Can some one post pics for vdrop for this MB. :D
Thanks in advance!
I'll go ahead and second that request, I can take pictures if needed.
Then what are you waiting for?
My board has arrived - vdroop is covered, vcore soon. Will try and get pics up later today.
ISL6334 PWM controller
Vdroop - between pins 14 and 15 I measured it to be around 18.8Kohm so I'd recommend starting with a 100Kohm variable resistor.
Vcore - you could go down the usual variable resistor between FB pin and ground but this controller does have other voltage offset capabilities. I have found that the OFS pin has been tied to ground via a resistor. If this resistor was replaced with a variable resistor and the resistance increased you can increase the output voltage. Decreasing Rref did not seen to affect output voltage.
Stay tuned
John
The Vcore-mod is not really necessary tbh. I run up to 2.04V on the board and it can do higher than that. Vcore might be interesting if you want to fine tune the voltage, because the 0.05V steps in the BIOS are kind of huge.
I see there is an OVP mod out too with also boosts vcore - kills two birds with the one stone ;)
do you have a link? :p:
I45 OVP Mod by Hey - looks to be adjusting the VID voltages manually. Pay attention to what he says, don't short the wires ;)
http://img181.imageshack.us/img181/6...45finalog1.jpg
I45 Vdroop mod by me - work in progress as I still haven't found the time to do the mod. My measurements were off as the traces are so small actual resistance is more like 2.2Kohm so a 20Kohm variable resistor will suffice.

will this vdroop mod work for the tp45hp board to? at idle my vcore is at 1.456 and loaded it goes down to 1.42x vcore. i would like to have stable vcore so i dont have to have it so high to be stable. ill keep lookin to see if its the same.
Has someone measured with DMM, how big are drop and vdroop?
ANy idea how to do the mod , i really need it , sorry for bumping old thread
makaka, which? Here is Vdroop posted allready and should work. Just measure the resistance to be sure.
Thanks for reply , were this chip is located i was looking and looking and have not found it :DQuote:

What would be Your first choice for Vcore mod? "Regular" FB->VR->GND or this OFS moding?
For Vdroop I also measured 2,19kohm resistance. I'll do the mod as soon as I have measured the real voltages and drops with DMM...
Other pics if someone interested: http://ceemic.pri.ee/hardware/tpower/
i am very interested in the vdroop can some explain who to do it clearly . between witch pins should i place the resistor and how much ohms ??
I measured real Vcore with DMM and here are results:
http://ceemic.pri.ee/hardware/tpower.jpg
As You can see, Vdroop rises badly in higher Vcore. So when You want to squeeze max MHz in sub-zero cooling, Vdroop mod is a must ;)
And as someone mentioned here before, Vcore mod is also recommended for fine tuning.
Vdroop done and working :)

I tuned it so, that it overvolts 0,001V at load. Also it rised "def" Vcore about ~0,003V. I used 20k VR, but according to readings it was tuned to ~4570ohm, so 10k VR should do also :up:
Tho, it may vary on what CPU you are using and Vcore...
glad to hear it worked out Ceemic ;)
http://www.overclex.net/data/images/...VDROOP_MOD.PNG
This mod works fine too :)
Johnny Bravo, tnx ;)
Pt1t, do You have other mods for TPower also? :p:
would this be the same as the tp45hp tforce board? i really need it mine droops from 1.456 idle to 1.40 to 1.41 under load.
Thanks men this what i need exactly , a pencil mod , how much 400 ohm will help in the vdroop ?:DQuote:

