Title: PC Specifications for SDR-1000
Tim
Ill take a stab here. However, you
realize that this is also somewhat of a political question and there are MANY
motherboards out there. I have an ASUS micro ATX MB with
a 3.6 mb Pentium 512 of ram with the (not exactly sure what it is called) but
bank selected dual access to the ram. You dont say if you
are going to build or buy a system the choice is VERY important! A package
system from Walmart, is a lot different from the myriad of put it
together yourself Modding systems!. My system above works fine with the
SDR and I can get you the specs if you want. It was about 610 with the MB and
512 mb. With 2 mb cache. I run a max of 20% CPU load with SDR running and this
will improve as they go to direct-x and make the code more efficient. The SDR
runs fine on the hardware, and the only limitations are really in the code
produced to date.
I really dont think that with XP
you have control over some of the parameters you have listed.
I also dont know whether dual cores
are available yet (I go through about a 3 year cycle now before I start
comparing MBs and they come out daily and I am only at about 1.5 years
now). Obviously a dual core system it pretty slick rather than 2 processors on
board. Much more efficient on the die.
My priorities on your list are:
Cache as much as you can afford and is
offered. Although quite frankly I have never checked how much of that ultra
speed scratch is in use at any time!
Memory? Sure go for it Dual Access.
Dont wait to order the SDR. Your
questions sort of indicate you are a modder and probably have more than enough
to run the SDR. My MB is most certainly 1.5 years old and there are better out
there now. It loafs even with NAV and many other co-processes running at the
same time.
You can always up the priority of
Powersdr.exe.

Recommendations for SDR-1000
Hi all,
I think my inquiry may have been lost in
the noise and fury of the e-mail barrage of the past two days, so I am
re-posting my request in the hopes that I can get some additional feedback on
my questions other than use LINUX. At this time LINUX isnt an
option. Maybe it will be in the future.
I really want to get my PC taken care of
so I can order my SDR1K and really join the fun!

Specifications for SDR-1000
To all,
I am starting to put together a PC system for use
with a SDR-1000 and PowerSDR I am planning to get in the near
future and had a couple of questions.
What performance metric is most desirable in a CPU /
motherboard combination? I want to make sure I get a system
that will meet current and future performance needs. I have not done a
lot of research on the DLLs or libraries used, so I was hoping to get some
insight from those that know a lot more about the internal operation of
PowerSDR than I.
Specifically, what is most to least important of the
following items (a ranking of sort):
Floating point performance
Integer operation
Memory performance
Multi-tasking performance
CPU cache
Graphics performance
In addition to processor / motherboard metrics,
has
anyone used Windows XP Professional x64 with
PowerSDR? If so how did the WOW64
emulation handle PowerSDR and is there any advantage to using a
64-bit OS.
Will PowerSDR be compiled to be a 64-bit app in the
future?
Also, are there any known
compatibility issues with AMD processors?
In advance, thanks for the information.
