L2 cache error

[Johnathon Johnson_1]

I have an LH4 that crashes randomly, locks up. Diagnostics tell me L2 cashe is not responding. Can you tell me where L2 cache is? or how to disable long enough to keep users on-line while replacing? Thank you!

L2 cache is on the processor, if you have several processor, take off the wrong one.

Thank you for your reply. I have tried replacing the one processor on the system. Same thing. Everytime I run diagnostic the server locks up while testing "processor/cache". I have disabled internal and external cache with no change. Any suggestions?

hi
try this few things:
look in the hardware event log for recorded problem
try with a new version of diagtools
try upgrade bios to last version
if you have miltiple processor, be sure that all the needed VRM are inserted.

Hi there.
Is it possible, that you have some cache on the board ? If you have several of these chips on the mobo, try to pull them piece by piece and do not forget the jumpersettings or whatever is necessary to activate the new size of onboard cache. I have had this problem on a Gigabyte board. After checking the cache chips i had to replace one. Then it worked again.
