System memory keeps changing

Hey I have a Dell t7400 with 6x2gb ecc ram installed. In the bios it shows all 6 simms installed but says there is 8gb is installed. Every time I boot it says system memory has changed. What is going on?

bad/incompatible/improperly seated dimms most likely

is this a recent development?

Yea it is. Running fine then the windows install decided not to work, so reinstalled over to save files. Now it's slow and always going non responsive, and this error also.

do a memtest

Will do

While booting, it should also tell you which dimms are malfunctioning. If it does, reseat those dimms a couple times, heck, even switch dimms locations.

Sorry I forgot I had this post. I fixed the issue. I pulled all the ram then cleaned it with isopropyl alcohol.
