As you can see from my sig I have a Sony Vaio PC. From what all i read it seems that this PC is unable to be overclocked, due to locked bios or processor. However I was wondering if I could put a new CPU in it. The motherboard is a ASUS P4B266-LM. It is an OEM board but it seems very similar to the other P4B266 boards on the ASUS site. I used WCPUID to check a few things and heres what it says....

Internal clock is 1816 mhz
system clock is 100.9 mhz
system bus is 403.59 mhz
multiplier is 18x
mpga 478 socket

Would i be able to put any Pentium 478 socket processor w/ a 400mhz or lower FSB into this motherboard. For example ive seen a 2.8ghz celeron w/ 400mhz FSB for less than $130 . I dont have a lot of money to upgrade at the moment, but I am looking for something fairly cheap that will hold me over for maybe 6 months or so.

One more thing, what is the difference between a Intel P4 and an Intel Celeron?

Thanks

Overclocking a manufacturered (OEM) system can be tricky as they usually limit the motherboard's bios to very simplistic options, and in a lot of cases don't allow for altering of the CPU multiplier or FSB speeds in order to prevent customers from damaging their systems and voiding their warranties. If you purchase a new CPU that probably won't resolve the issue as the bios itself will still be limited in it's ability to change the CPU multiplier and FSB speeds. As for flashing the bios with another non OEM motherboard's bios that's similar I don't exactly know, if there are ANY differences it could render your motherboard inoperative. I'm not trying to be negative, but overclocking an OEM system is usually a no no so to speak -- unless anyone has any other advice to offer.

As for the difference in-between a P4 and a Celeron it's the onboard cache. The Celeron only has 128KB of L2 cache where the P4s have 512KB (at least) of L2 cache therefore making them faster (and more expensive).

Thanks for the info........The reason i wanted a new CPU was I gave up on attempting to overclock this one. If i get a new CPU i was not wanting to overclock it, I just wondered if it would fit into my existing motherboard to give me an upgrade. I could go from 1.8 to something around 2.5 - 2.8 for fairly cheap. I would assume since its a 478 motherboard and a 400mhz FSB i could put any processor that meets those specifications into my MB. Since its an OEM board i didnt know if that made a difference in what processor would fit in it or not.

i would just give up on that sony vaio. the only thing i'd do to it would probably just add more RAM to it. the highest CPU i'd put in it if i could find it would be any p4 w/a 400Mhz FSB.

[Jitter]

Im not sure what im going to do yet I would definitely like another sitck or RAM. I can put a new genuine intel P4 2.8 400 FSB for like $150, maybe if i shop around enough i can find something used.

Hi jitter, i got the same mobo. someone gave it to me with the processor.
i got a P4 2.0Ghz in it and wonder what is the max processor.
theres not much info on sony's website.

[Geminiwave]

you can add a new CPU. to what degree, I'm not sure...but you can.

definatly the 2.8ghz 400mhzFSB is a good idea I'd say. Try it out.

[Jitter]

yeah i talked to sony before about upgrading they said to talk to ASUS, and ASUS said to talk to Sony. Obviously Sony doesnt want you messing w/ their default stuff, and ASUS doesnt support it because it was an OEM board specifically for Sony. I think you can get a 2.8 Intel for about $150 and a 2.8 Celeron for (it was either $115 or $130). Its a standard socket and you cant change the FSB so i dont see why you cant put the max (2.8ghz) in it. I only play games at 1024x768 or even 800x600 (depending on the game) so i dont need some super computer at the moment.

[benjam|n]

thanks guys
will see what i do
thats why, I will never buy a
everything's done not to be able to upgrade it
the only pb I got with it, is an hardware monitor error at startup (pretty annoying for my linux box : debian)
in fact, it does not detect my psu fan and i have a nice N/A instead of RPMS. i cant disable it, I have to type F1 to continue booting

Well when i got this PC i upgraded from a 486/66mhz PC, and I did not know anything at all about newer PC's. I am lucky I got one w/ an AGP slot or i would of been screwed. Next time I will definitely build my own so i can upgrade easier/overclock if i want to.

[Geminiwave]

wow I thought my upgrade was serious business.

333mhz AMD-K6-2 and a Voodoo 3 2000 PCI tooooooooooooo

Athlon XP 2800+(overclocked of course) and a Radeon 9800PRO

thats some upgrade there :-D Its awesome though...I literally encode mpeg2 files 100 times faster on the new computer.

[Jitter]

Do you encode from AVI to MPEG2? I did that a few times on this PC on medium quality and it still took hours I cant imagine doing it on a slow PC.

[Geminiwave]

AVI, OGG, WMV, mpeg, you name it. ahh High-def stuff too. high res and quality. It took me about 3 hours for 85 minutes worth of video.
