Hi there, what is your thought about this oc, should i reduce vcore even if my temps are normal ?

 

[ZealotKi11er]

If I remember correctly its was ~ 1.35v for Nehalem. I used 1.33v for my i7 920 to get 4.4GHz back in the day.

I recall people going to 1.4V if the temps were under good control (less than 80 at all times under linpack or similar) although there was a lot of controversy about what was actually safe. I think ZealotKi11er's 1.35v is a very reasonable and sane limit.

 

[xKnightx]

so you suggest reducing vcore under 1,35 ?

 

[esp42089]

If you are uncomfortable with it. 1.45v with stable temps and operation is probably fine. I ran my 980x at 1.4v for years. The motherboard ram controller broke but the processor was still fine after 5ish years.

Reducing multiplier to 19x i get 3.4ghz with even less temps almost below 72 degrees, Is better that or to reduce vcore?

 

[MrTOOSHORT]

1.45v is the upper limit for these tank cpus.

 

[xKnightx]

in bios at 1,55 the indication change colour, so is this the limit?

You do not need that much voltage for that kind of OC.

You want to run the lower voltage possible that still gives you stability. If those maximum temperatures were under load, you should be fine. I don't remember how sensitive Nehalem processors are, but Westmere didn't like uncore voltage over 1.35V. That killed more processors than core voltage.

 

[xKnightx]

Which voltage do u reccomend for vcore and uncore qpi for 3.8ghz running 24/7?

 

[mrgnex]

To be honest, with the price of these chips I'd run them on whatever voltage I could cool

 

[Shiftstealth]

I mean, at this point in time are you really concerned with how much longer it lasts? It is already like 8 years old? I can't imagine you should be concerned about degradation this late in the game. In 2 more years phones will be faster than it. Honestly, i'd let it ride at that voltage now.

 

[chessmyantidrug]

I wouldn't run that processor at any voltage. I would get a 6-core Westmere and enjoy a cheap upgrade.

Lowest that is stable, no need for more

 

[xKnightx]

I dropped vcore at 1,232 and the temps on each core dropped almost 10 degrees.

Honestly? These CPU's are on the edge of being worthless (I see them go for around e15-25) so I wouldn't really care about Vcore, they are also extremely hard to degrade/kill. Just watch the temps and OC at as high as you want.

I ran dual X5670's (SR2!) on 4.4GHz somewhere around 1.4V. Nothing wrong happened to them.
