0F4 BSOD

Retired

I have a 2500k OC'd to 4.8Ghz on a Gene-Z board. It passes 24 hours of Prime95 and 20 flops of IBT. While playing movies and streaming videos, I will get a BSOD 0F4 after it's been on for 24+ hours. What is causing this?

Caehlan, I wonder if you did not cross your thoughts here. You say that high performance is default which it is, but that you switched it to Auto which caused multiple and consistent BSOD's.

I am starting to experience the kernel-power error and am considering lowering my OC to default Intel power levels. Auto may not do it but I might bring my system down to normal speed just to have a baseline with a norm vcore voltage.

Windows 7 is completely reinstalled. I don't know if I stated this before but usually it wouldn't happen during a stress test. It would usually happen watching a movie or after being on days and days at a time. I will update this thread when something happens or in two weeks, as it has only ever been up for 1 week before BSODing.

After 3-4 days of being on, my computer gave me the 0F4 BSOD again. It also forgot my boot priority and lost my SSD which is plugged into the 1st sata 6.0 port. I had to clear CMOS in order to get it working again. Did the first thing that you recommended Raja and upped my voltage to 1.15v.

Upping the voltage to 1.15v didn't fix my issue. I got another 0x0F4 BSOD. I am adding the C3 and C6 fixes now.

All fixes that were recommended have failed. Kingston released a firmware update. I am using it in conjunction with the BIOS changes that were suggested.

If this does not work, I am afraid I am going to have to start RMAing stuff.

Let me know what you find!

Sightup.

Fresh OS install, don't tamper with services and check if there is a firmware update for your SSD. In addition to those steps, return the system to stock speeds to debug the problem (dont overclock until the system is 100% stable at stock).

I called Kingston and they stated no new firmware updates are available.

Alright. I loaded the optimized defaults to the motherboard.

I changed the memory timings to what they should be and the boot priority.

I disabled the following:

onboard video standby and iGPUMultimonitor.
USB 3.0 support
EHCI Hand-off
JMB Storage Controller
ASMedia 3.0 Controller
ROG Connect

I am going to now install Windows 7.

Okay, leave it at stock and see what happens. If you get another BSOD, increase VCCIO/SA by 0.05V (to around 1.15V), and if that does not help disable C3 and C6 in the CPU configuration section of UEFI, and see if the issues persist.

I did a lot of research on my SSD. Not many have mine, but plenty have SandForce SSDs. That being the case, 0F4 BSOD can be linked to that so I hope that a new firmware comes out. OCZ just released theirs on the 17th of this month. Kingston shouldn't be that far behind.

And for a side question, what is the max I can up the VCCIO/SA safely for when this is solved and I start overclocking again?
