Unknown to me is whether the memory on the graphic card is irrelevant here in terms of memory usage of the card (I suspect it is relevant). The only thing I asssume, right now, about the memory on the card, which supports DX11 (wasted on me because I'm not a gamer, or 3d wonk), is that it is used by the GPU on the card to handle what is off-loaded to it for computation by specific apps.
Your GPU (and all your other devices) use memory mapped IO, which means that the 1GB of memory on your GPU is mapped to 1 GB of your CPUs address space. All other misc devices on your mobo do the same (but typically in much smaller chunks).

Thanks, Dan,
Illumination is always welcome here in the dark ...
A pretty obvious conclusion if I had really thought about it

Does he know that Visual Studio isn't "/LARGEADDRESSAWARE", and therefore doesn't use more than 2 Gigs? (Ok, that's not true, thats also editable)

The keyword here is "being used" as opposed to allocated. If you always have more physical memory than the green bar, then the amount of memory isn't a bottleneck.

Hi Jörgen,
Appreciate all your valuable comments very much !
My friend is using VS 2010 on Win Vista 64 with 8 gigs of memory, so he is probably not even thinking of "LargeAddressWare," but, given his knowledge of hardware and software, I bet he's aware of it.
His specific comment was that VS 2010 would "cache" more given 4 gigs on a 32 bit Win Vista system.
I will read up on "LargeAddressWare," thanks.
best, Bill

Keep in mind that just because the OS intalled supports a certain amount of RAM doesn't mean the BIOS of the motherboard can use it.
You would probably notice it a lot more with games. Things like loading textures into main memory from disk and then sending them to the graphic card can be helped tremendously by more RAM.

Hi T M Gray,
Thanks for your response !
The motherboard in question here is a P35 chipset, LGA775 socket, Gigabyte, about three years old, both motherboard and Award Bios, supporting up to 8 gigs in 4 simm slots with optional 800/1066/1333 FSB: in other words, compared to today's premium motherboards, an "antique"
However, you have given me an idea: I wonder if turning on the optional Vista "Aero" effects ... given the increase to 4 gigs of ram ... would now result in no difference in perceived speed of performance.
With only 2 gigs, and Aero glossy-glassy stuff turned on, there was a definite performance hit, which is why I have left them off.
As I said, I don't play any games on this machine other than C# in Visual Studio, so this may be irrelevant.
thanks, Bill

I am usually pretty good at fixing hardware issues, but this has me baffled...I have a dell 3100 workstation (about 4 years old) which refused to boot after a power outage...pressing the power button does absolutely nothing...no lights in front, no POST. Also, the fan did not spin up at all. Thinking it was probably the power supply, I swapped out the PSU with an older working PSU. The system powered up...problem solved right? I thought so too. A replacement PSU arrived within a week, which I hooked up, but no dice...same as the original PSU...nothing at all happens when the power button is pressed, and the fan (in the PSU) does not spin up with power applied. Weird huh? I tested the PSU with a voltmeter and it is good. The first thing I noticed was that the fan spun up when I shorted the green to black. So why not just keep the PSU that is working in it and forget about it?...because I can't put the case cover on with the working PSU, (the SATA power connector for the HD is not right-angle like the proprietary Dell PSU...also, the original PSU uses a 24 pin MB connector, and the working one uses a 20 pin. (actually, that I could live with) As I said, the PSU that works is a 20 pin MB connector and neither of the PSUs with 24 pins work at all, even though they test as good. Any ideas?

I don't have that type of computer, but I would check to see what is common between the 2 power supplies that don't work and different with the one that does. Is there a power cable different? Is there some sort of safety switch?
I'd venture a guess that there is a poor connection somewhere. A voltmeter can read fine, but once you draw some current, the voltage drops.
Good luck and let us know what you find out!

Thanks for the response! I have another box with a 24 pin MB connector that works. (although with the 20 pin MB connector attached) I think I'll take the time to try the PSU that I bought in that one. If it doesn't work, then I have to assume the PSU is bad, and will just get them to send me another. Will post back tonight with the results.

