Why Do I Need Higher Mhz Memory?

[TheCasaNova]

in what scenario would i need really fast memory for. the dominater ram by corsair has about 2400MHz but how would this make it  better than 1800MHz memory.

Pretty sure there isn't much real world point. I know APU's can get some gain from faster RAM, but for most everyday tasks it will make no difference. It isn't a big deal for gaming, and for every day tasks it means nothing. Im sure there are scientific programs out there where it would help (maybe?). Only real benefit is to help an overclock, sometimes the lowest RAM multiplier on a motherboard can be above the RAMs rated speed if your going for some crazy clock speed, although I feel like this was for old Front Side Bus overclocking (newest board I have really OCed is my x58 i7 920, and I did run into this issue in a way).

In theory, very highly clocked memory would assist onboard graphics and APUs greatly, but in real world applications, if you're able to afford memory clocked that high, you would likely (99.9%) be running a dedicated GPU with it's own ram.

So, no, you do not need higher MHz memory.

If you are wanting to buy new memory then sure its worth future proofing your system, that's if you can afford faster ram, usually its the cost that limits us to how fast a system we have.

 

you might not see much benifit now but it will sure futureproof it.

 

a few years ago i got some Dominator GT 2000 o/c edition ram which was very expensive at the time and still is today, it was way over the top, but 3 years later i still have the same ram modules and they run perfect.

 

computer technology and speeds change so fast, and as far as i know DDR4 isn't out yet, so if you can afford to buy the best and fastest you can get at the time of build./ upgrade.

There are few instances where faster memory will benefit you noticeably. One of the rare examples is when using your RAM as a drive, and for some benchmarks.

I have the gigabyte ga-z77x-d3h mainboard. On the website it sais it supports up to 1600mhz ram and then up to 2800(OC)

In the list of supported modules there are several modules that exceed the 1600 limit.

Hypothetically, if I'd go for the fastest supported RAM possible, would that somehow influence how far I can OC my CPU?

High-clocked memory benefited AMD architecture in the past, especially in games but recently, the APU Trinity processors are also in need of good memory speeds.

1600mhz ram is pretty good for gaming. You will only benefit the ram performance on AMD cpu. You won't really notice a difference in ram in Intel systems except in benchmarks.

Pretty sure it will make no difference. Since sandy and ivy use multiplier overclocking instead of base clock changes, the RAM multiplier wouldn't change at all. If your looking to up your OC, invest in cooling, not RAM. Also, pretty sure if you go over rated intel spec (which is 1600 on ivy?), you could run into needing more volts to the CPU just to push the RAM controller. I'm honestly not an expert on ivy/sandy overclocking tho.

Would faster RAM give benefits in Virtual Machine usage?

[Curufinwe_wins]

Not really no...

In basically everything today (except for compressing and decompressing files amusingly or igpus), ram is so far past a bottleneck for the system that speed past 1600 cl 9 for ddr3 and 2400 cl 16 (higher speed due to looser timings) basically makes 0.0% difference in almost all tests.

I made a guide here!
