since you guys got this board and you all the know the dos and donts im gonna start off fresh does anyone feel like giving me live tech support via skype or another application on my laptop to guide me when you have time like to not install ai suite or to and simple like that and how to configure my set up to get the best out of it. i am in dire need and it would be a great learning experience for me.

[Engage]

wow at my grammar and english. please excuse me as i am so tired i am about to pass out lol

i happened to be looking through the bios yesterday and noticed that ACPI 2.0 support was disabled.

Is it a good idea to have this enabled?? I know it'd require an OS reinstall but it'd be good to know when that time comes

Engage - Welcome to the forums, nice to have you aboard! Unfortunately I don't have Skype or any other application that could be used to give you live support. Granted it won't be as easy but there is a ton of great information throughout this thread that could help get you started. Feel free to PM me if you have any specific questions regarding your motherboard (by the way what hardware do you have)?

It's better to enable ACPI 2.0 in the BIOS when you are using Windows Vista and probably Windows 7 too.

I've read somewhere that if you leave it disabled it disables ACPI completely.


If it's really necessary on an overclocked system is something that I don't really know.

The BIOS controls the voltages when you overclock and all power saving features don't work anymore so I think that it isn't really necessary to enable it on an overclocked system.

thanks for the reply A-Grey. Did you end up getting your 285gtx up and running??

[D.Drona]

OH GREAT thats all I need another board .
Thanks for the info though

I built one of these boards a few weeks ago and it was fine no probs at all.
Dont suppose it could be a ram compatibility issue ??? the ram is a few years old now.

I have a RAID 0/1 arrays set up on two disks for my Vista 64 OS under Intel Matrix Storage.
I am trying to connect a Sans Digital Tower Raid TR8M. I installed the bundled (Port Multiplier) controller PCIe card and its driver under windows vista64
the card & drivers are recognized and funcitoning properly according to Device Manager.

In Bios (when TR8M IS connected) - under Boot Priority my choices are limited to:
#1 - RAID: 0:4:00-0WDC WD15EADS
#2 = CDROM
#3 - DISABLED
#4 - REMOVABLE DEVICE
I can not find any option in Bios which might (for instance) change which RAID array appears in #1. As shown above #1 is the TR8M controller card. It is automatically inserted as the "default" boot RAID array, and since there is nothing on it I am unable to boot. The TR8M "highjacks" the "boot from RAID" arrary option.

In Bios (when TR8M is not connected - under Boot Priority my choices are:
#! - RAID: WDVISTA
#2-#4 are the same as above

#1 in this case is my origianl Intel Matrix Storage managed boot array, which is the one I need to boot into Vista64.

Responses from manufacturer:
The problem is on the ASUS Rampage motherboard boot sequence. Please try update the ASUS BIOS and then make sure boot sequence on both Hard drive field and Add-on Adapter. You can also check if there is any disable function to disable the boot from the Add-on card.

The boot sequence is always handled by motherboard. The card does not hijack or do anything to modified your BIOS setting. In other word, the card only tell the BIOS that the card is installed. It is up to BIOS to use it as boot or not. That is why updating BIOS may resolve/help your issues.

Disable add-on card is mostly under boot sequences. BIOS implement differently so I cannot pin point to the location for you.

My question to the knowlegeable is: my current Bios is 803; will an update to 902 solve my problem as the manufacturer sugggests? Or is there a setting/solution that I am missing.

Thanks in advance.

Note current setting: Bios Main - SATA Configuration - Configure SATA as [RAID]. Should this be set to AHCI? Would that solve the problem? Can I change it after my Vista64 had been installed on Intel Matrix Array?

[h2OKewl]

For posterity, here is the workaround I devised.

Boot to Vista without TR8M plugged in. Install software RAID for Sans Digital (note UAC must be turned off or install software outside of Program Files folder); configure RAID array. Partition Disks. Good to go. (Not sure if I can restart with TR8M plugged in but if not no problem to unplug and then plug back in after Vista boots). At least I did not have to risk a Bios upgrade.

just a quick question. Will this board be able to clock a dual core cpu at 600 fsb with 4x1gb micron d9 when the board is water cooled for 24/7 use?

[crusoe]

Hi everyone,

After my IP35 Pro crapped out a couple weeks ago, I replaced it with a Rampage Formula that I acquired new for a mere $140 because of the board's age. I had my e8400 at 4.05 GHz on the P35 board, and I'm shooting for something a bit higher on x48.

Currently, I'm at 460 FSB, 1.3vCore, 1.31 vNB, 1.24 vTT, 1.52 vPLL, and 48-49c max under OCCT load with a Mugen 2. My GTL ref voltages are .63 for both the CPU and Northbridge. I idle at 40c, but I believe that's inaccurate due to a stuck temp sensor; when I'm at 2% load, speedstepped down to 6x, I still idle at 40.

