UnOfficial Asus Rampage II Extreme Thread

[BringerOdeath]

Cold boot problem here as well. Seems related to power supply used. My BFG ES-800 is worst, PCP&C 750 silencer not as bad, and the Corsair HX620 almost no problem at all. The problem occurs at stock speed also. Will be RMAing the board.

Thermaltake Toughpower Modular 1200watt...

i havent had any problems with my corsair 1000hx psu...all good here...

[sonofander]

Bought on relase day and had to pay tax
That's why it was so much
Oh well, the upside to the local purchase was the 30 day return policy which I ended up using

Anyway, it's funny how context is so important. I was really dissapointed in a 4.3 clock on the 965 but I'm thrilled with the same clock on the 920.

[Fitseries3]

I had 2 9800gx2's with one card in the bottom slot at 8x and one card in the top 16x slot and it had enough bandwith! Then i moved the lower card into the middle blue slot so I could have 16x and 16x and the scores were identical. With pci-e 2.0, I don't think it makes a difference!

i get almost the same scores with 2 gtx260s as when i run 3 cause the bandwidth is choaked at 8x on 2 cards. i had this same problem on p45 and x48. i have had one board ever to have 3 full 16x slots and MAN did it fly. FPS where way higher than at 16 8 8 .

i will have proof when i get the P6T6 Revolution.

Did you try to OC it hard?

I see where your coming from though- Im looking to buy a new CPU and the EE is on my list, but after seeing most ppls clocks- There feeling shy !

It seems no one cares about trashing the 920 CPU.

Ive seen some ppl run there 965 at 4.5 with pretty low heat.

My buddy OC'd his to 4.4 by simply rasing the multi at stock, nothing else.

Kept everything else the same!

I see alot of ppl going 4.2 and over on the 920 but after a week or so they have to change there OC because it wasnt fully stable.

you might wanna do a 24 hour prime run and see how it fares.

[sonofander]

I pushed 1.6v through my 965 trying to get it to prime at 4.4 with no success
For me the trade off is a no brainer at that point. Even if I had to settle for 4.0 (which it seems every 920 can do) there's no way that 300mhz is worth $700 to me. I was willing to pony up the extra dough for some extreme clocking, but siceit seems that the 965s aren't really better chips, I'll put the money elsewhere.

TBH I just love the tri-sli on an intel chipset, CPU clocks are secondary at this point

It's the usual, "luck of the draw" with cpus....."Cpus are like a box of chocolates...,you never know what your gonna get!"

How do the dual 4870x2's run? Whats the performance on these?

[ReVolut1on]

Hello guys! Do you think i would hit 4ghz 24/7 with:

Asus r2e

Corsair dominator 1600 3x2gb cl8

i7 920

Two xfx gtx 280 sli

etc. etc.

What are the odds?

[BringerOdeath]

Well, I you do 4ghz, no problem on 920. More than that is hit or miss.....

[ReVolut1on]

Ok thanks. Btw is your clock in the sig prime stable?

Edit: i will be using the noctua 1366 push pull cooler

[BringerOdeath]

Yes, but I think I will have 4.134 stable here also.....Working on it.

I Believe this cooler is the best aircooler....PERIOD!

or if its a bit too expensive, this is the next best!

Wow! Good to hear youre getting so good results with it. Keep pushing that beast!
This indeed sounds very promising.
For the cooler, yes, i know true is da best but i don't have the 1366 version avaiable here so i gotta take the second best.

[BringerOdeath]

That place cab ship internationally you know.....hehehe I understand not being able to get something, I still can't get a lga 1366 hold down for my fuzion v2 block......I made something up!

Was it the 790i Ultra Fitseries? I had that one before this, but pci-e soundcards are incompatible with that board and I can't stand onboard sound....

[OcAddict]

i havent had any problems with my corsair 1000hx psu...all good here...

Same PSU here and i have the cold boot issue, can't be the PSU then

Well, I you do 4ghz, no problem on 920. More than that is hit or miss.....

