To overclock we attempted to use the bios frequency settings, but had better success by increasing the BCLK/PEG Frequency.
The best result we could achieve was 2812mhz with a 105.5 BCLK/PEG frequency setting. We reduced the Core Ratio limit via the 3770k to '45' to get as close as possible to our original clock speed of 4.8ghz. We didn't have to loosen any of the memory settings to achieve 2812mhz.
We managed to increase further to 2,920mhz but had to loosen the memory timings once we overclocked past 2812mhz, this had a negative impact on the performance results.
Increasing voltage past 1.65 didn't have any noticeable effect on the HyperX Predator 2,666mhz memory.
Validation at 2812mhz 11-14-14-30 is available over here.
We recorded a further reduction in rendering time with our 3D Studio Max 2011 scene render, improving by 3 seconds.
A noticeable increase over the reference 2,666mhz speeds, improving to almost 26GB/s of bandwidth.
Yet again, some noticeable increases in performance when the memory is running at 2812mhz. This are the highest scores we have achieved yet in this particular benchmark.
almost wet myself at those results. Any ideas when its out? I bought a Corsair H100 last month, what a cooler ! love it to death.
Very impressive kit. That said, 2,666mhz memory is still a little overpriced IMO. 2,400mhz is a lot cheaper and I wouldn’t think many people could notice the difference in the real world.
im waiting on 3,200mhz kits 🙂
you can get 16GB of slightly slower memory for 2,666mhz prices. Not for me, but interesting to read. I can see it being worthwhile in the pro industry for rendering.
@ Darth Digglers. No one needs 16GB of memory for gaming or even ordinary duties. id rather put the money into speed, not quanitity.
Good memory, shame they went for such huge heatspreaders, id have bought 16GB of it for my Z77 board, but id need to check my phanteks cooler I reckon before it would work right in the slots due to spacing.
