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

[LorD_Kvadd]

aah your right...But what the hell. better to have too much than too little right?

Got it somewhat stable.. But I don't think it'll be stable in 270 DC.. Never... but I'm sure as hell going to try!

[Alaza]

I can't get anywhere above FSB221 on my Rev. 2.0 mobo, stable that is, and it's not my Mushkin. I tried 2.5-3-3-6... didn't help. So now I see that I should disable APIC. Should I just reboot, disable APIC in BIOS, format my Windows partition, and then I should get more stable FSB?

[Alaza]

I just read somewhere in this topic that the 10.5 multiplier provides better memory bandwitch. Here's my results from Sandra:

11x: 3397/3173
10.5x: 3411/3169
10x: 3384/3146
9.5x 3394/3137

[Stang_Man]

hey TicTac, can you answer this for me,

in what situation would I need CPC to be ON or OFF? I do not know which version of the d10 i want

CPC On for
1 x 128MB
1 x 256MB
2 x 256MB
1 x 512MB

CPC Off for
2 x 512MB
3 x 512MB
2 x 512MB + 1 x 256MB
3 x 256MB

You need a CPC ON D10

Yes ... you should read the changelog carefully... i already inform that multiplier 10.5 ... got bandwith spikes in it... 1% higher than any other multi

you need D26 Manta Rays XT CPC OFF bios

Vdimm = 2.9V in bios
Vdd = 1.7V in bios
Vagp = 1.6V in bios

PCI latency = 128clck
Ext P2p discard time = 1ms

that should do the job done....

APIC disable it this way.... update processor driver in Device manager menu to Advanced ACPI driver
reboot... go to bios menu ......then Disable the apic...

[tictac]

lol... nice job there

[di_entropy]

PCI latency = 128clck
Ext P2p discard time = 1ms


what do these settings change/help exactly?

just want to make sure before i go messing with it

[Sancho]

This bios kicks ass. I have gone from 231 to 240 stable 2-2-2 timings with only 2.95 volts. Bravo!

[Alaza]

I did. I just wanted to share my experience so people had an idea of how muth band width it actually gained.

PCI latency = 128clck
Ext P2p discard time = 1ms

Those two are BIOS settings, right? Never touched them before.

I already use D26 Manta Rays XT CPC OFF, but I was actually recommended to try Merlins BIOS because of the low FSB. And what is it about the D10 BIOS? Why are you modding that one, when it's so old?

I'm already at these:

Vdimm = 2.9V in bios
Vdd = 1.7V in bios
Vagp = 1.6V in bios

Just not the V-AGP. Isn't it at 1.55v standard?

[Jeff7]

CPC On for
1 x 128MB
1 x 256MB
2 x 256MB
1 x 512MB

CPC Off for
2 x 512MB
3 x 512MB
2 x 512MB + 1 x 256MB
3 x 256MB

How about for 1 x 512MB + 1 x 256MB?


[q]PCI latency = 128clck
Ext P2p discard time = 1ms[/q]
I'm also curious as to what these do.

[tictac]

PCI latency = 128clck
Ext P2p discard time = 1ms

that will make your PCI device

such as HDD,SoundStorm, ethernet,firewire

run alot smoother at high fsb

i'm using that setting

233MHz stable.... Mtec50D chip

But should we only use it, if we have problems with Soundstorm etc. when clocking, or should we change it anyway?

[LorD_Kvadd]

If you have trouble with soundstorm and pci devices check the southbrige. Mostly it's a cooling problem.

[TEDY]

tictac you should write some sort of manuals/tips for NF2 users

[Stang_Man]

CPC On for
1 x 128MB
1 x 256MB
2 x 256MB
1 x 512MB

CPC Off for
2 x 512MB
3 x 512MB
2 x 512MB + 1 x 256MB
3 x 256MB

You need a CPC ON D10

since i got different ram now, i needed cpc off..

check this, not bad for the volts
thanks tictac!

i did this mod along with the vmod with the pencil and i got my fsb from 220 to 240 stable

[Alaza]

i did this mod along with the vmod with the pencil and i got my fsb from 220 to 240 stable

And the pencil mod raises the VDD?

[Golias]

Yes, it does but IMHO i prefer the use of a VR for this so simple mod.

[tictac]

And the pencil mod raises the VDD?

If you mod Vdd make sure

between 1.75V - 1.85V

234MHz here :banana4:

nice what is that program that u are using to test stability?

im still using prime95 but wondering if there is something better

[KODE]

aah your right...But what the hell. better to have too much than too little right?

Got it somewhat stable.. But I don't think it'll be stable in 270 DC.. Never... but I'm sure as hell going to try!

Hi,

Nice FSB! can you provide me some info like Vdimm, Vdd, BIOS, OS used? any tricks you wanna share? I got mine at 262FSB with 3.4V but I couldn't go any further (BH-5 DC)

3.4v!! bios maxes at 2.9 for me did you do a hardmod apposed to a softmod to get that voltage?

[KODE]

3.4v!! bios maxes at 2.9 for me did you do a hardmod apposed to a softmod to get that voltage?

yep I did the VDimm mod, 2.9 in BIOS outputs 3.4V or higher if I want to, It´s just a hardware mod.
