Dell Optiplex 745 BIOS update error message Program Payload Error

[bryanvader]

I have a Dell Optiplex 745 with Windows XP Pro Service Pack 3 with four gigs of RAM. I am trying to update it to the latest BIOS update 2.6.6 on Dells website.
I keep getting this error message Program Payload Error. I was able to update the BIOS before this one fine. I think it is 2.6.4 The Service Tag is 5K5SMC1. Thanks for any help you can give me.

Hello

This is what i found on the Dell site.. https://www.dell.com/community/Optip...r/td-p/8228253

Thanks for the help. I guess I cannot update to the latest BIOS then.

looks like Dell aren’t making the current BIOS compatible with your 15 year old (?) Optiplex.

[bryanvader]

Okay but why is that BIOS update on the Dell Optiplex 745 download page. I have seen videos of people downloading and updating that computer. I want to update the cpu in that computer.

[Bruce]

no idea, might be a question best answered on the Dell support page?
maybe file corruption, have you tried redownloading it?

[bryanvader]

Okay thanks for the help. I did found this on Dell support page.

[bryanvader]

I contacted Dell support. They said the board is probably not compatible with that BIOS. I should update the cpu to Q6600 and to use the BSEL mod to bump to 3.0.

[Bruce]

sounds like a plan.
do yo already have the Q6600 processor ready to install?

[bryanvader]

Okay and no I do not have the Q6600 processor yet.

[Bruce]

shall we close this for now until you get the processor?

[bryanvader]

Yes, you can go ahead close this. Thanks for the help.
