That's the link guys, can you make sense please ?

That's an 800MHz FSB chip. You'll need a new motherboard to run it.

 

[Justintime]

800FSB cpu, not compatiable. So its running at 12x133Mhz, lowest multiplier and highest bus speed.

 

[Simon_89]

What's the maximum FSB processor the motherboard will accept? It was only £2 so I'm not too fussed it wouldn't run

 

[MagicBoy]

Difficult to tell as QDI have disappeared and their model numbers were a bit opaque at the best of times. You would probably need a BIOS update for later model CPUs which would be no longer available from a trusted source.

I'd look for a 2.6Ghz 400FSB Pentium 4.
Try this search in eBay : (SL6SB,SL6GU,SL6HB)

You can run a 533Mhz FSB CPU

That may work. Very good chance but is it worth 16 quid to try.. dunno. Did they make a Northwood 2.8 533 with HT?

He could try overclocking the bus speed to 200mhz and see if it works.

If he bought the CPU "Justintime" reccomended and it didn't work then he could DSR it.

 

[Simon_89]

What is DSR?

 

[MagicBoy]

Distance Selling Regulations. Not sure it applies to eBay though, and you'd have to pay for the return postage.

 

[Justintime]

Distance selling rules, you can return it within a certain period if not happy.

Very true, most 845 boards i clocked did 166MHz with no problem, 200 might be a stretch Guessing the RAM is probably PC2100 at best as well..

Not 100% sure on normal domestic Ebay users but if its a registered business then yes.

CPU for 4 pounds, wow... thats a bargain.

I think it does.

It says it at the bottom of the page.

But the item has to be Buy it now.

I've found a site that has the latest version of the BIOS for the motherboard. How do i find out my current version as CPUID was showing (v1.X)?

So if you guys are saying my motherboard only supports up to a 533Mhz FSB then this CPU should be fine then?

[Justintime]

Yes it should be fine Cpuid should give you the BIOS version in the mainboard tab.

Am i correct in saying that all 478 laptop CPUs are the same as desktop?

There is a 3.2GHz 478 Laptop CPU with 1MB Cache and 533mhz bus for £7.40

It may work, but its a Prescott cpu.. and at that fairly high clock with his motherboard being an older one to say the least.. the poor things VRMs might get fried with the power draw.. i've fixed numerous dead boards (i.e new board and Northwood mobile replacement) on quite a few of those large desktop replacement laptops with those 538 cpus. Another issue is that the clock speed might be problematic as it'll default to a 12x or 14x multi all over again with no way to change the ratio.

For the life of me i can't remember if those ratios were software changeable, i'm thinking not, had enough difficulties yrs ago getting one to work in a MSI 865PE board muchless an older one like that i think i had to run it at 2.8Ghz with an FSB overclock.
