TCCD/BH-5 Memory??

[DigitalJ]

I've recently begun to delve into the fascinating world of overclocking, and I keep running into references about TCCD and BH-5 memory. However, when searching for dimms that are supposed to be top notch for overclockers (OCZ primarily), I don't see any references to these technologies in the specs.

Every time I google it, I just come up with links to retailers, usually in reference to Giel memory.

Does anyone know anything about these things and have the time to explain them to me? I'm completely in the dark as to how they affect overclocking performance, and which manufacturers include TCCD and/or BH-5 in their modules.

Thanks!!

Ahh, Winbond BH-5... that brings me back...

The terms you're referring to are just specific RAM chips that are known to be very overclockable and/or can reach ultra-low timings. Doing a Google search myself brought up some interesting info. I didn't know that Winbond's BH-5 chips were back in production. Very intriguing...

When shopping for RAM, it's important to note that most of the manufacturers of RAM modules just assemble the modules, they don't actually FAB the RAM chips themselves. Very few RAM chip makers actually exist, among them being Micron, Winbond, Samsung, and others. Companies like Geil and OCZ often buy RAM chips, then bin them according to a few parameters: inexpensive, overclockable, ultra-low latencies, etc. Then they assemble RAM modules with these RAM chips.

Both types of RAM manufacturers are very important! Both for the average user and for the OC'er. The RAM chips and the module they are mounted on need to be of good quality or the system will suffer from instability. By buying the super-expensive RAM, you get hand-picked RAM chips on high-quality PCB complete with heatspreaders and cool extras. It's a "you get what you pay for" sort of thing. Most people can get by on the inexpensive (but not cheap!) "value RAM" from Corsair or Kingston or Patriot or whatever. But if you want to run your system a bit faster, well... buy the expensive stuff. And if you're really into OC'ing, you'll have to pick your RAM chips and module type individually. It's a lot of work, but fun! :D

Interestingly enough, the link to RAM info I provided for bodman in his post, also has a link to TCCD ram at least. Samsung is often linked with TCCD, though I was under the impression that Samsung's memory market was sort of like Intel's GPU market....enormous, but in the background. I didn't know you could buy a samsung dimm. Turns out you can, sortof, but doing a "TCCD" search on their web site turned up nothing.

Guess I'll check with the DFI guys and see what they have to say.

Thanks, Saph.
