What we think

Undervolting

Going back to the Intel system, we can adjust the DRAM voltage in Windows by using the Turbo-V application. By running Prime95 and then dropping the voltage until failure sets in, we can determine just where the threshold of the LoVo modules is.

Impressively, they continued to pass the test until the memory juice was dialled down to 1.25V - the lowest we have seen for a DDR3-1,600MHz set.

Concluding thoughts

Kingston is looking to make some noise with the low-voltage DDR3 modules marketed under the LoVo banner. Our test modules are specified to run at 1,600MHz CL9 with an operating voltage of 1.35V, or 0.3V below many comparable kits.

Priced at equivalent levels to standard dual-channel kits in the US, the 4GB (2 x 2GB) LoVo set attracts a small premium in the UK. But is that premium worth it?

Our investigation on both Intel and AMD platforms shows that there is a slight reduction in power-draw when compared to memories guzzling 1.65V, and the effect is akin to using DDR3-1,280/1,333 kits with a JEDEC-approved 1.50V rating.

The benefit of the LoVo brand will be felt by people who are able to use a large number of modules in one system, thereby compounding the advantage we've seen from a kit consisting of two sticks. This is why low-power modules are especially suited to the workstation/server environment, where both power and cooling savings literally mount up. Indeed, although not certified for such use, putting three sets (six modules) into an X58/Core i7 platform would make sense for some power users.

Bottom line: the Kingston 4GB DDR3-1,600 CL9 LoVo 1.35V modules are seriously worth considering if you can purchase them for the same outlay as a comparable set that chews through 1.65V; there are no downsides for doing so.

The good

Decent speeds for low voltages
Small premium over regular DDR3 modules in the UK; none in the US

The not so good

The power-saving gains are minimal for a two-module kit

Idle power-draw is remarkably similar to Intel's, mainly because the Core i5 661's power-saving technology is sacrificed when adjusting the BCLK.

Could you test with something that has an extra RAM multiplier then, assuming this is the reason why you had to up BCLK ?
The kit ships with a recommended US etail price of $158, but is available from Newegg for $136, and its etail listing is on a par with regular modules (1.65V) with the same speed and latency characteristics. UK customers, often at the wrong end of a bargain, will pay around £125 for the same set.

$158 = £102.70
+ 17.5% VAT = £120.67

$136 = £88.40 @ $1:£0.65
+ 17.5% VAT = £103.87

Retailers here won't offer the same deals. :(
So basically what Hexus is saying is that, according to the results, Kingston used up more resources in marketing and design than will be saved through green-concious users buying these over standard modules.

Good work Kingston.

We wanted to take a look at the memory with an Intel chip that will ship with a number of mid-range systems.

An Extreme Edition chip will allow DDR3-1,600 memory at the default BCLK, and we'll add those results in shortly, seeing as you have requested them. :)

Marketing.. money well spent if they get higher sales. Design.. doubt it - they will have just binned existing chips.
