Tried it in the P4P800 Deluxe (thanx to Hipro5) but has a problem. When it boots it gives the max voltage at all lines and thats something asus doesnt like. When it reads more than (equal to) 3volts at ram it just dont boot or it boots one in ten times.. Have anyone else experience with the P4P800 mod?
Was the mod for the P4P800 the same as the P4C800 ??
Maybe they have overvolt protection on the P4P ?
Yes it was the same but the spot you had to mod is in different place.Quote:

Have you done a step by step to building your PC, it seems to be pretty similar to mine.Quote:

I'll probably leave it at this for a while, I lost 120mhz on the OC by going with 1:1 instead of the 5:4 divider, but my memory bandwith is alot higher and the system "seems" more robust. + I'm able to do this at 1.6v vs 1.7v
Also the New beta bios v1007.006 rocks !!!! really improves memory bandwith and seems just as stable if not more so than v1006
Also any1 find a step by step guide to installing this Vmod? I have a few friends after doing electrical engineering in college, probably best to get these to preform any mods to the board?
I just need to tell them to do what with what basically.
Solder 2 wires, one to the middle leg on the VR, and one to anyone of the other two legs on a 50K VR.Quote:

Then solder one wire to pin6 of the LM358 IC, and the other wire to pin 4. simple and effective.
Be sure to set the VR to it's max 50K ohms with a DVOM to start off with. Besure to turn the VR very slowly when adjusting the VDIMM
If someone could confirm my understanding I'd appreciate it.
On a P4c 800 Deluxe I take a 47K pot. solder a wire on the single leg, another wire on one of the two legs on the other side. Solder one of those two wires to pin 6 as shown in the photo and the other to pin 4 as shown in the photo. It doesn't matter which wire goes where. I do this with the ram out of the machine and the bios settings to 2.55 the lowest setting. When I power on machine I test the voltage at the other location in the photo and get a read on where it is compared to where the bios was set. I should be able to adjust the adjustable pot and monitor the change with my meter. I want to set the reading at the voltage check point to 2.8. That is .3 higher than the bios says and it will remain .3 higher than the bios reads as I change the bios setting. So tht when I have the bios set to 2.85 it is really 3.15. I hope that is right I've been reading this thread for about 3 hours now.:D
That pretty much sums it up:)Quote:

I dont know were the other guys came up with adjusting it with out any memory installed??
I tried and their was 0 voltage in the dimm slot or at the MOSFET.
So I did the first {test} adjustment with an old stick PC 2100 in one of the dimm slots:)
Just did the mod, really quite simple, took about 20 minutes.
At 2.85v in bios, I got 3.15v.
Just be sure to turn the POT slowly when you adjust for even more vdimm :)
250fsb, 1:1, vdimm3.15v
NICE very NICE. Good timnings too :)
Thanks for the confirm. Guess there is nothing left but lllllllllllldoit.
I hope i did mine correctly on the p4c800-e.
47k ohm pot
:toast:
Hehe, another overclockers.com member is here to bum advice of you xtreme experts!! :D
OK people, got my 47k VR from Maplins yesterday, no-one seems to know WTF SMD grabbers are there though! Anyone got a pic of one?
http://www.fit2deliver.co.uk/markodude/47kVR.jpg
http://www.fit2deliver.co.uk/markodude/47kVR-side.jpg
I have a couple of questions -
1 - Is the middle post on this VR the ground? If so I take it I can use either of the others as the second post and one stays blank?
2 - How do I know what the max and min settings are? I am guessing that when the bit inside that turns touches the post the wire is on, that is 0 resistance and when it is touching the other one (that I wont have anything connected to ) it is at maximum resistance?
3 - What do Maplin call SMD grabbers??
Thanks in advance people
OK thanks for the help people, I got the VR soldered up and am about to order a Pomona SMD Grabber rather than soldering....
markodude welcome to the Xtreme !! ;) Glad to see you here !
It appears you earlier post got burried !!! sorry nobody responded to it. I hope your mod goes well, post some results when you are through !

