***Asus Rampage III Extreme Owners Thread***

[fl0w3n]

Here's a little test I did last night, BCLK at 230MHz, No Slow Mode. Maybe I could tighten some latencies on RAM, but 2300MHz is good anyway, and it was all about 230 BCLK.

I have 240+ w/o SLOW mode

Did you guys just get lucky with good quality IOH's or are you using some cooling other than air to reach higher than 226 BCLK with out slow mode?

Which BIOS are you guys using as well?
Donmarkoni shows 0011, not sure what that is



I'm having some issues as of last night, I got a weird start up issue that took me a while to trouble shoot and finally nothing short of moving the jumper pin to CLR CMOS AND removing the battery would get the board to turn on...

and this is using settings I've been stable with for a long time.

1005 bios.

CPU cooling by SS (-40c), IOH cooling is standart + 80mm Fan, I use 1005 bios

Just Air cooling with 80mm fan on IOH chip.
My favorite BIOS is 9124.

My 980X has BCLK 250MHz wall.
So maybe my REX3 can pass over BCLK 250MHz w/o slow mode with good chip.

BCLK limit depend on CPU & IOH quality.
So you had better to check other mobo, the first.
If other mobo can pass more BCLK speed, IOH is not so good.
But same BCLK wall, it's CPU limit.

If you want to more BCLK speed, please try as follow setting.

IOH Vcore: 1.40v - 1.46V
ICH Vcore: 1.15v - 1.20V
IOH & ICH PCI-E V: 1.60V
(Please be care of NB & SB chip temp.)

Great thread, thanks guy's.

Does anyone know if it's possible to connect an 8pin 12v from another psu into the second slot? without my REXIII blowing up My psu only has one of these connectors.

How about change molex to EPS 12V like as follow cable?

Good idea, thanks mate.

I have an "Asus Rampage III Extreme" with a i7 980x and 12Gb of RAM the system runs fine, however I have a major problem booting when Overclocked. At stock speeds it will always boot, but when overclocked it often will not boot. It will click as if about to start up and the fans move for less than a second then it stops. The board is powered, but it will not startup.

I have to either turn off the PS and drain all power to the MB then turn it back or, or worse reset cmos, turn off the PS drain all power and then turn it on. Once on the system is 100% stable, the problem is getting it to boot up. I need to understand if any voltage could be a problem during boot, but no other time. This problem seems to be getting worse with time use to happen once every 20 restarts now it is like once in 5 restarts. Again this is only a restart issue not a running issue, as once started all is fine. I'm on BIOS 1005.

Ideas?

I have had same problems but for me bios 901, those problems dissapears.

Ah, the SS is probably what pushed you past huh?

Once my weather gets cold enough again I will try this for a late night run, thank you!

Would those volts put off too much heat for a water block to whisk away? I would like to put my entire system under water (mobo, board, gpu) with a 480, 360, 240 radiator setup so I can have a very silent PC with still great temps. I hope those temps will help me push a higher BCLK with stable QPI in non-slowmode.

Great thread, thanks guy's.

Are you looking to do so for benching purpose, or just for everyday purpose?
