When I bought my AMD Athlon 2000+ XP in sandra it says my CPU Voltage is 1.84v... but isnt it suppose to be 1.79v? why is mine higher?
 
there can be at least 4 reasons why

1) Sandra's notoriously inaccurate for system monitoring (benchies are ok)
2) Your mobo may be overvolting your cpu (not necessarily uncommon)
3) Your voltage may have been raised in the bios
4) Sandra's notoriously inaccurate for system monitoring :D
 
...most likely:

Your MoBo, like most I've seen, isn't all that accurate when it comes to measuring absolute voltages. They are usually terrifically accurate with relative changes, but usually equally crappy at the absolute value. Example - the system in my sig reports the +12 line at 11.45 volts. My Fluke DVM says it's 12.07. Guess which one I believe...??....:D

Any reason for concern?

Well I havent touched it, it was like this when I bought it, should I lower the voltage or just leave it? Any benefits have a higher voltage?


Sandra 2003 and my BIOS both say its 1.84v, any other way I can test this thats accurate?
 
Is your motherboard an Asus? Mine overvolts by around 0.08V, what setting does it say in the BIOS? If I set mine to 1.775 I get 1.85/1.88
 
if your CPU is being overvolted then i suggest you manually knock it back a notch or two...just so its running in spec...assuming u are not overclocking...it will help to run things a little cooler and probably prolong the life of your CPU for a while...
 
Asus motherboards have a tendancy to overvolt the CPU. Go into the BIOS and set the CPU voltage to 1.75 or 1.725. The processor should run at 1.75 I believe. This should allow you to run closer if not right at the proper voltage for the processor.
 
My mobo is ASUS yes... it says so on my sig....

Ok I went into BIOS and it says the voltage is 1.70 but sandra said its 1.85.

My CPU temp can get as high as 63 C and i just bought a new cpu fan and heatsink.... did nothing, is temp for my processor
(look at sig for specs) average temp or is it way to high?
 
try lowering the voltage to like 1.6ish....it wont hurt to try....in fact i have brought my voltage down to 1.55
 
why do people get unreliable voltage readings? what should you trust....the BIOS, or a program?
 
Make sure the heatsink is clean - if there is dust build up in the fins, you can get really high temp readings.
 
Get Motherboard Monitor 5.

Sandra is terrible about taking readings. I have the Asus A7N8x-Dlx and Sandra likes to report my vcore around 2.4 or something like that. I know I'm not running a vcore anywhere near there. The processor wouldn't handle it, my heatsink would just melt at that and I haven't done any volt mods.

Don't use Sandra to check temps, voltages and stuff like that. It is not accurate.
