Never noticed you used such low Vcore Tedy :am: Would never suggest higher than necessary, but you could safely try 1.6V (have a CBBHD 0450TPCW in the test bench that runs 24/7 and gets severely abused that I run 1.6V on, no prob)Quote:

what do you mean by that, if its bh-5 die, its BH-5.. they wouldnt say it was BH-5 unless its just as the old ones :stick:Quote:

Managed to fix this when i flashed the 310 Bios from DFI =) Thanks!
Nice.Very nice#s.Total crap for me at any voltage+aa4t.Geil pc 3500 beat it hands down at any voltage.Either newegg sent me bad cips ,or u guys are fulla s^^t.period
Whoa man, that's it. Blame it on us because you can't get your RAM to run at what you expected. That's the way to go. :thumbsup: :rolleyes: :rofl:Quote:

Otherwise, you could try it the way it's meant to be, edit out what you posted above, give us some system specs and perhaps we can assist you in getting the RAM to perform, in case it's not really bad/damaged.
Anyway, think before you post. This would make it easier for us and for you also. ;)
Send it back, it'll end up in the "refurb" section.... more good ram for US cheap.... seeya.

hi, i'm new here. i've bought in poland 2x 512mb twinmos (non sp) like this, at the label there is aa4t (so should be ch5), but cpu-z shows me 4 last signs: cad(t) - (it mean's they have powerchip die). what to believe ? is it possible that spd is bad programmed ? or i have bad labels on the ram ? sticks do memtest with no probems 8h at 250 1t cl2 2 2 5 2 7 15 @3.6V but ocasionally have blue screen/reset in win xp. have anyone know what's going on with these sticks ?
If they were the CADT chips, it would be very, very unlikely you'd be able to even boot at those memory settings. I'd say they're UTT chips. The BSOD/reset could possibly be caused from many other things.Quote:

They are 05094 TMD7608F8E50D AA4T, but they are NOT on the BP pcb ( as stated by Alonso, AOA=BP and A8A= KG 6633, which is exactly what is printed on my PCB's).
I also just got a shiny new DFi Ultra-D, so as soon as I get a PCI-E VCard ( If I had known the EGG was delivering today I would have gotten 1 on the way home... DOH!! A day early).
I'll let ya'll know how I make out with them,

Thats what I just got Charlie, codes on my chips in the post above, same on both sticks.Quote:

These Twinmos TMII400/1GB and any other with the chipset specified above are like a bicep the more u work it the bigger and stronger its gonna get. I have AA4T=CH-5=UTT, when i got them i couldnt get passed 200 FSB SPD Timings, now after burning them in 250 FSB 2-2-2-5 3.3 voltage (no mods). There is a process for this that I will specify shortly and needs some attention and patience.Quote:

3. Run memtest86 and loop "test 5" for a few hours
If you get no errors at your this speed, increase FSB, all the way until you start getting errors. When you do, continue to loop "test 5" for hours, the errors will decrease or will be less frequent, soon enough they will magically disappear all together. When this happens, increase the FSB and try again.
4. About the errors... a few is ok, but not a thousands. You want the ram to be forced all the time, and too many errors, the program goes into subroutines to log them instead of jogging the ram. So a "few errors"...10-20-50-100 is ok, not not K's. I liked 10-20 max PER LOOP of the test. The thing is, when errors are found it takes a break to record the tally, so the less errors u get the better.
5. The idea of keeping the error rate low is that the program will take time away from hammering the ram to "tally" the error, and the idea is to hit the ram as hard as possible, so try to target the FSB at the point where errors start but not so high that ALOT of errors occur (as this would take away from the overall effect we are trying to acheive...(beating the ram senseless).
6. For burn in its not required to set it to the highest voltage possible. Instead, and this is confirmed by OCZ, set the Vdimm to 3.2-3.3V and run it in memtest at as high an FSB as it will run without getting more than a few errors on a pass. Now at that FSB point, give it 24-72 HOURS of burnin, keeping the ram cooled with a fan blowing on it. Hopefully the ram will "improve" over time and the errors will reduce/disappear. Try increasing the FSB a couple Mhz every say 4-6 hours, and continue burning.
This info Was supplied by Marcus d that did an outstanding job getting this info.
I will add one more thing, my process was different I used all tests and never got errors on 5, just on 8 and seven, I think it my be different for every one, pay attention to the first pass so that when u see the amount of errors write it down and compare it to the number of errors u got on the other passes, and ull see how the start decreasing.My first pass had 177 errors, second 143, third 90, fourth 10, fifth none :D.So try it and see if it works for u. Ill post pics later so that u can see my results. :toast:
If ur thinking why I havent pushed them more, ive just been plain lazy, i just got World of Warcraft and im hooked, ill try higher and post my results when wow fever dies out

lol, you pretty much copied and pasted uwackme's ram burn in guide from like two years ago...
Choya061:
"177 errors, second 143, third 90, fourth 10, fifth none"
That was a fast =)
Other needs days and nights and you did it on..10 minutes ?
Took about 5 hours of testing
I have a pair of the aa4t chips and can't break the 240 barrier, I've gotten up to 238fsb 3.4V. 2-2-2-8 . Also I had to bring my chipset voltage up from default of 1.6V to 1.8V to hit 238. The chipset heatsink runs very hot even at 1.6V, anyone running the nf3 chipset voltage at 1.9V with the wimpy heatsink? I'm a little hesitant to run 1.9V on it.
I have an 80mm fan blowing on them and a 80mm blowing up towards my chipset. I'm testing at 2-2-8 2- and the rest on auto, I have tried 2-2-10- 7-15(the rest on auto) with no improvement on overall speed.
Seems like my chips are a bit stubborn or I'm overlooking something, any ideas? Also I adjusted the 3.3V pot on my Forton to 3.6V to hit 3.4 on the Vdimm.
did you try 2-2-2-5?
try 3.5v on the ram and burn them in. should get you atleast 250
What Chip hawe a This Memory TwinMos PC3200 1GB Kit (2x512MB) (Winbond UTT)
How is overclock?
Won't boot at 2-2-2-5 3.4V I havn't tried 3.5V but it looks like I might have to. I've been buring in at 231fsb 3.3V 2-2-2-8(the last 20hours)Quote:

I have never used one, is it as simple as sticking the red probe into the ram slot to get the Vdimm reading? What about the black probe? Not to worry, I don't plan on using it untill I get a good qualified answer.

My meter just has on on/off button and says "Automatic Selection,VAC,VDC,OHMS. no individual options.
Now I just need to figure out which mosfet it is, I just saw a picture of my board yesterday and they were discussing this very same procedure. I thought it was on this thread. hmm..
Edit, I think I found it it's black and says Richtec on top of it with 5 silver bars/pins connecting it to the mobo, do I touch one of the bars/pins or on the top black part?
Thanks for the help, I really want to be sure how much volts I'm using before I go to 3.5V on this ram.
any body oc the 2x256 twinmoss 256?
