Troubleshooting VMware Player : Configuring Memory Allocation

Configuring Memory Allocation
The Memory dialog box displays the amount of memory currently allocated to this virtual machine.
For ACEs, this menu item is available only if your system administrator has enabled it.
To change the amount of memory used by the virtual machine, use the slider under Memory for this virtual machine, or type in a value in megabytes (this value must be a multiple of 4).
The Memory dialog box provides the following information to help you choose an appropriate amount of memory for the virtual machine. A color-coded icon corresponds to each value. To use one of these amounts, line the slider up with the corresponding icon under Memory for this virtual machine.
Guest OS recommended minimum — The minimum that the operating system vendor recommends for the operating system to run.
Recommended memory — The minimum that VMware recommends for running this virtual machine. If you allocate more or less memory than is recommended, your virtual machine might perform poorly.
Maximum recommended memory — The maximum that VMware recommends for best performance. Allocating more memory to this virtual machine can have a negative impact on the host's performance, including the host's ability to run VMware Player properly.
