Hello! I've recently built up a real 'cookie cutter' rig as follows: MSI P67A GD55 B3 i5 2500k 8gb Corsair Vengeance RAM KFA2 560Ti Now the RAM is 1600mhz however when I go into CPU-Z it shows PC3-10700H (667mhz). In the BIOS I have it manually set to 1600mhz and XMP enabled, yet it continues to stay at 667mhz whereas it should be 800mhz... The BIOS is fully up to date, and the CPU is overclocked to 4.8ghz. Running on Windows 7 64bit. Any ideas why I can't get the RAM up to full speed? Cheers, Fish.
Where are you looking in CPUZ? Sounds like you're looking at the XMP tables rather than the actual speed. Take a look at the memory tab. Failing that, what does it report in the BIOS?
In CPU-Z the memory tab and the SPD tab both show 667mhz (667.1 in memory tab to be precise). The BIOS shows 'max bandwidth' as 1333, I cannot see an option to show you what it's actually running at.
The BIOS is set to run at 1333MHz then. You need to change it to 1600MHz yourself and manually set the timings.
You can't set it manually and enable XMP too. It'll override one of them. Disable XMP, and set it yourself. See what it does.
Yeh, just set the memory setting by hand. I have some motherboard ram combination, it won't detect the XMP profile itself. Also, some ram requires more voltage to be able to run at the XMP speeds. Though if you have tighter timings on slower frequency it is better this way.
