Do you really get much benefit out of overclocking a Tualatin board from 1.4 to 1.6 GHz?
Made a big difference in my system. The overclock made many of my games run noticeably faster, and it even made 720p AVC playback completely smooth. I think the increased bus speed is what did it; P3's SDR FSB always seemed to be a major bottleneck. Tualatin would've been one heck of a chip with a DDR bus.
Edit: Then again, I use a TUV4X (VIA) board. Perhaps overclocking an i815 makes less of a difference.
I am currently setting up a dual Tualatin system to replace my aging dual Coppermine 850. This particular dual Tualatin board uses DDR RAM. The best it will handle is DDR266 with CL2, which is PC2100 CL2, or PC2700 CL2.5 (more common, and also works as PC2100 at CL2). Using Cachechk7, I get 744 MB/s read and 395 MB/s write. This board cannot be overclocked beyond a 133 MHz FSB, so it maxed at 1.4 GHz Tualatin III-S, although the memory data rate is effectively 266 MHz w/CL2, non-ECC.
By way of comparison, a dual Tualatin PIII-S 1.4 GHz with standard PC133 SDRAM and an Intel ServerWorks ServerSet III LE gets 696 MB/s read and 397 MB/s write with Cachechk7. The ServerSet III LE, though, is using buffered ECC RAM, so some decreased performance is expected.
I have not yet bompared the two with Windows benchmarks. 696 MB/s to 744 MB/s is not exactly something to be wowed by, but at least it is something. I am curious what cachechk7 read/write values do you get with your 1.6 GHz overclocked system? CL2, CL2.5, or CL3?
You can use the command: "cachechk -d -t4" for a quick memory read test
and the command: "cachechk -d -w -t8" for a quick memory write test.
Plan your life wisely, you'll be dead before you know it.
