Corsair Employees RAM GUY Posted October 8, 2007 Corsair Employees Share Posted October 8, 2007 With 4 modules I would suggest DDR667 and set the memory Voltage to 2.0 Volts. But we have tested this MB with 4 6400 Modules at 800 MHz with an 1066 FSB CPU, with these settings: SLi ready: Disabled Memory Voltage: 2.0v NB Core Voltage: 1.4v TCL: 5 TRCD: 5 TRP: 5 TRAS: 15 Command Per Clock: 2 TRC: 28 In addition there is a patch you will need to install for Windows Vista for more than 3 Gig of memory.

Corsair Employees RAM GUY Posted October 9, 2007 Corsair Employees Share Posted October 9, 2007 There is an option to remap the memory that you may have to set for it to see all 4 Gig and you need the 64-Bit version of the O.S. Link to comment Share on other sites More sharing options...

Yellowbeard Posted October 10, 2007 Share Posted October 10, 2007 nothing in the manual still waiting to hear from asus manual mentioned ecc but ram i have is non ecc looks as if in the next few days both ram and mb will have to be rma :( Try a single stick and boot the system with it in each memory slot to see if you have a bad slot on the MOBO.

Jumms Posted October 20, 2007 Share Posted October 20, 2007 I am having the same issue. I am running a striker extreme mobo with vista 32bit. I have 4x Corsair CM2x1024-6400 800MHz sticks. When I put 3 of them into the slots, computer boots up just fine. But when I put in the 4th stick, all I get when I start up the computer is a solid beeping sound. I was reading in some other forums in here and saw that I needed to download a vista update to be able to read the 4th stick which I did but after installing it and installing all 4 sticks, it booted up but the bios was only reading 3 of the 4 sticks. Am I doing something wrong or is the constant sound of the mobo telling me the something is broke? Thanks for the help guys. Link to comment Share on other sites More sharing options...
Yellowbeard Posted October 20, 2007 Share Posted October 20, 2007 If you have a 32 bit version of Vista, you will not be able to fully utilize 4gb of memory. The patch cannot change this. You need a 64bit OS to fully utilize the 4gb of system memory. Link to comment Share on other sites More sharing options...
Jumms Posted October 20, 2007 Share Posted October 20, 2007 Sorry I forgot to mention the fact that I know I won't get all 4Gb out of it. I'm just curious why the bios won't even read the 4th stick. Link to comment Share on other sites More sharing options...
b1z Posted October 20, 2007 Share Posted October 20, 2007 I'm not really a Windows user, but to give you a way to understand this... Read this, perhaps it helps - Though, I don't know how Windows handles memory.

damon_dusk Posted October 21, 2007 Share Posted October 21, 2007 Sorry I forgot to mention the fact that I know I won't get all 4Gb out of it. I'm just curious why the bios won't even read the 4th stick. I'm curious with JUMMS =) I'm running (4) 1GB sticks of 6400 on a Striker Extreme with Vista Home Basic 32-bit and my BIOS posts all 4 gigs of RAM and PC Probe sees all 4 DIMMs even though Windows cannot. That leaves me curious as to why so many people are having the 4th stick not post..... My memory voltage, in case anyone wants to try it, is 2.100v. No overclocks anywhere in the system.

Corsair Employees RAM GUY Posted October 22, 2007 Corsair Employees Share Posted October 22, 2007 Did you test the modules one set at a time? Do they all pass one module and or one set at a time? Did you find the option in the BIOS to remap the memory? (Might be listed as (OS Select for DRAM) Link to comment Share on other sites More sharing options...
Jumms Posted October 22, 2007 Share Posted October 22, 2007 I just tested all the indiviual sticks in all the different slots one at a time, and then in pairs. All sticks are working and all slots are working. Then I started putting them in 1 stick at a time and it worked all the way up till the fourth stick which again wasn't being read by the bios. I'm now gonna look for this remap memory setting. ...I just found the OS Select for DRAM setting and it was set to Non-OS2. Just to check and make sure it would do the same thing the other way, I changed the setting to OS2 and rebooted. When it restarted, the BIOS was still only reading 3072MB on RAM installed and 3071MB usable. I then reset the setting back to Non-OS2. Also, all the overclocking setting are set to auto and all the voltages are also set to auto. As of right now, I don't have the Vista update installed nor have I updated the BIOS if that matters at all. Any ideas? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 23, 2007 Corsair Employees Share Posted October 23, 2007 You should contact the MB maker if all of the modules are working one up. And if you change the setting to remap the memory you would need to reload the O.S. but I would use http://www.memtest.org to test the system to make sure they are all being detected.
