Updating an old rdram dell
Right next to it there is a Corsair Dominator Air Flow memory cooler making sure that the beastly double-sided Rambus doesn’t overheat.When it does that, it may throttle down by switching individual Rambus devices or “chips” from “Active” to either “Nap” or “Sleep” states, slowing the RAM down. Actually, that cooler is hooked up to an onboard fan header labelled “Rambus fan”, so yeah.If you want all the details, and I mean all the details, get a copy of the best-selling book Upgrading and Repairing PCs, by Scott Mueller, published by Que.Ready Boost Microsoft introduced Ready Boost as part of Windows Vista.And then there is a second warning telling me, whether I’d really want to boot with more than 24 Rambus devices per channel (it’s 32 in my case, plus 4 for ECC, which is switched off though), which too is unsupported.Saying “y” once here will make the BIOS remember that choice until the next memory configuration change. Update 2: And here are two pictures of the completed Pentium 4 machine.They are actually quite bad, some issue with the exposure when using the flash.
However, at PC1066 speed it would limit the amount of devices to 48, resulting in a total of 1.5GB instead of 2GB, as the maximum device density supported is 32MB per device.
Maybe it’ll force PC800 on me (then I’d still get 2GB of memory) or it’ll cut me down to 1.5GB (then I’d still get PC1066 speed). Update: React OS didn’t like what I did there (BSOD), but it seems Windows XP is ok with it.
The systems BIOS warns me on POST, and asks me I’m running an unsupported memory configuration, and whether I’d really like to continue booting at PC1066 speed.
RAM holds Windows and the programs you're actually using, and Windows 7 wants more RAM than Windows XP, but is happy with what works for Vista (if not even slightly less).
As discussed in the early chapters of this book, Windows 7 can run with as little as 512MB of RAM and an 800MHz CPU, but it will run a bit slowly, and you'll find the experience somewhat unpleasant.
Now, if you're already running Windows 7 on a full-bore, state-of-the-art system, and your computer has a fast video accelerator, a couple of gigs of fast memory, and fast SATA disks, there isn't much more you can do to optimize its hardware.
