Corsair Dominator GT 1600MHz AM3 Review



Given the results, we're happy to report that the Dominator GT DDR3-1600 is a fantastic set of memory. It accompanied our Phenom II X6 1090T perfectly, showing a small but notable lead over cheaper CAS9 1600MHz and 1333MHz sets. It's tall heatsinks serve their purpose and the additional active cooler (while loud) ensures that your new modules never catch a fever.

However I do believe that it's important to mention our AM3 overclocking woes once again. Even though we proved that Dominator GT RAM are capable at much higher frequencies, this was not possible on our AMD testbed. While our sample processors aren't exactly the sharpest tools in the shed, there are many in circulation that perform similarly. As such you will want to be certain that your Phenom II processor has a strong memory controller before investing in premium RAM, which will otherwise be wasted.

Our results showed that at the same frequency, a CAS9 set is just a smidgen behind our CAS7 Dominator GT's, and it's possible to find these for almost £60 less. Ultimately our conclusion returns to the reasons behind investing in a Socket AM3 system in the first place. Given the value for money nature of Socket AM3, it really is a contradiction to invest in expensive memory that (unless overclocked) will only offer a fractional performance difference over cheaper sets. Thinking laterally, the £60 premium invested in Dominator GTs could go towards things that may offer a more noticeable difference in performance; choosing Core i7 over Phenom II, a Radeon HD 5850 over a HD 5830, perhaps another HDD for RAID0 or a new sound card?

As far as Corsair and the Dominator GT is concerned, kudos are in order for developing this set of memory. As our Core i3 testbed indicates, if your processor's memory controller is up to the task then there are performance gains to be had. If it's fast RAM that you want, then this could be it.

The Good
- Overclocks well
- Optional cooler is effective
- Excellent styling & aesthetics.

The Mediocre
- £60 premium over non Dominator GT equivalent
- Optional cooler is far from quiet.

The Bad
- None.

Thanks to Corsair for the sample today, you can discuss this review in our forums.

You can just tell that has been designed for recent ROG boards

Aye if the AMD's dont like high speed ram or at least overclocking the ram for high speeds then low latency just makes alot of sense.Quote

this ram is could boost your systems gaming performance specially for AMD platforms which suffer when compared to Intel's platforms.Quote

Should the latency numbers be higher or lower? What do they mean?Quote

The latency numbers should be lower because the AMD processor memory controller can’t deal with high speed memory so the only thing that will improve performance is to lower the memory latency which means it will respond in less time to orders that come from the CPU so the lower the better. I have tried low latency memory on a 965 AMD CPU and it did improve the performance.
