Another option is to take all the memory out, and then put one module at a time back onto the motherboard, and test that with memtest86+. Should be on the install CD/DVD. Once you have identified a memory module that tests without errors, try that in each of the other slots if possible. If there are no errors in any of the other slots, then you will need to test the other memory modules in a slot you know works OK, to see if it's one of the other memory modules that is faulty. It's also possible to have high density memory and low density memory that works and tests OK individually on a motherboard. However when high density and low density modules are mixed together at the same time in a system, then you might find errors occuring. I had this on a Centos 5.5 32 bit system, and it was very frustrating to locate the cause of the error. Testing one individual memory module at a time takes the guesswork out of which module may be the faulty one. But NEVER mix HD and LD modules together, as they don't always work well together.

Re: [CentOS] Strange Kernel Warning.
Thank you john, I surely hope that shifting RAM around would fix the issue...this board is extremely expensive to change...about 2K the board along. >>> John Doe 8/17/2011 8:54 AM >>> From: Lisandro Grullon >Can someone give me clues as to whether my memory is going bad or I am having >problem with the actual board. Thank you in advace. Any led on the motherboard (even better if next to a RAM slot)? Usually, the best (if you can) is to swap RAM modules. If the error follows the RAM module; it is a module problem. If the error stays at the same position, it is the motherboard.
