ASUS Official X79 Motherboards Support Thread

[Marvin82]

Hello I have a question. My cpu on my sabertooth needed 1.33 vcore for 4.8 ghz. Vcore on my Rampage <1.38vcore ? What can I do to reduce it further? Is it the bios or have I forgotten an important setting? The VTT is also 0.1 V above thatof the Sabertooth
Sabertooth 1,13v Rampage 1,25v Vtt 2133mhz cl9?

Why the CPU is running on the Rampage so bad? Bios?

Hi Raja,

having problems running two Intel G2 SSD's (80GB) in Raid 0 mode. Both drives are visbile in Bios as a Raid Array.
When installing Win7 64 the drives are not known and the installing asking for the driver disc. After put the Asus Driver CD in the DVD drive
the installation will not finde the driver.

Any idea?

I have a pretested 3930K which runs on an Asrock X79 Extreme4 4.8 Ghz with 1,344 Vcore (Prime95, 64Bit).
Even with 1,42 Volt the CPU is not running Prime stable on the Rampage IV. I already used Bios 604 and 079B.
This is looking like a Bios issue for me because I can't believe that the CPU need so much more Vcore on the Rampage IV.

Cheers
Lars

Manage to run my 2133C9 to 2400C10, didn't tried 1T. The trick was the tRCD to 12, pi32 at 1.65v:

1) Do those drives have any header information on them from a previous RAID array? If so they will need a full erase and rebuild. As for the drivers if the ones on the DVD are not working you may need to driect Windows deeper into the subfolders to find the file, or download from the ASUS site.


2) Be sure to measure voltage with a DMM from near the socket on both boards to make a full compare. LLC varies wildly between boards.

Measure voltages near the CPU socket under load and then compare volt for volt. VCCSA is needed for memory overclocking more than VTT.

If only doing single 32M runs, then tRTP, tRRD and tWTR can go to 4 clocks. tFAW can go to 16 and tRAS can go to 26. You should be able to shave tWR down to 9 and possibly Write Latency to 8.

[Raja@ASUS]

Another New one

0083b

http://www.mediafire.com/?p29tmaixutz4kju

More DRAM Tuning

Added option under 'Latency Boundary' 'Furthest' - Furthest will help RAM OC higher (especially Elpida Hypers/ BBSE) at the cost of latency.

Added Load Tight 4x4GB Hynix Profile.

Ok thanks for those settings. pi32 is only an example, i'm searching for the max 2400 stable setting. In fact iwould like to buy the 2400C11 kit but if mi 2133C9 can do the job no need to change!

I'll try 0083, for me the 79 is not as stable as the 0075.

[Raja@ASUS]

You cna just load the Hynix profile in 83B then Pinto. Does all the stuff for you, then experiment from there

[pinto]

It works great but if i want to reduce tRCD to 10 i have to raise vddr so i stay at 11. First time i have so great reactive support! This mb is the best i ever had ram profiles are amazing!

[Eldonko]

Yeah the memory profiles that the ROG team built work really well. Plus the sub zero profiles help too. You dont see that kind of thing on many (any) other boards.

Just need a Micron preset now. I think we will see a fair amount of Micron on 16GB kits.

[Viss]

Bios 0083 runs smooth Loaded the Hynix (tight) profile and only changed tRCD to 11.

Well the 83b bios is running great for memory and cpu: I'm going to say at this point I feel there are problems with USB interrupts and stability in general. I've been having problems with the board dropping the dish 622 with a Nextcom r5000hd recorder in it and before switching the bios to 83b I started having problems with the board dropping my g9 logitech mouse. Latest drivers from logitech and at this point I've tried basically all the usb 20 ports and now have moved to the spare usb30 ports since two of them are lost to the dvrs so that my boot sequence doesn't hang on 99 for 3:30 minutes. Pow just lost the lpouse again as I was moving it across a page to change websites --beep beep just lost it again typing this message, this is pretty ridiculous and I don't have all the ports full so why should Ibe having porblems if the bios is assigning the usb ports correctly? Anyone else having these problems and how many usb ports are you iusing for which devices? stephen

[LardArse]

we'll be workin on the usb to see whats goin on over there for you, you seem to have lots of usb devices hooked up, just a guess since your problems sound random and not always regular -> did you try plugging in a floppy power connector to the small white floppy power input connector just to see if your 5V is saggin over at the I/O?

