ok, i just check that mostly our ram speed is 2133/2400MHz @ 1.2V, timings 15-15-15-36 at default, so when we enable xmp in bios, with XMP is 3200MHz @ 1.35V, timings 16-18-18-36 , so it's 40% to 50% overclock. correct me if i were wrong.

Ah I see.. interesting.

XMP is all overclock. It is generally what we called sanctioned OC as the manufacturer has tested and somewhat validated that the kit can run at that speed and voltage in general setup. Thus a better cpu/motherboard configuration can potentially extract even more.

ahh, ok. so that's mean i've already oc the "stabil" stage setting at bios which is the xmp 1.0. My m/b bios cannot set xmp 2.0 as there is no option for it. i guess it need certain requirement like good m/b and CPU i think.

Done some minor RAM timing adjustment, I hope this is the final one.

i thought The Verge cable management was bad, then I saw this...

want to ask, on same spec, almost same configuration, 32gb of ram win over 16 gb ram. major on multiscore geekbench.

valid justifaction for additional RAM?

more like, what is your usage? of course benhchmark will show massive gain, but if your daily utilization is even barely 16gb, 32gb is not gonna benefit you that much isn't it ?

32gb ram sticks also have a more likely chance for dual rank. So that will also add some performance.

Xmp 1 and xmp 2 profiles are stored on RAM by manufacture.

Look into bios settings.

Or what mobo you using? Someone could help here.

i've already checked bios only have 1 profile which is xmp 1.0 and my motherboard is Gigabyte B560M AORUS PRO AX
processor is i5-11400F, GPU is AMD Radeon RX570.

It depends on the ram. But both generally just loads a set profile of speed, primary timing and voltage. So technically no difference. You are better off with manual adjustments, when you have more confidence after reading more guides ... or get someone to do for you lolol.

ok bro, thx for clarification

You can follow what piscesguy did at going gear 1:1 to get some extra latency performance. Maybe even set your command rate to 1 as most motherboard xmp will run at 2. And most importantly drop your vccsa/imcvccio voltages

ok sure, will look into it too, thx

what are the 2 XMP profiles that you are expecting? to get XMP 2.0 working, i think you need luck with gigabyte's bios.

Well I modified my RAM from 2666mhz 20-22-22-52-540-CR2 to 3200mhz 14-18-18-32-480-CR1, what a journey.

maybe your are right, maybe bios need to update or what not. i actually user from 4th generation intel so i just exposed this xmp and gear ratio feature. so i still slowly taking my time to understand all this. If can enable or push a little , i think will try it out, otherwise i just leave it at it is as default or auto.

thx

What I think he meant is, xmp 2.0 carries some secondary timing profile into the bios when enabled instead of having the mobo bios auto configure it with xmp 1.0, so it might cause instability.

However you need not worry, you motherboard doesn’t detect it is most likely your ram stick doesn’t have xmp2.0 saved inside it anyways. Afterall in the end, what xmp does is load a preset value to the bios which you can manually set them yourself anyways.

Back in the days before The invention of XMP, all the values you see on the ram packaging have to be set manually.
