thanks LardArse for the advice will get to it right away , board seems stable as hell the with all memory secondary timing tight as can be . .
very strong in memory dept
I need more work getting stable at 2000c8 with the hypers, so I decided to go up on the cpu multi.
4.7 seems to be running ok, a short blend run.

Ordered my Rampage IV Extreme :)
Im using default blend at the moment, have 3400mb of free memory available out of 8gb. Im not going for 24/7 stability on this oc, but this is IMO the best way to learn a new setup. Then off to benching.
got my R4E up and running
just getting everything reloaded now

had it lose it's boot drive a (two ssd raid) till i unplug a usb memory card reader with a compact flash card in it then it booted fine :shrug:
i'm on 0076b bios
Thats a smoking setup, love that nicotine setup.
Too bad the board does not match but just need to wait after the next 100packs it will blend just fine...
Nice build bill_d :up:
Went up 100mhz, set memory to custom to stress more.

Ok, so updated( I think) the BIOS to 0802 using the EZ Flash utility. It all appeared to go well. The bios was updated and the system restarted a couple of times. Then I get to the Amibios screen and I can't get beyond it. It reads the bios as 0802 but tells me at the bottom to enter set up to recover bios setting. It says to press F1 to enter setup, but F1 has no effect. Hopefully I'm missing the obvious here?
Forgot to add, I now have the P9X79 Deluxe with the 3930K and a 32gb Gskill kit.
Can someone help me out with a suggestion?
Thanks!
What's with the 3:30 plus minutes sitting on a code of 99 during post? The board and processor seemed fine a couple of days on bios 0604--then I moved up to 075b and then 076b. With a few crashes now the machine posts holding at code 99 forabout 3 and a half minutes and then completes normally--is the board gone bad or the processor? why such a long time and why such an extended post process and time? Thanks for any help
Any ideas how much a 3960x 5Ghz with 1.41v would worth ?

Thanks a lot! I am trying the BIOS Flashback. Is there any idea how long it takes? The Flashback button has been illuminated for 10 minutes or so. Will that light turn off when it is done?
I was looking for a 'BIOS update light' near the bios chip like on the ROG boards, but I didn't see one.
Thanks for the help.

[Update]This the screen I get stuck on. It shows the updated bios, but will not move beyond this screen. I have cleared cmos several times, to no avail. I know the keyboard works because I can restart from here with a ctrl/alt/dlt.
USB BIOS flashback has not worked, The light will come on, but will n ever turn off(up to an hour).
Did I brick the board?
If you can still to the screen you show above, sse only one memory module and see if you can make it into UEFI. BIOS flashback should only take a few minutes so something is amiss.
-Raja
Thanks for the tips Raja. There is no change with one dimm populated other than the screen I showed above does recognize 4 gb now. I really do appreciate the help.
It is strange, because it's not as if the keyboard is not working because I can reboot with it on that screen, but pushing F1 does nothing.
Any other suggestions?
Roger. Will do, thanks for the effort.
A g19 keyboard and mouse from logitech, a dell 3007hpc monitor with ports/slots (in the slot a lexar 4gb card, in the ports a headset charger without headset attached so it would come up as nothing and a microsoft sensor for a gamepad), 2 r5000hd video dvrs, a HTC phone, an ipod jack but without a device attached to boot, a canon printer. I suspect it is the r5000 dvrs that are causing the problem on an Asus Maximus 4 extreme and extreme Z that I previously used after I would hook up the dvrs the motherboard would show "no keyboard error' on next boot and I would have to attach an old fashion ps2 plug keyboard in to be able to make selections before post completes or after post to select different operating systems to run--steve
Unplug the USB cable to the monitor and see if the issue persists.
-Raja
Raja,
New UEFI for R4E 0077B link.....thanks.
On the 3:30 post sitting at code 99---it is the r5000hd dvrs that are causing the problem with being recognized by your bios. If I unplug the 2 dvrs then the machine boots in a normal time frame without hanging at a particualr code. This makes sense because typically after a post and boot into windows I get a 'usb device not recognized' erro message and then have to unplug the 2 dvrs and plug them back in to clear the problem. This is running through your bios because I had similar recognition problems with the m4e and m4eZ boards where once I put the dvrs in the system then my c19 keyboard wouldn't get recognized in boot. I'm seeing that happening intermittantly with this board because some of the boots I'll go to hit enter to go to an operating system instead of waiting for the 'time out' and the keyboard won't work. This has been a haunting problem with Asus noards and bios sense I came back to Asus 2 years ago--the problem doesn't exist with Gigabyte or MSI boards so it has something to do with your process for polling the USB connections and how you are handling it---how about working on a fix I don't want to return the board and go to another x79 board from a competitor?
I moved the 2 dvrs to usb 30 ports 2 and 4 and the hold on boot is down to around 20-25 seconds now instead of 3:30 minutes. It still causes some hiccups in the system because i can be working on the desktop; processing files and checking the internet and suddenly the mouse pointer will freeze up-then i get the beep from a usb unplug/plug and then the pointer will free up and continue working. Last time I tried to talk to Asus support about these issues they said that 'they don't test other people equipment for compatibility with asus motherboards, and that they designed things properly according to specs so it would be the fault of someone else's equipment anyway' nice attitude a few years ago. The dvr attachment is from Nextcom a r5000hd and the dvr that doesn't behave well is a dish network 622 a dish network 211 in the system never seems to drop. As i said in the earlier post other usb plugs are Dell 3007,ipod,htc android phone,canon prin,g19 keyboard and g9 mouse, occasionally a blackberry or a portable usb harddrive; nothing of consequence to the problem, common hardware--thanks for your input and help, steve