3.25vDIMM
http://www.fit2deliver.co.uk/markodu...26-5-2-2-2.jpg
3.15vDIMM, alllows me to tun my CPU at its usual setting where I used to have to run RAM at 2.5-6-3-3
http://www.fit2deliver.co.uk/markodude/cpu3195-1066.jpg
Pin 6 - I used the same one as the rest of you but still cant work out how it is pin 6
vDIMM can be measured with no RAM in the slot
Board overvolts by .1v on vDIMM during boot process.
Max voltage I used was 3.35v and I could not get DDR533
Cheers peeps
Yeah, I need to get my other stick back from my mate to see if dual channel works....
Has anyone measured to see what fixed resistor will give an offest of +0.3 to +0.4?
DoGMaN, I did and posted it somewhere in this thread ! just have to look
I just came back with 8 pairs of SMD grabbers, 100 meters [!] of single core wires, some 15 turn 1K pots and some 18 turn 10k as well.
Most of the people here are using either 50K or 47K pots.
Please tell me I did not buy the wrong pots - [no big deal, just need to run out again]
If this is ok, anything that the gurus need to point out to this voltmod newbie?
Thanks all.
Since the mod is the same for both p4p800 and p4c800, I assume that same resistor values produce the same voltages to both mobos.
I have a p4p800.
Roughly,(some finetuning may required) with a 15K resistor you get an .2 offset, while with a 10K resistor you get a 0.3 offset.
Now, if ur going for the 0.3, your 10K pot will be ok. If u go for the 0.2(and don't wanna buy a new pot) you can solder 2 10K pots in series and have a 20K pot, which will give you plenty of finetuning options, lol.
Thanks RootX for your prompt reply.Quote:

I have the P4P800 as well! I posted here coz I understand that the mod is similar to P4C. So if I understand correctly, 10K pot is fine for .3 offset, and two 10K soldered [three feet together with the turns aligning? Or facing opposite directions? Or don't matter?] will give me 0.2 offset.
And when i adjust it, I just need to turn ONE of them, is that right?
What about the 1K? So are they useless to me now?
TIA
I guess the 1k are useless, unless you wanna solder them altogether - kiddin'.
Now, in order to solder the 2 pots together, what u have to do is turn the litlle screw all the way till it can't go any further, and measure the resistance between the middle terminal and the other two.
One measurement will show 10K while the other will be 0.
Do the same for the 2nd pot.
What you have to solder is the terminal from the 1st pot that you measured the 10K resistance, with the terminal from the second pot that u've measured the 10K resistance(not the middle ones, but either the right or the left, depending on which gave you the 10K).
Now, as for the mod part, u have to solder the middle terminals from the two pots; one to ground the other to the 6th pin of the LM358.
By adlusting one screw of the two, you'll have a min of 10K, if you need to go below that, then you'll have to adjust the second screw.
But please, before connecting the terminals to the IC or ground, measure with a multimeter that the resistances work as expected.
RootX,
I have been trying to imagine what you are trying to say, and have constructed a diagram - please comment if this is right.
Alternatively, a single 10K pot will suffice as well, yes?
Just to satisfy my curiosity, what will a 1K pot yield? I've got like, 9 of them ...
Thanks so much.
Well, this is what I came up with, a diagram similar to yours.
For me, 9.7K were enough for the .3 offset, a friend tried with a 0 Ohm(grounding the pin actually) and he got the max of 3.24V, but that's what he said - I didn't tried it. So, I don't know if the 1k pots can do you any good actually.
I believe that if the 0.3 is what you go for, then a single 10K pot will be ok, but remember not to install any memory before you have finished with the measurements and adjustments.
HI
oh my first post*gg*
I have questions....
what i need??
1. 50k ohm = 3,15 volt ??
1. 47k ohm = 3.3 volt ??
cable ...
ok
mod 1.
pin 6 + 50k ohm* + ground*ground on the fan connector??*
mod 2
pin 6 +50k ohm + pin4 *is pin4 ground???*
OK I got a dumb question. When I am measuring my unmodded board, I get 2.79v when the bios is set to 2.55v and 2.903v when set to 2.85v. I am measuring where was shown in the earlier posts. Like wtf?
mem in or out of it? I get higher volts when my mem is out of it, modded, or unmodded, so I just leave it in and adjust it...Quote:

I remember MS mentioned he didn't have the problem but I do anyways...Quote:

With mem in I need to up about 0.15V to get the correct offset though the offset is correct when the mem are not slotted.
Thanks RootX for the step-by-step guidance.
Anyway I did this on my P4P800 [sorry if this is a wrong post], and one thing I observed [and advised by RootX] is that anything beyond 0.3 offset [above 3.15V max] the voltage goes a little crazy - like sometimes drops to about 3V or wouldn't budge from the max point.
I just cant understand how I can measure the vdimm. I can see in the picture only one point. The second point where is it ? Sorry if it is a stupid question ! :D
I'm a noob at Vmodding, but it should be from the point you're mentioning to a ground...
Thanks! I did the vdd mod with the help of a friend, and it worked out ok :)
Measure it right at the Mosfet (Orange SMD grabber):Quote:

