Xtreme Twinmos Memory!

I just wanted to add, since I have not, that when I got two sticks of speed premium a few weeks ago, and posted, I had gotten one stick of aa4t and one of aadt. I had posted I got two of aa4t. I was stupid and only looked at the first stick.

that first one has only been slightly tested - in a dfi lanparty ut with a super junky psu, I could only give it 3.2v, but it was doing 250 memtest stable. (couple errors, eliminated w/ fan). before I could give it a go on my good neo2, I went and fried that (note- the 24pin adapter on an OCZ powerstream is NOT optional.)
on my backup neo2, a junk refurb with a superbad 421 stepping or something, it was doing fine at 235, 3.4v, didnt go further with it, because I am testing the cpu overclock, and I noticed - it would not boot with a 166 divider. just would not - the "safe mode" kicked in eventually. Popped bh5 back in and the bh5 posts and tests fine at 280htt divided to 235, so it is defineately the ram. curious, anyone notice similar behavior? could jsut be this board, it is flaky.

the aadt stick went back to newegg, I am going to get a playmate for this aa4t as soon as it is back in stock. good 1gb kit for the DFI UT, or whatever future motherboard.

The "Divider Issue" is a known one with UTT modules... it happens with VX aswell. But it is only when the Neo2 is in the mix as far as I know...

well after i tried the mushkin, i got pdp tccd and hit 285mhz, so i don't think its cpu/mobo limited, should i be tweaking the timings with a64 tweaker?

6pm and still no 512mb sticks at newegg, whats going on. there usually on the money

1 single stick 05034 AA4T 245 2-2-2-11 25 Loops #5 OK
3.3vdimm

at 250 hundreds of errors :(

I tried 3.6v (LOL :D ) and 258 fsb... first hour no problem... then I fell asleep rofl
After 2 hours I woke up and had thousands of errors....wtf.... memory didn't feel hotter than the first hour :(

Then I tried 3.36v and 250 fsb which went well :)

2x512 DC again... see screenshot

TEDY , it might be a board issue aswell. remember that most of the best oc results with UTT is from nF3/nF4 chipsets. (mem controler on cpu?)
from my experience i'm currently burning mine at 3.1v (3.15v at MBM) @ 244Mhz DC 1:1 2-2-2 1T. at 245 memtest freezes... so looks like board limit here. (244Mhz is good enough for AN7 tho :) )

now changing subject.
i'm using memtest+ 1.50. at 244Mhz i easy pass #5 but i have 6 erros (each pass) at #7. looking at everyone's burning's it seens like none cares with #7 test... everyone run #5 loops concluding it's 100% stable...
#7 is a random allocation test (something like that) so seens to be an important test, imho... but should i reconsider that and just stick to #5 results?

:toast: 244MHz 2-2-2-X on AN7

is awesome :toast:

enok : maybe better cooling or some ramsinks on mosfests

all 6 modules have the same chips on 'm

I already post Setyotomo 315MHz 2-2-2-5-2T DFI LP UT issue at DFI forums

Hope Oskar Wu will read it & fix the Bug :hehe:

You guys can check it over here:

TEDY you running CPC on or off?

no way youll break 250 on an Nforce 2 with 2x512, especially with only 3.3vdimm...

i couldnt get my 2x512 bh-5 over 230 with cpc on, 245 cpc off... 230 was faster, each stick does 255 cpc on by its own though (3.3v). with 2x256 i can do 255 @3.3 and even 270 on a good day with 3.55...(CPC on)

yeah CPC ON of course :)

i'm running it single stick now....245 2-2-2-x seems stable at 3.3vdimm.

I'm sure sticks can do at least 260 with 3.5vdimm or si :P

affter a night of burn in i'm able to set it to 3.2v at 230 2-2-5
235 is not stable, not even at 3.6v!
crappy mtec

yep MTEC suxors....what did you payed for ? sell them ? or RMA :cool:

about €45/pc

not that much, but still

the pcb on the mtec is not soooooo good .. it really suxx on high vdimm ...

true, i also have ramsinks on all mosfets + 80'' smartfan with that thermo sensor on a stick.

@ tictac , tks but still waiting for ur bios! :p:

look at the other ram timings in the a64 tweaker shot!!!!

Does the Speed premium overclocks a lot better than the Twinmos with twinmos UTT Chips?

Thank yop.

if both have UTT chips... it's the same! tho some SP have BP pcb... but their superioty over the KO pcb is yet to be seen.

?? how do you know which pcb you have?

OT but i think we just passed the A64 oc'ing thread for total number of posts :toast:

it's the same pcb like the sp ones KO6633 ( if i'm not mistaken! )

tested my mem's today :)
# 1 : 261MHz
# 2 : 254MHz
# 3 : 240MHz
# 4 : 257MHz
# 5 : DOA
# 6 : 253MHz

3,65V, according to the multimeter
not too bad for out of the box, without burn in

pity one module is dead,
gonna rma that one with # 3...

next week burn-in :D
