Any voltsuggestions for running 500fsb?

Something to start with?

[greg.m]

Het got a 1500W PCU only to blow it on the 2nd reboot.

I will start a shop and sell him computer parts!

You naughty boy the first thing ill buy is your QX6700 - its a little piece of ....(guess the word)


Solution:

Right answer is.... art

Will be hard to hit 500fsb with quad, imo vMCH > 1.45, vCPU and VTT stricly depends on your CPU.

[Alien Grey]

i run a double instance on the mem test, pass 110% and no errors!

put default settings and initital results with linkx where stable but had to stop the test at that point.

If you overclock your memory run MemTest86+ V2.11 and try to get it stable before you move to your OS. Than you can try MemTest for Windows.

When you know that your memory is stable run 10-15 minutes Prime95 Small FFT's and 10-15 minutes Prime95 Large FFT's. When you can run that stable you can start with Linx.

I always try to run 25 passes of Linx before I try to run Prime95 for 6 hours.

500fsb depends on your CPU. If you are getting lockups you are either walling the CPU or your gtls/skews are the problem.

I've had a Q6600 boot to windows at 510mhz FSB on this board, but only with 2 cores. It dropped the other 2.

[screwtech02]

I'm so done with this board, puttin my MFII back in, I cannot get this setup to run 4.0/1199 stable for the life of me, unless i overvolt to high-heaven... MFII will at least have seperate core gtl adjustments, and a bettter power regulation.....

[RedBull1985]

I think 500 FSB is a no-go for thi9s mobo + Quad....even 500x6 is throwing in errors and lockups with stress testing.Tried each and every combination of voltages,taking NB from 1.43 to 1.73 - to no avail.So, I am happy sitting here at 495 x 8.5 and trying to find stability with the 0902 BIOS and reducing voltages bit by bit.

Don't skip page 41, the most important screenshots are on there. I used more volts than I should have because the dude challenged me and I was just out to prove him wrong and move on to other things. At least if nothing else, this shows it is more than doable. I've done it with Q6600, Q9550, and Q9650; all with 8GBs to boot.

With DDR 1199MHz and BIOS 0803 I don't think you will get it stable. We need the DRAM CLK Skew on Channel B fix for that. This BIOS can't run stable with high DDR speeds.

Try BIOS 0902 that has that fix. Maybe you've got more luck with that BIOS than I do.

Correct My memory is running 100% stable at 1081Mhz , I tested that by running the windows MEMTEST, and i also run two instances of the program at the same time..with no errors.

The fix to what?

[Alien Grey]

The fix to what?

To run your Memory at high frequenty.

With BIOS 0803 you've got the problem that with your Memory running at high frequency you have to start delaying Channel B. A delay of 50ps on Channel B can partially correct that problem but the Memory will still make some errors there is still a small sync problem between Channel A and B.

Without the delay on Channel B it isn't possible to have your Memory running at that higher speed with this BIOS.

With a faster CPU speed you will see that problem much earlier. That's why we can run our Quads at 3.6GHz and DDR 1199MHz with tRD 6 without problems but if you run your CPU at 4.05GHz with a 9 multiplier you won't get it stable anymore with DDR 1199MHz.

BIOS 0902 corrects that problem and there is no sync problem anymore between Channels A and B.

With fixing that problem they created an other problem.

This is what I think happens in BIOS 0902. With fixing the sync problem between Channels A and B they moved the problem to the NB and created a problem between the CPU and the NB. This is probably the reason why I'm always with the wrong CPU and NB Skew.

Advancing the Skew a little bit in the BIOS for the NB might fix that problem.

But hey... I'm not a engineer and I don't know all the technical sh*t and this can be totally wrong.

Correct My memory is running 100% stable at 1081Mhz , I tested that by running the windows MEMTEST, and i also run two instances of the program at the same time..with no errors.

Try to run Prime95 Small FFT's to adjust your CPU Voltage and your FSB termination Voltage and Prime95 Large FFT's for your NB Voltage.

When you've got that stable for 10-15 minutes you can run Linx to tweak your GTL's in combination with the FSB Termination Voltage and adjusting the CPU Voltage.

When you can run 25 passes stable in Linx you can go to Prime95 again and run Blend Mode to see what needs to be done to keep it stable for a long time.
When you still fail Large FFT's it is your NB or FSB Termination Voltage.

Thats for the feedback. Will put down some time on this.

How am i supposed to use the ASUS EZFlash Utility ? I wanna flash back to 0803 and it seems to be the only option.Shud i make my USB bootable or something?

[RedBull1985]

^^ ah sorted it myself.Now back on 0803

[Alien Grey]

I've got a mail today from one of the ASUS engineers. He wants to know what the problem is with BIOS 0902.

"Problem with BIOS 0902... I don't know we're all using BIOS 0803"

To make a long story short. I told him that it's impossible to run stable with that BIOS.

That I already informed ASUS about the problems and that they shouldn't release it as a Final BIOS but that nobody seems to care and have no time to reply to me.

That we've been asking for god knows how long time to do something about the BIOS on the ASUS rampage Formula.

And of course that we aren't so happy with the current situation.

So, I'm hoping that the ASUS Engineer is going to take this serious and that they actually going to do something about this.

[Zucker2k]

Asus engineers need some real overclockers who can bring out the worst in their bioses, so they can catch them in time and fix them before release to the public. Key word: hardcore overclockers!

It's like I said before. They run some benchmarks and they are happy if they can finish them before the problems start.

It's easy to say that you don't support OverClocking. When you don't want to support OverClocking you shouldn't sell boards who can do it.

You are right. For every board they should have someone that is capable to find the problems in their BIOSes. There are guys enough who can do it. They just have to ask it and those guys would be happy to do that.

BIOS 0902 was only a few days available on their FTP before they moved it to the Official download page. That's to early because most problems can only be found after a lot of hours stress testing.

Mind if I add to your keyword

"Competent" Hardcore Overclockers.

They are rare and few inbetween.

Lol. How about dedicated, competent, hardcore overclockers? I woldn't mind overclocking systems for a career.

Hell neither would i As long as whomever wants me to do it, supplies me with a logic analyzer and the Intel Data Analyzing/PC Logging Software to go with it!

Without the proper hardware to confirm problems, overclocking blind is kinda pinning the tail on the donkey! Just hope that donkey doesn't turn out to be somebodies mother!

Thats for the feedback. Will put down some time on this.

Dont know what is going on. On a previous good and stable system after the move to 0902 then back to 0803 with the same settings iam having probs to get it stable.

Iam going up and down volts all over the place with no luck.
i will start taking down the OC to 3.4ghz now to see what happends

Reflash your board with 0803.

Remove your power cable from your PSU or disable it with the power switch if you have one. Do a Clear CMOS before you flash it.

Start your system and enter BIOS Setup to load Setup Defaults and save it.

Enter BIOS Setup again and flash your board again with BIOS 0803.

After flashing your board power it down remove the power cable again from the PSU or disable the power switch and do a Clear CMOS again.

Start your system and enter BIOS Setup again to load Setup Defaults and save it.

Now you can put all your settings back.
