F3-16000CL9T-6GBTD + ASUS Rampage II Extreme BIOS

[GSKILL TECH]

This setting is to run DDR3-2000 F3-16000CL9T-6GBTD on the ASUS Rampage II Extreme motherboard. In this scenario, the Intel Core i7 920 is overclocked to 3.6GHz which is perfectly safe for this combination. You can also check the temperature in your BIOS to confirm that it is not overheating.

AI overclock - manual
OC from CPU level up - auto
OC from Memory level up - DDR3-2000
CPU Ratio setting - 18 for 3.6GHz
CPU Turbo Power Limit - disable

CPU configuration
CPU Ratio Setting - whichever you chose above
C1E Support - disable
Hardware prefetcher - enable

Intel C-STATE tech - disabled

BCLK frequency - 200

All others can be on AUTO

EPU II Phase Control - Full Phase

CPU voltage - 1.32V
CPU PLL voltage - 1.85V
QPI-DRAM voltage - 1.55V

IOH voltage - 1.35V
IOH PCIE voltage - 1.60V
ICH voltage- 1.20V
ICH PCIE voltage - 1.60V

DRAM Bus voltage 1.65V

CPU spread spectrum - disabled
PCIE spectrum - disabled
CPU clock skew - auto
IOH clock skew - auto

As a side note, this board is pretty nifty in that you can have different BIOS profiles saved. For example, if you have a setting for DDR3-2200 @ CAS 9 and DDR3-1700 @ CAS 6, you can save both complete settings of your BIOS and simply change back and forth when you want to instead of changing every single voltage and timing to operate at different speeds.

Settings for Asus Rampage gene II

I tried these settings with my Asus Rampage Gene II motherboard and the memory package I am using is
[ Perfect Storm] F3-16000CL8T-6GBPS
I set the timing as 8-8-8-21 and 1.65volts with all the settings you have above. It posted booted to windows and then Locked up. I used 18.0 CPU ratio so it was set at 3.6 GHZ. I am not using the stock cooler so overclocking temps should be just fine. I also have a question why is it you disable the HT technology? I am also emailing you guys as well, I thought maybe the forum would be an easier way to get information. Any help would be great.

Thanks,

Jeremy

QPI 1.5v is way too high ?can it destroy my cpu?

[GSKILL TECH]

kayawish24,

1.5V is no problem. It will not destroy your CPU. Seems like you have decent cooling, so it should not be a problem at all.

Thank you

hello....!

i cannot beleive this ! how can you say that QPI 1.5v is safe ? what you talking about.are talking about QPI or DRAM volts? and if you are talking about QPI volts then i think either intel or you are crazzy because according to intel cpecs QPI of 1.35v is the last safe for i7 CPU.now tell me to whom i shall trust?

Believe the stated official line is 1.35 for QPI and 1.65 for RAM....but with the OC you're showing 3.7GHz, 1.5 QPI isn't a problem. Intel is well known (and has been for years, for vastly understating the max voltage of most everything. I've seen i7 running at 1.7 and RAM at 1.85.

Sort of like the Intel spec on the i7 950 calls for 3.06 GHz yet you are running 3.7GHz you say.

G.Skill Tech,

I realize this thread is a bit dated, but I am hoping you might be able to answer a related question. I just bought this same motherboard and memory combination, but with the latest Intel i7 930 CPU. Is there anything you would suggest changing about these settings for the 930 versus the 920? I have this combination paired with tri-SLI Geforce GTX 280s with amazing results just at stock, so I am anxious to see what I can do with moderate overclocking (it's also water cooled with the Corsair H50). I have always been impressed with my benchmark results using your G.Skill memory.

Thanks!

[GSKILL TECH]

No different, same settings apply.

Thank you

G. Skill Tech,

As you suggested, I tried using the same settings with the 930 and the overclocking failed due to DRAM failures and it would not post (the R2E rolled back the changes on reboot). When I used all the same settings, I came out with 2005 Mhz for the DRAM and 4009 Mhz for the UCLK.In addition, the DRAM REF Cycle Time could not be set to 74, closest options were 72 (my choice) or 82. EPU II Phase Control is not an option in my BIOS revision (1704). You did not mention RAS# to RAS# delay, so I left it as auto.

Everything else was a match to your suggestions, but it was a no go for i7 930, so I assume there must be some adjustments necessary to compensate for the slightly higher clock speed. Please let me know your thoughts on different settings for the 930 as opposed to the 920.

Thanks!

SpeedRacer,

Simply leave them on default AUTO since the system will be able to configure them properly at that frequency.

pipes,

If you have cold boot problems, you will need to send the memory in for new replacements.

Thank you

I have change:
IOH Voltage - 1,15316
IOH PCIE Voltage - 1,51106
ICH Voltage - 1,12666
ICH PCIE Voltage - 1,51106

And this afternoon it has a good cold boot without problem, I have try with linx for 25 minutes and it'is stable.
I have a question, why two program of tree see my comand rate on 1T, cpu-z and cpu-tweaker, everest and my bios 3N? i have setting 3N on bios
thanks g.skill tech and all this costumer service
regards

It may be a glitch. Simply set BIOS to 1T.

Thank you

Thank you

If i set 1T to bios i can not boot with 2000 mhz of frequency

[GSKILL TECH]

Then you will need a minimum of 2.

I have see a test where a person make to go the ram with 1T without problem and without go over 1,65. maybe it's a controller integrate of my cpu?
