How do I change my voltages on my ram with a asus z87 pro?

I bought this ram like five months ago, and just noticed that the voltage is 1.65, and it's only 1600mhz.

I saw this review on newegg, and I would like to do this config on my ram as well. Is 8-8-8-24 faster than 9-9-9-28?

Pros: Works as advertised. I have an Asus Maximus Hero board which automatically set the voltage at 1.5v and the timing at 9-9-9-28. I have it at 1.65v and 8-8-8-24 now.
Cons: As the others have said, this memory gets hot especially when you try to overclock it. I bought this memory with the hope of o.c.'ing it but it looks like i'll just be staying at 1600mhz.

Other Thoughts: Overall good memory. It'd be nice if Kingston included the preferred timings.

The performance of the DDR3 memory depends on two factors:
a) Timings (lower is better), and
b) Frequency (higher is better)

Having said that, 1600MHz CAS9 which you have at default is rarely a bottleneck anyway so getting better performance is unlikely to benefit you.

I recommend you:
a) Keep the recommended settings, and
b) run a full pass with memtest

Another issue is that memory instability isn't always obvious and can result in errors over time that corrupt your data so again I strongly urge to keep the default settings.

The problem is that the ram modules heat up too much. :/

*There are memory coolers if you really think you need them. I'm guessing this Corsair fits all but do a little research:

System RAM is always too hot to touch, so unless the temperature is way above what it should be I don't see a problem.

All that really matters is that it works, so if it passes MEMTEST (again use default settings) you are okay.

Airflow is obviously important to keep the temperature down. Some people with liquid cooling can have overheating issues on the CPU voltage components and their DDR3 memory would run hotter as well likely. This is the reason some experts recommend reversing the radiator fans to INTAKE to blow more air over the CPU/RAM area. It's also my main ISSUE against liquid cooling.

The way I'd approach liquid cooling for current PC's would be to use only motherboards with the liquid cooling run through the CPU voltage components, and also have a single large, quiet fan to cool all of the DDR3 slots at once (small fans can BUZZ annoyingly).

Make sure you have adequate airflow in the case:
1) Intake fan or fans (bottom front)
2) top/top-rear fan or fans (exhaust usually)

My CPU and case fans are all controlled from my motherboard with the Asus software (in my case Thermal Radar; yours may be different). Each fan has its own profile such as 50% speed until 40degC then ramp up.

Requiring 1.65 for 1600 is sort of ridiculous, and can b indicative of using weak ICs (memory chips), 1.65 is more appropriate for 2133 and up. Have played with a number of Kingston sets and haven't found many with OC headroom, I'd prob stick to 1600/9 or if stable at 1600/8 might try lowering voltage to 1.6, 1.575 or so
