Lock-ups with Powerleap PL-iP3/T

[Malcolm Edwards]

Hi

I have just installed a PL-iP3/T with a Celeron 1.4GHz CPU on my P2B (Rev
1.02). I have updated my bios to 1014-3. I have 512MB of crucial PC133
memory and am running Win XP.

At first the system seemed to run fine but now I keep experiencing system
lock-ups. I have changed the FSB jumper from Auto (Default) to 100MHz and
the Core voltage from 1.550-1.575v (Default) to 1.600v - 1.625v (as per the
manual). I still get lock ups.

I have also noticed that when I boot up my system, when the counter runs up
the number of bytes of memory (when it does the memory check) it stops a few
times in the process, whereas as before it used to do the check in one
smooth run.

I have also changed the CAS Latency from 2 (by SPD) to 3.

I am still getting the lock-ups.

Does anyone have any suggestions??

Thanks.

Malcolm.

Can you give us the part numbers on the memory ? How many chips
are on each DIMM and how many DIMMs are you using ?

As for the core voltage, I thought you couldn't change it on a
Powerleap. If they have dip switches or jumpers, are you certain
they are set correctly ? I also thought the monitor chip on the
motherboard could not read the voltage on the Powerleap, because
Vcore is disconnected from the rest of the motherboard.

Has the memory been tested with the previous processor ?

Powerleap's Rev. 2.0 adapters have voltage jumpers, the older versions
didn't. You are correct regarding voltage monitoring - the Powerleap
tells the motherboard it's a 2.1V CPU, so that's what the monitor chip
reports.

I suspect the Powerleap manual suggests setting the voltage jumpers up a
notch if you have problems because their VRM output tends to be a little
lower than nominal according to my DMM.

A couple of things to try:

- Remove the Powerleap, clean any dust out of the fan and heatsink,
check that you have good contact between CPU and heatsink and a *thin*
layer of thermal compound. Reinstall, ensuring the adapter locks into
the retention mechanism and the CPU fan spins freely. This should
address the possibility of CPU overheating and/or the adapter not
seating properly in the CPU slot.

- Ensure you have a dedicated feed from the power supply to the
Powerleap, i.e no disk drives etc. on the Powerleap's power feed.

- Run memtest86 overnight to test your memory. Set it to run all tests,
not just the default standard tests. Test 11 seems to be particularly
good at finding problems on upgraded P2B systems.

If none of the above helps, I'd suggest trying another power supply next.
