RS/6000 7044-170 "44P" memory

#1 (**permalink**) 01-05-2008, 10:21 AM

Hello, I've recently purchased a used IBM RS/6000 7044-170 "44P"
333MHz 1GB Ram, (2) 50GB Disk and AIX 5.3 With Maintenance Level 4
pre-installed. However, doing a 'prtconf' at the system prompt only
shows 512mb of RAM but 1gb is installed:

My question is how do I get the system to recognize the full 1GB RAM?

This looks reasonable, however, one of my 170's also was rather
picky after a memory upgrade. I seem to remember that the banks had to
be filled pairwise with the same type of memory, otherwise
I saw a similar effect. The 170's hardware manual explains the order
in which the banks have to be filled, it's kind of "interleaved" IIRC.

I would do a physical inventory and verify that you have 1GB. I don't
believe you have to do anything special.

You may have been shorted. That memory goes for a premium on the used
market.

cfg says their are 4x256MB, so there's little to argue about.
If system says only 512MB are good, then they are probably in the
wrong order or such. I've seen such weird things before.

Don't think so,
memory for 44P's is pretty abundant and relatively cheap on eBay.

Yea, I physically checked for all the memory to be there. Did noticed
the paring up of "sticks" according to the manual. All 4 256mb stick
are the same part number and manufacture. Had problems with it staying
booted up when it first arrived. FedEx wasn't very kind to it and the
seller did a real crappy job of packaging.

Kept getting a FAN failure error on the front panel pointing to the
CPU fan, but all it was, was a loose connection. I totally
disassembled the box, cleaned it out (was a real dust box) and
reseated everything, and even swapped the memory sticks around. Still
no joy.

Guess I'll play around moving the memory and see what happens.

Thanks

I am corrected. I didn't see the second half of his post (I was choking
on a carmel apple at the time, typing with one hand). I could have
saved some typing if I had read on. :-)

As far as it being cheap, I guess I haven't caught the memory being sold
on eBay. I have a 44p with 512M, and I have been itching to upgrade it.
I just see the exorbitant prices the memory houses want, and the
second-handers don't want much less.

Well, I systematically checked each set of 256kb sticks on boot up
until I found a bad one. Contacted the seller and asked for a
replacement set, and he mailed them yesterday!! Schweet!!