The extra power connectors are plugged in both for PCIe and USB--thanks stephen

I've run into a bit of a strange problem. I'm currently running at 5Ghz (50 x100 bclk) @ 1.448v. It's prime stable and LinX stable for 30 passes....likely longer though I have not tried. I
m getting a BSOD booting into Windows on cold boot after the computer has been powered down, or even a warm boot within the first 10 minutes the system is turned on. After the system "warms up" it boots fine at the current settings and appears to be completely stable...prime, LinX, games, etc. Only when the system is "cold" I have this boot issue.

Specs are in the sig
BIOS 0803
VTT and VCCSA are on Auto
DIMMs at 1.65v per XMP for the Gskill 2400 Ripjaw Z
Setting RAM to 2133 CAS 11 doesn't help
CPU voltage is set +.90 (because I prefer to keep Intel speedstep working with voltage adjustment)

Ideas? It's odd because the current settings seem totally stable after the systems been on for 15 minutes.

[LardArse]

Try setting transmitter/receiver slew to normal manually.

[mdzcpa]

Let me give it a try and report back after a few cycles. thanks.

The USB drama is over--the problem worsened over the evening so I did more testing by removing all the USB components and then plugging individual items, turned out that the cable on a relatively new mouse was bad and that was the root of the problem. Thanks for the attention and help but testing on your end is unnecessary. I'm back to just complaining about your choice of chipset for the extra SATA 6gbs--I'm getting 350mbs on these ports when I was getting 860mbs on the Maximus series with the Marvel chip running in raid 0---if you guys made this choice for the LN2 overclockers that doesn't make any sense they don't tend to use peripherals so you down grading a chipset on a great board when workstation users DO use those peripherals doesn't make any sense, I'd happily pay another $10 or $20 for good performance on 4 SATA ports instead of this bad performance that leaves my anxious for another board that wouldn't have this problem.

Is there anyone using Quad-Fire with the Rampage IV? I've lost 2 hours trying to make 4X Lightning 6970 work on it. I get a computer reset/restart in every games or benchmarks. Tri-Fire is working fine in any combination, slots, and with any 3 cards. So the cards are fine, and the slots are fine. But Quad-Fire doesn't work.

Everything is at stock (CPU, RAM and GPUs), I have test my RAM and they are fine. I use 2 PSU for 2100 watts total, on 2 dedicated 20A circuits. Easy-plug 1 and 2 are plugged. I've test both PSUs in another system and they are working fine. Cards are watercooled and not overheating (cores are under 40 celsius and VRMs under 45 celsius).

Could it be that ATI, like Nvidia, were not ready for X79? I know Nvidia surround is not working with X79. Could it be that the latest ATI drivers where not ready for Quad with X79? I just need a confirmation that it's suppose to work, or not, and will continue/stop fighting with it.

Am I missing something in the BIOS?

will let you know tomorow, not with Lightnings yet, just regular 6970x4. For now maybe try stuff like HPET Disabled for now under BIOS PCH Config, and also manually setting under BIOS system Agent to Gen2/Gen2/Gen2 stead of Gen3

Ok, thank you. I'm at work now, but will try it later tonight.

I just tried different things today, without using MSI Afterburner.. Metro 2033 is playing fine at 1080p, but always hard resetting at 2560X1600. Also, Furmark is hard resetting at 2560X1600 and 1080p.

CPU, RAM and GPUs all at stock, no OC.

[LardArse]

sounds like a PSU load issue though, not saying 2 x psus arent anough but if you have set up the pcie connectors in a way that one rail is overburdened then the 12v droop maybe a cause. if you got some pics or explanation of the pcie connector set up in details (the psus should state which rail each connector comes from)
maybe a test such as underclocking the vgas and then running 2560x1600 or running 1080p WITH the gpus overclocked, to narrow down if power is an issue or not

[Levesque]

I'm using a Corsair AX1200 + AX850, so no rails on those. And each of those is plugged on 2 dedicated electrical circuits.

The 850 is powering 2X6970 + 32 GT 1850 fans + 4 pumps MCP655. So under 850w here. The 1200 is powering 2X 6970 + Rampage IV + 3930k + RAM + HDD. I don't think this is over 1200w...

The 3930k is at stock. Everything is at stock.

And thank you for your help. I really appreciate it.
