Overclocking Corsair Ram.

[JinnXV]

Hello, I'm trying to overclock my DDR4 Ram from 3000MHz to 3600MHz. I am not sure where to start, the specs are;

 

2x8GB

15-17-17-35

1.35V

 

I think i can run it at 3200Mhz without chaning anything. I stress tested it using OCCT memory test for ~15 minutes and it seemed fine, not sure if should have went longer.

 

Any ideas were i can start to adjust timings and what not? Thank you.

First thing you should do is figure out what memory ICs you have on those memory chips so you know what the safe voltage range is. You can do that either in Thaiphoon Burner, or with Corsair sticks you can look at the label to see a version number, and while there's a way to decode it by hand, it's generally easier to just Google "corsair version X.XX" and see what pops up. 

 

Once you do that and set that Dram voltage, loosen out the primaries to something like 20-24-24-50 and try to go for the max boot able frequency that will pass a memory intensive benchmark (this is to make sure that performance is also increasing at the same time). Depending on your platform you might want to set some other things first (on Intel you need to set some memory controller voltages depending on the specific generation, on AMD you need to set the SOC voltage to 1.15V and make sure to manually set the FCLK to half the memory effective speed), but keep increasing the frequency until you start failing to run those benchmarks. Once you do that, start doing what you did before but lowering the timings, making sure you're somewhat stable, then doing the next. Once you get through all your primary timings, I'd start trying to make sure it's memory stress test stable, increasing the primaries slightly if you start crashing or otherwise having issues. 

 

After that, move onto the secondary and tertiary timings, though the specific ones to adjust differ depending on the platform you're on (Intel has a lot of timings that don't actually exist, while AMD is generally a bit better with that), and finally do a long, overnight stress test to make sure it's fully stable.

Determine ram ics, im not too familiar with corsair models but you can also determine with thaiphoon burner, send a screenie of thaiphoon burner to identify ic

This does depend on how sensitive your ram is to having everything set right, at higher freq thisll get worse but at slow <4000 you should be avoided from the torture that is high freq ram oc, so realistically this should be ok, though id problably just set jedec cas22 primaries cause jedec is guaranteed to work on basically everything

 

For tightening yes do primaries first though i advise against dumping volt into primaries, trfc will do more for performance than just cas, definitely tighten primaries since there is a performance benifit though i dont suggest dumping more than 0.1v into em, rest of the voltage dump into the subtimings, trfc should scale abit from volt but at some point itll also start gobbling tons of volt like cas so avoid making your timings gobble up volt, not sure about the other subtimings but major ones aside from trfc are trc, trrd-l/s, tfaw, and literally all the tertiaries. Subtimings aside from trfc should really gobble much volt, maybe twcl will gobble some volt if you tighten it abit
