Highest voltage on air?

Xplo · 17 Mar 2006 at 11:24

quick question please people

Whats the max voltage i should goto with air cooling on my athlon xp?

Thanks for any replys.

Depends on how good your air cooling is. 1.8 - 1.9v.

Its an Akasa copper based cooler (rated for xp 3400) and a 32cfm fan.

So will it be ok to run 1.85v constant? Its an xp 1700, wanna get to 2200.

Temperature is the bigger issue. 55c load max. lower with higher clocks.

gonna jumo in on this thread to but relate it to opty's, safe highest volts for a 144 and how much life does it suck out of them running them on high volts ?

Xplo · 17 Mar 2006 at 12:09

Ok so if i cann keep say below 50 degrees at load 1.85v is fine?

Xplo · 17 Mar 2006 at 12:09

Yeah thats another point how much life will be sucked out my athlon, will it be ok at 1.85v for atleast 2 years?

weescott · 17 Mar 2006 at 12:17

Not sure about life span. But it will be shortened. How much to a specific chip is anyones guess.

Opty' max volts is 1.7 IIRC

1.55 for dual core's according to AMD.

1.7 under phase, I would put any more than 1.6v through an opty on air.

Xplo · 17 Mar 2006 at 12:31

Thanks for replies so far just to sum up, ill be ok at 1.85v aslong as my temps under load dont exceed 50?

none, mine ran perfectly for 3years at 1.85v 2.4ghz just try to keep it below 60c

Dreadi · 17 Mar 2006 at 14:31

yeah cheers, i wonna push more outta my opty 2.9/3.0 ghz

I beg to differ with chopchop.

This question can't be answered, but if the answer truly was none at all, AMD would have supplied these chips running at higher clock speeds with higher voltages.

Chances are that you'll be fine, however you'll be running the CPU out of spec (quite a long way out of spec), so it could at worst case fail instantly, but then it could easily last for 5 more years.

1.85 is well within amd's tolerance limit of ~2.1v, temp limit is about 90c, but while overclocking needs to be below 60c else it can get unstable.
as for amd bringing out faster ones with higher voltages: higher voltage = more heat and faster = even more heat. oem computers would fry.
for an extra 200mhz its not worth the bother for them.