Anyway, 460FSB is completely stable at relatively low volts.
But when I try 465FSB, I get errors even at 1.35vCore, 1.41vNB, etc.

I'm using PC8800 G.Skill PI memory, so I know that's not the bottleneck.

Any thoughts about breaking this FSB wall? With a dual core, I've read that the Rampage Formula should be capable of 600FSB in extreme cases, although 500FSB would be great IMO.

Thanks.

Try with NB GTL at 0.67X and use one of the latest BIOS revisions. BIOS 0701, BIOS 0803 or BIOS 0902.

BIOS 0803 and BIOS 0902 have CPU and NB Clock Skew available.

[crusoe]

I'm currently using 0902, and I just tried with .67 NB GTL but no difference.

What effect do clock skews have?

[Alien Grey]

thanks for the reply A-Grey. Did you end up getting your 285gtx up and running??

No, I didn't. I don't hear anything from EVGA. No explaination why it takes so long or what they are going to do to fix the problem.

[Alien Grey]

I'm currently using 0902, and I just tried with .67 NB GTL but no difference.

Try with FSB Termination Voltage around 1.22V real for FSB 465MHz.


The CPU and NB Clock Skew delays the time when the clock starts.

Try with CPU Clock Skew Delay 100ps and NB Clock Skew Normal. The CPU Clock is going to start 100 pico seconds later. That could be enough to have it stable.
Also try CPU Clock Skew Delay 100ps and NB Clock Skew Delay 100p or CPU Clock Skew 200ps and NB Clock Skew 100ps.

[kuebk]

There is no need to mess with skews and gtls if you aren't at >500fsb.

Try to do 8x500, set all voltages to lowest possible except the vtt which should be set to 1.24v then start to mess with cpu vcore.

hi all just got this board today (replaced my dead gigabyte x38 DQ6)

Quite like it so far, it able to hit 500 fsb easy with my quad Q6600 on stock air cooler so once i get a new psu( it died too ) it will be getting stuck on phase to see what i can get out of it 24x7 stable old board was 4.2 stable all day long at 1.53v so hoping the same or better with this mobo.

starting to trawl this thread for info on people's settings for overclocked quads

wish me luck and i will report back with my setting and how good this board is !!!

[Alien Grey]

Hey guys I'm working on a new 24/7 stable overclock.


Remember a few months ago when I said that I've seen amazing things with BIOS 0902 and my Q9450. My Q9450 couldn't take the speeds anymore and was holding me back from higher overclocks.

With my Q9650 this isn't the case and now I'm able to shoot for FSB 470MHz and DDR 1253MHz with tRD 6.


I'll post some pictures later.

[kuebk]

Better post your bios settings using which you achieved >1200 on ram.

[Alien Grey]

I'll do that as soon as I've got it running stable.


The Q9650 seems to be doing fine at 4.23GHz. I could do 5 passes LinX stable. It isn't enough but it gives me an idea if it's possible or not. The G.SKILL F2-9600CL5D-4GBPI is running MemTest for Windows stable for over 100% at DDR 1253MHz and tRD 6.

It's a good start but I don't know if I can keep it stable at these speeds for a long time. I have to run more stability tests and that's going to take a lot of hours of trial and error.

[leo27]

Its good to see this thread still going

As it happens i've been messing around with my current oc as well. So far i have been able to reduce vDRAM from 1.84 to 1.8 and vCPU to 1.40675 (1.392 in windows) from 1.4125 (1.400 in windows).

I managed this by finally getting around to reading the thread about setting GTL references. It supprised me to know that FSB term should be set around 0.02-0.04v higher than vCPU (from mikeyakame) at least on 65nm CPU's anyway. Apparantly thats how vTT (or FSB term) is supposed to work.

I can pass around 15 or so passes of LinX with vCPU set to 1.4000 in BIOS which is around 1.875 ish in windows. With more time i think i can get this to work out just need to play with vTT some more.

And for 65nm CPU's and relatively low vNB (1.39v) i found NB GTL of 0.63x and CPU GTL of 0.65x worked the best.

Hopefully i can get vNB down some more as well.

I have a question for all of you - what cooling are you using on the mosfets? I'm pretty sure, that they are overheating above 470Mhz (483, to be more accurate). I'm using the stock cooper sink, while i have waterblock on the NB. Any suggestiongs?

A-Grey i wish i had your lowVol. chip in my hands

By the way our g.skills cost about 105€-130€ in Germany right now:

but the thing is can 4 sticks work without having stability problems???
