Thanks @PeterOz Do I the checksum on my Windows 10 or the Dell Optiplex 745 Windows XP Pro?

[PeterOz]

You can use win 10
it is just to confirm the file matches the file at dell - You do have the dell checksum don’t you?
Under the download button > Show details

Okay @PeterOz thanks for the help. It looks like the checksum matches. I have attached the information from the checksum of the file. I hope this helps.

I heard you had to update to this BIOS to upgrade the CPU

From where or from whom

[bryanvader]

I have seen some youtube computer videos where they say you have to have the latest BIOS to upgrade the CPU.

[Bruce]

that can be true, especially if you have an older motherboard and want to upgrade to the newest processor.
but your mobo is an old gen, and the ‘new’ processor you want to install is also a similar vintage - so you may not need the BIOS update.

it all depends of course if the ‘new’ processor is supported by your current BIOS.
quick test is simply to plug in the upgrade and see if the PC boots, if it doesn’t, it’s unsupported and you’ll need the latest BIOS version. or at least a BIOS version higher than the current one, that does support the processor.

Okay @Bruce I will try that. I have not yet bought the CPU yet. I thought I had to update the BIOS first. Does anyone know why this latest BIOS will not update for me? Thanks for the help and sorry to keep bothering you for help.

What anti virus are you running

[PeterOz]

What is the service tag number on the dell

[Bruce]

that Core 2 Duo Q6700 processor came out around the end of 2007.
where are you buying it from?
what is your current processor?

to answer your question as to why it won’t update;
[ul]
[li]incompatible BIOS update with your system[/li][li]file corrupted during download[/li][li]file corrupted on website[/li][li]faulty BIOS chip[/li][/ul]

Thanks for your help. The service tag is 5K5SMC1. I think it has the Intel Core 2. I do not think it has a anti virus installed.

[PeterOz]

The checksum says it is good so should work
Try download from here Click On Me
From what I found (Post #27) I think it should take the cpu with the current BIOS.
The only problem is if you buy the cpu and it does not work you are out of pocket.

May I ask why you are upgrading an old XP machine - just curious

[bryanvader]

Okay @PeterOz thanks for helping. One more thing how should I install the file. Should I do a DOS key or just click on it to install it. I will probably not update the CPU. I got this computer off of ebay for a old XP gaming computer. Thanks for the help again.