Yep, that would do it...now if I can just find these local, or spend $5 shipping for a $4 part! Thanks for the post!

I linked to amazon because it's eligible for free shipping if you tack it onto an existing order. IIRC Google turned up one for $6 or 7 shipped.

OK, this has me beat...
I have a 1GB CompactFlash card I want to use in my camera, and it shows up fine in Windows explorer with a single 61 MB partition and 923 MB of free unallocated space.
1) I right click on the allocated space and the option delete the volume is greyed out. I can format it, but I can't repartition the card at all.
2) All I can do on the unallocated space that shows up is a few options about adding spanned, stripped, and mirrored volumes.
3) The card itself has no switch on it to place it into 'read only mode' or 'protected mode' and I assumed that would have also blocked the formatting so...
I have formatted CF cards on my machine before without issues... but this Lexar card is kicking my butt for some reason. Keep in mind that it DID start out with this 61 MB partition as a bootable one (originally used as a HD for a small scale embedded VM system) and was running a a copy of ROM DOS.
Any one out there with any ideas?
Hate to just toss a 1 GB CF card in the trash if I can save it and use it with my camera.

Two ideas:
1.
Have you tried the Computer Management utility? It is part of Windows (since XP IIRC), and allows you to resize existing partitions and create new ones, at least on regular disks. I don't know what it will offer for CompactFlash though.
2.
Some USB sticks come with extra software that basically offers two partitions, a small unprotected one, and a second, encrypted one, that becomes visible and read/writable only once that software has been launched with the right password.

Yeah, that's where I do everything. Hmmm what I have NOT tried though is just plan old FDISK... might be worth it. Maybe something like Norton...
Luc Pattyn wrote: Some USB sticks come with extra software
Nah, not on these guys.. I know what's on them... I just have an odd feeling that windows is somehow freaking because the primary partition on this card WAS bootable, but looking it at shows no signs of any hidden files left, or anything odd like that. Might just end up digging around at the fdisk layer a bit...

More ideas:
3.
IIRC the bootability of a partition consists of a single bit; once cleared it should be gone.
4.
I regularly see messages telling Windows does not want to create/use more than one partition on some devices; can't remember any details though.
5.
if your CompactFlash also fits in another device (say a camera, a media player), maybe you can have it formatted there.

Hi , have a good
Is there is some kind of wireless router or wireless device "CAN SEND" long range wireless signal ,
P.S :
long range : 1 KM - 5 KM ,
Thank you !
I know nothing , I know nothing ...

Your device needs to have an external antenna connection. Then make a search for "Directional Antenna".
But remember that the radiofrequency of unlicensed wireless routers (b,g,n) is the same as for a microwave oven (2450 GHz), which means that all humidity absorbs your radio output.
And on top of that, the maximum power (unlicensed) is 50 mw.
So, if you don't live in a desert, the actual range might be quite random.

I use long range wireless radios for electrical substation monitoring and control, and regularly manage 10 - 15 mile links with off the shelf equipment. It isn't cheap, but it's a lot cheaper than all the alternatives. GE, Motorola, Proxim, Ubiquiti are a few manufacturers that provide the equipment, with Motorola being the most expensive, and Ubiquiti the cheapest. Ideally, I'd use fiber, or even DSL, but fiber is too pricey, and DSL isn't an option; phone companies don't like bringing their copper lines into an electrical substation. It seems their switches have alergies to 25kV+ signals.

If going into the zap room was the only concern, DSL terminating at am 802.11 box a safe distance outside the substation would protect their magic smoke.

I know; for that matter, it wouldn't be too hard (or costly) to build an optoisolator and install it in the line just outside the fence. Heck, it's very likely an off the shelf item I can pick up from a catalog by now. I think they're just jealous that we can make much bigger smoke signals than they can.

I limited my suggestions to wifi because that wouldn't require them to trust you to know what you were doing. IF they did that in the 1st place the whole issue would be moot, and they'd trust you to do this without being prodded.
