Dell Dimension 5150 - What CPU does it even have?

[Harichi]

So I just got this computer. It uses DDR2 RAM (put it in myself!) but it's a Pentium 4, 1 core with hyperthreading and it's 2.8Ghz.

The problem is that, on the Wikipedia article for Pentium 4s,[en.wikipedia.org] there's no 2.8Ghz Pentium 4 that isn't Northwood (PPGA478, DDR and not DDR2 and also has no hyperthreading) and the only 2.8Ghz Pentiums I can find with DDR2 are Pentium Ds which have two cores as opposed to one.

TL;DR: Dell's Dimension 5150's CPU must have a CPU that either is nonexistent or is unique to the PC.

Well you should replace the thermal paste on a PC that old any way so take the cooler off and have a look.

It is probably this one: https://ark.intel.com/products/27447/Intel-Pentium-4-Processor-2_80-GHz-512K-Cache-533-MHz-FSB

I would if I had new thermal paste or if the Dell heatsink wasn't such an arse (thing's huge, Pentium 4 gives off more heat than a nuclear reactor).

It can't be that CPU because the socket is a PPGA478 which only supports DDR (not DDR2), is 32-bit (this is 64-bit) and has no hyperthreading whereas the Pentium 4 in the 5150 does have hyperthreading.

Edit: Also that CPU has a maximum temperature of 70°c. It doesn't reach too far off that when idle. The huge heatsink is entirely needed and it wouldn't change too much after having new thermal paste.

Possible socket LGA 775
But u can run cpu-z or the dell detection www.dell.com/quicktest

It definitely is LGA 775 since it uses DDR2 RAM, but there's no LGA 775 Pentium 4s that are 2.8Ghz.

Well u could use the dell homepage and check the specs with your serial number.

Why are u running around looking online when all u have to do is look in the BIOS.

Problem is that the computer's harddrive wasn't wiped and so the Windows XP installation is passworded (even the hidden Administrator account is passworded, who the hell does that) so I can't run very many programs or even use the internet since it's an unrecognized network.

It could also be a celeron: https://ark.intel.com/products/27119/Intel-Celeron-D-Processor-336-256K-Cache-2_80-GHz-533-MHz-FSB No wait that is LGA


Run CPU-z if possible.

The BIOS just says it's a 2.8Ghz Pentium 4 with 1 core and hyperthreading.

Also you can look up the Dell Service Code on Dell.com/Support to ID the specs better perhaps. As long as those specs shipped out with it originally, the service code would have that info for the original shipped specs.

IIRC, there were 478 Boards that came out that had 2x DDR1 + 2x DDR2 DIMMs and both an AGP and PCIEx16 slots on them; so folks could make such upgrade transitions.

The serial number/ or "service tag number". You can find the number in the bios and is also printed on a label on the bottom(possiblem back) of the system.

Run CPU-z if possible.

Couldn't be. No hyperthreading and less cache. That is the correct FSB though as my 800Mhz DDR2 RAM is underclocked to 533Mhz.

I'll run CPU-Z if I manage to bypass the passwords on the computer or get an installation disc from someone (I threw away two Windows XP discs two months ago, go figure), but the latter could take a while.

I don't have an unused disc and the computer doesn't boot from USB even if I set the correct boot order. If it did boot from USB I'd be reinstalling Windows XP by now.

A password is easily removed.

Not when that requires something I literally can't do.

Then just take off the CPU cooler thermal paste costs $2.
