Would it be feesable to create a ram drive big enough to put the system partition on? If so how would one go about it.

i read about this a while ago.

look at the logistics...
first find a decent board with 4 ddr slots...
so thats 2gig of system ram realistically.

next you need a program that makes ram drives big enough. i know the old ramdrv program and the windows one doesnt cut it. they are limited to megabytes, allthough from all reports there are programs that can do far bigger ones around (dont ask me where)

and finally you need a slimmed down OS that will take up less than 1.5Gig. think that rules out winXP hahahaha.

you would also need some bios supported suspend to ram system... and a UPS to be safe/ otherwise the system on ramdrive would be useless as it would be empty everytime u started up from cold.

hmmmm
im sure there are other issues (i..e how to get it to recognise the OS to boot etc)
but thinking is terribly hard :smile:

I don't know much about it. But I thought you could make a partition and format it just like another drive. and then if you had to shut down your system it copied all the info to a hdd partition and then when you started the system again it moved it back into the ram drive. My board supports 3gigs I only have one right now. I'm thinking about adding 2 more and making the system partition a ramdrive. Of course I'll probably never do and just fantasize about it.

What about that HyperOS system. Thats supposed to do something with the ram or something, isn't it? Can't be bothered to look it up myself.

The Good Old DOS Ram Drive had a 32MB limit.

If you moved your entire OS from hd to ram every time you booted up, it'd make the boot process take a while. (2 gigs at 30 megs/second (that's being really generous too) = well over a minute of copy time. Then you have to actually boot up (I think that'd only take a few seconds after that though).

I saw a snazzy device the other day, it is a pci card that lets you plug ram into it, you can get 6 gigs inside and windows detects as a hard drive, fast as hell but when you reboot it is erased as is the nature of ram... I will try to find a link it would be able to do what you ask

now if you could make it FLASH ram.... hmmm
would be useful!

or possibly suspend to ram.

Dude, that's not expensive at all! It's only a thousand bucks. Sh!t, I may consider it w/ my next comp. I can feel it now- Dual hammers at 5GHz, 2GB QDR, 10 gig ram drive, serial ata raid, Quadro 5,6, or 7. Drool. Oh and a 19" LCD of course w/ FFD. Heheh, think it'll be nice?

Actually, I was looking for someone to design a SCSI or IDE interface card for 16 SDRAM slots, with provisions for a battery backup. I'm a designer and could package the whole thing in an atractive case.

I hear the ones that use flash memory have very poor write time.

Hmm.. I was looking for something a little cheaper than a SSD. I'll keep looking into it. Who knows maybe i'll find something.

I had the idea for something like that a few years back. At the time (which was a few years back), the plan had been to make it an external SCSI device that had 1GB of PC133, a built-in processor for control, and a built in 2GB HD for backups and restoration on boot up (as well as for controller's OS and settings.)

I didn't have a battery backup in mind though. I just figured that you'd write an NT service (or *nix daemon, or whatever) to tell the controller to perform a backup to it's internal HD on system shutdown, and it'd restore itself from the HD when the PC started up. If your PC crashed, you'd be screwed though.

Now a days though, I bet you could design a special box using 10GB of those 2ns DDR modules and uniquely-designed memory controllers and a specially built CPU designed around the memory interfaces used by graphics cards. I'd still prefer to use it as an external SCSI drive myself.

It also reminds me of my AGP Linked-List card. Though that's probably just a wasted concept as it only makes sense to software engineers.

Now that companies have recognized the market potential of SSDs it won't be long before someone builds a PCI-X card with 20+ 2GB DDRII DIMMs in it.

Yeah, what's rthe deal w/ PCI-X, when r we to see it on mobos?

Won't be long as in by Christmas this year, or won't be long as in two years?

Hmm ... for that matter, I haven't even heard of a PCI-X motherboard actually existing yet. Has anyone made them?

Maybe they will implement it into enthusiast desktop PCs when the Hammer is out (not the first chipsets... but the second generation or something).

I'm wishing for PCI-X 2.0 (266-533Mhz) in Hammers.

You wouldn't need anything as fast as 2ns, even the old 60ns stuff would be faster than the drive interface!

DDRII will be faster than PCI-X. 6ns SDR would be more than adequate for that interface at current speeds, and 3.5ns DDRII would work for the eventual 533MHz PCI-X 2.0 interface.
