At a guess, I would say not necessarily so, as capturing video is probably more to do with graphics, cpu, and hard drive performance. I don't think that memory running at a reduced speed would be a big application killer.
I assume you bought your memory as a dual channel kit, so it should function ok, but some kits are better than others. I have had kit that don't run too well on my various systems, and usually I just have to 'loosen' the timings a bit, and ensure that they are running at the correct voltage, however it they were really bad, you would have stability problems.
I think Kingston KVR memory is 'value memory', which is not particularly high performance ram, but is a more generic ram for general usage. It is always worth getting decent ram that is approved for your motherboard by the motherboard manufacturer.
A lot of people leave their BIOS in default settings, relying on the BIOS to set memory speed and voltage (using the SPD setting), which is stored on the chip. You would really need your RAM part number, to look up on the Kingston website, to check the specifications of the ram. Free programs such as CPU-Z should be able to tell you this data too.
The memory voltage is important, and needs to be set correctly in the BIOS, a wrong setting here may prevent memory working in dual channel mode, especially if the BIOS has set the voltage to a pretty standard setting like 1.8 volts, when really it should be at 2.1 volts (
please never guess this voltage or change it in any way, if you don't know for sure what proper voltage is). However there are so many variables involved with RAM, it's would be way too complicated to do such a thing here. It is worth doing online research on how to tweak your ram to make it stable or work correctly in dual channel.
I can only give you an idea of what I mean when I say 'loosen' the timings. When you find out the specifications of your ram, it may be something like 2.1 volts 5-5-5-15 2T. Usually your BIOS will read this data and setting the ram timings. If your RAM sticks are not working well together, you may have to manually set these times to a more 'relaxed' setting. For example you might try 6-6-6-21 2T, this relaxation will give the ram more time to carry out the operations that it needs to do, and that might be enough to allow the memory sticks to work better together.
You may find that setting your BIOS to Optimised Defaults, or a Safe setting, will loosen those timings and do what you want it to do, but other settings will change (nothing to do with the memory), so you may not want do that. If your BIOS has the option to save the current settings as a profile for later retrieval, then use it, and backup the settings before tweaking,
or you could be left with a computer that doesn't boot. If you get stuck you can usually get into the BIOS and set the system defaults again, which will enable the PC to boot.
Tweaking the BIOS is not for everyone, do your research first before tackling anything that you are not sure about.
Sorry I cannot be more helpful, but RAM and RAM timings is a big subject, and everything that I have learned is from reading stuff online, and building all my own systems over the years. Even then, I have only probably just scratched the surface of the subject.
Good luck ...
