Pin-mod question: System crashes under 17x 1.73 to 2.26 setting

Thread Starter 
I bought an XPS 2 on the boards here a few weeks ago. It has the 1.73mhz Pentium M processor that had been pin-modded. Notebook Hardware Control has been installed and is used to control the system.

It ranges from

6x (.988v) which is 800mhz,
8x
10x
12x
14x (1.244v) 1.73ghz
17x which is 2.26mhz (1.340V).

When the system is limited to 14x speed, everything is fine. However when I allow dynamic switching to take the processor to its full 17x setting (2.26mhz) 3d applications crash minutes after starting them. (Tried Battlefield 1942 and Age of Empires. It happens every time, crashing to the desktop)

This behavior only happens when 17x overclocking is enabled.

So my question is, how can I troubleshoot this issue? Is it the voltage? I'm not sure how voltage works here in relation to the processor, or how to change it.

Please advise.

You cant pin mod a 1.73 - it has a 533 FSB. It must be a 1.7 400 if at 14x, it runs at 2,26.

Well if at 14x and at default volts 3d applications crash, sounds to me that the 1.7 is not stable pin modded.

Download prime95 and see if at full speed, it survives prime testing.

Yes, can you please tell us how u got a 1.73 533MHz to run at 2.26 with a multi of 17 (instead of 14)

Ooops. . . I do have a 1.70mhz, not the 1.73.

It doesn't crash at 14x but at 17x (2.26ghz).

i think you might be in need of some volt modification

How do I know what to change the 17x voltage to? Less or more? can it ruin the cpu ?

You have to ground a pin or two to alter the voltage, and then use a voltage altering program in proportion to what you set the CPU to run at. The thread in which this is explained in is called "Extreme Pin Modding" and it is very well informed and written. It takes some effort to understand some of the procedures but it’s worth it.

If you follow the guide and make sure you arent shorting any pins before you test the config. then the chances of ruining the proc. are very small.

For a second ..yes maybe a few seconds ....you led me believe I could overclock my 1.73 Ghz.

Only if that was true.

Just messing...

Me too. I was dreaming of where my 2.0 would go if I could bump it from 15x to 18x. People read what we want to and ignore the reality of the world--or what is actually on the page.

Here's the thread on it, just read the charts and it should be pretty easy to do. If you have any questions feel free to ask . The fact that your CPU boots stably at 2.26GHz usually signifies that you shouldnt need much more voltage
