Hello all, been a while...
I have a 333mhz xlr8 G3 processor with the 1 meg backside cache
settable by the processor, etc. I bought it in 2000. I put it in
my 8500 that I used for years- definitely faster than the stock 132
MHz. Since I received my 9500 and put the 8500 back into stockish
condition and have them running side by side I note serious
differences- the 9500, with the Xlr8, is seriously crash-prone
versus the 8500, with the stock 604 at 132 MHz. The 9500 will crash
several times a day during hard use (ResEditing, working on my TC
for Nova, etc), and even during normal use (web browsing, checking
mail, etc)- these symptoms were also exhibited by the 8500 when it
had that processor installed. The 8500, on the other hand, with the
132 MHz 604 processor, has been up the entire time since it has had
that processor installed- over a month now with no hard crashes,
freezes etc. Netscape has crashed a few times but has not brought
down the computer.
Could this be caused by processor overheating? The Xlr8 will idle
at 43-47 degrees Celsius, going up to 51 degrees when the computer
is actually doing something. The backside cache, supposedly able to
run at 222 MHz according to Xlr8, has to be set down to a much lower
setting to prevent additional crashes. When I first got the card I
broke one of the clips that hold the heat sink on, and although it
stays on by the clips and on the processor fine, it has not much of
the grease that is supposed to be in there to help conduct heat away
from the processor. Is this the problem? Is there something that I
can do about this? My old Sonnet G3 used to run between 25-31
degrees Celsius so I really suspect the problem is overheating.
Ideas? Any would be helpful.
I have to ask, how do you know how much grease is in the mount? If
you have disassembled it and reassembled it, you needed to clean all
of the grease off and apply a new coat. If you took it apart and
simply put it back together again, you ended up with an air pocket
between the heat sink and the CPU, which acts as an insulator.
Breaking one of the clips also causes problems because the heat sink
is not held on uniformly, causing additional cooling issues. I
don't know the xlr8 cards, so can not advise on the best way to work
around the broken clip. As to setting the cache speed down, that
was something that needed to be rectified when the card was new and
under warranty. It could be symptoms of overheating or bad cache
memory. At this point, without physical access to the card, any
diagnosis would be impractical.
