For the record....
There are NO voltage regulators in DDR chips or on sticks of DDR memory.
Not on/in CH-5 and not on/in TCCD. Whoever/whereever that stuff comes from is mis-informed, period.
Looks like the latest revisions of the TCCD chips are showing the expected signs of manufacturing improvements that always follows the excellent ongoing work of high quality manufacturers, ever improving thier yeilds and efficiencies. Samsung has always been such a company.
The chips....just like BH-5....have an absolute maximum rating of 3.6V. It would seem these newer chips remain stable with higher operating voltage than older TCCD's and we get to enjoy the speed benefits of running the chips at higher voltages. Older versions probably got toohot at some point inside at higher voltages and instability prevented reliable operation, the newer chips have a higher STABLE maximum performance point.
I cant read the labels well enough in the pictures to see the date-code, but there is most likely a date, after which, you get the higher max performance available.
I for one would luv to see the best someone can get out of 4x 512M of these newer versions in a 939 board ...aka 2 GIGs... as this is my goal for a 939 future, 2 GIGs. 250Mhz x11 with 4x 512M TCCD @tight on a 3200+ 90um 939chip would be really cool.
To repeat.... there are NO VOLTAGE REGULATORS in DDR chips. None, period.
I dont give awho told you, or what engineer buddy said what, etc... they are ALL full of it. The chips are made by the BAZILLIONS in Samsung's factory and shipped out to everyone. There are NO custom anythings being made, and I really hate to burst your bubbles but Mushkin/OCZ/etc/etc amount to SQUAT for volume as customers of Samsung. They ship MILLIONS of these chips per month and the "specialty" ram suppliers (the folks like Mushkin that solder them onto PCboards) dont make a DENT in Samsungs production.
Anyone of YOU can go into the DDR stick making business at the drop of a hat, all it takes is a few $K to get started. There are a ton of Taiwanese contractors that make generic "reference" DDR pcboards, there are zillions of contract manufacturing houses that will take your components (chips, resistors, caps, pcboard, spd-rom) and solder them together for you. You then test and ship and support.
It is NOT rocket science. Nobody is building in special super-duper circuits for mad-speed boosts, etc. What the Mushkins/OCZ's/ etc do is put in the extra effort to SUPPORT us OCr's and our efforts, and they do a great job, and we all thank them very much. Its not a big margin business and they take alot of crap in the process, so thanks guys.
The "EDGE" you can get is in quality components....resister packs and caps with good tolerence's meeting the DDR spec correctly, good quality pcboard materials, and like in the case of the "brainpower" boards a little better layout of components to increase high FSB performance. Thats about it. Hell, we dont even see any of the OEMs bothering to employ "better" serious cooling to differentiate themselves from competitors. As has been discussed in this thread, a heatspredder with more BULK using perhaps copper and mated to the DDR chips with a really GOOD heat transfer medium would be a major point of differentiation....assuming everyone uses the same TCCD chips.
Just keep in mind how many units of DDR all the specialty makers ship in a month VERSUS one months production at...DELL? HP? etc. It pales in comparison.

Your tips are welcome, but I doubt anything will work. PS, I tried to boot into windows again at 2.5-3-3-7 1T at 240mhz and it kept looping post. I running 240mhz at 3-3-3-7 1T as I'm typing this.
