Need help OC'ing RAM

Hello, firstly I will state my components

Mobo: MSI Z97-G45
CPU: Intel i5-4690k
RAM: G.SKILL Ripjaws X Series 8GB (2133 MHz)
- https://www.newegg.com/Product/Product.aspx?Item=N82E16820231468

So I have had minimal success in ocing my ram. I have been trying to go from 2133 MHz to 2400 MHz and be able to game and such. So far I have been able to clock my ram to 2400, but everytime I go to launch up a game it crashes (BF1 in my case specifically). I am unsure what's wrong with the OC I have atm.

OC Currently:
Voltage - 1.65
CL 11
freq - 2400

Windows is running stable as well is start up. I am on 2400 as I'm typing this, but games seem to crash.

  1. Try bumping it to cl 12. Is your cr 1 or 2? Go to 2 if it's 1

  2. i5-4690k native ram support is 1600 so any ram that runs faster than that will have zero impact on gaming. basically if you want more performance from your ram in games you want to reduce the latency not increase the speed.
    to do this drop the ram to 1866 or lower and tighten the timings to cas 9 or better.
    as a result you should be able to run the ram at lower volts while gaining about 4-5% performance for gaming.

  3. The above is horribly inaccurate. Is there a massive boost from ram speed typically no, but no gain is not correct at all.

  4. please feel free to show me a performance metric for any game that shows an increase when speed is bumped with that cpu...
    coz i have 30+ years of experience that tell me im not wrong.

    Fallout 4 also shows good gains. Depends on the game engine.

    Newer Intel memory controllers are all about bandwidth over timings so higher speed is better than lower cas at least for Skylake and Kaby Lake. They are also faster with all 4 DIMMs populated.

  6. Back to school for that guy I suppose.

  7. Back to the topic, you can't really expect RAM to overclock a whole step up and be stable though. There's not much headroom left in most RAM unless you go out of your way to get the highest quality sticks. 2133 to 2400 is a pretty big jump for DDR3. Loosen the timings or start dropping the frequency a bit. Use an overnight run of memtest to be 100% sure you're stable.

    Those Ripjaws probably don't have the highest quality ICs in them. GSkill usually reserves those for the Trident line.

    Edit 2. Should also add Haswell is NOT faster with 4 sticks. So ignore that part of my post for your system.

  8. cough all you want anort...

    that fallout bench is slanted by the fact they used effectively lower latencies as the ram got faster.
    if they had of use 1600 cas 8 against 2400 cas 12 there would be no difference in the fps...
    but they didnt... as the ram gets faster they effectively reduce the absolute latency when they drop the cas to 11.
    and thats where the fps increase came from

  9. And the overclocker review? It is cl8 1600 vs 2400cl11
    Reply to Supahos
  10. yes 2400 is 1/3 faster than 1600
    if the test was legit they would have used cas 12 which is a 1/3 slower than cas 8 which would give effectively the same timings.

    the increase in performance didnt come from running the ram faster it it came because they used effectively lower latency timings. which reduced the absolute memory timings.

    like i said mate its a skewed test.

    https://en.wikipedia.org/wiki/CAS_latency
    go here look at the listings for cas to ramspeed to ns timings.
    because it looks like its you than needs to go back to school and take a lesson or 2. supa :)

    also read through the reddit and you will see what i said is confirmed.

    i thought cl 11 was faster than 12? Im at 11 right now. Or am I missing the point?

  12. 11 is faster. 12 is more likely to work. Same with command rate if it's at 1 change it to 2.

    Well, it did actually last longer, but still ended up crashing (the game itself). I had noticed in my bios settings I have to option between either cl 12 performance or compatibility, I chose perf. Does this mean anything?

    Not sure on that option. Try compatibility and see what happens. I suspect nothing different but worth a shot I suppose
