I have change ACT from moderate to lighter for better stability and if ASUS would ever give us some extra ODT bios settings we could use lower volts (cooler system) or i could run my 8gb gskills with having stability problems as i now have...

@greg.m

Be careful with high FSB. If you want to use FSB 480MHz as your 24/7 stable you should try to find out what value you should use as MCH Read ODT because I think it isn't going to be always stable with 8T.

What happens when you try to use lower (Auto in BIOS) CPU Voltage at FSB 450MHz?

Ill prove both 2 - to adjust odt value and boot with cpuvolt set to auto

Hi Greg,
I know it is OT but I hope you don't mind if I ask you if your HD 5970 doesn't like the ATI-drivers since the 10.11 version like my HD 5970 does ?

[Spyrus]

If you're not afraid to destroy your board you can give it a try.

You are going to need 1.70+ Volt at FSB 500MHz to have it running with BIOS default MCH Read ODT 8T. You're going to have to keep the NB very cool and you're going to have to keep to room temperature very low. But that shouldn't be a problem if you take your system outdoor this time of the year.

Or you can try to tweak the MCH Read ODT with BAR_Edit to find better stability and lower volts.



If you could boot with lower tRD with a BIOS release before BIOS 0902, but couldn't run it stable, than you should give it a try.

Well, i think that following values might prevent PL=6
DRAM Static Read Control [Enabled]
Ai Clock Twister [Moderate]
but they give better Bandwidth from Disable/Light
Have not tested that yet, but i was looking at greg.m settings and compared to them

Edit: read some earlier posts and i saw that PL6 is possible for strap 400 and lower fsb
So, in my 9x450 i can't put in there PL6

Though according to this http://www.anandtech.com/show/2427/8
i can (6/5 divider)

That is true but I think that X at FSB 450MHz is going to be more than 2.0 and that is the probably the reason why it doesn't work with a tRD of 6.

Edit:

X increases with higher FSB so X at FSB 450MHz would be 2.25 and than it isn't possible.

You can try it yourself. Lower the FSB to 400MHz and keep the 6/5 and than you are going to see that a tRD 6 is possible because X is than 2.

After a clean install and with the latest ccc drivers everything seems good. But i hope that you have a good cooler (water or not) for your overclocked card...

[greg.m]

im gonna get crazy i can do 20 linx passes now and next day im getting bsods, not errors just bsods after some passes. everything more than 475 gives me problems...i have a so good q9650 in my hands but that f...ing board doesnt help att all.

I personally believe this is a problem with a lot of the 775 ASUS boards.
Difficult (or perhaps impossible to prove), but I swear some settings which are [AUTO] do not remain consistent after a COLD boot.

I.e. you input settings, stability test, fail, reboot, change settings, stability test, fail, reboot, change settings some more, stability test... and then everything checks out fine.
20x Linx
Hiper Pi
3dmark Vantage Loop.
3dmark 06 loop.

And then play a game for a bit, etc. Turn off PC at the end of the day.

Boot the next day, instant BSOD System Service exception or Stop Error.

POWER OFF PC (i.e NOT reboot), then power on and things are fine.
However if you reboot (reset or a quick power off and on) BSODs continue

I have had this happen on two ASUS boards, P5E3 and Rampage Extreme. It appears you are having a similar issue too.

Sadly nobody can prove this as it is so difficult to pin down.

Hi Greg,
I know it is ot but I am using the Accelero Xtreme VGA-cooler. Even Metro 2033 or CoD4 (MW) doesn't really heat up the card. The gpus won't jump over 55° C. The vram is cooled as well.
I am happy with the card and glad that I followed your recommendation.

Sorry guys, I know I was OT

GREG. Iam happy for your new CPU, i think is like the 3rd or 4th?? Any way. good job.
and as we spoken about it last . Gave it a try but nothing. So officially declare will never touch my pc again and any settings until next time around where i swap platforms. Thanks you guys for all the hard work and support on this board.

[greg.m]

Get ud3p!

Iwould certainly do that if i wouldnt have to buy new w-blocks and go through all that installation process ones more for a 775 system, its too late i think. Ill just wait a bit more... until x68 comes out

Bth here is my gpu-bios clocks/volts, 900/1300, 1.25v-VDDC, 1.15v-VDDCI.
You might wanna give them a try

I think i just have to live with that until my next build Ill probably go for a msi or gigabut board this time...and i hope that Alien Grey will follow too ...

[Fritz_the_germ]

Hi Greg,
if you are really thinking about a new board I would recommend a Gigabyte. I am playing with my UD-7 for a year now and I love it

[Counter CS]

Hi. I have a little problem with USB ports.

When i plug my external Hard Drive it only light up blue led, but if i plug the same Ext-HD on my EeePC 1005HA it starts spinning, and get recognised ican access with no problem.

I think there is something messy on USB ports.

I try on BIOS to change every settings related with USB but with no success

How can i fix it ?

[JohnZS]

Are you using the Front USB Ports Counter CS?
I have the same problem with my Rampage Extreme and P5E3 Motherboards. ASUS Support blame "attenuation" and it is unfixable.
However the rear ports built into the board work fine.
John

[Counter CS]

NO, i tried all the ports USB, none works with ext-hd

Is this a joke frome Asus or what ?

[JohnZS]

None of the ports work? That is weird...
Have you set BIOS EHCI Hand Off to Disabled? (It is within the USB section).
Are your ports running at [Hi Speed]?
Legacy USB = [AUTO]?
Those settings should help.

Hi, im using ports at "Full Speed" also tried "hi speed" everything enabled on USB section

[JohnZS]

[Hi Speed] is faster than FULL SPEED. (seems strange, but that is the terminology used)

Have you tried setting the EHCI Hand off to disabled?

One more thing, how many USB devices do you currently have plugged in?

It could be you need to unplug, one or two?

John

[Counter CS]

I only have the mouse USB. Its MX510

[JohnZS]

Hmm, which port is it in?
Top rear near the PS2 Keyboard port?
Are you using the latest firmware for your mouse (if there is one?)
John

[Counter CS]

John

Yep, 1st port USB on top left PS2 keyboard

My mouse doesn´t have firmwares.

Tryed all the ports on motherboard, nothing make the disk start spinning .

Weird

EDIT: i had the last BIOS frome Rampage formula same problem .
