X48 Rampage Formula Preview.

That's .

Good work.

You can try to lower some voltages now.

Or go higher on ram, what wouldn't be a bad option.
But first I need to get some fan to throw some fresh air on MEM cuz they are gettin' pretty hot while benching.

BTW: Does MemSet save Clock Fine Delays too?

EDIT: BIOS 803 still doesn't let set tREF or did I miss something?

No. You have to use Bar_Edit for that. I don't know what registers you have to save and load to do that.

I think that mikeyakame or SoLoR knows how to do that.

I know the register offsets which hold these values, and I can explain the few that I've worked out, but I still cant for the life of me figure out the method for obtaining the actual fine delay in PS for each DLL table entry. I've worked out where I think fine delay ps bitmask is, and where some of the manually input phase degree offsets are set. I still can't get consistent results reversing the register values though.

I've run out of ideas on how to get the correct reverse data from the bitmasks/hex value. I believe I am missing the key element to how they are input by Intel, all I've got is educated assumptions to work with.

All he needs is the register offsets that hold the DRAM Clock Fine Delays to know what register to save in BAR_Edit so he can load them automatically at next boot to always have the same value.

This probably works very well when you don't have a dual boot configuration with Linux like I have.

No, you didn't miss anything.
ASUS thinks that we don't need it.

Quick one:

I've got some:
2x2gb OCZ Reaper 1150mhz
Q6600 G0 VID 1.325 ( Watercoolerd)
9800GTX ( maybe a future Crossfire or GTX275)

I want to squeeze 3.8ghz minimum, of my Q66. In water.

Rampage Formula or P5Q deluxe?
For 20 bucks of diference, Crossfire 16/16, LCD display (really useful) Reset BIOS button, STALKER...
Worth it?

or would de p5q be more easy to get 3.8 or beyond?

When you've got a Q6600 that can run at 3.8GHz it doesn't matter if you buy the Rampage Formula or the P5Q Deluxe. It should run at 3.8GHz on both these boards.

Choose the board that you like the most.

Anyway I would go for Rampage Formula.

Problem is you can't just change those values on their own.

The bold/underline are fine control delay/fine clock delay.
The underline are registers of interest for possibly phase degree offset.

[kuebk]

Is anyone running any 2x1gb kit @ 600mhz? If so I would be pleased to get screenshot with factory spd/timings as long with your current timings.

Want to compare which timings I could lower instead of trial 'n' error whole week. :p

Especially I'm interested into tRFC.

EDIT: Started the fight with timings, so far I've lowered the PL to 6, and Prime95 blend goes pretty good but also my ram gets pretty hot.

A-Grey how hot is your ram while benching? Do you have additional fan to cool ram?

It doesn't matter if you can't change the value. You can change them with DRAM CLK Skew in the BIOS and once you've found the right DRAM Clock Fine Delays you can save those register offsets in BAR_Edit.

The Thermal Sensor Cable connected to OPT2 is measuring my memory temperature. I've got a 250mm side panel fan that blows fresh air to my memory. This gives me a temperature drop around 8-10 degrees Celsius.
The temperature of my memory is around 30-35 degrees Celsius under full stress with the side panel fan.

If you want to cool your memory take a look at this memory cooler from OCZ.

In Prime95 Blend the highest temp which I've seen was 45*C with 2.4v and without fan what comparing to your 30-35* with 1.8v and fan doesn't look very bad.

[Mikefra2008]

A-grey what divisor you use? and fsb strap you use?

I´m running some Kingston HyperX PC9600@600MHz (1200MHz effective) 555 15 tRD6 Strong DRAM Static disabled without any problem.

I´m at work now so the only screenie I have with my settings is this, when I get home I can get you some more info.

There is a new BIOS available for the ASUS Rampage Formula.

BIOS History

[ 0902 ]
----------------------
Support new CPUs. Please refer to our website at: http://support.asus.com/cpusupport/c...Language=en-us

You can download BIOS 0902 here.

This time the new BIOS release is faster than the reply on the mails that we've been sending to them.

Please tell me that they added tREF.

[mikeyakame]

Please tell me that they added tREF.

Well tREF doesn't need to be adjustable option, rather they just need to write assembly function to self track DDR frequency automatically. Ie the value is changed when DDR frequency changes. THat's the correct way to handle it.

Doubt Asus has done anything about it though, they are hesistant to copy working assembly code from other bios source packages to add features...Just imagine the likelyhood of having to actually write new source functionality, especially since the board has EOL'd some time ago. If its added then great though. My DFI bios does it properly, Asus just aren't bothered because it's not a huge deal. Correct tREF doesn't make a big difference, rather it just reduces the amount of bandwidth on the FSB that is utilized to fetch lost memory data if self refresh turnaround is too short. Reduces memory access through MCH a little too. It's more an optimization than a difference, but every little bit counts when it's wasted for no reason at all.

[Alien Grey]

Please tell me that they added tREF.

They didn't.

There is no visual difference in the BIOS.

[kuebk]

Nor didn't add A1/A2/B1/B2 skews?

[Alien Grey]

Nor didn't add A1/A2/B1/B2 skews?

No, they didn't.

[Alien Grey]

The problem with the DDR +1200MHz seems to be fixed in this BIOS.

No need to Delay DRAM CLK Skew on Channel B with 50ps to run Linx stable at 8 X 465MHz, DDR 1239MHz and tRD 6.

This is great.

Let's see if it can stay stable now. When this can be done and someone can confirm with a Q9650 that he can run it stable now with DDR +1200MHz and tRD 6 we're back in business and maybe take the lead.

[SoLoR]

It seems they locked setting of skews with bar_edit in this bios 0902 (or maybe address got changed ?), also it breaks old OC profiles.

[Swiftes]

I am tempted to flash my Maximus Formula with the Rampage Formula BIOS. What gains would there be?

[RedBull1985]

uhm,does that mean the Clock Skew settings are not available anymore in the new BIOS?
