Wow... thats what I'm aiming for, 310+FSB with 3:2 divider and FULL pat on 2-2-2-5 BH5s, gimmie your mobo!!!! :p

lol yeah the ic7-max3 did pretty damn well except for the 280fsb wall with the 5:4 dividerQuote:

actually im hoping to get my is7-e up to 308 with the 5:4 divider... might take 3.5v on the memory, but ehh :D
then maybe ill be able to break 23k on 3dmark01
ok learn i got an image of the back of the is7. its of the area directly behind the south bridge and winbond chip... let me know if it isnt the exact area you need

Ok, heres the pics i promised for the vdd mod if anyone else wants to check it out
excuse the really crappy quality picture, tis what happens when a scanner is used instead of a digital camera :D
heres the location of the R115.
http://helsyeah.shackspace.com/vnorthmod.jpg
As described by Learn, remove R115 and solder two legs of a 20k pot into its place.
I set the 20k pot to 4.35k which was the resistance i read from R115. To raise the vdd voltage increase the resistance on the pot.
as with the IC7 the vdd is measured from the mosfet above the agp slot towards the socket.

Sweeeeet, thanks man!!!!! :)
Still waiting for my Antec TP550 to come and do volt mods on that first... argh.... can't wait... fjla;sjklsfdakl;fsda :(
The only problem is, no1 knows if this actually improves stability, yet.... argh
thx for all the pics my friend.Quote:

http://myweb.cableone.net/jeremybtmn...20of%20is7.jpg
it's the exact area.
i'll "photoshop" this
Learn, excellent, i look forward to your "chopping" :D
Ok, i tested to see how high i could go with the 3:2 divider and the vdd set to 1.65... I was able to reach 308fsb again as i had with my ic7-max3. It was stable through memtest86+ but i didnt load it into windows yet. Once Learn gets a diagram of what is needed for the agp mod then ill perform it and see how much further i can go...Quote:

this is the small trace.

sweet, thanks Learn, i'll be performing the mod tonight
I did follow the trace back to the front of the mobo and it went to one of the capacitors on the front of the mobo right below the south bridge... from there it seemed to go to an internal trace in one of the other layers... i would be curious where it resurfaced and the possibility for finding a better location to do the agp mod.... i wonder if theres a circuit diagram of the IS7 floating around anywhere...
hi
yes, a circuit diagram should be very helpful.
i've forgot,
increase resistance, increase voltage.
another thing, the bios monitoring seem won't see the voltage change.
Hey do you guys know where to measure Vdimm voltage? Mine is flucuating too much, I would like to solder a thick wire from the 3.3v rail directly to the MOSFET.
Plz help
Thanks
Also, where do I measure VTT voltage? I think I've got the right MOSFET for Vdimm.... but I'm gettin 3.34v when Winbond HWMonitor says it is 3.23v.... :(
i have no fluctuating problem with my is7e 1.2,
over 3.6v of vddr, i've a problem.below that, no
the bios monitoring seem won't report properly the real voltage.
you can measure the vddr from the two big mosfets below the dimms.(as usual it's the right leg)
take care, it's dangerous (do not short circuit the vddr and the 3.3v rail...)
i've soldered a wires from the vddr,vtt,vdd and vagp mosfets, it's a safe way to mesure the real voltage
edit:
for the vtt it's the smal mosfet (Q67) below the atx connector
So did the Vagp mod help?
I seem to be stuck.... I can pass memtest86 loops @ 295FSB 5:4 ratio, but prime95 causes the system to freeze/reboot after a while... Sometimes even when the CPU was 55C.
I have a fan blowing over the ram, and i even epoxied some heatsinks on the agp and vdimm mosfet, as well as the southbridge, with a fan blowing all of em.
Also, is there a capacitor mod for the IS7? Like the one here:

Thanks
chipset maxed? or your cpu?Quote:

it help a little.
jump from 285 5:4 to 290 5:4 (pat fully enabled, with super pi),
over 290 with the pat fully enabled, it crash quickly for me.
and jump from 255/256 1:1 (pat fully enabled) to 266 1:1 (memory limited )
it's possible, i thinkQuote:

but it help?
How did you enable full PAT? NB Strap 667? I can't even boot beyond like 260FSB 5:4 with full PAT :(Quote:

Are your corsair sticks 256mb or 512, mine are 512
Also, how did you test for stability? Just superPi? I run 2 instances of Prime95 torture tests for at least an hour.
yes, NB strap 667.Quote:

it's 2x 256mb sticks.
it's a bench report, not stability test.Quote:

i'm using prime95, seti@home, game...

IS7-E revision 1.2
I just did the Vagp mod, and it doesn't work. I tried varying the resistance from 10k upto 100k, but the Vagp voltage doesn't change!! :(
I know I did the mod right, because when I unplug the VR, it doesn't boot up.
Oh ya, my board is revision 1.0. Learn, where did you get the Vagp mod?
hi,
sound strange, it work for me.
you have a good ground? and VR?
where have you check the voltage? from the mosfet? bios?
myself, it's the apadated hipro5 ic7 mod, it must working.
