I'm gathering a small database of memory latency scores for any and all systems. I have a few already, but I'm looking for more. Basically I'm trying to get as many examples of real-world latency tests as possible. This program tests L1, L2 and RAM latency, but I'm mostly interested in RAM. If you're up for it, please download the program below and run it. It generates a small text file, please attach that to an email to the address also below.
The results are displayed in size of requested reads and clock cycles of latency. Using an Athlon XP as an example, 0-128k reads would be from the L1, 129-256k reads are from the L2, and everything above that is from the RAM. Hopefully that makes sense.
I'll be writing an article based on these results and other info. Also, if you have any other programs to test latency, let me know. I'm always on the lookout for stuff like that.
Info to include in email:
CPU and clockspeed
Motherboard and chipset
RAM and clockspeed
Relevant BIOS settings
Again, I'm interested in scores from any system with SDRAM, DDR-SDRAM or RDRAM, OCed or stock.
The more people I get doing this, the better. No need to reply to this thread to tell me you'll do it, just email away. Feel free to ask questions, of course.
Program:
http://personalwebs.myriad.net/roelof/setispy/latency2.exe (again, it creates a small text file with the output which is what I'm interested in)
I also mirrored it at home here:

Thanks everyone!
