Ram Overclocking ?

[Not_Sean]

So it's been a long time since I've had nice components to play with. I've just bought the MSI Z97 Gaming 5 as well as 2x 4Gb Vengeance Pro 2400Mhz ram modules.

Two questions, is it worth it for me to up the ram speed to 3300 ? Using a i5 4690K

The other question is how ? Is it just a bios setting I change or more to it than that ?

Sorry parts are all still arriving so haven't built the machine yet

If you're gaming you'll see literally no benefit from overclocking ram. Plus overclocking ram can cause cpu overclock instabilities (p.s. 2400mhz is already overclocked).

same advice given to me

 

*edit: though its very tempting to play around with it

Overclocking ram is pretty silly, no real benefit, esp since your already at a fast speed.

 

What you can do, is declock it a step, then push your CPU BCLK higher, which takes the ram higher with it...

This is how you can squeeze some more out of your CPU OC, not really recommended..

 

Dual channel 2400Mhz at stock is pretty fookin fast.

IMO, it doesn't hurt to try. Don't expect it to 100% work though. Not many CPU's / RAM can reach that speed.

RAM chips are usually binned, so it's unlikely your 2400MHz kit will reach 3300MHz -- they would be sold at a higher price rated at 3300MHz.

 

I don't know what is the highest frequency your BIOS will allow, but anything beyond the provided frequencies will require overclocking of the BCLK.

Example, if you can only choose up to DDR3-3000MHz in the BIOS, you'll need to manually overclock your system to reach 3300MHz.

 

You'll probably need to manually play with the DRAM timings as well. 3300MHz will require A LOT more latency versus 2400MHz.

I see DDR3-3000MHz and DDR3-3100MHz kits running with 12/13/14 timings with 1.65V. (These kits cost $500 ~ $1000+, too)

you never know unless you try

 

i have a 2666mhz kit that almost does 3200mhz

 

for day to day use stay at 24000mhz 

 

no real benefit from memory overclocking

 

its just fun to do

close to 3200MHz from a 2666MHz kit?!

Sir. Impressive.

heres some ddr3 vs ddr4 comparisons

That's quite interesting.

By the way, how did you get your RAM to run at 15 Cycle Time?!

Isn't the general rule cycle time (tRAS) = tCL + tRCD + 1/2?

In your case, 13 + 15 + 1 = 29

How did you manage 15??

the only general rule is lower timings are the best!

 

i dunno. i have two sets of kingston ddr3 memory chips. both kits will run tRAS at the same value as tRCD

Faster ram helps with minimum FPS

Hmmm...don't you get data corruption if tRAS is too low?

seem to run fine

 

my daily setting is 2800mhz 11-13-13-13 @1.7V

[ProKoN]

heres my 16gb kit at 2400 11-13-13-13 stress tested for over 14 hours. it was a cpu stress test but still hard on mem chips too.

Unless you use an APU, do not overclock RAM.

[That Norwegian Guy]

Given the same generation NAND and platform, bandwith and latency evens out with over/underclocking which means just trading one type of speed for another. It's useless, unless you have a target application in mind that favors one over the other.

 

For example, a Minecraft game server would benefit greatly from lower latency, (CAS/ CL) while heavy media content creation benefits from wider bandwith. (Frequency)

 

If you use your computer for many different things, like almost everyone, then overclocking/ timing your RAM will be an excercise in trade-offs at best, and futility at worst.

Thanks guys. just ganna enjoy the 2400mhz

Ram barely gives any performance gain in games to be honest.

 

Its very minimal.

Unless of course, one just has too little ram, correct? For example, my brother has been using 1gb ram to play CS:GO. If he upgrades to 2 or 4gb, he should see improvements on game play during heavier load (Deathmatch) situations?

Yes quantity of ram is important , quality and speed no so much.
