Testbed and Methods
So, we’ve got three overclocker-friendly kits of DDR2 memory at our disposal and despite them having different characteristics their manufacturers each claim its particular product to be the optimal choice. To compare them justly, we will test them to find what frequencies and at what timings these memory kits support.
We assembled the following testbed:
- Processor: Intel Pentium 4 520J (2.8GHz, 1MB L2, Prescott D0);
- Mainboard: ASUS P5WD2 Premium (LGA775, Intel 955X);
- Memory modules:
- Corsair TWIN2X1024A-5400UL;
- Mushkin XP2-6400 DDR2;
- OCZ DDR2 PC2-8000 Platinum Enhanced Latency Dual Channel;
- Graphics card: PowerColor RADEON X800 XT (PCI Express x16);
- Hard disk drive: Maxtor MaXLine III 250GB (Serial ATA-150);
- Operating system: Microsoft Windows XP Professional SP2.
Mainboard’s BIOS settings:
- Performance Mode: Auto;
- HyperPath3: Enabled.
Most of the tests were performed at 2.1V memory voltage. This is the voltage all the tested modules are rated for.
