Lenovo CPU upgrade

poop a lot of poop

 

Check if your chipset supports core duo CPUs. I don't think that it does.

 

I believe the notebook has an Intel 945 chipset. That means, it supports both the 533 MHz and 667 MHz. There is no need to change any setting when you upgrade, because the chipset will automatically alter its FSB speed to suit the processor.

But first, make sure that the notebook supports the processor. You are correct about the pin compatibility, but you may require a BIOS update for the processor to work correctly. Check on the Lenovo's website for a BIOS update which supports the processor. Normally, the latest BIOS supports the processors.

 

oh it does. Lenovo sells the same model with the fancier CPUs. The cpu shows up as a Yonah core solo in CPU z. The chipset is 945 express. I am most concerned about FSB however.

 

Thanks, and that is an awful thing someone did to that poor MBZ IMHO!

 

If it has a 945 series chipset you should not have any problems.

 

Levono might have updated the motherboard. If you have a Pentium M or earlier CPU, it will not work even though it has the same number of pins. The layout of the pins changed when they introduced Yonah.

You can download and run CPU-Z, which will tell you the chipset that you have.

 

its a yonah based cpu according to CPUZ. It even comes up as a "core solo". Intel really ought to be more distinct with its product names.

 

The Celeron is based on the Yonah core, but it has half the cache, and a smaller FSB. Intel named it Celeron to keep in theme with their naming system, which has got a little confusing, but is still understandable. They use the left over chips, that failed becoming Core Duo's because of defective cache and a defective core, and then brand them as single cored Celerons. Its a good little trick, because they can make some money from those otherwise wasted processors.

 

well I am tempted to think you are right about the fsb autosensing. Now the question is, which chip? Of course I will wait a little bit until the quad cores get more market penetration. Not to mention Intels new 45nm fab process chips. Both of these should drive the price down own plain ole core 2 duos. Honestly The performance of my celeron 420 isnt that shabby. I only miss it when I am doing something that involves multiple apps. Stuff my dual core opteron desktop never has a problem with. From what I have seen the TDP is the same for a celeron 400 series as it is for a core 2 duo mobile.
Any place better to buy chips than newegg btw?

 

NEwegg has low prices on most of their items, and mobile processors are normally very expensive anyway. Try some online price comparison websites, as they can bring up some good deals. I would also wait for Intel to release their Santa Rosa platform, and then wait a little longer until the prices are lower. Thats the best way to go if you want a cheaper processor.

 

According to PC wiz the memory interface is dual channel. So I'll see how much faster she gets with another 512 in there. Then I'll try the 7200rpm drive upgrade, and I am sure by then, prices will be much more, amenable.
