Are you in the DDR2 market and want a speedy kit at a good price? The kit we are looking at today have a modest DDR2-533 stock speed and fantastic 3-3-3 timings. They also turn out to be good overclockers, making them a good value.
These modules are meant to function at 1.9v, but I found at stock speed 1.8v was plenty. Once we started to work beyond stock speeds though, 1.9v became a necessity.
- 1# 267MHz – DDR2-533 (PC2-4300) @ 1.8v – 3-3-3-12 : 200FSB – CPU 2.8GHz
- 2# 267MHz – DDR2-533 (PC2-4300) @ 1.8v – 3-3-3-12 : 267FSB – CPU 3.74GHz
- 3# 292MHz – DDR2-584 (PC2-4700) @ 1.9v – 3-3-3-12 : 233FSB – CPU 3.29GHz
- 4# 300MHz – DDR2-600 (PC2-4800) @ 2.0v – 3-3-3-12 : 200FSB – CPU 2.8GHz
- 5# 312MHz – DDR2-625 (PC2-5000) @ 2.0v – 3-3-3-12 : 250FSB – CPU 3.50GHz
- 6# 334MHz – DDR2-667 (PC2-5300) @ 2.1v – 3-3-3-12 : 250FSB – CPU 3.50GHz
- 7# 334MHz – DDR2-667 (PC2-5300) @ 2.1v – 3-3-3-12 : 267FSB – CPU 3.74GHz
- 8# 352MHz – DDR2-704 (PC2-5600) @ 2.1v – 4-4-4-12 : 264FSB – CPU 3.69GHz
In order to distinguish a successful overclock, the settings must pass error free through test 5 and 8 of MemTest. In order to make sure the modules were not defective on arrival, 10 runs of MemTest were performed. Those tests were error free, so we were good to go with overclocking.
As you can see, I tried to retain the original timings as much as possible. The last setting was the only one were the timings had to be loosened, because my goal was to break the DDR2-700 barrier. As usual, the overclocking ability impressed me, considering OCZ stresses that these are ‘value’ modules. We gained an 85MHz boost while retaining a safe VDIMM.