Whatever i do i just can't get 4.0GHz stable on my 920

Made something up for my FuZion V1 aswell

[BringerOdeath]

Wow, cool idea!! What I had to do is flip the metal hold down for 775(pro mount) ange some screws a little bit and put huge rubber washers on the back to keep the bolts from damaging the board. I used springs from a tuniq tower clamp it down with some nuts....It doesnt look too bad and works great!!

vnice
i had to settle with getting a new gtz...cant go wrong with that mounting system....good job

[dejanh]

while running p95 temps rise to 56c after about 30seconds then hardlock.

the thing i dont understand is the first week i had this setup this cpu ran 4.3ghz easily. i even got a screenshot at 4.5ghz.

Um, sounds like your CPU is dying my friend...maybe a little too much voltage?

If you run the volts too high it will suffer degradation and then even at the same volts you will not be able to get the same clocks. Over time, this will get worse up until the point where you need like 1.5V to run stock speeds and the chip dies.

On the note of the cold-boot issue...seems to be a lot of people that are having this problem. It is not the PSU for sure. Two people with the same PSU may not get the same problem. Sounds like faulty boards to me...

Did anyone RMA the board and got a working replacement?

Also, I wonder if there is some kind of fault on the boards could that be affecting our OC ability as well? What are your OCs like for people that have the cold-boot problems?

[marleyman]

To the people discussing heat issues, I have found that not only is the i7 965 a very stable overclocker, but at 3.8 I can run it 24/7 and it will not exceed 30c according to Everest, the same temp as my old QX6850. I am using a Coolit Elite thermelectric, chilled coolant system and it has been extremely effective; I do not even have the coolant temperature dialed down all the way. I am waiting on Danger Den blocks to hook my HD4870 X2s up to another Coolit. For sure in my years of working with computers I have not run across a more impressive CPU from a technology standpoint.

I also have a problem with my Rampage II which I wonder if anyone else has ever experienced. It will only recognize a DVD or CD in my drive if the DVD is in the drive when the system boots up. Otherwise if you later put a different DVD or CD in nothing happens and the system locks if you try to open the DVD. The DVD is currently the sole unit (I disconnected the other), I traded out the unit, it is set to parent, it is getting power, I have flashed the BIOS, since it is a new build I reinstalled Vista Ultimate and finally I gave in and am waiting for a SATA internal DVD/CD to arrive. However, if anyone knows of anything in particular with this motherboard which could be causing the problem I would really appreciate the info for while the problem is not hugh it is one of those little things that drive you crazy chasing down.

Thanks

dont take me wrong... i can boot at lower voltages but its no where near stable enough to do anything other than boot the machine.

stock runs at 1.1v with this chip still. even when i ran it on my TEC it needed a fair about of voltage. i can still get 4.4ghz to boot but getting to the desktop is like a 1 in 100 chance.

i have the cold boot problem as well.

at first it wont do anything other than power up the fans and lights. i hit the reset button and then it will hang on DET_DRAM for a min or so then i hit reset again and it powers right up. very odd yes but this isnt the first board this has happened with, 775's included.

Yeah, see, I have been on the AMD boat for the last 12 years so I have no idea how anything worked in the Intel world. Core i7 is my first Intel build since 1996. The cold boot is sure annoying though. I am just curious to see if there is some parallel that can be drawn between the cold boot and the crappy OC requiring a ton of voltage on certain boards. After all, cold boot is indicative of a power problem of some sort, and having to provide a lot of power to make OC stable and/or not being able to stabilize it at all could also be indicative of a power problem.

[skypx]

I had a long discussion with Asus tech support today about the cold boot issue. Unfortunately they are unaware of the problem, so I guess it's up to us to find what's causing the problem. My computer specs are in the sig below and if we could work together to get this issues solved we may be able to present our findings to Asus for a fix. Thanks.

Any idea if the "Thermalright HR-05 SLI / IFX" will fit on this board?
I see it's easy to swap of that annoying northbridge heat-pipe that is blocking for my Asus Xonar audio card!

Any idea if I can swap it with a HR-05 SLI / IFX? That would make things both cooler and making my Xonar HDAV1.3 Deluxe fit perfectly!
