1、Buffer和Unbuffer
Buffer即缓存器，也可理解成高速缓存，在服务器及图形工作站内存有较多应用，容量多为64K，但随着内存容量的不断增大，其容量也不断增加，具有Buffer的内存将对内存的读写速度有较大提高，象早期168芯EDO ECC服务器内存大多都带Buffer，Unbuffer表示不具有高速缓存。有Buffer的内存几乎都带ECC功能，Unbuffer内存只有少数带ECC功能。其在内存编号上也有较明显特征，以维京内存PC133 128M为例，其编号为ME16641U4SS3-CL3，其中的字母U就代表Unbuffer。
2、Register
Register即寄存器或目录寄存器，在内存上的作用我们可以把它理解成书的目录，有了它，当内存接到读写指令时，会先检索此目录，然后再进行读写操作，这将大大提高服务器内存工作效率。带有Register的内存一定带Buffer，并且目前能见到的Register内存也都具有ECC功能，其主要应用在中高端服务器及图形工作站上，如IBM Netfinity 5000。
3、SDRAM
即同步动态随机存储器(Synchronous Dynamic RAM)内存。该内存历史较长，它的特点是让所有的输入输出信号保持与系统时钟同步，内存就是工作在系统的外部频率下。工作电压3.3V。
4、DDR SDRAM
双倍数据速率(Double Data Rate，DDR)SDRAM是一种以SDRAM为基础发展而来的内存技术。因此，DDR内存加倍了内存的频宽，提高了数据的传输量。DDR内存工作电压为2.5V。 由于DDR内存比SDRAM能增加更多的效能，并且能降低成本，而且DDR内存晶片能用现有的SDRAM设备制造及测试，不必再投资大量资金用于设备及生产上。此外DDR内存增加了内存频宽及效率，因此广泛使用在许多商业、多媒体及娱乐相关产品上，将逐渐取代SDRAM。
5、DIMM(Dual-In line Memory Module)-双边接触内存模组
形象的说:内存条正反两面金手指是不导通的，如常见的有100线、168线、200线内存(long Dimm)和72线、144线(SO-Dimm)。DIMM一般有64位带宽，并且正反面相同位置的引脚不同;而SIMM一般只有32位带宽，需要两条两条同时使用，一般通过72线金手指与主板相连。
编号有P、R和F三种，分别表示带校验的registered内存、普通服务器用registered内存以及前两年特别火的FB-DIMM
| Unbuffered Ecc DIMM | 低端服务器工作站内存 |
| Registered DIMM | 高端服务器工作站内存 |
| Fully Buffered DIMM | 全缓冲服务器内存 |
在产品报价上看到产品名称带FB的，一般都为全缓冲服务器内存，暂不需要考虑此类产品
要带ECC纠错技术，通过IC颗粒的分布可以看出是否带有ECC功能，ECC比普通NO ECC内存多1颗IC芯片

Xeon (DP) & Xeon MP (64-bit)
[edit]Nocona and Irwindale
Due to a lack of success with Intel's Itanium and Itanium 2 processors, AMD was able to introduce x86-64, a 64-bit extension to the x86 architecture. Intel followed suit by including Intel 64 (formerly EM64T; it is almost identical to AMD64) in the 90 nm version of the Pentium 4 ("Prescott"), and a Xeon version codenamed "Nocona" with 1 MB L2 cache was released in 2004. Released with it were the E7525 (workstation), E7520 and E7320 (both server) chipsets, which added support for PCI Express, DDR-II and Serial ATA. The Xeon was noticeably slower than AMD's Opteron, although it could be faster in situations where Hyper-Threading came into play.
A slightly updated core called "Irwindale" was released in early 2005, with 2 MB L2 cache and the ability to have its clock speed reduced during low processor demand. Although it was a bit more competitive than the Nocona had been, independent tests showed that AMD's Opteron still outperformed Irwindale. Both of these Prescott-derived Xeons have the product code 80546.
