TwinMos-Mtec mem...can`t find info

[buraz]

:bang head
this is my memory
2x256 PC3200 DDR Twinmos

Mtec

TTD7608F8E50D

I can`t find any info for it....can someone help me :bang head

I need info to know how much can I push up the FSB on my NF7-S


thanks

[RedDragonXXX]

I know that SP's are BH5's but I'm not sure if those are :shrug:

They might be.

[buraz]

I know it cold be that or UTT, well it luks like I`ll be doing a lot of testing...thanks

[Reefa_Madness]

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.

[buraz]

When I come home I will teke them down, make some pictures of them an post them here....then you will have more info....then we will se which one are they

thanks for the info

[buraz]

this is writen on chips
M.tec
0406D
TTD7608F8E50D
it is one sided RAM 256MB PC3200

there is a small dent on one side of chips, when I look on the side I can see two small dots on ich side of chips

my english is not so good so I hope you understand what I am trying to say

[buraz]

here is a picture of RAM chip

[buraz]

here is a side shot of chip

[buraz]

PLS I need to know is it winboud or something alse....an what kind....so that I know what moded BIOS would be best for me

thanks

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.

[buraz]

i thin it is.....becuse yesterday I maxed out at 220FSB

thanks for everything

[largon]

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.

[buraz]

well thanks agin...you helped me very much

[Reefa_Madness]

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.

http://www.techpowerup.com/reviews/TwinMOS/SpeedPremium

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.

[largon]

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. :shrug:

[buraz]

weell when I push my FSB over 220 I get RAM error beeps even with 2,9 VDIMM....so I think that is MAX for my RAM

OT question is thera a way to get VDIMM higher without VMOD-ing my MOBO

Big thanks to everyone for their input

[largon]

What mobo do you have?

[Reefa_Madness]

http://www.biwa.ne.jp/~yok/TENJIKAN-DDR.htm

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.

[crimedog]

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

[buraz]

well my MBO is NF7-S rev.2 CPU is XP-M 2400+.....I can get to 220FSB with ease but over....no way....even when I put my VCORE=1,85;VDIMM=2,9;ChipsetV=1,7
I losen up RAM timings to 2,5 3 3 11 but over 220 (220 and a litle more) I get
error beeps.....for my RAM

for now taht is max.....will try with some BH-5 chips.....if thenn I go over 220 I will start saving some money to buy two stcks

thanks again

Abit NF-7 voltmods (http://malvescorner.net/nf7.html)

[buraz]

electronic stuff isn`t my strong side...so no Vmods for me....but thanks for info

BTW...and PLS don`t be mad at me if I shold have done that all ready....could I go higher if I try L12 mode

[Reefa_Madness]

The L12 mod is a must on an NF7 is you are seeking higher FSB.

If you need it, you'll find a pic of the socket and the wire location about half way down the linked page. The next few links are just some sites/threads with good info on the NF7...again, only if you need it.

Hope that some of that will be of interst to you.

[buraz]

thanks for your input....will try L12 ASAP

mtec chips should OC well, i have only ever tested them out once, and that was a while back now.

[buraz]

....the thing is when I push the FSB over 220 or so I get no boot and beep error for RAM.....even when I take VDIMM to 2,9V colud be my Codegen 300W PSU isn`t best fot this....would it help to put chipset to 1,7V and shuld I cool down mofset and SB then....I will try to use L12 133 to 200 and then see what will hapen....but I don`t think it will help me becuse of the RAM error mesage

[largon]

mtec chips should OC well, i have only ever tested them out once, and that was a while back now.
The Mtecs you tested were presumeably UTT.
buraz's modules are for sure not UTT.