ok Pencil mod 3 posts up works. I could not get it to measure 500 ohms but measure 1.687kohms but I penciled it to 1.5kohms and now no more vdroop it stays right on exact set voltage in bios or overvolts a tad ;)
philbrown23, use coil legs otherside mobo (the pins nearest to socket) ;)
I even drilled holes to case :D :
http://ceemic.pri.ee/hardware/coil_leg01.jpg
http://ceemic.pri.ee/hardware/coil_leg02.jpg
Now I have soldered a wire there (look pics in my previuos post in this thread).
yeah looks like ima have to solder one to
anyone can give me VMHC mod??? i need more than +0.7v :D
Johnny would prolly be the best candidate for that as he is the vmod guru round here. I'm trying to find a vdram mod myself. but it's a definate pita
anyone have the actual resistors for the vcore mod or pics of the vcore mod? seriously .5 jumps are a little rediculouse and on a wolfdale that could be thediff between the safe zone and non safe zone for water and air cooling.
Still no vcore mod???
philbrown23, measure resistance FB->GND and multiply it with 20x, so You now which VR to use ;) I'll do the mod in next few days and report back.
sweet!
looks like I need to get my soldering iron out... LN2 on the tpower soon for me...
I am also very interested in the vMCH mod if there is one.
I am reading 2.17k on that resistor for the pencil mod. why is it different? what should I pencil it down to?Quote:

philbrown23, if so, I'd recommend 50k VR. It has "smoother" end. You need to adjust 100k too far and can't adjust Vcore so well...
I haven't had time yet (yesterday I moded a HD4850); probably I'll do it on Friday and report ASAP.
Can someone confirm that Vcore mod?
http://www012.upp.so-net.ne.jp/ohij2/vcore-mod.jpg
I can't atm look, which PWM pin it's connected with.
philbrown23, maybe You have time to do the quick measurement? I'd like to know the resistance from that point to GND. Thanks!
Macro from that place: http://ceemic.pri.ee/hardware/tpower/tpower20.JPG
measurement from that point to ground= 44.6kohms I think it'd connected to the same pwn but iunno
EDIT: I CAN confirm that pencil mod, it actually works better than the other one in the beggining of this thread, before I still had .1 vdroop now I have a mere .003 vdroop ;)
~45kohm? Have You disconnected all stuff, including CPU, from board?
This resistance should be around 5-10kohm, so 50-100k VR would work.
well I mis typed the resistance was 4.46kohm not 44.6 rofl, I was in a hurry, cuz I had to head to work. but yeah just under 5kohm
Then 50k should work. Is that point directly connected to FB pin or which?

Thanks.
DiscoTech, I'm talking about hard-mod. I don't ever use pencil mods ;)
Not trying it thread-jack but anyone have measure points for this board? Vcore, VTT and Vmch most importantly
Thanks
if you read up a few posts you'll see the measure point ;)Quote:

50k VR is overkill, I even wouldn't recommend 100k VR. Use 200k or 250k VR for Vcore mod.
I used the same wire which I had already soldered for Vdroop mod:
http://ceemic.pri.ee/hardware/tpower/tpower_mod03.jpg
I just applied 200k VR to the extra PCB :)
I have switches also, so for 24/7 I don't use Vcore mod ;)
Little helping picture for moding. FB and VDIFF traces shown:
http://ceemic.pri.ee/hardware/tpower/tpower20_mod.JPG
The resistor that controls Vdroop can be "pencil moded" also, AFAIK :D
Good luck everyone!
philbrown23, have You removed the resistor and is Your board alive? 50k VR rised Vcore too rapidly I quess and therefore it didn't post...
yeah my board still works so basically 200k? hmm what is lowest vcor with full 200k resistance?
I had +0,05V in BIOS - 1,276V real. After Vcore mod 1,287V. Haven't tried it with lower Vcore, because it's pointless :D
I only did it for better adjustment for sub-zero cooling and higher voltages. 24/7 it's OFF.
Probably it will affect linearly every selected Vcore value in BIOS by ~0,01V. So the lowest Vcore rises +0,01V.
where can I buy some 250k-ohm pots? I've been tring to find one but cannot.
With this I can't help You. Here in Estonia, I can buy 200k and 250k also. Prices are ~1$ per one :)
man that sux!
i usually buy from here but there temp out of 250's.
http://www.hosfelt.com/en-us/dept_141.html
well now somehow all the sudden my Vdroop went from .05/7v to .1v?? WTF this is nuts, now with stuff on auto for stock settings, I have to up the vcore +100 or it will not post winblows!. man this sux.
well I got my vdroop mod all set to be soldered on. as far as the vcore mod I guess ima have to wait till I can fin at least 200k. the place nate dogg linked to has some 200k's but I'll have to wait till I can order at least 55.00 worth of resistors.
In these pics, those smd grabbers look like theyre easier to use than soldering... but is it safe? effective?Quote:

