1.8->2.4 pinmod/voltmod help please

Hello all!

I am currently in the process of trying to get this pin/volt mod to work. I'm working with a p-m 745 to run at 2.4ghz. I have been sifting through this forum a lot and have decided it's time to ask for suggestions before I give up and try another 745. Bear with me folks, I have never done anything like this before. Here is where I'm at so far:

This is with a Latitude D810 purchased August 2005 btw.
Stock stuff:
Intel 740
X600 - I currently upgraded to Quadro fx go1400
WUXGA
2gb ram

1. Installed the 745 with only pin-mod and booted up fine. Ran prime95 and failed immediately. This got me excited as I read I may only need a slight increase in voltage to make it stable if I could get to this point.

2. I rebooted to test if it still loaded up fine and after logging into windows the system froze up.

3. So I started very low with voltmodding by grounding pins and the most stable I got it at was with grounding vid0, vid1, and vid2. This let me run prime95 for 55 mins before failure. Using i9fangui the processor temps peaked at 61c. The fans were running on high however and I have AS5 applied. Any lower voltage resulted in failing prime95 in about 5 mins.

Does this combination add .812v to the stock 1.340v (I believe it is 1.340v stock checking with cpu-z)? Surely it doesn't as it would certinly fry the processor?

So, from what I understand reading other posts this puts me at 1.452 volts? I don't understand this looking at the chart that many people refer to here: http://img149.imageshack.us/my.php?i...idchart4lj.jpg
It looks like to get 1.452 volts you would ground everything except vid4? But I know through reading other threads you cant ground vid3.

I would like to have it run rock-solid with prime95 for at least a 12 hour period for reassurance. I don't game any, but I will be doing many 3d renderings which I don't want anomalies in or failing half way through. I use stuff like AutoCAD and 3ds Max.

I have not really played with RMclock or NHC or CHC but have the first two downloaded. With RMclock, to set the cpu voltage under Advanced CPU do I just need to hit apply or hit apply and set to take affect after restart? I have not played with NHC at all yet.

If you look at the link below, in posts #5-7 I think, this looks like it might be my next step to get it to work:

But I don't understand what setting the stock voltage to 1.324v accomplishes.

I am also thinking about switching to a higher quality jumper wire before doing anything else to see if it makes any difference as I am currently using some crap (looks like aluminum) out of a broken cordless phone. I hear this may make a difference?

GPU runs just fine by the way.

Sorry for the looong description but I want to give a clear image of where I'm at. Thanks in advance for any help out there!

If I already tried 1.452v with crap wire do I perhaps have a chance with 1.420v with better quality wire? If the wire doesn't make a difference then I don't see it working at 1.420v.

Ah! That explains my confusion regarding the chart.

I will try some copper wire anyway and see if it makes a diff. Maybe reseating the jumper pins will do something, just to make sure everything is connecting properly. Won't be able to find out until after my midterm tomrrow though.

Anyone else out there have any ideas in the mean-time? Think it has a chance?

OK, I'm testing 1.436V right now with 100% copper wire. It wasnt stable for long at 1.420V with the copper wire so we'll see what happens. Maybe with some luck the vid1 jumper I had before wasnt connecting well enough.

Dangit, no good. Failed prime after about 20 minutes. Back up to 1.452V but I'm expecting failure in about an hour. Anyone want a slightly used Intel P-M 745? It was new when I bought it just a few weeks ago.

Well, this one isn't going to be stable at 2.4ghz at 1.452v or below. Failed prime95 after 2 hours and 45 minutes. I'm not going to take the volts any higher even though it only hit 61C at 1.452v. Thanks for everyones help/suggestions. Back to ebay it goes, unless someone here wants it? Let me know.

Yep, I agree. Thanks again.
