Help overclocking F4-4000C19D-32GTZR on asus maximux XI extreme with i9 9900k
I have the latest bios and if I just enable xmp profile , the auto setting for the ram , does not allow my pc to boot.
we need to manual set up the ram options in Asus bios .
Did u guys ever tested your rams with the asus motherboards ? You have advertised that you did and that is why I bought your ram.
How is that possible that you guys do not have pre settings to share with us for having your ram work on the asus maximus xi extreme , with your ram overclocked ?
As CPU , I have an intel i9 9900k , which should be the most powerful CPU to date .
How were you guys able to have your RAM work ,when mine does not work, and mine is less powerful than the one you tested ?
Why are you guys advertising your RAMs as fully compatible when they are not ?
What is the setting that works for your RAM ? I find it absurd that there is no support for it with pre-settings that work for the motherboard and cpu I have
Top model CPU doesn't mean it will OC the same as all other same model CPUs, some will still OC and perform better than others. We must test hundreds of CPUs to find a couple to support DDR4-4600+
Again, the RAM is fully compatible and capable of XMP specs if using a combination mentioned on the G.Skil QV, and granted your CPU is capable. The pre-settings is the XMP Profile, but if you don't have a motherboard and CPU combo that can support it without any BIOS changes, it will not simply boot up and run at the rated specs. In those cases you need to test and see what it can do by manually lowering DRAM Frequency, then you can try to move up and stabilize by manually inputting certain settings. When custom building an extreme system, this is what it takes, and why you won't find a pre-built computer like Dell or HP that has DDR4-4000+
This is the system I have and if there is no support from gskill about this ram I bought and that based on your article and advertising seemed doing great on the asus and on the i9, the only option I have is to return it
I would like to help you but I can only be as helpful as the information you provide. I'm not physically there to get the information I need to troubleshoot so I am counting on you.
Which slots do you have the RAM installed in?
What settings did you attempt?
Without any specific details about what you're doing or trying, my help is limited.

ok. Thanks.
i am using slot 1 and 2. There is no color specified pattern on each of the 4 Asus motherboard ports and there is no instruction on what port to use. I experimented with 1 ram bank and it book only if the bank was on port 1 of port 2.
What do u need from the bios?
what info do you need from me?

what i would do first is not using XMP Profile and set voltage for VCCIO and VCCSA.
In my case VCCSA jumps with XMP Profile to 1.35V - too high VCCSA can cause stability problems
depending on your CPU (memory controller), Board and RAM you have to find working voltage for VCCIO and VCCSA, sometimes it is good if they have the same level, in my case i need VCCSA >70mV than VCCIO
For beginning i would check how far you can get with VCCIO and VCCSA @Stock voltage (should be 0.95 and 1.05V) but set them by yourself - do not use "auto" and after that you can use XMP Profile and start with let`s say 2933MHz - then give more speed until you get stability problems. I think you will need ~1.05V VCCIO and ~1.15V for 3700MHz, or maybe 1.00V and 1.10V or 1.15V and 1.15V.
If pc is booting and windows starts with 4000MHz next step testing the ram with the tool memtest - i would say open it 8 times (or 16 times) and give every memtest 1500mb to test. let them run up to 200% and an error is not allowed. stable voltage setting -> reducing secondary and tertiary timings for higher bandwith and lower latency. for checking this you need aida64xtreme and do the ram bandwith and latency benchmark. and of course you need memtest again for testing if your new timings are stable. uncore OC means also testing with memtest, higher uncore clock means lower ram latency.
your kit should be single ranked - good for high oc - you can check for B-Die BGAs and if it is single ranked with thaiphoon burner
(for 24/7 use i would not go above 1.25V VCCIO and 1.30V VCCSA)

But should't this ram reach 4000 mhz by stock without passing though the overclocking?
I can't even reach 4000 mhz by stock ....
My pc does not boot if the ram is set past 3700 mhz
