memory upgrade problem.

[argyllandy]

i have upgraded my memory from 4gb to 8 gb . i am running a 64 bit system but my pc is saying it has 8gb ram but only has 3.9gb usable. anyone have any ideas, i have reseated the memory and my cpu with no change.

Try seeing if some of it has been partitioned off for other applications or check if it is being used as a RAM disk or as a cache for applications to store.

Well that doesn't show what your running WHEN you took that pic. If you got 4GB of programs, add ons, tray stuff, viruses, malware, etc. all running in the background YEAAH only 3.9 is 'usable' because your using up the rest of your RAM doing things.

it says 4195mb reserved but why is this , i only put the extra 4gb memory in 10 days ago. can someone explain how i change this please. i have no virus's and i have run malwarebytes.

1) it does NOT appear as your using these in the RIGHT slots. NOTE your screenshots says SINGLE-CHANNEL. If you do NOT pair these together (slot 1 and 3 or slot 2 and 4, etc. depending on the Motherboard maker) they won't work in tandem.
2) Did you check your BIOS, and check you didn't have the second RAM turned off?
3) It appears the second one isn't working, did you try testing ONE RAM at a time, and make sure BIOS can see them individually, then in DUAL CHANNEL
4) make sure they are reseated correctly

does this look a bit healthier. i thought it was seated properly and i even checked it twice, but something must have been twisted or something.

The latest looks good, you prob have a fair amount of DRAM allocated to your 1GB GPU

Then please ensure you select the proper answer, but yes that is more accurate picture of proper hardware seating.
Still I would make sure (for optimal performance) to find the Motherboard model, look up the manual for it, check under RAM and see about how they should be in the slots (as I mentioned) to perform DUAL Channeling, just to make sure your getting what you paid for.

Yeah they are running dual now. thanks so much for the help.
