Need help w/ bios options on Chaintech ZNF3-250GB PRO

[`schr0et]

Had this board for 3 weeks now, VCore mod has been done to it. Setting 1.55 in bios results in 1.7V real time.

Using stock Mach II GT on:

A64 3400+ CAAOC 403 "C0"
2X512 XMS3502 (running 5:4)
GeForce 5900U 256
PCPC 425


Ok in any case the max I've gotten "24/7" stable is 2.7 Ghz, this seems damn low to me especially considering people are able to do 2.8+ runs and I can't even boot in anything higher than 2.74

So this leads me to beleive either:

A. I'm a dumbass
B. Bios options need tweaking
C. More mods are needed

So as of right now my bios options are as followed:

AGP - default
Chipset - 1.9V
Ram - 2.9V
CPU - 1.55 (1.7)

LDT set to: 4X (setting to 3X made no difference on overclock when trying to go past 2.7)

AGP Aperature: 128
Fast writes: Disabled when using ATI card, AUTO when using nVidia
Sideband Address: same as above

At the moment I'm really dumb founded as to what else I can do to increase my overclock, there aren't any new bios' out cause Chaintech is good like that, and I feel like I've used just about as many bios combo's as I can.

Any recomendations on how to achieve a better OC with this setup, and "tips/idea's" on how to try and acheive a better OC are much appreciated.

Thanks as always,

well... have you tried more then 1.7v?

[pkrew]

Have you tried increasing the vcore?

Edit: lol, must have posted at the same time

[pik-ard v1.1]

hm... i guess its a good idea then.

[`schr0et]

I've tried up to 2.0V with no difference

[pkrew]

maybe some different ram. 2x256 SS if you have any.

[pik-ard v1.1]

i dont think the ram itself is the problem. he has it running at ddr400, when it is infact, ddr433 ram.

the a64's are unlocked with multi's down, right? try different multi's, see how far you can go with each.

[pkrew]

True, but they can have problems with DS ram and 512 sticks.

[`schr0et]

good point, I'll stick in 2x256 and run em 5:4 and see if I get any better benchable, thanks.

[snowwie]

or how about just one stick of 512?

same thing really, 2 banks, and one slot is better than two, board doesn't have to suffer more juice, or something

my CAAOC 0401 chip was bad ( only did 2,750 mhz ) however my CAAOC 0352 chip was good ( did 2900 mhz )

how about clockgen? another divider?

Franck was warned and now clockgen is totally compatible with the NF3-250 chip... FSB and multiplier(s)

just an update of CG-NVNF3.exe

I just downloaded clockgen from cpuid.org is this the updated one? Or is it somewhere else?

Thanks again all,

yes it's that one
then? it works?

i've got also the chaintech 250 board.
htt changing by clockgen works, but multiplier doesn't work. Windows will freeze.
the vcore isn't displayed correctly. always show 1,50. and changing has no effect.



sry for my bad english...

ok thanks, I'll say to him

[`schr0et]

Yup changing HTT works fine, but still hasn't helped me OC anybetter, max I can run prime is still 2.710

Thats with 3X LDT, 1.9-2.0 VCore

Thanks for the link though

`s

[`schr0et]

Bah stupid board has 2.0+ Vcore shutdown!

Went to 2.1 and bam comp shuts down....

Highest benchable is only 2.710 (

sorry to burst in - but is the apg/pci locks actually working on this mobo?

[`schr0et]

yes

[//mAr]

ok, changing multiplier works fine, but only with one DDR Modul *DAMN*
i can run now
7*350
in 2:3




the 1:2 divider doesn't work, no boot.
LDT 1x & 2x also don't work, freeze by changing "fsb".
-> highest stable htt is 1050

if 1:2 and
ldt of 2 were working ...
525 htt - no problem. *dream*

i will test more later...
