Notes:
1. 1Gb/2Gb/4Gb DRAMs are supported; however, only 2Gb and 4Gb DRAMs are validated.
2. Command Address Timing is 1N for 1DPC and 2N for 2DPC.
3. ES-4600 4S platforms do not support 3DPC UDIMMs.
4. Please refer to the ES-4600 Platform Design Guide for memory population rules.

Notes:
1. 1Gb/2Gb/4Gb DRAMs are supported; however, only 2Gb and 4Gb DRAMs are validated.
2. Command Address Timing is 1N.
3. Please refer to the ES-4600 Platform Design Guide for memory population rules.
4. QR RDIMMs are supported but not validated. Memory testing are limited to system level
testing. Signal integrity testing in interoperability testing are not performed. The passing QR
RDIMMs will be posted on the website.
