ABIT NF7/S Rev2.0 Modded Bios : D26 Black Mantaray

[tictac]

running on Mtec 5D right now

230MHz stable 2.5-3-3-11

looks like re-label Samsung TCCC chips :-/

[Noktar]

Very good Bios.
Before: 215FSB
Now: Max post 240FSB

Running at 225x9.5 1:1

Question: How much Volt I can give with stock nf7-s cooler ? Now I', running with 1.7V and 225FSB ! Is this o.K. or will the Board die

[tictac]

i used to run 2.0V vdd with stock abit cooler on NB...

now running at 1.7V 233MHz 2.5-3-3-11 Mtec-50D

And special thanks to ABIT Indonesia:Spectrum

Thanks to Mr Alexander Zurrie

got new VGA from them... ABIT Siluro FX5200DT 128MB

Nice Bios, thx



But why ist the Memory Performance sooo low, if u use Multiplier
below 10x ?? with 6x260 i have only 3550MB/s and with 10x260 i have
3930MB/s

The maximum Memory bandwith efficiency located at multiplier 10.5 on D26 Manta Rays XT

use multiplier 10.5 you will get higher memory bandwith

[tictac]

with 2-2-2-11 timing dual channel at multiplier 10.5

Maximum memory bandwith efficiency will hit 97% / 91-92%

Why you only god a GFX like that ?
I only tried with CL2.0 !
Good Bios.
Is there a TicTac Bios with 3V+ VMem ?
Can't get over 1.85V on CPU

You got pencil?

here you go... Vcore Mod with Pencil trick

Mr Dimz in Overclockerindo.com have found new way to decrease Vcore fluctuating & undervolt issue just with pencil trick... nice

Here is the mod:

Transalation:

3. Fixed Undervolt Vcore
1 & 2 . Fixed Fluctuating Vcore

Theory:
decrease R vcore feedback & vsense HIP 6301

Vcore mode with Pencil trick by Dimz

SRY 4 that silly question.
But, what to do?
Only "wright" on 1,2 and 3 with a pencil ?

[LorD_Kvadd]

is that with 2-2-2-11 1:1?

:thumbsup:

ya its hard to keep >250Mhz stable with multiplier higher than 10

That was with 2-2-2-5 timings actually These strange corsair sticks doesn't seem to want high vdimm to get far with tight timings I think it's BH-6.

Think the damned vdd is limiting me. Can't get stable past 243 because of when I do try increasing vcore then it's just like the chipset doesen't want to play anymore. Can't use the mouse or keyboard but the OS is still running. Like 8rdavcore still updates and everything. Sounds like a low VDD don't you think?

[Noktar]

I need a better CPU.
Mine only does around 2200Mhz

I'm reading xtreme forums for a long time, so here is my first post
TicTac thank you for your great work!!
Using your D26 Manta Rays XT Bios I'm able to achive this :banana4:
VDimm: 2,9V
Vdd: ~1,85V
+3,3V: ~3,6V
+5V: ~5,3V
+12V: ~12,3V
CPC: on
CPU Interface: enabled
2500_superPI

Before flashing to your Bios the highest FSB I could get SuperPI stable was 235Mhz...so this is just insane
Is it possible that you add an option to switch on/off the Manta Rays bootlogo?
Thank You!!

That looks really good!!! How much did the increase in VDD do?
Seems to be really nice memory too

[TheRealElch]

Before flashing the TicTac Bios I did allready a VDD increase to 1,95V but it didn't help.
I think the built-in L12 Mod did the trick
btw the BH-5 is week "307WE"

No, it's an APIC problem.

[Noktar]

Since d26 Command per clock enabled enabled my System is low oced unstable.
Full oced it's 100% stable.
Looks like I have to use the Command per clock disabled

You think?.. Hrm well now i have an excuse to format. Thnx for the tip

yes... just write on top of the resistor with pencil.... it will overvolt the vcore in no time

awesome

[tictac]

Yes it is... NF7S APIC Mode having some problem with High fsb & High Vcore/Vdimm

feel free to Disabled it....

hrm im having some problems with basically every bios! but so far d26 mata xt seems to be the best. heres my problem

i cant get my fsb over 210 with out it not being stable if i go to 211 its not stable ect. maybe im missing something

heres my current setup
210x12.5 @ 2630
vcore @ 1.9
mem V @ 2.7
northbridge @1.7
agp @1.7

and my system specs are in my sig. im running in dual channel right now.

mem V try set it higher....2.8/2.9V in bios...

FSB with 1:1 ratio really depends on Memory capabilities :banana4:

[FDM]

im still waiting for a magic 265+

acually I want to try to get higher multi/fsb combo working better. Thinking i might have to try APIC off, but last time I did that I lost 500ish in 01.

nah my i get a memory error when i restart the bios with the higher volts... mass beeping sounds like a siren

[Sancho]

Anyone here have to raise their vcore higher than normal with this bios? Before I was able to do 231x11 completely stable at 1.95v but now I need 2v to do 233x11. Im not sure I am comfortable with that high of a vcore...also it seems to fluctuate a little when I see it in the bios 1.99 to 1.97. Would heatsinking the vcore help stability or is that a powersupply issue? I have a antec 430W truepower power supply
