Hello everyone,

I have a question for you :)

As I am in love with OCing, been doing it my whole life with GPU and CPU I started to get interested in MEM overclocking too. Or well ... overclocking ... My DDR4 LPX Corsair 2x8gb run at 3200Mhz it is rated for at 16-18-18-36 2T CL with XMP profile at 1.35V.

I am more interested in tightening the timings. 16-18-18-36 2T seems sad to me. I'd like to know some good programs for MEM benchmarks to know the gain as I was able to get, for now, stable 16-16-16-28 2T at 3000 Mhz or 16-18-18-36 1T at 2666 Mhz. To be honest .. I was like "let's try what happens" and from all the possibilities I've tried these two were OK. If I try to lower the CL while also adjusting from 2T to 1T the PC won't boot. Or if I try to use it with higher frequency.

I'd like to hear opinions from some more experienced OCer what is better, if it's frequency or timings, if I should sacrifice frequency and timings to get 1T stable and so on. Also how to proceed with OCing the RAM the best way. If there is some kind of pattern to use. To be honest, I cannot find anything browsing the google so I really am just trying what comes to my mind when trying to figure out the combinations.

Thanks in advance!

Overclocking is more of a trial an error basis kind of work. In the past you needed to fiddle with a lot of things and keep a paper and pencil handy to keep things noted. You should keep to your existing settings if they aren't causing any issues. You may also want to read through this thread and this article.

The issue with the rams not going over a particular frequency at 1T is due to necessity for higher voltage or relaxed timings. The trade off to having generically binned ram chips.

With all that being said, what are your full system's specs since overclocking is more of a package than just asking the BIOS to go to a certain magical number. As per your inquiry to memory benchmarking, try this, this or this.
