If you are thinking of jumping onto the PC2-8000 bandwagon, there is surprisingly much more choice now than there was just two months ago. Like other PC2-8000 kits we have tested, A-Datas is seriously fast, but is it worth your hard earned cash?
3D Mark 01 is considered outdated for a good reason. It is. One great thing it’s still good for though, is seeing how your CPU overclock scales. I like to pay more attention to PC Mark though, since it’s benchmark is completely memory specific. Looking at the DDR2-1000 reports, the scaling is quite interesting.
- 5-5-5: 4840
- 4-4-4: 4877
- 4-4-3: 4915
I am impressed that adjusting the tRP made any real affect, but it actually made a 40 point difference in the score… the same difference as going from 5-5-5 to 4-4-4.
Super Pi, like 3D Mark 01 is good for seeing how your CPU overclock scales. The primary benefit is that it does just that… but quickly, especially if you only run the 1 Million method. Memory plays a big part in the results though. The tighter the timings, the faster the roundtrip for the data between your CPU and memory.
All of the previous results have been done using only the A-Data modules. For a comparison test, I took the recently reviewed VX2 to see how they fared. Both sets of modules used the exact same settings. The FSB stayed at a constant 250… only the memory frequency was increased. Here is a quick list of the used settings and voltages required:
- DDR2-667 (333MHz) 3-3-3-8 1.9v
- DDR2-750 (375MHz) 3-3-3-8 2.2v
- DDR2-833 (417MHz) 3-4-3-8 2.4v
- DDR2-1000 (500MHz) 4-4-4-8 2.3v
Interestingly enough, the A-Data modules cleaned up the DDR2-667 results, but were no match for the VX2 at the other settings. Why I find this somewhat humorous is because the Vitesta use more expensive chips, but seem to lack in the greater speeds.
