Albatron kt600 low in memory band with test ?

[vanln]

I got a combo albatron kt600/2600 + amd . I o/c to 3000+ ( 12.5 x 175) . The sisoftware memory bandwith test is so low compare with my old MSI KT333 . The test read only 1850 (albatron) vs 2820 ( MSI KT333) . I use the same memory and the same CPU for test . My old MSI mobo seem to o/c better and more stable . It could run well at 12.5x179 without a crash . I install the latest via 4 in one download from albatron web . Same thing happen
Did i do some thing wrong or this is the nature of the mobo?
I test a pair of centon dual channel ( PC3200) is gain to 2250
with PNY (PC2700) only 1850

Use the DOS application CACHEMEM.EXE to measure actual throughput and latency. Everything that runs in Windows is no better than estimation.

It might very well be that on these overclocked settings, the RAM timings are tuned way down. Higher clock doesn't always translate to higher performance ...
