Mac Os For Intel Atom N450


How-To Geek Forums / Windows 7

The Intel Atom is Intel's line of low-power, low-cost and low-performance x86 and x86-64 microprocessors.Atom, with codenames of Silverthorne and Diamondville, was first announced on March 2, 2008. For Nettop and Netbook Atom Microprocessors after Diamondville, the memory and graphics controller are moved from the northbridge to the CPU. This explains the drastically increased transistor. The Intel Atom N450 is a small and cheap entry level CPU for Netbooks and small laptops.In the package is an integrated memory controller for DDR2 main memory and the GMA 3150 graphics card.

Speeding up a NETBOOK with Atom N450 Processor

I have a netbook that came with a Intel Atom N450 1.66Hz 1.67GHz processor. It had 1gb of memory which I upgraded to 2gb (the max) and it recognizes the 2 GB. It is slow to respond to about everything.

The Windows 7 starter experience gives it a 4.7 out of 5 on the Memory Calculations per sec, but the Processor Calculations per second experience is 2.3 out of 5.

I sthere anything I can do to speed this netbook up?

Thanks in advance. Dorothy

Dorothy, apart from the usual housekeeping (minimize startup programs, defrag the disk when over 10% fragmented, etc.) there is only one radical cure and that is to switch the disk for an SSD. That will cost you around $150 to $200, but it would make a BIG difference. If you are interested, let me know and I tell you the steps and the optimal choices.

There is nothing you can do with the procesor. It is a slow single core because of battery life and heat limits. A faster processor would have meant much shorter battery life and a lot more heat. And that is incompatible with the small box. The SSD also uses a LOT less battery than the disk you have and it produces no heat at all - unlike the spinning disks.

But next year things will get better. Then Windows8 supports ARM processors which will be ideal for the netbooks and they are a LOT faster. Those are the processsors they have in the tablets a la Apple iPad and Motorola Xoom - also in the readers a la Nook Color.

Internet connection could be slow which gives the appearance of the over-all machine being slow.

Remember that applications such as Office, etc. do not require a speedy processor.

I imagine Win7 is not configured properly for a speedy interface.

The reply from WHS seems to hit the mark - you can't have a long battery life and a fast processor (yet). The starter edition of Win7 seems particularly slow. You may get a small speed advantage by increasing the page file to 4GB (it won't increase automatically when you upgrade to 2GB RAM) and also by allocating 4GB of a USB key for 'ready boot'.
My hard disc scores 5.9 out of 7.9 under “Performance information and tools” and I'd be interested to know from WHS how changing to a SSD would speed up things.
There is an alternative easy way to speed up your netbook - switch to Linux. You'll be amazed how quickly it boots and shuts down. You can run Ubuntu parallel with Win7 and it will do just about everything Windows can do. You use Firefox, Open Office, VLC media player, Autokey etc instead of the Windows equivalents. It's very easy to set up and use, and does not keep asking annoying questions about whether you're sure you want to do this or that.
Best of luck, kaspin

kaspin, the 5.9 WEI is the highest you can get with a spinning disk. An SSD will give you 7.6 at least. Boot times will be below 20 seconds and programs will show up immediately when called. You have to know that the access time on an SSD is 150 times faster than on a HDD (0.1ms versus 15ms). In adition the SSD used practically no power (longer battery life) and it produces no heat.

Thanks whs - I didn't realise they were that fast. On the other hand, as my processor speed is rated at only 2.3, this will presumably be the bottleneck in the system so I may not see much speed benefit from the faster SSD. On the other hand, the heat/power/unbreakable qualities are important, so I'll start saving up for one.......kaspin

In most common operations the CPU is not the bottleneck - it is the access time to the disk that makes the difference. This is, of course, different if you do e.g. video encoding, CAD type work or heavy computing. That does not mean that your system will become a super performer with an SSD, but it will get a significant boost.

When you are ready to buy the SSD, post back so that I can give you some advice which device to buy (and always on sale which is frequent e.g. at Newegg). In the meantime you may want to read this little SSD migration guide I have made: http://www.sevenforums.com/tutorials/149969-ssd-install-transfer-operating-system.html

You also need to know whether your current disk is 2.5' or 1.8' - the latter is rare but some netbooks were using them. The SSD has to be the same form factor. And the amount of GBs you want (check what you are using now). I use 90GB SSDs on my laptops. You can always offload large files to an external disk (of which you should have one anyhow for imaging) or a large USB stick (16GB sticks come for $15.95).

Thanks again whs for such a comprehensive reply, and also your clear and interesting SSD migration guide. In a couple of months or so I should be able to afford a sufficiently large SSD and will certainly take up your kind offer to advise on my specific requirements nearer the time.

OK, we'll see you in a couple of months. When you make the posting then, put 'SSD' into the titla because I always look at those. After 5 SSDs, I learned a few tricks.

This page is a list of patched kernels for OS X. You are encouraged to add any missing information to help make this list complete! Please only add kernel-CPU combinations you or someone else have tested; don't just add a a CPU or kernel because it exists.

Two types of patches exist: binary and source. A binary patch (binpatch) is used when the target CPU is completely compatible with the stock mach_kernel, but its CPUID is not whitelisted (i.e. Intel Atom). Source patches are used for CPUs such as AMD, legacy Intel, or VIA that differ significantly from supported CPUs—these might need instruction set emulators, for example. Certain Apple programs do not work correctly with source patched kernels.[clarify]
