PLL Pinmod Overclocking Methods and Examples

[TomFly]

Hi moral_hazard,
hi nando4,

I think, modding the fsb with wire (bsel+pin57 = pin64 on my pll) wont boot the system because a +66 from 200->266 ist to high. I guess my ddr2 800 and cpu cant handle that. I hoped to reach 250 with setfsb.

Sorry, I'm not a linux enthusiast. I know grub from my M$ WAIK preinstalled environment recovery cds - thats all. But your suggestion reminds me to think about OS power management access.

Is it possible, the crash depends on some sort of speedstep; superfetch; energy management. Should I try "safe mode"?

I mailed Abo one week ago. No response.

Bye

Your CPU will probably be stable.
I did overclock from 200mhz FSB to 272mhz and my CPU was fine, my ram was unstable though.

You can use thaiphoon burner to flash the ram to a lower frequency, so it will be stable.

I think you should try a 266mhz fsb.

Hi moral hazard,

does the fsb influense the RAM/FSB divider so I do not need DDR2 PC8500 1066MHz?
1:2 mean 200:400(DDR800) / 266:533(DDR1066)
2:3 mean 266:400(DDR800)

I understand, a BSEL-trick w/o FSB_TEST_MODE-pin modding results in a lock at lowest multi. If I have no time to do the BSEL-trick (the pll lies very good accessable below the keyboard, but the socket is on the bottom of the mainboard), is it enough to do the PIN64 modding or must be the two frequencies identical.

Do not do the BSEL mod.


Just modify the PLL.
If your memory becomes unstable, then download thaiphoon burner and lower the frequency of the ram. I can help you with that.
I suggest lowering the ram frequency before you pin mod the PLL.

Hi moral hazard,

thaiphoon burner. Never heared about it before. Does it change MHz or CAS latency? I apprechiate every info relating this topic.

Return to start:
- if the setfsb-version doesnt work because of SATA=PLL2
- if Abo is not responding my ICS9LPRS355B.K.L inquiry
- if the PIN64-version needs to much knowledge about SPD flashing
I will keep my hands off and do the undervolt procedure.

Bye

Ok.

Thaiphoon burner lets you change anything, MHz and latency (even voltage, but DO NOT CHANGE THE VOLTAGE).

Please be careful with thaiphoon burner. I will give you instructions if you need them.
You should only flash one stick. DO NOT FLASH BOTH STICKS OF RAM.

When you lower the frequency of one stick, the other stick will also run at the lower frequency so you do not have to flash it.
Same goes for the latency.

Make sure you leave one stick of ram alone. It is very important, it will let you fix your ram if you do a bad flash.

It's not too hard.

Hi moral hazard,

seams you are online 24/7 {8-))
If the SATA=PLL2 problem is not resolvable today evening (pics follow) I will give the 200@266 mod a last try. Before, I would like to know your volt/temp scores with prime or orthos or OTTC.

Actually with my mods...
1.) extend fan suckhole to 50x50mm from the default 25x50mm
2.) 0,9750Vc@2000
3.) acrtic silver 5 instead of the default compound
...I only achieve 51°C in coretemp during gaming
(with HD4650 heating up the heatpipe 78°C additionally)

Bye

Hi moral hazard,

here are the pics of 3x crashes.
It is PAL only 720x576, and I cant see something helpful.
I worked keyframe accurate. 1sec is only made of 25frames,
so I cant catch the needed 0,0000001sec.

Hi moral hazard,

myself - once again this evening ;-)

I try changing the byte "0"...
0100001=41 to
0100011=43 SATA=PLL2 - everything is fine
0100101=45 SRC_Main=PLL3 - exactly same crash like set fsb
0100111=47 SATA+SRC - exactly same crash like set fsb

So I think we have to look for PLL3. Btw if it is not inconvinient
to you, please post me the DDR2 SPD flash procedure.

Bye
Tom

Download thaiphoon burner here:
http://jungle.at.tut.by/download.html

Start the program.
Click on "Read".
Read the SPD from one stick of ram.
Then click "Save".
Save the SPD image (this will be used as a backup).

Now click on "Editor".
Here you can change the frequency.
Lower the frequency.
Then use the Editor to flash the new SPD onto one stick of ram.

Then restart the notebook.
Use CPUz to check if your memory is running at the frequency that you set.

If you have a problem, take out the stick of ram that you have flashed.

Only flash one stick.

I can give you screenshots if you need them.
