ASUS Z77 Motherboards - Official Support Thread

Did you make it to the desktop on that run, video ended as the OS was loading. Double-BOOT from power cycle can happen after a certain point depending on some fo the UEFI parameters. Also, can you try disabling MRC Fast Boot in the DRAM timing section of UEFI.

Sorry RAJA. No I did not make it into OS that time. It never does after a boot like that even if I never turn off the power. But that is one way that I can replicate it, by taking away power. Bad PSU?
Yes I will disable MRC Fast Boot. Thanks for all the help!!!!
I also Tried Kingston 4GB Kit at 1.66V. That did not work either after taking power away.
If I keep power to the system, it still has the issue of no boot.

[Hondacity]

you set the ram speed to 1600 @1.5v ...this never worked for me.

try auto ram speed and 1.65v on the rams. or 1600 and 1.75v

If nothing else helps, PM me a complete parts and config list and include memory module part numbers. I will pass the info on for replication and see what we can find.

Thanks for all the help. I decided to try a different brand of motherboard. I am having 0 issues at 4.5 on this motherboard. Thank you for all the help. I will continue to support Asus in the future.

[Hondacity]

that doesn't help. share your findings tsk tsk.

[THUMPer]

No amount of RAM voltage or RAM speed fixed my issue.
I eventually just gave up. That was my finding... I went with an MSI Z77A GD65 picked up at my local FRYS. Price wasnt an issue here.

I understand what you are saying, but there is not always value in having timings adjusted so far even from a raw performance perspective. It depends what you deem valuable. It may not be tRC that is causing the instability anyways, so that is why I said we will check first and it is also likely why it may have been left out due to not adding anything. If the margin between needing a high tRC versus a slightly lower clock frequency are not large enough, the additional delay to tRC is of no real benefit.

Any updates yet?

[Raja@ASUS]

Any updates yet?

Any updates and I will post them. If we are going to add it (i doubt we are), it will not be for a while. Next series of updates is already in the works and this is not a high priority as we dont think it will make any real difference in terms of performance.

hey, has anyone tried the M5G with the 30nm Samsung kit?
I wonder how fast they scale in the memory speeds list.

[Raja@ASUS]

The board has a profile for Samsung. Depends how good the kit and IMC really.

as Raja stated it is cpu dependent however most of them should be able to do 2600 11-13-13-35 at reasonable (1.65v) for benching.

24/7 use I have no idea.

[l0ud_sil3nc3]

I just dl 0881 and the extension is .CAP, show a noob how to extract/use this bios file

[bito]

Rename it to .rom from .cap and flash

Use EZ Flash 2 from UEFI. No need to rename.

thanks guys, I had accidentally copied the file to a non FAT32 formatted usb drive hence why it could not read the file, all is well now

Hello. Just bought a P8Z77-V + 2500K and for 4500 mhz i used 1.36V. Dunno if it's too much but with lower voltages i get blue screen random. I have one question also, compared with other mainboards i dont see the "VCCIO Voltage". I dont think this influence the performance of my pc but it would be nice to have it there in case i need it for ram

Think it's tied to SA, so use that to adjust. So, this won't be made into a separate item as it's tied hardware. Your Vcore is about average for that speed, so seems fine to me.

@Raja,

after spending some time writing an elaborate description of my problem with the M5G, I realized I posted it in (maybe) the wrong thread.
I'll appreciate it if you could stop by there and check the pictures and details.

My apologies for the trouble Sir, I realized I posted it in the wrong place only after posting it..

[Raja@ASUS]

You have hit the classic Sandybridge wall. These CPUs are not like older architectures. These first-gen ring bus CPU architectures hard-wall from being near 100% stable to completely unstable. Some CPUs top out even lower than yours.

[NoGuru]

I have the Gene, and just started playing with it a bit last night with my 2500K. Definably has a lot of features and is quite impressive. Can't wait to get an Ivy and some LN2 on this board.
I did have a problem trying to run an 8800 GTX+ on it though, actually tried two cards, two cables, two monitors and the only thing that it would recognize was the on board HDMI. I set it to PCI-E in the BIOS but still nothing. Any thoughts?

[Raja@ASUS]

No ideas, not sure anyone has tested cards that old at HQ during validation.

[NoGuru]

Well looks like I will test a 570 GTX and see if that is the problem.

Thanks.
almost spooky how easy this board is to OC.
it got tired of the 2500K in less then half a day
a true piece of engineering. I'm SO glad I decided to go on this board.
