It's a part of their strategy. The longer they wait to release something the longer it stays quiet. :DQuote:

Consider this the SCREAM!!!!!!!!!!!!
On another note are there any memory timings in our Bios that are better higher rather than lower (i.e like how tREF gives more performance at 16383t rather then 3120t)
I asked them when we could expect the new BIOS.Quote:

The longer your memory wonīt get a refreshing the higher is the risk that the memory will "forget" the stored datas.
Thatīs why the 16,383T should be used for benching - but not for the 24/7 use. Gaining stability a tRFEs value of 2,600T is even better.
Hello all,
I've recently attempted to OC my system using the 0902 BIOS but I wasn't able to get a stable OC at all. I've flashed my BIOS back to 0803 and set my BIOS settings to the following:
Ai Overclock Tuner [Manual]

I'm trying to get my OC stable at 3.6ghz but my system won't even load into Windows 7. If I down clock to 3.4ghz I'm able to boot into Windows but Prime 95 fails within a few minutes. Any suggestions on how to get my CPU stable at 3.6 or will I have to live with 3.4ghz?
Thanks!
For your BIOS problem.Quote:

If that doesn't work reflash it with the same procedure. This seems to work when you've got problems with BIOS 0902 flashing it the first time. Don't ask me why but it's a fact.
For your overclock. Does your memory need 2.2V for 1081MHz?
Run MemTest86+ and try to find out how much voltage you need for 1081MHz.
If you need 1.45V for the NB to be stable at FSB 450MHz with Ai Clock Twister Moderate there's a good chance that you experience the exact same issue that I've got at FSB 470MHz when using CPU Clock Skew Delay 200ps and NB Clock Skew Delay 100ps and that is that higher voltage on the NB makes it unstable.
The 100ps delay difference between the CPU and NB Clock Skew is the key to the high FSB overclocks with our Quads but we need a new BIOS that makes it possible to use it with FSB 450MHz+ without having to push the NB Voltage higher than we should need for that FSB frequency to have it stable.
Try with CPU Clock Skew Delay 100ps and NB Clock Skew Normal or both on Auto with Ai Clock Twister Moderate. You can also leave it with CPU Clock Skew Delay 200ps and NB Clock Skew Delay 100ps and try with Ai Clock Twister Light or Lighter.
You should be able to use Common Performance Level 7 with FSB 450MHz and DDR 1081MHz.
Thanks fritz and a-grey for the quick answer to my memory question
Also fritz i've been running a tREF of 16383t for almost 3 months and am HCI memtest 12 passes stable as well as 12 hours P95 blend+UT2004 stable so i guess my memory has no troble running with it
@Swiguy
As A-Grey said you vNB looks quite high for 450 fsb with Clock twister moderate, i need 1.42v at 425 fsb at clock twister stronger (clock twister really requires a large bump up on the vNB). If you memory is memtest86+ stable (run test 5 for an hour) then i'd say you need the BIOS we've all been waiting for.
Also which test of P95 is failing, is it smallFFT's or Large FFT's?
If smallFFT's the chances are its vCPU or CPU GTL's or your processor can't handle the clock speed (unlikely at 3.6Ghz for a q9450)
If largeFFT's then it could be vNB, NB GTL here's a rough guide relating to problem size
1024 – VTT or vNB
896, 448 – vNB
768, 512, 332 - VTT
Here's some information about the new BIOS.
The ASUS R&D team is working on new products and didn't have the time yet to make the new BIOS. The new BIOS will be released but we just have to wait a little longer.
I hope I can still test it with relative low room temperature to minimize the risk of damaging my hardware.
@greg.m
Where are you man. I didn't see you around for a long time.
Did you forget to put anti-freeze in your watercooling loop? :rofl:
I tried the above but I'm still freezing within a minute in Windows 7. Not sure what I'm missing here since I was overclocked to 3.4ghz (425fsb) on the 701 BIOS. Ever since I've updated my BIOS to 0803 or 0902 I've had a very unstable system... any other suggestions?Quote:

As I mentioned to A.Grey, I've had instability issues ever since I upgraded my BIOS from 0701. I even tried going back to 0701 and still freezing up :SQuote:

