Hello

I wish to upgrade the cpu in my EI System 2220 (pcworld purchased in 2001). I can not be sure about compatability, so I wondered if anyone would be willing to recommend an upgrade for me.

Here are the details. Thanks in advance.

Hi Gaz.

What you have there is a socket 478 Intel Pentium 4 running at 2.2ghz with a 512kb cache.

This chip is a very old one and isn't made now or actively sold new anymore.

I have seen a 2.8ghz model at www.scan.co.uk for around £50. But it genuinely isn't worth it for the upgrade in speed for this cpu as new intel core2 chips retail from this pricepoint.

You want my honest advice? Save the money you were going to spend on this cpu and put it toward a new system when budget allows.

Thanks Alex

I understand the reasoning.

I saw this on ebuyer:

Intel Pentium 4 Northwood 3.0GHz SKT478 FSB800 512KB Cache

They retail on ebay for about £40 inc p&p

Any thoughts please?

Gary

Same thoughts Gaz.

P4's are simply not worth buying, they never really were to be frank, not as all all-rounder chips. And it your case doubly so because you're only seeing a few hundred mhz upgrade in speed for your £50.
