eX400 pin mod

[PCTC2]

yeah, i know you can pin-mod an e4400 to be in the 1066 strap so you basically have an e6600, but would it be possible to set it to the 1333 strap as well?

XS 1333 Pin Mod

It didn't work for him b/c he has a 975X which doesn't support the 1333 FSB. would it work on an eVGA 680i, which does support 1333 FSB? set it to the 1066 strap by grounding BSEL1 to VSS (so BSEL1 is set to 0 (Low)) and then isolate BSEL2 (to set it to 1 (High)) and get it to 1333 FSB? that'd be pretty dope. 3.3GHz with minimal strain on the NB with a larger overclocking potential --- AT Forums e4300 Pin Mod to 1066 for higher OC potential.

and would it work (setting to 1333) on an eVGA 680i with a e6400?

just wondering if i should take the plunge with either.

I don't know, maybe, there's no really obvious reason why not, but you should change your thread title from eX400 to e4X00 because the second number is the variable one, not the first.

 

[PCTC2]

well, it's eX400 cuz I have an e4400 and a e6400.

Does the mod work on the e6400? I mean it's already 1066 so what would it do, make it 1333? Sorry, but I don't know that much about this mod, I thought it only made the FSB 800 processors run at 1066 by default.

Oh, I see what you were doing...e4400 because that's the known pin mod, and e6400 because you're asking about it, so you're trying to reference both with 1 title...is that right?

Wait...no, it should be e4X00 because if it's a variation of what you're referring to then you're referring to the known mod, which is on the e4300 and e4400...

I guess it's really not that important... >_>

 

[PCTC2]

I guess i should've explained myself clearer. I want to set both to a default 1333, even my e6400.

 

[PCTC2]

another question for anyone. can you use superglue to insulate BSEL2? and where can you get conductive ink pens?

You don't use conductive ink. Use a defogger kit and take the copper out. Carquest/Checker/Pepboys will all have them.

Just use a toothpick to take the copper out of the container. Also if you screw it up, it comes off with alcohol.

How would you go about setting an E4300 (or 4400) to 1333?

 

[PCTC2]

FSB is set by BSEL0, 1, and 2 (Pins). Their grounding (Low setting) or voltaged (High setting) in a set manner determines FSB setting read by the motherboard.
IF BSEL0 and 2 are set to low and 1 set to High, then 800 is the default FSB.
If BSEL0,1, and 2 are all set to low (all grounded), then the motherboard reads 1066 as the default.
If BSEL0 and 1 are grounded (low) and 2 is voltaged (High), then the motherboard, if it is capable, will read it as a 1333MHz Default FSB Strap.

To do so on an E4X00, BSEL0 is already at low. BSEL1 needs to be grounded to VSS. BSEL2 needs to be voltaged, or read as so, so it can either be connected to VCC or insulated. Because the link from BSEL1 to VSS is in the way, BSEL2 needs to be insulated.
333*10=3.33GHz

With a E6400, it is much easier, as BSEL2 can just be connected to VCC rather than grounded.
333*8=2.66GHz

This is nice because it allows the motherboard to run on a 1333 strap automatically rather than hitting it either never or above 400 (1600) FSB. A little less strain on the NB.

EDIT: This has been proven to work (E4X00 to 1066 and E6X00 to 1333) but the combination for E4X00 to 1333 has not been proven. I think I'm going to try it next week or so (still waiting on a few more things.)

EDIT2: Why do people use conductive inks as well then? and why are the defogger kits better?

Sounds awesome, PCTC2. If you get the E4400 to 1333, would you please post some pics and all that? Because...oh man...that would rule.

So, let me get this straight...my understanding is that the FSB strap (which I first heard of today) determines how high the motherboard can go based off of the CPU's default FSB, so by tricking the motherboard into thinking the processor is at a higher FSB by default, your level 0 on the overclock, from the strap, will be 266 (or hopefully 333) instead of 200. This would, theoretically, let you overclock further because the motherboard can go further since it's starting point is higher (assuming the processor can handle it in the first place). Is that right?

 

[PCTC2]

The chipset (north bridge) operates on the clock with tight timings. The strain on the northbridge often limits overclocks because the chipset just can't take the high clocks and tight timings. A higher strap allows higher clocks with looser timings putting less strain on the north bridge, theoretically allowing a high clock. Voltages will still need to be high for those monster OCs, and voltages will be higher at "stock/auto" speeds but technically the mod might help with stability because of chipset limits. So you are basically correct except voltages still need to be high, but the Northbridge and FSB are basically at square one, zero strain.

And i'll post the CPU-Z, SuperPi, and all that stuff after I get the motherboard (eVGA 650i Ultra) and a few other parts. I'm too lazy to rip apart my current rig to put in the E4400.

If you do the pin mod to set your E4400 to 1333, I doubt it would even boot up. But good luck trying.

Conductive ink pens can be found at Radio Shack.
