I am hoping to get some technical support regarding an issue with the motherboard and RAM in my new pc:<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p>
<o:p></o:p>
RAM: OCZ 6G(3x2G) DDR3 Reaper 2000Mhz (PN - OCZ3RPR2000LV4GK)<o:p></o:p>
CPU: Intel Core i7 960 Processor LGA1366 3.2GHz<o:p></o:p>
Motherboard: Gigabyte GA-X58A-UD7 LGA1366 X58 6DDR3<o:p></o:p>
BIOS: Version: F7<o:p></o:p>
GPU: Asus EAH5970 2GB GDDR5<o:p></o:p>
OS: Microsoft Windows 7 Home Premium 64bit<o:p></o:p>
<o:p></o:p>
<o:p></o:p>
The following has been an ongoing issue for all the BIOS versions I have tried (F6, F7w and F7).<o:p></o:p>
<o:p></o:p>
Ever since the first installation I have been unable to get the BIOS to recognise all 6 GB of RAM being used in triple channel slots. This is reflected in the BIOS start-up screen and Windows 7 (6GB recognised, only 4GB useable). I have verified in another machine that all the RAM sticks are functioning correctly. Indeed all 6 GB gets recognised if I slot the RAM sticks into a non triple channel slot combination.<o:p></o:p>
<o:p></o:p>
After reading some forums I tried specifically setting the RAM BIOS settings for each channel to CL 9-9-9-30 (CAS-TRCD-TRP-TRAS) (as per the OCZ website) with a voltage of 1.64V (the BIOS does not have the option to select 1.65V as recommended by the OCZ website). <o:p></o:p>
<o:p></o:p>
to get the RAM to run at 1600Mhz instead of 1066Mhz (BIOS auto setting), again none of the BIOS multiplier options allow me to select the setting to run the RAM at 2000Mhz.<o:p></o:p>
Other multiplier settings:<o:p></o:p>
x8 = 1066Mhz<o:p></o:p>
x10 = 1333Mhz<o:p></o:p>
x12 = 1600Mhz<o:p></o:p>
x14 = 1867Mhz<o:p></o:p>
x16 = 2133Mhz<o:p></o:p>
x18 = 2400Mhz<o:p></o:p>
<o:p></o:p>
At the moment (for BIOS version F7) the PC also undergoes a reboot loop with the message , rebooting 3-7 times, then eventually loading Windows 7 successfully, but still only recognising 4GB out of the 6GB RAM.<o:p></o:p>
<o:p></o:p>
My question:<o:p></o:p>
Are there any other specific BIOS settings I should be using to: <o:p></o:p>
1. Get the BIOS to recognise all 6 GB of RAM in triple channel mode and;<o:p></o:p>
2. To run the RAM at 2000Mhz<o:p></o:p>
<o:p></o:p>
I have looked everyone and cant find any example of setting with this particular RAM brand / model. Any help / suggestions you can provide is appreciated.
