can i buy ddr2 1333MHz?
I want to buy 2 x 2GB of DDR2 (not DDR3) 1333Mhz memory. Who makes this
and can I buy it in the UK? regards, Beemer |
can i buy ddr2 1333MHz? Is this DDR2 PC10664?
Is this (DDR2) PC10664?
I cannot find this although the Giga-Byte GA P45-DS3R now supports it. regards, Beemer "Beemer" wrote in message ... I want to buy 2 x 2GB of DDR2 (not DDR3) 1333Mhz memory. Who makes this and can I buy it in the UK? regards, Beemer |

Who makes this and can I buy it in the UK? regards, Beemer You can start with the memory list on the motherboard web site. http://www.gigabyte.com.tw/FileList/...-ep45-ds3r.pdf They tested 2x1GB of Team TXDD1024M1300HC6, a memory rated at DDR2-1300 and overclocked by them to DDR2-1333. The results say only one DIMM per channel at that speed. Whether such a module is practical, would depend on what voltage is needed to get the module to run that high. One product I was looking at, had a 2.3-2.35V spec for Vdimm, to make over DDR2-1200. How long will the RAM last with that kind of voltage ? That is the question I'd want an answer to. Some people also place fans above the memory area, to help with the heat. That might make a difference to the stability, especially when running something like Prime95. On another site, someone was using the Team product, and lists this as the specs. The voltage spec is pretty high. (High enough, you'd want to check the Vdimm range on your motherboard.) 2X1GB kit of Team Group DDRII 1300 CL:6-6-6-18 (2.35-2.45) memory kit. TXDD1024M1300HC6 The modules are at the top of this photo, and are hidden underneath two fans. That is how "hard core" you have to be, to use memory like that. http://www.cyberimpressions.net/out....8_SUNP0040.JPG Pretty impressive result. Close to DDR2-1400, at CAS5. http://valid.x86-secret.com/show_oc.php?id=386664 Team Group don't seem to make any 2GB DDR2 modules. There are differences between the chips used to make 1GB and 2GB modules, and apparently (something I read on Anandtech), there is a bit of BIOS tuning to do for each. And tweaking 2GB modules might not be as mature as 1GB modules. http://www.teamgroup.com.tw/teamgrou...s.php?pl1_id=1 Paul |

The bottleneck in a Core2 system is the FSB not the RAM. The FSB is only 64 bits wide which means that the fastest RAM the bus can handle is the FSB speed/2 (because each DIMM in the pair is also 64 bits wide). The fastest FSB speed available is 1600 which translates into DDR2 800. DDR2 1200 is widely available. 1200 is a 50% overclock of the FSB which is more than enough. BTW most motherboards have a maximum FSB of 1333 not 1600. |

With nVidia chipsets for Intel Core 2, for example. Though I don't use DDR2-1333 memory, I do use DDR2-1066 @1200 MHz with an EVGA 680i nVidia chipset motherboard and an E4300 with a 1200 MHz FSB for a 1:1 CPU clock : Memory clock ratio. The performance gain, is, however, only a few percent over a 2:1 ratio with the memory clock at 600 MHz. Memory is so cheap at the moment that it isn't unreasonable to buy the fastest DDR2 available as long as you are aware that the $15 US or so per GByte premium for DDR2-1333 over DDR2-800 brings only single digit performance percentage increases.

BTW most motherboards have a maximum FSB of 1333 not 1600. More memory is much more important than faster memory. The caches on the Core2 are huge so it's not that sensitive to memory bandwidth as you pointed out. Buy slightly faster memory then the speed that you are running at does make sense from a reliability standpoint because it gives you more timing margin. So if you plan to run at 800 then buying 1066 and underclocking it to 800 would give you a more reliable system then using DDR2-800. |
