Memory issues PC2700

Okay, majore memory issues

System:
Asus p4s333-M motherboard
p4 1.6A northwood (oc'd to 2136)
cpu FSB/pci ratio 133/33
cpu/mem freq ratio 4:3
2x256 KingMax PC2700 (DDR333MHz) memory

SDRAM configuration (default based on ram)
Cas latency 2T
Ras to Cas 2T
Ras % time 2T
Ras active time 5T

My Bandwith benchmarks from Sandra are HORRIBLE

1445 MB/sec for both tests

Reference system p4 1.6 with PC2100 memory is over 2000 MB/s I should be WAY above that with PC2700

Any help greatly appreciated
Thanks

Anyone have ANY ideas what's going on?

Welcome to Overclockers.com

The 4:3 setting means your ram is running at 100 MHz and your FSB is at 133. Try the 1:1 setting and your scores will go up a lot. If you get bios version 1.05 you can even run your ram faster at 4:5 even over 133 FSB. I was getting scores around what you are getting with the same board and 4:3 divisor. At 1:1 I got around 2200 MB/sec 222 timing and with 4:5 divisor 2.5,3,3 timings I get 2700 MB/sec! At 4:5 and 145 FSB my ram is at 181 MHz so I had to run slower timings. I just ordered some PC3000 Mushkin ram hoping it will work at 181 MHz with fastest timings.
