Question Ram voltage question

[mrduder]

Ok so I got a new gaming pc from Lenovo. I got a Lenovo legion tower 7i desktop with an intel i9 14900kf and a 4070ti super. It came with 2x16gb or 32gb of ram but was not the greatest at 4000mhz. Anyways thought I’d upgrade the RAM. Got me some Corsair dominator titanium RAM and its specs are 2x32gb so 64gb, 6600mhz and 1.4volts. Timings are 32-39-39-76 that’s all I know cuz that’s what’s on the box lol. Ok so question is, what do I set this new ram up like in my bios? Xmp does not work and this motherboard apparently doesn’t support whatever those settings are. So the only other option to get it to boot is to put everything in auto. Now, it does boot up. Problem being that it’s only utilizing the exact same speeds and everything of the stock RAM that came with it. Defeats the purpose, no? This motherboard can run up to 5600mhz. Ok, so I put that up and leave everything else on auto. Great it boots and now it’s running at 5600mhz. Well what about all the other settings with timings and voltage? Especially voltage. Does that need to be raised at all to account for the higher RAM speeds? The stock runs at 1.1 volt. This RAM says it runs at 1.4 volts. Should I up the voltage to 1.4 in my bios or leave it at the stock voltage at 1.1 volt? Thanks. Sorry I know nothing about this stuff and just want this to not only run, but run well. Cuz it does run at 1.1 volt. Just not sure if that’s ideal since it states 1.4 volts? Thanks again. And sorry for being such an idiot…… thanks in advance if anyone can be of any help here

Here is the link to the specs for the pc just in case https://www.lenovo.com/us/en/p/desktops/legion-desktops/legion-t-series-towers/legion-tower-7i-gen-8-intel/90v6000kus?orgRef=https%3A%2F%2Fslickdeals.net%2F&clickid=WP2wAyyQSxyKUY9X3AwRqR0HUkCXCiR:Uzhzxs0&irgwc=1&PID=10451&acid=ww:affiliate:bv0as6&cid=us:affiliate:cxsaam

Hello!

I am pretty sure that your RAM isn't running at 1V. It should run at least at 1.1V.

Also, XMP must be loaded from the BIOS menu.

Ok….. so yes it’s 1.1 but not sure why that makes any difference to my question??? And I know you access all of this in the BIOS. Again, not sure why you responded with that? My question has to do with the proper voltage to set this new RAM at. Do you have an actual answer to my question or just pointing out random stuff?

Hello again!

Your RAM kit has a few profiles in which you have all the specs: DRAM frequency, timings, and voltage.
You, simply, have to load the "XMP Profile 1", or "XMP Profile 2"!
No need for you to set voltages manually.

Every BIOS menu is a bit different, but try finding those settings under the "OC Tweaker" tab.

I hope this clears things up...

Yes. When I load any xmp profiles, the computer will not boot. Some of the settings within the xmp files are not compatible with my pc. For example, if I load xmp1, computer does not boot. It is most likely the transfer speed being too high for my motherboard. Ok, so just lower that and leave the rest of it as is? This is my problem, hence the question. I can do a custom profile and just run everything on auto and change the transfer speed to 5600, which is the maximum my computer can do, and then my question is, what do I set the voltage to? Keep it at the stock 1.1volts or up that to 1.2, 1.3, or 1.4volts?

Hello!

You will have to do some experiments, but as far as I know, for DDR5-5600 the voltage should be between 1.25V ~ 1.35V.
I'd start with 1.25V.
If that's not stable, try increasing the voltage by 0.01V, until it's perfectly stable.

In order to establish if your system is stable, you'll have to stress test it with MemTest86 (it takes a few hours), and also benchmark it with Cinebench 2024.
(Both are free).

I only get the option to increase or decrease the voltage by .1 so it can be 1.1, 1.2, 1.3, or 1.4 those are the only options it allows for

That's weird.
Try 1.2V first, then if it's unstable, try 1.3V.
I wouldn't go as high as 1.4V.
