RAM is faster mate

Okay, I really phrased the question badly
I meant it to mean How is RAM faster than an SSD. DuckieHo pretty much nailed it on the head

How about Ram's speed is measures in nanoseconds, while ssd's speeds like hdd's are measure in milliseconds.

thats millionths of a second compared to thousandths of a second, a couple of

magnitudes or so in difference there.

Triple Channel DDR3-1600 would be:
200 * 4 * 2 * (64 * 3) / 8 = 38,400 MB/s theortical peak.

I know it's a really old thread but that's wrong calculation. I don't see why 64 should be multiplied by 3. The 3 in DDR3 is only as significant as a version number.

HTH!

You necroed an old thread. It is multiplied by three because the question was specific to triple channel memory, which was common on socket 1366 when this thread was made. A long time ago.

wink.gif dead things are fun !

Just curious, why isn't 3-channel common now? 38GBps sounds an awful lot for even 2015 !

Interesting question. And after reading this thread, I have another question...

On MSI's X99 boards they provide a utility to create a ram disk out of your DDR4 memory. The chipset supports up to 128gb of memory.

Does this mean (in theory) you could partition 64gb of your super fast DDR4 ram for a SUPER fast SSD?

sure. but it's not as useful as it sounds. Hdds are fast enough for media and ssds are fast enough for games since the load times are only a handful of seconds anyways. Steam can be dragged to a ramdrive but the only improvement I've seen is very short load times. I just tossed a second 840evo into raid 0 and ran a comparison. 1. hdd, 2. 2 raid 0 hdds, 3. rog raidr, 4. 2 840evo raid 0, 5. ramdrive @ 2400. You can see the ramdrive is ridiculous, but how much would a typical user benefit? I use mine for temp files @ to offload some usage from the rog raidr.
