You prove my point that people will do things, even crazy things, in the absence of real data + the pursuit of a numerical goal (in this case, GHz).From multitude of topics on XS AMD sub-forum. There are many FX users there,check it out.
Exactly, and that's why I had to question your "1.55V should be max safe vcore" post, because such a message is presented as authoritative, when in fact, and as you so admit here, it is just people guessing and "well, it's not dead yet".We only have some data from forums like this and AMD won't give you a real answer on just how much is max. safe Vcore
I guess English is your 1st language?Exactly, and that's why I had to question your "1.55V should be max safe vcore" post, because such a message is presented as authoritative, when in fact, and as you so admit here, it is just people guessing and "well, it's not dead yet".
At least in the Phenom II era, we had AMD's guidelines to fall back on, as well as their published voltage ranges for each SKU.
Yeah I found out earlier that the specs are lacking for most things 32nm. But that isn't just AMD, Intel too won't publish max Vcc specs for Sandy Bridge or Ivy Bridge.Exactly, and that's why I had to question your "1.55V should be max safe vcore" post, because such a message is presented as authoritative, when in fact, and as you so admit here, it is just people guessing and "well, it's not dead yet".

1.55V should be max safe Vcore you would want to run your chip on. Make sure temps don't go over 65C and it should be OK.

I don't want this to devolve into a grammar discussion. If you thought you weren't being authoritative, so be it. It is moot now anyways, since the succeeding postings from both of us have hashed it out very clearly that it is, in fact, from a source that is not official at all.I disagree. Should be is not equal as "1.55V is the max. safe voltage" . First one is a suggestion by me, second is authoritative statement.
Apology accepted, no harm doneSorry.
This has also been my observation with my own Thuban, and also my own behavior/decision-making regarding safe voltage OC settings. As long as the Vcore ends up less than what TurboCore would set it to every time it turbos, I call it good. I can't believe I completely forgot about this. :facepalm:AMD sets its turbo voltage crazy high, so I've always my kept my 24/7 OCs under that. I haven't played with my 8350 yet, but my 1090t turbo voltage was 1.475v yet stock volts were 1.30 (or maybe 1.35v). Either way, plenty of room for a nice OC, especially since the max multi is 18 (or 18.5 with half steps) for CnQ to downlock during idle (again, for Thuban).
@OP did you not cover the contacts on intel processors? In other words u used your hands directly without covering the processor contacts in any manner?
Are the AMD chips still shipping with their pins lodged in a sort of little black, stiff, plastic-y fabric mat? I've used that to afford the pins a little protection when lapping in the past, under the assumption that if it was okay for the manufacturer to package it like that, it shouldn't cause problem.Idontcare said:Now most people, from what I gather, use a styrofoam block to cover the pins before lapping their AMD chips. I intentionally avoided this because I was quite keen to avoid risking an ESD (electrostatic discharge) event and insulating dielectrics such as styrofoam are notorious for accumulating surface charges.
Thanks for the great thread Idontcare! It's a fun read, as usual. (and oooooh the shiny!)
But I was wondering, with regards to the bent pins and your comment

And I'm wondering if you would extend the above quoted comment to that material as well.
Gotta try this lapping myself,i got a old dell with a pentium 4 that i could use as a test to practice on,would shake like a tree lapping my 3930k.:awe:
Wonder if the improvements on my chip would bring anything to the table?
So, IDC, what's the max TurboCore voltage you see at pure stock settings? That seems a reasonable data point in finding a max safe Vcore for the 8350.
I would say 4.8GHz is not sustainable for this chip given the voltage and power bump it takes. At least not at the air-cooled operating temperature that goes along with it.
idc, have you had a chance to test with the h100 yet?
eagerly awaiting more great reads from u
Did I forget to do my H100!? Doh! :$
I've been busy building out replacement boxes for my aging Q6600 rigs and for some reason I had convinced myself I was done with the FX8350 for now. Whoops!
Things are a little crazy here at homebase as we are in the 11th hour mad-rush leading up to putting our house on the market while simultaneously dealing with all that goes into moving to Taiwan (passports, visas, finding a house, getting kids registered for school, etc).
My "woe is me" whining aside, I have all the hardware sitting on my desk right this very minute so I imagine I'll make the time to assemble it and get tests done in a day or two.
I also want to figure out a way to ghetto-strap my VaporPhase LS onto the FX8350. It scales so well with cold in those suicide OC sessions AMD held a while ago, I got to imagine it will do well under vaporphase cooling provided the heat output doesn't overwhelm the cooling capacity. (I know my vapoLS can handle at least 270W which is what my QX6700 put out at 4GHz)
