WPCREDIT tweaks for the A64

[Th3__W00T_GuY__]

my sys is always freezing if i press SET ?! but if i change memclock mode to 166 mhz (in bios!) it works!

Is your RAM's actually able to do what you want them to do?

I cant get this setting to change to 133:


Any ideas?

Running 4 x 1gig pc2700 chips in dual channel NUMA, ECC off
Dual opteron 250s

u should b able to change it in the bios under the memory settings...? unless ur mobo doesnt support that?

[ZxCs]

Mobo is a workstation/server one (Iwill DK8N) so it doesn't support memory divider settings, its main reason I'm using a64 tweaker. I have also tried lowering my HT and trying it but it still freezes when I try and set it to 133. Funnily enough it WILL go to 100 and not freeze, but it is not reported in CPU-Z and clockgen.(Overclocking still seems too stress memory at 100 setting)

You can check whether you have interleave enable or disable this way

I have an Asus A8N-SLI and it seems every time I flash a new BIOS A64 stops working, the settings are all messed up (not correct) and nothing happens when I try to 'set' something different.

I already formatted twice because of this problem aaargh. Now I just got a new BIOS and it happened again.

Hi all,

How do I change the dividers and hence the memory speed using this programme? On the board Bios lets me use 200 or 166 does this tweaker have any speeds inbetween which will mean I can get the best out of my CPU and memory?

Thanks for any help you can give me.

Great find TicTac! Hope you and Red can get that into the next version.

Hi!
I tried the A64Tweaker yesterday. First time it worked perfectly, but I set one value a bit too low and my machine rebooted. After reboot I fired up the tweaker again, and now it just shows (as it seems to me) random numbers.
Lots of reserved values and way too high numbers. I've tried re-extracting the tweaker, and on different hard-drives, but it won't work. Changig a value to something I know is right and hitting set resets the value to sh*t.
What's wrong?

My hardware is:
MSI K8N Neo2 nForce3 Ultra s939
AMD Athlon64 3000+ winchester
OCZ PC3200EL Dual rev.2

Running this at 272x9, 1,7V, 2,5-5-5-5. 100% stable.

delete the following registry key & A64 Tweaker
HKLM\SYSTEM\CurrentControlSet\Services\cpuz

then reboot and re-install A64 Tweaker.

It should be fine after that

[maedox]

Thanks! I actually read this whole post a few weeks ago, so i knew there were some reg-key I should delete. Couldn't find any relevant keys with words codered or a64tweaker, and then it was cpuz.

Works fine now and looks like this:

It's so hard to know what settings do what, so do you have some good tips for me?
I have to have a little relaxed settings to keep the high clock.

[likwit]

Thanks codered, I had the same problem all the time everytime I had it I reinstalled Windows LOL. This is a better solution

good info

If u dont want to use WPCREDIT u can built isa rom and embended it into biosfilewith cbrom... build a rom with:

header: 55 AA  ; Boot Able rom
jmp init ; jump to code intialization
retf ; return far to system bios file

INIT
pushad  
push eax
push edx
mov eax,0x80002184; eax=Bus0Dev2Func1,Offset 84,85,86,87
mov dx,0cf8 ; set dx as adress port
out dx,eax ; send the address to IO Space throgh dx port
mov dx,0cfc ; set dx as data port
in eax,dx ;Receive the data into eax for the address we sent through dx port
and eax,XXXXXX ; Change the data
or eax,XXXXXX ; Change the data
out eax,dx ; Send back the modded data through dx port
pop edx,
pop eax
popad
ret ; return to header

last bit; use 8 bit checksum

then install it with cbrom
cbrombiosname.bun /isa filename.bin

cheers

tictac,

would you be so kind and tell something more about this? i would like to build my custom isa option rom and include it into the bios image, but i have a few questions. Which utility to program in do you use to build these option roms? I need to change the Bypass Max, located at offset 0x93h, bit 1-3 to 111 (or 7x) and the max async latency located at offset 0x94h bit 0-3 set to 1000 (8ns). I need that to include into BIOS cause else i can't run 7-3-3-2.5 timings on TCCD. If I use A64tweaker and set that at startup together with reconfiguration of timings from 8-4-4-3 to 7-3-3-2.5, it freezes. It doesn't freeze if i first set those two parameters and then edit the timings, but i must do that every time windows boots up, so I guess it would be a solution, to set those two in the isa option rom (i could set agressive timings in BIOS then too i think).

please answer tictac, i was searching the net for how to program isa option rom but i didn't find anything.

Compile it with Masm

@echo off
ml /AT %1.asm /Fe %1.bin /link /TINY

that was fast

and where do i set the data bits, i want to? is this the XXXXXXXX value in your code?

what's the last line of your code (last bit) - do i have to replace it with cheksum or leave it as it is?

here is example of my ISA rom source code... i use it on my NF7S modded bios

You just need to change the address & data for your patch ( i bold it on my source code

Good luck

thank you tictac

helps a lot

cheers

[shadowing]

Is there anyone that can get me this prog.? Apparently, i can't download it from either of the two links that Codered has. It says that it isn't there. Thx.

Thx. What are some usual tweaks that can help speed my system?

[TheMeatFrog]

Check out the screen shot I provided. RAM is in 2x512 dual channel running at 250MHz and I can't get the value in red set to 1 w/o lock up. Any ideas? Also any other changes to help improve performace would be greatly appreciated!

[shadowing]

Are those tweaks good for a S754?
