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 :banana:
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. :toast:
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.
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?
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 :banana::banana::banana::banana:ed it up.
Ok, thanks for the link :toast:
@digitalfrost
could you post your code (tweak.asm) that you used to patch the bios, i'm kind of confused
thanks
Not very elegant, but it works ;). Btw is this a chat or a forum :p:Code:pushad

That's the best timing for TCCD ?
nice modding :up:Quote:

keep up the awesome work :woot:
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?
@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 workQuote:

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?
exactly, i'm getting ocz rev.2 tcc5 later this week. DRR620 is coming :toast:
hi guys
will this timings burned into the BIOS help attain higher OC.... compared to setting it in A64 tweaker ????
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
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. :)
^^ if someone could apply those timings to a 1.3B6 bios it would be awesome :)