I'm getting ready to do the vdimm mod here and I wanted to know where to get the stuff for it. 50k pot and grabbers that is.
Thanks
If I am doing this mod like NyCUndaGrounD on the previous page, and I am using a 47k vr like marco...which pin goes to which leg. I am having trouble understanding the pin # and I don't understand which leg goes to the ground...
It shouldn't matter as long as you know which way to turn the knob to increase/decrease resistance. You can determine this using a dmm before you install the pot on the mobo.
:cool:
so if i am dealing with the right and middle leg, I can attatch either one to the leg of the chip, and the other to the ground? So then I don't have to worry about which is pin6 and pin 4 because it doesn't matter?...cool. After working with a soldering iron for about an hour today i realized that I could probably realy easily solder this mod on. I was using solder that was waaaayyyy to think and i was still able to accurately place the solder on to an equal sized leg in the middle of a similar chip without making contact with anything else. I may still do the smd grabber way just to be able to take it off for when i sell it (if i sell it). That way the future buyer doesn't have a voided warranty.
I got my grabbers and VRs in today, right in time for the weekend! I gotta get this mod done to my board so I can pump 3.2v through this hyperx 3500 I got :) Putting my swifty tech block on too! Hopefully I don't have any disasters this weekend!
I went with the 4pca3+ rev2, but I think I might still pick up a p4c800-e and see which i like more. I couldn't pass up being one of the fist americans to get the rev2. I love epox, so even if it isn't quite as good how big could the gap be?
A nice plus was not having to do a vmod. I still have to do about 10 of them to other mobos and gpu's, but 1 less to worry about is nice. It will be cool to shoot 3.3v through my khx 3200 b-5 that got here yesterday, and my 3200 geil gd that can do ddr482 on 2.75v with 2-3-2-x timings.
OK, I got my 50k vr and my grabbers. I want to be extra sure that I am doing this correctly. Tell me if I am wrong, but this is how I understand the mod to work...
Solder one grabber to the middle post on the vr and the other grabber one of the other posts. Now turn off the computer, unplug it and remove the ram. Hook the first grabber to the second post from the top on the left. Hook the second grabber to the top post on the right. It doesn't matter which grabber is hooked up to which side, just as long as they are on the correct posts. Make sure the vr is at the highest resistance. Now turn on the computer without the ram in the mobo. Turn the bios voltage to 2.85v. Now take a reading with a multimeter from the post on the mofset pictured below. Slowly turn the resistance down (voltage will go up) on the vr till the multimeter reads 3.15. Now turn voltage down in bios so when you put the ram back in the computer it isn't running 3.15v. Turn off the computer. Put the ram back in. Start up the computer and enjoy up to 3.15v mem adjustments.
Is all of this correct? This is my first voltage mod of any kind. Some help would be VERY much appreciated!
You got it ;)
Be very careful when measuring off the mosfet and not short the measurement point to the center pin on the mosfet ! that could be deadly to the mb !
Thanks man, I'm trying it right now!
ok, I got everything hooked up as it should be. But when I lower the resistance on the vr nothing happens to the vdimm voltage. I know that the multimeter is hooked up correctly, because when I go into the bios and set the voltage up or down the multimeter changes corospondingly. But when I lower the resistance on the vr nothing happens on the multimeter. What am I doing wrong? I can post pictures if you need them to help me out.
neyoung those are the right legs on the vr.
The only thing I can figure is that your DMM might be set wrong ??
Also did you start with the VR at the highest resistance ?? if its a 10 or 15 turn it might take a few turns before you see any real increase in Vdimm on you meter.
Also if it makes you feel anybetter, the max you can get out of the Vdimm cirtuit is only 3.15v - 3.2v regardless of how low the resistance you have the Vr set too. so you don't have to worry about hitting your ram with 3.5v or something (i wish it would go that high ! lol)
Major, here is a pic or the resistance on the the vr. It is a 15 turn vr and I turned it so the resistance would go down for quite a while. After I had it hooked up and was turning the resistance down without change, I unhooked everything the resistance said 35k on the multimeter. So I know I was turning the correct way
Ok, I'll bet you are just going to have to turn it down quite a bit before you see any significant change in Vdimm.
If I remember correctly, I pulled my Vr off my dead P4C800 at it was at about 8k for a .3v offset. So why don't you set the Vr to 12k and reinsert it and go from there.
ok, I'll give it another try tomorrow night and let you know what happens. Do you by chance know the resistance on your vr to get the .3 overvolt? If not no biggie. I will get this damn mod working!!! :) Thanks for all the help Major!
Well my memory is not the best in the world !! but I think it was 8.3k ?? for a .3v offset. So if your at 35k you got a long way to go !!! I'd start at 10k and go from there.
ok, that would make sence why it wasn't working! I didn't want to keep going not knowing if everything was right or not. I didn't want to be overvolting the whole time and smoke my board cuz I had something hooked up wrong. But now that I know that everyhting is good I'll just keep lowering the resistance till the vdimm starts going up. I'm sopposed to go slowly when increasing the vdimm and wait for a second or two and let the voltage stabalize before going farther correct? How small of increments should I go before letting it stabalize? .1v?
Sounds about right ;)
Have you any clue about making the Vcore fluctuation fix mod ?
I have located the ADP3180 quiet easyly ( under the chip retention system, on the left side ) and it is not at the same place as onto the P4P800.
I was wondering if anyone has already hooked a 250Kohm to it on the P4C800 models ?
PS: I'm feeling a bit culprite to left my AMDs setups after 2 years but I gained +10K points in aquamark3 just from 237x10.5 Barton => 240x13 P4C : with no Vmod yet and watercooling not yet mounted
So much troublefree these Intels chips :toast:
OK guys silly question here,
Would the mod work if I used a 10K VR that I use for my 9800 mod? Currently i think she is set at ~2250 ohms for my 1.85vgpu setting.
Or should I just get my mate to build me a grabber mod tomorrow 100% properly using a 50K vr? Or can we even use a 20K vr maybe? Just as long as the resistance is correct?
Cheers :)
can't leave well alone huh ? build me one too :DQuote:

