So what would i have to do to make my processor a 400 fsb
I tried to paint the L12 of a 1700+ as a 200Mhz the time bios1.1 was out, and the comp won't even boot (it is supposed to 1st boot at 100*11) and the chip could also boot 2200Mhz on default V
I don't know if latest bioses have different policies , i should try this then next time i 'll have time to flash my bios
I was actually going to mod my multiplier to a 10 and fsb to 200 so i can run at 2ghz 400 fsb always in any board
Chile it's already grounded. That's my point. AH30 needs to be set high.Originally posted by chile
it's not telling you to connect 'em, it shows you where they are...notice the Vss/Gnd pins next to them....you're supposed to put the wire in AH30 and the Gnd.
Thnx

Has anyone successfully modded there cpu to a 400fsb
Tried this some time before...Originally posted by Shroomalistic

And no diff to 166MHz at my 1700+ though
And now I got my 2500+ and cannot get 220MHz dual stable. Thought there was no need to mod 166MHz cpu on nf2 400 ultra
One prob follows the other Should i collaborate to intel???
sorry, my bad...i was thinking of something else i saw but it didn't fit here....btw xfrigid, when i tried the 1700+, it did boot 11X100 but when i went to save, then exit still no go at 166....maybe it's just the a7n8x-x....but i don't see why....Originally posted by G H Z

Not a guru , but no, I don't think that can be done without cutting the bridge. At least I've never heard of a method.Originally posted by G H Z
Can anyone post a socket diagram that shows exactly where to jumper wire a 166 Barton into a 133 default fsb chip. I think setting AH30 to high will achieve this, but if it's set low now(grounded), then can a socket jumper even do this?
I don't want to blow a the L12 bridge if I can avoid it.

Look at our FSB_Sense circuit diagrams someone posted above. Then note that if you connect Vcore directly to the socket pin (SP) on the "LO" circuit, you short circuit the 10K pullup resistor and change the LO to a HI. This can be done with a fine wire u-loop/jumper between sockets AH30 and nearby Vcc = Vcore socket AK30...verify in socket/pins diagram in datasheet 25175.pdf.Originally posted by MrLavender

Link to Circuits article to understand how reducing the pullup resistance from 10K ohms to 0 ohms (with the fine wire jumper) changes the "resistance ratio" of the signal circuit's "Voltage Divider" and so changes the signal circuit's voltage level.
And it's safe because the 1K ohm pulldown resistor "limits the current from Vcore to ground". Just be sure that the top of the fine wire jumper does not contact the circular bases of any other pins...maybe just cut a small groove between the 2 sockets to lower the wire jumper a bit just to be sure.

Edit:- See Workarounds article for marked up pic of socket A to locate AH30 and AK30. FSB_Sense article may also be useful.

Ah, now we do have a guru!
Wish I'd known that b4 cutting the bridge on my 2600+ (and voiding warranty).
One question - in the circuits article it says "Note that manual resets of default LOs to HIs using circuits D and H without resistors pose some risk of short circuits, so consider Multiplier bridge mods when mobo/bios is unavailable, or when manual mods with resistors are not practical.". Also, in the Multiplier Workaround article it mentions using a 100 ohm resistor between vcore and the socket pin. It is definitely OK to connected them directly?
Anybody who tries this please confirm that it works for future reference.

Key words = "without resistors pose <b>some risk</b> of short circuits". So it is OK to connect <b>without</b> the 100 ohm resistor connected directly at Vcore takeoff...<b>as long as you are sure</b> there will be <b>no accidental short circuit to Ground</b> between the Vcore connection and the pin.Originally posted by MrLavender

For example, let's say user decides to use fine wire u-loop/jumper between Vcore socket and the signal circuit pin. Then user should be sure that none of the u-loop can project above the surface of socket to be folded over and possibly contact/connect to another pin.
So installation technique would be to install u-loop with case on its side so gravity holds u-loop in place, and <b>never</b> back up when pushing in the cpu as that might drag the u-loop up to be possibly folded over if pushed in again. If you must backup, backup all the way to be sure the wire u-loop is all the way in. Just a case of think what might happen, use your head, and be careful.
If you want to use the 100 ohm current limiting resistor connected to Vcore then solder the resistor to the Vcore socket on the back side or some other Vcore point, then run to signal circuit socket back directly, or thru a switch/jumper for easy toggling back to a LO.
John C.
Edit:- People are connecting wire u-loops between Vcore and signal circuit sockets, just consider the ocinside.de site which has the interactive socket/pin mod guide for Multipliers. It calls for no current limiting resistors...though we wonder if it should also have a warning re accidental short circuits to Ground as we do on our site. [Gets scary when you see the complete circuit diagram and get a warning to <b>understand</b> the consequences...unlike the <b>just do it</b> sites where ignorance is bliss] ;-)

does anyone know, if its important to usw a conductive "gold" pen, instead of of silver ? (because of the specific resitance)
well im finally running higher FSB's now 198 is rock solid! ive done alot of things this past week to improve my volts on rails and chipset volts plus the l12 mod so im not positive if it helped but i know it didnt hurt

hmm i doesn't get a success with a needle, yet... will try it today again...
hey guys. seeing that the newer 1700+ chips have that "coating" on top, the bridges aren't exposed. am i forced to do the paint or wire trick to the pins to get my svc 1700+ to run at over 215 fsb?
my 2400+ will run @ 218 fsb without a problem but my 1700+ 1.5v cpu will not cut that speed currently

...just tried again, using transparent tape for isolating the pins and a needle.. and it worked! . im testing right now :O
i've got a 0322 XP 1800 - also with the "design". So you have to do the wire/paint mod.hey guys. seeing that the newer 1700+ chips have that "coating" on top, the bridges aren't exposed. am i forced to do the paint or wire trick to the pins to get my svc 1700+ to run at over 215 fsb?

Do not see anything...
im using a XP1800+ 0322 WMPW - crappy thing... won't even run stable @ 2.4ghz...
the vdd was 1.85v (dunno, i didn't test anything else...) and my vdimm was 3.22v (is needed for such fsb's :> )
so..this is my end config now...:
how i said.. the cpu is crap...
finally the mod gave me ~14MHz with a very cool vdd...
