Overclocking PNY's XLR8 Memory

Overclocking Results:
4-4-4-12 5-5-5-15
memory speed:

1120 MHz

1220 MHz

If you're new to Overclocking and not sure what to do, check out these two excellent Guides for some pointers:
Overclocking the CPU and Memory
Overclocking the Videocard

Before PCSTATS will overclock the PNY XLR8 D22GX85XL-5 for your reading pleasure, we first nned to adjust the memory to run at (tighter) 4-4-4-12 CAS latency timings. The PNY XLR8 D22GX85XL-5 did not have any issues with this, so we'll see how high we can overclock with these timings first.

Starting from 800 MHz, the PNY XLR8 D22GX85XL-5 memory clock speed was increased 20MHz at a time.

At 960 MHz the PNY memory started to give us problems so the DDR2 voltage was increased from 1.8V to 2.0V. That stabilized things and allowed the PNY XLR8 D22GX85XL-5 modules to overclock further. PNY's XLR8 RAM gave us some more problems at 1040 MHz, so power was increased to 2.1V.

The maximum speed the PNY XLR8 D22GX85XL-5 memory was operate at with tight 4-4-4-12 timings was 1120 MHz (with 2.2V). Compared to PNY's other memory kit, that's not bad at all.

PCSTATS next loosening the memory timings back down to 5-5-5-15 (stock), and started overclocking from 1120 MHz with 2.2V. At 1200 MHz the PNY XLR8 D22GX85XL-5 memory required a bit more voltage, so that was increased to 2.3V.

The fun quickly ended, and PNY's XLR8 D22GX85XL-5 fizzled out at a maximum speed of 1220 MHz (with 5-5-5-15 timings and 2.3V). The memory was fairly warm by this point, and overclocking any further seriously affected stability.

Increasing DDR-2 memory voltage did not allow the memory to reach any higher speeds.