The 20k might work... I'll let you know when I get my mod done. But the 10k is VERY questionable, probably not.
All good. I got the 50K vr and did the mod...about to put it on now :)
Its a §§§§§ getting the grabber in there due to the vid card being in the way but it will do for temp sollution :)
Cheers for the thread help guys :thumbsup:
It is easier to just take the video card out rather than working around it
eheheh...sometimes we miss the simplest things :DQuote:

Where did I say that I wasnt taking the card out? ;)
I am not doing the mod anyways. The legs are too small for my grabber I think and tbh I cannot be fooked taking of the prom head and everything else to slide out the mobo tray to just put a mod on that Ill use for 2 hours.
Ill wait for a bit till my mate can solder it permanent for me :thumbsup:
Cheers
:)
Are you putting the grabbers at about a 45 degree angle? I couldn't get them to hook at first when I was going strait down at the legs. Go at an angle and it should work out fine.
.
Might try it again tonight maybe but see how it goes.
Would u recommend putting the prom on its side for 5-10mins?
COs Im finding it hard with case upright and rekon it would be easier on its side.....or should i just stop being lazy and take the mobo tray out, which means taking off prom head....:rolleyes: :D
hehehehe
yeah i know removing evap head is a pain.... i'm dreading it when i have to check the cpu contact hehe
OK mod is on but now I have this problem.....sent this to mate on icq;
2.55, 2.65, 2.75, 2.85 and vdimm doesnt move from 2.82
lol
I think i have to adjust the resistance so I did and now i adjusted it to be 2.85 while 2.55bios and then now it still the same , everything gives 2.85 now
i thnk i put the mod on when the vdimm was at 2.85 in bios.....would that matter? Cos I think u meant to have a 2.55 and then turn off pc and put mod on...but ive cleared cmos since putting mod on too.....basically the mod is OVERRIDING bios it seems atm.....
Any ideas anyone?
Cheers
:)
I'd suggest your measuring the Vdimm in the wrong location ?
hmmm Ill get the link to the pic im using as guide....maybe its the p4p pic?
http://sapp.telepac.pt/raptor/vmem_reading_2.jpg
Its raptors pic from front page of thread....:)
ALso I just turned the pot 10 more turns and it measured as 3.26 :eek:
So the mod is working I think....but the bios isnt affecting it.....maybe the Rev 2.0 *does* have different circuitry?
hmmmm hmmmmmmm
Here is where I am measuring mine ffrom with pic on my own board just taken 2 mins ago
http://users.bigpond.net.au/batmaun/...2-2223_IMG.JPG
Also do u think also maybe it is touching the pin below?
http://users.bigpond.net.au/batmaun/...2-2211_IMG.JPG
If I can just adjust manually, I wont mind, but if there is something wrong then I should prob take off mod.....:)
I have been measuring some more guys and Ive found that the top left one, the one I thought was vdimm, is changing and when I put 2.85 bios I get 2.92 and at 2.55 I get 2.82.
Now there is another fet that is similar and ive circled it below, the its the top right one. I measure this and at 2.55 it reads 3.02 and then as I rasied the vr like the previous paragraph, and now this value is 3.12. Bottom leg :)
http://users.bigpond.net.au/batmaun/...2-2221_IMG.JPG
I think one of these 2 are the vdimm guys, but Im not sure.
:)
Ok guys, have no fear, I have worked it out :)
With the vdimm mod on, 2.55, 2.65 and 2.75 will all give me 2.82....I then change to 2.85 bios and I get 2.92
I changed te vr a little and not 2.85 is 2.95 and the rest are 2.85. Ill do some more experimenting cos as I said, the top tight fets bottom leg goes up as well and is at 3.12 when the other is at 2.95.....so Ill maybe do some ram timings and work it out :)
I THINKG ive got it worked out, but if anyone thinks different then for sure jump in :thumbsup:
Nup its not working but I have it working manually......well Its at 2.85 bios and Ive adjusted the vr to give me 3.10, and currently testing
230fsb 2-5-2-2 PAT On and System Turbo is pretty stable :thumbsup:
If your bios says 2.85 and you have 3.1 going through the vdimm then everything is working correctly! Good job!
Yep I have 2.85 vdimm in bios and then real its 3.25 measured with mm at the original proper spot :)
If I put it at 2.75 or 2.65 or 2.55 it then drops to 3.15.....is this what it should be doing?
Im going to get it soldered on properly tomorrow :thumbsup:
Cheers for your help bud :)
If you have 2.85 in the bios and 3.25 when measured with mm, then you should have the following.
bios 2.75 = 3.15 mm
bios 2.65 = 3.05 mm
bios 2.55 = 2.95 mm
The vr should just increase the amount of voltage for every bios setting.
If you have
2.75 = 3.15
2.65 = 3.15
2.55 = 3.15
then something is probably wrong.
I get the 2nd option, but it must be real when measured cos my ram is doing better now than when I just had the 2.85 default :thumbsup:
Something is wrong, but Ill take it for now :)
hehehehe
just to check 1 last time, what would you guys say is the highest voltage i could run through bh-5 24/7?
I got 3.2xx running through it now, perfectly stalbe at ddr500 2-2-2-5. It could do upto ddr490 or something like that 2-2-2-5 with 3.1xx so that would be fine being that I doubt I would need much more 5:4 with a good 2.4c.
This mem and mobo seem realy good...too bad this proc is a pos. Maxes out at about 3.39@1.65v, and no more voltage affects it, and with the stock cooler more voltage wouldn't be good (just for the first testing phase. The pelt goes on tomorrow). This 4pca3+ rev2 undervolts the vcore like crazy...like .052v, and overvolts the vdim by aobut .04v. They are very stable, just not lined up with where they are suppose to be.
Well I just did the mod and put 8.9k on he Pot and it was 2.6v before and now it is .. 2.6v :confused:
I have managed to make the BIOS readings for general voltages go from a poor 11.8v to 11.7v and 3.28v down to 3.20v ...
Errr , not too successful.
Sigh. And my soldering was pretty good tonight, didn't even get any on the pet cat.
Regards
Mr 2.6v
I have got mine stable at 240fsb 2-6-2-2 with PAT on and System Performance at Turbo using 3.25vdimm. This was with just default NB heatsink and the thing was reaching 70dc!!!! :eek:Quote:

Imve put the water back on and will test now today 1:1 again. I think that you should be right for up to about 3.30vdimm for testing, but dont go over 3.15 for everyda 24/7 imo :tumbsup:
Cheers

