185 because I wanted to stay under 1.20.
 
I once had a Q6600 that would do 3.3Ghz on stock voltage, I thought that was pretty good.

OCed it to 3.6Ghz, at still a fairly low voltage (1.32v, something around there), and sold it to a friend, still overclocked.

You need to completely disable llc to get stock voltage.

I thought i could get higher too, but at 4.3 it crashed on boot. I wonder where these voltages come from, are they built-in/requested by the cpu or is it the mobo choosing them?
 
I'm not sure what the VID actually means, but in my experience it has no clear relationship to the actual vcore as displayed by cpu-z. At 4.2 my cpu's VID is reported as 1.241 but actual vcore is 1.112. Also, VID changes depending on frequencies.

Yeah, but if you put the CPU on another motherboard, the overclock stays with the old motherboard.

The minute you put another cpu in the "old motherboard" in that case, there is no overclock, it resets. Stop arguing a position you can never win.

The CPU is the only thing that is ever overclocked.
 
4.0 at 1.050V locked. tbh i was hoping for more.
my chip really doesnt like running faster than 4, it needs 1.30v to run at 4.3 so ..

what ? why would it?
overclock is nothing but BIOS settings. if a new cpu is compatible with those OC settings it wouldn't reset.

Lets put it this way.

The motherboard has the settings you adjust to OC the CPU.
But the CPU is the one that is running faster.

When the you put the CPU in a new motherboard the settings arenot transfered to thr new mothetboard as they are stored in the memory of the old motherboard and not on the CPU, so there is no way for them to transfer.

I have already won:

"The overclock is done on the motherboard, not the CPU."

To sell an overclocked the CPU is like selling an a computer monitor with a very nice wallpaper.

What I said?

The dude just said he sold the CPU with the overclock, and I just went "wtf?" because the overclock stays with the motherboard, not the CPU. Because the overclock is done ON (not "to", "on) the motherboard. To the CPU, of course, but that's besides the point.

Can we please go back to discussing the question at hand?

Define 'stock volts'? Leave it on auto or manually lock it to the actual stock voltage?

Stock volts varies from my chip to your chip to their chips.

To find yours just set uEFI on normal with zero offset. Running stock clocks load it with something like linpack11 and view your vcore.

Auto vcore can be way, way higher than needed for stability.
