Intel Core i5 3450 freeze and Gpu artifacts on screen

Hi guys,

Since when I build my pc 4 months ago ithad sometimes freeze and a sound very weird, then did some testing with memtest86 + for RAM memory, cpu stress tests and all had satisfactory results, no error has occurred. I thought it was the adobe flash the culprit, because every time I crashed when watching videos on youtube, I started using the html5 and freezing constant problem stopped. But still, once in a while itstill fought. What caught my attention is that these crashes to reset the pc, and then he hung up completely and them Power on.

Currently, the problem came back, and this time very randomly, sometimes it happens when I'm playing games (Warcraft, Need for Speed, Skyrim...), watching movies or videos on youtube, it happens 2 things:or the pc hangs and artifacts appearing on the screen,or the pc restarts in the way I described earlier.

I decided to do a more detailed test, because this is really bothering me.

The tests:

-FurMark to stress the GPUs (onboard and offboard)

Result: In the offboard gpu test was a success without any error, since the onboard video, the pc crashed with less than 1 min test as can be seen in the link below:

-Memtest86+ for stress test on Memory Ram

Result: The program spent with my 2 sticks of memory, and then each separately and in different slots, by 6am. No errors were found.

-Prime 95 to stress the CPU

Result: no error also.

I decided to leave the pc with only 1 stick of memory already onboard video that showed the error very quickly, and to my surprise the pc worked a full day without locking on, redid the test Furmark for 4 hours and monitoring the temperature as the RealTemp. The maximum temperature in one of the colors reached 47 º C only.

This procedure made with the two memories sticks , one at a time, and PC was actually stable.

When I put the 2 sticks of memory in PC (dual Channel), problems reappeared:

With the offboard GPU these errors happen more also a much smaller scale, with the onboard happen very often.I suspect that might be the processor, but would like the opnion and suggestions to solve the problem.

My configuration:

Intel core i5 3450

Asrock Z77 Extreme 4

8GB gskill sniper 1.25V (http://www.gskill.com/products.php?index=390 http://www.gskill.com/products.php?index=390)

XFX Radeon HD 4850 512 MB

HD SATA-3 500GB seagate barracuda

HD SATA-2 1TB Samsumg

PSU Seasonic 520W 80 plus bronze

Windows 8 Pro

Sorry for the long text and bad english.

Hi pedro_bruno,

Reviewing your system configuration listed, we can see the memory you have was tested to run at 1600 MHz, 1.25 V. Have you run compatible memory? The memory controller specifically supports whether it is 1333 MHz or 1600 MHz, at 1.5 V only. Please find the memory specifications at the processor data sheets, page 11: http://www.intel.com/content/dam/www/public/us/en/documents/datasheets/3rd-gen-core-desktop-vol-1-datasheet.pdf http://www.intel.com/content/dam/www/public/us/en/documents/datasheets/3rd-gen-core-desktop-vol-1-datasheet.pdf

For troubleshooting purposes what you may want to do first, is test compatible memory. If this does not work, you may want to make sure your motherboard already has loaded the latest BIOS version for a proper processor recognition. Also, you could go ahead and update your motherboard drivers.

If the memory is fully compliant with the memory controller specifications, the latest BIOS version and motherboard drivers are loaded and the issue persists, we recommend you contacting your local support group for further assistance on your issue: http://www.intel.com/p/en_US/support/contactsupport http://www.intel.com/p/en_US/support/contactsupport

Thx for answer me!

That is correctly, but in the Asrock's memory support list http://www.asrock.com/mb/Intel/Z77%20Extreme4/?cat=Memory ASRock > Z77 Extreme4, my memory (F3-12800CL9D-8GBSR2) is listed there.

Should I set the memory to run a 1600 Mhz and 1.5V?

Following the hint provided for Intel_Karla, i changed the voltage of my memory for 1.30v and the system run all day, without freezing.

I performed memtest86+ for 3 hours and no errors, and furmark for 2 hours no errors either.

I will continue perform tests and i will keep you in touch guys.

Thx for help
