i don't understand last week needed 1.7vcore for 2.3ghz now only 1.625 for 2.3ghz can someone explain?

[MiExStacY]

so this morning i thought hey what the heck lets try to lower the vcore and i started lowering it to 1.67vcore and oh it went thru prime95 for 1hr stable.then 1.650 and again stable for 1hr. and now @1.625 for the last 5hrs of prime95 stable.is there a explanation for this

Had you tested it those voltages before?

Chances are it would work @ defualt voltage.. Never know till you try...

 

[MiExStacY]

yes i've tested those voltages when i first got the cpu.i also tested 1.6 before i tested 1.625 but computer froze during prime95

 

[bjc112]

Really?

What about timings, Vdiimm anything that could have affected many other stablity factors?

It got burned in! Actually I don't believe in that 'breaking in' stuff but people seem to do it all the time... weird.

try running p95 for more than 1 hour. Try it for at least 12 hours, for instance. If it can pass that then it *should* be 100% stable.

It's good you don't because burn in is not effective what so ever.

I've noticed some similar things with mine... runs stable at 1.65 @ 2.2 Ghz... but at 1.675 it fails Prime95 @ 2.2 Ghz... odd.

While there is no truth that the silicon burns in (and will overclock better), the Thermal Interface Material (probably AS3) can change. Maybe this week it had time to "melt" better and fill in the grooves in the heatsink.

Or... maybe last week it was a little hotter in your room.

There are a lot of variables that can change from week to week.

not true... burning in does change some properties about the chip itself... do a google search, I'm too lazy, there was an article written about it. while it does not make night and day differences, it definetely does change the properties of the transistors themselves. actually, the settling in of as3 has NOTHING to do with being able to run at lower voltages. the silicon decides that. good luck finding the info, and if anyone seriously doubts me, I guess I can look this stuff up myself.

no memory timings has change.still 7-3-2-2 2.6v

well this week has been the hottest week in minnesota this year so couldn't be the weather.and i'm in the basement so no AC down here.whatever it is i'm pretty satisfied.i don't really believe in that burn stuff cause i've done this to other cpu's before and they never ended up like this.but cheer's to my dltt3c 1800+

While it is true that you can search the 'net and find an article that will support any theory, that doesn't mean the theory is true.

pm wrote an excellent FAQ about this very subject... Does "burn-in" really help overclocking?

And if you still are unsure, just listen to common sense... If "burning-in" the cpu made it go faster, don't you think Intel and AMD would just do that at the factory level, so that they could release faster cpu's?

Here's an excellent forum thread about "burn-in"... Burn-in and "CPU conditioning"
