Atom N450 Overclocking Adventures! (CPUz vaildation)

[SpikeP]

before i start, there is no extreme cooling method here. please mods move this if needed.

I recently purchased a MSI Wind U130 cause my laptop died and i wanted something to tide me over. Also this is running the new Atom N450 CPU. I looked around after purchase and found no one who has pushed this new chip, so thought i would go adventure myself. See what it has got!

First thing was to open the machine itself, fit a 1gb DDR2 module in so i could have 2GB memory. Next was to find the PLL chip on the other side of the PCB. This reads:

ICS 9LPRS113AKLF



From here i found that setFSB had that one in it's library of clock generators. First hurdle was at just 7fsb higher, i was getting lock ups.

I then discovered there is a link between this and the pci-e clock, so for reference, here is the superpi 1M time on stock with 2GB of memory



And here is my result so far. the key limiting factor again being the pci-e frequency but also adjusting the PLL N and PLL M is making a impact as well



And finally to verify that i am legit, here is a CPUz validation as well

Hope you like the results. Not mind blowing i know, but this is all cooled on the stock cooler and just two ram-sinks stuck on top. Netbook is still fully screwed shut and no signs of changes!

Oh, and any tips on things to push further will be appreciated. I think some Hexidecimal editing will be in order, so long as everything works with that as well.

Okay. I ddn't think anyone would want any more info, but it seems when people are searching N450 overclocking, i come up top, lol

In the post above, you have the ICS chip you need to know. In SetFSB you will need to increase the PCI-e as well as the FSB, otherwise it locks up very early.

I used the following

210 FSB
127.5MHz PCI-E

Now i also use 2GB of ram in my netbook, so the embedded 1GB and a seperate 1GB stick. Above this i can get it to get a screen, but nothing stressful.

And to a couple of emails, yes. This was doen on the stock volts. I looked into the voltmods, then i remembered it's a Atom and decided against it.

Well hope that clears up some questions. Anymore, please post and i will see what i can do - Paul

This is the clock speed I can get with barely any difference in temperature and very very stable





Viva La Revolución!

Hello there, iv tried setting the FSB through setFSB but nothing worked, it either freezes or gets s PLL error, or doesnt change the clock speed at all
i have a HP Mini 210 with the intel Atom N450 1.66 Ghz
can anyone help?
