[SOLVED] Set RAM to advertised speed without XMP?

ak8268 · Nov 16, 2018

Hi,

I have a question regarding OCing my RAM to the advertised speed I bought. I built a new PC recently and the RAM speed is default 2133MHz as expected. The RAM I bought is advertised for 3200MHz. I read that XMP might make changes to the CPU and as a result may increase temps. If I set the RAM manually to the spec on the package, will it modify or will I need to modify anything on the CPU side? Or do I just change the values for the RAM in the BIOS and call it a day?

Thanks

My build:
I9 9900k
Asus Maximus XI Hero
2x16GB G Skill Ripjaw V

RAM Spec:
PC4-25600
Voltage
1.35 Volts
CAS Latency
16
Latency
16-18-18-38

Just change it in the BIOS to exactly what you have here...timings and voltage. If it doesn't boot up on first try, let it try to restart a couple times (that's the motherboard trying different secondary/tertiary timings to see what works).

Why bother?
Ram has the settings best required to run the ram at the advertised 3200 speed imbedded in one of the xmp profiles in the ram.

Ram faster than 2400 speed or so will be overclocked using a higher than standard voltage.
That may well impact temperatures or overclocking regardless of how it is set.

Implementing an xmp profile is just a short hand way to get those settings that the ram vendor has determined to be optimal.
