I dont think that regular pencil will work, but you can try.

Try using tinfoil and glue. Worked for me.

hey bro i jus did dis mod but not in d proper way.
I got a thin piece of wire and den glued it to the stated areas to get from 800 to 1066 mhz but i didnt get successful coz after dat ma pc wud start but nothin wud apear on d screen so i jus removed d wire and nw everytin is ok. So wat u think will dis be d case even if i use a copper/alluminum tape/ conductive pen?

The wire could have easily slipped when you put the processor back in its socket, did you try resetting the bios before putting the processor back?

Hmmmm y do u reset the bios and i shud do it buy removin d jumperS?

I don't think the fsb mod can apply to any Gigabyte mb, except ones that use 945 chipset!?

GB boards are pretty hit & miss with the mod.

I think it words on all 945 boards, P31 and G31 boards. But don't quote me on that.

Check your MB manual.

Okay, let me start by saying great guide!

I've so far read the first 11 pages of this thread, and have yet to have my questions answered entirely.

I'll start with the basics:

1. Once you determine what the voltage of your CPU is, and the new voltage you are trying to achieve via page 15 and 43 of this PDF http://download.intel.com/design/pro...hts/320467.pdf , what do you do to change a 1 to a 0, and a 0 to a 1? Which needs to be simply covered/insulated, and which needs to be connected to a VCC?

1. a) Will connecting the required pin to a VCC be the ONLY option available for the corresponding 1>0 or 0>1 change? Does the VCC have to be right beside it?

2. I have 800Mhz ram in my mobo - the ASUS P5KPL-VM. It allows me to choose a 800mhz or a 667 mhz setting in the bios that will change the divider from 1:2 to 3:5 respectively. My motherboard does have a manual FSB adjustment, which I have been using to overclock my E5200 (3.25Ghz stable max.) Will doing either the 800=>1066 or 800=>1333(possible?) help in keeping the frequency of the memory down and resultantly raise the frequency of the CPU? The reason I ask this is because I rather hit the limit of my CPU before the limit of my DDR2-800 ram. Or will it simply have the same effect as raising the FSB in the bios with one of the 667 or 800mhz profiles?

3. In trying to determine the correct VID of my processor, the reading from CoreTemp fluctuates according to the level of stress with the processor. I understand that this is due to Intel Speedstep technology. You have mentioned that
-Intel speedstep
-C1E
-EIST
must be disabled in the bios for it to remain a constant.

3a) Do all 3 of these things need to be found and disabled in order to disable speedstep, or will one suffice?

3b) I like the idea of saving power, and would prefer to have speedstep enabled. The VID of the CPU changes between these 3 values with speedstep enabled: 1.1000V (idle) and fluctuates between 1.2875V and 1.2250V when under stress. Which of these 3 values will I use in determining the correct pins that need to be modded? Do I perhaps need to disable speedstep in bios to get the correct value, and if I do, will I be able to re-enable speedstep after the pin-mod to save power? Will the vid-mod be affected in any way?

4. I have the new R0 stepping of the E5200, which isn't officially supported by my motherboard. My motherboard only officially supports M0. The latest bios update was release 4 months prior to the release of my E5200 revision, and there are no updates planned. CPU-Z fully detects this as R0.

a) Will the VID, and 800>1066/1333 pins be the same as in the PDF that I linked to above?

b) (slightly off topic, not urgent) Are there any features that the new CPU revision is supposed to bring that won't work due to no bios support? Are there any other problems that I may foresee because of this at all?

Thank you VERY much for all the time and effort you have put into this thread,
keep modding!

1. take a look at this, cas27 connected vid4 to vss, so vss connceted to vid4 gives 1.3v. hope that helps.

1a. vcc doesn't have to be right beside it

2. doing the fsb mod changes the 'default' speed of the cpu, so all other variables are also stock so your memory will be at stock speeds

3a if those things are in your bios, they should be disabled when your doing the mods (it avoids confusion). some bioses have 1, some have 3 just disable which ones apply to your bios.

3b. after you've done the mod its fine to re-enable them all, on every board i've tried it works fine dropping the multiplyer and vcore while remaining stable. like said before the mod will change the default vcore so the motherboard just treats it as a cpu with higher vcore and drops the voltage correspondingly.

4a. yes, somewhere in this thread someone did the mods on an e5200

4b. shouldn't be a problem, just get the new R0 bios when its released or contact asus to try and get them to make you a bios (works for MSI)

sorry about the somewhat unstructured response i'm oddly tired

Thanks for the quick reply!

Okay so let me get this straight, to turn a 1 to a 0, you need to connect the corresponding pin to a VSS, and to turn a 0 to a 1, you simply need to cover it with a piece of tape (insulate it).

I've also found C1E and SpeedStep in my bios, and disabled them both. I couldn't find EIST, is it possible that it goes by a different name?

So now, my voltage doesn't fluctuate, but I'm confused as to which is the correct voltage to start from.

The idle Core Voltage that CPU-Z reports is 1.328V, it fluctuates to 1.304V sometimes as well, but generally stays at 1.328V. Core Temp gives a VID of 1.2875V. At Load CPU-Z voltage drops to 1.280V and fluctuates between that and 1.272V, eventually staying most of the time at 1.272V. Core Temp VID stays 1.2875V.What really throws me off though, is that the BIOS reports the voltage as 1.312V. Which one of these should I use as a reference to determine which points I must insulate/connect?

Thanks for all the info!

hi there.

does anyone know if the BSEL mod will work on a socket 775 Intel Pentium D925cpu.

i wanna go from 800fsb to 1066fsb.

mobo is a asus P5N7A-VM
