extremely confused with 6700k stock voltages

post #1 of 9
Thread Starter 
as the title says. after searching, its left me absolutely confused with stock 6700k voltages are.

example:
reading this corsair skylake overclocking article they imply stock 6700k voltages are around 1.3v's. i tried searching through the skylake overclocking guide here on ocn but the thread has grown so large its a mess.

then i read articles like this arstechnica 6700k review that states default voltage is 1.2v's.

at the moment i have a modest "overclock" on my 6700k. just a merger 4.2ghz. i've been running it at 1.23v's and so far its been purring like a kitten. i haven't really stressed it though. the most demanding game would be battlefield 4 since it can utilize all 8 threads. i've ran linx with the latest linpacks a few times but not longer than 15 minutes tops. never tried prime since linx tends to be harder on the cpu than prime.

but i come here asking because my friend picked up a 6700k for his latest build and his motherboard, z170x-gaming 7 set his voltage on everything stock at 1.32vs. i remember when i got my maximus viii hero and the motherboard defaulted at 1.24v's. i told my friend he could easily drop it, but he insisted if the motherboard defaults to 1.32vs then it must be 1.32vs.

though he does have a random issue where windows is spamming his event viewer with kernel-whea - something about his processors malfunction and something about processor cache hierarchy error? i searched and all i could find is things talking about faulty cache or something like that. i know hwinfo shows his vid requesting 1.42vs at 4ghz when running linx. where mine requests 1.32vs at 4.2ghz though never gets it since i have my vcore manually set to 1.23vs. to test the board i tossed my 6700k into his and it worked identical to my maximus viii hero with my maximus viii hero cpu setttings.

but back on topic, really, what is the stock voltage for a 6700k at stock 4ghz and its turbo 4.2ghz?

It depends on chip "quality", some chips need less Vcore, others need more Vcore to do the same stock speed.
So intel sells them with different VIDs.
There's a list with VIDs ppl got (in hwbot), If I remember right you can get any VID from something like 1V up to 1.4V. eek.gif

there isn't a set stock voltage for the 6700k? just a range?

wow thanks intel.

At 4GHz, the stock voltage will range from ~1.2V to ~1.344V (ASUS VID). At turbo loads (4.2GHz) the stock voltage will range from ~1.28V to ~1.424V.

if 4.2ghz can hit 1.4v's then how can anyone overclock past 4.2ghz?

i've seen my vid request 1.4v's before when under load at 4.2ghz. but it seems to be running stable, abit for a short time with linx with the latest intel linkpack at 1.23v's. i'm sure if i let it ran longer than 15 minutes it would probably crash. but i can't see it needing 1.4vs to remain stable at 4.2ghz. maybe 1.28 - 1.3vs tops.

if that was the case it needed 1.4vs how are people hitting 4.4? 4.6ghz at 1.35vs and such?

that also brings me into another question. vid doesn't necessarily mean that the processor truly needs that certain voltage correct? its just a base to go off of? or does it truly need that voltage to be true stable under extreme loads? i guess what i'm asking, is vid actually accurate to what the cpu truly needs?

The VID is the voltage Intel programmed the processor to request at the respective workload. Intel probably leaves headroom to ensure the processor stays stable in poor thermal conditions and for any possible degradation throughout the life of the processor.

thats good to know. so even though it requests it, it doesn't mean thats actually what it needs.

another question, do we have to worry about vid ever requesting voltages higher than intels specs? such as 1.5vs?

sorry for all the questions.

edit:
would also like to know if there are any differences between vietnam batch and malaysia batch?

Is it correct to assume a lower VID chip (1.28V) has higher OC potential than a higher VID chip (1.424V) using air or water cooling?

Could you also tell us the 6600K stock voltage range at turbo loads (3.9GHz)?

Intel spec says VID can go up to 1.52V, but I don't expect they'd ever sell a chip with a voltage that high. There is no difference between batches.

In general yes, the lower the VID the better the overclock potential. I have seen exceptions to this though. I haven't paid attention to 6600K turbo voltages, but I've seen stock VID ranges (ASUS) from 1.12V to 1.216V.
