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

Is this (DDR2) PC10664?

I cannot find this although the Giga-Byte GA P45-DS3R now supports it.

1333 X 8 = 10664, so yes, DDR2-1333 is PC10664.

You can find DDR2-1333 memory the same way anyone else can find it. Use
Google.

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.

Pretty impressive result. Close to DDR2-1400, at CAS5.

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.

Phil,

Sorry about the self post and format.


I had already Googled for DDR2 1333 and anything that came up just
speculative statements made a couple of years ago but nothing from vendors
offering current product.

Tried your link but got www.eataonline.com could not be found. Please check
the name and try again.

Phil,

I had already checked out the Giga-Byte sites but was looking at the wrong
memory tables. From your Team link I now realise that this PC10400 is way
beyond my requirement (and ability). I will lower my sights and lurk a
little on the team forum.

thanks,

Beemer

Why do you want 1333MHz memory? 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.

OK, the correct URL for eataonline is http://www.eataonline.co.uk .
Each of the memory module manufacturers DO in fact at this time supply
PC10664 DDR2 memory.
Using the search string I posted, "DDR2 1333" site:uk DOES return the
correct URL for eataonline.

If a posted URL does not work, consider that there may be a typo, and that
additional clues in the post may point at the correct URL. As it did in
this case.

Strictly speaking, you CAN overclock the FSB AND set the memory clock to the
DDR2-1333 rated speed, depending on the motherboard. 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.

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.
