I have E7500 at 2.93ghz then i overclock to 3.5ghz, i have a cheap motherboard so i can't set the multiplier, can sumone tell me if this is a good voltage for at that clock speed?........Base on CPU-Z, my idle speed is 1.9ghz with 1.088V, and Full speed 3.5ghz at 1.256V, im a little bit new to overclocking, so can someone tell me if this is a good voltage for that speed? not too high and not too low, i want this to last for another 2 years.....If u need anymore PC specs u can ask me.

I think its more important to know what kind of temps your getting at full load. That will effect the lifetime of your cpu more. Have you tried to minimize you voltage by dropping it by one tick and testing for stability and so on?

idk how to set my voltage for cpu..i can only find for NB and SB, also it's still cold in where i live, so my idle temp is ~35 C and full load is 60 C~ with Other CPU warming up stress test i get like 65-70 C running for like 2 or 3 hours.

E7500 is bad thing to OC if you have low end mobo (cause its multiplier is 11x) that don't have memory multiplier configs,,,,
you will need FSB around 350 for only 3.85 ghz,,, so if you have low speed ram it will run out of its limit causeing the Oc to fail,,

one more thing intel only allows changing of multiplyers (above the maximum multiplyer ie 11 for 7500) in extreme edition parts like i7 990x ,, x denotes this,,, and in K seris CPU's like i5 2500 K,,,

Hi, I have too an E7500 at 3.95 Ghz with stock voltage, air cooling, but in my case the motherboard is Formula Maximus II.If you want to get the very best of this processor you have to buy another motherboard.The voltage range for v-core are 1.2875--1.3875,
and for Cpu pll 1.55--1.65.I suggest you to increase to the max, and try to get 1:1 ratio between FSB and DRAM.

Actually, that is not quite true. The G41-ES2L supports several different memory multipliers. And low speed RAM? You have that problem no matter what motherboard you use. Because DDR2-800 RAM is virtually standard today, it will give you plenty of OC headroom.

First of all, the E7500, like most Intel chips, has a locked internal multiplier. That's why everything past X11 does not work.

Second, the G31/G41 chipset is an economy, entry level chipset. Unless you get really lucky, you will not be able to push the FSB freq past about 360 MHz. I have a G'byte G41 board. FSB freq of 352 MHz works. 353 MHz doesn't.

This should be your first stop.

Next stop should be a guide for your particular motherboard. Google is your friend.

Go through the guides. Then take your core voltage off Auto and set your memory voltage to factory recommended values. Change the System Memory Multiplier (or whatever your BIOS calls it) from AUTO to 2.00 or the lowest possible value. Then when you increase the FSB, the memory clock will rise in in proportion with it. At an FSB of 266 MHz, your memory clock should be at 533 MHz. Warning: many of the newer G41 boards do not have a 2.0 mem mult.

That G41 board I mentioned up above? I have an E6500 (same basic chip as yours except smaller cache) running at 3.66 GHz (333 X 11) with a mediocre by today's standards ACF7P cooler. It is stable at 3.87 GHz, but the extra performance isn't needed. That same chip runs past 4 GHz in my old EP35-DS3P.