@Raja,
In all your 3930k/3960X MB testing a few days ago, what power supply(s) where you using, please don't say some $400 mini-megawatt PS. I now know now why my Sabertooth x79+3930k won't test and my Rampage III did.
My 4 pin + 8 pin EPS are on one 36A rail, 12V2 is for all external IO devices (drives and things), 12v3 is for 24pin MB, and one Internal PCIe 8 pin, 1 external PCIe 6pin. 12v4 is another PCIE Internal 8 pin and modular external 6 pin.
so my powering off underload is due to OCP on the PS.
I can run at 4.8Ghz @ 1.45, and power my board/cpu and GT 470 in LightRoom 3.5 developing/processing photos, all cores are avg. 70+% utilized.
My 990x overclocked just fine on this power supply becase the board pulled more A from 12v1 rail and not from the 24 pin.

Hi Raja,
I just got my deluxe, but it stop at post code 65/b5. Is it a faulty motherboard ? I have re-seat the CPU several times and system no post & the post code remain the same. I also clear the cmos as well but no luck :-(
b5 Intel Core i7 MRC Code - CPU - check above <---- the possiblitiy of faulty Intel 3960x is rare
65 Initialize PS/2 Mouse <----- I am using MS USB wireless mouse & keyboard
Edit: found the post code decoder but seems the new x79 deluxe have issue
Unplug any other USB devices, also try to boot without keyboard or mouse and see if it still halts. Lastly, use only on DRAM module and see if it makes it further than those codes.
Might be worth listing all your parts also.

A new tool from the ROG Team. Allows you to set overclock thresholds and voltage within the OS for your CPUs. Handy if you're limited by cooling but want to take advantage of higher core speeds during lighter loading. Give it a try!!!!
Enjoy :)
-Raja
Please start posting ALL your voltages. Seeing just VCORE means nothing from CPUZ, makes it extreamly difficult attempting to reproduce other same cpu results, if you can't see the rest.
Raja can you give me the secondary timings you set and the vtt and vccsa voltage you use please.
No need for stress :)
VCCSA 1.05V. VDIMM 1.68V.
VCCSA you guys will have to tune yorselves as it is CPU dependant
Timing set will be added to UEFI in a Hynix profile so you guys don't have to do anything but hope you got a CPU that has a strong enough memory controller and good enough DIMMs. You will also need to ensure you can put some time into finding the required VCCSA. In addition I may even post a guide on ROG forums for people who are struggling.

I wasn't really directing the request towards you, but to all that drop their 'success' stories.
But one thing to note for the AI Suite II developers, they need to wrap the application with a window. I went to take an "application" screen shot, and only got the header. How they are drawing it I don'tknow, but "alt-prnt-scrn" didn't capture the whole thing.
I know drivers/kernel not Win32 API's so I don't know what they need to do at the application window to allow it.
I do have a list of UEFI UI suggestions I need to type up though.. :D

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

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

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.

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

You cna just load the Hynix profile in 83B then Pinto. Does all the stuff for you, then experiment from there :)
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!
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.
Bios 0083 runs smooth :up: Loaded the Hynix (tight) profile and only changed tRCD to 11.

