Stressing Voltage regulators with HLT command

gustavo, this is getting ridiculous. No silicon maker likes to admit errata, and noone "invents" some that don't really exist. Yes this particular one rarely strikes, but it does and this is why it has been documented.

If you want to know which mainboards AMD looked at and found OK (yes they do test voltage regulation quality under maximum stress), have a look at their extensive Recommended Mainboards list. Those that are on the list certainly are OK, when some other board is not, than all this says is that it hasn't been tested - it might be OK as well.

Thanks Peter,

So you are quite sure that the voltage regulators of the Mainboards AMD approved are so well designed to withstand the stress imposed by Disconnecting a 1.4Ghz TBird and changing several times by nanosecond from 1A@1.30V to 70A@1.75V.

You are the expert, I trust you. I am just an agronomist.

 
One further clarification to my meaning regarding the errata being a fake:

AMD would want to avoid recognizing they made an architectural design mistake, that would be worse by far than the errata they declare.

Recognizing an architectural design mistake !!!

Still see it as ridiculous Peter ?
 
Anybody could please dare to answer if it is or is not an architectural design error for AMD to try to keep the Voltage regulators working from and to

- less than 1Amperes @ 1.30Volts when disconnected

- aprox 70 Amperes@ 1.75Volts when @ full load

When you have a TBird 1.4GHz?

I really have not the slightest idea, but I was suggested at another forum that the stress would be excessive, cannot tell if it is true and just am looking for people than could have enough knowledge, if the person who can tell if it is true is not in this forum, does not exist so please come on experts an idea of tolerable limitations you should have...

Thanks Gustavo.-


 
gustavo, now stop it, will you?

First, it's 40 Amperes, not 70. Then, of course there is plenty of choice in voltage regulation solutions designed for the Athlon range of processors. And it's quite easy to verify a mainboard design's voltage regulation quality, we discussed that already.

 
Apologize Peter,

1-The TBird 1.4 GHz consumes 72.1W max not Amperes, my mistake, Amperes = Watts/Volts = 72.1/1.75 = 41.2 Max amperage.-

2-Did not want to bother anybody, just asking to whom I considered could know the answer.-

You have been of great help, thanks again.-
