When it came to testing the maximum overclock we gave the memory modules a maximum of 2.8 volts and we then proceeded to find what they could do at the most aggressive timings with trial and error. All speeds are their maximum stable overclock.
One thing definitely worth noting is that none of the modules are actual Dual Channel modules and it is quite well known that when running modules in Dual Channel the maximum overclock is hindered since there is more of chance of an error occurring due to ensuring not one, but two sticks can reached your desired speed.
- Crucial PC3200
Crucial was capable of taking the lead in overclocking which was very surprising considering that their memory is rated at the very high CAS latency 3. Considering that we tested all the memory at CAS 2 it was quite shocking to see that not only did it overclock by a few MHz but by the most at a very high 232MHz FSB.
- Mushkin PC3200
While Mushkin were capable of pulling out the most number one spots at DDR-400 in our benchmarks it was interesting to find that it was only able to achieve a maximum stable overclock of 216MHz FSB. Saying this, it far from makes the module bad since most people will simply be running it at the stock DDR-400 speeds which we see it is highly capable of doing very well.
- Kingmax PC3200
Kingmax was also only to achieve a smaller overclock of 218MHz FSB and like the Mushkin was taking number one spot in a lot of the tests at DDR-400. Since these modules are of better quality it will be interesting to see how they perform even when they are clocked lower than their competitors.
- TwinMOS PC3200
TwinMOS was only able to get one MHz up on the Kingmax achieving 219MHz FSB.
- Buffalo PC3700
Buffalo were able to achieve a maximum overclock of 229MHz FSB which is only slightly behind the Crucial module but it is definitely worth taking note that these are 512 Meg modules compared to the 256 Meg modules used with Crucial. Buffalo have been able to create quite a nice overclocking stick using the Winbond BH-5 chips.
- Corsair PC3500
Corsair was capable of getting a maximum 223MHz FSB stable overclock which was slightly lower then the Buffalo modules which use the same chip. We will see what this means when it comes to actually performance as Corsair were up the top with Mushkin and Kingmax who aren't able to overclock as well.