I completely fogot about nb cooling...I wonder if that was affecting my 4pca3+. I don't think so though, because that stock cooler is nice and big, and I have a huge fan blowing alot of air across it. I am gonna pull it off, lap it, and lay on some as3.
How much difference do you think a dd z-chip would make? I got a new pump and rad coming, and I could get some pretty good temps in the water going through the z-chip.
Ill be able to tell you this afternoon whether a Silverprop Nexus is better than the default black heatsink :thumbsup:Quote:

ah found the thread.. nice pics Creative :)
You think that would work better than a z-chip, or the new swifty nb cooler? How easy is that thing to mount? On the 4pca3+ I only have 2 of those hold down loops, will I still be able to use it?Quote:

Nice Mod Thanks to Macci,Works Well I Went With .25V for now.
Im not in any hurry to smoke my Ram. 3.1 keeps me within warranty for now and I Was able to tighten from 2.5,4,4,7 to 2.5,3,4,6 But My max OC is Still FSB 264Mhz 1:1 , I had some Cosair PC4000 which I Sold Thinking It Was My Bottleneck Now , taking Vcore to 1.775 No Help,Any Idea Where to Go Next Vcore Modd ? Vcore 1.8+ ,Vcore Mod, More Vdimm ?? Ram timing No Help
It may be your chip, 264x14 is alot better than my 2.8c would do on air, best stable 24/7 speed was 250x14.Quote:

Stuck the Prometia on it and now 3.920mhz {280x14} is tops 24/7 stable
Thanks to all the ppl here that offered their help for this vdimm mod.
Way to easy! I used a 20K resistor with a grabber. Whole procedure lasted for 15-20 min.
Now i can run my corsair pc3500 @ 233mhz 2-2-3-5 perfectly stable. :)
Good work JoeBar, the corsiar with Bh-5 loves Vdimm ! I wish I had a mb that could give mine some serious Vdimm like 3.6v !!! I'd be able to run mine at 280mhz ! lol
Thanks Major! :)
It's true that corsair loves vdimm. The only prob now is that my mem can go far more than my cpu. So i'm stuck @ 233mhz... :(
i luv u guys
i first vmod, easy thing i have ever done. but
i only put 2.95v to my mushlink lvl 2 3500, and it didnt help even 1mhz... think it really needs 3v to see any improvement? currently its stuck at 290fsb 5:4 2-2-2-5
More than 2.95v would help the situation... ;)Quote:

Also try ras to cas delay 3.
more volts. Don't drop ras to cas. I would go as high as 3.3v without thinking twice to keep the timings as tight as possible. At 3.3v you might need an average 80mm casefan blowing on your ram, because they will start to get a little warm.Quote:

This is probably a dumb question but how do you lower the resistence on the pot?
Haven't done the mod yet so I want to make sure I know everything before I do. :)
Nevermind about the VR resistence, figured it out myself hehe. For some reason though I can't get the voltage over 2.9v, no matter what vdimm I set in the bios.
Hrmm.. I successfully volt modded my P4C800.. running 3.15v. The wierd thing is.. I can't get my FSB up any higher with the higher vdimm. Before at 2.85v the highest stable 1:1 FSB I could achieve was 265 and now with 3.15v there doesn't seem to be a difference. Whats the best bios for 1:1?
My volt mod using some SMD grabbers.
May i suppose by lowering the resistance on my VR further will get me higher VDIMM than 3.15 currently set at?
If yes would it be ok for the ram and the volt regulator chip? itself?

LOL, you just stuck one leg of the pot in your fan header :D
How long did it take you to do this mod? 5 seconds? LOL
Nice idea.... :toast:
No need to solder the leg of the fan header anywhere else and make a mess mate...
I can "remove" the mod like this anytime + i can setup the VRs resistanse anytime ;)
U know what happens when u need to RMA a board and u have messed it up...i like nice and tidy mods :D
I have been wondering something...Since the max voltage this mod will allow you is your 3.3v line -.1 or .2, or something like that...what would happened if you didn't use any sort of resistor. Just ground pin6 and set the 3.3v line accordinly so that your max vdim is where you want it. Since you will have to raise your 3.3v line if you want over 3.15v anyway, why not?
Would this work?
Warm when your just surfin but finger burning when your doing something intensive. Don't believe, go ahead and grab those heatspreaders after running 10 minutes of memtest at 3.3 volts :p:Quote:

Yeah i can confirm that...and it doesnt need 3.3V to feel your fingers burning...3.15V is enough...my mushkin need some sort of cooling in them i guess to make them run higher with more stability...
looping 3dmark or prime95 they were not hot until 3.3v, and with a fan they were fine...anyone have an answer to my previous question?
