On Monday, I requested to RMA my board with mWave. This morning, I headed out to their facility to make the exchange for a new board with high hopes of being able to attain more satisfactory clocks for my memory.
Blah, blah, blah. Some more blah, blah, blah. Five minutes later, the CSR returns to the front counter with four boxes. He gives me his blessing to inspect each unit, pull off the NB HSF, and make a decision as to which one I would like to keep. The first two HSFs I pulled off revealed the same exact code as the one I was returning (0440A2 TAIWAN). The third unit displayed 0439A2 TAIWAN under the HSF. At this point, I'm loosing hope because I have already subscibed to the belief that a KOREA chip will outperform a TAIWAN chip despite the fact that there is no solid proof regarding this matter. Box #4 is a keeper coded with 0442A2 KOREA on the chip. I drive back to La Habra for one hour of testing before I head off to work.
0440A2 TAIWAN
Highest Memory Frequency: 270MHz @ 2.5-3-3-10
Memory Modules Tested: 2x256MB G.Skill TCCD @ 2.8V
Stability - Over 12 hours of Prime95, over 100 loops of Memtest Test #5, and Super Pi 32M. Windows will not boot at 280MHz or above with these timings.
0442A2 KOREA
Highest Memory Frequency: 285MHz @ 2.5-3-3-10
Memory Modules Tested: 2x256MB G.Skill TCCD @ 2.8V
Stability - Over 25 loops of Memtest Test #5 and Super Pi 32M. Windows will not boot at 300MHz or above with these timings.
Keep in mind I only had approximately 90 minutes to install and conduct my testing. Because I was able to pass Super Pi 32M without incident, I started up Prime95 Torture Test/Blend/Priority10 just before I left for work.
Well, folks. I still haven't come across any technical documentation that proves the superiority of the Korean chips over the ones made in Taiwan. All we have is speculation. What I do know for sure is that I have a Korean chip manufactured 2 weeks later than my last one and it allows me to hit DDR570 as of this writing. Draw your own conclusions as I have already come to mine. ;)
