the original CPU was a 650

I also get an "other failure" according to the boot lights.

Firstly there is an edit button in the top right of your posts (just below the 're:' button of the previous post) which makes it easier to read that posting 3 times in a row 😀

Your problem is possibly due to the new CPU being a Tualatin core. These required lower voltage than the older Coppermine and Katmai cores. So not only does your BIOS need to recognise Tualatins, your motherboard has to electrically support them too.
However, to my knowledge the Tualatins were all Socket 370 processors while the Coppermines were available in both Slot 1 and Socket 370 of speeds up to 1.1GHz.
It's possible to get slot 1 -> socket 370 adapters, and if this is what you have then I'd say your processor is a Tualatin. Some adapters will allow Tualatins to run on older boards - some don't.

Can you post pictures of the processors including any numbers/text that might be on them?

Its also possible that your motherboard simply needs a BIOS update to recognise the newer Coppermine processor.

I Know it needs a bios update now, don't know for sure if that will fix it though. IT SHOULD according to dell. And no it's not a 370 socket adaptor, it's a copermine 1000. I would post pics but It's being ass and won't let me. My bios is Two stages out of date, according to dell the update i download gave support for 1ghz+ cpu's but i need to get some 1.44mb disks to update it. all i have laying around are 360k and 720k disks.

I was able to get my computer to let me post images it might take me a couple posts though. the only stuff on the cards is the speed and build date. the 650 from 99 and the 1000 from 00

Phoenix BIOS lists a 1-4-3-3 error code and the list of codes I have just says 'Autosize cache', nothing more, so at least that's a starting point.

I Found the same thing and looked up "Autosize cache" too. I'm gonna have to update my bios and go from there. I posted this then spent hours searching around myself for an answer.

Is it a 10 x 100MHz or 7.5 x 133MHz cpu? your board may not support the 10x multiplier if it is the former.

PIII 650 only came in Coppermine-core form. So a 1GHz Coppermine should throretically work, however...

I'd go to http://www.cpu-world.com and search the CPU ID on the site by either it's SL number (ie: SL4BR) or ID code (ie: 80526PY1000256) and try to identify if it's a 10x100MHz or 7.5x133MHz FSB chip. A quick search on a Dell forum showed that the T650r may only support a 100MHz FSB chip, so it may not recognize the CPU properly if it's a 133 chip.

In any case, it also may not work without a BIOS update as well, so that may be worth trying first.

It's a 7.5 x 133 and the 650's a 6.5 x 100 I hope the bios update lets it support a 133

Its likely the motherboard does not support 133mhz fsb processors. 650mhz is COMMON as the fastest 100mhz chip you get. 850 is another "fastest possible" chip.

I should be getting some HD disks so ic an test if the update dose what the sparse description says "lets A05 to A07 users upgrade BIOS for faster CPU replacements." All i have is a brand new box of 2DD disks. NOT BIG ENOUGH it says, I thought a 470kb program could fit on a 720kb diskette... But who am I to Judge Dell and there all powerful holy-ness... ...

man there are pentium3 1ghz and 1.1ghz with coppermine core and 100fsb. 😒
its not very easy to find though, i also want one to run on my bx platform.

I meant common speed walls. 600mhz was the fastest first gen p3 made. It came with 512kb of cache. A LOT of systems stopped at 850 mhz. I don't know the details off-hand, but there was a shift in coppermine cache and some boards didn't support it.

Not only that but Dell was also notorious for programming only the strings for the CPUs they want you to upgrade to in the BIOS. For example, systems with that Motherboard may have came with a 650, the fastest they sold in their upgrade store may have been a 750 (just an example), nothing faster will work by design.

Anyway, I work for a PC store that does recycling, I'll keep my eyes peeled for a faster PIII, but can't promise anything.

Yup. My Dell GX1's have this issue. You can only use BIOS versions up to A7 if you want to be able to use the fastest P-III's in them. Anything after that and they hobble your upgrade options to about 600mhz.

Such a policy just motivates unofficial BIOS modifications. My main retro Slot-1 system also uses an unofficial BIOS to support Tualatin core P-III processors.

It also motivates in using standard equipment instead of using Dells.
I personally avoid anything that can't use a standard PSU and a standard AT(X) case.
