haha, normal lar, so long already.. the processor asking you to buy new cheaper and more powerful counterpart already...

I think OC will makes writing errors right?

It is not likely to be a CPU related, as normally the CPU is the most reliable part of the system.

Had a problem like this a couple of years back, have to throttle down OC until the system died one day. Root cause? Motherboard. At that time I changed the board to an Abit one and the CPU went flying again.

Especially motherboards manufactured before the dawn of the solid capacitor age. It could be any components on the board, actually, that is more likely that is unable to cope with the increased stressed of overclocking.

The number one suspect for flaky/failing system > 1 year is the motherboard. Just look at the number of chips, conductive pathways, passive components and solder joint on it. Anyone goes, thats it.

coz your stock voltage on Vmch is already pumped to around 1.40+V... my ip35e defaults at 1.23V on Vmch..

haha too bad for u guys.

my system is still good, except my old Gigabyte-965P-DS3 crap out after a year. i was running +0.3 vMCH and vFSB, 457MHz FSB @ 24/7

that experience a good indication for what other ppl stated about the electromigration and lifespan of an overclocked system.

so always spare some money on ur pocket after your system is 1 year old++

p/s: my P35-DS3 requires NO additional voltage for 450MHz++ FSB/MCH

I think it's best is to OC only when you need it. Not like you gonna need it on the games since it relies a lot more on the GPU these days.

I also think this will increase the life time of your PC if you don't 24/7 with an overclocked PC.

Another factor is the electronic components will degrade overtime, not just the processor.

1.83 - 2.00 ghz
i dun think you need to increase any voltage,

That's true.
And sadly, that's the downside of having smaller die processors.

Right now, we're at 45nm, just imagine what would've happen when 32nm and even smaller dies were to be produced.

It seems that E8400s can go far without voltage increase...I think it is better, hope nehalem can go even further....

ElectroMigration is happening in my system now.
Normally i only need to use 1.3625Volts for my Q6600 B3 to run at 400 X 9.
Lately, the system is going through a lot of BSOD.
Had to increase the VCore from 1.3625Volts to 1.3655Volts to stabilize the system.

After increasing the VCore from 1.3625Volts to 1.3655Volts, no more BSOD.

Damn!
ElectroMigration is happening as we speak.
I'm telling people about ElectroMigration, Whereas it's happening in my own system.

LOL Wut?

Nayy, when there's a will, there's a way.
When the time comes, there will be a way for us to overclock them for sure.

then the smaller the Vcore needed to pump for higher speeds... well, hmm, thats why i prefer 65nms.. 32nm procs dont even use FSB, they use QPI and hmm its a mod version of Hyper Transport.. no idea how we are going to overclock when they is no fsb to play with.

Shawts, looks like they saw what we ocers are doing with their procs, so they have locked all the goodies..

the smaller the chip size go, eg 65nm, 45nm, the more electromigration occurs

hmm yeah, electron migration affects anything electronic.. just that at what degree of severity its at, depends on how much voltage ur going to pump into it. So for someone who does extreme overclocking over a period of time, his/her rate of em, would be higher than someone with a least amount of oc or none good stuff to learn more about shawts. I also need to learn more from my sifus too

i heard tht few months ago from my electronics lecturer... but didnt go understand more... just rougly know wat electromigration is... the smaller the chip size go, eg 65nm, 45nm, the more electromigration occurs i think when oc'ed and applied higher voltages, if i not memorize wrongly... but i think company like intel will use better silicon and new technologies to overcome such problem..

a1098113, that's not entirely true.
Even the slightest increase on voltage will degrade the processor. Although it takes time, it will degrade slowly.

As what my sifu told me:
Electromigration degrades the fine copper wires inside microprocessors
Even a normal processor running at it's normal voltage has a degree of electromigration, it's just that the degree is so small it's considered useless to count.

agree with shawty, even stock voltage there were electromigration... ur proc will die no matter if u OC or not in the long term... eg 10, 20 years... but i guess most of us who OC will change proc every 2-4 years... so its doesnt matter if u have mild OC... i have 2 amd proc now running as BT rig and home rig on stock which i have been oc it before when i was using it as main rig...

bro theres nothing wrong playing with voltage as long you know where the limit is and u dont go overboard with it like some ppl

well i dont totally agree with neocz. there is of course a degradation to your solid state inside your processor but most of your processors under stringest testings before its sold in the market. And i dont really think TS oc voltage is high enough to promote electron migration with total effect. It can be other issues

I don't know. I dont play with voltage. And will never play with it.
