I would like to keep pushing the Q720M.  I honestly have no idea what is wrong with it though.  Now I can't hardly exceed 150Mhz Bclock.  I was having this problem before too, but it seemed like a certain combination of memory fixed the problem.  Now the problem is back again full force. 
 
ARggh!  I want to get some boints!
 
I did see the core voltage spike for a split second at 1.8-1.9v at one point while drawing the pencil on the PWM controller.  I wonder if I nuked it.    I am getting memory related BSoDS while overclocking past ~150MHz BClock.  I wonder if I screwed up the IMC.  Anyone have a Q720M (A.K.A 720QM) lying around which they don't need anymore after upgrading?
 
On another note, I was wondering if anyone has some advice regarding getting XP working on my laptop.  I have tried slipstreaming SP3, SATA, and Chipset drivers into the XP install disk, but still I get a BSoD while starting the install (after it is done loading drivers and first starting the setup process) relating to my hard drive.  I don't know if it is the SATA CD-ROM drive which is tripping the BSoD or the SATA Hard drive.  Maybe it is a problem with AHCI versus IDE mode (which I have no control over with this laptop).  Any thoughts?  Success stories?

Ty_ger07, that's probably a question for John, resident laptop guru.  But I seem to remember an issue with my D900F that you couldn't run XP.  Check the notebook review forums too.

yeah, not going to go to much into that voltage thing..since i didnt use it with my 720 and it ranks near the top... but you got me beat there at trying...only thing i might have tried was boosting 133 to boot 166. then start over clocking from there.

if we had the msi laptop. you can mod the motherboard to boot 166.

well hot damn! nice going there!!
 
and congrats to you Q for all you have put down so far!
how you like the ln2?

diziam!!
you talk about some serious close numbers there...
 
so the tanks are a success then? very cool!

Hey thought I'd share my 260 gtx from hell. I do have a full waterblock for the 260 but didn't feel like prepping the block plus I didn't have enough eraser. Just run this last-night with chilled water and got 3D06 @ 820 core before the mod on water my max was 760 core. Card temps during load are about 10c.
This set up will allow me to swap cards out pretty fast, loving the old DD GPU block .

I like it threedhero!  We got outta caring what it looks like long ago....held together with stings and suction cups, who cares, it can kick ***!

well i did some more tweaking and had some interesting results.
i read in shamaino's old i7 overclocking thread that you can "improve" your vantage scores by playing with the IOH voltages
 
sadly this did not work for me, results:
 
specs: 3way SLI 800core/900mem GTX 470
4.3ghz 980x
 
stock IOH (1.1v)
P40029 
GPU 41057   CPU 37230
 
IOH 1.2v
P39919
GPU 40905   CPU 37227
 
IOH 1.3 QPI PLL 1.15 (stock 1.1)
P39798
GPU 40754   CPU 37183
 
may need some more tweaking, also my clock may not be high enough to have to worry about those voltages
 
anyway i just thought i would share

Ln2 is something else.  There is definitely no relaxing when playing with the cold stuff.  I'm getting 50L tomorrow and we'll have a go at it again

Just got my 2 golds back from sniper.............for now, lol.
Single & SLI 9800gtx
 

I just so happen to have those cards too ;)  Once this mill is done being built... I will be back in the game.  I miss this stuff.  Sitting on the sideline SUX!

 
Absolutely!  The more the merrier

You probably don't have to worry about that too much.  IOH vcore rule of thumb is 1.1 for one gpu, and add 0.05 for each additional graphics card.  I run mine on auto.  In fact I run all voltages on auto except vcore, dimmv, and cpu vtt.  Honestly I found no difference across the chip samples I have for i7920/980.  Then again it just may be my beautiful 759 classy that's been holding up for a year and 8 months now, lol!

Yea, its disgusting outside!

@john
 
thats what i would have thought for the IOH. but with 1.2 scores went down so i dont know what to think
 
also have you got any insight as to why my CPU score went down buy 1500 points when i added the second and third card?

what what...q56 was solid at 5.4 ghz! very nice!!
damn near grabbed a 6 ghz as well!!

Thanks guys, but I'm bummed I can't bench my 480's.

Who me, hellshealer?  Strange to me too. I think maybe pcie socket a little damp,lol!  I switched to pcie socket #2, which I never use, and now I got it to pass vantage oc'd @1900/2250.
 
Not home yet though.  Now waiting for the chiller to pull down temps and we'll see how it goes.
