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,

Bryan d

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.

http://www.xtremesystems.org/forums/...d.php?t=132900

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).

http://www.overclock.net/intel-cpus/...en-4-0ghz.html

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.

http://ec2.images-amazon.com/images/...CLZZZZZZZ_.jpg

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.

You got Defogger Grid Kit or Adhesive ? I just bought the adhesive from Ace Hardware PI Mall, and i can't found it at Puri Mall. According to Ace's Costumer Service (via email), the adhesive only available at PI Mall, Blok M and Pasaraya, and the Defogger Grid Kit will be available at June :shrug:. That's too long

Got Kit one, but its long time ago for pre C2D pin modding.
Heck, dunno where did I put that small vial ? If I can find it, will pm u if I can find it, only need few swipes though !

Vortan, thanks for the pics. I hope this will settle all the silver naysayers

whats wrong?

i used this pen and waited for it to dry 15min.
http://web.telia.com/~u15011310/Cpen.jpg

result:
http://web.telia.com/~u15011310/test10.jpg

im using the DS4 mobo.
i can boot up at 9x350 over that and the computer wont boot up.
if i use Easy Tune5 i can easy get 9*390 and its stable but i cant boot at 9*390 so i have to clock the last bit from Easy Tune,no big deal.
400Mhz and the computer hangs so i guess thats the Wall with E4300.

as for Easy Tune5 i have found a bug.
1.58V is max over that and the computer shuts down.
i can go for 1.6V or more in the bios but as soon Easy Tune starts the computer shuts down.
what the hell is this limit for?
anyone know i you can disable the Vcore Limit in Easy tune5?

im using watercooling so the temp isnt a problem

could it be that you are using ds4 rev1? been waiting for feedbacks about it but it doesn't support a higher strap other than 1066. i believe for it to work, our mobo should support the 1333 strap. thats what i read on other pages here...
goodluck, though i can be wrong

My p5b deluxe doesn't seem to like this mod, it get's stuck in a reboot cycle with BIOS 1004(haven't tried any other BIOS). I was reading on other forums and I'm not the only one with this problem on this mobo, so is there any other way of doing it, cause if not, I'm getting a e6300/e6400,

i think thats the problem :)
i orderd rev 3.3 but i got rev1.

im sending it back and hope i get the right mobo this time.

Finally i'm done the mod by using Circuit Writer Pen :D...forget defogger kit :D

http://img.photobucket.com/albums/v6...0/e4300mod.jpg

http://img.photobucket.com/albums/v6...conductive.jpg

Now i can reach FSB 394 Mhz with n680i (before only FSB 303 MHz)

I think we need to start making a list of what mobos support this mod. So far i know the p5b does not and I know one of the Gigabytes doesn't also,

Why doesn't the p5b? P5B supports up to e0 conroes (1333) with latest bios. And 266 has been supported since the start. If it's not taking the 200->266 mod, then you're not doing it right. If it's not taking the 200-333 mod, then it could be bios/motherboard.

It's possible some boards boot using known default settings coded in the bios after reading the chips microcode ID, thereby ignoring those pin signals completely.

My Asrock Conroe865PE board does not seem to work with this mod, after downgrading the BIOS to v1.40 (which does not officially support E4300), the board boots up at 266MHz FSB, even in the bios the auto setting shows 266MHz, so the board must be ignoring the FSB pin signals, mod was removed to verify this.

i have this board too, and you can boot any processor to 266 just by putting the overclock jumper ;)

I've tried the repair kit, conductive pen & even using copper wires MULTIPLE times and nothing. I know I read somewhere else someone with the same mobo had the same problem but I guess I'll wait for someone else to try it and see what BIOS they are using if it was successful,

Yes you can overclock to 266FSB but not with the "auto" (where it defaults to 200FSB) setting with any bios later than v1.40, v1.5 and 1.6 you need to manually set the FSB to 266, you have a E6600 of course it defaults to 266 :P

If it doesn't work you could try an older bios >pre< E4300 microcode support.

hello gyus

but this mod is can be done also with a normal pencil mod?

thx

Some good & bad news for P5B deluxe owners. Good news is using any BIOS from 0711 and down automatically boots the E4300 @ 2.4GHz without doing any mods :D but you do get a CPU ucode loading error every time you boot. Now for the bad news, overclocking is not improved, the FSB "wall" is the same, at least on mine. Also, after modding the CPU, it now boots but no change in the FSB "wall" either but I'm still testing and I'll report back if anything changes,

what was your fsb wall before mod?

With BIOS 0711 & down, mod or no mod, it boots at 2.4GHz(266FSB) automatically. Modded, with BIOS 0804 and above, it doesn't boot, just gets stuck in a reboot cycle. As for the other question, look below,

Prime stable is 395 but sometimes it will boot 400 but never 401+,

I had a 300FSB "wall" on my E4300, then I updated my AW9D to a bios that supports 1333 strap natively. Selected that and it's at 333*9 (3GHz) at stock volts atm.

I hope by Natively that means No Mods to the cpu? If so when I get a cheap stick of ram that does 1.8v I can set the bios(Hopefully, as I put a Noctua NC-U6 NB heatsink on Mine and the Noctua is solidly mounted as It doesn't move), As My current ram won't boot below 2.1v(2GB OCZ PC2-8000 Gold GX xtc[2x1024MB]) and being I have the old 1.3 Bios and not the New 1.4 Official Bios(Unless I'm wrong the Bios version won't make any difference here in this case, Can't flash It with ram that doesn't get enough voltage). I'd cleared the cmos as I had a QX6700 cpu on this motherboard at one time with a multiplier of 12, If the multiplier had been set at 9 It could have booted. :(

That was the original plan in the beginning of the e4300 pad mod, but it was not successful at all. For some reason or another BSEL1 was getting a low signal, or the circuitry did not want any of it.

