unlocking cores is it safe?

[Sasori]

He means that it is better to buy and use an aftermarket cooler...

why? il ask again stock cooler is not enuf?

[Sasori]

*double post*

[manbat]

-_-

coz maybe ang stock cooler is design to take on 2 cores and not 4 cores? running 4 cores meaning mas init cguro.

[swiftkillu]

THat's what aftermarket coolers are meant for...para wagtang init...and MUCH better than stock.

putting something out of spec is never safe, not even underclocking (if safe = stability). this is why you compensate by stress-testing (Prime95, OCCT, IntelBurnTest, etc.) so you'll know if the unlocked cores are up to the task when they are needed for intensive use.

quoted for truth (QFT):

the official line is: The cores are DISABLED for a reason: THEY FAILED FACTORY TESTS...some of which are defects in the silicon substrate, problems running at full frequency or a bug introduce during manufacturing...

what they don't tell you is that it is more financially sound to disable cores & sell them at the lower segment than just throwing them out...

for AMD...the best ones become quad-cores, while the rest w/ defects becomes X3's, X2's

for Intel...the dual cores w/ defective core becomes Celeron single core or the Core Solo series...for its quadcore lines they do not because they do not use a true quadcore design...its actually 2 dual core chips in one substrate...disabling core would hurt its performance...Intel's true quadcore design starts w/ the Core i7...

another example:

intel makes a wolfdale processor (45nm core 2 duo). the highest clockspeed within intel's electrical specification becomes E8600. the succeeding dice that doesn't meet the high requirement becomes E8500, E8400, and so and so forth. furthermore, processors where L2 caches are found defective are disabled and becomes the E7xxx series, and further down pa gyud, becomes the E5xxx series. as for the features like SSE 4.1, VT-x or AES is up to intel's discretion kung asa ug kinsa ang target markets.

now im satisfied.. no offense to other replies.

to add to the above tests mentioned by poldo...the BEST test on how good are those re-enabled cores are is by running Virtualization software...if AMD-V runs w/out hiccups then those cores are good to go...

one word of caution lang...if you are one of those rare & very unlucky few who happens to get a processor where the VCC of the disabled core was inadvertently connected to GND during the etching process, thus making the core defective(& thus was disabled) and you re-enable it...PATAY !!!

panagsa nlng ko mka kita mo post si master simoko pero sulit sad kaaug mge replies.

i agree with you on that bai..

1st of all, stock cooler that comes with the processor is not advisable.

so this only applies to unlocking cores kay it sounds general gud?

@ isaacrobot & ethzneuron: pagka-atots gyud ninyo oist ...sigi nalang kog lurk diri kai daghan na akong infractions...

for overclockers and enthusiasts and now for unlockers
