Super Talent 2GB PC2-6400 T800UX2GC4

I quickly found out that this memory is addictive. I found myself spending near the entire weekend overclocking it, trying to push it further and further. I don’t usually become such a frantic overclocker, but these modules dragged me in. First off, it was evident that these modules loved any voltage you could throw at them. At stock speeds with 2.3v, 3-3-3-8 was completely possible and 100% stable after a 4 hour MemTest run.

You’ll notice that I have more successful overclocks than in other memory reviews, but that’s because as I was tweaking the timings, I didn’t expect each setting to be completely stable. I will only use 8 of the below settings in our graphs, although all settings went through complete testing.

Successful Overclocks (* Modules did not pass MemTest error free.)
• 400MHz, FSB200, 4-4-3-8, 1.8v, 2.8GHz
• 400MHz, FSB200, 4-3-3-8, 2.3v, 2.8GHz
• 400MHz, FSB200, 3-3-3-8, 2.4v, 2.8GHz
• 400MHz, FSB240, 4-4-3-8, 1.8v, 3.37GHz
• 400MHz, FSB240, 4-3-3-8, 2.3v, 3.37GHz
• 400MHz, FSB240, 3-3-3-8, 2.4v, 3.37GHz
• 445MHz, FSB267, 4-4-4-8, 2.2v, 3.7GHz
• 467MHz, FSB280, 4-4-4-8, 2.4v, 3.92GHz
• 500MHz, FSB250, 4-4-4-8, 2.2v, 3.5GHz
• 520MHz, FSB260, 5-5-5-12, 2.4v, 3.65GHz
• * 530MHz, FSB265, 5-5-5-12, 2.4v, 3.7GHz
• * 540MHz, FSB270, 5-5-5-12, 2.4v, 3.79GHz

I was told to expect DDR2-1000 to be possible, with 5-5-5-15 timings. As you can see, that was blown away also, because DDR2-1000 was again 100% stable with 4-4-4-8 timings with only 2.2v. Last month, I took a look at Corsairs PC2-6400 kit, which could also mimic those settings, but I couldn’t push it over DDR2-1000 speeds and remain completely stable. I was able to bring these modules all the way up to DDR2-1080 speeds, but with the lax timings of 5-5-5-12. Note that DDR2-1060 and DDR2-1080 speeds were not completely error free in a Windows MemTest run, however DDR2-1040 was.

The ASUS P5WD2-E Premium only goes up to 2.4v and I am not sure if any VDIMM mod currently exists. If you have a motherboard that can go beyond 2.4v, I fully believe that this memory can be pushed even further than I was able to push it. I could see the last two above settings be perfectly stable with 2.6v, if you dare go that high. Don’t quote me, but I can see it be completely possible because this memory *loves* voltage.
