Got DDR4-3000 RAM running at 2333mhz, XMP isn't working, help?

post #1 of 5
Thread Starter 
So I bought Corsair Vengeance DDR4-3000 RAM which needs XMP enabled to get it to that 3000 I think. I just tried to turn on XMP and it shows a profile but doesn't apply it, here's the dataL

CPU Core Voltage 1.216V
CPU GT Voltage 0.008V
CPU SA Voltage 1.120V
CPU IO Voltage 0.960V
DRAM Voltage 1.200V

(these are all set to auto and that's what they are)

XMP profile by default is:
DDR4 3000MHz 15-17-17-35 1.350V
not sure what that means but OK, I enable XMP and reboot with it all on auto...

lots of screen flickering (I am using integrated graphics btw, right now, until GTX 1070 stock comes)

Some people suggested faulty RAM, I think it's settings before I ask for a replacement

Here are the automatic after settings:

CPU Core Voltage 1.216V
CPU GT Voltage 0.008V
CPU SA Voltage 1.280V
CPU IO Voltage 1.260V
DRAM Voltage 1.360V

(again, still on auto)

Lots of screen flickering now

What can I do here guys? Thanks for any help.

How many modules and whats the capacity of each? It is possibly that your CPU's memory controller is not strong enough to run such an amount of RAM at such a high frequency.

E: Did not notice the link. No idea why it is not working as intended. 16GBs (2 x 8) at 3000MHz should be manageable for a 6700K.

I suggest dropping your CPU SA Voltage (this is the memory controllers voltage) by ~0.100V to ~1.160V. This is what I run on my 6700K@4.7GHz for two 16GB sticks which otherwise are exactly the same as your's: Corsair Vengeance LPX DDR4 3000MHz 15-17-17-35 1.350V. Auto tends to use very high voltages for some reason and I get better stability at lower voltages with less heat/power.

I also use 3200 MHz instead of 3000, 3200 is, surprisingly, slightly easier for the memory controller so it is sometimes more stable than 3000 (if your RAM is good enough but the memory controller doesn't like 3000 with that RAM tongue.gif), it is also faster. Try 3200-16-18-18-36 if you have any trouble at 3200-15-17-17-35.

Just a little confused here.

You said drop CPU SA Voltage by ~0.100V to ~1.160V - 1.160V is higher than what my current voltage is so I'm a bit confused here. What do I drop it by and to?

How do I set a memory profile?

I thought you were using the Auto settings for voltage now? The XMP settings look good to me. You should be able to manually set the numbers somewhere in your BIOS, sorry I don't have that motherboard and haven't used an MSI board recently enough to remember where you set these things. redface.gif

Look through the settings pages, it should be pretty obvious once you find it. smile.gif
