3700+ San Diego Core Speed

[nheather]

I'm experienting with overclocking my Athlon64 3700+ SD.

I started with

250x11 (2.75GHz) with RAM on 196MHz (333 Divider)

I then tried this, to get the RAM speed higher

270x10 (2.7GHz) with RAM on 225MHz (333 Divider)

Both of these are stable.

I then decided to concentrate on CPU speed and currently have

265x11 (2.915GHz) with RAM on 208MHz (333 Divider)

This can run windows all day, but will lock up on really heavy games

So far I have been on stock volts (or so I thought) so I thought I'd start increasing the volts.

This is where I became a little surprised.

I thought stock volts is 1.4V for this CPU. The CPU voltage is set to auto. But all my monitoring tools agree that voltage is around 1.5V although it varies slightly.

What is going on?

Is the stock volts 1.4V or not?

Or is the motherboard (A8N-E) somehow sensing the need to increase the voltage and setting it to 1.5V?

N.B. Just thought of something to try - perhaps the MoBo just reports high - just going to manually set the volts to 1.4V to see what readings I get.

Cheers,

Yep, just manually set it to 1.4V and my monitors say 1.4V.

So perhaps my CPU doesn't clock as well as I thought as I beleived I was on stock volts but in fact I was on 1.5V.

How high can the volatge be pushed on these CPUs?

Cheers,