If you use 50k VR, the max resistance is 23,5k and that's might be deadly :)
I would even recommend 500k VR - max you should get is 40,8k.
Thank's Ceemic (again) :)

DonNiger, ~250k VR + switch is better than 500k VR. First, You can switch the Vcore mod off for 24/7, so it won't be dangerous. Second, 500k VR will have too rapid end to do some decent fine-tuning in higher Vcore (You'll have to adjust it too much to get some higher Vcore and these VR's aren't linear in the end). 200k VR rised Vcore only 0,011V, so it's not dangerous :)
helle forim germany. somebody knows about pencil mod ? somebody knows about abiosupdate?
and, can somebody help me adjusting my system?
E8600 4ghz @ 1,091 reaper 9600 dont know how well they go
tpower board
dark power pro 650
maybe somebody can told me some settings. gtl maybe and all this things:D
thx
ok,no answer :( i tried the pencil mod with the two points of the asian site, but nothing change by using pencilmod cpu vcore ist the same like before:D
MiniMe1978, what Vmod You meant? Vcore? Why the hell You need pencil mod for Vcore?
http://www012.upp.so-net.ne.jp/ohij2/vcore-mod.jpg
this is the one i mean. why? why not :D? because, the settings are too much different between +0.025 and - 0.05 :( its a range 0.075. why there is no +- 0 ? or an standart fix vcore? normally my e8600 runs 4ghz@1,091, but with the possible settings in bios i cant run this optimum. because, with -0.05 im without last at 1,088 an with + 0.025 im a little too high. or was it -0.025 and + 0.05? i dont know, but the jump is to high. i need a little between this settings :( an maybe with pencil it will run stable with 1,088 because at prime it go down to 1,07x:D
I tried Vdimm mod and it works grate. But before you do it, please delete your OC profiles or at least, change DDR voltage back to default. I'll tell you later on why.
Mod:
Mem read points. That is the first try, I used too big VR
http://static1.nagi.ee/i/p/334/81/08370473093265_o.jpg
http://static1.nagi.ee/i/p/334/81/08370475640927_o.jpg
That's my final - ofcorse, you can use switch and a 1K3 resistor aswell for 2,0 startup or 600R for 2,35 startup.
http://static1.nagi.ee/i/p/334/81/08370477b0442d_o.jpg
And now the reason of deletion.
I set 2,3v for startup (minimum for my OCZ sticks), vent into BIOS and loaded my max profile. But there was set to add + 0,750v for DDR. So, F10 and multimeter showed me 3 - 3,2v for some time. That floating is not because of the vmod - voltage floats even with def settings from 1,8 to 2,0. Sounds like it has been set to find the minimum voltage for memory.
And now those sticks are in a freezer :scope:
so set the ddrvoltage to auto or +.50v?? i tried the ddr mod but was tring the wron controller as the other pic looks more like the long controller rofl.
After doing the mod, I did clear Cmos - so first startup was auto. Later, I set it +0,05.
sweet thanks
And I made a little mistake. With my setup (1K VR + 270R), the maximum bootup is 2,35v (turning the VR to 0). SO, it is pretty safe mod.
I'll probably do the mod today and will use only 1k VR:DQuote:

I used 1K VR. At def Vdmm voltage changed 1,898V -> 1,993V (BIOS show'd 1,872V/1,968V)
+0,050V@BIOS voltage changed 1,952V -> ~2,05V (BIOS show'd 1,920V/2,016V)
Then I tuned VR so Vdmm is ~2,35V when +0,050V@BIOS :)
I also did OVP mod

PS! Can some moderator change the title of this topic? For example "Biostar TPower I45 Vmods"...
Probably work better if you PM'd a mod to change it, I doubt they read every single post
