Wrong ram speed reported in System Profiler...

[OmegaMan]

Here's something interesting.

I have a QS 933, 1024mb ram (256 factory installed, 256mb + 512mb). I'm running OS 10.3.1.

When I go into my system profiler, it shows my ram as PC100. I thought the 10.3.1 update would have fixed that, but it didn't.

I wonder if my system is losing some performance (though it's running faster), or it's just a reporting quirk?

Any else's system saying something similar? (and yes, that's a lot of S words!)

it would be wierd if it were running at the wrong clockspeed. I'd try just leaving the facotry installed stuff in and taking out the other ram you put in...just for testing purposes and see what the system profiler reports. If it is somehow running at 100mhz then yes, you would be loosing some performance.

Hmm, it's PC133, including the factory installed stuff. I've got Micron memory in there now (the other 256 & 512 sticks).

Jaguar always reported the correct speeds...

i would figure it's just an OS issue with your Mac...or the configuration of your mac. I seriously doubt if you didn't change anything hardware wise before the upgrade to 10.3 or had any sort of hardware problems that the speed would just drop :| or run @ half of it's intended speed, heh. But who knows..that is very wierd(i like to spell that word wrong on purpose)

does that machine actually run it as pc133? I know my old powerbook shipped with pc133 ram but was only capable of pc100

I know apple was way behind on adopting high speed ram, dont remember exactly when it was though

The 933MHzhas 3 PC133 slots.
Could just be a problem with the System profiler.

Try removing the 3rd party RAM and leaving only the Apple-supplied RAM in there, and then check to see if ASP reports the correct speed.

Apparently, 10.3 got even MORE pickier about the quality/type of RAM in the machine. I would bet that if you removed your 3rd party RAM that ASP would report PC133... then you might want to contact Micron about that situation and explain to them.

I have the exact same problem with my flat panel iMac. I have 768MB RAM, 256MB came with the computer, the other 512MB I installed myself. Both DIMMs are listed as 'PC100', even before I put my 512MB in. Either there's something wrong with Apple System Profiler (like a bug) or there's something that's making our RAM really run at 100MHz.
