P55 vs X58 Memory Performance Analysis w/ OCZ Platinum Series - Overclocking

While here we would tend to overclock the kit normally, we won't today due to the focus of the article. In saying that, we'll leave the same header because we'll really be talking about what we always do on the overclocking page.


As you can see below on our P55 Deluxe motherboard from ASRock, we had no trouble getting the default 1600MHz with the 7-7-7-24 setup. To get this we used a 200 BCLK along with a 2:8 memory divider.




You can see the validation here.


Due to fairness sake, we moved the memory on our GIGABYTE EX58-UD5 to 7-7-7-24 at the same 1600MHz clock. Considering these timings are slightly more relaxed than the standard 6-6-6-24 setup, it comes as no surprise that there wasn't an issue.




You can see the validation here.


The CPU speed was something that we had to worry about. Our i7 920 uses a 20x multplier while our i7 860 uses a 21x. To keep the CPUs together in speed and again for fairness sake, we dropped the i7 860 multiplier to 20x and with both CPUs running a 200 BCLK we're at 4GHz or there about as the screenshots show.


Important Editor Note: Our maximum overclocking result is the best result we managed in our limited time of testing the memory. Due to time constraints we weren't able to tweak the motherboard to the absolute maximum and find the highest possible FSB, as this could take days to find properly. We do however spend at least a few hours overclocking every motherboard to try and find the highest possible overclock in that time frame. You may or may not be able to overclock higher if you spend more time tweaking, or as new BIOS updates are released. "Burn-in" time might also come into play if you believe in that.
