How to pinmod and further overclock the M11x R1 (SLG= Hardmod only)

[sk3tch]

That will get a little more performance and less battery.

Yeah, my main goal is to play BF:BC2 multiplayer with 30 fps. The R1 has some element of risk to that - i.e. if the OC does not work, etc. I hope the i5 can manage rock-solid 30 fps in MP. I can only find numbers for the i7.

For gaming the cpu difference between the 2 will be minimal....and they use the exact same GPU.

How would you go about extracting the .rom of the bios to look at it in an editor? It is just an exe package right now that does not extract before running. I ask because I am quite interested in altering the way that the bios handles the ram and OC stuff (eg it is very poorly done currently....)
I would like to see an OC Mode WITH speedstep and with the 1:2 ram ratio (in addition to support for higher cas ram)

In order to get at the .rom file you DL the version of the BIOS update you already have installed. (I'm going to assume A05) You run the installer and it'll extract itself to 'C:\Temp\Winphlash'. It'll try to run but since you already have that version installed the installer will just exit. It doesn't delete the extracted files so you can just get them from the directory above.

Unfortunately the file won't open in Phoenix BIOS editor.

the difference between a pinmodded core2duo and an i5 is somewhat minimal, but games that can utilize 4 threads you will see an improvement in fps with the i5. my i5 overclocked to 164, with a gpu overclock playing at 1080p on medium graphics i get about mid 30 fps with dips to 20 under mass dust, open fire, basically a worse case scenario with BFBC2 online play. make sure you use throttlestop.

I will try that, thanks!

Hopefully I will be able to figure something out with it

I'd like to see you be able to mod the bios to GM45/GS45 chipset sets and locks the ram ratio based on the running FSB. Worth perusing the chipset datasheet.

It would also be interesting to see how the BIOS is implementing the FSB jump in OC mode. May be the equivalent of the pin mods people are doing - but doable from BIOS

But I do not want to get any hopes up, will have to look around at it first.

Good idea. This mod is really aimed at the M11x R1 early adopters who are sick of their aging CPU.

I used TSBench as a benchmark since it can use all threads. A 2Ghz R1 gets 50s with 2 threads and an i5 166 TS (also 2Ghz...) gets 45s with 4 threads, both tested with 32M. 10% extra performance thanks to more threads and better architecture, not enough to make a mindblowing difference.

Looks like it does something with BSEL- it's always locked to 6x and .9v. I tried to reverse engineer 266mhz to 333mhz but didn't find anything of use in IDA Pro or even load the file in modbin6 (Yes, it's an Award bios editor, but seeing as Award and Phoenix merged for 13 years, it's worth a try).

Kizwan managed to load the BIOS but couldn't do anything since there was nothing useful that was hidden. I looked at reverse engineering the BIOS and failed. Perhaps someone who understands assembly language can step up.

TS bench is odd because i got 27 seconds on 32M on wPrime. what did you get on your 2ghz c2duo on wprime? Interested in the comparisons.

TSBench is not odd because it runs differently to WPrime. You'll find many different Pi benchmarks giving you different results from their coding. Try increasing priority on TSBench.
I couldn't get WPrime working on my R1 and as you know, I already got rid of it. I also had it terribly optimized- it was slower then some guy's 2Ghz R1 despite running at 2.07Ghz. I was using some guy's TSBench result anyway, so ask him for WPrime.
