48GB = 49,152MB
49GB = 49 x 1024 = 50176MB
What you said makes no sense.
It's classed and sold as a "48GB kit" - there are 12 x 4GB DIMMs.
But since 1GB is not 1,000MB, it's 1024MB, this actually makes a large difference when we get beyond small numbers. The 4GB DIMMs are actually 4,096MB in size - technically a 4.1GB DIMM if we round up.
So, 12 x 4096MB = 49,152MB or 49GB.
I think he is referring to SI standard metric gigabytes so 49GB would be 49,000,000,000 bytes. But I thought that memory and cache generally assumes a binary gigabyte (or gebibyte or what ever stupid name). The operating system would report this as 48GB.
I think they mean us to take it in the way below
Most people think a Gigabyte is 1000 Megabytes and this is generally accepted (this is the scale that Hard drive manufacturers use) in everyday life
A "true" Gigabyte is 1024 Megabytes, which is the standard that RAM manufactureres use
Don't round up, don't try to take a value that is base 2 (2^10) and turn it into base 10 (10^3)... it doesn't work. Just call it a 48GB kit, not "49GB of memory"... only hard drive manufacturers try the base 10 from base 2 trick, and it's annoying. You don't get "6.2GB" of memory from a 6GB setup...
Actually the proper method of representing is 49GB of RAM out of a 48GiB RAM kit.
I'M BUYING 24GB RAM KIT!!!
(I'm not really) I just thought I'd say so as I was looking for someone to say similar yet everyone is quibbling over what is a true gigabyte. ....yawns.
You can't mix and match a GB being 1000 or 1024 MBs! Make you're mind up and stick with it!
4x1000x12 = 48000 => 48000 / 1000 = 48GB
4x1024x12 = 49152 => 49152 / 1024 = 48GB
4x1024x12 = 49152 => 49152 / 1000 = 49GB!
Thus, it's always 48GB no matter what measure you use - so long as you're consistent!
If you work it out in bytes, which we all know are 1,024 and/or 1,000 to a KB, then it's actually 51,539,607,552 bytes, which is 51.5GB!!!!!!!!!!!1!one!!onethousandonehundredandeleven
This is the correct usage of base 2 vs. base 10. Reporters, take note, and use the correct GB or GiB when necessary. However, this article should have stated '48GiB of memory' in the title - you incite a lot of confusion as typically writing '49GB' will garner lots of negative attention. Stick to a normal factor 2 to reduce the backlash, and use the appropriate units.
Yawn, tittie Yawn, tittie Yawn Yawn YAWN!
Nice article though, shame about the anal posts above!
No it isn't, you're mixing units again, or assuming a MB as a base unit rather than a byte. 48GiB = 51.5GB.
wooohoo for bigger memory! it's about time! i had been at stand still with my memory size since 2007.
pedants beware bindi will eat your brains, 48GB 49GB, who cares at that amount, its insane
It's 49,152 Megabytes, which equals 48 Gigabytes at the correct 1,024 measurement or 49Gb at the incorrect 1,000 measurement. So stating 49Gb of memory in the title is incorrect imo.
Anyway, epic achievement. I worry to think of the scale of the things the guys creating if he needs that much RAM!

bauul, Gb =/= GB fyi
Is 49GB enough for Crysis?
