PC150 SDRAM Roundup

OCZ Enhanced SDRAM



The Overclockerz Store was started up as a online hardware store that sells PC equipment such as memory, CPU, hard disks and video cards but more importantly they sell CPU, RAM and video cards that are pre-tested to do a certain (overclocked) speed. We were fortunate enough to receive a 128MB PC133 SDRAM stick from OCZ that was pre tested and rated to operate at 150MHz. According to Ryan from OCZ, they "hand pick" Micron memory for their chips and only the best of the best chips are used. The OCZ Enhanced, uses different chips than the green memory chips used on Micron's own brand and this is single sided 6 layer PCB for extra stability at high speeds.


In OCZ inhouse testing Ryan from OCZ told me they were able to archive higher operating frequencies then we were able to in our testing, we are not sure why this is the case though. It may have been that OCZ tested on a different chipset and resulted in better results. For example, testing was done on a VIA KT133A chipset based board and that this RAM was given to us before KT133A was even created, so this may have something to do with it... Remember, if you buy OCZ memory you very well MAY be able to get higher operating frequencies then we were able to, but this should really be considered the case for all of the memory in this roundup.


OCZ Memory Features


PC133-222 Specification:


Maximum Rated Operating Frequency = 133MHz


CAS Latency = 2


RAS to CAS Delay = 2


Precharge Delay = 2


Device Cycle Time = 6.6ns


On-Board Serial Presence Detect (SPD)


JEDEC PC-133 SDRAM DIMM Compatible


While the DIMM only has an official rated speed of 133Mhz don't let this fool you, this RAM is easily capable of 150Mhz and higher.
