I tried different settings and when Trp is set to 3, memtest passes at stockspeeds. So 200Mhz at 2-2-3-8 @ 3.2V is memtest stable.
210 with same settings is also stable, but 220 fails. I cannot get 220 stable now, even with more volts.

Btw where is the vdimm measuring point on this board? I think the bios is incorrectly reporting the vdimm.

Sorry to hear bro... I think you have an RMA coming up.

1) I would test the modules individually first

2) The vDimm testing point is on that big mosfet with 5 pints all on the one side... and big tab on the other side. Take the reading from the big tab.
You'll find the mosfet at the top right corner of the board, when it is installed in a case. For me that point is usually bout 0.3v-0.5v overvolted... but my rails are higher than stock.

I decided to give up on memtest and tried some 3dmark.
2k1 is stable at 10x265 2-2-2-8 @ 3.5V so I don't care about memtest anymore :)

265 is Pifast and spi1M stable also.

ok ... here we go !!!

all test at Dual Channel
setup is
Winchester 3500+
DFI Ultra-D (0209 BIOS)
2x512 Twinmos UTT (DIMM #1 is 04514, DIMM#2 is 05044)

timmings
2-2-5-2-7-15-2-2-1-1

3.1V = 255
3.2V = 259
3.3V = 263
3.4V = 267
3.5V = 270

1 wonder DIMM does
3.2V = 263
3.3V = 267
(haven't tested under 3.4 and above since it was it's first run and i already burned a DIMM :( )

3.5V are sliiiiiiigtly unstable under XP, maybe they need HSP on them (and they will get them soon :D
3.6V will be tested with HSP on them
(waiting to test one more dimm in a couple of days!)

At least we know why people with Intel are not postings results.

Dual channel
3.1v 200 (error)
3.2v 200
3.3v 203
3.4v 203
3.5v errors
3.6v errors

Singel Chanel
3.1v didnt try
3.2v 220
3.3v 222
3.4v errors
3.5v errors
3.6vdidnt try

cant get 250 FSB no matter the timmings or volts :confused:
my Geil runs 2.5-4-4-7@250 @2.9v all day long..

P4C800-E
2.8 sl6z5 ( 260@1.80v )
RAID0 thro the ICH5R
OCZ powerstream 520w

Thank god i'm getting an amd64 sytem for gamming.
I'll try a amd syatem, a Gigabyte K8NS Ultra 939 going to vmod it.
and most likely a 3200+ cause i want 10x250 2-2-2-8.

edit...still testing i'll post if it gets better.
edit...man $250 for 2-2-2-8@202 DC@3.2v. I think kingston value ram is as good as thease. whats? going on here?

I only ran the settings that related to 200MHz (1:1) ratio... but here are my results with the settings I tried (CPU @ 10x256):

3120 : A close 2nd. Sandra bandwidth = 397x/397x , SuperPI 1MB = 33s-34s
0064 : No POST
1560 : 3rd best. Sandra bandwidth = 393x/393x , SuperPI 1MB = 34s
0032 : Horrendous Bandwidth!!! Sandra bandwidth = 500/500 , SuperPI 1MB = 1:02 m
0780 : 4th best. Sandra bandwidth = 381x/381x , SuperPI 1MB = 34s
0016 : No POST
3072 : Best for me. Sandra bandwidth = 397x/397x , SuperPI 1MB = 33s
0128 : Sandra bandwidth = 252x/252x , SuperPI 1MB = 35s

biggy props aCid :toast: That looks real good... maybe I'll see 265 with 3.3v if I get the right combo :)

i just noticed on the first post that the intel results look about the same as ours..
i thought these sticks werent good for intel?

you need to adjust a few settings on intel to have "good" results sometimes.

DFI NF4 Ultra-D is the board

+ i have the impression that 3.3+ Volts are causing the system stability issues
hope ill have the chance to test one more time Hipro5's Maximizer with that board ;)

Are there any programs for nForce2 mainboards to set memory timings?
I am running Twinmos Speed Premiums in dual chanel at 245mhz cl2.0 2 2 11 on my Shuttle barebone at 3.17V. memtest test 5 45passes errorfree
But I cant set 1T anywhere in this bios ;/

Best i can do is 3-4-4-8 @3.2v @240fsb dual channel. 3d stable.Dont know about memtest cause i got sick of seeing errors @ anything above 202 fsb at any timmings or volts.

Just ya know when ya geta bag from a friend and he comes back and it's way short of what you thought it would be. Thats how i feel right now. :mad:

yeah 400@2-2-2-8@3.2v is just about all ocz will stand behind. Not like they will swap thease out for some pc4400.

I bought thease with 250FSB in mind, with anything better than 3-4-4-8. (Meaning 2.5-3-3-7@250fsb@any volts).

i dont know what i'm going to do. Spend $250, just so i can spend another $300-$400 for a AMD MB and CPU just to feel like i didnt get ripped off :cussing:

P.S. i might see what a hammer and drill and some other tools can do for thease sticks. WILL POST PICS OF THAT. lol

anyways thats my experience.
Peace, Nugz

Have you done the burning in? I have no problem with my 4 X 512MB TMSP/0503/44D on i865PE(Abit AS8) and i875(Asus P4C800 Dlx). This is a screenie for P4C800-D. I can get higher on i865PE because of the PAT thingy. Disable PAT on i875 won't help to get higher FSB. Anyway, I am happy with 250 FSB @ 3.5v with PAT enabled.

heres mine on an intel platform @ 3.6v...guess i got lucky.

:toast:

edit: when i first got them, they did about 205 2-2-2-5 or so at 3.2/3.3v. anyways, what i did was to burn them in at 3.3v 2.5-2-2-5 at whatever speed they would do with the least/no errors in the first 5 passes of test 5 for 8 hours. did this for about a week or so gradually increasing fsb and voltage. burning in worked for me. hope this helps.
