A-DATA Vitesta DDR2 667 Memory Modules (2 x 512MB)

A-DATA Vitesta DDR2 667 Memory Modules (2 x 512MB)Thanks to our friends at A-DATA we are once again having the privilege to review yet another product and this time it’s some of A-DATA’s top end stuff!

These modules are one of the fastest sticks available from A-DATA and as you can tell from the pictures below their clear packaging and appearance tries to show this.

About A-DATA:

“Founded in May, 2001 by Chairman and CEO Mr. Simon Chen, A-DATA Technology Co., Ltd. has quickly risen to become one of the world’s largest memory and flash product providers. At the beginning, with DRAM modules as the major product line, A-DATA’s mission was to become “The Global Leading Brand of Memory Products.” Later on, recognizing the market’s trend, A-DATA diversified its product portfolio to include Flash peripherals and multimedia solutions. Capitalizing on the strong growth of DRAM memory and flash related products in the market, based on DRAMeXchange 2006 and iSuppli 2006 reports, A-DATA ranks second in the world for DRAM Modules and fourth for Flash Disks respectively.”

Similar to what we’ve seen on Mushkin’s Redline sticks the Vitesta’s heat spreaders are a distinct red, held on by two clips and quite securely too. Since we’ve mentioned Mushkin we may as well tell you we’ll be comparing these modules to some Mushkin sticks in the same class which should be interesting so read on. In case your wondering why these modules are called Vitesta there’s some little history printed on the small card in the package which reads “The brand name of Vitesta is incorporated with “Vitesse” whose meaning is “Speed” in French and “ta” which is adopted from “Data”.” So there you have it. That’s how the name has come to exist.

Testing & Performance
For testing we used SiSoft Sandra 2007 on the following system:

Gigabyte GA-8I945P motherboard
Intel Pentium D Processor
eVGA e-GeForce 7800 GTX video card
A-DATA Vitesta DDR2 667
Seagate Barracuda 7200RPM 16MB Cache
Antec Phantom 500 – 500Watts power supply

Results are compared with Mushkin PC2-5400


The above results show us that the Vitesta sticks are indeed a slight bit faster than the Mushkin though we weren’t expecting that so this is somewhat pleasing.


Unfortunately the modules didn’t fair too well when working in dual channel mode as you can see from the results above there is quite a bit of slowdown. That’s the sacrifice made when in dual channel.

However using both modules without any prior knowledge of its capabilities doesn’t really show enough difference from the Mushkin modules, the benchmarks were able to show us something but that something is a small margin. Hardcore gamers will notice the difference and will care much about these results but other than that the 667 DDR2 Vitestas seem to be quite a reliable and pleasant memory modules.


Clearly we see the Vitesta modules leading the way here which is excellent. We didn’t expect the Mushkin sticks to fall behind so much but they did. The good thing about SuperPi is it’s extremely accurate too.

Let’s have a look at some of the results of overclocking these sticks:


Stable or what? We’ve managed to up the FSB to 240 and the sticks seem to cope absolutely fine even after upping the voltage on the memory alone! This is some great news for anyone planning to overlock these sticks. From it’s stock level however if you look carefully at the above results and the non-overclocked ones you can see there is virtually no difference from the extra 20 FSB for some very strange bizarre reason. This was about as far as we could get with these modules on our board at least. They wouldn’t boot up windows if gone anyway past 240 FSB. We didn’t notice any problems even after trying to use the BurnIn tests which SiSoft Sandra 2007 offers.

We would of liked to see a better stock timing because these modules are capable of a lot more once overclocked. We managed to get tight timings and the sticks seemed to do absolutely fine. If you’re looking into building a new system but have a strict budget then the Vitesta DDR2 667 RAM is for you. It’s not the fastest of the fastest but it’s got fantastic reliability and at great value with performance to boot!


  • Good heatspreaders
  • Fairly overclockable
  • Incredibly reliable
  • Great value


  • Unnecessary stock timings
