What values should I set for Row Cycle Time (tRC), RAS to RAS Delay (tRRD), and Read CAS to Precharge Time (tRTP) RAM timings?

I would like to know how to set these values for stability, and also how to set them for performance.

I should clarify I have no idea what these timings do, so I would like to know a good number to start off with for each timing before I start testing. I would also like to know whether raising or lowering the value of each timing will cause more or less stability. For example, if I input a value of 11 for tRC, but that caused instability, I would like to know if I should raise or lower that number to try to improve stability. Same goes for the other two values. Thanks.

You set those parameters in the BIOS. I suggest reading your motherboard users manual.

Carefully

I would start by selecting the highest clocked XMP profile , with a reasonable voltage .
From there make small changes manually to either tighten timings or increase speed , or both .

Expect the computer to let you know you have gone to far by locking up and you having to reset the BIOS .

There are no XMP profiles in my bios. I have to set these timings manually.

what is your motherboard?

lower timings
lower voltage
higher frequency

all move you towards instability

My motherboard is an ECS.

No more clues? Like the actual model?
