AMD "Thuban" Core (Phenom II X6) XS Overclocking Charts

[cdawall]

a little OT but relating to dumo/cdawalls posts.. ive heard a lot of people talk about the heat these put out but i was always under the impression that 1.5v will put out the same watts/heat whether its 1.5v on 4 cores or 1.5v on 6 cores ive seen chew & now dumo say things that imply otherwise and im just not sure. can someone clear this up? thanks

I was under the impression a 125w chip was a 125w chip regardless to the number of cores thus a 125w quad core that uses 1.35v stock and 1.55v overclocked would output the same heat as a 125 hexa core in the same scenario

You forget that 1090T is 125W, but with 1.28V stock voltage (or at least that's mine). If you get 955 at 3.2GHz but with decreases voltage to 1.28V it won't be 125W anymore.
Well, there are differencies, Thuban core is improved over Deneb, same as C3 over C2, but you get the point. Or..am I wrong?

Your kinda hitting and missing what I was saying all I meant was a 125w chip won't put out extra heat in comparison to other 125w chips regardless to the number of cores. Look at tdp calculators nowhere does it ask number of cores just stock vs overclocked speed/volts so a 6 core won't heat different than a 4 core.

As for the 965 that's not the same as a 1090t it is a 125w 3.4ghz part vs a 125w 3.2ghz part. A 955 125w with the same default voltage would raise tdp the same as its 1090t counterpart

wheres your stability testing?

[FlanK3r]

Titan: yours 4656Mhz is stable?!!!

[Titan7171]

Titan: yours 4656Mhz is stable?!!!

suicide validation only

cpu 4.2ghz nb 3ghz 12 hours prime stable, 3rd place on stable chart........maybe with better cpu 4.3ghz-4.4ghz.

Im waiting to see much better results from better cpu steppings. Hope its not only good for high superpi. There should be a few more people with better stable overclocks than me but it still hasnt show up?

[jacopo1403]

hi all, i need to make a choice what is better i7 920 at 4000mhz or phenom ii x6 1090t at 4000mhz? i have to buy now thx

[crazydiamond]

get x6

[jacopo1403]

why? give me motivations plz thx

[Zeus]

why? give me motivations plz thx

A little reading around this AMD section should do....

How would a Scythe Mugen 2B work with an X6-1055T? I've got an AM2+ board that ought to get a BIOS update soon for Thuban, and $200 for 6 cores seems worthwhile, over $100 for 4 cores and a lot of missing cache.

[Titan7171]

I dont understand......theres no standard here for stability. Theres people on the stable list that only did 1 hour prime this is not really going to help people.

i'll keep you posted on that one.

Prior to May 1st, there was no established standard for stability. I simply trusted people to be both honest and accurate. Someone had mentioned that I should formalize the definition so as to be more meaningful to those interpreting the charts, and I agreed. All new entries from that point (post #56+ / page 3) have proven themselves as stable via 8+ hours of y-cruncher, OCCT, LinX, Prime95, IBT, etc. I have also on occasion accepted reasonable alternatives to that requirement such as a couple days of WCG with no invalid workunits. All new submissions not providing such proof get marked as "untested" until they do even if the poster marked it as stable.

My point is that there is certainly some credibility to the "stable" classification.

@nex_73: I'll need you to run it over night some time (8+ hours). I know it's kind of stiff, but it's just barely enough to provide a reasonable assurance of total stability.

[nex_73]

@Particle: Sure, no problem. Will probably do it tonight anyway...

[p9ing]

In the overclocking chart, some 1055T's have a multi different from 14x. Is this just a typo or something else going on?

[Particle]

Locked chips are allowed to use multipliers lower than their maximum. Seeing some entries like 12x isn't really that weird.

Correction to my post #180:

My stepping is CCBBE CB 1013CPDW, not 1013CDPW.

[INFRNL]

not to clutter this thread, but is the 1090T worth the $100 over the 1055T?
I know you have a better chance of higher clocks, but it seems lie most posting are around the same clocks no matter which chip, performance should be the same at same given clock speed

[richierich]

$100 for less stress on you, your mobo and memory? Sure, why not. The 1055T can clock almost as high; limiting factors being what I've just mentioned .

+1 ..
Its well worth it for the person that isnt so OC friendly with Hardware, Especially if your Hardware isnt up to it too.
(Like NOT HTT Clockable)

[richierich]

y-cruncher is crunchin away

[Particle]

I'm taking this in the opposite direction and seeing how low of a voltage I can run stock at. Ran all night at 1.200V. Trying 1.150V now.
