Is my settings "correct" (Opteron 146)


Recommended Posts

Hey All,

 

I have managed to get my Opteron 146 (CABNE 0530) to 2900MHz. My RAM gets capped at 250~260 (or so I think). Is the absolute MAXIMUM that my CPU and RAM can get?

 

I was wondering if you would take a look and see if my settings are correct or know any better settings and values. (RAM and CPU)

 

Here it is:

Please see my system settings in my signature.

 

p.s. This is with out of the box BIOS (6.00 PG - 11/02/2005). Do you think updating my BIOS would make any difference?

 

Thanks in advance.

Thanks! OK, the thing that bogged my mind is that I see Opty144's going over 3.0! (over at OCFORUMs)

 

I don't know, there is something magical about this number "3" that forces me to investigate more! :D

 

What is the maximum vcore that these opterons can tolerate? I tried 1.425 (to reach 3HGz) and it was a no go! :(

 

I am going to try 1.45 tonight! ;)

Yes, I indeed have an Opteron 146, what I was saying is that the "lower" 144 models seem to be able to reach 3.0GHz, and here I am with my 146 hitting 2.9Ghz only (being CABNE 0530 batch and all...)

 

Hopefully upping the vcore might be able to do the trick.

Most 146's I've seen get to 2.7-2.9 without issues.

Gettings them past 3.0 can be a LOT tougher.

And reaching 3GHz vs being Prime stable at 3GHz are two very different things.

Also bet there are more 144s at less than 3G than above 3G :)
