DC7600 sff desktop memory Upgrades

[rocshoc]

As a teacher running a TV studio in a public school, tight budgets force me to take what I can get to run the studio. A parent donated an older DC7600 SFF with win 7 64 bit OS. It has 4 1gig pc4200 Ram sticks, the max under Win XP 32bit which put in after finding some random sticks including a 6400.  I have an intereste in using 5300 4x4gb ticks but have to buy them as HP site says I gould due to Win7 64.  Will the DC7600 run pc6400 Ram sticks (240 pin style) for I have 4x 2gb sticks of that They are probably CLA 6 as opposed to the older RAM with a CLA 4. 

Owners Manual says:

For proper system operation, the DDR2-SDRAM DIMMs must be:
■ industry-standard 240-pin
■ unbuffered PC2-4200 533 MHz
■ 1.8 volt DDR2-SDRAM DIMMs
The DDR2-SDRAM DIMMs must also:
■ support CAS latency 4 (CL = 4) for DDR2/533 MHz
■ contain the mandatory JEDEC SPD information
In addition, the computer supports:
■ 256Mbit, 512Mbit, and 1Gbit non-ECC memory technologies
■ single-sided and double-sided DIMMS
■ DIMMs constructed with x8 and x16 DDR devices; DIMMs
constructed with x4 SDRAM are not supported

However, I did find this for ANY and ALL future concerns for people like me that still find memort a bit of a quandry sometimes - THANKs HP for referring me to the CRUCIAL.com werbsite:       

DDR2 PC2-4200 (commonly referred to as DDR2-533) memory is DDR2 designed for use in systems with a 266MHz front-side bus (providing a 533MT/s data transfer rate). The "4200" refers to the module's bandwidth (the maximum amount of data it can transfer each second), which is 4200MB/s, or 4.2GB/s.

DDR2 PC2-5300 (commonly referred to as DDR2-667) memory is DDR2 designed for use in systems with a 333MHz front-side bus (providing a 667MT/s data transfer rate). The "5300" refers to the module's bandwidth (the maximum amount of data it can transfer each second), which is 5300MB/s, or 5.3GB/s. PC2-5300 is backward-compatible for PC2-4200.

DDR2 PC2-6400 (commonly referred to as DDR2-800) memory is DDR2 designed for use in systems with a 400MHz front-side bus (providing an 800MT/s data transfer rate). The "6400" refers to the module's bandwidth (the maximum amount of data it can transfer each second), which is 6400MB/s, or 6.4GB/s. PC2-6400 is backward-compatible for PC2-4200 and PC2-5300.

DDR2 PC2-8000 (commonly referred to as DDR2-1000) memory is DDR2 providing a 1,000MT/s data transfer rate). The "8000" refers to the module's bandwidth (the maximum amount of data it can transfer each second), which is 8000MB/s, or 8GB/s. PC2-8000 is backward-compatible for PC2-4200, PC2-5300, and PC2-6400.%MCEPASTEBIN%
