UnOfficial Asus Rampage II Extreme Thread

[dejanh]

Updated my contest thread. Check it out here http://www.xtremesystems.org/forums/...d.php?t=220984. Managed to get 0.02MHz higher BCLK for a grand total of 220.82MHz

Don't be shy to reply

Greetings all, it has been a while since I have been here.
I just fired up a new build using a Rampage II Extreme. I will be reading all through this thred over the next day.
In addition to the R-II I have an i7 920, 6 Gb Corsair Dominator GT, a GTX 285 and a pair of V-Raptors in RAID-0 powered by a Corsair HX100W.
It booted fine on the first popwer up and I have now flashed to BIOS 1104.
My initial CPU operating temp is 43 C.
Much to learn but it looks like this is the place.

ah finally somebody to compare

can u run in xmp profile for the i7 920 for the gt's??
just see whether it can pass memtest86+

Man, I want those sticks :p I can't get them anywhere though, nobody stocks them here. Not planning to order from US as it costs way to much. I would pay $100 in duty alone if not more.

I'm guessing though you had trouble with them because your board would not do high Uncore properly. I doubt I'd have trouble with them since I can do Uncore up to 4.4GHz comfortably so far in triple channel though I've said that before about this board

hi does the Coolermaster Real Power 1000w Modular Power Supply work with this mobo thx for your time

I have this configuration and it works fine.

Yes it does.

Yes it does.

wicked thanx for the reply.

Hi

I've a problem, tonight i tried Galaxy 1000 - R2E - Corsair 1600C8 - 4870 512.

On boot VGA fan @ 100% and 3 red led on.

I tried with 2 4870, 8600gt and single ram on 2-4-6 slot.

The LCD poster just says welcome and then begins counting.

Incompatibility with the Galaxy?

Any idea?

Thx

Hi, which the best Bios for Rampage II Extreme x58 ????

YES I had the same problem! DROVE ME NUTZ! no matter what i tried couldent get it to fire up... went to Best buy and bought (and later returned) an antec 550w and it fired up immediatly. Just ordered the Corsair HX 1000 Which seems to be popular and works with the R2E.

I use 1104, haven't tried the beta one. I'm hoping Asus will release another soon?!

You can look at the first page for links.

which is the limit of overclock of i7 920 batch 3835Axxx?

What are slots 2-4-6? Are you using your memory in A1, B1, and C1 (blue slots)?

Alternatively, it could be your power supply. Did you plug in the 8-pin 12V power cable into the motherboard header and are you using the correct cable since some people have unknowingly forced their 8-pin PCIE connector into the motherboard?

If you have done all of this then maybe borrow one from a friend and try it would before buying a new one. The board seems to be finicky with the PSUs it likes. It's definitely an annoyance.

which is the limit of overclock of i7 920 batch 3835Axxx?

I had that batch number for the i7 940. The chip ran fairly cool but it did not overclock well relative to other i7s. I managed to get 4.2GHz but voltages needed to be around 1.45V. One thing I can say for sure is that the IMC on my chip was sub-par.

[etoo]

which the limit of voltage for CPU Voltage/QPI Voltage and CPU PLL 24/7 ???

[dejanh]

which the limit of voltage for CPU Voltage/QPI Voltage and CPU PLL 24/7 ???

I would not touch CPU PLL voltage. It will not affect your OC but it can kill your chip. The Vcore in my opinion should be kept below 1.45V for 24/7 and QPI if you want to be absolutely safe at 1.35V.

wansnt the uncore
i can run the rams 2000 CL8 but not CL7

for the uncore bro.. post a 1000% memtest hci.

[etoo]

I do not know what he happens here, that I obtain to stabilize with 21 x 192 1.40v, but in 20 x 200 I do not obtain to stabilize. What it can be this?

[headala]

Will it do 18 or 19 x 200? Figure out your max bclk with low multi first and then up the multi.

Well, I did not post a screenshot but I did do that test. I did not arbitrarily declare it stable I tested Uncore up to 4211MHz using Memtest86+ 2.11 and Memtest HCI for a few hours. It went fine. Maybe if I redo the test on higher Uncore (4.3GHz+) I will post the screens then. I was definitely stable.

In terms of the memory, I do remember now what you told me in a PM. My bad. I remember that the board would run them but not in CL7. That still baffles me. But we all know that this board is far from perfect

[BLHealthy4life]

Now......

I've been sitting at 3.8GHz with HT on for a few weeks, 1.42 vcore and 1.65 vdimm, all else 'auto' and everything OK.

Decided to turn HT off today, as its a 'heat' hog, and not much benefit, if any, anyway.

Upped BCLK to 211 @ 19 Multi (4005GHz) and tested with same voltages as above, and all passed LinX etc no problems. Decided to reduce vcore a little, so took it down to 1.40v, and all passed no problems...BUT!

2Gb RAM disappeared just like that, 4Gb instead of 6Gb? BIOS and OS.

Dropped vdimm to 1.64v, and presto......I have my 6Gb back?, not tested for stability as yet.

Any thoughts guys?

Hi.

Yeah, I'm sort of experiencing the samething....

It seems that if I go over a certain speed with 6GB, mainly 1900, 2GB just dissapear...

anyone else experiencing this where 2GB RAM just dissapear with certain settings?

Yup, this is a known behavior. I am not sure if it can be attributed to the board or the IMC or a bit of both but either way it is there...

Hi.

Thanks for the reply!

So, if I were to go to 3GB, then it may not happen.

The board and/or the IMC cannot handle 6GB at 1900Mhz+ it seems....

It can. It is your timings. You would have seen the PM I sent

no bro asked cause wondering what ratio u used for the ioh/ich voltage.
