Give me a few more hours ... its written but untested, and I am still at work

then good afternoon

I'm sleeping

At last, I have finished the first beta version of A64Tweaker.

Heres a sample screen shot:



This is Version 0.1 and is still quite rough, but it works
I have only tested this on an AN50R + C0 stepping 3400+ (S754), but it should still work on any S939, S940 or CG stepping chip.

Download a64tweaker_V01.zip (Thanks to ragnarok for hosting this for me)

This first cut displays all the bit field values, including the reserved ones. At some point I would like to work out sensible names for each of these reserved settings so feel free to work out what they do.

Just remember this is a beta release, so I will be fixing up the know bugs and adding any features/setting that people feel are good. Just PM me or drop a note in this thread.

The above screen shot shows some good settings, but I am sure people will work out better ones.

Happy experimenting.

==============================================

Installation
--------------

1. Unzip the a64tweaker_V01.zip file to a directory.
2. Run a64tweaker.exe ... thats it

On the first run the proggie will setup the legacy IO drivers. This sometimes fails, but dont worry, just execute the program a second time.

Known Bugs
----------------

1. First execution may fail to load the IO driver.
Workaround: Run a second time.

2. Doesnt always load the registers values upon startup.
Workaround: Hit the refresh button.

3. No error checking what so ever.

thx Codered!!!

work fine here

On Chaintech ZNF-250 works fine.
Thx...

Been testing it on my ga-k8n pro and A64 3000 C0, works great so far.

Thanks very much Codered


EDIT: You definitly dersevered your sticky man, right on..............wrote this down here cause I didnt want to mess this thread up too much. Remeber people, dont mess up a sticky with a lots of spam.

[CodeRed]

Glad to hear its working on other rigs

Could you guys edit your posts with the type of CPu you have

C0/CG stepping
S754/S940/S939

Just want to make sure it work on all revisions of the A64. If it doesnt work on all revisions then I'll have to query the CPU ID and adjust some of the options.

K8N

Work excellently

[cpulloverclock]

excellent

what are the best timings and settings for

max asynch latency
read preamble
idle cycle limit
dynamic idle cycle counter

[cpulloverclock]

it works perfectly with a CG core

[pik-ard v1.1]

duronbird, what could you get before you used this?

by that, i mean max OC, ram timings, and super pi.

i just wanna know exactly how much this helps.

Wow this program kicks ass!!!!! Now it only needs an option to apply these settings every bootup

[cpulloverclock]

edit

ras to ras delay = reserved 001b = 1T
min ras active time = 0011b = 3T

I would like to save my settings with this prog..

lol... that is to much to ask for i think...
coz we need to save it on CMOS

CodeRed... excellent job.... congrats

CodeRed... try read the cmos data.. u can access it with 8 bit mechanism...

Address Port: 70h
Data Port: 71h

Yes, I was thinking about that too.

Next version will have a save/restore settings option. I will also make a simple console application that can restore settings at startup.


I will wait about a week before releasing the next version. That way all requests can be incorporated.

@tictac
What can I expect to find in the CMOS data .. will the contents be BIOS specific?

[tictac]

not sure either.... but i'm pretty sure they save the data in there
when we power off...

I tried tweak my cmos but ended with CMOS Checksum error...

Anyway if u can load it when windows boot up that will be nice to GL

[cpulloverclock]

cordered, u can do the same think for the I875/I865 chip?

I am not familiar with the 875/865 chipset registers. If you can supply me with the info then I can write another proggie for that ... testing might be a bit hard though since I dont own an intel board.

I could test on this ty DELL box that I have at work ... it needs some tweaking ... 2.4GHz that does superpi 1M in 1min13sec

what do u want exactly? I dont know any tweak

[HKPolice]

I doubt these kind of tweaks would yield much for a P4 setup since the northbridge is a bottleneck between the CPU and ram, therefore slightly tighter ram timings would barely even show up in benches.

Add to that the fact that P4's netburst architecture doesn't benefit from low latency ram as much as A64, and the overall gains will be next to nothing.

Of course, no one can be certain until they try

[HKPolice]

BTW, the 2T command rate doesn't seem to work with my C0 stepping A64... I try to enable it, and it just goes back to disable after pressing set. I don't think this is a bug with your program though since I tried modifying it with wcpredit before, and it did the same thing. Any reason for this?
