custom settings for my ram, please help

[Space Lynx]

So my new coffee lake build, my ram does 3200 at cas 16-18-18 (not XMP) MSI mobo BIOS speciality called "Memory Try It"

well its rock solid stable... so I was wondering if I should try custom settings in BIOS for ram, and bring that down to 3200 CAS 14-14-14 like I see on more expensive memory? Maybe I won the silicon lottery?

What settings do I use to get that CAS? I'm running i5-8400 coffee lake build.

Reference the ram makers site, look at kits within the same series, look at timings and voltage, thats how I did it on my platform. Now intel has additional voltage tweaks so you would have to ask @cdawall or @cadaveca

If anyone reads this and has a coffee lake build with CAS 14 DDR4 3200 ram, please screenshot it in advanced ram settings in BIOS so I can see all of those fancy numbers and copy/paste.

If your memory is 3200 MHz cas 14, there should be an XMP setting in your bios for it.

I think he has ddr4 2400 according to his system specs.

I dont see the point in tweaking more, honestly. Performance difference is nill....that vs time to check if its stable??? Not worth it to me.

Push the botton ,because there is a button.

 

[cdawall]

Is it a Z370 board, or is it a lower tier board? XMP doesn't work with the low end ones.

? What button you speak of? lol im so confused

I am using i5-8400 coffee lake (sorry sig is my mobile rig) so yes my mobo is MSI Z370 A-Pro and I amusing BIOS "Memory Try It" to take my cheap $100 ram from 2400 speed to 3200 and its rock solid stable, so I was curious if i could bring down my timing to 14 instead of 16 like the really expensive 3200 ram.

I think the cas 14-14-14 over 16-18-18 actually gains 3-5% fps in gaming over ddr4 2400 speeds. according to linustechtips a video he mad eon ram. diminishing returns after 3200... but i think you need CAS 14 to get the real benefit of those fps gains at that speed.

 

[eidairaman1]

As i said reference the sites kits in my last post, if they fail bump it up 1, I however would only adjust the cas first and then the next value etc etc

All you have to do is change the first four timings; the MemoryTryIt! profile will take care of the rest. You can try 14-14-14-34... but there are two distinct line of Samsung memory chips out there in the wild; one will be able to do this, and one will not. The that does not will likely only run 16-18-18.

It is also possible you have some of the top-end Hynix chips on your memory, and these chips are not capable of running that CAS 14 @ 3200 MHz at all. You may want to boost vDIMM to 1.4V while testing this out, set vccio to 1.185V and VCCSA to 1.125V

That board has an xmp button in the bios. Read the owners manual and try selecting it.

This thread has a line at the top. Try reading it and see how your comment is out of context. Heh. /

XMP is 2400 MHz, user is running 3200 with those 2400 MHz sticks via the board's MemoryTryIt! profiling in BIOS.

Click the xmp button and push the clock speed up. Same thing silly.

But he asked for help getting C14 as he already has the speed up to 3200 thanks to the BIOS profile... he/she just has no idea on what timings to use; see below:

What settings do I use to get that CAS?

I would bet the XMP for 2400 is like CL14...

Could be, but you can't have XMP and the memorytryit profile loaded at the same time... they will overwrite each other. Memorytryit loads more than just the primary 4, fortunately... it's actually a nice feature rather than a rather mundane one.

You can dump memorytryit for the XMP to force the clockspeed with the xmp timings

adjust just the cas first, then the next timing etc, adjust vdimm or w/e cadaveca said on voltages, if it doesn't lock up run a test like Blender with Ryzen if it does then follow daves directions.

XMP autosets timings, you can leave it on and then adjust from there, that's what I did on my rig it is called DOCP though

Memorytryit adjusts the secondary and tertiary timings to what suits the chosen speed, which isn't going to happen when you just enable XMP. That why it is recommended sometimes that when memory kits don't work (like with the Ryzen launch), you try using just primary timings and letting the board do the rest... it's the secondary and tertiary timings from the XMP profile that might be causing the issue. MemoryTryIt offers an easy way to adjust those timings for those that don't know how to do it manually. It also sets the primaries, but those are far easier for most to change compared to the oodles of timings for other "domains".

Perhaps understanding that is why my advice is much different than yours.

Dave thats true considering my board has more than what I adjusted below in my signature, I only used DOCP and adjusted from there, my kit is running at 1.65V default it runs at 1.6.

I just manually set everything based off of. Personal knowledge, but that isn't what he was asking otherwise we would be sitting here for hours saying which setting will work best. He hasn't even tried just clicking xmp and setting 3200 for the strap so no one knows if it will just work.

XMP 3200 still runs at 16-18-18 like Memory Try It.

I went to the website: https://www.gskill.com/en/product/f4-3200c14d-16gtzr to see if I could find all the technical specs to try CAS 14 manually but its not on their product page for it. eh. oh well I guess I just will be happy with 3200 16-18-18.

At that point you have to go and manually set it all.

This is what I was asking in my first post... XMP and Memory Try It in BIOS only do CAS 16-18-18... I was asking for someone to post a picture of their BIOS with CAS 14-14-14 DDR 3200 ram so I could see what all the specific settings are...
