ASUS Z77 Motherboards - Official Support Thread

Hmm if trying to flash in DOS it won't let me saying there is an unsupported bios policy

Looks like I will have to RMA

Raja:
When will the bios for Asus Z77 v-Deluxe supporting IB? I have bios 1050 and it shows that I have an SB-C1 (I have IB E1)

[Eldonko]

Is there any reason I shouldnt have LN2 mode enabled under H20? I enabled it a week ago when benching and left it.

Hm, running into a strange issue with my 3770K. Right now stable at 1.35v for 4.85 GHz but if I try and bump it up to 4.9 GHz or more, Win 7 will boot up but fails to display the login screen no matter how much more voltage I give the CPU. Temps are pretty decent at these settings, low 60's in Prime95. Seems like the Windows 7 login screen is creating a wall for my CPU at the moment for some reason. Using a M5G, any thoughts?

[Raja@ASUS]

Enable CPU PLL OV and try again. If that along with Vcore does not help, could just be the CPU.

AS I said in the PM, 1050 fully supports IB. If you are seeing that somewhere, then it is a misreport.

Updated Fan Xpert module for AI Suite, fixes auto load profile on Windows start (it should be up soon):

Man, when my 3770K reaches 4.89 GHz it falls off a freaking cliff. At 4.88 GHz it is stable as a rock at 1.35v yet going up to 4.89 GHz, no matter where I put the vcore, pll, llc, or any voltage will get it to boot up into Windows. Very strange, I've never seen a CPU behave like this over decades of overclocking. It's like there is a clear-cut no-go line with this CPU. :headscrat

Granted, 4.88 GHz running nice and cool at 1.35v isn't that bad, but I don't understand this limit.

It won't hurt anything to have it enabled. I run mine that way while testing. Just don't use the LN2 settings without extreme cold.

Will ASUS be releasing a Z77 ROG eATX board (non small board)? Something like the commented MAXIMUS V FORMULA I saw once in a site?

[Budwise]

Cant wait to see that 6970 bios fix....

Sandybridge was like this, too. First IB I have heard of with it that drastic.

Formula some time this month or early June.

That's great. Thank you Raja.

sry for going offtopic here but the startup bug with flashed hd 6950 to 6970 does also concern p67 boards like p8p67 since uefi 3207 and obviously all p8 boards since latest uefi releases. me and others reported this issue at official asus support forums but staff there did not comment.

http://vip.asus.com/forum/view.aspx?...Language=en-us

I have also made an offical trouble ticket but german ASUS support tries to make me a fool.

Raja, would please be so kind to report this also to ASUS HQ?

thanks a lot in advance

[Budwise]

Considering Shamino fixed the bug in an hour or two of it being reported on the M5Gene id really like to see this fixed sooner than later.

[Raja@ASUS]

HQ are already aware of this, they will implement a fix in one of the upcoming BIOSes - don't have a timeline on when that will be ready.

[Budwise]

Thanks for the update.

I've had a little niggle with USB detection on the Z77 V LX. Keyboard/mouse plugged into the hub on my Dell U2412M aren't detected at BIOS level, but are detected once I'm in Windows. this only occurs when the hub was connected to one of the USB2.0 back ports, when I switched to a different port the problem's gone. It is of course, not particularly important to me, and easy to work around.

Additionally I had the PC shutdown when I enabled EPU in BIOS, immediately, and refused to POST. Memcheck did get it to post once, but after that no go. CMOS reset restored things. I've not gone near that setting again!

Using 0607 for both of these things.

Edit : Also your new fanxpert software is really quite good, a massive step forward. However the power fan header doesn't get the same love that chassis 1 and 2 get. Could that be added?

1) Not sure on if that can be patched quickly. Depends which port the issue is on. Some of these Dell monitor hubs leak DC so they are essentially non-compliant. Whether or not that is causing issue here I am not sure.


2) Sounds like memory incompatibility. Not sure what you are using as your post is limited in details. Contact ASUS UK suppport for further assistance on that.

3) Fan header support will be limited by hardware, so this will not be a software update.

Hi Raja,

Thank you for your previous advice. As you suggested I have RMAed the Sabertooth and now have a new sabertooth board and all is working correctly. Onboard graphics is back and all the ram slots work. However I want the best overclock possible so would like to update the bios but am concerned about the megaraid card.

Currently I have occupied

Slot 1 PCIx 3 16x 7970 HD
Last slot PCIx 2 (@x4) Megaraid 9260-8i

If i update the bios to the 1050 bios you posted earler will I lose the megaraid?

Thank you again

[Raja@ASUS]

I have no idea on the megaraid card, I have never used one on these boards and don't have one here I can test. If you are concerned on using stable BIOSes then stay on the official qualified builds on the ASUS site.

hi,Raja

I have a P8Z77-V Pro
I'm wondering if my mb will have the same ram oc ability as the M5G with the coming new bios?
I mean M5G has a lot of beta bios and some of them increase the ram oc ability or stability,i'm not asking for the 'memory presents' function,just those changes to the bios that increase the ram oc ability or stability.
