I know that SP's are BH5's but I'm not sure if those are 
They might be.

What is the information that is on the paper stickers...that will help identify the chips.
Also, above the code that you posted is a five-digit date code, which ends in either a letter or digit. If you will post both of those bits of info, maybe we can identify the chips used.
The other clue, if it is Winbond UTT are physical markings. The chips will have the two trademark Winbond "dimples" on either side of those codes above and it will have a small hole in the lower left hand corner and on each edge (left and right) of the IC there will be two metal strips/staples visible. If you have these markings, then you are almost assured of having Winbond chips.

Yea see how they respond to slightly higher Vdimm but active cool them just in case. You can usually tell which chip it is by how well it responds to certain timings and voltages.

If that list is correct, it lists the chip as being a PowerChip part. There are no pics, however, with which to confirm the identity.

AADT is PowerChip.
Date ending in "D" is PowerChip.
Chip in the pic is made 2004/06. No UTT or any other Winbond ddr-ram was in production that point of time.

I know that the "D" designation is a PowerChip part for the Speed Premiums, but I wasn't sure if the M.tec labeled "value ram" was using the same coding scheme as the "parent" label, TwinMOS.
The pics of the PowerChip ICs used in the Speed Premiums review per the attached link do not resemble the ICs in the pics posted above. The SP chips have the small single hole in the lower corner that those pictured above do not have.
That is why I made the comment that there are no pics with which to confirm that those modules above are using the PowerChip ICs.

If your M.tec are in fact using the PC IC, then the linked article above should give you a good indication of what you can expect from your chips.

Hmm. There's a strange dimple in the end of the chip.
The coding is of a (PSC) Powerchip's IC but it doesn't look like the one's seen in recent TwinMos' modules.
It's something from Powerchip that TwinMos doesn't use anymore.

What mobo do you have?

Per the pics of ICs showing up in that linked site, Elpida seems to be the only actual manufacturer that has the dimple on the end of the chip like the one on the M.tec above. The others that have some ICs with it are module makers, not actual foundries, if I'm not mistaken (which I could be).
The other thing to keep in mind is that, per my understanding, there are only a few types of machines that "package" the ICs so it is possible to have similar looking ICs from different companies. Winbond was unique with its two larger dimples, small hole and "staples" on the sides and also Micron, which has the half circle cut out at the end with the white edge around the edge of the cutout is unique. Infineon, Hynix and Samsung are also consistent in their packaging, but some of the others are hard to keep up with.
With respect to the question about higher memory voltages without a mod...DDR Booster, if your mobo is compatible.

why do you guys get his hopes up? back in the day twinmos used m-tec IC's which sucked for overclocking.
