Buffalo PC3700 DDR

 

Test Environment :

• Epox 8RDA3+

• AMD AXP2400+

• Tyan Radeon 9700Pro

• 2 x 256M Buffalo PC3700

• CPU Voltage : 1.75v

• AGP : 1.7v

• DIMM : 2.9v

• VDD : 1.8v

As the ram is rated at CAS 3, we first tried it at CAS 3, 8-4-4 at 10x200MHz FSB. The system did not boot. We tuned it down to CAS 3, 10-5-5 and run at 8x200MHz FSB. The system still refused to boot. From these observations, it seems that the BIOS never catered for CAS 3 RAM. We need some confirmation from EPoX on this. Lowering it to CAS 2.5, 6-3-3 works well and the system has no problems booting at all.

To test the aggressive timings, we set our AXP2400+ to run at 8 x 223MHz at CAS 2, 5-2-2. It booted up well but it is not stable. We lowered the FSB to around 230MHz, SuperPI passes but 3DMark2003 fails. We tuned down the FSB to around 210MHz, SuperPI is OK and 3DMark2003 runs smoothly.

Below are the scores :
