r4000+stick of 1GB SODIMM PC-3200 Corsair?

Anyone run a single stick of 1 GB SODIMM (400) PC-3200 Corsair (VS1GSDS400) in a R4000 with good results? I'd like a Gb now with the option to add more later.

Also, Zipzoomfly and MonarchComputer are both selling for $126 shipped, anybody recommend one site or the other? thanks

Is the system select better? And if the memory doesn't work out are there companies that will take returns?

What kind of problems would I see with the power draw, less battery life? This notebook will almost always be plugged in plus I have the twelve cell. But I do have the Athlon 64 2.0. I think I'm going to get a spare battery also.

Thanks for the responses. At least, from what I gather, the stick should work and will probably run at 400. So unless I find out otherwise or that I will be experiencing problems other than a short battery life I plan on going with the system select 1 Gb pc3200.

Thanks for the help. The stock Ram is 333mhz which is why I'll be pulling it out. It's off the Corsair forums for me. I hope they actually know if the stick I want is compatable and don't just use their compatability search database. That database shows that only pc2700 system select is compatible.

This is the response I got from house of help:

"I would not suggest it. Please look up your system on our memory configurator and use the module thats suggested for your system."

I thought this was a crappy answer. The individual made no attempt to find my answer, just defaulted to his "safety net" memory configurater which only has three system select sticks total to choose from..give me a break.

So I'm back here with the true believers.

Here is the latest BIOS update:
WinFlash Utility for HP Notebook System BIOS - Windows-Based
Release Date: 2005-07-26 Version: F.17
Description:
This package contains the WinFlash utility and a System BIOS image for the listed notebook models and operating systems. The WinFlash utility is used to locally flash the System BIOS (ROM) on notebooks operating in a Microsoft Windows environment.
Fixes:
Improving system speed while booting and under DOS mode.
Support new AMD K8 reversion CPUs.
Fixing intermittent issue with system cannot recongnize some of HP USB keyboard while resuming from hibernation or rebooting.

I see no memory fixing BIOS updates, so it appears I am screwed. I think I now have to choose between 2X512 pc3200 for $104, (which PastKev has proven works based on his sig. This of course contradicts the insufficiant memory configurater at Corsair, those lazy chumps,) for a total of 1gb pc3200,

or

I can grab a 1gb pc2700 for $126 to go with the stock pc2700 256mb stick in there already, for a total of 1.256gb of pc 2700.

Since the prices are close enough for me, which would perform better the 1gb pc3200 or the 1.256gb pc2700? And just for fun how would 2gb of pc2700 perform against the first two options? I don't know if applications make much of a difference but I imagine the most taxing I'll use is a video editing program.
