Patriot PDC32G1866LLK PC3-15000 2GB DDR3 Kit
With DDR3 speeds ramping up on an almost weekly basis, It's extremely difficult to obtain two or more memory kits with similar specifications to perform any kind of worthwhile comparison. Therefore, the Patriot PC3-15000 kit will be placed up against the recently reviewed OCZ Platinum PC3-12800 kit with it's stock frequency, latencies and voltage changed to match the Patriot kit.

Test Settings & Overclocking
It is an unfortunate fact that many memory kits tested here at Overclock3D fall at the first hurdle by not being able to run with 100% stability at their advertised stock settings. Therefore the first test for the Patriot PDC32G1866LLK kit was to test their ability to run at 933mhz with 8-8-8-24 timings on 1.9v.
On first installing the modules and manually setting the timings and frequencies on our P5K3 testbed, Windows constantly bluescreened during bootup. Remembering some of the settings used to stabilise the previously reviewed OCZ Platinum DDR3 kit, we switched the modules into DIMM slots A2 and B2 on the board and set the "Relax Level" to 3 in the BIOS.
This time the modules successfully booted into Windows, but on attempting to run any memory intensive benchmarks, the system once again blue screened. Not deterred by this, we switched out the Asus P5K motherboard for an Asus Blitz followed by an Asus Maximus - neither of which could add any further level of stability to the modules.
Finally, we changed back to the P5K3 motherboard and loosened several memory subtimings along with running the modules at a lower-than-rated 1.85v. This added enough stability for us to complete all benchmark tests without any errors but was far from ideal for any kind of 24/7 usage.
Needless to say that Overclocking was totally out of the question, but in the interest of completeness here's how they faired against the OCZ Platinum kit:
