PC crashing after RAM upgrade

jbrighton · Oct 21, 2016

Yesterday I upgraded the memory on my motherboard (Gigabyte GA-F2A55M-DS2) from 4GB to 16GB, using two Corsair Vengeance Pro 1866MHz 8GB modules.

Today I've already experienced two BSoD. It's been so long since that last happened to me, I wasn't even aware that the Blue Screen still existed!

What is causing this, and is there anything I can do about it?

I am running Windows 10 Pro x64.

Thanks.

Hi jbrighton

Have you updated your BIOS.? What CPU are you using.?
Bios updates are very often required to support DIMMs that were not originally listed on the MB QVL. I have checked and could not find any 16GB x 1866MHz modules on the list of tested DIMMs.
They may or may not work without Bios intervention for Primary Timings and Voltage.
You can obtain your SPD info for your XMP profile in CPUz from within Windows. Write down this info and manually enter the Primary CAS Timings and Voltage in Bios.

Thanks for your reply, MeanMachine!

CPU-Z gives me four different columns under the 'SPD' tab - JEDEC #1 (457MHz), JEDEC #2 (533MHz), JEDEC #3 (666MHz) and XMP-1866 (933MHz), each with different values (and the same voltage, 1.35V). Which one do I need? My CPU is an AMD A4-5300.

Edit: I also noticed that it says the maximum bandwidth is PC-10700 (667MHz0, which is weird, as it is meant to be PC-14900 RAM). Admittedly, I don't understand much about the hardware side of things, so all this doesn't mean much to me ...

Normally I would enter values for my XMP profile in Bios.
Go to Channel A/B Timing Settings in Bios and enter the Primary Timings.
This sub-menu provides memory timing settings for each channel of memory. The respective timing setting
screens are configurable only when DRAM Timing Selectable is set to Quick or Expert.
Try your XMP profile at 1.5V as listed by Corsair and they have also listed them as:
Tested Latency: 9-10-9-27
Voltage: 1.5V

If these settings still cause the system to BSOD then we will have to analyse the dump file in case its something else.

I just had a look at the BIOS, and I wasn't able to change any of the settings.

XMP - Disabled
System Memory Multiplier - Auto (and couldn't be changed)
Memory Frequency - 1333MHz (greyed out)

Profile DDR Voltage - 1.35V (couldn't be changed)

There is also a setting for Profile VTT Voltage which is set to 1.05V and which was greyed out.

The latency settings are 9-9-9-24. I wasn't able to change any of the values.

What can I do now? BIOS Update? CPU-Z says I've got AMI version F3 from 28/09/2012.

jbrighton :

Did you change DRAM Timing Selectable field to Quick or Expert.?
Latest Bios is F7c so you will have to update. Do you know how.?

jbrighton · Oct 21, 2016

Yes, I tried both the Quick and Expert settings, same result with either.

I've never done a BIOS update before. If you can tell me if there's anything that I need to be aware of, I'd be very grateful.

Thanks.

I'm feeling pretty apprehensive about doing something as extreme as a BIOS upgrade, as I'm worried that somthing might go wrong and I won't be able to boot into Windows again - but so far I've been working non-stop on my computer for the past eight hours or so without any more crashes, so hopefully I'm not going to have any more problems ...

Fingers crossed and thanks for your help!
