Are low RAM timings cutting reads and writes?

Question

RAM

Hello everyone, there are two dies 4gb (1333mhz) + 8gb (1600mhz) of different companies, they work in dual mode at a frequency of 1333 and timings 9 9 9 24, but for some reason after setting 8 8 8 24 the write and read speed is cut according to the results of the Aida64 test , I thought the lower the timings the better or I don’t understand something, thanks.

Answer 1

timings - response time, the less - the better, here you are right.
Your mistake is that you only look at timings, and besides them there is also a frequency.
When overclocking the timings, the frequency decreases (as far as I remember, I last touched the BIOS about 5 years ago). And the speed of work is affected by both frequency and timings. At the same time, a high frequency in the default case is better for the default user. Each case is specific, but I assume that in your case, by lowering the timings, you lowered both the frequency and the speed of work became less than it was before.
And the iron rule - if you don’t understand what you are doing - return everything as it was, and don’t touch it anymore, it’s better to read about the memory device. When you read it and you understand what's what, then do what you want.
I'm serious, now you'll climb to overclock the processor, and there you will most likely need to add voltage, and you will most likely need to drive it along the bus, and the bus drives everything else, incl. RAM. You burn something, in short, but now the equipment is not that cheap.
