Warning New Twinmos TMII400 dual packs not UTT anymore

[Reefa_Madness]

The question was asked by tictac above, but never answered...what is the parts number on the paper sticker of the non-speed premiums TM that you just received?

If they are not UTT then it is important to know the part# so as to be able to add it to the "knowledge base" of what modules to avoid (do not have UTT).

And if you don't mind...what are the rest of the codes on the chips (five digits on the date line and those on the last line). Are they TwimMOS or M.tec labeled?

This information is consistent with the following post by The Stilt in this thread (post #15).

Twinmos probably noticed the value of UTT chips, and stopped using them in their "vanilla" sticks. I haven´t seen a single "vanilla" (non speed premium) stick that have UTT chips on them made after week 05 of 2005.

I spotted some interesting looking chips from 1GB kit of CL3 ValueRam...
Those chips have similar two dots like Winbond chips, but the two metal pieces on the each two sides of the chip are more narrow than in Winbond chips. Tried these on ol´ good IC7 motherboard, and they ran flawless at 210MHz with 2-3-2-5 latencies (2.6V). I think that Infineon did something to these chips, because they can do CL3 unlike normal Winbond chips.

Raising VDD didn´t help with latencies, so this is basically old CH-5 chip made by Infineon. Order code for the chip is HYB25D256160CT-5.

These chips come on ValueRam sticks relabeled as D3208DLCT-5A
