Nf2 Guru i need your help (Skinnie, kitfit1, clay and all others)

[ebdoradz]

i have put the TCCD mem i bought from Angry in my nf2 board

 

system spec are :

 

DFI Lan Party nf2 Ultra-B

AMD Athlon XP-m 2500+ (1.45V version)

2*512mb of Centen Advanced DDR400 TCCD (blue heat spreader)

Fortron 450W dual 18A rail

BBATI 9800pro

2 80gb raid 0

thermalright SLK-900A + 70cfm fan @ max

thermaltake armor full tower with 3*120mm + 1*92mm

Zlaman heat sink on both NB and SB

 

i have some prime instability issue and i would like to resolve them

 

240*10 set in bios

mem volt = 2.8

cpu volt 1.725 (used 1.700 in my previos OC 12*200 and it was 8hrs prime stable)

chipset volt = 1.6 (tried 1.7 but prime failed too)

ram timing 2.5-3-3-3-11 1T

alpha timing = (see include nf2 tweaker print screen)

 

cpu temp idle 34. load 40

chipset temp idle 32 load 37

board temp idle 26 load 29

 

ambient temp 19C

 

so far that setup is memtest stable for 10hrs but it crashed prime @ blend in less then 1 hrs and crash prime @ large FFT in less then 40min

 

any clue?? or suggestion??

UPDATED:

 

i have try a Small FFT prime run @ 1.8V 240*10 the test ran fine for a 5 hours until i went to sleep and when i wooke up this morning the computer was on a BSOD

 

should i go higher on the vcore or i will need to tweak the ram a bit??

[kitfit1]

Are those Alpha's the Auto settings ?, or have you set them yourself. Vdimm is too high for 240fsb with TCCD, set them at 2.6vdimm. Believe it or not ebdoradz, too much vdimm with TCCD produces the same result as not enough vdimm does with other IC's.

[ebdoradz]

thnx kitfit for that reply,

 

its actualy the 1st one on 3 diff forums :S

 

the alpha timing are set on Auto. should I set them manualy? im not quite familiar with those alpha timing .....

 

i will drop Vdimm to 2.6 and see what it does and for Vcore. is 1.825 V for the Cpu too high for that OC??? right now its falling prime on both blend and large FFT with 1.825V and 1.7 on chipset

 

i will start memtest tonight be4 going bed to see if the ram will do 240fsb on 2.6Vdimm

[ebdoradz]

ok kitfit1, i have chekc my rails on the PSU with Digital multi meter and all voltage where taken under prime and for 5min those are the min-max i have record

 

12V = 12.06-12.12

5V = 5.06 - 5.08

3.3V = 3.31 -3.32

 

so PSU is now out of the equation

 

i've follow your tips and lower the vdimm to 2.6V and lower my cpu to 1.7V. alpha on auto ... and start memtesting. the mem did a eror in test #6 and then the computer froze. i've put a bit more volt on the cpu. and now testing.

 

since i no one have test the nf2 with those centon TCCD stick, should i start by using someone tccd setting for my alphas like skinnie or clay's setting they posted in the OCDB???

[ebdoradz]

i tried 2.6 and memtest put me a error in 30 min so i decide to put 2.7vdimm, and i change the T(RC) from 13 to 12. memtest put a error in about 18min and then the computer sudently stopped.

 

i have try to boot it but no luck all the fan turn's on but no display ...

 

tried a 1 min clear cmos but no luck

 

i will let it clear for a couple hours hope i havent corrupted the bios ....

[kitfit1]

Using someone else's OCDB settings is probably the way to go. I must admit, i can,t remember the alpha's that i used. But if you look in my thread "can i do better", I'm pretty shure they are posted there somewhere.

[ebdoradz]

if i can get my board to boot i will try those in your thread

 

until that i must try the 24hrs clear cmos, or order a new bios chip from Tmod

[kitfit1]

I would have thought you would have a spare bios chip by now ebdoradz, you know how easy it is to corrupt the NF2's bios Defo don't lower T(RC) with TCCD. I think i may well have left all my Alpha's on auto as well, so leave them there until you get a stable clock.

[ebdoradz]

i,ve lower the T(rc) to 12 because i saw it in a OCDB with TCCD

 

i,ve learn by my mistake

 

could a 24hrs clear cmos work in this case?

 

and BTW the ram put error on my with 2.6V (2.5-3-3-3-11 1t alpha,s on auto) has you told me so when my board gonna be alive i will try 2.7V and start from there

 

should i got for 1.6 (stock) or 1.7V on chipset?

UPDATED

 

hot flashed my nf2 bios with my nf4 mobo

 

flash was succesful but the classy lady refuse to boot

 

it show me LED 1 and 2 then LED 3 then LED 4 and nadait stop there

 

i have check in the manual and it say's "Early program chipset register before POST"

 

what i do??? should i order a new chip from Tmod and see what it does or should i sit in a corner and cry???

[t_ski]

Try these:

 

Clear CMOS (as directed) overnight

Remove CPU and reseat

Try 100MHz jumper

Try cheap PC2100 ram

 

That's all I can think of to start with. Read up some more on this:

Sometimes it could be several things all-together. I had my Infinity eat the BIOS chip, then I got a new one and still had to go in with the PC2100 to get it to boot after I replaced the chip.
