H all,
I undervolt my E6600 @ 2.4Ghz from stock 1.325V to 1.020V with temperature @ 44C full-load with room ambient @ 30C (CPU stress test with orthos > 2hr in progress w/o any error yet); Super PI gave me no impact on the performance. Btw, will undervolt cause any harm to the CPU or other components? Thks in advance~ This post has been edited by sotong168: Sep 10 2007, 01:35 PM Attached thumbnail(s)

QUOTE(nate_nightroad @ Sep 10 2007, 01:36 PM) tat is underclocking...main advantages is to save power comsumption...i do it too... i don think there is any harm to the processor  QUOTE(slash @ Sep 10 2007, 01:39 PM) underclock = lower than default speeds. @nate_nightroad, as slash mentioned, it is undervolt not underclock and thus i suppose there is no impact on the performance, mind to tell your setup?undervolt = lower than default voltages Added on September 10, 2007, 1:44 pm QUOTE(sniper69 @ Sep 10 2007, 01:42 PM)  , used to do it on my Venice E6, instead of 1.4, i use 1.2vCore, damn i love the temp even on stock heatsink, well that's the old story eh...  anyway, there's nothing wrong with undervolting/underclocking, it's just lead to unstable system due to low voltage supplied  , correct me if i'm wrong...

QUOTE(mengsuan @ Sep 11 2007, 09:33 AM) My system have to be rock stable since I do folding@home. If it's unstable, folding will fail. I recommend running 2 instances of Prime95 to test for undervolting stablity. any differences if i running orthos instead of 2x prime5 as i suppose orthos = prime95 x2.just now tried 0.88V, the system passed POST but failed to boot-in windows  |

QUOTE(gary_cheah85 @ Sep 13 2007, 05:21 PM) undervolting recommended for laptop? i've undervolt mine around 15% using NHC - dynamic switching. now my voltage is same with sonoma LV processor. i'm using sonoma 1.86GHz , 533MHz FSB yes, i undervolted my T7200 as well and the outcome is impressive, really cooling down a lot than what i expected (i posted the setting & outcome mths ago). crash on battery? could it be just a coincidence?there was once the laptop crash while on battery, other wise on AC no problems what so ever. already stress test while on AC for 6 hours, no problem. how to stress test on battery? |

if both cpu remain at stock vcore but one is OC (the other one stays at stock clock), will both still have the same temperature and power consumption? thks~

QUOTE(5564321 @ Sep 21 2007, 06:57 PM) Sorry for my noob question, can I undervolt the proc like e2140 and in the same time overclock the proc? yes, undervolt & oc gradually and test the stability with orthosSince the e21xx series got is a good oc proc, undervolt it and overclock a bit of speed, is it possible?? QUOTE(5564321 @ Sep 21 2007, 07:05 PM) Another question,will it be cooler and save more powers? i suppose that is the purpose of undervolt  |

◎toda6866, RokXIII & kmarc are right, the temp shud not be that "furious" even at stock vcore, hsf & clock, how do u get the readings? is yours es? what about bios readings?

hi guys, just some update on my undervolted e6600, pairing it with g92 8800gts, during playing cm:dirt, the game hang occasionally, so i increase a bit from 1.020V to 1.075V (stock is 1.325V), the hang issue solved
