However, some of those are not PCI-X (as they are older) and thus do no necessarily support 100MHz or 133 MHz operation. I can't say that it'd work quite that easily with using system memory as emulated bulk storage (unless you're running certian flavors of UNIX). The idea of getting a RAM drive for a day-to-day system is still appealing; it'll just have to wait a while as my budget wouldn't be able to support it right now.

Oh, come on. What's $64,000 for a 64 GB system?

I remember having an older Windows utility for creating RAM drives, but that was back in the day, so I don't know about it's upper limit for allocation. I am pretty sure that they're out there.

I don't know of any UNIX utility that would actually create the RAM drive directly because it is technically not a mounted/mountable device.

So, unless you re-map the device map and configuration so that it can be read as one of the standard interfaces, I don't know whether that would even work in UNIX. (More specifically, Solaris/SunOS.) The only way that I can picture UNIX (Sun) systems being able to do it is if it were on a separate card like it is now, and then using OBP to assign the addres/path to the device. You'd still have your work cut out for you in trying to get the OS or anything to install/run in or off of it, but at least that's the idea.

Yeah...umm, maybe if my name were...say, Steve Saleen and the system was for the engineering department of my company?

Wait a second.

RAM via PCI? Sounds like realllllly heavy saturation to me. Wouldn't that actually slow down your computer?

Yes. See one of my previous posts in the same thread.

Now, if the RAM was running off of the HyperTransport bus, that's a different story.
