Any know V Mod about this board ? ussually with V Drop ? :) :)
Ya, i would really enjoy a few mods here aswell, weres Johnny or Hipro5:p:
--cheers--
Vdroop & vpll mods are sorted ;) Will post pics soon
What other mods do you guys want ? :)
Sweet Johnny:D ...i knew you could not resist this fine mobo...lol..Quote:

--cheers--
how about vmod for the cpu VTT max on 1,6v
love to try above it :D and see how it goes
Sorry for the delay guys my laptops died so I'm gonna have to host of imageshack for the time being. Both mods are tested to be working :) Pics up in 6-8 hours after I get home from work!
Vdroop

1Kohm variable resistor preset to 500ohms seems to do the trick!
VPLL

Not easy to solder!!! I suggest you put the VR beside the Inductor like so

thanks for the mod bro ill try the vdrop as soon as i could :D
anyway what is vpll?imch?
i think its ICHIO on abit since its default value is 1.5v, same as VPLL default on Asus mobo.
what are you refering to Andre?Quote:

Anybody tested high voltages (2V) ? Any OVP problems, vcore needed?
I don't have the board yet, but will need that soon when I do :D
Cpu vocre max 1,9v with b02 beta bios , I need more vcore , Cpu vtt mod:) Jonnny and Hipro where are you :D
yup like i said before i would love to have more than 1,6v :D
but what is vpll anyway?if vpll is ICHIO why need so much?couse i try to raise mine it didnt make any effect?
1.9v oke with bios but ı need over 2V :D
it's really bad support with mods for this boards
it will be Asus for me next time
@Brandybuck bi abit ix 38 anakartı çözemedin gitti:rolleyes:
brandybuck was this a BIOS limitation or did you set the voltage higher and the board not boot?Quote:

so could you give us some cpu vtt mod :D
Will sort out a cpu VTT mod - beta bios 06 and onwards offers up to 2.11volts!
But ı know only beta bios 02 unlock QX9650 up to 9X multi. I try 02,03,05 but I didn't try new 06 , I will try beta bios 06:up:Quote:

hehe as long as it work (which i believe so,like always) :D i got no problem with that...
btw i still dont understand if we need more vpll?which andre said it was ichIO ?
No I don't believe the two are related as ICHIO voltage is connected with the SB not the cpu. the VPll voltage is directly associated with the cpu and its voltage is generated from a different circuitQuote:

Only beta bios02 working up to 9x multi
Ok so the IX38 hasn't got VPLL setting in bios, right?Quote:

I think I'll pass on the mods... for now. Vdroop is 0,03 with my quad - I can very well live with that :)
Anyways, great work there Johnny! :up:
Brandybuck can you try this:Quote:

no there is no BIOS control for vPLL and it's been shown to help with FSB limits (along with CPU VTT)Quote:

Just flashed your "final" bios 12 btw, works great :)
I got my Q6600 priming@480 FSB so far... however the magical 500 seems to be out of reach. Can bench@495 but not even get a CPU-Z@ 500. Oh well, I guess it's the CPU - but maybe the VPLL mod helps. Hmmm... :D
I tried official bios 12 but still not uo to 9X multi:( , but ıf I enable all cpu features (speed step) , change multi up to 9X . Cpuz shows normaly 6x but under load change 12x:)
This is very perplexing I'll have to check this with abit as it's a major issue if it's broken again :(Quote:

Jhonny , is it vcore mod? or only CPU VTT higher up to 1.5V
CPU VTT mod is a few posts up ;)Quote:

thanks for the vtt mod :clap: :up: will try as soon got time :D btw does the reading on the bios real for the vtt?or we have to make another read point on the board?
It's reasonably accurate
ive just try to find other point that easier for me :) and found this point
http://img242.imageshack.us/img242/1281/imag0107ax8.jpg
mark with black arrow marker.
please tell me that the point are good enough :D then i can solder from there to ground
Johnny , I'm waiting your vcore mod for up to 101k:D
This score only 1,88v with Abit:) , I know over 2v vcore up tu 5600mhz benchable:p:
http://www.hardwarena.com/images/sto...rler/rekor.jpg
anyone knows Vcore and CPU VTT read/measure point ?
p.s. I found CPU VTT read and on my motherboard 50k VR is not a good Idea. I was wondering why mod doesn't work and now I have got my anwser. It's more like 500 ohms VR than 50k
Any vdimm mods?
What bios would you recommend to use on this board?
I saw a few modded on Clunk.org forums, but dont know which one should I use.
Thanks.
And Johnny Bravo, nice work, keep up ;)
Sure you've got that right? 500ohms is waayyy too low for the VTT mod I've given :confused:Quote:

