I went to 1.45v, well just above, but no 4GHz for me! Oh well, I think I'll just stay where I am

Yeah, I am already at 3200Mhz so that's the rated speed. I switched to G.Skill. Used to have corsair dominator but wouldn't do anything above 2166.

Gigabyte just told me it's completely safe to use 1.5v with my motherboard and cpu combination! go figure.

They replied to me saying....
Hello,
After checking with our team the CPU voltage can up to 1.50V.

Doubt your get that high tho as heat will be too much unless you have the best cooling system going.

That's true. I have massive temperature limit to play with. I am in low 60's at 3.9GHz OC so I am more voltage limited right now..
igrone gigabyte with everything.

they are the manufacturer that believes, a 1800x at STOCK should be at 1.55V. yes my gigabyte gaming K7 at idle pushes 1.49V and at load seen it hit 1.55V
im running 3.9 at 1.368V at full load...

long day "ignore"igrone?
Argh I need 1.4 for the same oc
Oh good, it's like that on all their boards then
At stock, all-cores, mine sits around 1.26v under gaming load. If I fix the speed to 3.7ghz (the same as stock!), it prefers 1.406. XFR boost spikes it as high as 1.525 for brief moments. Reading around, I don't think those spikes are dangerous or even unusual, but probably unnecessary 
My only bios option is offset, which I have down to -0.072v and it won't boot any lower so... yeah.
well ive just decided to rag the hell put of the chipOh good, it's like that on all their boards then

im sticking to 3.95Ghz @ 1.380V 24/7 with temp of 68-73C if it dies it dies.
Thinking back switching from my 5930K to 1800x was pointless but interesting. a lot of weird issues with this architecture.
like
Cold boot bug
Weird stuttering in game sometimes when going over 50%
weird voltages
next time i might switch back to Intel. depending on future stability.
@smogsy that seems a sensible voltage for the speed you've got it at Most people are happy if temps stay south of 75, so I don't think you're even ragging it per se. If I let mine have it's 1.4v @ 3.8, it shoots up past 80 degrees within minutes and I bottle it!
But yeah I get what you mean about "weird voltages"... this is mine while gaming, stock with a small negative offset, all cores at 3.7ghz:
To be fair, I've never seen it reading above 1.5, and 1.4+ is usually in bursts of maybe 1-3 seconds and tied to one-core boost. Clearly those big spikes are very short and infrequent. It's possible that it's just a whole new paradigm on voltage use that nobody quite understands yet. What would really help is a statement from AMD giving not only the "safe 24-7" voltages, but the absolute peak XFR that they would expect to see. It's probably something higher than any of us expect and we're all worrying needlessly
Only cold boot issues I have are when I've dropped volts too low, and that really could be down to the "guess the offset" game that Gigabyte like to have us play. If I could actually specify say 1.3v @ 3.8, it might work out fine. /shrug
(And all grumps aside, 44-56 degrees when playing Ark Survival is lovely and cool
)

well if you go by the VID amd thinks 1.269-1.525V is what is required for the chip to run at stock (your screenshot) so maybe their no issue. but when AMD say 1.45V reduce lifespan it doesnt make semse...
when the AMD profile sits my chip at 1.488V 24/7... (stock)
AMD statements make no sense lately including Vega, introduction price.
So what is it AMD is 1.525V safe now in bursts? is 1.488V fine 24/7?
That is exactly my problem. Ryzens exceed what AMD recommended at stock... would love to see them publish an article that explains it in unambiguous terms. The enthusiast crowd is too determined to peek under the bonnet to not be clued up.
*edit* Also, the VID changes on a whim anyway... and my VDD has now caught it up - though not exceeded.
it could be just boards over compensating due to new chip not sure what a good level is yet... but not sure.
Doesn't the 1800X boost up to 4.1ghz though? like I had said before I think AMD are already factory overclocking Ryzen so that it would be a lot more competitive with Intel, they could have probably shipped the chips at 3.4ghz using 1.2V vcore which was a much safer voltage long term - usually when you have a significant increase in voltage for comparitively small gain it's a sign of overclocking.
the XFR is pretty pointless most of the time
if you use 1-2 cores XFR boosts to 4.1 Ghz @ 1.55V.
if you use more than that then the Max boost is 3.7Ghz @ 1.29V
Lets be frank pretty much Most applications + windows will use more than two cores.
so for multi-thread work loads 3.9Ghz on all cores is faster than the 1800x @ 3.7Ghz
if you add threadripper in 4 core XFR then that makes total sense. but 2 core hmm...
