I have some RAM that is (apparently) bad. However, it passes a memory test just fine. Why?

Why might a process not use all available physical memory under Windows Server 2008 r2 standard? I have 32Gb of RAM acknowledged by Resource Monitor, of which 19.4 are allocated to a process (the IBM solver CPLEX running in command line form from Power Shell) that has just thrown a controlled OOM error despite there being another 12 Gb marked as available.
I'm going to assume (to start with) that the program itself isn't the culprit, but is there a per-user limit switch, a per-process limit switch or something similar in 2008 r2? Any other ideas?

A few weeks ago, I put into my new Macbook Pro (2.3 i5) 8GB 1333Mhz DDR3 RAM in it from Crucial. The result was Kernel Panics and unstable applications. I reinstalled the (4GB) Apple RAM, and the problem went away. Crucial sent me replacement memory, I installed it, and guess what?

I recently bought a new Macbook Pro (2.3 i5) and almost immediately put 8GB 1333Mhz DDR3 RAM in it. Almost immediately, I got a kernel panic, and then Chrome would crash every once in a while. I have also had occasional crashes of Pages, MailPlane, and BusyCal, but no more panics. It has been about a week or so since I installed the RAM. Do you think I have a bad memory stick, or is this occasional crashiness related to something else?

I currently have an Asus eeepc 1005P. I want to add an extra 1gb of memory to it, but I'm unsure of what kind of RAM I should be buying/looking at. I've looked at a few other forums and such but they seem to be a little vague as to what exactly I should be looking for. Help would be much appreciated

I have a HP Pavilion dv6700 (dv6780se) laptop which i recently upgraded to Windows 7 pro via a free copy from the msdn alliance. I am currently running 3 gigs of physical RAM in 2 slots. I recently read an article suggesting a change to the virtual memory paging file size. From what i gathered you should or can increase the size by multiplying the current amount times 1.5.
This would change my total virtual memory to 4605, is this wise?
Should i leave it on the save hard drive has my OS or move it to a partition or separate external hard drive?
I've also read that readyboost can increase performance... is this still quite debatable for Windows 7 and am I already pushing the limits of my RAM and virtual memory?

Apple support told my mom 3GB of memory in a
Late 2006 MacBook (1.83GHz C2D, Snow Leopard) could overload the processor. What could they have meant by that?

My computer will tell me it's using so and so much RAM. When I add up the RAM usage in process manager, there's no way it's that much. Where is my RAM going?

I inherited a barely-used 2004 Dell laptop, Pentium M 1600 MHz, 30 GB hard drive, Windows XP, Mobility Radeon 9000, 512 MB RAM.
Is it worth reformatting and upgrading the RAM to its 2 GB max (at $100), for a few more years of basic internet and Open Office, or as a whole will it forever lag in current-and-near-future contexts?
It could be a decent tool for my commuter days as an undergrad, though it is currently far too slow going to be productive or entertaining.
Thanks for ideas!

I'm ready to buy a new desktop PC with Windows 7, and I can't decide whether to spend more money on a faster CPU or more memory, if either. Which would be better in the long run: i7-860 (or even i7-920) with 6 GB RAM, or i5 with 8 GB of RAM? Considering the CPU alone, is an i7 instead of an i5 worth the extra money?

I'm a hard core Mac nerd who's a total Windows novice. Can you explain the weird RAM and graphics memory totals I'm seeing in Windows XP (SP3) on my MacBook Pro, and give me some idea of what I can actually expect when it comes to performance in games?

How is memory typically mapped to the different chips on a DIMM, and what are the typical timing characteristics, broadly speaking? For example, are bytes/words whose address is i mod 8 typically on chip i? In the case of reads, are results returned first from chip 0 (after the RAS and CAS latencies), then promptly on subsequent cycles from each of the next 7 (or 15) chips? How about from other DIMMs on the same motherboard?
