Windows 7 64bit RAM problem Tags: RAM Windows 7 Memory Last response: February 18, 2014 11:44 AM in Memory Share Radu Bortan February 18, 2014 9:25:02 AM Hi. I have a PC running Windows 7 Home Premium with 6GB of DDR3 RAM. Sometimes my PC gets really slow. When i open the Task Manager in the Performance menu it shows this : Why only 4115MB of 6111MB are available? Sometimes it gives me this : Why only 1123MB are available? And how can the quantity of used cached RAM be bigger than the available quantity? Why it doesn't use all my memory? It never uses more than 5000MB.

Available=total-used Free=total-cache-used If you have 6gb total and 4gb is available, it means you have 2 gb used. When you have near 1 gb left, windows will start paging more aggressively. m 0 l Can't find your answer ? Ask !
