YEah a guy on a french forum as the same mobo/cpu than me, but his mobo is a rev1.0, and no double boot problem.

What I thought I intended to say was on a "proportional basis" on (UD3 Rev3) a 40% OC with an 8core will genorate proportionally MORE heat than a 6core under the same roughly proportional 40% OC. Not true?redface.gif

of course u get more heat with 8 core than 6 core.

It is not only the 2 cores but the whole architecture is different as well so it generates a lot more heat.

OT: I'm actually kinda holding my breath to find out if that "P-word" counts as "profanity" here. I've been bit twice now. the last time i replaced the ENTIRE WORD with asterisks. "in context" apparently the asterisks counted.

architecture is the same on the FX chips. All the chips are the same die. So even your fx4100 (example) has the same die as a 8150 etc.

and yes 8xxxx>6xxxx>4xxxx in terms of heat output, though the difference is not really that large, because they do all share the same die.

You must be or you have very good cooling, I've heard from others on different forums that these issues have been reported on all revisions.

I have 520mm worth of radiator. I haven't had any throttling issues since the board actually came out and was on f5 bios with my old 8120. (it would throttle unless you opened Amd overdrive and enabled turbo core and disabled it again), it was fixed in later bios.

Overall I think if you look back before the revision 3.0 posts were made, most folks were quite happy with the UD3.

NO CUSSING IN QBERT. lol

This is what I will say. I have had the 1055t on this board overclocked with a 620. Then swapped over to the 965 Black edition. Temps with 6 core 16c temps with 4 core 28c and on my sig rig I have a 8320 on a asrock x4 that runs 7c. So the number of cores have nothing to say about if you have more cores it will have more heat or be cooler. These are at idle overclock temps. Just keep that in mind games. Nothing wrong with a heated debate or we still might be at a stone wheel. thumb.gif

ABSOLUTLY correct. To those of us who have been here for the last 30-40 pages or so, it is a blazingly (no pun intended), obvious point at this, ... at this point. Agreed.

My original response to mitlkit's post claiming he had the same set-up as Gannon, when what he probably meant to say was the same OC-set-up, which is probably all I should have said. Instead I went on (and on) in a tone that could have been precived as a little patronizing and for that should and DO apoligize, to all, and specifically Mitlkit.

I'm close to if not the LAST person here who has any right to sound like their poo-don't stink. I consider myself privledged to be taken even remotely seriously here.

Considering the relatively useless of Gibabyte "tech"-"support" this thread is pricless.

ok, I'll admit THAT's edging up on being a bit over my head, I just know, for whatever precise technical reason the 8-cores seem to get away with LESS (proportionally) of an overclock than does my 6 core before getting in to trouble temps-wise.
Now, exactly HOW MUCH of a difference there is in that area, is still reasonably up for debate. IMHO. (emphasis on the humble)rolleyes.gif

95W vs 125W alone says a lot to me.

OT: I probably should look into utlizing that Multi-quote thing.....whistle.gif

i am afraid that is not true because i have the 8350 and it is called VISHERA and the others are BULLDOZER and there is a big difference.

So they are absolutely not the same, they do not give the other chips a different name for no reason rolleyes.gif

if they were the same you could buy an 8150 instead of the 8350 because they are the same witch they are not.
