OC Specific RAM. Can I?
OC Specific RAM. Can I?
Hello everyone,
I own a 2014 PC with a 4770k OCed at 4.5ghz @ 1.19v on Maximus VII Hero MB.
My current RAM is listed here: https://www.gskill.com/en/product/f3-2133c9d-16gxh.
It functions at 2133mhz @ 1.6v, but I’m not sure about the CAS and will check later.
My old EVGA GTX 780ti Dual Classified stopped working recently and began displaying artificial pixels, so I upgraded to the Gygabite GTX 1080 G1 Gaming.
If this affects anything, my PSU is an EVGA 1000P2 (platinum certified).
My case offers good airflow – Thermaltake v71 with removed docks, two additional fans (one button and one top), plus extra dust filters. I also keep CPU temperatures below 70°C during extended stress tests in the summer.
The cooler I use is a Noctua NH-D14.
I’m sharing this information because it could be relevant for the RAM’s OC.
In my BIOS, which I recently upgraded to the latest version, I can set the RAM to 2400 and even 2600 MHz. When I try 2400 and restart, the PC briefly powers on and off (after a short delay) until I perform a hard restart or power it off completely.
My question is: can this RAM be successfully run at 2400 MHz?
Thanks!
P.S. I’m planning to increase my RAM’s speed as I noticed performance differences between 2133 and 2400/2600 MHz in certain cases.
Ram chips are binned, and the better ones are sold as higher speed ram.
2133 will normally be as high as you can go.
Sometimes one gets lucky and can go higher.
The restarting is an indication that the motherboard is having difficulty with the ram setting.
Not to worry, your real app performance or fps will not be significantly different with faster ram.

If you were to modify the RAM, you could potentially reach up to 2400Mhz, but you'd need to increase the timings (the cl 9-11-11-31-2N 1.6v RAM). You'd likely also have to raise the voltage and adjust the timings significantly to achieve faster speeds. I wouldn't suggest doing it at all. If you're interested in trying, you'd need to make all the changes, which would slow things down overall. Then you could try setting it to 2400Mhz and possibly increasing the voltage, though that could cause damage. That's why I advise against it with this system.
What you see in CPU-Z corresponds to the image at the provided link.
these are maximum speed ram capabilities; you won't be able to exceed them.

First of all, increasing the RAM speed will lower your memory bandwidth. Overclocking RAM doesn’t offer any advantages—it can cause stuttering because the HDD slows down. While the processor runs very fast, other factors like virtual memory and shared GPU memory still matter. If you overclock RAM, you might disrupt these connections.
