or to downgrade official bios no capable with ezflash. (320x to 120x not is posible... i read it, not test)

In all the time we spend monitoring our voltages we just don't see these spikes. Some would say the equipment being used to measure is not fast enough to see the spikes, but I feel the amount of time we're monitoring our systems is plenty enough for us to be able to see these spikes in HWIfo (Or Aida etc) - I see other voltage spikes elsewhere so why not here?

Anyway, I have put my trust in the evidence that's been provided on this thread on many occasions. I find it hard to believe LLC will damage anything - settings that have dangerous settings are highlighted for us in the bios using different colours to represent risky settings - yellow for some risk and purple for high risk.

I think that Anty, soureraser and Acidstorm replied for me. So I have nothing to add about that.
Anyway, do what you think is better for you wink.gif

1. Spikes are on order of 0.06V as measured and shown by AMD engineers on one of their posts/videos (can't find the link now) - so since we know that AMD suggests keeping voltage below 1.425V for the long term OC-ing, then to be perfectly safe we should keep below 1.34V LLC5 to get the same.
2. Personally, I will be exchanging this CPU for ZEN2 or maybe even ZEN+ so I don't really care if I damage it a bit in the meantime. That said the real damage is done when running transistors with high voltage and temperature constantly for a long time, as in setting 1.425V and playing with 48H of OCCT to test stability, jumping power states and resulting spikes in voltages in the same frame of 1.425V for miliseconds will do the same damage after 20 years wink.gif

On another topic, my CPU is unable to stabilize at 4.2Ghz with memory set to 2933 - I can run it at 4.2 but with memory at 2400 - so no deal for me.
The final score is 4.1Ghz at 1.368V with SoC at 1.025V and good timings for memory. I like this smile.gif


So your final score with 4.1 ghz is 1.368v LLC3 or 5?
And ram speed, timings and voltage?
What stress test have you passed (like 2 hours OCCT, 6 hours blend/custom max ram, 1000% memtest?) can u post some screenshot?

I want to compare if there's really a gain with a newer cpu like yours 38week vs mine 32week smile.gif

Yes.....I've been OCingt since the 486DX2 (or earlier!). More recently I have been with AMD and have never lost any components - 1 MB failed, but not because of OC. Pretty sure my FX6350 was runnning with LLC 5 - for years.

CSM Mode: I have been able to boot non EFI OS without doing anything in the CSM section, but not tried Win 7.

My failure to find any clue of voltage spike from LLC 5 with my very cheap oscilloscope may not be considered as an evidence.

The safest way to use LLC 5 is to plan a +0.07V spike while setting the core voltage, which implies to set it below 1.35V to avoid any potential spike to push it over 1,42V.

The core voltage could even be set a bit higher as 1,425V is the maximum permanent voltage, which means the voltage could go temporarily a bit higher with any risk of damage.

LLC5. I have a Micron based 3000 ram in 2 1-rank modules. Clocks are set on auto DOCP 2933 with all settings on auto.

Yes to OCCT but only 1 hour (meaning that I did not test more, not that it crashed), 6H Prime95 small fft and Handbreak 4k60 h264 to 4k60 h265 conversion (about 3 hours).
Memtest86 in UEFI mode on all cores - about 4 hours. For me it is enough though may not be up to the highest standards here (24-48H testing that some people do).
Temps never crossed 70C, and if I was really pressed for stability I would just go full speed on watercooling and could keep temps about 60C.
If I ever feel the need for retesting for stability I will take some screenshots smile.gif

So I can confirm I'm Rock Solid at 4050mhz 1.356v LLC3! With the new 3203 Bios!

Some screenshot here (OCCT + 1000% Memtest + Prime95):

Benchmark: Cinebench (1820pt) + Aida64

Bios Settings:

171121102900.png 171121102910.png 171121102951.png 171121103007.png 171121103021.png 171121103036.png 171121103057.png 171121103117.png

So my problem was the C-States enabled (I don't know why... probably because I'm really at the lowest voltage possibile to be stable?)....
Tomorrow I will try to retest again OCCT but with C-States enabled again.

How much power I will not save with C-States disabled? I have see no big difference in Hwinfo....

Interesting results! I am new to overclocking with LLC, all the motherboards I had did not have that option, and I have been reading about it for quite a bit, isn't 1.356V + LLC3 considered a bit high? My 1700 runs stable at 3.85GHz with 1.32V + LLC3 or 1.35V + LLC1 max temp 70C with D15S

Solwed my problem with dual boot, those settings have to be applied:

Nope it's in really safe voltage... I can safe push to LLC5 and stay in the virtual safe voltage from amd (1.425v (safe) = 1.356v + 0.07v voltage peak from LLC5).

Also my cpu is considered really lucky... if you are stable at 3.85ghz with 1.32v LLC3 you can try to overclock to 4 ghz ...
But going to 4ghz or moreover to 4.05ghz is really different from overclocking to for example 3.90ghz, you can find a graphics from lermite in the last post in this thread.
It can require hard voltage for only a little difference.

For example I can pass OCCT at 4.1ghz only with 1.4v LLC3 (so I require 0.05v+ for only 50 mhz).

I have my vcore set at 1.175V on my 1700x at 3.8 ghz and I can run 3.9 at 1.212V. LLC is at 5 as recommended by this thread. Are these voltages safe? I stress tested with real bench and vray and it's working fine....so I don't even know.

I'm also looking at SVI2 in hwinfo and its at the voltage I set in the bios so i'm guessing that's the right one to look at?


Help welcome.

Yes, we will wish @F0RCE963 good luck in running his 1700 in 4.05 and 4.1 stable like you are, not to forget your RAM results being really impressive. Also, this is with the Prime board, not with the Crosshair board (which is a totally different story).
