The same old sh*t to start a new thread for 'wyt' ( 'wytiwx' ). :cool:
THX, man. I'm coming. :D
I think I love the old school overclocking things, the first step was Celeron D, now this is the second step.
LGA771 CPU for LGA775 Mobo mod is not my original thing, I just do this for interest, and I mean no offense.
We know that many LGA771 CPU s and LGA775 CPU s were made from same wafer.
They can have the same CPUID, same stepping, same cache size, same CPU Features, even same FSB and Freq, the only one different thing is Socket type.
So it's not so difficult for LGA771 CPU to work on LGA775 Mobo, right?
This is top view of two CPU.

Processor Land Coordinates

See? Most of Socket Pins are the same definitions, functions and positions.
That's the good news to mod work. :D
Next step is to check socket pin land assignment one by one.
There are about 76 different pins between LGA771 and LGA775, but many pins are 'RESERVED', 'TSETHI', 'COMP' and 'FCxx' pins, which can be ignored in many cases.
LGA775 socket have 8 pins more than LGA771 socket, these pins are Power pins, like VCC, VSS, VTT.
LGA771 socket have 4 pins more than LGA775 socket, these pins are Power pins too.
It doesn't matter for losing some Power pins.
According to someone's testing result, the most important pins are two address pins:

For LGA771 CPU, land name A3# is Execute BIST (Built-In Self Test), it's pin No. M5 on LGA771, but this A3# pin is pin No. L5 on LGA775.
So the key is to exchange pin M5 and L5. Thank God, pin M5 is adjacent to L5.
Get this done first!
You keep blowing my mind with these kind of things man...In before greatness :D
Old, but still charming. ;)Quote:

Third thing is to use software like CBROM (for Award BIOS) or MMTOOL (for AMI BIOS) to check your Mobo's BIOS, find if BIOS has the CPUID of LGA771 CPU.
In many cases, the Mobo already has many CPUID codes, I won't take my time to explain how to check and insert the CPUID codes.
You can get more info about LGA771 CPU in this website: http://www.cpu-world.com/
What am I waiting for? Nothing.
Go go go!

Wow you guys are going super hard on 775, pin modding and all.
I am sure the 771 cpus have to be pretty cheap nowadays.
I've seen refurbed 771 quad cores(E5405-5440) for 13-19.99 per chip. E5450-X5472's range from 40-100 per chip. I managed to snag a pair of used X5472's for $40 on eBay, but that was just a very lucky snag.Quote:

BTW: Did you end up having to mod the bios and add the CPUID's or did it just work?
Well since E5440s are dirt cheap on ebay(uk) I decided to get one to revive one of my GA-EP45-UD3P's for that ^^
Also L5240's are dirt cheap 9USD, 3Ghz, 1333fsb and 40W tdp. And which i also got here :D
Edit: btw X5272 which is 3.4GHz dualie is 14.90USD on ebay :hrhr:
Excellent Thread. I don't recall when was the last time that I saw something like this being done. I think that it is VERY useful due to the fact that you showed a proof-of-concept that such type of Socket mods can work. There are many CPU families that usually shares the very same die on many different platforms (Server, Desktop, Mobile), so from a BIOS perspective should be supported, assuming that someone figures out how to route the pins and a physical way to attach it to the Socket if it doesn't fit and mount the Heatsink over it.

I didn't mod the BIOS, just update BIOS to latest version.
But for some 771 Xeon with 45nm and E0 stepping, like X5260 E0 and E5450 E0, maybe need BIOS mod to insert some codes, or you may lose some CPU features like SSE4.1, VT-x.

I have a more crazy idea to mod 478 Socket M/P to LGA775... but that's really really difficult for me :(

Something like this?
Yep, wish I could make something like this.Quote:

Now if you could separate the BCLK from the PCI Buss or unlock the multi's on my E5-2687W's I'd be one hell of a happy camper!:DQuote:

Used PTCA-01 478 CPU transfer for LGA 775 Mobo, and Thermalright True Spirit 120M on air with long mounting screws.
CPU transfer with VID pinmod, because VID7 and VID6 pin are undefined in Socket 478, which will confuse mobo VRM and fail to change Vcore.

can you run a northwood, and lower FSB p4 (100, 133) on a p35 and higher MB with the adapter?

For EP35-DS4, 133 FSB works fine, need no mod. 100 FSB may need FSB mod I think, due to MCH strap. not test yet.
But CPU will get high Freq after FSB mod, so use a low ratio chip makes work easier.
Someone should try Xeon X5470 on a decent board with decent cooling :D 10x multi.
Finally can make some xtreme cooling.

wytiwx, hello my friend. I have followed your mods very carefully and admire your work. However, I am a little bit confused. in your picture description of your mode I see you taking aluminum foil and sticking it to lands K5 and L5. For what exactly is the purpose of doing that? What is that doing? Now further in looking at the pictures it looks like you are shorting K5 and L5 together? That is the best I can make from your pictures, as the aluminum foil does not extend in any direction beyond those two lands. If that is the case, why do you just not use a single strip of foil joining the two? Clearly you are not insulating those lands so what are you accomplishing by what you are doing? The other thing I noticed was in your previous discussion in the thread you are talking about modding lands L5 and M5. However in the pictures your mods are to lands K5 and L5. I'm confused.
Also in your next post you are showing a CPU-ID readout for a Dempsey 5050. Now my understanding is that BSel mods are adjusting the native FSB of the CPU to a higher FSB and getting a higher frequency as a result. Now the Dempsey 5050 has a native FSB of 667. Your readout shows you achieving 4.283 Ghz. In order to do that you would have to accomplish an FSB bump of 952.5 Mhz to use the native multiplier. Did you use some kind of software on the motherboard to alter the multiplier? BSel mods are supposedly a means to boost your clock speed without software intervention. I can understand the physical changes made to the LGA 775 socket to accept the LGA 771 as the tab cutouts are different. Beyond that you have lost me. What you are doing is either incomplete information or not what a BSel mod is supposed to be doing. BSel mods normally involve H30, G30 and G29. Please explain. Thanks for you time.
wytiwx, hello again my friend. Forgive my dumbness, I am new at this and still trying to figure out what is going on. I am stuck with working with an old Foxconn motherboard which does not have bios support for overclocking. So in order to achieve any kind of "boost" in performance I have to do a BSel mod and adjust the native FSB of the CPU to a higher rate and let the native multiplier do the rest. Maybe you could explain something to me. In making these adjustments, what you are doing essentially is creating the right combination of high and low lands to achieve certain FSB speeds. My understanding is the land environment is by default "high" (represented by the "1") and has to be "pulled low" (represented by the "0"). Again my understanding of how this works is if you have a "0"(low) that you want to keep high (1) you merely have to apply some insulation to the land so the land cannot be "pulled low". Is that correct? Now if you desire the inverse, you have a land that is "high" (1) and you want to pull it low(0) how would you accomplish that? My inclination would be to short it to another land that is pulled low and thereby share that "pulling low" with that land. Or possibly to some other land that is a universal ground or has some other faculty that will pull it low at the appropriate time, (which land that would be I don't know) Please explain if you can. Thanks
Me again. Also above I see a motherboard with what looks like is covered with mud. and a CPU with some kind of cooling device mounted on it. What is up with that? Can I assume the "mud" is some kind of heat conductive material that cools the board with better heat dissipation?
very geniusss n creative...:clap:
