Unable to change voltage for my RAM

I can't find a way to change the voltage for my DRAM. I'm sure users have experienced this issue before. Wondering if anyone has found workarounds.

I bought a G.SKill DDR3-2400 PC3-19200 16GB(8x2) RAM kit before actually checking my BIOS. It seems that HP limits what users can change in the BIOS. There is absolutely no DRAM settings, I can't even check what speeds and voltages they are running at in the BIOS. I figure that's no problem, I probably can use third party software to make the changes and see the settings.

I used Intel Extreme Tuning Utility and am able to customize all the timings, but I notice there is no voltage control. As there are so many fields to customize, I just choose to use one of the XMP profiles they have for the DDR3-2400mhz, I figure maybe it would change the voltage also.

After a restart for the changes I go into CPU-Z and check. The SPD tab shows the timing tables for my RAM. I go to check the MEMORY tab and it shows the timings were changed successfully by the Extreme Tuning Utility. Once again, the only thing that it doesn't show is the voltage.

I'm racking my brain to figure out what programs I can use to actually check voltage. I downloaded HWinfo64 and SpeedFan. I still don't see the actual voltage of my RAM. I'm just hoping at this point, since everything booted and is running that maybe the voltage is set at the correct voltage (1.65 volts). I test it out on The Witcher 3 and get the BSOD saying MEMORY_MANAGEMENT.

I test the memory modules with Memtest86 to make sure I didn't get bad memory modules. Ran the test at the default 1333mhz for 24hours with no errors. I changed to the 2400mhz XMP profile in the extreme tuning utility, then test again with Memtest86 and within the first 30 mins I'm already getting errors.

This leads me to believe that the Intel XTU isn't able to change my DRAM voltage to the required 1.65 volts that it needs to function correctly. I've exhausted all the possibilities that I can think of besides modding the BIOS. I do not want to risk bricking the MOBO.

The only thing I can think of now is to lower the RAM to operate at 2133 or 1866mhz with tighter timings. 2133 might need 1.65 volts so maybe 1866 is better.

Has anyone figured out how to change DRAM voltage? At this point, I can't even check my DRAM voltage to see if they are at the correct settings. I think the BIOS has the DRAM setting locked at 1.5 volts. I'm frustrated that I spent more money for higher frequency RAM when the BIOS doesn't even allow me to change the voltage to let the RAM operate correctly.

Why would HP sell a high end gaming desktop and advertise that you can overclock, but not allow users to.

My system:
HP Envy Phoenix 810-430CTO
MSI z97 motherboard (OEM)
Intel i7 4790k
Nvidia GTX 980
BIOS: AMI version 80.13
Windows 8.1

  1. Prebuilts generally always have a locked BIOS so you can't make changes to things like the DRAM, CPU, etc. It's basically you get the rig as is and no changes are allowed for through the BIOS - sorry :(

    I figured that was the case after I couldn't see any settings for RAM changes in the bios. I just figured it a 2016 maybe someone might have found a workaround by now. More importantly, the fact that I can't even see my ram voltage in any third party program is strange. I'm sure there are tons of people that have this exact same model PC. I was hoping they ran into this issue and maybe found a solution.
  3. Sorry, just one of the pitfalls of a prebuilt :(
  4. I'm wondering what frequency and timings would work at 1.5 volts?
