Server Ram, Anyone if PC2-5300p is backward compatible with PC2-3200R Tags: RAM Compatibility Servers Networking Last response: October 23, 2011 2:24 AM in Networking Share scampy_008 October 23, 2011 12:04:14 AM Hi All, Both PC2-3200R (400Mhz) and PC2-5300P (667Mhz) are ECC Registered types of RAM, mainly used in Servers. Please dont tell me they are different types of memory because they are same. What I would like to know is if PC2-5300P is backward compatible on a server that uses PC2-3200R. Example HP Proliant DL145 G2 Crucial seems to think so as they advertise PC2-5300 ram as suitable for the machine in question, heres the link http://www.crucial.com/store/listparts.aspx?model=ProLi... Have Crucial got it wrong or are HP afraid to tell to customers to use faster backward compatible memory? Replies needed ASAP, Thanks PS Also anyone know they changed from the "R" to the "P", as with DDR3 they are know back to "R" More about : server ram pc2 5300p backward compatible pc2 3200r arael October 23, 2011 2:24:37 AM Should work perfectly fine. Though the speed will be limited to whatever the motherboard can support. Can't find your answer ? Ask ! Publish Related resources: ForumHow important is backward -compatibility to you?...
