RAM OC issue

[gbergeron]

See signature for build.

 

So here's the deal. I updated BIOS to latest version, and since then, seems like everything has way too much voltage.

 

I have a 3000 mhz ram kit, when I set the XMP on in the bios, it sets my RAM voltage to 1.45 ( why so high ??? The ram says it should run at 1.35 )

 

Also it set the vccio wayy too high ( 1.335 ) and System agent too very high. If I would have set them manually like that, it would show as purple ( u know to warn you its very high voltage )

 

 

So is it possible the newest bios has fucked up ? Why voltage become so high, before the bios update, everything was fine. When setting XMP, it would set the ram voltage at 1.35 etc..etc..

 

 

The issue now, it seems weird, but since the voltage is higher, I get weird sound issues. Like ...

 

Best way to describe it, is you know when you have a voice convo online and the guy always mute/unmute his mic, the little *clic* sound it makes, this is what it does now. I would per example watch a youtube video of 3 min, and I can hear clics here and there during the entire video.

 

I then go back to bios to set all default, and the sound issue is 99.99% gone.

 

I tried all newest drivers, oldest etc.. it really seems to be linked with the ram voltage.

 

Any idea ?

Note that when using HDMI audio on my TV, no sound issue at all...

Can you go back to the old bios version? Unless this new bios has specifically fixed an issue you were having, it sounds like it's a lot more trouble than it's worth.

 

I have a Z170XP-SLI gigabyte board, and I have not updated the bios on it (to enable KBL compatibility) since I know I couldn't revert back, so it's possible you're stuck with the new version now.

 

Does CPU-Z show 1.35v for the xmp profile on the ram? Are you able to enable XMP and then manually tweak the voltage back down?

Can't revert because ASUS......

 

CPUZ doesn't show the ram voltage... but OCCT shows 1.46 vcore...

That's way too high if it's legit. I'd recommend trying to manually run the kits at that speed instead of relying on XMP, sicne it's pushing your cpu way too hard on auto if it's actually putting that vcore through the chip.

 

I attached an image in spoiler tag as to what I meant on cpuz - the SPD tab should show voltages for your ram kits XMP profiles.

it shows 1.35 in cpuz at the last one : XMP

 

Concerning the 1.46 vcore, i meant on the RAM voltage.

 

My cpu is at 4.5 ghz @ 1.34 vcore

Yet what I did is just set the ram voltage manually to 1.35 ( it shows 1.36 after ) and set the VCCIO and SA voltage lower, around 1.0

 

It did resolve almost entirely the issue, but sometimes i still hear the clic sound

That's also super high (unacceptably high) if you're running a normal profile. Try manually clocking the ram to that speed at 1.35 manual and see if it improves.

This is what XMP sets :

As you can see it shows 1.35 but left to it it says its at 1.45 so im unsure why it shows that ?

 

Also see how the VCCIO SA and Stand by voltage are at ? Way too high ?

 

Usually these are around 1.0 v

If running it manually helps, I'd say try to keep tweaking down to as close to the settings you had set before the bios update. It might be an actual bug introduced with the new bios that causes the audio issues, in which case this is possibly only going to help your component lifetime/reliability and might not fix the audio issue completely. 

 

Might be worth checking the asus forums as well to see if anyone else has experienced it and if they were able to fix it.

If there's some kind of offset being applied, you could try to reduce your manual voltage selection (to, say, 1.3) to try to bring the ram down closer to 1.35 real voltage - assuming that's what the number to the left indicates.

I've researched too much already loll 

 

The only info I found is a guy who had the exact same issue as me, and he said he resolved it by OC the ram manuually, timing and voltage, and that the issue he said was probably VCCIO voltage too high.

 

So this is what i've done too, and it seems to have resolved the issue like 95% but sometimes I still hear those clics behind when watchin a video etc..

 

Any idea what should be the VCCIO and SA voltage for 3000 mhz ram ?

 

Also just so you know, I've set manually everything and the ram voltage shows 1.36 when setting it manually in the bios

Default SA voltage for my 6700k at stock with 2666 ram is .94v, and my quick searching indicates that <1.1 is fine for 24/7 use. VCCIO is similar, for me it's at 1.06v.

 

I have absolutely zero clue whether these voltages would need to be raised dramatically for 3000mhz ram, I don't have any kits that speed to test it with - and it might vary by board (or board manufacturer, or memory kit (xmp)...) so I'm not sure if I can give a definitive answer there.

 

Perhaps if someone else on here has the same board as you they can give some insight.

Before I update the bios, XMP was setting 1.35 for the ram, something like 1.0 and 1.1 for IO and SA

 

So I am unsure why they have put so much higher voltage for the newest bios... maybe there was issue with the kaby lake support on this board... not sure...

 

I set it at 1.06 for VCCIO and 1.1 for VCCSA  and it passes stress test etc...

 

I don't really care about the auto settings since i can oc it manually and i know what the voltage should be but i am just concerned about the sound issue, the clicking...

 

Its kinda gone now, i'll see if it happens again..

 

thx for ur time man

I know it might sound weird, I tagged you so you know, I have switched the RAM slots ( 2X 8gb ) and the issue is gone. No more sound crackling at all at the said correct voltage etc...

Very weird to me so maybe I tho u wanted to know this was possible lolll
