For those using the e4300 that have reached a FSB "wall"

I was wondering if changing the FSB strap to 1066 on the CPU side could maybe help in overcoming the FSB "wall" that many seem to be hitting.

For those with nice mobo's, could you try this mod to see if it helps in raising your maximum FSB?

Materials needed:

-Car Defogger Repair kit --> I used the Permatex Brand from the auto store
* Silver conductive pen will NOT work *
-Steady hands

BSEL1 to VSS connection

Here is how it would look like:

Thank to all in advance,

PS - reason I cannot reap its potential benefits is due to my Asrock 775 VSTA, which struggles to go higher than 300FSB anyway.

Why silver is not working?

Don't really know the science behind it, but people who have tried the e4300 BSEL mod have not had success with the silver pens.

Do you own the e4300? If so how about giving it a go?

i think i might try that out with my e4300 thats laying around on my desk.

I've gotten both silver and copper to work, although I currently ran out of both. I think the major problem is just making sure the interface is clean is number one. Also you need to wait a while for it to dry vs. other times with conductive ink where there's nothing to push against it. In the case of this, when you sit in back in the lga, if it's not dry it can push the ink around the pin and if the interface isn't clean, it may be too insulated for the land to make good enough contact with the ink.

I usually go with copper since walmart has it way cheaper than autozone (although they've been oos :() and use a toothpick or pin (pin is better since wood absorbs and wastes some copper unless you reuse the same toothpick every time)

Make sure to post back with your findings before and after the BSEL mod xtrempinoy.

Great input ziddey:
You are probably correct in that the silver might have failed due to a dirty contact, but the defogger kit seemed more consistent and that is why it was suggested.

So did you actually try the BSEL mod on your e4300 then? Did you get better results?

I have an e6400 that I fiddled around with it with, so I was setting for 333fsb. Didn't really compare much though when I did it since the ds3's newest bios update allows 333's to be recognized but boot at 266 on non33 boards. Never bothered with the asus yet since my ram is being rma'ed and I figure I'd want to keep my 1066strap right now until new ram gets in

No I do not have e4300 but I have 6300/6400 Ill try with 6300 ;).

I have a E4300 that i am willing to try it on, but i couldn't find any conductive paint here locally anywhere. I will try to find a car defogger repair kit in the next week or so.

There is allready an topic about that :

That topic is regarding the native 1066 C2Ds to 1333, and this thread was started to see the gains of the 1066 for Allendale's. I see how you can connect the two, but the thread you posted was on the topic to see if the mod would work (we know now the mod works), but what I want to know is what other gains come from the modification of the 1066 mod for the Allendales.

If only I could afford a better mobo and ram, I would not need to have others chime :(

Keep the posts coming!

If your e4300 is hitting a wall at 220+ (no post), the pin mod will allow you to go 266+. :toast:

sorry im new here and im looking for ways to max out my e4300.. what is this mod and whats it supposed to and what are the benefits of it.. i dont under stand hitting a wall at 220+ i have booted mine at 406 so could someone please explain in the mean time ill be reading the other thread as well thats link in this thread thanks

Basically the BSEL1 connected to VSS will "tell" the motherboard that the e4300 is a stock 1066FSB CPU, thus boot at 2.4GHz with the 266MHz FSB strap.

What I want to know is if, for instance in your case, you can only reach a maximum of 406MHz FSB, will the BSEL mod increase your maximum bus?

I want to find out if the 266MHz strap is looser than the 200MHz, hence the FSB "wall" that some are talking about.

Kunaak recieved gains to his FSB going from 266MHz strap to 333MHz, and I am assumming that the 1333Mz strap is even looser than the 266MHz strap.

You would be the best candidate for this test of theory :D

Hope that is understandable,

I've tried using conductive silver paint that I bought off ebay, tried it several times and it didn't work even after letting it dry for 30 mins.

Don't really wonna spend more money on a £15 defogger repair kit (cheapest I could find).

here is what you were looking for someone who did the mod with an e4300

hey guys, i dont post much around here but i wanna say thanks for the pic for doing this mod, i used it with my setup, a biostar 965pt, E4300 (week 40A) and my machIIgt, and cellshock's

originally i couldnt get past 400x9 stable with my mobo, 405x9 would crash, so i did the mod and it worked great, read it in auto at 266x9, oced straight up to 445x9 with 1.55vcore to the chip

its currently running orthos at 441x9 with 1.55vcore, i think its just allowing the strap to change from whatever it was using for original speed of 200x9 and which this mobo wasnt allowing it to do

thanks again

Great !!! One question, you're using Conductive Pen or Defogger ?? And if you using Defogger, it's a Permatex Electrically Conductive Rear Window Defogger Tab Adhesive ? Or Permatex Rear Window Defogger Grid Repair Kit ? I did try with Conductive pen, and it's not working.

you'll want the repair kit that comes with a tiny bottle of copper ink. really not cost effective anymore. I used to be able to get them for $3.99. I checked again a month ago and the same thing is $15.99 now?!?

Like this ? http://www.permatex.com/products/aut...Repair_Kit.htm

It's not availabe in my country :confused: but the Adhesive Tab is available, i can't using it, right ?

yeah i used the little copper vile stuff that comes with the kit, the stuff used for repairing the lines on the window, it was $12 i believe, works great just make sure you let it dry, i gave mine about 30 minutes

heres a screeny of 4.0ghz and a 32m run

Hmm, well if you have a specialty electronics store, they should sell both conductive ink pens as well as conductive ink in bottles like that. It'd probably be a better deal anyway.

And I think there are copper conductive ink pens, no?

Madmax22,

That is exactly what I wanted to hear!!!!! :)

Thank you so much for posting that.... but you know what the next step is now right?

With the 1333MHz strap you might be able to squeeze even that little bit more!

Keep em coming all,

I don't believe that going to the 1333 strap has to be that complicated. I believe you might be able to get the same result by simply isolating BSEL2 (the one with the red trace as shown in your picture) with a small piece of tape and not running that long trace to Vcc that is located 5 pins above it.
