Asus Rampage Extreme Memory?

What is the best Corsair DDR3 2x2Gb solution for a Asus Rampage Extreme?

 

A common theme seems to be that mem-sticks are only stable at 1333 on the Rampage Extreme ... does Corsair have a dedicated / tested option for this mobo?

Thank you ... missed that. New question:

 

the site recommends

Enthusiast TW3X4G1600C9DHX

Overclocker TWIN3X4096-1600C7DHX

Extreme TW3X4G1800C8DF

 

But (alas) I ordered DHX TWIN3X4096-1600C7DHXIN, which seems to be an upgrade from TWIN3X4096-1600C7DHX ... e.g. " it's based upon Corsair’s high performance XMS3 DHX family of memory which includes Intel’s Extreme Memory Profiles (XMP)."

 

So since the Latency matches up for ea at 7-7-7-20 you would think I'm GTG, but halfcraft (in POST ID # = 373066 ...

Asus Rampage Extreme and TWIN3X4096-1600C7DHXIN) seems to be having problems going over 1333.

 

Thoughts advice for this n00b before I click all the parts in and play w/ bluescreens?

You should be fine, but keep in mind that you must overclock the CPU to make 1600Mhz on the DRAM. If you do not want to overclock, then go with two sticks of 1333Mhz DRAM. I advise you NOT to go with a four DRAM slot population as this can issue quite a few problems. You will notice that halfcraft has not responded after I posted his settings? Usually this shows that they are fine. You will need to customize your BIOS just as he did as well.

I'm going to configure my system with the same board and memory configuration with a different CPU (E8500). I'm curious as to whether your config worked well. I'm very close to placing my order for the parts.

 

Please let me know if it all worked well together.

 

thanks.

Halfcraft has a 400Mhz FSB (1600Mhz Quad Pumped) CPU, so he does not need to overclock to reach the 1600Mhz for the DRAM.

 

You will have to clock a 333Mhz FSB processor to 400Mhz to reach the 1600Mhz DRAM speed.

 

Very workable though.

Derek,

 

For this configuration, which slots should the RAM occupy on the Asus Rampage Extreme? I'm currently on slots 2 and 4 and got several errors while installing Windows XP 64 bit. Seems like files couldnt be copied correctly and I had to hit retry for it to work... Not sure why...

 

Thanks in advance.

I like the white slots. 2 & 4. I would drop the multiplier and lower the DRAM voltage first. Set the multiplier to 7 and the DRAM to 1.8v.

Download Memtest86+ V2.01 from--->

and extract the ISO image. Burn the ISO image to an CD-ROM disk.

Download CPU-z from
.

 

Run Memtest for two full passes. When assured of stable DRAM, then enter Windows and Run CPU-z and post screenshots of CPU-z's CPU, Memory and SPD tabs.

 

Results?

 

Here's where I am at the moment.

Yeah this is no good. I think the board is bad.

The sticks of ram work flawlessly in slots 2 and 4 on the Rampage Extreme AND the EVGA nForce 790i Ultra SLI. So the RAM is solid enough. I think my nforce board is stable too after i got this ram.

I think the board might be bad since I got constant blue screens on the Asus Rampage while installing Windows XP 64 bit and even after installing them.

Memtest passed for 3 passes on slots 2 and 4, failed on slots 1 and 3, i bet I need can only run these sticks only on slots 2 and 4.

 

I will most likely RMA the board. I can't believe that i'm having the opposite luck on this board compared to most people. Most people would have bet that the EVGA board would be broken and the ASUS should have been rock solid.

And more than anything else, i got a blue screen after i tried installing the audio drivers and the Creative XFI attachment.

 

Any assistance, at this point really needs to come from ASUS, but if anyone has anything to share, I'm listening.

 

--EDIT: any idea why on earth the board wouldn't completely shut itself down when I shut the PC off? one of the chassis fan was on even after i powered down the pc? I had to hold the power button down for several seconds before it compelely shut off. Im really not impressed. (although I think the throughput on my RAM was much higher on the ASUS while doing memtest, its just not stable enough)

 

Thanks.
