Perfect example that going up is not always the direction one should choose.

But for some time now been trying to get it to work.
My goal was 3.8ghz. At some point i did a cross flash as i call it to the RAMPAGE bios. 8202

It proven to be one of the best things ever. No i have not reach my goal but now days what ever i put on it it will boot.

Any way. been surfing alot to get some more info. This QX6700 is not so commons and by now almost no one using it.
In search of the sunrise has to redo bios settings and from what you can see from previous posts they where high.
So far i have managed to take them down a bit.

One thing i can tell you for sure is that 8x450 fsb needs that 1.50V FSB Termination Voltage. (have tryied almost anything and i found countless ways NOT to do it that way).
So 1.50V FSB and 1.53V NorthBridge works for me.

Also notice that the CPU Voltage is now down to 1.46875V / 1.54V CPU PLL

Iam quite sure that there is room from improvment.
One thing i did notice is that taking the CPU voltage 1 click down, I had to take the PLL 1 click down as well. If not, Prime failed on around the 7 or 8th loop.


Also when prime fails going up one click in voltage Do Not always work.
Will not argue that , just an observation. Be flexible! and take your time. It does take time this OC business.

Taken from the Rampage Review forum

Good stuff mate

I've seen quite a few MFs needing a lot of Vtt so I'm not surprised. Thats good news anyhow, all you can do is find what works for your board right.

Other thing is Asus reads Analog Vtt, which isn't all that much to go by as you increase Vtt voltage. Vtt voltage at the pins is a decoupled voltage, Analog Vtt is decoupled with Digital Vtt to give a final Actual Vtt voltage. I've heard of upto 0.1v difference at the pins with high Vtt voltages. So if you find you need that much Vtt, it's possible the actual Vtt voltage at the CPU and NB land pins may be much lower than what you are setting.

this is the lowest Prime 95 result i can get

FYI

Thanks A-Gray and mikeyakame for helping out with my questions, its greatly appreciated! By the way A-Gray how does Prime failing in SmallFFT's or LargeFFT's help determine what the problem may be or determine what CPU/NB GTL settings you should use?

Small FFT uses L1/L2 cache for calculations so its more likely to be CPU GTL Ref.
Large FFT uses DRAM so it crosses cross clocking boundaries of MCH/DRAM so it could be more likely DRAM Clock Skews or NB GTL Ref.

dont know how to prove it but i think.. so its just me here saying that. that the QX series is a bit of gloryfied urban legend. a qx6700 , a qx6800 and a qx6750 showing the same pattern. high volts and some how a wall at some stage that compare with the Q quivelant cpu.
On the other hand i think, they are much more robust and torelent to abuse.
as i said thats just me saying..

The new set up is based on the
PowerColor HD4870X2 2GB GDDR5


The EK-FC4870 X2 - Acetal CF

Technical data:
- dimensions of copper base: 206 x 118,5 x 7,5mm
- dimensions oftop: 207 x 119,5 x 8mm
- threads: 4 x G1/4
- fittings size: optional
- weight: 970 g

Iam going to use TFC 3/8 ID , 1/2" OD Compression Fitting


also testing if TFC 3/8" ID - 1/2" OD 45 Degree Rotary Compression Fitting - 1/4" BSPP High Flow

After about a month the block is here and last night i started with the removal of the original heatsink and the installation of the waterblock.
Few Ops! in the way, 1st spil some liquid on the card and the cabling, inside of the case when the reservoir tipped a bit.
Many hours later when the system was back in order, initial boot and monitor releaved high temps on the memory part on both GPUS around 102C meaning there is something wrong with the installation and tonight will taking it apart again and redo it.
