help overclocking DDR3 RAM
The amount a 1600MHz RAM can be overclocked depends on various factors. Currently, your setup seems stable with the given configuration: DRAM Frequency at 980.1 MHz, FSB at 4x speed, tRC 39, voltage 1.64V, and XMP set to 9-9-9-24. You're considering lowering timings or continuing to increase FSB for further gains. Please decide whether to adjust timings or stick with the current approach.
Should support DDR3-2133 at around 1066MHz with voltages of 10-12-12-30 or 10-11-11 at 1.65V
For 980MHz it should work with 9-11-10-28 or 10-11-10-30 at the same voltage
XMP settings are saved in RAM and can be chosen in the BIOS for simple overclocking. Just load the XMP profile and all parameters will be configured. I wouldn't go into timing details, as the improvements might be negligible compared to the work involved. Base clock overclocking affects XMP timings, so consider CPU multiplier overclocking instead if possible.
Hello... Could you share your CPU/MB/system information as well? The setup includes a 990FXA-GD65v2 board, FX-6300 CPU (245x19.5), and a GTX 960 from EVGA. PSU is 750w, and EVGA is also included.

Increasing the base clock will affect XMP settings, so consider CPU multiplier overclocking if possible.
Edit: Are you working with an LGA775 board?
I believe the CPU is already at its maximum capacity. I could push it a bit more, but it wouldn’t be worth it—requiring extremely high voltages (over 1.5V+) would be risky and likely unsustainable. Some sources suggest around 1.55V as the upper limit, but I’m hesitant to reach that just for a modest speed boost of about 120MHz. It performs well at 1.48V, which is already quite high.
I’d still like to try further FSB overclocking, though temperatures spiked significantly only at 220MHz, so I ended up installing a new heatsink, an MX-4 cooler, and a small fan.
Oh, and I’m not doing this on a 775 board—I’m using a 990FX. But honestly, the 775 was much better for FSB overclocking. I recall getting one up to 300 MHz without a fan, which was a long time ago; things have changed a lot.
Support should cover DDR3-2133 at around 1066MHz with voltages of 10-12-12-30 or 10-11-11 at 1.65V. For 980MHz it should work at 9-11-10-28 or 10-11-10-30 at the same voltage. Thanks, I'll test 2133 or nearer.
