Winbond is back with a vengeance!

Winbond is back with a vengeance! TwinMos VX!

We've all been trying to understand what chips do those OCZ VX use to achieve similar results that are remarkably similar to BH5. The answer is that TwinMos is using them as UTT CH5 chips. Achieving timings of 2-2-2-5 with 270FSB, these chips just like its ancestor BH5 will need extreme voltage of 3.2+ to achieve these timings.

Currently the cheap TwinMos (Non-SP) have them, but as said by a TwinMos tech over at XS the newer Speed Premiums will in fact have the new Winbond UTT IC's being produced by Infineon Technologies and will not come with the well known Winbond logo anymore. The IC's are summed up as Winbond UTT internally CH-5, what we are in fact looking for. Other manufacturers are yet to be confirmed using these new chips

It's not known that the chips could either come in the AA4T or AADT because this is just normal memory after all. Just have to attempt to be aware of the shipments. Your best bet would be to look over at XS and see what the TwinMos rep has to say about the new shipments or what users are gretting. So its all a gamble with these sticks at the moment.

IC Numbers
50D - Found on the non SP sticks, the RAM is rated at 5.0ns
44D - Found on the SP sticks, rated at 4.4ns

What to look for

- AA4T is the serial number to get, not AADT at the end of the serial number (4 means Winbond, D stands for PSC, and the AA = 0,13um)
- The two dots
- Metal dots, two on each side

Confirmed Manufactures
- TwinMos

I am aware of the UTT chips, but I thought they were essentially CH5 rather than BH5.

 

[Maxwell Murder]

As stated they are infact pretty much CH5

 

[larva]

Then perhaps it would be a lot less misleading to compare their properties to CH5 rather than BH5 twice in your opening paragraph. I see now were you mention CH5, but you mention BH5 twice as often and in an much more obvious place (The point being a person could probably buy CH5 pretty cheaply on the used market).

 

[crimedog]

i've always wondered if these UTT chips make as much heat as bh5 or less (or more??)? because everyone runs them with high volts and people were so scared to run bh5 with high volts.

Also check out this topic about these windbond chips appearing in Twinmoss memory. We've been discussing this for a few days now. Also I think it's worth noting that those stores listed in this thread aren't guarenteeing which chips will be in their stock of Twinmoss ram.

Just wanted to start a concentrated thread on this stuff.

 

[SteveOCZ]

Infineon makes CH-5 still......well they never stopped. They just call it C-die

Would these Infineon be the same as the Winbond UTT, as per the news releases I've seen on the topic, the blanks that Winbond is selling are excess capacity that Infineon does not need/cannot use.

If so, how would a person be able to identify these Infineon labeled Winbonds?

 

[jcw122]

wow those 512 sticks are CHEAP! but are these things warretied to burn in hell (v's baby!) and come back with a warrienty (like OCZ's VX?)

 

[mattspalace]

Certainly cheaper than what OCZ is asking for..

I heard these were going to be inexpensive - I don't really call the current prices for VX 'inexpensive'.

 

[Reefa_Madness]

At $100 less per gig...you just "self warranty".

After all, bh5/bh-6 were spec'ed to be able to handle 3.6v and OCZ has warranted their VX to 3.5v +-5% (which they wouldn't do if they were worried that it would fry at 3.6) therefore I would surmise that this stuff isn't going to wilt running 24/7 at 3.4v-3.6v. Granted, 4.0v is another story, but then VX's warranty isn't going to help you there either. If a stick with the Winbond UTT does fry, replace it for $80 and you are still $20 ahead.

In stock now at Chief Value

 

[Reefa_Madness]

Do these guys ship overseas? I've got a friend in New Zealand looking for a 256 stick and the egg doesn't ship there.


edit:

Just went to their site and it says they do ship overseas.

 

[mxa]

I'm interested in the TwinMos memory, but I'm curious how you guys are guaranteeing your getting the correct chips? Just taking a chance or can you call newegg and specify the chips?

 

[crimedog]

after reading some recent results of the xs thread i'm glad i didn't buy that memory, it seems like a real gamble to get winbond chips or not

 

[SteveOCZ]

I don't think so. The UTT seems to be cheaper than the c-die so unless they are downgraded chips they must be different

 

[SteveOCZ]

I heard these were going to be inexpensive - I don't really call the current prices for VX 'inexpensive'.

It's true, but the other companies do not hand test their ram to run 240FSB 2-2-2 and not all of these chips run those timings or speed. I also don't think they have warranty coverage/service like we do. I'm not saying the twinmos sticks are crap, just letting you know where the price difference comes in.

 

[Rustafur]

Just like so many other pieces of computer equipment, something isn't nessisarily more expensive because of its components. You're paying for customer service and warenties.

 

[Reefa_Madness]

Thanks for the response...now for the second part...how can I identify the Infineon C-die if I was looking at an Infineon stick (forget anything to do with the Winbond UTT).

In other words, if I was looking for CH-5 from Infineon, could I identify it from the face of the chip and does OCZ use any of these chips in your products (if so, which ones).

I am holding two 512MB sticks of OCZ PC2700 Value Series in front of me which are using M.tec chips dated 0430. These chips have the familiar Winbond-looking circular dimples, the small hole in the lower left corner and the metal bands/staples along both the left and right edge of the chip...would this possibly be Infineon ch-5 or something else?
