Because objective benchmarks are not available, the intent of this requirement is to define a memory size that represents the baseline of acceptable Windows performance.
The following summarizes the Windows Logo Program performance requirements.

Note 1: For systems with shared memory architecture and 128-MB system RAM, collectively, the drivers supporting integrated chipset functionality must not lock more than 32 MB. It is acceptable to use up to 8 MB from the 64-MB minimum in desktop and mobile PCs running Windows 98/Me or Windows 2000 Professional.
These maximum-page-locked-memory limits apply during all phases of system startup and normal operation. Page-locked graphics memory includes all frame buffers and buffers for hardware acceleration, texture and lighting, Z, and AGP. Page-locked audio memory includes all memory locked by the audio driver including all wave tables, and so on.
Dynamic memory allocation under the Windows environment is allowed, subject to the paged-locked memory limit. The driver cannot advertise or switch into a graphics mode that cannot be supported within the maximum locked memory limit.
Note 2: PC client systems must have at least the minimum system memory installed.
Note 3: Server system memory configurations specify the minimum allowed system memory to run the HCT. It is recognized that OEMs supply systems with specific feature requirements to corporations, which can include providing servers that do not include any preinstalled memory or that meet specific customer requirements for installed memory.
