Yes, but you may lose one core after the mod. I remember doing this mod on a PD945 and only 1 core showed up after the mod. You'll need to do an additional step to prevent the mobo from seeing the mod.

thanks......but i now realize the board i am gonna use (it's being deliverd this week) has some pretty good overclocking setting in the bios. i will probably save myself plenty of headaches just messing with the bios settings rather than risk damaging the cpu or board.

thanks anyway!

I has not posted in this thread in a bit so a bit of bsel moddery I have encountered over my last week.


Interesting thing, while putting together a new (and very, very, very, very (you get the idea)) PC I bought an ASrock G31M-S motherboard for a P4 520J togethor cost less than £30

I wasn't really considering a BSEL mod but something in the manual caught my eye, Asrock's OC jumpers. It first I though Asrock had brought another piece of history back but I was pleasantly surprised. What these jumpers do is like an automatic BSEL mod, just shorting a jumper on the board allowed a 800 fsb cpu to boot at 1066 with memory, pcie frequency and everything else at stock speeds.

Now you may be thinking that this is completely pointless yes, the motherboard (and most others) can do that through the bios. But what I find interesting about this is that someone with know overclocking knowledge can just short a jumper and get an instant overclock. Not only that, with something like this you can achive higher overclocks, as all other variables like memory and pcie speeds are as default even though your cpu is running at 1066 instead of 800. So its like a new starting point if your memory doesn't overclock too high. AND it yields all the advantages of a BSEL mod without having to fiddle around with connecting pins!

Very impressed with this feature and I think it should be implemented on more motherboards as its very useful.

This is the board if anyone got this far in the post:

Sorry if I've ruined your evening

I'm thinking about doing a BSEL mod to my e5200 since my computer is a hp, so no overclocking abilities. Would the BSEL mod work with my mobo? The mod is going to be for my sig rig. Would the mod be harmful to a cpu or mobo? Also could the mod be reversed if I used electrical tape?

Edit: Tried the mod with tinfoil and glue, failed wouldn't post. After putting the cpu into the socket the tinfoil moved. So i took out the tinfoil and the computer would then post and boot up. It's really hard to the the mod with tinfoil since it has to be so small D:.
I might try it again possibly... any other materials this mod can be done with? Dont have a Conductive Ink Pen

I can't find any definitive source of VID mod images. I swore I had some links and images saved before that showed a whole range of VID mods for the E2140/E2160/E2180 line, but now I can't find much.

Just over a year ago (or maybe two?), I had an E2180 that I kept around default speed, then I got an E2220 after convincing a family member to trade with me. I ended up getting some "Rear Window Defroster Repair Kit" from Advanced Auto Parts for $7 to mod it. I was able to take the chip from 2.4 GHz to 3.2 GHz (12x266).

However, shortly after that, I got a motherboard that supported VCore adjustments and a lot more control, all while being stable and not having to mess with pulling the chip over and over to "re-paint" it. I still ran at 3.2 GHz, but this time at 8x400. Of course, I had cleaned all the stuff off the chip to use the motherboard's controls.

Since then, I've been able to get a Q9550 for my main system (which I run at 3.2 GHz as well, 8x400). I traded the E2220 back to the family member and got my E2180 back.

I have the E2180 in my old ASRock 4CoreDual-SATA2 board again, and running at 2.0-2.1 GHz just wasn't any fun, especially since I know I could get it faster.

So, I decided to BSEL mod it again.

800 -> 1066 worked fine. I then looked for the VID mods. One I saw didn't work (it showed two horizontal lines, two sets of pins joined)
Then I saw an image that said it was for "1.20 to 1.40". It has two pins joined, and one covered. That one worked.

The thing is, I don't want to do 1.4v.

My chip seemed to default to around 1.15v on boot. It boots at 10x266 at that voltage, and seemed stable. I wanted to get it closer 1.2v or 1.25 (to help against vdroop, and to make sure it has enough juice). Not the 1.35-1.4v it boots at with the "1.4v" mod.

I can't find any images that show what pins to connect/cover to hit ~1.2v.

I've tried searching Google, but keep finding the same "1.40" and "1.45" images, and stuff for chips that default to 1.3v or something.

With the 1.4v mod, the chip hits 80C (stock Intel cooling) at 2.66GHz. With the default 1.15v, it hit around 68C or something.

Does anyone know how to get the E2180 to have a 1.2v or 1.25v VCore?

japan1

Don't know if there is a VID for such a low voltage, I havn't seen one anyway.

You could try one of these, although I'm not sure they'd work on your E2180.

Yes the mod should work, it can be done with tin foil but is very fiddly. Try get some conductive ink, defogger repair stuff etc.

All right, thanks to japan1, cas27 on post#134 and Imperious on guru3d forum.

Here is my story.
ECS G31T-M, E5200 Stock Cooler, OCZ ddr2-800 (555-15 2.1v)

The ECS g31t-m is a small mobo without any voltage adjustment. In bios, it shows, VDimm 1.872v, CPU VCore 1.120v. I can set the fsb to 250MHz stable. In system, SpeedFan shows, VCore 1.20v, VDimm 2.14v; CPU-Z shows, VCore 1.200v; the VID is 1.2250v.

(Even in bios VDimm is 1.872v, in system the real VDimm is 2.14v, which is good for my ram to run at 5-5-5-15. Such that I can manually set the timing to 5-5-5-15 in bios, otherwise, it would run at 6-6-6-18 if I let the timing Auto by SPD)

So, I need to set a higher VCore to go over at least 266MHz. Since the VID is 1.2250v, I choose to mod it to 1.325v as cas27's case. So, went to Fry's to get the circuitwritter pen, mod the vid to 1.325v, BSEL mod to 1066 as cas27's image. Right now, the system is running at 266x12.5=3325MHz stable. After mod, in BIOS, VCore 1.296v. In system, CPU-Z shows VCore 1.296v; SpeedFan shows VCore 1.30v, VDimm 2.14v.

And then I think the VCore is too high right now. (I don't think the CPU needs 1.296v to run at 3.3G.) Such that I remove the VID4 mod, then connect the VID3 & VID2 to Vss to produce a 1.3v. BIOS reads 1.264 VCore; in system, CPU-Z shows Vcore 1.264v... testing, should be stable....

Hey ;D love your guide, just need to clarify a few things before starting.

1. Would BSEL modding affect ram, i have a Dell Vostro 200. Its motherboard can only support 667mhz or 800mhz ram. Right now i am using 800mhz ram, bought after the computer.

2.Is it okay if i use Aluminium foil? I dont have a conductor pen and someone on another forum used it and said it worked good.
Thanks in advance.

awdrifter

1. It wouldn't effect the ram speed, after the mod the ram will automatically run on a lower divider (same speed).
2. I wouldn't risk it, the alu foil might move during the cooler installation and short out the wrong pin. I killed a Athlon XP from doing a pin mod a long time ago because the copper wire I used wasn't thin enough and it shorted out some of the neighboring pins.
