[comp.sys.ibm.pc.hardware] Expected SI of 386DX-25?

elliot@xenna.encore.com (Elliot Mednick) (04/09/91)

I have a no-name 386DX without documentation.  SI (5.0) reports that it is
running at 25Mhz (20Mhz w/out "turbo").  The CPU performance rating
SI gives is 15.8 (12 at 20Mhz).  Isn't this a little low?  Shouldn't it
be around 24? My 286/16 gets 12.3.  Am I putting too much into these numbers?
I bought it at a show, but I have a few weeks to return it if I don't like
it.

Further info:  2MB dips (72x256x1 some -80, some -70, some -60), C&T 
(dated 8810 on the chips), AMI BIOS, XCMOS set for all zero wait states, and
fastest DMA, all shadows are on (main, 2pages video).  Unknown jumper 
selections.

Sys config:
Noname 386DX, no cache, 386DX-16 installed(!), no coprocessor;
2H2F MFM controller w/1.4, 1.2 no hard drive;
Oak VGA (8 bit)
1S1P

Thanks in advance.
-Elliot

I just read that the new version of Norton Utilities SI gives lower
numbers than previous versions. I bet that you're just running 
different versions of Norton Utilities.

Good Luck!
