One good thing i have to mention is, that i had no problems yet to wake the system from standby-mode nor did i have any problems that occured with BIOS 0904. BUT I went to do the shopping and put my system or tried to put my system into standby-mode, but it never did. This is a strange behaviour.
I was talking with a guy “Wei Liu” about these issues and he told me that increasing VTT voltage may help here. He just heard of it or read it somewhere. So i decided to increase voltages. What i didn’t mention yet is, that with BIOS 1004 i tested only with stock-settings the first days. Now when i will run the system oc’ed i’m going to apply the tips. Results coming soon.
Asus Deluxe BIOS 1004 released in the end of October
I’m currently testing the Asus Deluxe BIOS 1004 they obviously released already in october. I didn’t notice that. However the first 3 tests were successful. Which means the standbymode, that i mentioned in a previous post with BIOS 0904 (and earlier), did work properly with 1004 (… to their Downloadpage) so far. But the last test is pending. The standby-problem tend to occur, when the system is cold, what indeed is currently not the fact. Even a 10 minuten power-break doesn’t simulate a cold system correctly. I have to wait, then when i wake up the next time to proceed with it.
Few words about the previous BIOS 0904
By time passing by, i experienced some other problems with the previous BIOS 0904. Once it happend that the system forgot about the Boot-Settings. Another strange situation came up, when the system started on its own after a clean shutdown.
I will try observ this too for sure on the new BIOS 1004. Or lets say, you can’t ignore these mal-behaviours since your perception can’t elude these.
Quote “According to Intel’s presentation at IDF, the new Haswell processors enter a sleep state called C7 that can drop processor power usage as low as 0.05A. Even if the sleeping CPU is the only load on the +12V rail, most power supplies can handle a load this low. The potential problem comes up when there is still a substantial load on the power supply’s non-primary rails (the +3.3V and +5V). If the load on these non-primary rails are above a certain threshold (which varies by PSU), the +12V can go out of spec (voltages greater than +12.6V). If the +12V is out of spec when the motherboard comes out of the sleep state, the PSU’s protection may prevent the PSU from running and will cause the power supply to “latch off”. This will require the user to cycle the power on their power supply using the power switch on the back of the unit.”
Also check out their forums (http://forum.corsair.com/v3/showthread.php?t=118456). Possible that you need a new PSU but at first you could try to disable C7 state (if possible) in your BIOS settings and see if it helps.
When i put my system into standby or suspend mode i can’t really wake it from there. When i try to wake it: the hardware responds, fans are starting to spin, harddrives etc, but the system is not really recovering from the standby mode, instead the system goes to Q-CODE bF and sits there until it starts to reboot automatically. Even a 4-sec-press-hold the power button doesn’t help to cold boot the system. The system sure goes down, but it does keep the system to do the bF loop. It keeps infinite (re)booting.
The first thing i did was CMOS reset but it is NOT necessary!
Instead: turn off your power supply wait a few seconds and turn it on again. Then the system should boot normally.
I already did play with some BIOS settings and there was something strange happening when i enabled ASPM Support in “Advanced->Onboard Device Config->ASPM Support” ….
When i enabled ASPM Support, i was able to put the system in suspend/standby mode and wake it with either keyboard or power button, right on the first attempt. This made me think i found a solution. It did work 3 times in a row. I then wanted to know if i can reprocude this by undoing the changes to see the bF code again and redoing the changes to see a working standby mode, and failed. Disabling and reenabling ASPM Support didn’t come up with a working suspend/standby mode.
Asus Technical Support
I already wrote to Asus Technical Support and the first “conclusion” was, that i may have defect hardware with the aim at power supply.
Do you have same or similar problems? Different Q-CODE? Let me know!!
Update: Well sometimes its working and sometimes not. And when i try to record it with a camera, take a guess, its working…. to be continued
