    what voltage dose hcf0 scale with on amd

    i just got my gskill kt back from RMA and they sent me a 1.9V 1600mhz 7-7-7-18 kit with HCF0 chips in it. since those chips range from 1600mhz 7-7-7-18 1.9V and 2000mhz 8-8-8-28 1.9V 1600mhz 8-8-8-24 at 1.65V for i7 parts whats the voltage the like to be at and what range can i expect with a thilban. and do they like high ras and tras values like other 1.65V kits do.

    Thubans dont like that much voltage over time. I dont remember exactly, but Chew* said somewhere around 1.7-8v i think. Ill see if i can find the excact quote.

    Edit: 1.75v

    lol

    I was gonna answer in this thread but was afraid of getting shot down.

    He wants to know what voltage HCF0 starts to ramp up clocks and timings at, as in what's needed to run a decent clock/volt.

    IMO 1.8v isn't going to kill the IMC, 2v over time definately might but the most I think 1.9v would do is slowly degrade over long periods of time.

    I'll go and say right now I recently pushed 2v with a 1100T for bout half an hour with a couple of D9GTS, no harm that I can see done, sticks + IMC still do 2020 9-9-9-24 @ 1.8v

    i want to know what it would clock like on the thulban and what votage range it stops scaling. i have a denab based chip and a thulban and im deciding if i should go with the hcfo or elpeda bdbg

    Honestly I'm not sure how HCF0 acts though I'm pretty sure iirc it's similar to D9GTS but slightly less volt tolerant, more like JNL.

    HCF0 would probably rock on an older (anything before ~1020 week) Deneb chip, BDBG will act more like Powerchip, you will have to run higher trcd.

    HCF0 is not gonna want to be put over about 1.8-1.9v considering I saw eva2000 at i4memory using 2v for validations and 32M runs.

    Honestly it's probably going to clock like your degraded D9, you might get 1600-1700 7-7-7 at 1.8v as an estimation.

    Hopefully people realize I'm just speculating here, I'm not stating facts.

    i was hoping to get some1 like eva or chew on this. i guess for the 1st time in a long time i get to play with something that i have no idea what it will do

    edit- one stick came dead so i dont even get to play with it, i thought that gskill tested kits before shipping them out for rma but i guess not.
