8GB vs 16GB

[Buckster]

thanks for the clarification

I'm debating for new build .. 16gb or put the difference in price (about 40-50 quid) towards a 2600k instead of a 2500k

Never.

Bill Gates "640K ought to be enough for anybody."

Depends what you want to run. If you run high demand software then then the 2600k would benefit but you would also probably need the extra RAM so its a bit of a catch 22 :S

I haved maxed out 6GB several times using some rendering in 3ds max, its doewsn't take much or particularly heavy scenes to use it all.

Personally I would but thats just me and my needs

I remember upgrading my 16MB of EDO memory to 32MB with matched pairs.

Good times.

I'm tempted to put 16gb into my PC upgrade which I'm currently ordering parts for. The only reason being that its a mATX build and the cooler looks like it's going to cover all 4 ram slots so if I ever wanted to increase the ram it will be pain.

At £40ish for another 8gb I'm having a hard time talking myself out of it, even though I doubt I'll get any benefit from it!

I remember doubling the memory of my Amiga a500 from 512k to a massive 1mb so I could play dungeon master.
I also remember upgrading my amiga 1200 to add 4mb of RAM (with a double speed 68020 processor) and an 80mb harddrive.

Seen a few people have spoken re windows addressable memory, yes for some reason theyve chosen to limit the amount of memory it will address, a 64 bit OS should be able to address 192gig but for some reason windows only allow this on ultimate and above

 

[Nightglow]

192GB , I'm happy with just my four slots filled with 16GB.

Would it be even possible to make 48GB sticks of memory to fill those four slots.

For Windows 7 64 bit it's 192GB on Professional, Enterprise and Utimate.

For Windows Vista 64 bit it's 128GB on Business, Enterprise and Ultimate.

Home Premium 64 bit is 16GB for Vista and Windows 7.

In theory a 64 bit operating system could access 16EB (exabytes) of RAM.

That a lot then? lol

 

[Liquiduk]

That a lot then? lol

The second byte after terra I believe or maybe third.... -.-

 

[Surveyor]

That a lot then? lol

16EB= 16,384PB = 16,777,216TB= 17,179,869,184GB

Yep, it's a lot

 

[hansp]

In theory, so can a 32bit OS.

 

[Surveyor]

In theory, so can a 32bit OS.

I say in theory because of the practicality of having 17,179,869,184GB of RAM.

I'll bite, show me how a 32 bit OS can access that much RAM.

 

[hansp]

PAE. It just cannot handle that much ram in the same efficient way as the 64bit OS can. But who cares about efficiency in theory.

 

[Surveyor]

PAE.

Thank you for taking the time to offer such a detailed explanation

I thought the theoretical limit using Physical Address Extension was something like 4PB or 4,194,304GB?

 

[hansp]

The theoretical limitation is the same as in 64bit mode, since the physical address structure is the same in both addressing modes.

 

[Surveyor]

The theoretical limitation is the same as in 64bit mode, since the physical address structure is the same in both addressing modes.

A link which shows that please.

Not gonna happen, this has been talked about many times before.
