RE: Precision T3500 error 3 & 4 + loud fan
Thank you for writing to the Dell Community Forum.
Request you to please remove the memory modules from the system, try one memory module at a time in each slot and then test the system. It could be the memory module or the memory slot on the motherboard causing the problem. You can also try these memory modules on another system to test. Memory error has occurred please refer to this link http://dell.to/1gOqfpM.
Please reply if you have any further questions.
