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.

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.

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

Your reply is logical and I guess I was lured into 1:1 by Giga-Byte's recent
1333 bios release statement.

Having used computers and programming before the "personal computer" and
passing college courses including "solid-state electronic techniques" I do
wonder whether I should try to keep up with you younger folks!

thanks,

Yes I think the bubble memory was made by Plessey in the UK. I also
worked with it in the (US) General Electric Mark Century CNC

I think you will find that there are a bunch of "old timers" that frequent
this forum........:-)

WOW!!..........you are really old Phil........:-) The first core memory
boards I worked with were on those Avis car rental "Wizard" terminals in the
early-mid 70s (Some independent Avis dealers used them until the early
80s).......Think they were about 100-128k, about 2'x2' in size and probably
cost in the area of $20,000-25,000 IIRC. They worked with old IBM Selectric
I/O terminals on a nationwide polling network.
