nForce2 Tweaker V0.2

A Windows Program written by CodeRed @ XtremeSystems.org allowing tweaking to all nForce2 base board on:

- Memory Alpha Timing
- AGP Controller Latency
- AGP Bus Latency
- PCI Latency

Screenshot


Before running this program. Close any hardware monitoring software ( MBM5, SpeedFan, ...etc)
Turn it back on after nForce2 Tweaker tools already open.

Happy Tweaking

[tictac]

here are some comparison for alpha timing

this is with loosen timing: 6-6-6-6-3-6-6


this is with tight timing: 2-3-5-3-2-2-4



Gain some marks on 3d mark2001

and some memory bandwith about 20-50Mb/sec

and here is super tight alpha timing:0-0-3-3-0-0-3-3

here some feedback from user

JimmyPage @PCPerspective Forums
tested all kinds of settings, ended up at 1-3-4-3-3-4-4 read top to bottom. Provides greatest bandwidth (about 40MB/s more than 5-4-6-3-3-5-6, about 15MB/s more that 1-3-3-3-3-3-4) and doesn't seem to limit my FSB at all.

No errors at any speed up to the limit in Memtest.

This is done with 2x256 CH-5 in DC, btw

oh ya here some reference for Alpha Timing

Alpha Timing Parameters

T = latency/timing in number of clocks
DOE = ???
RRD = Row Active to Row Active Delay
W2P = Write to Precharge
W2R = Write to Read
REXT = ???
R2P = Read to Precharge
R2W = Read to Write

if u have any other memory timing register plz let me know..

Good job guys!

I've been using WCPCREDIT until now for these. I found that using 5-4-6-3-3-5-6 kills my bandwidth (by a lot) but allows sligtly higher FSB, so one step forward two steps back, pointless. I endedup with 1-3-3-3-2-1-3 for my double-sided 512Mb stick. I'd like to see what other people are running too.

Going to be really nice to try this little new addition to the tweak programs. However late is the hour :P And I must sleep so I will try this tomorrow if i have the time...

[charlie]

awesome!!!

[tictac]

i hope can add more option later.. now still searching

[blinky]

what timings does 88 35 and 32 correspond to?

[YoupY]

Very nice job CodeReb

Would it be possible to have all bios options in a windows based program?

That would really rock

The next revision will have more options. Tictac and I just have to work out which options can/cant be set from within windows.

BTW Dont thank me, thank tictac. He did all the hard work with the register values. I simply adapted A64 tweaker.

[YoupY]

Tictac great job

both you guys for both tools

Any change we'll see voltage options windows based, or is that impossible?

Isn't 27 3DMarks within the margin of error ? And how the heck did Merlin manage 267FSB on a NF7-s ?!

[tictac]

ok thanx...

267Mhz... no problem

[uwackme]

Values "8C" "25" "22" correspond to 11,2,2,2,2.0

[korvskall]

What settings would be the best for my 2x256 twinmos bh5 sticks

[tictac]

horey.. i just get trc & trfc offset

edited:typo error in pic

Auto Precharge
offset0x86h
F= enabled
D=disabled

[enduracell]

Outstanding job, thanks to everyone who contribute, and especially tictac for being all over it

looking into it right now

EDIT: tictac can you check the following interpretation of your screenie. In particular I need to know the valid range for each setting. Just want to get it right (first time) before I commit this to code

[tictac]

Codered i already PM u the register

All is 4bit register

except Tras = 8bit register

[DarkManX_BG]

Do I have to understand all these settings, or is it enough when I know that lower = better?

hope someone can help me find

- Data Scavenged
- Super Bypass
- Dimm Strenght & slew rate

register next

[uwackme]

I still dont get the AGP bus latency location. Why does Oskar Wu say it is one place and the tweaker has it elsewhere?

I guess that CPC on/off and CAS are two things we cannot alter from Windows....only bootup bios time these can be set?
