RAM upgrade problems

Recommended Posts

I'm scratching my head on this one...


My Mobo is a gigabyte aorus gaming 7 v1.0 with the original bios installed. I bought it October ish 2017.

I upgraded from corsair vengence RAM (16GB 2x8GB DDR4 3000 MHz 1.35v)


G.SKILL ripjaws V (32GB 2x16GB DDR4 3200 MHz 1.35v)

When I put in the new sticks, the PC wouldn't post with a C1 error code. All it would do was cycle on and off.

I switched out each new stick of RAM and put in its place an old stick. When I did this, it posted. I was able to go through this process to find that one stick would consistently be a problem. 

I thought, ok, this sucks but I will just go back to microcenter and get a new set of RAM.

Well, here's what's puzzling. I put both new sticks back in just to see if it would screw up again. It didn't, it's been running fine so far.

My BIOS also reset it's self to factory defaults on it's own.

I will do windows 10 memcheck when I get home in a couple of days. 

Do you guys think that the sticks truly weren't seated in properly? Or do you think I actually have a bad stick of RAM and right now things are running ok but in the short term, things will degrade very quickly?

Also, I never set the XMP profile to DISABLED before putting the new RAM in. So I guess the Mobo was trying to POST with an improper xmp profile from the old sticks. Do you have to do that? 

Why did my BIOS reset itself? I have to do my entire OC again. Oh well.


What are y'alls thoughts?

A badly seated card is always a possible explanation of a RAM issue, or more likely, a dirty contact or some dirt or other foreign debris in the slot.

Some overclocking mobos are designed to fail-safe back to default/auto values if they fail to POST as configured...that might explain your resets.

The Win 10 memory test is really hit and miss--I'd suggest downloading the free Memtest 86+ utility and creating a bootable USB stick using the supplied program.  Boot into that and run it for 8-12 hours (e.g. overnight).

Motherboards aren't always super-accurate on the voltages actually being supplied to the DIMMs.  Sometimes if the memory is teetering on the ragged edge of stability, adding just a little voltage can get it over the hump...e.g. 1.35v to 1.36v or 1.365v. 

As far as the XMP settings, if you have the BIOS set to automatically use XMP, then it should use whatever XMP profile is written into the installed DIMM's SPD.  If it was manually set using the XMP profile, then it will use whatever you last set in the BIOS.  The exact terminology and settings vary with the BIOS.

It's a Gigabyte that is perfectly normal. It is just verifying the timings of the new ram, now that its up and running make sure you have enabled the XMP profile and it is running at 3200.

I have a Gigabyte board and just upgraded my corsair ram to some faster 4000mhz stuff and it did the same thing. Took about 3 self restart before it was ready to boot up.

I don't recommend doing this but if you were to mess with the timing and frequency settings and get to aggressive it will do the same thing again and restart till it gets to a safe setting again and finally boot up.

On ASUS motherboards you have a MemOK button you press after boot when new memory is fitted this will then put the MB in resetting the memory timings.
