good evening

i am trying to get my system working with the above parts but when i run the memory at 1600 i get sometimes bsod.i try run them at 1333 but after some hours of working it cannot even boot and i have to clear cmos the system.

i have put manually 9 -9 -9 -24 and as i think i must put 1.60 thas is the dram voltage at the qpi dram voltage??

is there anything else that i have to do in order to run the memory stable at 1600? i have 6 x 2 gigas and all slots are occupied so maybe i have to change soimething else to make the system stable.thanxs for helping

Do you have the latest BIOS and did you laod setup defaults and enable XMP Profiles?

[Yellowbeard]

You have memory that is not officially rated to run at the voltage limit on a Core i7 IMC. Also, with 6 of them, you'll need to lower the memory frequency. Since you are not stable at 1333, try lowering it to 1066. If it is stable there, set the memory voltage to 1.65v, QPI voltage to 1.4v, and see if you can clock the memory back up from 1066. You probably won't get 1600 due to the voltage limits.

yes the latest bios.i haven't enable xmp profiles.does this memory is xmp capable?also the setting qpi/dram is the voltage of the dram right.it has it with only one option.qpi/dram

as i understand it will never play at 1600 due that i cannot give more than 1.7 volt to the memory.i just ask if i have to make any other change to the bios except the qpi/dram.

XMP for Core II / pre X-58 chipsets is probably not going to work on an X-58 MOBO. Also, XMP is probably not going to work with 6 modules. You are going to have to set the voltages manually, and clock your memory upwards manually, like I said above.

[DerekT]

My mistake. Those are not the correct modules for his platform.

Actually, there are 2 part numbers listed in this thread. I misread it at first also.

 

To the OP, which specific parts do you have? There is no such part as HX3X12G1600C9.

 

Did you buy this kit? http://www.corsair.com/_datasheets/HX3X12G1333C9.pdf

 

Or, did you buy 3x of these kits? http://www.corsairmemory.com/products/xms3dhx/default.aspx

 

Regardless, you still cannot use XMP. The settings I listed should work or be close to what you need to make these work.

Ah, I did not even know these were available yet. Sorry for the misunderstanding.

 

Essentially, the answer is still the same. You need extra voltage on the memory controller (QPIv) to run 6 modules. 1.6v for memory voltage and 1.4v+ for QPI should do it. Have you tried this yet?

I have the same setup as you described, I7 920, Asus Revolution and HX3X12G1600C9. My computer is running at 3.57 GHz and the memory is at 1700 MHz. The memory timing are factory 9-9-9-24 with 1.6 volts.

 

Here is what I did and I'm not saying it will work for you because every computer is different: I followed DerekT advice and downloaded memtest and every time I made change, I ran it. I started out with setting the AI overclock tuner in the Bios to XMP, ran memtest and it booted fine.

 

Then I changed the tuner to manual from XMP and ran memtest again. (Everything else is in auto)

 

My goal was to see how high it would clock without manually changing any voltages. Next I lowered the Dram Frequency to the lowest possible number, (I believe it was 800) raised the BCLK to 140 and ran memtest.

 

I kept increasing the BCLK by 5 and running memtest. It failed to post at 180 BCLK Frequency. As I was increasing the BCLK the memory would increase on it's own and had reached around 1363.

 

I backed the BCLK back down to 170 and increased the dram frequency manually to 1704 MHZ and all was well. It ran prime95 overnight without a glitch.

 

A couple of days later DerekT asked if I had the latest BIOS, because it allowed manually increasing the CPU ratio setting to 21 Which I promptly did and it survived a 12 hour Prime95 test without a stutter.

 

My Bios looks like this:

 

AI overclocking tuner: Manual

CPU Ratio setting: 21 (had to manually change from auto, but I did it last)

BCLK Frequency: 170

Dram Frequency: 1704 MHz

 

Everything else left on auto. Hyperthreading is on because this is a video editing work station. (But I did find out that if you turn it off temps drop on an average of 8 degrees C, so if you are a gamer you might want to look into disabling that) I also did this with an aftermarket cooler, I have no idea what the stock cooler is capable of so if that's what you have you may want to upgrade before attempting this. After a couple of days break-in, temps stay below 70C even on a 2 hour video render.

 

I am very happy with the Corsair memory and was pleasantly surprised that it overclocked so well. Hope this helps.

Good work David! :D:

 

And Kudos to ASUS for making the 21 multiplier fully parallel and native.

 

I have the same setup as you described, I7 920, Asus Revolution and HX3X12G1600C9. My computer is running at 3.57 GHz and the memory is at 1700.

 

First off you need to have the latest Bios, this allows you to manually enter the CPU Ratio setting to 21.

A couple of days later DerekT asked if I had the latest BIOS, because it allowed manually increasing the CPU ratio setting to 21. Which I promptly did and it survived a 12 hour Prime95 test without a stutter.

 

By Bios looks like this:

 

AI overclocking tuner: Manual

CPU Ratio setting: 21

Nice O.C. and thanks for taking the time to share your results.
