short testing on air

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?

when u press "start" button, wait about 10-15sec, if no picture displays, press "restart" button and wait 10-15sec, and if no picture dispalys restart so about 4-5 times and it should turn on i had the same problem

[GoNz0]

i had it, got as far as removing all the wc blocks and was about to pack it for rma when i pulled the battery, reset cmos a few times without power, then with power. put the battery back and it worked.

if i didnt have the CPU power cable in it would turn on and go straight to timer with no functions not even off. (checking the obvious)

[Johnmark]

Yea I did all the restarting, resetting BIOS a gazillion times, removing the battery, etc. still no go.
When I first bought this board had trouble with it and put electrical tape on all the stand offs, in order to get it working. But at least I had beeps from the board then. Now nothing, just the fans spin up

Hi guys i need help now i have problem with my Rampage II Extreme mobo and G.Skill Trident 6GB 2000Mhz i cant get my memory working stable on 2000Mhz -Windows 7 x64
i had the same problem with my old memory 6GB OCZ Blade 2000Mhz random BSOD and lockups they both run very stable on 1600Mhz but not on 2000Mhz
i didnt have this problem the first few months when i first get this mobo
i've tried every bios version (from 1406 to 1913) and settings that i can think of
my friend tells me that in asus forum have fix for this but i cant find it if anyone can help me i will really appreciate it

Why not back down to 4Ghz and 4000 uncore and give that a shot. What are your QPI volts at ? What is B2B at ?

I tried this i try everything i can think of QPI is 1.45 higher voltage didnt help
and what is B2B ?

takes more than 1.45v qpi to run 2k on the rexII
your better off runnin 1600-1800 cas6

my old tridents were good for 1800 6-8-7-24 and only need 1.36v vtt qpi
your blades should be good for 1700 6-6-6-20

and best bios for 920 is 1504

[dpajur]

Whats the max safe qpi for a watercooled CPU and standard (passive) cooled RIIE?

I'm running 1.45v qpi and can't get higher than 4ghz on it. Setting it any lower causes instability even at 4ghz.

[GoNz0]

i would not run over that, and do not forget 4ghz may be the limit for that chip just like mine.

[zsamz_]

bump ioh voltage
qpi voltage has more to do with memory than the cpu

[GanGstaOne]

yep i fix my memory problem it was the QPI voltage the mobo sets very low voltage this was the problem

[rurik]

sorry,but reading thread,not understund,what max safe voltage for 24/7 qpi/dram?
1,45 is ok?

[GanGstaOne]

yep even 1.65 is ok you can search in google for settings for your memory

[CryptiK]

I wouldn't call 1.65 vQPI safe for 24/7. There really is no 'safe' voltage above the absolute max intel spec, just voltages that people have used for relative time periods and had no failures or obvious degradation. 1.45 is around the top end that that range, 1.55 - 1.65 has been used but usually for shorter benching sessions.

your spot on Cryptic

i would expect degradation @ 1.55+ for long term
for 24/7 even i wont go 1.45+

[rurik]

Cryptic,szamz.
thanks,1.45 i think is ok.my ripjaws need 1.45 qpi at 1950mhz,but 2000 i cant manage.
i think,its motherboard problem.
i rise up to 1.50v qpi,but cant stable this sticks.
and second,i also have evga x58 sli3 mobo,with this i stable at 4.2 with HT on and memo 1600 without problem.with rampage i only have 4150 with HTon and memo 1550 or 19xx(dont remember).
i trying everything,but linx crashes more,than 4150.it not chip,i know,its mobo.my previus mobo was RE 775,it was great mobo,but this one...i dont know.
with evga was too easy overclock my chip,only cpu voltage and qpi voltage,other was on auto.
with rIIe it was harderer,same riseing cpu and qpi voltage,but chip not stable...
one thing,with evga was one gpu hd 5850,with rampage i trying sli with two gtx460.may be this is a problem?
thanks for the replys,my brain is stuck...

[toytamer]

what is the last bios beta

[zsamz_]

raise ioh voltages a tad for 2 cards
the rexII is alot better than a 3xsli the e760 is better than both

Cryptic,szamz.

I dont know if 2 cards makes much difference really, I was using 2 x GTX285's for quite awhile and didnt have to change anything compared to one of them or the GTX295 I use now. Always same vIOH (1.13v BIOS giving 1.11v real) and stock PCI-E voltage, only things I ever increased were Vtt and Vcore and I had 4500 MHz stable.

it all depends how good ioh is

my first rexII handlin 5970+5870 on stock ioh voltage @ 4.5ghz

my second needed 1.14 on ioh
my p6t7 ws supercomputer needs 1.2v with 2 285s
my rexIII needed 1.27v for 5970+5870

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

[rurik]

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

for your xeon best bios would be the 1504 on the rexII
you just need to find the right setting

i know for a fact that the e760 will make your 980x happy
