thanks a-grey i'll give it a shot later in the week

Did you end up getting your ram to run higher than 1200mhz, and whats your final thoughts on bios 902?

Yes, I did. It runs fine at DDR 1239MHz with 1.9V. I'll try to run my Q9650 at 9 X 465MHz later to see if I can get it to run stable with DDR 1239MHz and tRD 6 or tRD 7 and all Phase pull-ins enabled.

[leo27]

is there any benefit going to bios 902 from 803??

[kuebk]

I don't think so.

EDIT: A-Grey what mch voltage do you need to stabilize 400fsb, 600mem 5-5-5-15 trd6? Could you please check it for me? Looks like I need 1.45v what looks pretty much for me.

Has anyone tried removing the ROG logo from the stock SB heatsink? Is it even possible? It looks like it's severely hindering the SB's heat dissipation.

I do, Is easy to remove, but you must do it with a hear dryer (be carefull) and pull from the heatsink.

This you must do with hold headsink out from the motherboard.

Only if you need DDR 1200MHz+ and tRD 6.

I've been running for moths now with BIOS 0902 and everything runs perfectly stable.

I've been running a few tests and I didn't need more voltage on the MCH to run LinX for a few passes stable.

I did a test with CPU Clock Skew Delayed 200ps and NB Clock Skew Delayed 100ps. It stayed stable but there was no need to dial in a delay.

I tryed with CPU Clock Skew and NB Clock Skew on Auto and everything was running smooth.

I have to say that I only did 3 passes in LinX but I think it should be enough to see if it's really possible with lower voltage.

The 266MHz strap isn't the problem. It must be something else. Perhaps your MCH temp is to high (my MCH temp was 34° Celsius during the test) or you need that high voltage to keep your memory stable at 1200MHz.

You could try with your memory running at default speed and see if that would help to keep it stable with lower voltage. When that doesn't work try to find a way to lower the MCH temp to see if that's the problem.

So if I understand correctly the only way to safely remove the ROG logo is with the heatsink removed from the motherboard? My UD3P's NB plate came off with just a screw driver because it only uses double sided tape.

This should too, haven't tried myself but afair someone already done this that way.

You can do it with the heatsink on.........but do it at your own risk...
The think is, that logo is very "glue" to the rest of the heatsink, so if you force the logo to take it off you can break something (like the SB of NB)...

Good Luck!!!

Alright, thanks.

I've removed 2 of them with a screwdriver no problem at all.

Now i have run into a problem in that i was unable to reduce the memory timings (4-4-4-12 at 1.92V in bios) with a PL7, however if i run PL8 with all phase pull-ins as above then i can achieve the timings and voltage shown in the settings above (4-4-3-9 at 1.84V).

I take it PL8 with all Pull-ins is equivalent to PL7?????

to A-GREY
I've read that you use UT2004 to determine the FSB termination voltage. What settings do you use in UT2004????
and do you run it with Prime95 small fft's or large fft's????
an explanation of the procedure would be appreciated.

Lastly is a CPU GTL of 0.65x recommended for a 65nm processor or is 0.63x advised.

Thanks for your help and keeping up with this thread. It is a invaluable resource for overclocking this board.

I've just been testing out my system with UT2004+P95 in blend and the problem i have is that P95 keeps failing.

As you can see above i am stable for 5hrs on large ffts and 5hrs on small fft's as well as 25 passes of linx. I should also say that the memory has passed 8 tests of Memtest86+ test no5 as well as 400% of HCI memtest.

i have tried increasing the FSB termination.
1.30V lasted 5hrs
1.32V lasted about 2hrs
1.34V lasted about 2hrs

after seeing this i decided to try lowering FSB termination to see if higher wasn't better

1.26V lasted 1hr

I would appreciate any advice as to what is causing the instability with P95 and UT2004 or do i just need to play with FSBterm some more????

If you lower the FSB termination Voltage you should check it first with LinX to see if that stays stable.

Where does it fail in Blend Mode? Is it Small or Large FFT's?

[leo27]

this is the log for the test (P95 blend + UT2004 in 64-bit) with FSBterm at 1.34V (known stable in Linx)

Try with 1 step higher NB Voltage or Memory Voltage or both.

Edit: If all goes well I finish mine at 4.05GHz in a few hours.

[leo27]

will do thanks A-grey, and thats awesome news hope it goes well

[leo27]

Increasing the NB voltage by 1 step to 1.39V worked a treat. I'm stable now for 10hrs with FSB termination at 1.30V. When i have time i'll try to lower the FSB termination.

The Thermalright Mosfet Coolers fit on the ASUS Rampage Formula. I have them on my board. You need a HR-09 U Type 2 and a HR-09 S Type 2.

There are a few pictures of my system on the ASUS Rampage Formula forum. They aren't the best quality pictures but I don't have a good digital camera.

Is there any possibility to mod 802 bios so by default it would be setting the highest possible tREF (16k) instead of 3120?
