3700+ diego.. 1.35 or 1.40 voltage.. what's it mean?

[Vesper8]

hello. I just noticed that the voltage for the 3700+ san diego comes in two flavors

1.35 and 1.40

just wondering if this implies two different models of the chip.. or it means that the CPU can be run at both voltages (or any between I assume) ?

if so.. then this is for overclocking purposes only? and by default it is at 1.35?

enlighten me please

Stock voltage for them is either 1.35 or 1.4v, doesnt make any diff really.

Probably doesn't mean anything overclocking-wise, but the 1.35vcore chips are likely from more recent batches(maturing 90nm process etc).

At stock speeds, it should draw less power and run cooler at 1.35v than 1.40v

All things equal I'd definitely recommend a 1.35vcore chip to anyone that asked. I haven't heard anything about variable voltage requirements within the San Diego Core. Where did you see this?

Generally, lower voltages = more overclocking headroom = better

From AMD's site it seems that there is a normal E4 3700 with the same voltage range as the other single cores (1.35-1.4V) and an E6 3700 (default voltage is a fixed 1.35V, there isn't any range unlike most of the other rev E CPUs) that's probably a dual core Toledo with one core disabled. I don't know which one would overclock better.

It seems I have one of those then...

ADA3700DKA5CF

CCBWE 0544 SPMW

and its 1.35 v...

Should I try an OC or return it and go find one with a known stepping??
