[SOLVED] overclocking my ram

[Afro_ninja199]

hiya all

this is the ram kit i have
https://www.mightyape.co.nz/product/26620045

i changed the speed from 3000 to 3400 and it seems to go fine, no crashes ( have had it like this for a month or so ), ram is now 3400 CL17 ( was CL15 )

is it as easy as changing the speed or would i be better off leaving it at 3000 CL15?

userbenchmark link is here https://www.userbenchmark.com/UserRun/42164843

is there any other tests i should do?


cheers

if you game, you could test is to run a game
or do memory test

To summarize this: faster memory clocks decreases true latency on the RAM, which gives better performance overall.

Also if you were to calculate the latency with both 3000cl15 vs 3400cl17, they'd be exactly the same (10ns vs 9.99ns). So I wouldn't worry too much about what you're configured at right now. If it's stable and runs smoothly, then all is good.

Run memtest86 or memtest86+
They boot from a usb stick and do not use windows.
You can download them here:

MemTest86 - Official Site of the x86 Memory Testing Tool

MemTest86 is the original self booting memory testing software for x86 and ARM computers. Supporting both BIOS and UEFI, with options to boot from USB.

Memtest86+ | The Open-Source Memory Testing Tool

Memtest86+ is an advanced, free, open-source, stand-alone memory tester for 32- and 64-bit computers (UEFI & BIOS supported)

If you can run a full pass with NO errors, your ram should be ok.

Running several more passes will sometimes uncover an issue, but it takes more time.
Probably not worth it unless you really suspect a ram issue.

Intel does not depend much on ram speed for performance.
Here is an older study:

Skylake Memory Scaling with Kingston Predator DDR4-3000

Armed with a massive 32GB high-end Kingston HyperX Predator DDR4-3000 memory kit, we investigate how DDR4 frequencies and latencies affect real world performance on Intel’s latest mainstream desktop platform. October 13, 2015 by Lawrence Lee Product Kingston HyperX Predator DDR4-3000 32GB...

You are looking at miniscule actual performance differences.
