MSI Neo2 Platinum simple request

**Blinkme323** · 06-20-2005, 07:07 AM

Hi, I need a modded Neo2 Platinum bios. Tictac or Bigtoe, could you help me out here. I am looking for this:

- Read Write Queue Bypass = 16x
- Bypass Max = 7x
- Idle Cycle Limit = 256 clks
- TRC= 13
- TRFC= 18

Those timings really don't affect performance at all and are the only ones that allow me to reach 270x9. I would prefer it to be done in bios 1.8 since it is the most stable for me. Some minor interface tweaks and the hidden options shown would be fine. Thanks for the help.

Here

At this point i wanna say a huge thanks to tictac, I was not able to get his sourcecode to work, but it made creating this patch alot easier and got me interested in doing stuff like this.

Tested and working fine on my machine. Note that you can not disable this in BIOS, so try these settings with A64Tweaker before flashing to make sure its stable.

Thank you very much. I will try it now.

**Blinkme323** · 06-20-2005, 06:55 PM

Best bios I ever used. Highly recommended. Thank you digitalfrost; great work.

@digitalfrost

apply your patch to 18r2

Thank you

btw, can you tell how you patched that BIOS?

**digitalfrost** · 06-20-2005, 08:18 PM

I won't patch 18R2 without tictac's permission, also tictac could easily patch the bios himself and upload it. (With the ability to disable the patch in BIOS by using NIC rom, I haven't gotten this to work...)
Read http://overclockers.com/tips905/, take a look at the sourcecode tictac provided, and read some assembler tutorials.
If you really wanna try this be careful, I had to hotflash my bios twice because I

ed it up.

Ok, thanks for the link

**nfm** · 06-20-2005, 09:00 PM

@digitalfrost

could you post your code (tweak.asm) that you used to patch the bios, i'm kind of confused

thanks

**digitalfrost** · 06-20-2005, 09:04 PM

Code:

pushad
;trc13
mov eax,	0x8000C288
mov dx,0xcf8
out dx,eax
mov dx,0xcfc
in eax,dx
and eax,	0xFFFFFF0F
or eax,		0x00000060
out dx,eax
;trfc18
mov eax,	0x8000C288
mov dx,0xcf8
out dx,eax
mov dx,0xcfc
in eax,dx
and eax,	0xFFFFF0FF
or eax,		0x00000900
out dx,eax
;Bypass Max 7x
mov eax,	0x8000C290
mov dx,0xcf8
out dx,eax
mov dx,0xcfc
in eax,dx
and eax,	0xF1FFFFFF
or eax,		0x0E000000
out dx,eax
;Read/Write Qued Bypass 16x
mov eax,	0x8000C290
mov dx,0xcf8
out dx,eax
mov dx,0xcfc
in eax,dx
and eax,	0xFFFF3FFF
or eax,		0x0000C000
out dx,eax
;idle cycle limit 256 clocks
mov eax,	0x8000C294
mov dx,0xcf8
out dx,eax
mov dx,0xcfc
in eax,dx
and eax,	0xFFF8FFFF
or eax,		0x00070000
out dx,eax
popad
ret

Not very elegant, but it works

. Btw is this a chat or a forum

**Jeager** · 06-21-2005, 09:50 AM

That's the best timing for TCCD ?

nice modding

feel free to patch or mod my modded bios... no hard feeling

keep up the awesome work

This is sweet, great to see people still working on the good old neo2.
Is that file the bios it's self or do I have to patch it onto a bios of my choosing or something?

**nfm** · 06-21-2005, 07:42 PM

@tictac
I requested those optimization in other thread. Can you apply that patch to your 18r2. thanks

@Jeager

oh yeah, definitely best bios for tccd. I will look for more memory optimizations

That's what happens when there's no money for new board. BIOS is already patched. Grab next release (Rev.3 of tictat's) if tictac will be willing to patch 18r2 or if digitalfrost will get it to work

**4rory** · 06-21-2005, 08:07 PM

Nice this is perfect might help me greatly with my rev.2 tcc5 overclocking are all memory settings able to bet writien into the bios?

**nfm** · 06-21-2005, 08:18 PM

exactly, i'm getting ocz rev.2 tcc5 later this week. DRR620 is coming

**harpyboy** · 06-21-2005, 08:59 PM

hi guys

will this timings burned into the BIOS help attain higher OC.... compared to setting it in A64 tweaker ????

**digitalfrost** · 06-21-2005, 09:13 PM

No they won't but they help if you have trouble to even boot windows at certian settings for example. Besides this, I boot Linux from time to time, and there is no A64Tweaker :o

**CD 1986** · 06-22-2005, 08:31 AM

Below is a screenshot of the settings which help me attain higher memory speeds without performance loss (1:1 ratio). Has anyone found any settings that greatly differ drom these to get better stability? If someone could take an original 1.8 bios and patch it with timings similar to these, we could have an even better bios than we have already. Things such as higher async latency help a lot i find, but don't give a big performance hit.

Basically im asking for an extension of the settings that Blinkme123 has asked for! Plus, some feedback for what are considered to be the best generic TCCD timings.
