| 583406 | 2007-08-21 08:01:00 | Hello I have two computers, both fairly old, which I want to swap the CPUs in - the newer CPU into the older mobo (because one has a bigger case and I don't want to swap the whole mobo). They are both socket 478, but Everest tells me (right beside the socket number) that the older one is "0Eh" and the newer one "0Fh". The older mobo is 400MHz FSB while the newer one is 800MHz. The older CPU is 1.8GHz and the newer one 2.8GHz. Also, the newer processor is some sort of dual core, I believe, because it shows up in Everest and task manager as two processors. Would this swap work (would the CPUs work if swapped)? Would it be worth it? Would there be a noticable performance loss because I would now have a slower fsb? Thanks for your help! |

| 583407 | 2007-08-21 08:14:00 | If they are fairly old, then your 2.8GHz CPU is not dual core, but an HTT CPU. If your older mobo only supports 400MHz FSB, I don't think you can run your 2.8GHz CPU on it. |

| 583408 | 2007-08-21 08:28:00 | check for a bios update - a bios update made my motherboard compatible with 333mhz (AMD - equivalent intel FSBs are higher) when it originally only supported 266mhz. | Greven (91) | ||
| 583409 | 2007-08-21 11:38:00 | Yes, I think qazwsxokmijn (however you pronounce that) is right, it is a P4 and probably just has HTT... so much for dual core :( How do I find what fsb the bios is "compatible" with? The older computer is a Compaq Evo D510 CMT, and has the latest bios update, but everest (my only source of information on the matter) says: FSB Properties: Width = 64 bit ; Real Clock = 100MHz(QDR) Effective Clock = 400MHz ; Bandwidth = 3200MB/s It also has properties for "Memory Bus" and "Chipset Bus". |

| 583410 | 2007-08-21 11:49:00 | Yup cant say I've heard of dual cores having 478 pins. Would have been nice tho. You would have to look on the Compaq mobo to see whats etched on it. See what the brand/model of the mobo is. Even tho it says Compaq on the outside, it doesnt mean the mobo is a Compaq as well. |

| 583411 | 2007-08-21 12:20:00 | The mobo says compaq on it too! Looked around but didn't see much else that looked like a brand/number. | Bob_the_lob (10622) | ||
| 583412 | 2007-08-21 12:31:00 | Is this it ? (h18000.www1.hp.com) If it is, then no it wont take a 800 fsb CPU. Only 400 and 533. This site screws up in FF. It doesnt show the pics but it does in IE. |

| 583413 | 2007-08-22 07:43:00 | Yes, that's the one. Aww, well good to know this before I tried to switch the CPUs over. I'll just have to swap the whole motherboard sometime. Thanks for the help! :thumbs: Edit: PS: The site seems to show fine in my FF... exactly the same as IE except for FF's harsher/less-fuzzy fonts, and also less ads ;) |

| 583414 | 2007-08-22 11:16:00 | yer it did show the diagrams in FF the first time I found the link. But when I clicked on the link again it brought up the text not the diagrams. The same thing happened on the Herald site, often it used to show the main page of the site in the middle of the screen. I think after a while FF gets corrupted somehow and screws sites up. It happened in the latest version as well as the previous version. I've uninstalled FF now, it started to get annoying and gone back to opera. |
