Topic: Overclocking the N280
I know this has been discussed quite a few times in other topics, but i was unable to find the specific answer to what i was looking for.
I have an N10Jh, with a N280, with the FSB at 166 at stock.. but only able to go x10, no x12 is possible on the N280.. as i am sure most here already know.
I have been overclocking my N10Jh over the past few days.. incrementing from 1.66ghz, to 1.7, 1.75, 1.8, 1.85.. stress testing along the way. 12 hours of Prime95 came back with no errors at 1.85ghz (FSB at 185), and the cpu temperature did not hit 70c.. max was 67c, but it seemed to hover around 65c or so most of the time on full load.
Also did some benchmarking with 3dmark06 at 190 (1.9ghz) and it seemed absolutely fine, though i have not had a chance to stress test it with Prime95 overnight yet.
After looking on this site, i have noticed people with the N280 seem to be encountering stability issues very early on.. often around 1.75ghz (fsb 175 x10).. and this has kind of made me want to back off a bit, so i generally just use SetFSBTray as and when i need it for Fallout 3 to go up to 1.75ghz.. but do i really need to be this conservative? I was pretty confident 1.9ghz would have been fine, and possibly could have gone up to 2Ghz..
What i want to know is this: is it essentially stupidity to run this kind of processor at 200 x10 all of the time? Am i risking the longevity/lifespan of the unit, regardless of if the system is stable under 12+ Prime95 hours of testing (and beneath 75c temp of course)?
When i use Prime95, i basically keep everything on default.. i do the 'torture test', then i use 'Blend (tests some of everything, lots of ram tested)', with the default '2' torture test threads running. Am i using Prime95 badly? Is 2 threads, while effective for dual core processors, giving me a very conservative stress test?
Basically my only doubts are about the longevity of running this processor at 185+ FSB, and the chance that i have been using Prime95 badly. I am not an experienced overclocker, as is probably evident, and i sat reading lots of threads on this and other forums before having a go.. would just like some clarification/advice on these two points if possible.
