Passive Opteron anyone??

It is certainly possible, especially as you're managing under 1v on the chip.

I remember a while back on XS someone ran a 3000 without any heatsink, but I can't find the thread right now.

IIRC, It did upto 1.4-1.5ghz with no cooling at all, Not even a heatsink but for stock speeds. It only needed a BGA heatsink and a 40mm fan, I cant find the thread aswell

Dont embed large images - link them.

Heres a quick screenie, gets up to about 42c

Hey Raiky thats not under full load for a few minutes surely!?

That was only for 2 mins, but I can leave it for ~1hour and it goes up to about 42c

Buy a bigger screen, image isnt so large then

Not everyone can afford that.

good point. increase the size of that image, because i cant quite see it on my wall mounted 60" plasma screen :cool:

Both of my screens are perfectly large enough thank you

Stop your girly yellow whinging then :mad:

On topic, just ran OCCT passive and it went up to 46c

I define a large image as something that breaks the forum tables at 1280x1024. Which yours did

lol by a whole 14 pixels

Was actually bigger than I thought oops *shuts up*

whats the song being played in that video im sure i have the album its on but cant rememebr the name

CKY - Flesh into Gear

sorry to the OP for that.

spoonz · 8 Mar 2006 at 17:19

i once ran an athlon 2100 with no heat sink because I was convinced it wasnt making contact.

It started to smoke INSTANTLY as soon as powered on

turned it off, attached cooler, ran rock solid for 2 years

Hard as nails those AMD chips

just out of interest what is the lowest vcore an a64 cpu can run at before it will not post?? surely there is a point at which it will not clock at all, or the mc has not enough juice to function.
say for example you could go as low as 0.4v and it would still manage to clock at 600mhz or so lol
completely pointless I know but I’m still interested

cheers

Mr Mister · 8 Mar 2006 at 22:05

most mobos wont go lower than 0.9v

Hesky82 · 8 Mar 2006 at 22:21

yeah i cant go lower than 0.8v on my dfi mb, have a feeling it will post but not run at all stable at stock speeds

Clint · 9 Mar 2006 at 09:24

Mind you, there has been some indications on that if you are undervolting the CPU to very low volts and at the same time has a high ram voltage you could burn your CPU.

I believe I've seen it over at DFI..can't really remember :rolleyes:

With stock vcore and high bh5 style ram voltage, as with the mem controller beinig on the chip, a % of the ram volts goes through the cpu (as far as i remember)

that is correct, I've only ever seen this happen with excessively hi ram voltages. the difference in vcore voltage is only slight compared to the amount we see some people run these CE6, UTT and BH5 ram sticks.

anyway clint you should know, you undervolting your 146 successfully, heck you were the guy that put the idea in my head and got me experimenting lol so if it goes wrong I'm gonna blame you

na I'm just gonna be running some low voltage generic ram on this htpc system, much the same vdimm I run my uccc sticks at, around 2.5volts

cheers

Before I pulled my 146 out of my system I wanted to see how flexible it was and had a go at undervolting the chip at stock speeds and managed to reduce the voltage to just over 0.9v with it still being prime stable at 2ghz.

screenshots pls?

What is that? Don't you know that when running a passive heatsink it takes hours for the temps to peak, they just keep climbing and climbing.

Haha, well...I did just sell the brother of your FPAW (for a premium price) with the help of both that screenshot with 2.0GHz @ 0.99volts and another with 3.1GHz @ 1.475volts...sure is a amazing performer.
