BIOS 1001: New problem booting (QC B1)

Grestorn
Level 8
I just updated from 0802 to 1001 because I had continuing booting problems with 0802.

For the time being. I'm using stock settings in the BIOS (only disabling unused components like WiFi, Bluetooth and SATA Express).

Still, after turning off the system, I have the problem that quite often it doesn't boot the next time I try to start it. It hangs with the code b1 which I can't remember having seen with the old BIOS.

Nothing but disconnecting the system from the power source seems to resolve that.

I tried to rise the SA voltage to the "sweet spot" I found with the old BIOS (+0.096V) but that didn't do anything. I don't even want to start to try OC settings unless the system boots reliably with stock settings. Do you have any idea what I could do to resolve this?

Hello

VCCSA adjustments should not be necessary with stock settings. Wheat is the model number of the memory, how much installed and what speed is it running at?

There are 4 4GB modules installed. They're also running at stock speed (i.e. 2133). XMP is not active.

With the old BIOS I was able to clock the RAM with 2800 using XMP without increasing its voltage. I ran MemTest one whole night without a problem.

I'll make another run with MemTest this night, this time with stock settings.

Here are the details about the RAM:

I made a MemoryTest run for two nights in a row (400% coverage) without any error.

Is there any setting that I could change to make the stock settings to boot reliably? Slightly increasing the DRAM voltage? Change one of the Training values? Anything?

I don't want to put more money in the platform right now, I just want it to work reliably with stock setting.

I also want to add, that there are TWO instances during boot, where the QC b1 is displayed: One about a second after a cold boot, in this state the display is not initialized yet, and the fans are still running with full speed.

That's the instance when my system is usually hanging.

The second instance is much later, when the ROG logo is displayed, right before the Win 8 ring of points starts to spin, i.e. when the UEFI turns control over to the windows boot loader. Sometimes it's also hanging there with the same code b1.

Could both be an USB problem as well? I have an internal USB 3 hub and memory card module which is connected to the internal USB connector (http://www.silverstonetek.com/product.php?pid=401&area=en). It's a bit difficult to access the connector for that device, which is why I didn't try to disconnect it until now. But if you say that b1 could indicate an USB problem (which I would supprise me, since it's happening that early in the boot cycle) I'd try to disconnect that anyway.

Try disconnecting every USB device but your keyboard and mouse. Try plugging them into the two USB 2.0 ports

See if that helps. I think it is a USB issue
