I'm trying to run another app on my shop 'puter...

Its an HP D530 P4 with 512 memory. Lots more specs he
http://h18000.www1.hp.com/products/q.../11632_na.html

When it boots it says DDR 266 and runs up to 512 on the memory test. I
pulled the stick and all it says is DDR 266, no other labels.

On New Egg, this is the closest I can find:

Will this work? Do different size sticks work together?

This is a good place to check, and sometimes to buy:

Those are high, I would check second-hand computer dealers for better prices
on used RAM. Supposedly memory should be matched for better performance,
though I've read that the improvement may be hard to see. I haven't seen a
problem mixing speeds and sizes. Faster memory will run at the speed of the
slowest stick or the bus speed. For example this PC has a 1G and a 512M
stick of PC2-5300 which would operate at 333MHz if on a faster bus, in here
they run at 266MHz.

These are good info tools to show you the hardware details.
