Hello,
I am new to overclocking and have a weird issue.
My mainboard is an MSI MS-7760. This board has 2x quad channel DDR3.
When I bought my pc, there was already 4x4 GB Corsair Vengeance DDR3 1600MHz 9-9-9-24 installed in one of the two quad channels.
Yesterday I bought an extra kit 4x4 GB to fill the second quad channel. The memory kit is exactly the same. So it is also 4x4 GB Corsair Vengeance 1600MHz 9-9-9-24.
Before I installed the new kit, my BIOS reports that the DRAM frequency was set to 1600MHz (like the sticker on RAM sticks report). After I installed the second quad channel kit, my mobo reports that overclocking failed and settings were reset to default. I noticed that the DRAM frequency was set back to 1333MHz. So I manually adjusted it back to 1600MHz and rebooted the PC. Immediately my mobo reports again that overclocking failed and cannot boot, so again settings were reset to default and now I am able to boot into Windows.
So my question is if anyone can tell me what the big difference is with 1 quad channel installed and 2 quad channels installed? All 8 memory sticks are equal, that is same manufacturer, same model, same speeds, same latencies and same size. Why am I unable to run the recommended DRAM frequency?
PS: CPU-Z reports 666.7MHz. This was higher before the installation.
On another forum I found out that default the sticks are running on 1.45V which is causing them to run 1333mhz max. However, I can nowhere find that voltage configuration in my BIOS (ClickBIOS II). But there is a X.M.P profile available which I can enable. When I do that, the BIOS applies a profile of 9-9-9-24 latency and 1600MHz @ 1.5V. Exactly what the stickers on the RAM sticks report! But sad enough after a reboot the mobo reports again that overclocking has failed and settings were reset to default...
