How harmful is long-term 1.5v vcore to a C2D when core temps are reasonable?

post #1 of 46
Thread Starter 
Hi folks,

I'm setting up a dedicated folding rig out of mostly leftover parts and a new e6420. It's orthos stable @3200mhz (8x400) with 1.46v vcore and @3350mhz (8x419)with 1.5v vcore.

The difference in folding speed is significant: It cuts about 1 min off each 5000 steps folding a P2609 WU compared to 3200mhz. I think the improvement is due to both the increased speed and the increased bandwidth since I'm running the memory at 1:1 linked.

Core temps when folding at 3350mhz never go above 42c which is pretty good IMO. But how hard will it be on the processor to fold 24/7 at 1.5v vcore for months on end even if the core temps are reasonable?

Elwood

You will be all set with 1.5 vcore. The long term effects will be minimal, and only shorten the 10+ year life span by 2-3 at most.

Thats a lil high Vcore since the top from intel is 1.325. Well like its said it will shorted the life a bit but you probably will not be using that after this long..

Thanks for the answers guys.
Guess I'll just keep an eye on the temps, keep the dust blown out of the cooler and run theout of it.

1.5 is nothing if the temps are good. I've seen VCORE as high as 1.675. So what if it only lasts 5 years. Who's going to be using a C2D in 5 years anyway?

Just like the obsession with 1:1 memory ratios, the whole VCORE thing is a techno-myth. Just ignore it. If you are orthos stable and temps are within acceptable range, you are GTG.

I'm working on testing a >1.5v on a e6600, 1:1 linked synced on evga 680i, 400x9=3600 mhz.

So this thread is pertinent to me. Is 1:1 NOT all that and a bag of ****? Why not? My temps vary with the weather, but when I get into the school year (autumn) they shouldnt scare me as much.

1:1 is bad? >1.5 isnt bad? Share wisom please.

How did you arrive at that conclusion?

MCH is a bigger risk to increase than Vcore or so it would see--but running at 1.5 is well beyond the intedned operational parameters and will decrease the overall stability. When people imagine lifespan they think--oh all of a sudden it goes poof--but what happens is your OC becomes a little quirk--random freezes--the occasional failure to boot or a lock up or a BSOD that only happens every so often--then more often then finally no matter how much voltage you pound it with it does not OC at all and then finally it becomes unstable at stock and then finally it shows up on Bay

Except for the eBay part I know that story intimately.

over 1.5 is way too hot isnt it? it gets hot
with even only 1.4315vcore.
