Rampage III Extreme+i7 930+Gskill pi Series=Headache! - Page 2

post #11 of 19

I do not think your RAM is limiting you - in other words...

 

 Integrated Memory Controller = IMC or "Uncore" [as seen in memory tab of CPU-Z]

 

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ This is your culprit! 

 

 The IMC's vary in ability and "quality". Specifically - in regards to latency. Latency is comprised of 2x parts.. your NB/Uncore speed and relative timings, as well as your RAM speed and relative timings. Raising Uncore speed.. raises bandwidth/throughput, while lowering timings can do both increase bandwidth and lower latency. That said... every IMC has different limits.

 

 You are starting to push your IMC latency hard with RAM speeds +2000mhz, as this requires NB/Uncore to be at a high speed as well. Uncore should always be 2x that of set RAM speed.. so if you are looking for 2200mhz RAM.. your NB/Uncore needs to be set to 4.4ghz in BIOS [by adjusting Uncore multi].

 

 To get the IMC to this speed.. you will need to focus on QPI voltage as well as IOH voltage. [1.42-1.46v QPI should be safe for watercooling.. though you may not need that much..again every IMC is different, you may get away with 1.36.. or you may find you need 1.5 as well] for IOH voltage.. I would set 1.22-1.26v ..lower once you have found stability.

 

 

**As well.. when you are pushing for more RAM speeds.. its a good idea to try to leave timings on Auto if you are having difficulties getting to POST.. see what the CPU likes on Auto.. make adjustments based on what you see is different from your previous settings.

Here goes:
Code:
* AI Over. Tuner - MANUAL
* OC from CPU Level UP - AUTO
* CPU Ratio set. - 22
* CPU Turbo Power Lim. - DISABLE
* BCLK - 182
* PCIE - 100
* DRAM - AUTO
* UCLK - AUTO
* QPI Link data Rate - AUTO
* Memory Recheck - DISABLE
* Memory Config. Protection - DISABLE
* CPU Diferential Amplitude - AUTO
* CPU Clock Skew - AUTO
* IOH Clock Skew - AUTO
* DIGI+ PWR Mode - X-POWER
* PWM Volt. Control - AUTO
* Load-line Calibration - AUTO
* CPU Voltage OCP - ENABLE
* CPU PWM Freq. - AUTO
* Extreme OV - ENABLE
* Extreme OC - AUTO
* CPU Voltage - 1.25
* CPU PLL Voltage - 1.88
* QPI/DRAM Core Voltage - 1.35
* DRAM Bus Voltage - 1.65
      - DRAM Ref. Volt. - AUTO
* IOH Voltage - 1.16 (AUTO)
* IOH PCIE Volt. 1.5 (AUTO)
* ICH Voltage - 1.11 (AUTO)
* ICH PCIe Voltage - AUTO
* QPI Volt. OCP - ENABLE
* IOH Volt. OCP - ENABLE
* DRAm Volt OCP - ENABLE
* QPI PWM Freq. - AUTO
* IOH PWM Freq. - AUTO
* DRAM PWM Freq - AUTO
* CPU Spread Spectrum - DISABLE
* PCIe Spread Spectrum - DISABLE

With this config, I got 4004Mhz on CPU and 1459Mhz on RAM totaly stable...

That looks good.. 

 

couple things though:

 

you need to be manually setting the QPI, Uclk and DRAM multipliers manually to make sure you know what speeds your running here, and not relying on mobo to pick for you. If you chose a higher RAM multi.. you would be around 1950mhz memory now, instead of 1400mhz.

 

*which btw- 1459mhz RAM as you are saying.. is only 724.9mhz ... about 500mhz slower than the 2200 you are looking to attempt. 

 

 

Going forward.. i would use the above settings as a test-bed.. load them and just set DRAM multi higher.. so you are running faster memory only.. then test. If you pass, bump bclk 5mhz and retest. When you hit a failed stress test, just look at CPU speed... if you know it can run stable with the supplied vcore, then look to add QPI/DRAM core voltage to bring stability. My guess is that you will be pushing higher than 1.38v for QPI/DRAM core volts to get near 2000mhz memory.

 

*also.. please set Uclk multi to 18x and DRAM multi to 8x.. you may need to raise IOH to 1.2v

How do I change these multipliers? I can not find a specific option for that ...

should just be able to toggle multi by goin to the option and using + or - keys..

The only one option with "multiplier" in my BIOS is "CPU Ratio set". No other option I can change the multipliers of these items ... And, I aways choose UCLK = 2 x DRAM freq.

In BIOS if you tab down to DRAM and press enter a box should pop up that lists different freq, tab to the one you want and press enter. Same thing for UCLK and QPI Link.

* DRAM - AUTO
* UCLK - AUTO
* QPI Link data Rate - AUTO

This link will show you the relationship between BCLK and the three above freqs.

With Asus boards you do not pick a multiplier, you pick a frequency.

Well, nothing again ... Idahosurge, thanks for the tips!

What do I need to get a change to at least 4Ghz on CPU and RAM to at least 2000MHz? CPU with free multiplier , for example, help in something?

you need to hit +200bclk.. that is all.. voltages and cooling go with that of course.