I will check what resistance exaclty I need for +0.2V, I did the mod with 50k VR. I tuned trimmer couple of times, no difference in BIOS or Guru readings and this was in the middle of LN2 benching. So next day I set to figure out what is wrong, so I found read point and do the measurement with DMM and I figured out that BIOS is quite right and I had to turn trimmer all the way to the end and then voltage jumped from 1.4 to like 1.6 in an instant.
What are you setting the voltage inin the BIOS. For me 35Kohm ups the votage 0.2volts so it you are aiming for say 0.8 volts you can set ti the CPU VTT to 1.6volts in the bios and up the voltage using the variable resistor.
I wil show you the CPU VTT read point I use once I get the image hosted
http://www.itsjohnnybravo.com/Overcl...20(Medium).jpg
Red point marks CPU VTT measure point that I use
you have found the most unavailable point :D
I use this one, about bios selection it doesn't mater much which one, it's about the same on all
http://img145.imageshack.us/img145/4...uvtt20mpp4.jpg
p.s. need vcore mod :D
problem with taking reading from your point is that they are not accurate, that is inside the switching circuit, so not a DC signal but AC - needs to be measured past the large inductor to the left of ur measure point :)
Did a quick test this morning and the difference between my read point and your readings will be 0.3volts lower than mine, so you'll be suppling that 0.3volts more to the cpu than you think! I strongly urge you to reconsider your CPU VTT readpoint.
The CPU vcore mod will be up sometime tomorrow as I need to solder it on and test it, then take photos :)
what is the default vpll voltage?
my q66 show 1,65v increasing to 1,7v didnt effect to mac cpu fsb but total clock.want to use more but not sure couse never play with it before any one can help :welcome:
usualy cant post n spi1m at 450x9 now can even though its not stable on 3d
increasing the vtt cant pump my max fsb also :( i think my chip is not good enough still max at 470.already reach 1,75v vtt :ROTF:
thanks for all the mod johnny :up: time to look for better cooling :D
maybe we have different boards then, in my case Bios/uGuru is showing lower value than DMM on this point (also without the mod) and if it would be 0.3V higher, than that means that motherboard is overvolting CPU VTT a lot over BIOS setting (at 1.5V selected bios shows 1.43, DMM shows 1.50)Quote:

VCore Mod (Version 1)
OK I have figured out a way to control the vcore but it's not the most straight forward so while you all try this I will see if there is a more direct way.
OK first thing is to solder a 500ohm variable resistor in parallel with this resistor:
Http://www.itsjohnnybravo.com/Overcl...1%20121ohm.JPG
Now to increase the voltage you lower the resistance BUT this will NOT happen when tjhe CPU Core Voltage Offset is set to 0.0V.
It seems that this overrides the circuit that this mod work on so in order to to make use of this mod you want to maximise your offset voltage. So lets say you set 1.5volts vcore VID and then maximise the OFFSET VOLTAGE before adjusting the variable resistor.
hurray, you'r the man :YIPPIE:
1.9v is selectable in bios so that is too much for most of common mortals, for other, max offset voltage is common sense
p.s. now you can start vmoding X48 board, we'll need all the mods we can get as soon as it's available :D
Of course - looking forward to feedback on how far you guys can push the vcore and how well it copes. keep those Digital VRMs cool!!!
Thx Johnny , I will try this vmod:up:
Hey johny,nice work there as always :)
Can you post a more clear pic of the points for the vpll mod?
Thanx
edit.
Ok...one of two pics wouldn't come up :p
i did some testing about CPU VTT, bios setting 1.30V (btw 1.5V is max),Quote:
Originally Posted by Johnny Bravo

when 50k trimmer is set to 9.7 Kohms it's +0.1V, when on 9.2 it's +0.3
though you record your read point as going up rather than down as I did I'm not surprised as it depends on how your DMM "sees" the fast switching voltage off the MOSFET leg. However you can see that my measure point is more inline with what you would expect to see, plus as it's closer to the socket area it's a bit more accurate to what the cpu will actually get (avoiding any droop that could occur)
Your trimmer measurements do come as a bit more of a surprise, as I checked mine and got +0.1volt from 25Kohm but hey, if it works then it works! :D
true :DQuote:

wait that doesn't make any sense, what is the maximum offset voltage you can select in the bios?Quote:

If you set 1.6v vcore , ı can give max offset voltage 0.3v
no you misunderstand. THere are two ways to change the voltage in the uGuru BIOS for thw IX38 QuadGT.
Vcore goes up to 1.6 votls. hen underneath that there is an "offset" votlage which can go from 0.0 to 0.5/0.6volts.
Is this how your board is?
Johnny , yes I know normal settings 1.6v vcore max , 0.6v offset voltage max:) , but İf you set vcore 1.6V , Offset voltage can set max 0.3v (no 0.6v) . I set Vcore 1.6v and offset 0.3v and max 1.9v in bios or windows(uguru).Quote:

If this still doesnt wrok then there is a safely in place :(
Hımm oke:up: I will try tonight thx.Quote:

This vcore mod working very well but Abit mobo have Over voltage protection up to 1.95 - 1,96v:(
:( OVP is gonna be hard to find without datasheet, but I'll see what I can do, don't think the abit engineers are gonna like me asking how to disable all their safety features :D
Especially when my boards died on me@1,4V max...
any news on that OVP ?
OK I've got some feedback about the OVP
Basically its not a hardware limitation - its a firmware limit imposed by uGuru. It can be defeated but it requires the uGuru firmware to be flashed and the BIOS to be changed.
However - these flashing software and tools are confidential so they are not willing to allow it to be given out publicly :( So while the higher voltages WILL be supported in up coming boards its not officially supported on the IX38 QuadGT :(
I'm pushing to see if there's a way to fool the uGuru voltage sensor so that it sees a lower cpu voltage than there actually is.....
apart from that it doesn't look good :(
interesting :(
hehe why dont we just take out the uGuru chip :nuts:
Well it's confused me no end - the BIOS has the ability to set 2.1volts - the hardware is specced to run at this (and higher), yet for some reason they chose to limit it???
WTF is vPLL?
