Mushkin 6GB (3x2GB) XP series DDR3 PC3-12800 1600MHz Kit
For today's testing we will be using the Gigabyte EX-58 UD5, a mid-range Core i7 motherboard from Gigabyte that will allow us to push the memory on test to its absolute limit. Here's a breakdown of the rest of the components:
Intel Core i7 920 'Nehalem' @ 2.66Ghz
Mushkin 6GB (3x2GB) XP series DDR3 PC3-12800 1600MHz Kit 7-8-7-20
Patriot 6GB DDR3 PC3-12800 1600MHz Viper Series Low Latency Kit 8-8-8-24
Corsair CL8 1600MHz 8-8-8-24 3x2GB kit
Gigabyte Odin 1200w
Windows Vista Ultimate 64bit SP1 + Updates
- Lavalys Everest 4.10
- SuperPI mod_1.5
- Sisoft Sandra 2009
- 3DMark Vantage
- Far Cry 2
For the run of benchmarks, we will be comparing the Mushkin 1600MHz 6GB Patriot kit to the1600MHz 6GB Patriot Viper and Corsair Dominator kit.
I had better success in raising the frequency despite my initial disappoint of the kit not pushing any higher with the stock latencies. Even dropping the latencies to 8-8-8-24 resulted in a very mild overclock topping out at 1712MHz. Dropping the Latency to CAS9 gave a small increase again to 1800MHz so we decided to go for broke and slackened the timings right back to 10-10-10-27 and this is where the memory seemed to come alive, breaking 2100MHz! Any higher and we encountered various forms of instability and not wanting to corrupt yet another Vista install I decided 2100MHz was plenty to show the Mushkins performance possibilities. No doubt with higher voltages, the timings could be tightened but with the risk of damaging the modules and the memory controller.
