The answer is 'There are certain things even rats won't do.'
I suspect there are certain things that even software can't do. Does a sprinter carry a stop watch so they can measure their own time in the 100 yard dash? To be accurate you need a reference point and that can be very difficult for the UUT to do.
Simply stated I question the accuracy of the software, particularly where different architectures are used.

Running memtest86 around here is giving me some strange figures, and this is really to ask why. For those who don't know it, memtest86 is an 8k boot file which does a serious memory test on x86 based computers.
It also returns figures for memory speed for L1 cache, L2 cache, & main memory. These main memory speeds are my question. Here's what I got:
P1-233Mhz (I presume a 66 Mhz bus) 142 MB/S Intel 430 chipset K6/2-350Mhz 100 Mhz bus(pc100 ram) 127 MB/S SiS chipset k6/3-500Mhz 100 Mhz bus (pc100 ram) 130 MB/s Via Chipset P3 Coppermine -730Mhz 100 Mhz bus? 242 MB/S Intel 810 chipset (It's loaded with pc100 ram) AthlonXP-2.6Ghz 333 Mhz bus (?ddr RAM) 730 MB/S Via Chipset
Unless the Intel chipsets are feeding the ram twice as fast, I fail to see how these make sense. Particularly, how come Intel seems to get 242 MB/S when Via and SiS only get 130 MB/s? How come the humble p233 outsprints a k6-500? Which is real?
I am vague about the Intel stuff because the p3 was _given_ to me, and the p233 is an ex-ebay Industrial cpu card.
I gather there is some difference in the way clock speeds are measured between AMD and intel cpus. The Athlon was reported as 2.075 Mhz, whereas in fact it's a 2.6Ghz. I have seen BIOS detect it as both. (There was a BIOS revision on the Chaintech MB I have the Athlon in to correct the detected cpu speed).
Any ideas?
