The SB Voltage is it also at 1.05V using Auto int he BIOS?

Try with more CPU and NB Clock Skew. The NB Voltage and FSB Termination Voltage looks to high.

To give you an idea. The screenshot with my Q9650@4.5GHz and DRR 1201MHz with tRD 7 is with CPU Clock Skew Delay 600ps and NB Clock Skew Delay 500ps. So lower the voltages and try to boot or run MemTest86+ Test 5 with less voltage and try to find out what values you need for clock skew.

**kuebk** · 01-04-2011, 02:57 PM

Nothing bad with using high MCH voltage if you can keep it cold, but I hope you are not using FSB Termination Voltage at 1.52 for normal use.

Just my luck, this morning i did a quick test before goto work, Then 1h later had some liquid on the floor, for no apparent reason something was leaking from here.

Try with these memory timings.

  Refresh Period		 [Auto]

Refresh Period should only be changed when it's stable

These are the memory timings from the Gigabyte GA-P45-UD3P and when you also use MCH Read ODT 11T you can use the lowest possible stable NB Voltage.

I'm currently running a test to find out if it's really stable with MCH Read ODT 11T. If all goes well and it turns out to be stable then I'm going to have to contact ASUS to add it to the BIOS.

**leo27** · 01-05-2011, 03:30 PM

Sounds like yet another round of long delays in getting ASUS to even release a BETA BIOS with the ODT Timing.....go for it A-Grey

**Alien Grey** · 01-06-2011, 04:47 AM

The question is if it's important to have MCH Read ODT available in the BIOS with different values?

Yes, it is and it's going to be necessary to try to have it stable at FSB 500MHz.

MCH Read ODT 11T

MCH Read ODT 8T

As you can see it's stable with 0.04V lower NB Voltage and MCH Read ODT 11T and it isn't with 8T. Stability improves a lot with longer MCH Read ODT timing at high FSB and we're going to need it if we want to try to have it stable running with FSB 500MHz.

There's also DRAM Read ODT and DRAM Write ODT but I didn't test it yet if it's better with a different value.

All these timings should be added to the BIOS so we can choose the value that we need to have it stable running.

**leo27** · 01-06-2011, 02:55 PM

Good find A-Grey, so adjusting the MCH ODT doesn't impact performance??

Now we just need ASUS to add it

**JohnZS** · 01-07-2011, 12:03 AM

Interesting find Alien Grey

I have asked ASUS if they can implement a way of altering the MCH Read OTD in the Rampage Extreme BIOS, but sadly they ignored my request

I'm getting the impression that all BIOS development for X38/X48 has halted and ASUS are only working on P/G41/43 based boards on the 775 platform.

No, it doesn't have any impact on performance. The only little performance loss is because of using the more relaxed ASUS Extreme memory timings to have it 24/7 stable.

I've asked ASUS to add the MCH Read ODT and DRAM Read/Write ODT to BIOS 0001. The reason I'm asking to also add DRAM Read/Write is because I think that these are also going to be very important to find memory stability at higher clocks. It's necessary to have it in the BIOS because at higher clocks it's a pain in the ass to boot and have time enough to change the timings.

I don't expect an official BIOS with these timings but I think that an unofficial BIOS should be made available. I think that ASUS ROG already had enough bad publicity and that releasing such an unofficial BIOS would be a major step for them to regain our trust.

ASUS ROG products should be what we want and not what they want us to give.

**JohnZS** · 01-08-2011, 05:05 AM

I agree, but they do not listen to us on "legacy" platforms anymore

Anyway thank you for your extensive research into the MCH Read ODT, I have applied a similar fix to my Rampage Extreme.
The memory address is the same FED14290, but the value you have to change is slightly different, I have to change 778 to 77B, I will post this in the Rampage Extreme thread and credit you for the discovery.
John

**Alien Grey** · 01-08-2011, 07:56 AM

It shouldn't be to hard or to much work for ASUS to add it in the BIOS. They don't have to do any research or testing. Just add those timings to the BIOS and mail it to me.

**Alien Grey** · 01-09-2011, 03:25 AM

It's MCH Read ODT at 8T that is limiting your overclock. Higher temperature needs a longer time to keep it stable.

Today my room temperature is 5° Celsius higher and I notice that I've got trouble to keep it stable running. Using MCH Read ODT 9T fixes the stability problem.

I also tried with changing DRAM Read and Write ODT but that's a bit difficult because I can't test it with MemTest86+. To do that I really need those timings in the BIOS.

I think that an MCH Read ODT setting in the BIOS from 8T to 16T should be more than enough to fix all our stability problems. I thing that running the board with 8 GB memory can benefit a lot from a longer DRAM ODT Timing.

**JohnZS** · 01-09-2011, 05:03 AM

Good thinking Alien Grey
It would be nice if ASUS could add MCH ODT, DRAM ODT and DRAM Refresh TREF to a BIOS shortly for both the Rampage Formula and Rampage Extreme.
This BIOS update would not only let users squeeze more performance and stability out of their PC's, but it would also give the ROG brand a good reputation for longerm support and listening to the userbase.
Please do continue to push ASUS for this

I will try again next week too.
John

**Alien Grey** · 01-09-2011, 05:44 AM

We bought these boards to do some serious overclocking/tweaking and paid a premium price for it so the least we can expect is that it has all the overclocking/tweaking features in the BIOS.

I'll give them some time to give me an answer on my request but I won't leave it like it is because these are for sure the features that are going to give us the performance boost to do the same or maybe better than the P45 boards.

I keep my fingers crossed. I hope that Intel is going to replace it with a good batch.

how do i change the MCH Read ODT
Dont get it. sorry . it is a noob question.

Hey all,

I just thought i'd thank you all for all the info in this thread. I havn't posted much, but have keenly been following whats been happening. I'll be moving onto a i7-2600K now, but the Rampage was awesome so thank you all for the tips! I would have never got my Q9450 to 4Ghz without the tips provided in this thread!

Only after i get mine at 9Ghz should greg gets a new one.

It just makes me so #"¤%%!%&/%&/ that mine is stuck at 3.9 so as soon my bonus kicks in, in Feb will go

for the Intel Core™ i7 Quad Processor i7-2600
EVGA GeForce GTX 580 1536MB PhysX CUDA
Hell yes, i wll get 2 of them..

What??? Are you kidding me?

if you do that ill go for an X68 with 12core on it , quad sli, 1tera sandforce 2000-series

ill kick your ass

BTW how much ram should i buy

**neo_rtr** · 01-11-2011, 06:59 AM

Just let it be man. You will burn it once again. Let the professionals play with this kind of things..
Dont make take up the pictures from your burned M/B

You will probably need 128K of ram.

I think 64k is ok, i might use a commodore 64 instead

BTW i saw your post with the leaks you have...Think possitive soon you will have your own swimmingpool (uv blue

)when your room will turn into one
