Users running the P7N Diamond and QX9650 please weigh in. I need help...

Question

OK, I'll start from the beginning.  I had an EVGA 780i mobo, which ran a Q6600 at 3ghz quite easily.  Well, I decided that I had money to burn so I ordered a QX9650.  It would not work on the EVGA, the cpu voltage and cpu fsb voltage would not adjust no matter what I tried.  So, I popped the cpu into my kids rig, which has a DFI X38 mb and the cpu worked perfectly, voltages adjusted, multiplier adjusted, etc.  During the RMA process to EVGA, I got an MSI P7N Diamond to run SLI with.  Stuck the cpu in it and away I went into Vista 64, all happy.  I had to bump the memory voltage up to 1.95 volts, but that was it.  I then decided to raise the multi from 9 to 10.  I set it, warm booted and tested it in Vista.  100% stable.  2 days later, I attempted to turn my computer on.  No post.  I had to power off/on very quickly to get it to post, at which point I got an error message that the cpu vid had failed or there was a mismatch with the cpu to fsb ratio, hit F1 to enter setup or F2 to load defaults.  I e-mailed MSI and received beta P05 and it was just downhill from there.  I couldn't cold boot at all, stock settings, OC settings, voltages adjusted, it didn't matter.  So back to the shipping bios.  I got a new beta this morning, dated 2/18, and it was the exact same. 
Issues with both beta's:
1.  Cannot cold boot.
2.  Logitech G15 acts erratically prior to entering Vista.
Things I have tried:
1.  Raising Vcore.
2.  Raising NB/SB voltages.
2.  Raising FSB Terminator voltage.
Nothing helps.  MSI simply told me not to OC and run at stock and that there was no problem.  Is there anyone else out there that has this cpu and mb?  If so, can you post your experience with it and let me know if there is something I am doing wrong or could try?

Answer 1

Below is the actual transcript that I had with MSI on this issue.  As far as they are concerned, I don't need to change the multiplier on my QX9650.  (Start reading from the bottom up for the actual order of the conversation)

MSI Tech. 02/19/2008 Then, there is no problem with the mb. 
End User 02/19/2008 There doesn't seem to be any issues with usb while on using the shipping bios, I only see it when I flash to the beta bios'. 
MSI Tech. 02/19/2008 If the stock bios also has the usb issue then try: Have all USB device connected to the rear USB ports that are build onto the mb and retest with all USB header on the mb be removed from any front USB connections or adapter connections and retest. If all steps have been tried and problem still persists then please kindly refer to our website for manufacturer warranty RMA info/request: http://www.msicomputer.com/support/CustomerS.asp 
End User 02/19/2008 No change. I cannot even cold-boot at stock settings with this. Also, it still kills my Logitech G15 keyboard randomly. i have to unplug it and plug it back in to get it to power up, and that is only after I boot into Vista. Back on the shipping bios for now at stock settings. Please, if you would, keep me informed of changes or progress. Thanks. 
End User 02/19/2008 Thanks! I will poat back if it helps or not. 
MSI Tech. 02/19/2008 Beta bios v111 attached to this form.   
End User 02/19/2008 Is there any other beta bios' that you have that could help? The P05 didn't work out so well, maybe you have a newer one that I could try? It seems odd that it is only on a cold boot that I have issues and not on warm boots. I am willing to try anything you got at this point! 
MSI Tech. 02/19/2008 Sorry, but MSI did not see any issue with using QX9650 processor. 
End User 02/19/2008 So are you saying that as far as MSI is concerned, there is no issue with the QX9650 and the P7N Diamond motherboard? I am not asking you for advice on hot to OC it, I am asking you if you know of the issue and are looking into it to try and correct it. If you do not think there is an issue and are not going to investigate it, then I will be very disappointed. 
MSI Tech. 02/19/2008 If there is no problem with standard bios and no OC then you can refer to other website/forum for OC suggestions or settings. MSI does not provide these setting/suggestions since it can cause damage to the components. 
End User 02/19/2008 Also, I am unable to use the Dual Core center, as I am running Vista 64. It does not load properly when using this OS. 
End User 02/19/2008 As of now, it boots and runs fine with the shipping bios and no OC. But, why would I have paid such a high premium to get a QX9650, that has an unlocked multiplier, if I cannot use it? Is this strictly an issue with the newer 45nm Intel processors or is it something else? If not being able to use my cpu's unlocked multiplier is "ok", then I may return the board for a refund. 
MSI Tech. 02/18/2008 What is the problem when system uses the standard bios and not OC? 
End User 02/18/2008 Is there a fix on the way or is it just a problem with my hardware? I have it back on the shipping bios and it is at least cold-booting now, as well as my G15 is working. I upped the NB voltage a hair above auto, maybe this has somethinng to do with it? 
MSI Tech. 02/18/2008 Use the standard bios and use software to OC: http://global.msi.com.tw/index.php?func=downloaddetail&type=utility&maincat_no=1&prod_no=1372 
End User 02/18/2008 I was way too quick to say everything is OK. I now have cold boot issues aplenty. 9 times out of 10 it will not post on a cold boot, but will warm boot. I have to power off then on real quickly to get it to post at stock speeds. Also, my Logitech G15 started to act erratic with the P05 beta. I am back on the shipping bios until I hear from you. 
End User 02/18/2008 Thanks you for the beta. I flashed to it, cleared the cmos and set everything back up and now I have a new problem. Even though I have disabled the EIST function in the bios, it still seems to be on. i am using cpu-z version 1.44.1 to monitor the multiplier and it randomly shifts between whatever I set it to and 6. It is even doing it when the system is loaded, ie playing games. Please, help! 
MSI Tech. 02/18/2008 Beta bios attached to this form.   
End User 02/18/2008 Everything is stable 100%. But, on my QX9650, I set the multiplier to 10X to run at 10x333=3.33ghz. It was fine until this morning. I turned the computer on and it would not post. I powered down and repowered it up and it siad the cpu vid had failed or errored, hit F1 to enter setup or F2 to load defaults. I entered setup and the multiplier was set back to 9x. I left it there and am ok now. Is there a beta bios that helps out operations with the newest Intel 45nm processors, such as the QX9650?
I have absolutely no issues in Vista itself, it is 100% stable.  It is only on a cold boot that I have serious issues.  And yes, I got 3 in a row, went to work for a few hours, then came home and bam!  No cold boot.  Also, I don't know how comfortable I am raising the vcore that much, as 1.21-1.25 is the normal operating range.  1.3625 is aweful high.  Now, with the 65nm quads, that is more in the range of what would be needed, but no way should it be necessary to pushh this QX9650 to a meeger 3.33ghz.  As far as temps go, I have the processor watercooled, so no worries there.  I am away from home now until Saturday morning, so I can't test anything until the weekend. 
Thanks alot for the responses!