http://www.mediafire.com/file/gkiihd...ASUS-0083b.rar
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
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?
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.
Try setting transmitter/receiver slew to normal manually.
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?
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.
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
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. :)
Unfortunately this did not work. I've lowered my clock all the way down to 4.5 and I'm still getting the occassional no boot situation. Sometimes is BSODs at the Windows load screen, and now an occassional Overclock Has Failed message. But after I reboot at the same exact settings, it boots fine and can LinX, Prime, and loop 3Mark for hours.
I've tried raising and lowering Vcore without effect. I'm using XMP profile on my Gskill 2400 Ripjaw Z which seems to handle the times and voltages (including VCCSA).
Why it won't boot at settings that are otherwise very stable is tough to sort.
^ I have the same thing happen on bios 803. Doesn't seem to happen with previous bios versions so Im back to 079.
You can try what OC Nub suggests and / or check your pm for some suggestions on trying to pinpoint the issue.
Come to think of it, this may have started when I did flash to 0803. I don't remember the issue happening the first few days I was up and running. That's why the sudden boot issues kind of surprised me.
I will flash back to 079 and check my PMs as well. I very much appreciate your help.
yes that is 0083, just a different name, same bios. Let me know if that is fine like 079
I had the same issue today with this 0083 bios, which is why I went back to 0079. Tried raising vcore but still no boot. To be fair, I did not do any stability testing with this bios, I just loaded the same voltage settings that had worked great with 076 and 079. It may have just need a few voltage adjustments, but I liked 079 so it was easier to just flash back.
Flashing to 079b didn't cure the issue. I made the suggested changes via your PM. If these work I will peel them back one at a time until I find the trigger setting. The no boot problem happens every 4 or 5 boots....it's not consistent. I can LinX, prime, 3dmark and play BF3 for hours at my current settings.
I can replicate reboots during idle with high VCCSA + low vcore, while they run fine at prime 95. please set 1.20v VCCSA as well when trying
Forgot to add this:
Keep VCore higher than VCCSA for stability
Try to NOT have VCCSA less than VCore by MORE than 300mv for stability

Maybe a Lightning issue?
Uploaded with ImageShack.us
I think I have it sorted!
I lowered the VCCSA as suggested but the problem persisted...and seemed to worsen a little....BSODs 2 times in a row when booting when I usually would only get the one. So I went through the VTT and VCCSA settings at automatic and took note of all the preset voltages at the various ram speeds (1600, 1833, 2133, 2400). Although I was downclocking the ram from spec to 2133 and to 1833 (from 2400) the XMP setting was auto adjusting the VTT and VCCSA down pretty dramatically. I just went in and set the VTT and VCCSA voltages manually to be one step higher. In other words I set the VCCSA and VTT for the auto 2400 settings with the memory running at 2133. Boot problem gone.
It would seem so basic to have tried these voltage increases earlier, but the system was so stable under stress tests with less votlage I just didn't consider needing more voltage for a boot issue.
I didn't want to over volt more than I needed, so I brought the voltages down a little with some testing. I ended up with VCCSA and VTT of 1.3v for running the ram at 2133 and the CPU anywhere between 4.7 and 5ghz. Those voltages are somewhere between the 2133 (1.25v) and 2400 (1.35v) auto presets. I'd prefer to run those voltages lower as I know I am bench stable at 1.25v with anything I can throw at it. Even the 1.2v you suggested is LinX, Prime, and 3D stable. I'm not sure if there is something else I should be adjusting instead of these voltages in order to resolve the boot issue, but for now I'm rock solid it seems. I assume under good water cooling 1.44v Vcore and 1.3v VTT and VCCSA will be fine long term. In the meantime i will tinker with other settings over the next few days and see if i can resolve the boot issue another way and lower the VCCSA and VTT voltages.
I appreciate your help in this. I'm pretty happy with a 24/7 5Ghz SB-E machine. In fact, with the boot issue under control, there may be a little more under the hood still.
Forgot to add this:
Keep VCore higher than VCCSA for stability
Try to NOT have VCCSA less than VCore by MORE than 300mv for stability
Mdzcpa what VCCSA and VTT sorted yor issue???
Thanks
Add me to whatever list of people with 4 card problems. My gtx 580 came back yesterday and I added it into my setup of gtx580, gtx 560ti (physics) and areca raid card. Machine went through part of post and turned off. It would not restart, i pulled everything down to a video card and 1 stick of ram and all i got for several hours was a series of hangs on 14,19,AF,61,65 so it seems like the cpu is gone. While you're thinking PSU I have two a PC power of 910 running hard drives and a coolermaster 1250 running the board,cpu and video cards--can't see any problem there that setup was running a sr2 with two 5680 and 24mgs of ram with 3 video cards--steve
1.3v for both VCCSA and VTT cured the issue. This works when the CPU is in the 4.7-5.0Ghz range, running the memory at 2133. Lowering the memory speed or the CPU overclock allows for VCCSA and VTT to be lower.
At first I thought my IMC was just crappy on this 3960X and I simply needed the higher VCCSA and VTT to get the memory clocked to 2133 when the chip was overclocked over 4.5Ghz. But knowing that I can run LinX, Prime, and 3D for hours at 1.25v VCCSA and VTT once I acheive a successful boot tells me there might be some other settings I'm missing.
Mimic my problems. With 4 cards, my first Rampage wouldn't post anymore just like you, with a solid red CPU Q-LED, no matter what I did. Had to RMA the mobo. Thaught the 3930k was dead...
Couldn't post anymore, just like you, like the CPU was gone...
But that CPU is working fine on the second Rampage...
UEFI 0901 for the R4E.
1. Improve high frequency DRAM compatibility.
2. Add more options to Latency Boundary item.
3. Enable UEFI driver support for add on cards.
