NF7(-S) tweaking guide..to be updated

[sai]

Hi, so here's the guide I promised you!

If you got any questions feel free to drop me a pm or email !

OK these are the things you should do more or less in a chronological order for a nice stable high oc on nf7(-s).

1. L12 Mod (often needed to get high fsb)

Whether you should take the 166mhz or 200mhz mod is up to you, best is to try both and compare what's best for you.

Here's the link!

2. BIOS

A decent BIOS is one of the most important factors in overclocking and often underestimated. So check
tictac's
and
trat's modded BIOS
My personal favorite is D23-3Dfire Rev.1 ! But that doesn't mean it's the best for you, that's different from board to board.

Important BIOS settings:

APIC disabled (gives higher Clocks and is needed for high fsb and cpu clocks, but a small performance loss)

When enabling/disabling APIC you don't need to reinstall Windows! Just go to device manager->computer->choose between acpi-pc and acpi uniprocessor driver! 'SAE'

All "Spread Spectrums" - OFF
All cacheable things - OFF
CPU disconnect function - OFF
CPU Interface should be enabled (performance loss if not, but maybe higher clocks)
CPC disabled (performance loss, but may help when going for high fsb and using 2 * 512MB. Has less effect on 2 * 256MB. CPC disabled BIOS can be found at tictac's forum)
Turn off all devices you don't need like unused ports or so

3. Sinking !

I think the picture explains itself, these are all the things to sink. The red ones are more important than the green ones.



4. Vmods

There are about 2-4 mods you could need..

- Vdimm
- VTT/VBT (often needed when going above 3.2v, helps stabilizing high vdimm)
- 3.3v rail mod ( Pic ) for PSU (really urgent for high fsb and high vcore. If you're not getting any high fsb try lowering multiplier and voltage of the cpu, leave the vdimm alone and then try again with the fsb that crashed before)
- VDD (resistor)
VDD (with pencil)
(you have to find a sweetspot here, for example 1.6v works much better than 1.8v for me)

I think I don't have to explain anything and just give you the links, they're already well explained.

Voltage readpoints!

VDD



Vdimm & 3.3v



12v & 5v can be read at a molex connector.

P.S.: Just use a 1K VR for 3.3v sensemod. Cut the thin brown wire and connect it to pot. Cut the thin black wire and ground it with pot. That's it. No fixed resistor or so needed.
If the line is highly fluctating you might give the fixed resistor method a try.
- Cut the thin brown wire
- Put a 10k ohm fixed resistor in line
- Solder 1k VR to fixed resistor leg
- Ground the pot

Here's a nice drawing from Kameleon

Remember this is just a collection of mods, pics, guides and a bit of my experience and knowledge, if anyone feels abused, please tell me and I'll delete his pics or whatever.

Greetings to all the modders, reviewers, hackers, tweakers and especially to tictac, SAE, malves, the guys at motherboardfaqs.com, pc_ice and all I forgot !
