A-Data Vitesta Extreme Edition DDR2 800MHz review

Page 4 - Overclocking and tests with 3DMark Vantage

A-Data Vitesta series are on the market from a very long time. Those A-Data memory modules that come with guaranteed low timings and/or high working frequencies have been sold under Vitesta trade mark for years. They are interesting to overclockers because most of the time they have special chips, better cooling and potential to reach higher frequencies. Before we begin the tests, we wanted to see how high can the performance go for A-Data Vitesta DDR2-800 Extreme Edition, they looked promising. It was only later that we found out our expectations are not only met, they are exceeded by far.

The first FSB step that we tried was a little high, 1066MHz efective (the CPU frequency, remained the same, as well as FSB (333MHz), we only changed FSB:Memory delimeters), with timings 5-5-5-18 and voltage 2.1V - we didn't really expect success, but the memory ran nicely. Later we decreased the timings to 5-5-5-12 and lowered the voltage to 2V, where the RAM remained stable.

Soon after we did not more than 2 unsuccessful tries before we stabilized the memory at the staggering for the price 1111Mhz with timings 5-5-5-15 and 2.1V. So to make things interesting we included the following in the test:

• A-Data Vitesta DDR2 800MHz 2x1GB @ 800MHz 4-4-4-12 (default)
• A-Data Vitesta DDR2 800MHz 2x1GB @ 1066MHz 5-5-5-12
• A-Data Vitesta DDR2 800MHz 2x1GB @ 1113MHz 5-5-5-15
• A-Data mainstream DDR2 800MHz 2x1GB 5-5-5-15 (default)
• A-Data mainstream DDR2 800MHz 2x2GB 5-5-5-18 (default)

3DMark Vantage

We don't think there's anything that we haven't said about the popular DirectX 10 test from Futuremark, so let's just get down to analyzing the results:

The interesting thing in this instance is that more memory doesn't affect the test, but it's a fact that higher frequency didn't affect the tests almost at all (a difference of under 1% can come from test to test).

Next, we'll do few more synthetic tests, and after that we'll play some interesting games to see if low latency memory gives you some extra FPS.
