How do I use 3200 Mhz RAM ?

post #1 of 13
Thread Starter 
Hey everyone,

In my recent post:
System keeps crashing after ASUS x-99 PRO BIOS update
started on 07/06/16 last post 07/09/16 at 7:22am 8 replies 144 views
I was talking about an error that occurs once I upgraded my BIOS.

In this post I wanted to make sure what the proper way is of using 3200 Mhz RAM.
For now I am using a X.M.P Profile.. but I am not sure if that is enough.. since my CPU speed is still at 3.50Ghz, wich is the stock speed.

This is a screenshot of the current configuration:



I also tried to use the EZtuning wizard wich let me with the error: Overclocking failed

I hope anyone has some suggestions, since I have been curious about this for a long time.

The hardware I use is:
CPU: Intel Core i7-5930K / 3.5 GHz
RAM: Dominator® Platinum Series 16GB (4 x 4GB) DDR4 DRAM 3200MHz C16 Memory Kit (CMD16GX4M4B3200C16)
GPU: ASUS STRIX-GTX980TI-DC3OC-6GD5-GAMING
Motherboard: ASUS X-99 PRO

It's odd you got an error saying overclocking failed but it is generally better to manual OC. I never recommend auto overclocking as it typically allots way too much voltage to maintain stability. As far as setting XMP that is all that needs to be done. I generally like to set my timings manually to match XMp but it doesn't matter which way you do it.

Hmm... I am wanted to try the manual settings aswell.. do you have any recommended settings I should use for my configuration?

I also saw a friend of mine wich has almost the same configuration as mine that he set the CPU strap to 125MHz and so the BLCK to 125

That is how you use 3200 MHz RAM, your CPU speed is independent from the RAM speed. Notice the memory frequency reported to the right in your screenshots.

If you wanted to overclock your CPU some more you could change the 37 in your first screenshot to 40 or even 42+. Maybe change the cache min and max from 31 to 36-40 as well.

Sometimes the auto voltages are quite high after overclocking above about 42 on the CPU and 38 on the cache, if I remember correctly, so you might scroll down in that menu and try playing with voltages to reduce power/heat if you want to try for above those multipliers. There is a lot you can do to tweak a 5930K on a X-99 Pro, how far do you want to go?

Don't use a high CPU strap with 3200 MHz RAM, that is for 3000 MHz RAM. In my experiance a high CPU strap doesn't work that well on Haswell-E, unless you are seriously tweaking and testing everything to the max I never recommend using a >100 MHz CPU strap.

A great manual overclock that should be easy to do on your system is set XMP then change:

Core ratio from 37 to 42
Cache ratio from 31 to 38

Set voltages to:
Core: 1.25V
Cache: 1.2V
SA: 0.960V
Input Voltage: 1.9V

Everything else can probably be left on default/auto. The correct voltage is the lowest possible that is still stable, but this is different for each CPU. These are probably a safe starting point and because the overclock isn't too high most 5930K CPUs should be stable with these settings and voltages. The System Agent (SA) voltage is somewhat complicated and small tweaks up and down can sometimes help stability, 3200 MHz is quite fast for Haswell so you might need a bit more voltage here. Don't go over 1.02V for SA.

Thanks alot! You are a big help.. I just tried to look for the 125 MHz straps.. and tried it but you were right its only for different MHz values for the RAM. That is also the reason why I had the overclocking failed error.

Thanks for the tips! thumb.gif

I am kinda new to all of the tweaking stuff.. So I am happy that you could guide me a bit through it rolleyes.gif

edit: Is there also any program I can use to see if my RAM is working properly with the X.M.P profiles you use? Since CPU-Z doesn't detect my overclocking for some reason

Hello
If you are interested in learning the platform further you could read my input in the thread linked below:

http://www.overclock.net/t/1590051/xmp-issue#post_24859136
It is a response to another user but with a similar issue as yours and having linked it to similar threads it seems it has helped more people in the last months too.

I am on mobile right now getting ready to sleep and I wont be able to answer to you for some hours so I hope it is enough help in case you decide to give it a read.thumb.gif

Thanks alot, I really appreciate the help smile.gif .. This is really something I was looking for. Can finally learn something about OCing.
