Lauren I think that you need win64 and at least 4gb of memory.

Lauren I think that you need win64 and at least 4gb of memory.

Well I guess that leaves me out in the rian

[Chuck]

To all.... especially anyone who thinks I don't know about windows.......

gets on stepladder <coughs> and offers an oratory to laugh at like the Barker who's actually one of the Clowns at the Circus.... I just ask you to laugh!!!!

To all.... I"ve been using DOS since the 640K of memory days when we had to put extra data into EMS memory..... Can you keep up with me there???? I've also used Regular Windows 3.1, written code in it and a whole bunch of other things you don't want to know. Heck, my ASR-33 with punch still works at a whopping 110 baud of 60 ma current loop. I built my own computers when 2k or 4k made you BMOC and BOTH my 4k and 256 BYTE computers still work!!!!!!

As for 64 bit Windows??????? I'm writing you now from a DUAL-BOOT AND Virtual Machine'd Vista-64 home premuim machine (a VAIO VGN-AW230J) ...... My OTHER laptop is a HP DV7-4170-EN/US with Win-7 Professional with the same capabilities... Yes I take advantage of my Microsoft Virtual PC license and use it!! I do the reverse too!!!.........I boot Linux in VPC when I need it!

I'll be the first to admit!!! Each OS has it's audience and therefore a need, otherwise they wouldn't be here....


It sounds like you're politely saying I need to get 'l**d'..... PERHAPS!!! I've been divorced since 2001 and my girlfriend isn't ready to get married.... not to say.. .um never mind... mixed company here!... She says I need to learn better Swedish, Portuguese, and proper Spanish from Spain. Add to that we already have 3 other languages we mess with people. FYI, she's a year older than me and just as quick tongued and frisky (P.c. words for mixed company) and just as quick to hop a plane somewhere for the weekend or rent one and fly ourselves for a quick get away! She's a nuclear physicist if you must know AND dual Brazilian / Swedish heritage. My own son & daughter-in-law (age 28) say they can't keep up!!! (she's Italian / Corsican).


There's only one place we cry.... when someone get's out of school, after having worked their buns off, with or without family help, and STILL can't look inside a PC and find the North Bridge, South Bridge, handle all the motherboard jumper settings, or know what "ELI the ICE man" means and how to use it or write code in anything other than Java or Python!!! Oh, you don't have a digital meter you say? Will this old analog one work or how about this O-scope to figure out what's wrong with the circuit? What? You need a logic analyser? Why? your scope not enough to trigger on and display the signal traces? You don't know assembly language and can't write some quick code to exercise the problem with precise signals stimulated?

As per the Barker..... "Come one, Come all, Sit down and have a laugh and may we 'Let the show begin!!!'"


<quietly and humbly stepping down>....

Find a coin with head faced up and all the day you'll have good luck!!!

Have a great day everyone,
Cheers,
C.


PS: So what's that reference to win64 and 4 GB supposed to mean anyway? Variety is the spice of life, true?

[AMDave]

a 32-bit OS cannot normally address more than 3-ish GB RAM because it runs out of memory rigisters (read that as - 32 bit limited)
that said there are some work-around updates and patches out there that can 'fold' RAM for some software to access RAM above that limit.
because 64-bit OSs have longer registers they can can access greater amounts of RAM, by design

that is one aspect.

the other aspect is that some DC projects lend themselves well to better use of larger registers (not just greater amounts of RAM)
it is evident in some cases that a 64-bit version of a program is 'faster' than the 32-bit version.
However this depends upon the type of problem and the type of algorithm that is best suited to solving it.
There are still plenty of projects where a 64-bit version of the client will not perform faster, and sometimes perform slower.

This performance gap becomes even more evident when looking at 128-bit architecture.
The performance gain is much less for the majority of solution deigns because we either don't know how to think that big yet, or the problems we try to solve just plain don't need it.
That said there are High Performance Computing bottlenecks begging for 128-bit solutions, but mostly in data transfer and networking.
We just don't have that much RAM on a chip yet to make it a necessity,

HTH

AMDave,
Is it not true that in 32-bit Windows the user-space is pretty much exhausted (program & heap) after about 2.5G of the permissible 4GiB address space
and with respect to 64-bit math... it's simply a case of efficiency where a 32 bit program might require 3 instructions for a multiply, a 64 bit version of the same could do it in 1 or 2 instructions and the slowdown we see is a by-product of cache faults and other memory bus traffic collisions ?

I reference the well known 'Montgomery Math' which may require 3 or more instructions to do what 64 bit math could do in 1 thanks to the register width increase?

Does this not infer why we are so partial to the SSE and SSE2 instruction set extensions where we do math in 128 bits as well as execute a single instruction over a large block of data (hence the name
SIMD) ?


Cheers,
C

[AMDave]

Yes.
But your "PS" question got me going
My life is spiced like 64-bit, so I get l**d a lot.
128-bit makes me sweat just at the thought!
At my age I might not be able to handle it

Then you don't want a user account on the 128-bit machine???? It's not that hard to use, heck I do. It's just a 'Double' is 256 bits... THAT messes with the brain a bit... and we won't talk of a 'Double Double' ... Kinda like a 'Double Bok'. VERY Intoxicating .... err.... Satisfying!!!!!!

Oh, FYI... don't tell anyone (SHHHHHH).... L2 cache is 1024 bits wide for a VERY obvious reason.... soon to be 2048 bits wide...... with 4096 on the bench......... Just don't tell anyone.

(be wery quiet, I'm hunting wabbits)
