IWILL XP333 performs bad in memory bandwith..?

I just finished helping my friend building his new rig with Iwill XP333 using Duron 1GHZ (morgan). The system just run without hassles with Win2000 Advance Server. The problem is just how come the Sandra Memory Bandwidth Benchmarking shows that its bandwith is only a little bit better than KT266 with PC2100U CL2?... it's even much lower than SiS735 chipset and KT266A using the same memory setting (AMD760 is still the fastest one). Updating the Sandra and newest Iwill BIOS don't help it out

I don't think the ALi MAGIk chipset is the problem, I'm sure we have done something wrong with the BIOS setting, but the setting is kinda confusing us. We don't find the setting to increase the DRAM clock (100, 133, 150 or 166Mhz). FYI, my friend uses Kingmax DDR PC2700 which is the fastest memory for DDR SDRAM. I'm also wondering it's the CPU problem since all the benchmarks in Sandra use 1.4GHZ Athlon, but again I doubt it cause my ECS K7S5A perform extremely close to the Sis735 Sandra benchmark, eventhough I use Duron800 @1000 and generic DDR PC2100.

Anybody can help us out with this problem?... all inputs are welcome. Thx in advance.
 
the ALi Magik is the problem. It's just slower than the kt266a..even at pc2700.

Also why are you running Win2K advanced server??? That's going to kill performace in windows. If you actually need Win2k Advanced Server you really got the wrong setup (MB, CPU, memory)
 
The reason we use Win2000 Advance server is that my friend plan to use his new rig as a web server and a main rig in his home networking (with other 3 roomates). We'll try to uninstall the Win2000 and install Win98SE instead, to see whether it'll make any difference.

Yes, we have set the memory setting to 333mhz (166x2) but this doesn't help. I'll post the result ASAP. Thx guys
 
Unlock the Duron, lower the multiplier and raise the fsb, 1 of my rigs is a 1ghz@7x150=1050mhz@default voltage on a AK31A and it exceeds all the AMD chipsets in the benchies and is damn close to the P4 DDR platform. With a low enough multiplier you may be able to run the CPU@166FSB to stay synchronous with the memory and get some impressive numbers because as Furor stated "

<< using asynchronous mode sucks >>

"! BTW, my experience with the K7S5A is that 100/100 performs better than 100/133 but 146.6/146.6 was my best performing solution.
 


<< Update to the Jan 18th bios .. http://www.iwillusa.com and that should fix it ...... >>



Thanks for the advice,.. now we can smile and see the big difference in the memory bandwith benchmark after updating the BIOS with the version date above. Though it's not exactly as fast as the Sandra reference Alimagik chipset, we know that cpu Duron is slower than Athlon. Thank you everybody, we really do appreciate ....
 
You are comparing 100MHz FSB to benchmarks run on systems running 133MHz FSB. I have an Iwill XP333-R and the memory benchmarks in Sandra are excellent. I have a 1700+, so it is running at 133MHz FSB. If you lower the multiplier and raise the FSB (as DAPUNISHER said), you will see a big improvement.
 
i can only get my 8kha+ upto 162fsb stable. 256mb corsair xms2700. only bad thing is that the mobo thinks it's pc1600 @ 113mhz?
gainward gf3 - removed all pci cards also?????
