At first I started to think the MHz value is just multiplied by 2 to get the data transfer rate of RDRAM, but then in the same article they mention certain RDRAM chips don't follow that rule. Namely on, PC600 RDRAM runs at 266 MHZ, while PC800 RDRAM runs at 400MHZ.
PC800 RDRAM runs at a clock of 400 MHz and it uses a DDR-way of transporting the data. Thus the 16 bit or 2 Byte data are transported at 800 MHz, explaining the '800' in PC800. ....if you think that PC600 stands for 300 MHz you're dead wrong. PC600 RDRAM runs at 266 MHz
So, what's the correct formula for calculating transfer rate? Multiplying by 2 seems accurate in some cases but not all,
-
They're just not written very clearly and some of them have contradictory information, unlike crucial's FAQ on DDR. The best I've found is the reason for why RDRAM is no longer used, mainly a price fixing scheme from the DDR manufacturers in the early 2000's.

They don't say it directly.
-
Yeah, I've read that. That source taken with other sources isn't exactly clear on RDRAMs transfer rate. So, again how would I calculate the MT of RDRAM?
-
Yeah, it looks like I am doing that. I wish manufacturers actually listed units on their products. Thanks for the help.
How would I calculate the MT of RDRAM? I don't believe it is dual channel.

I know my stick of RAM has an 800MHz frequency, but Speccy only lists 400 MHz. I take it it's just halving the number. So, if I have DDR3 do I multiply the MHz by 3, and 4 for DDR4? What about RDRAM? (One of my systems has some.) Is RDRAM just the number listed?

minixp tells me to boot up in another os. I never entered the boot cycle for 2k, so the latest version of Speccy should be able to profile the system. The Minixp mentions booting with another os on the disk, when I try to run Speccy, so which option is that? I'm trying to completely circumvent the installed OS, so whatever version of speccy should run.
-
I've gotten an older version to run, but it locks up before completing the profiling. (I think it's the system and not speccy. The system is a bit wonky.) I just need to figure out where it is on the CD, and run it without entering the OS present on the system.

How can I go about accessing Speccy on the bootCD? I've gone into miniWindowsXP, found it and it told me to boot up xp or later. When I select the boot xp option the systems default operating system (Windows 2000 Advanced Server) just boots up, and I can access Speccy from there, but it freezes my system. I'm trying to check the system out, without getting complications the possibly malfunctioning os. So, where could I find speccy on the disk?
Need help interpreting RAM frequency results from Speccy.

I'm reselling RAM and want to make sure I have the right specs listed.
