Same markings as the chips I just recieved today from the egg. Burning in at 240mhz 2-2-2-5 3.2 volts no errors yet. And this is on my IS7 P4 setup. :toast:

are you guys burning in Dual Channel or Single Channel?

I'm running Abit AS8.

My single chanel is at like 250Mhz, but dual just SUCKS for me.

Any info will greatly be appreciated.

Burning mine in dual channel. Right now I'm at 245 with 3.3v. Going to leave it burn in like this overnight.

I have the same stick, week 6 05'. Burning in nicely at 250htt at 3.3v tight timings. SC on my DFI LP UT.

hmmm

Mine are all dual channel, 1st set im typing on @ 250mhz, though StressPrime fails above 245Mhz after a few hours..... may easily be my CPU/Vcore not the memory. Air cooling is limiting me, water will be next purchase.

2nd set is going to get overnight burnin @ 3.25V memtest#5 230Mhz 1T 8,2,2,2.0 then I will move it to the Infinity for 3.5Vdimm testing.

3 out of 4 sets of TMII (non-SP) Twinmos are running 240-245Mhz, 4th set was DOA and sent back for RMA. So all 5 of 6 sets performed better on NForce2 then any of the BH5-BH6-CH5 ive ever owned/tested.

A serious bargain in memory no matter how you look at it.

Just placed an order on Newegg , TwinMOS Dual Channel Kit 184-Pin 1GB(512MB x 2) DDR PC-3200, Model TMII400/1GB - OEM - Hope to overclock it up to 250MHz or more with tight timings 2.0-2-2-5-1T :slobber: Will post back with results :toast:

hmmm

Unfortunately, people have been saying latest deliveries of these dont come with UTT chips on them. Im a bit worried as I RMA'd a bad UTT set back and really dont want non-UTT coming back my way.

Hope it works out for you.

I just got these sticks in earlier this week and they are NOT the UTT ICs. They look nothing like what was described in th opening post. Hopefully you lucked out. At their SPD timings, mine'll do 240 at 2.9V. If i increase volts, the mobo screams at me or no POST at all.
G'luck.

i got 2x512 sticks of the speed premiums today but one of them was DOA. =( they both looked opened (found hairs in packaging) so i decided to RMA them and get a new set. i'll post my results when i get another set.

do you gets get alot of DOA speed premiums or twinmos in general?

Picked up a pair of these from cpucity.....they are AA4T, MTEC 50D labelled IC's on the std pcb.
CPU-Z shows them as Week 08 Year 05's......currently memtesting at 260 and 3.5v for burn-in.....no errors so far !!
But for reference, my OCZ 2 x 512 BH-5's run 265 at 3.4v....without any errors.

hmmm

Second set 240Mhz StressPrime stable @ 3.5V, a little slower than set 1. We'll see after burnin at 3.5V. 3D stable at 245Mhz. A couple errors memtest#5 @ 250Mhz.

lookin' good uwackme, when you get a free minute away from that BIOS screen would you mind posting results for your new pair in my voltage scaling thread?

I'm going to include results for the new BH and the 4000VX soon as results start flooding in... would really love to see how these new BH are going to do in my hands! :D A 25watt 2200MHz Turion 1MB L2 + gig O new BH... oooh yeh!

Twinmos PC3200 Speed Premium listed as CH-5

I'm wondering when Twinmos changed their product page for Twinmos PC3200 Speed Premium to list the die used as Winbond CH-5 and the Twinmos PC3500 Speed Premium as Winbond BH-5. My pair of SP 3200 sure act like the CH-5 in that they seem more comforatable running 2-3-2 in windows. Anyone one know how I can get my hands on some of the PC3500 sticks? :confused: Although my current Twinmos 3200 SP will run test 5 errorless at 262 2-2-2-5 3.4v in memtest, they freak in Windows at just 250 same timings. :confused:

Edit: Just saw this from Alonso:
CH-5 / AA4T / AA=0,13um 4=Winbond
BH-5 / 1A4T /1A=0,15um 4=Winbond

I thought that a "4" in the third character slot meant BH-5. I'll need to take look at my sticks.

Edit: Bah! Confirmed AA4T!

Been messing with my AA4T. Initially when I got them 1 Stick does 260 2228 @ 3.4V and the other well just plain sucked.

Anyhow, messed with the bad stick last night and it seems it's more CH-5 than it is UTT haha. Ras to cas 3 and it runs great up to 264 =/

Can you tell me exactly what do the IC's say ? I have one Mtec xxx 50D Twinmos here but i don't think it's a good overclocker... (I only have 2.85 in my bios options for vdimm) So i can't give them high voltage...

Hi, I'm new here. So I recieved these sticks and here are my results so far @ 3.3v. My board won't go any further without a volt-mod which I may attempt later on. But yeah, it's still NF2 so there's really no point. I'm sure these sticks would be amazing in an NF3/NF4 board but I don't have the money to upgrade the system at the moment.

edit- a bios flash fixed most of my problems, guess the board was unstable and the ram was perfectly fine.

Yea I saw the price and that's pretty damn cheap for some UTT. I might be picking some up later this week!
