BIOS 4598 and 5020 have known issues (broken BCLK, multipliers, etc.) ... the last stable release appears to be 4405, which has been running on my system without issue.
I am curious though... when you say that you shut the machine off for 30 minutes, and then it reboots... are you putting it into suspend, or completely turning it off? When I first purchased this board, I started having all types of strange issues... system would not flash BIOS outside of recovery mode, system would not recover from sleep, and occasionally it would boot with the message as you describe. The unlikely culprit was one of my memory modules (even though no errors could be detected if memtest86 etc.)
Based on the excessive troubleshooting i've had to do on this board, I would suggest remove everything that is non-essential to system boot (run single memory module, disconnect extra SATA devices etc.) to see if it will be stable.
Go into the bios / performance / memory overrides/ and turn off the failsafe for a couple of troubleshooting restarts. While there in the bios, set the memory profile to the slowest XMP profile. Make sure that the voltage setting at the bottom of the timings list is set to 1.66v and cmd is set to 2. The Corsair memory really needs 1.66v.
Turn the power off let the box stand 5-10 minutes, try the power up.
That power up, auto down, auto up again, is the failsafe resetting the memory timings to some default pulled out of the Corsair memory.
And it gives you a heads up via that error message that it thinks the first memory timings won't work. ( even tho it's not very clear - Intel? )
PS The Corsair memory really needs 1.66v and it's not too much for the cpu.
I turned off. If I turn off the system for 5 or 10 minutes than it starts normaly. The issue occours when the system stays off for a longer time, eg. 30-40min, ok?
I´ll try what you said. In this moment i´m trying to change de Sata slots. I was thinking about the Watchdog failsafe (I don´t know what is the Watchdog) but think that it´s what´s causing the auto down (10 seconds) when I start the system. Will try and post the results here later. Thanks to both of you guys!
tex2xx, I found the failsafe but couldn´t find the XMP profile and the CMD set to 2 there. Could you help me and say where exactly it´s located there inside the BIOS? Now I´m running the 4405 BIOS Version as Domain said. Tks!
According to the Intel processor compatibility chart the SLBEJ i7 920 needs bios version 4021 or later to run. You need to check your bios rev.
This is due to the D0 stepping cpu, it's a later rev chip build.
Check the your Corsair memory for Core i7 compatibility on the Corsair website.
PS I'm running the Corsair TR3X6G1600C8D on three DX58SO systems with no problems. Win 7 x64.
I´m running Corsair XMS3 TR3X6G1333C9 G 6GB Pack (3x2GB) so I think it realy needs 1,5v instead of the 1,66v that you said before. Your model runs on 1,65v cause it´s a 1600mhz. I´ll disconsider your previous topic. I´ll try only to disable the failsafe Watchdog and post the results here later. Tks!
XMP profile settings are under Performance (Select Yes to allow modification), then Memory Overrides. Select "Performance Memory Profiles" and change from Automatic to XMP (will vary depending on supported modes of these chips).
Watchdog is there to detect if BIOS modifications result in an unsuccessful boot, allowing you to go back into the BIOS and change settings without having to pull the configuration jumper.
I have the same problem.
Just bought the DX58SO, I7 920, Kingston 1333.
It was running fine until I updated the bios to the 5020 version. Looks like it was not tested correctly.
The problems are as follow:
-Core speed was set at 135 instead of 133
-The multiplier shows values that go from 22 (default) to 24 (proposed and active) when the maximum value that can be set in it is 20
As a result the processor speeds go from 2.9 to 3.33 when the processor is originally set to 2.66.
As a result the system is only starting in bios configuration mode.
Loading default setting will not solve the problem. I also removed the battery for 15 minuets.
Please help me fixing this problem.
Intel Please remove the 5020 Bios from you download section, Since it will affect your image.
load the default settings, then go to the performance page and change the bclk to 133. thats all you need to do. there are no other faulty settings afaik.
everything else you list is just a wrong readout from the bios. doesn't hurt your components. the effective settings (that you dont see) are correct.
I did that but the problem persisted, the system would not boot.
Removed battery for 15 minutes.
Boot to windows and installed bios version 4405.
It seems fine now even though multiplier is 22 in bios (21 in windows CPUz).
I´ve called Intel support and the attendant told me to update to BIOS 5020. I did the process but when rebooted the system it wont boot anymore. Tried removing the battery, removing the jumper, setting jumper to configuration mode and nothing.
My mobo is dead. When I remove the memories modules the system give me a 3 beeps, so Intel´s support says that my mobo is not dead, but when trying to make the recovery process it didn´t work. The system wont read the CD/DVD with the .BIO file and wont read the USB too. All i´ve got is a black screen!
Don´t know what to do. Very frustrating!!!
I have the exactly same issue, is there any solve to this?
