Is 1.44v too much for 24/7 usage?

[cnumartyr]

While 1.44 volts isn't to much it will significantly shorten your CPU's lifespan. Most CPU's can last about 12 years if left to stock settings. At that voltage you could burn out your CPU in under 4 years. OCing no matter how little your trading higher clocks for lifespan. Upping the voltage from stock really cuts into your lifespan and should never be increased by more than 10%.

You are correct.. but cmon.

Like OCers really keep the same CPU for 12 years... :lol:

 

[Rolenio]

Hell my Pentium 133 MHz is still running as a firewall on someones network.

My Pentium 133@187 worked for 7 or 8 years... CPU is probably still OK

I have a Pentium 60 with the div error in working order thats about 12 years old. OCers keeping a CPU for 12 years most likely not but 6 years likely. The 10% suggestion is important on keeping about half the CPU's lifespan. Going higher really cuts into the lifespan quickly so I strongly suggest not going any higher.

Hafnium may give the Penryn a bit more than 10% but only a major materials changes makes this safe.

Has anybody's Core2duo ever died because of electromigration? It's really rare I'd say...

I would think under 1.5v should be fine

 

[Andrius]

So let's say a C2Q's lifespan is 10 years under stock 2400MHz @ 1.3V
Let's say it works 2400MHz @ 1.07500V and 3000MHz @ 1.24375V.
How long will it last ? My bet would be 4-10 years.

Those old Pentium chips had a ton of material in them (0.25um technology).
They were a lot less likely to die due to electromigration.

While 1.44V is high it is within Intel's spec but I wouldn't want to run my chip on 1.44 anyway. The choice depends greatly on how long you plan to have your CPU (at least 3 years for me).

If you get errors 5 hours into your Prime95 Run you should play around with the RAM Transaction Booster/RAM Performance Enhance.
When set to Extreme (Gigabyte's Transaction Booster with Standard, Turbo, Extreme options) I got errors after 5 hours of Prime95. In a review on anandtech I read that EXTREME was useless when overclocking (I'll try to find it).
While I was only overclocking the CPU the errors where always within the first 90 minutes or not at all.

life span of computer is very short and gets short each year
in july of 2006 the c2d came out
in nov of 2006 the qx67600 came out
in july of 2007 the q6600 go came out
in nov the qx6950 comes out

in `1 year all the above chips will be obsolete the value of the $1300 qx6950 will be around $400 on ebay while a qx6700 may fetch $200

turn your voltage up on low cost cpu's like the q6600 and replace it in 3 years - so the whole discussion is mute.

the fact is the increase in performance is increasing explanationary therefore the required life is dropping in proportion -


THE KEY IS TEMPS - RUN YOUR VOLTAGE SO THE CPU RUNES AT 65C OR LOWER AT MAX OUT PUT! IT WORKS!

Pretty much what I was getting at... By the time my Q6600 dies even if I ran it at 1.6v I could by a better replacement for 200 bucks.

 

[CompuTronix]

I strongly agree with dragonsprayer and cnumartyr. If you do not overvolt more than 10% (Vcore 1.5) and you're diligent about maintaining safe temperatures, then your CPU will die of neglect and old age years before electromigration begins to affect overclock stability. I recommend that you stop agonizing over it; just crank it up and run it. It'll be fine.

Your pretty much correct but not everyone can buy a new CPU, mobo, and RAM every 3 years. The CPU socket changes and your force to buy new atleast those 3 items. The thing here is the drop in lifespan isn't leaner but more of on a segma curve. A small drop in the top OC could add years to your CPU's life. Got to remember these systems are quite useful even after 3 or 4 years.

I like OCing my new PCs for top performance then when its ready to be replace, after 3 or 4 years, I set it to stock and use it for file servers or my sons game server. You can put an old Pentium in the back of your car and use it as an MP3 player.

Don't get me wrong 10% is safe but its about the max I would suggest for the average OC'er. Its not to say the OP's OC to 3.6GHz couldn't be done within that 10% given a +3 bin.

If you are always looking for a gaming rig, a upgrade everything 3 years sounds reasonable

 

[cnumartyr]

Every 3 years is pretty rediculous if you want to game with decent graphics settings.

Mid-range every 2 is more like it.

If you can't afford $1500 for a new rig every 2 years.. don't OC. Infact.. if you can't afford a new rig, don't OC period. You know there are risks involved with OCing, period.

 

[randomizer]

People are so finicky about voltage. Run it at 1.65V+ I say!

If my mobo still worked I'd start pushing 1.8V through my A64 3700 to see if I can get it to 3+GHz stable on air (it's not a good chip).

But seriously, if you aren't running 75C at load, theres really no problem. It will not seriously shorten the lifespan of the CPU, you may lose a year or 2 at the most with 24/7 operation, it is only a small voltage increase.

Also, consider what "normal" full load temps you are getting. TAT may give you 70C, yet running a multi-threaded game may get you to 58-60C. 70C is bad, but unless you bought your PC to run TAT, who cares?

 

[zenmaster]

So long as you are operting within Intel's stated design standards, there is not any risk to your CPU.

They publish both safe temperatures and voltages.
And your 1.44v is well withing that range.

With that voltage and speed, however, you may need good cooling to keep temps in check.

 

[dragonsprayer]

of coarse i am i am mr right (my wife told me that) so i guess i am always right?

wait - i am always right accept for when i am wrong since i say i am wrong then i must be 100% right.

that confirms it - i am 100% right


crank your cpu 1.42-1.45 for most c2d duals and g0 quads - the b3 are another story!

you get a highly repsonsive computer with proper overclocking - 1.6v is a good question why not go up to 1.6v?

answer: you do not need too and there is very little benfit

 

[dragonsprayer]

water: i do not think water makes much of difference - the limit is the thermal compound, the mass of the cpu cooler above the chip

good heat pipes can cool high voltage to almost the same with air as water- in the real world outside of running orthos for fun quad cores do not see that much load. increasing your speed will greatly improve your responsiveness.

I took the position of only building and selling overclock computers in 2003 to prove that it can be done - every system we tune to the sweet spot which is can be found on these fourums.

i think 3.6ghz with quad is pretty sweet

3.7 is nice with an x6800
3.4 for most dual core chips


amd? i don't due wallmart systems so i do not no much - but i was not impressed with the fx-60 overclocking 1 or 2 ago and amd chips are just not nearly as smooth. the sweet spot is 2.6-2.8ghz same as the fx-60


ramble ramble.......

 

[randomizer]

Well the FX-60 was basically teetering at the edge of the K8 architecture limits, so that was expected. You only buy those chips if you want e-peen.

 

[homerdog]

Is 3.6GHz really necessary? What do you do that requires such speed? I'd say drop down to 3.2GHz and find the lowest stable voltage.

But in answer to your question, 1.44V probably won't harm it unless your temps get too high (yours are getting up there at 65C).
