My PC has 6 gig ram
However, every time I restart my PC, and you look at the resource monitor, it shows different total memory amount every time PC is restarted.

Sometimes it only shows 2 gigs, sometimes 4, sometimes 6.

Anyone else ever heard of this issue?

See if you can round up the system components he's using, would be a lot easier if we knew what he's working with.

Can you confirm if this is the motherboard he has? If so, he needs to make sure the memory is installed in the correct slots. I assume he has three memory sticks? If so, what DIMM slots does he have them installed in? Sometimes removing and then reinstalling the memory can help.

Resource monitor shows four different values. Available, Cached, Total, Installed. Which one is fluctuating?

Yes, that is the mobo, and its whatever it was shipped with by alienware is how it was installed.

It is the Total that is fluctuating, which I never heard of before.

Ok, I'd try and reseat the memory and then run a memory tester for starters. He can get a copy of Memtest 86+ from here. If a stick or two of memory is failing it's possible that could be his problem. So have him run Memtest for a couple passes and see if it throws any errors.

Does it show differing values in the BIOS when he restarts? If so, it is very likely improperly seated RAM or bad sticks, as Lv has pointed out.

If you are running it at 1600 or bclk is overclocked then bump QPI/VTT voltage +0.05V and check if it's acting the same ... missing DIMM on X58 was usually caused by too tight timings or too low voltage ( memory or memory controller ).

On 1333 it should run without issues when you are not overclocking anything.

Looking from CPU side memory should be in 2, 4 and 6 slots.

its running at 1333, default timings/voltage. memtest turned up nothing.
