UnOfficial Asus Rampage II Extreme Thread

[zsamz_]

Strange thing this, and I wonder if you guys can help?

Upgraded my PSU to a Corsair Professional Series Gold AX 1200W PSU, the one it replaced was a Corsair TX750W, nothing else changed as regards my setup.

When turning PC on after leaving overnight, system seems to boot OK, but monitor seems to go into sleep mode?? A quick push of the reset button on front of PC and the system will boot normally with monitor OK. Dammed annoying to have to do this every cold boot.

I know the system must be booting OK in background as when it does start after reset, I get the option to 'start Windows normally' etc., which means it was probably booting OK first time, just I had nothing on the monitor.

If I shut PC down and start it and hour later, I don't get this problem, only when left overnight.

Upped BIOS from 1406 to 1504, no difference.

Got me stummped this one has

Many thx

thats exactly why i shy away from corsair psu
too many glitches

Hey thx!

Your magical wisdom has helped me no end....

(can't you afford one?)

CryptiK,zsamz thanks for the replys.
but I rolling back to evga.no problem with that mobo.only increasing vtt and vcore and 4.2 with HT stable.
with rIIe was only 4150.trying evrerything,changing bios and...no luck.
i gonna miss about LCD poster

Meh LCD poster is overrated, I don't use it for my board. Only time I used it was on my Rampage Extreme X48 for benching and in-windows adjustment to avoid CBB when subzero.

I grabbed an open box RIIE from Micro Center for stupid cheap. I'm currently using the latest BIOS 1914 but I'm wondering if there isn't a better one from Bloomfield as it seems like I need more VTT than usual with this board for 4000MHz uncore/DDR3-2000. It doesn't help that it droops quite a bit, 1.50v bios set gives about 1.44v on load DMM measured.

[EDIT] Browsing a few posts back, looks like 1504 would be best for Bloomfield Xeon, and high VTT for DDR3-2000 is normal for this board. [/EDIT]

rexII needs alot of qpi for 2k
and use bios 1504
its droops qpi

rexII runs best with bbse or good powerchips
i got 12gb stable 215x21 1713mhz 6-7-6-18

Hi Rampage users!

I got couple questions, Ive got this mobo for over a year but just since September I wanna overclock bit more

What is the best BIOS for R2E? Im using now 1801 (the newest one) for i7 920 D0
What QPI Voltage is required for 4.2GHz (now i put about 1.3v)
What about NB and SB voltages what are recommended voltages for 4.2GHz.
Perhaps I should increase PLL voltage?

Thanks for reply

[Shiranui Gen-An]

¡Ay, caramba! this thing needs VTT set high for 2000MHz DDR3! It was more like 1.50v real but still, I only needed 1.40v real on the EVGA Classy with the same chip. Oh well.

[KILLER_K]

@ Shiranui Gen-An, why is your cpu voltage at 2.570 and the other shows 1.323 volts?

[Shiranui Gen-An]

CPU-Z bug apparently. I obviously wasn't running 2.57v

[CryptiK]

Required 1.31 Vtt for me at DDR3-2000MHz CL8 HCI Memtest stable. I don't run this 24/7 though, was just testing seeing what things needed. Vtt requirements do seem higher on the REX2 from other peoples reports but I've never used my CPU on another board so I can't comment personally.

you one of the lucky ones with a real good imc
the qpi droop is bad on the rexII

[KILLER_K]

@ CryptiK how are you getting such high copy speeds on everest? I ran mine at 4.5ghz and yours is way above mine but less in other areas.

higher ulk frequency
he's @ 20x
memory n imc needs to be real good for that

Hey guys,

I'm having an issue with my R2E, and I remember seeing something about it somewhere quite some time ago. I am finishing a system rebuild, and when I went to power up, no boot. After several hours of troubleshooting, I've discovered the white slots are no longer working. I only had 3 sticks of ram, and didn't think to try some in white, some in blue slots, so not sure if that works. I boot fine with all 3 blue used, but no combo of white slots only worked. All settings are stock, with 19xx bios (can't remember exact #). CPUZ still says triple channel ram when in windows with all blue slots occupied. Is it a board issue, or cpu issue? Its the only 1366 board I have, so can't try cpu in another board.

No problem with the board, just the builder

You MUST use the blue slots first, then when full you can use the white ones, thats just the way all x58 boards work.

920/REII is dead and was working just prior to switching mobo's.

Had a working 980x in the REII before I started swapping boards, cases, cpu's.

Took the 980x and put it in a REIII which went into an Obsidian WCed rig.

Went to fire up the 920/REII and nothing. No beeps, no video, just the fans fire up. ROG display shows Welcome, then goes to the timer, nothing in between?

- Reset BIOS several times, via ROG reset, also pulled CMOS battery for a while.
- Hooked up different PSU, same thing.
- Reset CPU twice, checked and cleaned contacts on pcu and board.
- Tried different memory
- Tried different video card
- Removed board from case and tried everything again (shorting?)

All with the same results? No beeps from the CMOS has baffled?

Anyone experience this before and found a solution?
Anyone have anything else I can try ? This board was functioning fine with the 980x and the 920 before I moved it to another case?

Just to let you guys know turns out the board had died. Asus couldn't even get it going so they sent me a new one.
Strange how just moving a board can cause it to fail, although I think it was flaky from day one as I had to isolate the metal standoffs with electrical tape because according to Asus it was shorting? No tape needed on the replacement board.

Thanks, didn't realize it flat wouldn't work in the white. I'll try that tomorrow.

[DashTrash]

Ok, I feel pretty stupid. I tried it with 4 sticks, 3 blue and 1 white, and it worked fine. I found the manual, and sure enough, it states "Due to Intel CPU spec definition, the system will not boot if only one DIMM is installed in DIMM slot A2, B2, or C2." I vaguely remember reading this before, but forgot. Thanks for help, though.

[Johnmark]

No problem, sometimes its the small things that trip us up.

[theveteran]

For me with the bios 1504 the MAX BCLK STABLE 221X19

Thats one heavy oc,is that with HT on?
You prefer the 1504 bios to any other bios?

[Maxpayne]

Hey guys, ask how do I set the RAM, so I went to 2000MHz or more

I have Goodram 3x2 2000mhz 8-8-8-28

My OC is core i7 920 to 4.3ghz (205x21) ht on

[Solarfall]

been lil out of the ocing game for the past year, got the spark to start torturing gear again.. heres my poor 980x under watercooling, yeah i know the voltage is abit ehmmm crazy the super pi run is just for testing i know the score is not all that great.
this chip stops pretty much scaling well after 1.63v at least on these temps, it seems to needs some colder temps and cant wait to bolt on my cascade and try how this little devils likes -100c

[KILLER_K]

Well i hit 227 bclk on mine tonight. Not too bad for a air run though. Not sure why my cpu voltage isn't showing, perhaps a bug i guess.

[theveteran]

Hi there.

i need a little help with achieveing 4.4 ht on,i have achieved 4.3 fully stable with linx,occt,ibt and prime 95.

I notice some people on here have 4.4 with a similar setup to me,all my motherboard is watercooled.

Any help will be really appreciated
Here are my settings.....thanks.

your cpu pll is a bit high lower it to 1.8 raise your ioh to 1.2-1.26v and add more juice to cpu if needed
raise pcie-103-108
