Diminishing returns on mobile devices?

With the news of the iPad Air and it's wonder 64-bit A7 processor, my curiosity is up again. Will mobile devices, phones or tablets, hit a point of diminishing returns in regards to processing power and/or RAM?

Is more memory the answer to my problems?

I've got a four-year old PC running vista. It's got 4gb Ram and a 1tb storage. It's never been a high performer, but lately its been running really slow, especially on start up and getting really clunky when I have, say, four of five applications running. I've been considering buying more RAM to speed things up a little. Is more memory the answer to my problems?

Powerful & Fast Computer for around a grand

I need a new Desktop PC and I want it to run well. First, what are good combinations of processor and memory? Intel's Ivy Bridge I7 processors look the best, and I'm guessing 10 gb of ram would suffice, or would it? I'm not buying an Apple, but HP? Compaq? Dell? What combination of processor/ram/brand would you recommend for a desktop somewhere around a thousand dollars? Thanks! [more inside]

Which should I get: a faster CPU, or more memory?

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? [more inside]

How do the chips on a memory module interrelate?

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?

How much memory can my computer hold?

How much memory can my computer hold? My computer specs: Dell XPS 600 OS: WinXP Professional 5.1 SP2 (Build #2600) CPU: Intel Pentium D , 2.99 GHz, 1024KB Video: NVIDIA GeForce 7800 GTX (1920x1200x32bpp 60Hz) I went on crucial.com and their scanner said my computer can have up to 8 gigs of memory but a friend of mine told me that XP can actually only hold 3 gigs of ram. How true is this? I currently have 2 gigs of ram and I was looking to go as high as 5 mainly because I work with After Effects a lot and rendering is a pain in the ass. Thanks in advance everyone.

Missing MegaByte

I'm trying to work my way through the activation process for my new RoadRunner service. The flash wizard that analyzes my computer tells me that I have only 127 MB of RAM, 1 short of the necessary 128 to continue setup. My computer disagrees with the wizard. Is it even possible that this is the case? If so, how do I get back my essential 1 MB?

Should I RAM one slot, or two? Huh huh.

I'm thinking about buying a new iMac G5, and I'd like to bump the RAM up to 1GB from the standard 512MB. The Apple customization menu gives you the option of getting 1GB in two DIMMs or one; the latter is $50 more expensive. Is there any performance benefit in having all the RAM in one place, or is it just a question of keeping a slot open?

Old Mac Memory

Having recently splashed out on a nice black PowerMac 5500/275, I want to upgrade the RAM. I'm aware that it takes 168pin, 5v EDO DRAM (up to two 64mb DIMMS), but finding these in the UK is tough. I won two 64mb chips on eBay at 1p, but they're the wrong voltage. Anyone know a (cheap) supplier of the stuff here in England?

Apple Memory Upgrades

A long-time PC user, I am planning to switch to Apple, replacing my centrino laptop by a 12" ibook G4 (I want a small computer).

Most of the standard Apple configurations come with 256MB of RAM: is this because OSX needs less memory than XP (since most laptop configs today come with 512MB), or do I need to go for 512 (768?) megs?

I mainly use my computer to browse the web, send & receive e-mails, do some word processing, and manage my MP3, which I only store on my iPod.

Other question:
If I buy the computer at the local Apple Store (I'm in NYC), I'll only be able to get a memory upgrade, and not a hard disk upgrade. The laptop comes with a 30GB drive. For a Windows PC, I'd go for 60GB: should I do the same here? This would make me have to order it online, which is a bit of a problem (I'm not often at home...).

Is generic vs. brand name a big deal when dealing with RAM?

This is an extremely subjective question...In an earlier thread I mentioned that I couldn't find memory below $150, but several members here found it for much less. However, much of the cheaper RAM is generic. Does it matter? Is generic vs. brand name a big deal when dealing with RAM?

Where can I get RAM for an old computer?

Looking to get some RAM for an older machine; the motherboard specs say it wants 168-pin 3.3 volt SDRAM; I'm wondering if this is still made (is this the same as some early PCxxx RAM?), or if I'm going to have to do some digging... If it's out of production, where could I find a 128-meg stick or two?

RAM Question

RAM question. PC100 ram comes in two flavors, low density where each chip on the stick is 16mb, and high density where each chip is 32mb. Someone told me that name brand laptops never use high density. This meshes with my experience, but what I want to know is: why? The high density stuff tends to cost half as much. [more inside]
