RAM Speed according to Memtest86+
Here are some speed results for RAM according to Memtest86+ on some machines that I have run. Note that the reported speed varies between runs by a few percent.
| Compaq Athlon 1GHz PC133 RAM (3 DIMMs) | 219MB/s |
| Compaq P3-800MHz PC133 RAM (1 DIMM) | 270MB/s |
| Compaq P3-800MHz PC133 RAM (3 DIMMs, 2*128 + 256) | 240MB/s |
| Compaq P4 1.5GHz PC133 RAM (3 DIMMs) | 486MB/s |
| Compaq P4 1.5GHz PC133 RAM (1 or 2 DIMMs) | 490MB/s |
| HP Celeron 1.8GHz PC2100/DDR266 (1 DIMM) | 824MB/s |
| HP Celeron 2.4GHz PC2100/DDR266 RAM (2 DIMMs) | 984MB/s |
| Celeron D (32bit) 2.93GHz PC2400/DDR300 PC3200 RAM | 1,140MB/s |
| HP Celeron 2.4GHz PC2700/DDR333 RAM (2 DIMMs) | 1,027MB/s |
| HP Celeron 2.4GHz PC2700/DDR333 RAM (2 DIMMs) | 1,375MB/s |
| Dell PowerEdge T105 Dual-core Opteron 1212 (2GHz) single DDR2-667 ECC RAM | 1,670MB/s |
| Dell PowerEdge T105 Dual-core Opteron 1212 (2GHz) pair of DDR2-667 ECC RAM | 1,826MB/s |
| NEC Pentium D 2.8GHz DDR533 (paired DIMMS) | 2,600MB/s |
| NEC Pentium D 2.8GHz DDR 533 (unpaired DIMMS) | 1,600MB/s |
| NEC Pentium E2160 1.8GHz DDR663 (single DIMM) | 11,700MB/s |
DDR266 theoretically can do 2100MB/s, but I’ve only seen it do 984MB/s (with two DIMMs).


HP BL35p AMD Opteron 2.4Ghz DDR400, 1648 MB/s
