I really want to know if the new brisbanes are soldered to IHS.
i bought this new 4000+ that does 2.9GHZ at 1.36V but no matter i cant go higher.
It boots at 3.0, even at 3.15GHz but no matter vhat Vcore its not stable (temps go past 50C mark).
To be honest, i tried 1.48V and im scared to go higher as i dont know how much is too much for 65nm X2.
anyone help?
1.55V is a max. you would want to go with very good air cooling.
Brisbanes are soldered.
I wouldn't go much above 1.5vcore either.
What VCore are most Brisbanes shipping with?

hmmm, probably i will save for water
Best bet is to use a really good water cooling setup.
I used the WC setup in my sig (-the D-tek (I used a TDX) for a 4800+ brisbane and it kept both cores around 4-7*c idle and 12-16*c load in 22*c ambient temp. according to SpeedFan. You can most definately add about 10*c to that for actual temps though!!
more than that. with water cooling, the core temp will never ever ever be below ambient. ever. :p:Quote:

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
physics dictate a different result, as the previous poster alluded too, a regular water setup or righteous air can not cool below ambient......
pelt cooled water setup, maybe.............

Those are just Speedfan figures anyhow. I don't think the issue with Brisbane temps is going to be fixed short of putting a temp probe on the processor itself which is physically impossible due to the pin array and the IHS.
baldy, you say physics. What is the purpose of a fan of any kind? When you turn a box fan on in your house when it is hot, does it not cool you down?
Seriously though, how do we actually know how hot the core REALLY is on the Brisbane? Unless someone has literally put a probe on the core itself and measured it. Is there someone here that can lead me to a link or even some type of physical print that can tell me that the Brisbane core actually runs @ such and such temps? I havn't done that much research on the subject so don't take me wrong (no offense intended), if there is something out there please lead me to it..

P.S. Sry for crapping your thread Mad_Man!!
Stay under 1.55v and you're good.
Lol. 1.6v+ here 24/7 folding on a 3600 brisbane...Quote:

that all about it...
OMFG i was scared at 1.55V at 90nm Windsdor, let alone this 65nm Brisbane...Quote:

That much overvolting for sure shortens the life span of the chip.But thank God for SOI in AMD's chips,it makes them very resistant to maltreatments from us :)
And as for Brisbanes core temps,my calculation for my Brisbane is i need to add 19 or 20 degrees(for 1. and 2. core respectfully) to the temps CoreTemp is reporting in order to get the real temps of the cores.I got this by comparing the core temp at idle and load with CPU temps my MSI core center is reporting at full load and idle as well SpeedFans measurements.Since my ex Orleans was having similar temps reported at load by SPeedFan and CoreCenter i suspect that my idle temp at 1.46V and 2.7Ghz for my 3600+ Brisby is around 7+20 and 9+20 for both cores (CoreTemp reported + 20 degrees C offset) and my full load(OCCT) is 30+20 and 31+20.Cooling is very good HyperTX.
I hope this helps.
Brisbane DTS is broken, you can't rely on what any of the "Core" temperature monitors show.
Hence i said how i calculate my "real" temps.Read up.
"Water and Air will never ever be below Ambient NO, BUT, it CAN be Ambient."
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>.
again, careful what you say, air, nor water, is 100% efficient, there is no way air cooling, or normal water cooling can cool to ambient, a few degrees over, yes. close to ambient, yes.
again, physics 101 prevent this from happening......of course, there are ways of short term cheating:rolleyes: , but the effects don't last long.........
laterz,

Well being I'll only have this chip for a few more months, ( begs for k10 to show), not too worried about it. On a side note I have seriously tortured every Amd cpu I've owned and none of them have died yet. Even my old Duron 600 is still kicking in a friends computer, at 990mhz 1.65v. Close to seven years of abuse on that ole boy...Quote:

I also got an email from a company who was in contact with AMD. AMD responded that the DTS wasn't ready yet. We have all seen that in most cases it works well (pre-Rev G1 chips). But Brisbane doesn't look too good.
I've also put together a new system, and while PC ProbeII reports 22C idle, I get 17C and 8C in Core Temp. And even a bigger difference when running dual Prime95.

