Computer freezing after CPU upgrade

Ante Pavelic · Jan 16, 2015

Recently I upgraded my CPU from an AMD FX-6200 to a 8350. All my drivers and BIOS are up to date, everything ran smoothly. Until my computer froze while watching a Youtube video. Didn't think much of it, just hard reset my computer and continued on. My computer would then crash again while browsing the internet, another time while Skyping and then another time while doing a system scan using the advanced system care 8 program. Really fishy, I thought I had to reinstall Windows. And so I did, until I then crashed several times while redownloading all my stuff. My question to you guys is, what could be causing this? I'm starting to think that my CPU could be faulty.

I don't blue screen. My screen just freezes with not being able to do anything. Also, the computer doesn't seem to crash when playing video games, for some strange reason.

Specs: Sabertooth 990FX GEN3 R2.0
AMD FX-8350
EVGA GTX 780ti
GSKILL F3-12800CL10D-16GBXL
AX860 PSU
2 Samsung 840 Pro SSD
1 magnetic drive I don't remember the name to

can you try an other psu? maybe from a friend.. or...
can you check in the bios if all the setting is on the default setting?

badboyrog2 :

No, I can't.
I'm assuming you mean under CPU?

badboyrog2 · Jan 16, 2015

in the bios about the voltage setting...sometime for any reason the bios is set on overclocking...
do you installed an overclocking software?

Ante Pavelic · Jan 16, 2015

badboyrog2 :

voltage is all set to auto, cpu & nb voltage is set to offset mode. ( not sure if that means anything)
I don`t have any overclocking software.

Update the BIOS to the newest version. There are known issues with the Sabertooth board using FX8 chips on older BIOS versions.

Darkbreeze :

My BIOS version is 2501, which is the latest. Should I do it again?

Should I update the chipset maybe? Would that even do anything?

Darkbreeze · Jan 16, 2015

If you already have the latest version, then that isn't the issue. Try going into the BIOS and resetting to optimal defaults.

Darkbreeze :

Well, when I rebooted from going into the BIOS, my computer crashed when it loaded in. So, that might not of been it or maybe it was just a freak accident. I will see how it goes from here on out.

Any other suggestions maybe?

badboyrog2 · Jan 16, 2015

try with only one memory stick
or maybe trying to reseating the cpu..and check for the cpu cooler installation issues..thermal paste

Darkbreeze · Jan 16, 2015

When you reinstalled the CPU, did you connect the CPU fan to the CPU FAN header or the CPU OPT header. Make sure it's connected to the primary CPU header.

Darkbreeze · Jan 16, 2015

What are the model numbers of your memory modules. Speed, etc.?

Ante Pavelic · Jan 16, 2015

Darkbreeze :

These are the ones I have http://www.gskill.com/en/product/f3-12800cl10d-16gbxl
Also, the CPU fan is connected correctly.

Darkbreeze · Jan 16, 2015

Try manually setting the memory profile in the BIOS. It may be defaulting to an automatic setting that is incompatible with your memory and CPU. Make sure speed, voltage and timings are all set to the actual memory profile for the module. If a preset profile like XMP is available, you may try that. Those modules have preset profiles but I can't remember if the XMP profile setting is present in that BIOS. You may need to set them manually if they are not automatically being set correctly.

Ante Pavelic · Jan 16, 2015

Darkbreeze :

Where is the memory profile located exactly?

Darkbreeze · Jan 17, 2015

First you will need to enter the BIOS, press F7 to enter advanced mode, go into the AI Tweaker menu and set the memory speed to 1600 or whatever your modules are supposed to be at. Next you'll need to go back to the AI tweaker main menu and go into Digi power menu. Make sure the Dram voltage is set to 1.5v. Save settings and reboot.

Ante Pavelic · Jan 17, 2015

Alright, speed is set to 1600mhz, and the voltage set to 1.5v.
Will update if this works.

Was set to 1333mhz before and the voltage was auto.

Ante Pavelic · Jan 17, 2015

Bad news, it didn't work. Crashed today after it being up for a long time, longer than usual.

Checked my BIOS to see if the settings are still the same, they are. Although the voltage is at 1.49v, I'm assuming that's the same as 1.5v correct? Even though I do have the voltage set to 1.500000v.

Darkbreeze · Jan 17, 2015

Check the latency timings make sure they are set to 10-10-10-30-2N. Might also increase the Dram voltage a notch. What are the timings set to currently? You can check them in CPU-Z on the memory or SPD tabs, forget which those are on offhand, or in the BIOS under the memory settings.

Those are the results from CPU-Z. As to switching them in my BIOS, I will need help on that account as well

Darkbreeze · Jan 17, 2015

So leave the modules at 1.5v, as apparently the JEDEC profile indicates it to be correct.

Under the AI tweak menu in BIOS, look to see what the primary timings are set at. These should be listed as:

DRAM CAS# Latency (something between 5-19)

DRAM RAS# to CAS# Delay (something between 2-19)

DRAM RAS# PRE Time (2-19)

DRAM RAS# ACT Time (8-40)

DRAM COMMAND Rate (Auto, 1T or 2T)

These are the values, do they need changing?
Also, as a side note if you don't already know, I'm massively grateful for your continued help!

Darkbreeze · Jan 17, 2015

No problem at all. That's supposed to be the point of this forum, although some members occasionally lose sight of that.

I would manually set those first four to 10, 10, 10, 30, in that order.

I don't see the Dram command rate listed, so scroll further down until it appears and see what that's set at.

Ante Pavelic · Jan 17, 2015

Darkbreeze :

It's all the way to the bottom on the bottom imgur link, it's set at 1T

Darkbreeze · Jan 17, 2015

Ok, I think you want that one set at 2T.
