PSC IC's... Anyone heard of them?

[Postal Dude]

Hey guys. I jus got some twinmos speed premium 3500 and they have PSC IC's on them according to the company i bought them off. The number on the IC is

TMD7608F8E44F
They are pretty plain IC's, a dimple in the lower left corner. That number, and the production date

thats Powerchip.

from what i heard, you could get something like 230-240MHz out of them.

BTW how does P/N end on your TwinMOS:

BTW how does P/N end on your TwinMOS:

I had some memory with PSC but they were absolute crap, didn't even do 220mhz at any timings...

Look if it's AADT or not, you could also have Hynix D43 which is much better than PSC

something tells me he's getting a loooot better than that

what should be P/N ending with for Hynix?

AFAIK:

1A4T ---> Winbond BH-UTT
AA4T ---> Winbond CH-UTT
AADT ---> PowerChip
CADT ---> PowerChip
AA-T ---> PowerChip

speed premium stuff also?

[Postal Dude]

yeah. There is another thread here at XS. Theyre relabelled Hynix D43 ic's

[ozzimark]

why the sad face? D43 can be very good when properly tweaked

exactly, Hynix is not bad stuff.

Postal Dude, can you give me a link to that other thread?

[Postal Dude]

can anyone give me a link to hynix d43 tuning?

High5, if you go into xtreme bandwidth search for xtreme twinmos memory

I jus changed a few settings in A64 tweaker. From ones i knew worked to jus a little tighter. It failed after 10 hrs prime blend test. Options i changed were....
Read Preamble 5.5ns to 5ns
Tras 8 to 7
Tref 200Mhz 15.6us to 200Mhz 7.8us

Can anyone tell me which one is most likely causing errors?
