UnOfficial Asus Rampage II Extreme Thread

[Ranger07]

So far the Corsair Dominator XMS3 1600MHz seems to be the common factor. Is there anyone using Corsair Dominator memory and NOT having cold boot issues?

Thats what I'm using and I'm still getting the cold boot issue.

[Nemon]

My 920 does 4 Ghz but i need 1.5 volt & 45 idle
so i settled for 3.8@ 1.35 volt 200x19 and 10C less with ht on
Im going to stay with this untill this is fixed( I hope)

my everyday OC

Ramguy, I have an hr05 and I could try it when my second loop components come in I change my NB cooler so I could use my x-fi titanium!!

Any luck yet?


When it comes to this coold boot issue, that's something I've experienced with my Asus P5N32-E Sli nForce680i motherboard, my Asus Striker Extreme motherboard, don't think I had it with my P5Q-Deluxe though?

Anyway, this seems to be a Asus issue and not a motherboard issue in my opinion and is a real pain in the arse!

If that coold boot issue will start to haunt me, I will just keep my Rampage II Extreme until the Foxconn BloodRage, DFI LanParty UT x58 or something arrives and get good reviews, and then I'll simply RMA it and replace it

I don't have cold boot issue but I'm using regular PC3-10666 memory and I don't run OCed all the time. I only did a few CPU Up Level OCs to a i965 to see how it runs and it ran okay although SuperPI freezes every single time when running the 32MB test. I guess either my memory or CPU sucks, so I put everything back to stock and just run it that way. No money to buy higher speed memory, so I will never know if mine has the cold boot issue or not.

Yeah I agree it's an Asus problem, I have the same problem with my x38 Maximus Extreme.Each time I have to power on the psu and then off again before it will boot.

This is putting me off getting this board for my move to i7.

[BringerOdeath]

Here you go ramguy, I had to improvise a bit!!

Heres my OC, got it stable @ 4.2 HT disabled 1.440 volts on cpu.

I know its too early to tell but 1.440 cpu volts should be pretty safe for a 24/7 ?

Nah, that's a crapshoot. I noticed that if Uncore is much greater than QPI or the memory speed gets very high I will lose channels, but not always, even by a long shot. And when it starts to happen, I reset the CMOS, re-enter my settings and I'm back to normal. Something else is causing this.

ATM, I am running 4.14GHz with 1800MHz DRAM (3600MHz Uncore, and 3960MHz QPI) with no problems...

Also, after cold boot not happening for a couple of days, I have had it happen twice in a row in the last two days (today included).

[theonlybabyface]

I am also having the cold boot issue when overclocked. Currently running my 920 @ 3800 mhz with 1.35 vcore. I will post all of my bios settings here shortly for others.

[skypx]

Ok, anyone having cold boot issues and NOT using a PCI based X-Fi sound card? I know guys, but please humor me. Thanks.

[Fitseries3]

im using just 3 gtx260's. i have all onboard stuff disabled.

i only get the cold boot issue if i leave the machine at a high memory OC when i shut it down for the night. im using gskill black PI 1600mhz 3x1gb


Question for everyone: how many of you have noticed that older 2x1/2x2gb kits OC better on x58?

[OcAddict]

Ok concerning the cold boot issue, i think i'm on to something! I've set my RAM timings manually. Especialy this one "DRAM Back-To-Back CAS# Delay", AUTO sets this value to "0" and i have set it to "18".
Since then i'm cold boot issue free, 3 days and counting Can you guys test this and confirm if this is working for you?

Interesting. I will try it now.

[theonlybabyface]

OK. I can confirm that setting is the one. However, setting the DRAM Back-to-Back CAS# Delay setting to 18 causes a huge hit in memory performance (cuts it in half according to Everest). I simple set it to the lowest possible manual setting of 4 (BIOS sets it to 0 in AUTO) and the cold boot issue is gone and a minor hit in memory performance which I can make up on other settings anyways.

Good job..maybe we should be working at ASUS???

[theonlybabyface]

PS - This also fixes the sleep issue I was having earlier. I can now come out of sleep mode without issue as well!