Either way, the BSEL1-->VSS is the best shot.

Plz excuse my ignorance, but I gather that the 266/1066 mod definitely works for the e4300, but does the 333/1333 mod work? Any word on either mod with the e4400? Thanks.

is there a list anywhere of mobos this works on? I only have P5B-DLX and it doesn't work.

I would love to find a good mAtx board to use for budget builds.

mod works great, thanks

I did bsel mod on my E4300 Q643... with silver and they work, defult boot at 266, but I don't get any improvement on fsb. Before and after bsel mod wall is 405 fsb. Board is biostar 965pt with 0404RH bios.

So for a e4300 is it better to run a 1066 strap or a 1333?
Also does this only work with p965 boards and not 650i?

hey Dekara did you try the 0119 or the 914 bios, thats what i used for my 4300 with the bsel mod when i had my biostar, it broke the wall i had and i got some crazy oc's out of it for a 4300

no pen for me on my e4300

Ok, I'll try both of them bios and post result here.

Well...does it work on a P5B Deluxe or not?
Because i want to buy a E4300 today...and i want to do the mod directly after i bought it...

NO the mod does not usually work on the P5B-D, i know that in my case running the 0711 bios on the p5b-d worked the same as doing the mod without doing the mod

and Dekara i think the 921 bios worked as well

i tried a e4300 on my p5wdg2 ws pro and it seems my vcore is locked to auto with this cpu ? i tried the mod with conductive pen don't work yet , i tried it twice . i am going to go grab a window kit today and try that . i can get the cpu to 3ghz with vcore on auto but thats about it . never heard of not being able to set my vcore . is this cpu vcore locked or something ? will i have to pin mod for vcore also ?

here's the 1333 fsb mod , plus i'll be trying 1.41v mod also .

Hi guys
I have an e4300 (Q635A165) and for every multi I have a different FSB WALL (because i think that it's this the problem!)

with 6x max bootable is ~417 of FSB
with 7x max bootable is ~364 of FSB (http://www.hwupgrade.it/forum/images...n_confused.gif)
with 8x max bootable is ~415 of FSB
with 9x max bootable is ~414 of FSB

With vcore default I can get until ~350(x9) of FSB

BTW my daily now is 400 x 8 = 3,2GHz @ 1,36v with ram in syncronous at 4-4-4-11 @ 2v on Asus Commando

400 x 8 = 3,2GHz with ram in sync at 4-4-4-11

This is a screen with my e4300 and my previous Intel D975XBX

http://img139.imageshack.us/img139/1239/4074334yj7.png

Now my question is: with this mod can I break my strange FSB WALL? :confused:

My E4300 FSB Wall with mult 8 is 385, with this mod, i can get FSB 400 x 8 1:1 ?

I think nobody can tell you straight away - you have to test it yourself and let us know ;)

I tried last 6 different bios for biostar 965pt 103, 119, 119RH, 119RH2, 0404, 0404RH and result is same, fsbwall on ~405 fsb :mad: . Neither bios won't boot 400 fsb with 6x, 7x or 8x multi but 9x work ok. Several bios just don't like lower multi than 9x on 350-400 fsb. I'll try another ram and 914 bios but it's small chance to change something.

EDIT: I try 914, 914RH, and 103RH bios and still nothing :( .

Yeah but point is that bsel mod don't change fsbwall on my 4300. Btw this is XS forum every fsb, mhz, seconds, point... is important ;) .

Does this mod work with 650i or does this wall only appear with p965 chipset?

Confirmed this mod works for the e4300 and ecs p4m800pro v2.0
cpu boots at 266 x 9 default and can be oced to 300fsb.

2.7 ghz for a $100 mobo+cpu combo at frys. This was during the frys anniversary sale. I must say, such a sweet hometheater pc.

I can say that the bsel mod doesnt work with p5w dh deluxe bios 2004.
I've redrawn it at least 10 times, and no sign of it working.
1066 mod boots as 800, and 1333 doesn't boot at all.
Drawing done with a silver conductive pen and checked with a multimeter.

Did anyone try it with P5N-E SLI ?

Will this work on other 800 MHz FSB CPUs like a Celeron 440?

:cool:
Hello ...


Does this mod (e4300 Fsb 1066) work with Msi 975x Platinum v.2 :cool: ?

Anybody did it?



Other question?

i know this mod isn't guarantee for oc, because i can't see what temp?
Anybody have air cooler, but idon't know than it's very hot or no


Note:
Still I have not used 975x because i haven't power supply, hard drive, etc.. so my new computer's incomplete.

If i do mod my e4300 fsb wall, with HSF zalman 9700 and artic silver 5 ?
And i do my setting 9x400 = 3600, Voltio (don't know, maybe normal o more)
So what is my temp?:confused:

Please anybody can advice me about temp for e4300 mod wall fsb???/:up:


Thank you :D:up:

i dought it, if your running the stock multi you are prolly at the cpu's limit. as i had my E4300 doing 380fsb.

350 is the wall on the lowest multi, for me. I was more interested in it because someone here said it helped them overclock to the same speed with less voltage, and overclock higher.

works fine om my asus?

i'm hitting 350~360 wall... with no mods

my prossie run tom DFI Infinity, using NB trap in bios
using with volt 300mv in bios.
batch code L640a497

Did the mod on a E2140 and an Asus Pundit P2-P5945G.

Worked as expected even with speedstep on (6x266 on idle, 8x266 on load).
