2*ddr2 800 2G memory + sempron3000+ can't start up

but 1 ddr2 800 2G memory + sempron3000+ can start up


the motherboard manufacturer think it is the problem of cpu,


is it ture?


thanks a lot



hope god can understand my poor english~

this is what i found.



AMD Semprontm Memory Guidelines

In our ongoing efforts to support industry standards, AMD Semprontm processor-based platforms may be designed to leverage industry standard DDR registered DIMMs. An independent testing company, Computer Memory Test Labs (CMTL), has conducted memory compatibility testing. CMTL is an independent test facility and is able to test RAM modules from different module suppliers. System builders should access the CMTL web site a www.cmtlabs.com and view the recommended memory module list for the specific motherboard manufacturer and motherboard model.

Note: The CMTL website is provided for informational purposes only, and AMD recommends that a system builder conduct its own testing and validation to confirm that the memory modules are suitable for its systems.

Memory Supported

Several AMD Semprontm processor-based motherboards currently support some of the following memory features:

PC1600, PC2100, PC2700 & PC3200 unbuffered memory modules.
184-pin 2.5-Volt DDR DIMMs.
64-bit DDR memory bus.
Supports 64-Mbyte, 128-Mbyte, 256-Mbyte, 512-Mbyte, 1-Gbyte, 2-Gbyte and 4-Gbyte memory technology.
Supports production DIMMs from industry standard DRAM memory manufacturers.

thanks

afaik an AM2 Sempron should support standard DDR2 RAM just the same way as any
other desktop AM2 CPU, except some RAM frequency settings may not be available or incompatible.
You might want to study that in order to get both sticks running.
In BIOS Try to set the ram running @ DDR 667 or close to it, to start with.

DDR800 = PC2-6400
DDR667 = PC2-5400