Good to hear that this is working for you to I didn't test it with Everest yet before i was sure that the issue was gone! But you did it for me, thx for that
ASUS, interested

Yes i noticed that to

well your answer is a crapshoot this is on my board i dont use the uncore and if i overclock my bus speed to 150mhz and leave my ram set to 1600mhz 1.65v my ram drops down to 4gb, when uping the voltage to 1.7 and higher it drops more down to 2gb, down the volts to 1.6 i get all my ram back, i have more testing to do tomorrow.

Just tried it, set the 1st information manually, with 4 and 18 as the back to back cas# delay, unfortunately it does not work. Still having the cold boot issue, thanks for trying though.

[ReVolut1on]

Just curious.. If asus ever release new revision of this motherboard, will you be able to RMA your older revision board for the new one?

Do you even understand what crapshoot means before you decide to run your mouth? Maybe I'll point you to a definition...

crapshoot - http://www.thefreedictionary.com/crapshoot

Next time bite your tongue please....nobody was insulting anyone.

Now that we got that out of the way, are you on an R2E or EVGA X58? Because EVGA has some serious issues with memory it would appear...and this is a R2E thread so quite likely EVGA experiences will not apply. Also, what do you mean by "you do not use Uncore"? You cannot "not use [it]". Uncore is part of the CPU and it stands for everything that is not CPU core (yay Intel engineering team, great name ), i.e., cache, IMC, etc., and it needs to run at minimum 2xDRAM speed.

Just curious.. If asus ever release new revision of this motherboard, will you be able to RMA your older revision board for the new one?

No. That would be an equivalent of a mass recall. That is not the point of an RMA. But it would be nice if that's how it worked.

I have not tried this yet, but this seems to point to a memory incompatibility issue. Can't say that R2E does not have this problem...also, I would say you need to test this out over a couple of days, or at least in my cause I would have to as cold boot problem does not happen all the time...

Maybe this board just needs a nice warm blanket and some tender hugs to run nicely

[ReVolut1on]

Hm... It kinda sucks that their customers will have to pay for their mistakes! Has Tony even guaranteed the new revision or are those just rumors. (btw ordered my gigabyte board hoping good results)

[FZ1]

I just got off the phone with Asus support where I laid out all of the problems seen so far with this board...the list follows...

1. Disappearing memory channels/memory detected incorrectly (e.g., only 2GB out of 6GB get detected at boot). Depending on settings, this can be triggered at will and is not normal. BIOS used does not affect or correct this.
2. Instability at 200MHz BCLK and/or 20x multiplier (but not above or below). Possibly there are more combinations that are unstable with 20x multiplier.
3. IOH voltage is stuck (i.e., cannot be changed and/or there is a huge discrepancy between the set voltage and actual voltage...I'm talking 0.08V or higher). In one example I set the IOH voltage to 1.32V and the actual voltage read only 1.24V, same as when the voltage was just set to 1.24V. I don't think 0.09V is considered acceptable discrepancy. Furthermore, no matter how high I go with the settings (I tried 1.5V) I only got 1.28V max on the board using a DMM. That's a whopping 0.22V difference!
4. Random (cold-boot) no power up after shutdown. Appears to happen for no reason, PSU was ruled out, DRAM was ruled out, BIOS was ruled out, graphics were ruled out, even CPU was ruled out. Requires typically a CMOS reset, complete power cycle, or a wait time before trying to boot after initial failure.
5. Motherboard not rebooting correctly after a BIOS update and requiring CMOS reset to be hit every single time (this is not normal behavior).
6. SLI Configurations not working on all of the boards. I did not try this on my board.
7. ROG light not blinking when the computer is off as it is supposed to but instead staying steady. This appears to have something to do with the cold boot as they seem to happen in conjunction, but I am not 100% sure.
8. No ability to delete O.C. Profiles from BIOS without reflashing the BIOS.

Anyway, my board is going for an RMA as soon as Asus verifies advanced RMA stock for shipping to Canada. Hopefully, the new board will have no problems. If Asus forums are any guideline I am in for some good times, at least in terms of the memory issues. There have been a couple of individuals there that had this issue, RMAed the board, and the replacement worked flawlessly. I do hope!

The OP should add this to the first post in the thread and update as needed. More people will see it that way (people are lazy and won't read the thread) and it may result in getting more info and findings to help isolate the issues.
