Should I buy more RAM..?

65 bucks...2Gb DDR2..

I could go from 1.5Gb to 3Gb, and be able to transplant this into a newer system later on. Hmm. Then again, perhaps prices will continue to drop? I dunno...what do you think?
woot!

Hard to believe I could run 4Gb for under 150 bucks...but doesn't 32bit Windows crap out at 3.5Gb? :P
woot!

I was under the impression that XP's RAM limit was not under 4 GB.

Yeah, I think you're right; 4Gb it is. I doubt I'd see much difference, though..but it's awfully tempting..just because I can..lol
woot!

If you use XP, I'm pretty sure it doesn't use anything over.

Holy **** thats 667.

DO IT ANYWAYS.

Frys is awesome.

I love how where everywhere else fails, Frys is always there and usually has the product I'm looking for.

XP can only allocate 3GB, and that's only with a special boot option.

I thought they fixed that in SP2 Cool Matty? Or was that the HDD size thing?
VTEC just kicked in, yo!

I could be wrong, I just remember reading that on SomethingAwful.

It was the HDD thing. There's no way to fix a 4 GB limit with a 32 bit OS.

Is 5 an average CAS latency for DDR2? ****ing christ...

XP can allow 4gb with a special boot option, but anything over 3gb is wasted because it doesn't actually use that last 1gb of RAM.

PS, prices won't continue to drop I can almost guarantee. RAM seems to level out at about 50-70 bucks/gig with every new iteration.

That's for user processes, and per process. Default is 2gb for the user process and 2gb for the kernel, which can be changed to 3 and 1 with a boot switch. Actual limit is probably 4gb for 32-bit OS? It's 128gb for 64-bit ATM, although it's an easily expanded limit (128gb was an arbitrary limit, the real 64-bit barrier is much much higher).

wow, awesome deal. bought it just now.

Doesn't XP support PAE, which provides four more address lines for accessing memory, bringing the maximum amount of RAM up to 64 Gb? Even though a single process cannot address more than 4 Gb at once, the system can manage the extra memory and trick the processes into using the extra memory. I know FreeBSD and Linux support this and I'm pretty sure that Windows does too.

I thought one of the advantages of Linux was that Windows didn't support that.

(And I was apparently wrong)

Yes.


As previously mentioned, as well, processes are allocated 4 GB pages, with the high 2 GB reserved for kernel use. Visual C++ supports an additional compile flag to allow 3 GB/1 GB split, and there's the boot option mzzt mentioned before.

That sucks - they said my CC's address match failed, so my order didn't go through...bah.

Edit: Fixed the issue with the CC company...called customer service and had my order put through again! w00t. :)
woot!

I think it's something like 128 PB. I don't think that that'll be much of a problem this side of 2050.


Honestly, I don't think I've ever heard of anyone with 32bit XP seeing the full 4 GB of memory.
