ASUS A8N32-SLI Overclocking with Corsair and OCZ

The Memory


- Corsair XMS-3500LL PRO


A brief rundown


Looks wise the latest Corsair memory is no different from the other modules that sit in the PRO line up. The LED activity lights found on the top of the module, while cool looking, aren't all that useful to most people but still it's a unique selling feature which may well convince people to go with Corsair over another brand while looking in computer stores.



Corsair and ASUS have worked together to make this module the "Must Have" item for users of the A8N32-SLI Deluxe motherboard. The kit consists of 2 x 1GB modules that utilize an aggressive setup of 433MHz (PC3500) with the timing set at 2-3-2-6 which some people might not think is the best but as soon as we add the fact that these also support 1T at this speed, the modules are excellent for mild overclockers.

The general rule of thumb is that 1GB modules will not overclock as well as 512MB modules. When it comes to overclocking memory you can be there for literally weeks trying to find exactly the right settings, so when it came to overclocking these modules we used the stock timings of the OCZ PC3700 Gold Edition Rev 3 modules as a guide.


Utilizing the timings 2.5-3-3-8 with the 2T command rate we were able to achieve a maximum of 257MHz (or 514MHz DDR) @ 2.8V. The stock speed on these modules are 218MHz so an increase to 257MHz is fantastic and there is no doubt in our heads that there is a little bit more head room there, especially if you want to spend hours and hours tinkering for the highest overclock.


- OCZ PC3700 Gold Edition Rev 3


A brief rundown


The OCZ are the more astatically pleasing model as there is no denying they are one set of sexy looking modules. There isn't a lot to say about the OCZ memory, it doesn't have any fancy LEDs on it and it hasn't partnered with anybody making it a lethal combination with a particular motherboard. They are just a set of cool looking high speed modules.



The OCZ memory comes at a higher clocked 466MHz but does come at the cost of timings. While Corsair uses the very aggressive 2-3-2-6 timings at 433MHz, OCZ relax them out to 2.5-3-3-8 to achieve the higher front side bus.


Overclocking the OCZ PC3700 Gold Edition Rev 3


When it came to overclocking we didn't have to adjust the timings because we wanted to find what the maximum front side bus was at these timings against the Corsair memory.


We really did expect them to perform a fair bit better then the Corsair because the OCZ sticks are rated 33MHz DDR higher at stock speeds then the Corsair and while we didn't think this would all carry over to the maximum overclock, we did expect a bit more then the 6MHz DDR (higher than the Corsair memory) which we did get.


The OCZ PC3700 modules a maximum overclock of 263MHz FSB or 526MHz DDR. This is a nice 30MHz increase from the standard 233MHz. While this isn't as major increase, it is a healthy one none the less.
