FSB downclock mod on the intel GL960 and GL40 --- useful info for PLL Modders

[RickiBerlin]

Now I am gonna get a bit out of topic, but Ricki, can you tell us exactly the steps needed to run a QX9300 on a PM965? even if it utilizies just one core I bet it outperforms X9100.. is any special bios/mod involved or it just runs after having done the BSEL mod? thanks

I can only speak for my system. (HDX Dragon with PM965)

Besides the "SocketMod 266zu200 266zu166 or" there are no further conditions. (I did everything described here exactly)

And still is "QX9300 or Q9200" recognized only for every "one hundredth motherboard start". That means "99x motherboard start" without success.

For a successful "OS boot" the system must first be limited to "working with a core." (in Windows using "msconfig" / when using Knoppix "acpi = off")

"QX9300" corresponds to 2x X9100 "(with four cores working)
With a core "QX9300" is equivalent to a half "X9100".

You see, with a core makes "QX9300" no sense.

@naton (or other users)

Can you confirm the "1066 CPU" will not work on 133MHz?
I have not googled. Maybe you had the test before.
For me, not a function "X9100" or "QX9300" with "BSEL0 VCC".
(of course also not "BSEL0 VSS" because that is "not a mod for this CPU" )

CPU remains in each case at 266MHz. Not possible to boot PM965.

And one more question:

But first a few preliminary remarks.

At the beginning of this paper I describe the conditions when "QX9300" works on my system with one core.

Are all these conditions, then works "QX9300" perfectly normal "1 core".

That is, normal temperature normal overclocking with "ThrottleStop". No problems. (see pictures)

But, and here's one not explainable mystery for me:

As soon as I would like to adjust with the help of "ThrottleStop" a voltage of more than 1.3000 V, there is an immediate crash. No matter what the multiplier.

Why?

Normally a "voltage up to 1.5 V" be possible. At the "X9100" is not a problem. This also works with 1.5 V.

Read the ENTIRE thread. Great stuff.

I see you have figured the CPU socket can be disassembled.
You guys have made a lot of progress so far. A few questions...

have there been any Acer pm965 bios break throughs as far as adding c2q micro codes and apic with the recent progress of NetRollers 9600m gt bios fixes?

How do you keep the bsel from spreading apart contacts?

How do you keep the Bsel routed in such a way that it doesn't touch other pins when the cpu is clamped down?

Could you please post those links about acer pm965 discoveries around micro code and apic. I have prepared already a bios version with quad core information for ricki but it didn't help. I think and it was said already that apic probably has to be changed to support q2d. Unfortunately I don't know how to locate APIC information in HDX bios and also I would need information how to find it in another pm965 laptop which has such support. What is concerning netroller 3D I have asked him to made a fix to our vbios to support FX3700/280m video cards but after few replies he is not longer responding to my pm's Is someone able to talk to him and ask for further work?

I think if it was just a bios related issue it would be able to run without any problem on two cores.. however, according to Ricki it doesn't and therefore I doubt whether it's just a microcode/apic/you_name_it bios issue.

C2Q is a retrofit it into a PM965 system, running at a slower 800Mhz FSB. They are officially supported only in Series-4 chipsets (PM45/GM45) so look to those systems for a bios with the APIC/ACPI with C2Q initialisation code (eg: HP 8530W, 8730W).

Thank you for your clarification!
I thought this would be "AlphaHex" known. I wrote this but also on several occasions.
If it were otherwise, then would my purchase of "QX9300 and" Q9200 "not as a high risk.

PM965 is "gennerell" not for "quad" is specified. And I also have not found anyone worldwide of a "Quad" on "PM965" put to work successfully.
Exactly that's the biggest problem. Even if all conditions are (ACPI bios etc) mastered the question still remains .... can PM965 with "Quad" work?

I think yes.

What do you think of the 1.3-V problem?

I know that already but need help with those bioses. When you decompress them with phoenix mod tool you will get few dozen of files. I need information about GUID for DSDT and APIC to be able to work further on them.

But, i believe it was ricki who did a get c2q to run on 2 cores on his hdx. I saw this going through this very thread.

i was just referring to the 9600m gt thread netroller made.as far as bioses you can dl them from acer unless you need it extracted/copied from the computer witch i may be able to help with.

you guys should do some googling about bios modding there are some communities out there that do bit of bios modding. they may be able to help.

[cdoublejj]

I'd also like to add that you guys are really close to some break throughs hell getting that quad core to boot a pm965 already is a break through.

I really dig this kind of stuff essentialy we are learning what the heck makes the chip sets so different.... kind of if a pm965 can boot a quad and possibly run all 4 cores with the correct APIC and Micro codes what would make them so different from chip sets that officially support quads except an FSB clock incompatibility?

THINK ABOUT ALL THE THINGS!


Seriously, think about all the things... ever...in existence. It seems almost every day I learn something or teach/learn something by my self by just pondering and going over all the information i have absorbed weather it be some weird problem with a desktop i'm tinkering on or just coming up with some convoluted idea of technical nature.

Think about all the results you have gained so far, ALL the results weather it's screen caps or beep codes or damaged CPU socket. Then think about related things like netrollers bios mod thread, or even bios modding guides. Just let it all float through your head. Trust me you will come up with some ideas and answers.

Today I have a picture with all the differences created (see Spoiler! ). The image is very large, so please also scroll to the right!

Only then did I realize a "Bios Mod" alone can not help.
Even with "PM45" there are "Quad Support" and "not Quad-support". "PM45 not Quad support " corresponds to "PM965". (apart from 1066MHz to 800MHz)

Spoiler :

Here the same picture for smaller monitors. (slightly blurred)

Spoiler :

A subsequent search in the "WEB" was an immediate hit.
For example, "Aspire 8930G" with PM45. There are several motherboard designs:

1."MB.ASZ0B.001 - MAIN BD AS8930G.PM45.ICH9 LF" - only for C2D

2."MB.ASZ0B.004 - MAIN BD.PM45.ICH9.DIS.LF.QC" - for C2Q (even C2D?)

--------------------------------------------------------------------------------------

I'll try the "Blue + Red Pins" to isolate. Only for experimental purposes for two functioning cores. Further tests arise from my picture.