Man, i tell you its the beastiest beast i ever had. Crazy fps everywhere. I read a lot arround and there are many who has something to say but the truth is: ITS A BEAAAST:explode2:
That's the strange part... I had my system overclocked to 3.4ghz on 1.318v (BIOS) prior to my BIOS upgrade. Maybe I should provide a more complete picture of what happened.Quote:

I have verified that the new PSU has solid rails at 3.3v, 5v and 12v. Additionally, I insured I had all of the same BIOS settings when I was using 0701. I can't figure out why I can even stay stable in Windows 7 for longer then a minute now... I could run a 3.4ghz clock 24/7 with no issues before.
All of my temps seem quite good so there is no way a temp issue is causing immediate crashing/freezing within Windows 7. As for my BIOS settings now, I've set everything to AUTO pratically and have adjusted the voltages for the CPU from 1.3 to 1.45, CPU PLL from 1.5 to 1.54, NB from 1.41 to 1.55, DRAM at 2.1-2.2 (rated to run from 2.1 to 2.4), FSB term from 1.31 to 1.4 and SB all set to auto.
The only other options I've changed are Loadline = disabled and spectrum settings = disabled... nothing seems to be working for me though... perhaps I should try loading defaults, flashing to 0902 again, clear CMOS (i.e. remove battery for 30 min or so), load defaults flash again?? Any suggestions will greatly help me out since I'm totally stumped!
Thanks again!!!
It wouldn' hurt if you re-flashed to 902 however do this: set to defaults, clears cmos, set to defaults, flash to 902, set to defaults, clear cmos, set to defaults then try. I know its super cautious but at least it'd rule out a bad flash.
Second that, imagine what those are like in CrossFire, if one is a beast :D, it brings down whatever I throw at it :frag:Quote:

I most say that you are doing a great work hammering on those Asus bios engineers :up:, much appreciated :yepp:
@greg.m
I see, that's what you were doing all the time, benching that Sapphire OC 5970. They can say what they want but the 5970 is the fastest card around and it doesn't look like Nvidia is going to outperform it with their Fermi.
@Ghostleader
We need something to unleash the power on the ASUS Rampage Formula to get our Quads on high FSB. We can't stay behind. :D
@Swiguy
The reason I'm asking if you can get it MemTest86+ stable at FSB 425-450MHz is because if you can't the board might be slowly dying. Try it and also try it with one memory stick (test them both so you know that it isn't your memory that's faulty).
I didn't get a chance to test my memory at 425-450 via Memtest yet... I'm fairly certain the memory is ok and I'm starting to think my motherboard is starting to die like you mentioned.Quote:

I'll post my stock load temps when I get home.
Try to raise the NB voltage to range 1.61-1.69. Especially if you have the 4 slots RAM occupied. And make sure you have a fan blowing to the heatsink, or even better have it watercooled.
It appears I've resolved my stability issues... my new Corsair TX950W power supply was the culprit! I didn't really think this was the issue at first but when I exhausted pretty much every other option I figured it was worth trying a different PSU. I installed a temporary power supply which instantly improved stability... right now I'm running my system @ 3.6ghz at similar settings mentioned in earlier posts.
I'm going to look and see if I can exhange this PSU with the HX series from Corsair since the modular design appeals to me. Anyhow, thanks to everyone who assisted me with this issue!
What would be the max safe NB voltage that you'd use with this board for 24/7 use??
Obviously lower is better but when the new bios comes round i'm going to have a crack at getting 3.5Ghz outta this chip and hopefully run it as my new OC
1.65V is safe enough.
This is a copy of a thread i made on the asus forum
I'd appreciate it if any one here can help with this alsoQuote:
I've just installed win 7 x64 and whilst all the other drivers have worked fine (sound, network etc) the intel inf refuses to install properly.
I have tried version 9.1.1.1025 and 9.1.1.1023 and they both exhibit the same problem. The install says sucess, it even said to restart the computer but the drivers listed in device manager list a driver from 2006 (i have tried the -overall and -overite commands also).
Has anyone got an intel inf that works fine with win 7 x64 and the rampage formula
EDIT: Intel Chipset version 9.1.1.1019 says the computer doesn't meet the minimum requirements
