hehe , my bt-d43 can do

275Mhz @ 2.5-4-4-10 1T 1:1 divider @ 2.9V ( able to run superpi and memtest )

285Mhz @ 3-4-4-10 1T 1:1 divider @ 3v ( able to run superpi and memtest but reboot after awhile )

screenshot of 285Mhz @ 3V

my ram very funny not much difference even though change from CAS 2.5 to 3

hmm .. feeding 3.2vdimm ar ..

you using that for daily usage ? you got any fan blowing on the rams ?

won;t the ram get brun due to high temp ?

bt-d43 doesn''t work well on tight timing. try loosen up the timiing abit. bt-d43 work best on 2.5-4-4-10 or 3-4-4-8. vdimm from 2.7-3.1 depending on the chip.

jz my 0.88 cent opinion

persoanlly i'm running 250 *2 = 500 Mhz @ 2.5-4-4-10 on daily usage at 2.6V

was able to benchmark and memtest stable at 285 * 2 = 570Mhz @ 2.5-4-4-10 at 3.0V

i'm using dfi ut 250GB mobo on amd64 socket 754

erm .. i think bout the vdimm thing it depend on the chip. mine kinda need higher vdimm for stability if i oc the ram to higher frequency.

coz when i ran 280Mhz on 2.9V vdimm it wasn;t stabel but when i up it to 3.0V it was able to run memtest for half an hour without error.

try loosen up the timing.

bt-d43 dun like tight timing.

2.5-4-4-* OR
3-4-4-*

will give you much higher fsb

set the ldt multiplier to 3 and try again.
i believe if you set it to auto it's 4.
240 * 4 it's abit hard on hte mobo.




i believe dt-d43 can do higher speed than this. should be able to reach 250Mhz.



vcore no need so high la. will get pretty hot. i read from dfi webpage the safe voltage is 1.65 oni



i'm using dfi lanparty UT 250GB here.

look at my sig pretty similar system we got there.

off topic where did you get your bios. didn't knew there is such new release of bios from oscar wu.

i heard some of the new bios is not very stable and problematic.

personally i'm using the 14/10 4V beta bios.



yes i enable cpu thermal throtling. and yes there is thermal throtling in amd64 s754 at least on dfi mobo.

try reading thru this url. most of my setting is based on the setting shown by anandtech. hope this help you. http://www.anandtech.com/mb/showdoc.aspx?i=2198

i attach a 285 htt superpi stable sreenie together with this post

when you are using 9.5 multiplier you are actually running at 270* (9.5/10) = 256.5Mhz instead of 270Mhz.

try using mulitplier 9 or any round number for better performance.

jz my 2 cents.

yes .. finally got 280Mhz super pi 1M stable on my bt-d43 KVR on DFI LP NF3 250GB

hehe .. good ram you got over there if can reach 275Mhz stable.


the highest i got for my bt-d43 was at 280Mhz benchable ... but now i can't reach tat speed anymore after i update my bios. sigh.

hehe .. manage to get my ram running 2.5-4-4-10 1T @ 3V

benchable at 282Mhz
bootable at 284Mhz

hehe .. no idea at all wheter can it be applied to your nf4. you go to try and then let me know

good luck !

i strongly recommend you not to over clock ur gc mem with the above setting. you might kill your GC. anyway i'm no expert in overclocking GC.

NF7 don't like BT-D43 ?

but i noticed most BT-D43 can do 250-260Mhz @ 1T @ 2.5-4-4-* on most board.

anyway here is a screenie of my BT-D43 doing 282Mhz @ 1T @ 2.5-4-4-10 as posted earlier on this thread.

try tweaking more and you might hit higher speed for your BT-D43

yeap, it was my friend.

hehe. tat was jz for benchmarking purposes only. i'm running it at 2.8V for 24/7
