RAM Voltage recommendation?

[Casual Cube]

Hi everyone, I am a simple man. I built my PC about 2 years ago when I had little to absolutely no knowledge.

 

i7-4790 + Hyper 212 EVO.

Asus Z97 Pro Motherboard.

 

Rn, I wanna get rid of the single slot Ram I've been using and get dual sticks. I even picked out something nice. 

Here's the problem - The CPU recommends a 1.5-1.575 Voltage restriction on the Ram and the sticks I have in mind are 1.6V I think.

Apparently that's a no no, but how bad of a no no is it? What am I looking at?

Anyone with further knowledge on this willing to share? I've read both its fine and that its bad for the CPU.

 

Pls. Keep in mind - its an older socket, To upgrade the rest of the PC for accommodating the RAM without any no no's is difficult and out of the scope for me rn. Please stay on topic!

Thanks!

Just stick to the recommended v's

For that cpu, I think it would be ok up to 1.65v so 1.6v should definitely be fine. But you should also be able to run the memory sticks at slightly lower frequency but at 1.5v, usually over 1.5 v is only needed for tighter timings and higher frequencies than normal (let's say over 1866 mhz for ddr3)

 

Unless the price is very good, it's not a good idea to buy now ddr3 memory sticks running at more than 1.5v. The last Intel processors that support DDR3 memory can only use memory sticks that work at 1.35v so if you're ever going to sell those DDR3 memory sticks the market will be limited to people with AMD systems or much older Intel processors, so you won't get a decent price for those.

More people would be willing to buy memory sticks that run at a default voltage of 1.5v or even less... so i'd suggest trying to buy those instead of going overboard with frequencies and timings on which you may not even notice a performance increase.

Wasn't the question buddy

Well I was looking into it some more and foudn the same model and color but instead of DDR3 2400 1.65V this one is DDR3-1600 @ 1.5V. 

Now I plan on using the PC for 1080p@100+Hertz, light school work including coding, and when I browse I usually tend to have upwards of 10-20 tabs open.

Do you recommend DDR3-1600mhz 2x8GB for all that?

IMHO more than 1866 Mhz won't make any difference, or the difference would be extremely small, like under 0.5%.

Even between 1600 Mhz and 1866 Mhz the difference would be small.

 

Those DDR3 2400 Mhz memory sticks will most likely work perfectly at 1866 Mhz 1.5v (I'm about 95% sure), the memory sticks will have several presets stored in them and you can just use the highest one that requires only 1.5v to work.

However, it wouldn't be a smart buy, you'd paying a lot more when you could just buy memory sticks rated for 1866 Mhz or 1600 Mhz in the first place.

 

I'd say even 1600 Mhz memory sticks would be good purchase but I wouldn't want you to always think "what if higher frequency would have made by games faster" so i'd encourage you to aim for at least 1866 mhz.
