*** ASUS Sabertooth Z77 official thread - info, BIOS, preview, review etc.***

For those of you overclocking using the main multiplier and offset voltage you will need to disable "Asus Multicore Enhancement" if you want to take advantage of Intel speedstep. If you leave "Asus Multicore Enhancement" enabled your CPU will not clock down during idle periods.

It's years since i've had an ASUS board so it might be common knowledge, but it was just something i came across after overclocking my 2600k.

What exactly does that setting do anyway? It's not in the manual and the description in the bios is pretty vague.

i think i allow to modify multis and all via ai suite...but not sure

New BIOS out for the Sabertooth @ ASUS

SABERTOOTH Z77 BIOS 1015
1.Improve Improve system stability.
2.Enhance compatibility with some USB devices.
3.Support new CPUs.'
Please refer to our website at: http://support.asus.com/cpusupport/c...Language=en-us

It justs locks your CPU at your specified frequency.

It's worthwhile turning it on if you are benchmarking seeing as it stops the CPU from downclocking, but for 24/7 use it's not needed.

Picked one up with a 3570K. Have tried MNH-E Hypers and Micron D9PFJs with up to 1.67Vdimm and loose timings (10-10-10-30-3T) and cant get it to boot Windows with memory at 2400Mhz. 2200Mhz 9-9-9 or better is no issue though. Is there some other timing preventing it? I didnt think the D9s could do 2400, but the hypers should be able to, right?

[Leeghoofd]

Not with 1.67 Vdimm mate, I think they need 1.8+ VDimm

I can do memtest 2400c8-8-8-27 1T at 1.75 with my GTX2 set, yet hardlock at Pi 2M loooool... need a gene board to have access to some of the magical timings

[Cecil]

Got a set of Sammy 30nm, and still cant get 2400Mhz. Pushed VCCSA to 1.1v from .925v, PCH up to 1.15v, vdimm to 1.625v, set timings really loose to 11-13-13-37-2T, and it still wont post. 2200Mhz 9-10-10-28 1.6V is perfectly stable without touching anything else.
EDIT: Pushing the BCLK to 105 with the x22 multi I can get 2310Mhz. The x24 multi just doesnt want to work.

I have my new Sabertooth Z77 with an Intel 3770K, everything is fine, except one thing.

I have a keyboard Corsair K60, and this keyboard is not detected by the motherboard on the startup...
I have to unplug/plug on Windows, and it's fine, but if i don't the keyboard is off...

Somebody else have this issue too with an USB device ?

I've just see the new bios 1015, I will try it asap.

Hi, got everything together today and on firing it up I get RED CPU LED and a constant beep. Disconnected nearly everything and still get the Red CPU LED, beep went away. From computer panel I only have the power switch wired. No Ram, no Cooler, no Vid Cards, no Drives etc.
Using a Corsair 750 Watt PSU which I've had for about a year.
Intel Core i7 3770
Sabertooth Z77.
Noctua NC14
Bios 1015

Would greatly appreciate any help. Saw a similar post on older motherboards and Raja mentioned trying one stick in 4th slot - that didn't do anything for me. Also - I updated to latest UEFI before I ever powered up. Seemed to go successfully.

So i've never seen anything on screen. Freaked out and powered off by holding down power button on all my attempts.

Thanks!

Update - RMA'd the board. Wasn't able to solve using diff power supplies, disconnecting everything, etc. Power/CPU installed properly....
New board worked like a charm.

[djchapm]

I think the thread should be wiped - no activity.

[herderien]

did you checked the cpu power supply (8 or 4 pin) ? did you try the memory compatibility button ?

this looks similar to your issue :

After few investigations it appear the problem are the mouse Steelseries Xai.
Without this mouse plugged everything is okay.

A bit behind, but 1206 BIOS out on June 8.

[jackbrennan2008]

Seems like 1403 was removed from the Asus website for some reason? Anyone know why?

I've still got it installed atm.

[Hockster]

Good question. I downloaded it but haven't flashed yet.

[Durkadurka]

I am trying to figure out what MB to get for my Ivy build, and this definately looks cool.
Anyone know if there will be a Rampage MB with Z77 ?

Rampage = x79 only

[Durkadurka]

Rampage = x79 only

Right, so they are not planning like a Rampage V Extreme or something?
Someone recommended the M5G, but thats too small for me and my use.
I think I'm gonna check out this Sabretooth MB.

And it's back on the website again , same version as was posted before (compared both downloads).

Sorry to say, but the amount of info in this thread is very low compared to other "official" threads
