X99 overclocking

harry9877 · July 19, 2020

Just wanted to share what I've been able to do so far

motherboard: Asus X99 ws/ipmi

Cpu: xeon e5 1650 v3 @1.25volts @4.6Ghz

cache so far is at 4.2 ghz not tuned yet but just wondering if that is a good voltage for 4.6 ghz waiting for a better cooler as it is a power hog over 210watts in hwinfo64 when I was trying to see what I could get max with my setup the now

Also I did by some ecc ram apacer 2x8gb kit of 2400 cl17 I got that upto 2810 when I had 105.2 bclk but did have to drop the core to 4.4ghz and timings are in the pics

Also the timings I left auto is there a performance benefit dropping them and also what is dram rtl and iol as I can tune them for each stick but never seen those timings before so not sure what benefit there would be

Hello @harry9877, I also have the same motherboard (Asus x99 WS/IPMI) and CPU (E5-1650v3) but I can not overclock the CPU in BIOS through AI Tweaker using "CPU Core Ratio", the CPU Core ratio is set to auto and the option is grayed out, I can't change it even though the CPU has unlocked multiplier. I am curious about how did you manage to overclock your CPU, please share your method. Can you change the CPU Core multipliers in your bios? or Did you mod your bios? or did you use some other method?
