Unknow CPU id consumes more power?

[Gaucho]

Hello,

upon building a new system, the motherboard BIOS reports the CPU (and AMD Athlon 2650 15w) as unknown. This is OK as the motherboard (a Dell C521 one) is old.

The CPU is ADG2650IAV4DP. I was using an old Sempron 3400+ 59W (SDA3400IAA3CW)

My question is: does the system consumes more power if the CPU id is not known? I mean, since it does not know the CPU specs, doesn't it request all it has?

I have the impression that the system can handle CPU usage and power more accordingly if it knows what CPU is it and its details. I'm afraid that, in the end, the system will permanently consume all the 15W of the new CPU but would consume less than that on a regular basis over the old one, which it "knew'.

Please help me understand this. Thanks.

Thanks but I know all of that already.

I just want to know how the system behaves with a non-identified (but working OK) CPU.

There's no way to know how it would behave, but I wouldn't trust it with my data if it is listing valid CPUs as "unknown". It may or may not have problems that may involve permanent data loss.

Frankly, if its that old I have to wonder if you even have 8GB of RAM in that since that is the minimum requirements.

Thanks. By "behave" I mean that all I want to know is the power consumption.

If someone knows it, please let me know.

Regards,

Nobody will know. My guess is your CPU was never officially supported or designed for that board, so you may be doing nasty things like overloading the regulators, trying to use a voltage outside its designed range, etc. I could come up with more examples, but I think you get my point. That's why I say "behave" because power consumption is NOT my concern. I was (and am) more concerned with you using that system and when something breaks it damages the pool in an unrecoverable fashion.

As for power usage, you'd have to go to the motherboard manufacturer. My guess is they have no idea because your CPU and board aren't actually designed for each other.
