FAILED!

What the hell is wrong????

Disabling dual-channel now. Here are the possibilities that I've conclude, please add in:

1) Dual-Channel problem
2) Motherboard can't support/has a probem with high-memory bus speeds
3) FAULTY RAM (pray and hope not)

Testing one by one now.

try a higher vdd...u have to consider whether the motherboard can support such high fsb...ure ram might be able to achieve high fsb but the mobo might not do so without higher voltage...another factor could be the divider coz some d43 will not run anything but 1:1

What mobo U using ? Mine, nf7sv2 has problem running dual channels on 2x512mb vene at ddr 400mhz no matter what I tried. Tried some Titac and Merlin mod bios too.
No help . But I can run them separately and reached 235 mhz at 2.8 vdimm. Now on single chan. 2x512mb.

Guess what?

I've exactly the same board

I've finished testing one of the RAMs on the single channel. I ran at 230Mhz, and no problem!

Now testing the other piece. Well if this piece of RAM fails, it's the RAM. Else it's the dual-channel functionality of the board

Anyway kenk, how do you disable dual-channel? I couldn't find the option in my Abit NF7-s. Thanks!

to disable dual channel, juz put the ram in slot 1 n 2 [DC is on 1 n 3 rite?]

Yah,

Just use the 1st two slots nearest to the cpu. I've done th same thing like U , n test 1 by 1. I'm more or less confirm it's the issue of the chips not ddr. For single I can't get pass 240mhz. @2.9vdimm

what bios currently ur using?

Here my BT-D43 running 240FSB with 2.5 4 4 8

i got my DT x 4 dual channel fail to boot on stock speed, at 2.6,
but i take out that stick put another one no problem
is it ram problem? can rma?

yup, mine also last time didnt need high vdimm...
try first at low vdimm...maybe at 2.85
prime it , then increase a lil bit....

Now using Merlin , D26 cpc disabled dated 9-2004 if I rememberit correctly.Anyway, this is the latest I can find.U mentioned the cpc beforebut doesn't seem to work for me. May be I have missed out something. Will try benching them again tonite.

BTW I have mine L12 mode with wire on socket, possible cause ? Thank you.

my fren de DTD43 ddr400 from kingston cant even boot at ddr333!

dunno wtf is wrong with the ram

well, there's a lot of possibilities such as..

timing
Vdimm
bios
misslot
kaput

i dunno bout u guys but my bt-j will fail memtest86 if the fsb is more than 210 with cpu interface disable...after enable it addi can run 250 11-4-4-2.5 2.9vdimm...running on d26 mantaray xt 1T

Got My Two Stick Of BT-D43 Just Now...From Czone..

Later Will Test It!

what the price?

u should try using the same bios as below

yeah, any link? tq

ok,i got sumthing in mind now.

1)my mobo is dual channel(2 on left 1 on right)
2)i got 2x256 dt-d43 n 1x256bt-d43(all ddr400)
3)should i put the bt on right side n dt on left?
4)if i use this method still can tighter the timing?

thats all.thank you....

hihi all ...
i wanna ask DDR400 BT-d43 is all CL2.5 or some got CL3 at the kingston label there ???
