Currently at 2.6GHz @ 1.65v 3000+ E3 Venice, safe?

It's fine to be honest.

All these women on the forum, OMG IT GOES OVER 49 DEGREES!!!!!!!!!!

I don't recall AMD saying that it was a very bad thing to have your temps over 50 degrees. I've got a newcastle chip myself, with a stock voltage of 1.55-1.6, i can't remember. Anyway, i'm running at 1.72v with 2.5ghz clock.

That's on air, and my temps get into the mid 50's.

I've had the chip over a year, been at these temps/clocks constatntly and its still running as good as new.

diferent cores... i.e you have increased yours by 0.125 and he has increased his by 0.25v over stock. Twice as much... were saying lower it by 0.05 which is still more than you. Whose the woman now?

The thermal limit varies between cores,

As a comparison the limit is 63*c on a Sledgehammer 130n core (fx55) according to Amd specs

Take note of the voltage, that's on AIR cooling.

Not me

I dont expect that to last long and its not yours so your still the woman

(only joking btw

Haha, i've only had it like that for a short period, just whilst i was benching 3dmark

Damn the x1800's benching abilities

Nice score though

8300 on my 7800GT so far

It's the voltage adjustment feature that gives them these massive clocks, that 700mhz is a 200mhz overclock on the memory :eek:

, but saying that i've upped the voltage on them a fair bit

But my cards got the 1.2v bug on the core unfortunately, so i don't think i can go much further on the core

also i think you have to take into account any voltage 'spikes' that occur with anything electrical. i dont know how much they would spike but if it pushes it over the edge then bang.

Im not a hardcore electronic techy - but I think all the voltage regulators and capacitors handle voltage spikes (probably handled in both the PSU and on the motherboard) - but er yeah.... they couldnt just have raw "rough" voltage going to something like the cpu.
But er yeah... defo agree with you on the voltage range you have allowed yourself and the reasoning behind it

I cant push mine past 2.43 with mem divider at 166mhz...if i have 100mhz mem devider i get 2.52 but only 147mhz off my memory...this is on 1.55v...i cant figure out what else to do to make it work

Dirk · 14 Jan 2006 at 10:22

Is this a safe voltage for 24/7 use?

Simple answer. Can you afford to replace the CPU if it goes wrong?

You've reached the point of diminishing returns where you need a relatively big voltage bump for a small speed increase. Either improve your cooling, stop where you are or roll the dice.

m3csl2004 · 14 Jan 2006 at 11:29

tbh mate it seems safe enought to me, how you guys can say that its fine on water but imminent death on air is beyond me because his temps are fine.

and if you read xs, youd know everyone uses bit t's

no deltas there

do ask yourself though, do i really need 80mhz more?

1.4v stock.

I can run at 2.52Ghz at 1.53v 100% stable, I just want a tad more, but it seems to need volts to so it

have you actually benched the difference between these 2 speeds/vcore setups? if you feel that extra 80mhz is worth it then stick with it....

i've tested my dothan at these speeds....

2.6, 200x13, 1.40v <<current settings
2.64, 220x12, 1.45v
2.73, 210x13, 1.575v

as you can see i've had to shove an extra 0.175v through my chip for 130mhz. the difference in benchies is minimal. can i tell the differerence when playing games? nope.

is it worth it? most definitely not imho.

OMG, 1.84v just to get to 2.55ghz. I've a newcastle 3500+ and i'm on 1.58v at 2.65ghz. btw 1.5 is stock volts for a newcastle. If i stick 1.62v though it, it takes me to 2.8ghz but my cheapo memory lets me down. Point being surely they don't need that many volts though it, im suprised its not fried by now especially on air.

If their temps are fine, what cooler are they using?

I want one
