Ram Voltage Help

RushNReady · Jan 5, 2014

Im in process of selecting ram memory for my build, on pc part picker its coming up with this message

"Kingston Predator Series 16GB (2 x 8GB) DDR3-2133 Memory operating voltage of 1.6V exceeds the Intel Haswell CPU recommended maximum of 1.5V+5% (1.575V). This memory module may run at a reduced clock rate to meet the 1.5V voltage recommendation, or may require running at a voltage greater than the Intel recommended maximum."

is this a problem or can i just up the voltage ? thanks

There is a lot of people that run ram with 1.65volts on their Intel builds, higher voltage stresses the memory controller so Intel put a limit on it.
To buy it is up to you it will work but if you have to claim warranty with Intel remember the limit. I personally would just get http://pcpartpicker.com/part/mushkin-memory-997125

unfortunately its not that cheap over here this is all thats available http://uk.pcpartpicker.com/part/mushkin-memory-997015

i will go for either of these

Patriot Viper 3 16GB (2 x 8GB) DDR3-1866 Memory £139.18
Corsair Vengeance Pro 16GB (2 x 8GB) DDR3-1866 Memory £142.80
A-Data XPG Gaming Series 16GB (2 x 8GB) DDR3-1600 Memory £115.99
G.Skill Ripjaws X Series 16GB (2 x 8GB) DDR3-1600 Memory £135.72

just cant make up my mind lol

RushNReady · Jan 5, 2014

or this one as its cheaper Corsair Vengeance 16GB (2 x 8GB) DDR3-2133 Memory £119.99
and has high speed

rolli59 · Jan 5, 2014

Why not this http://uk.pcpartpicker.com/part/corsair-memory-cmy16gx3m2a2133c11 other wise I would go with the Vipers above.

Quick question how comes i cant quote any one any more ? it is only when i answer in the email ? normally it used to say quote next to them answer

ill go with the pro if they better

rolli59 · Jan 5, 2014

If you have space for the tall heat sinks on the Vengeance by all means price is great. On the quote you can still do it just look it up there is a sticky about it I simply reply to.

its here now was not on the other comment crazy lol well i wanted this cpu cooler originaly untill i looked it up and saw its a monster http://uk.pcpartpicker.com/part/zalman-cpu-cooler-cnps12x
there a video on it and he only got one ram in that's not good it basically a gaming cpu as you can get away with 8 g of ram for gaming but not for video editing and rendering i want to do i will eventually upgrade to 32g so i have chosen this cpu fan as seen it installed and it got good clearance http://uk.pcpartpicker.com/part/zalman-cpu-cooler-cnps9900df what you think

im gutted about the first one being to big as thats rated really high

rolli59 · Jan 5, 2014

Should work.

here is a good pick showing http://www.hardwaresecrets.com/fullimage.php?image=49891

compared to the one i wanted

this is my mobo http://www.mobilx.hu/images/detailed/asus_z87-pro.jpg

rolli59 · Jan 5, 2014

You could mount it this way http://www.guru3d.com/articles_pages/zalman_cnps_12x_review,1.html

rolli59 :

and having the exhaust fan at the top? of the case ? well thinking about it it would not work as the gpu will be in the way and it wont get supplied with cool air even if i use the top fan to get the cool air in it will dispel the hot air over the gpu

rolli59 :

what effect will it have on my processor the memory speed over 1600 as it states that the i7is 1333/1600
ram speed compatible does this matter or will i have to change the setting s will it make it unstable ?

rolli59 · Jan 5, 2014

1600 is native but it will run faster ram on OC setting but it will stress the CPU memory controller, which can affect max CPU OC.

Tradesman1 · Jan 5, 2014

What mobo and CPU? or did I miss it, if so sorry

RushNReady · Jan 5, 2014

rolli59 :

Is it worth it or shall I just get 1600

rolli59 · Jan 5, 2014

I am quite content with 1600 in all my rigs.

It's a i7 4770k and mobo is asus Z78 pro

RushNReady · Jan 5, 2014

rolli59 :

Will change it I'm new to it all so will want it as stable as possible. I will o c it with the asus 4 step optimizer watch good YouTube video on it got clock speeds upto 4.8 with using it. Did notice the higher the ram frq the lower the clock speed would go average was 4. 6 looks good for mobo optimization will run my new cpu for 6 months factory the oc with oc insurance with Intel.

Tradesman1 · Jan 5, 2014

The Z87 Pro and your 4770K should be able to handle whatever you decide on, if going to 2400 or above may need a slight CPU OC, and Haswell likes fast sticks