I don't get the big variance between Core 0 and Core 1's temp.Quote:

I guess some are better calibrated than others.
My 3600 Brisbane reports 2C and 8C using coretemp
I wish :shocked: :rofl:
Is there proof that AMD is actually starting to solder chips? I have only seen the one case where the guy ruined his fx-60 or something... I'm taking the IHS off this 3600+ of mine so i shall see what happens.Quote:

hmmm, im tempted to do it, i thought that they are soldered...
dont want to ruin it...

do it mad man :D
Do it or your user name will be changed to sane man :DQuote:

me vs ihs: :slash: :ROTF:
well, i cut it all the way with razor blade and tried to pop it off. it was hard stuck there so i thought "what the..." and applied a little bit more force...
It came off with cracking sound and i was scared to hell
lucky me, it was not soldered, just that dried stock thermal goop caused that sound.
She's well and a few degrees colder :D :D
i hope my user name wont be changed lol :ROTF:
no pics?
hey mad man what are you using for hsf on your brisbane? I recycled an xp-120 and its been a pita to get it to seat properly
i use Noctua NH-U12F with two slow fansQuote:

temps went from max 49C to 39C load at 286*10.5@1.44V
any updates...what did you gained???? temps, ocing? :d
well my 7600GT died, it was oced and i think that the Aero forced it to run oced 24/7, not only while gaming, so yesterday it locks in vista and then crashed.
And then artif*ckts appeared during boot... its dead, RIP
so now i have to find a temporary replacement and then ill post some results.
so i have an old 6200LE for now :( at least it drives Vista w/o problems.
anyway by removing the IHS i gained at least 10C on both cores, maybe more. Its real shame to see how bad contact the IHS had with core. Lapping did nothing to temps, but removing ihs >10C
before, she was stable at 2.9Ghz 1.36V and loads at 41C max.
Dont really remember idle temps coz she spent almost all time under 100% orthos load lol, but after boot it was around 30C
3.0stable wasnt possible. Temps shoot past 50C at 1.49Vcore and then Win gave bsod
now im at 3.05Ghz, 1.44Vcore and temps are under 42C load, idle is under 30C
im amazed to see how it helped. I didnt test what vcore it needs now at 2.9Ghz, but to be honest i dont care about 2.9Ghz lol.
Ram is now at 509Mhz, 5-4-5-9 timing, btw, this ram is 333 at 4-4-4-9 default lol.... nicely overclockable...
so i should give it a try ? ;)
in my case it was really worth it...Quote:

Wow, great results on the IHS removal, it is quite tempting, but I guess its not worth the extra 30 bucks or so to buy a new hs to get an extra 100mhz or so.
sometimes 150mhz more IS worth it ;)Quote:

it would be interesting to compare temps of your infinity and my noctua when you remove the IHS...Quote:

very nice results you have here guys :up:
Now I'm thinking about beheading my 65nm 3500+....
Maybe it will let me reach 100% stable 3GHz out from it... (so far 2.88GHz rock solid)

it worked :clap:
That IHS looks convex to hell O_O.
Getting a Brisbane 5000+ Black Edition. Tempted to do it. Not sure if it is soldored. Any ideas?
my standard G1 Brisbane 5000+ isn't so i don't think so..
Brisbane's aren't, see sig.
A amd 6400 would defo be soldered? The temp difference between cores sometimes 10C difference is probs due to crappy IHS!! would be nice if could remove it as my Thermalright 120EX is bolt thru :D
My core temp shows as high as a 20c difference between my 2 cores with IHS OFF so i wouldn't bank on your suspicion.. and yes i've remounted and mounted several times :)
maybe the higher one is the "real" as brisbanes are know to have "bugged" core sensors reporting too low temps.Quote:

with the biostar 7025 t utility and the new bios the temps read correctly
on mine.core temp reads 2c on core 0 and 12c on core 1,t utility reads
36-40c,30 with the ac on.before the bios flash it read in the 50s
My brisbane was not soldered. CAALGQuote:

Looks like I will have some fun next morning , too bad I don't know the temp with my X2 4000+ brisbane .
I Removed IHS but the heatsink didn't touch the cpu core any more , so I put the IHS back with a little super-glue to attach the IHS .

Brisbane X2 4000+ @2.85 / v1.35
Does anyone have any idea if the G2 Brisbane chips are soldered? My G1 isn't and is currently naked, and I am considering either a BE-2400 or a 5000BE as a Christmas present.
i had to scrape a bit off the socket on my s939 system to get the stock heatsink to sit flat after i took the IHS off, do you guys still have that little issue with AM2 chips?
I think that has to do with the OEM manufacturer of the socket, be it foxconn or whoever else. I don't know who manufactures the socket on my board but i don't have any clearance issues with the socket AFAIK
