[rescue] Sun Netra T1125

[Mike Spooner]

I presume that it might be possible to get a 480 to run at close to that by
reprogramming the UPA speed in OBP, same as can be done on Ultra-10 and
Ultra-30. I've sucessfully run a nominally 440MHz CPU in the Ultra-10 at
472MHz (118MHz UPA) with no errors. The SMCC UPA data-buffer chips were
specced for upto 120MHz operation, although very few actually could reach
quite that far - the Ultra-4 used best-binned ones.

Hi

I think that the 480Mhz are 450 only, the 420 only supported the 450Mhz as
per
the T1125/Ultra 60. The 450 supported the 250, 300, 400 and 480Mhz from
memory.

Never tried the 480Mhz in an Ultra 60, normally mixing the CPUs does not
work,
but obviously does in this case, but suspect that you will only get 450Mhz
out
of it.

guessing the CPU is the issue.

(501-5729)...have not found anything to indicate that thats a supported
configuration. All I can find is that it is supported for Enterprise 450,
420R...I note that OBP reports as 450Mhz CPU. Anyone have any insight? Anyone
got a spare they would be willing to part with? Is it an OS level issue
similar to that in the following
