upgrade from 6600 to e8600 getting bsod's

Specs: Windows 7 Pro, 3.33ghz E8600, 8 gig Ram
I recently updated my EVGA 680i motherboard with an intel e8600 dual core 3.33 ghz cpu, and it has given me issues for the past 2 days. I was running a dual core 2.4ghz without any problems with 8gb of Kingston HyperX8500 -1066mhz ram, and it was 100% stable. I installed the new processor and a huge Zalman 9700 copper heatsink to boot - and the temps are icy at <30c - no problem there.
The motherboard is running the last bios (p33 from 09/2008) and all reviews of the this chip with similar configurations say it is stable and overclock-able steady up to 5ghz, so - now I am scratching my head.
I will clear the CMOS and reset the bios to defaults, then reinstall the RAM ( I had to disassemble the whole rig to get that Zalman cooler in and attached to Mobo) so perhaps that will help.
I have read that XP and other OS's have required full reinstall of OS - HOWEVER I am running Windows 7 Professional and it fully recognizes it and has installed the proper CPU driver updates automatically. I am worried that the NVidia software is part of the problem seeing as to how it dumps to BSOD whenever I try to access their software. - but it is not just their software that causes it, I had it dump me out when I was doing everything else I normally would - and rather quickly at that.

Any Suggestions from people who have had similar issues are more than welcome! Thanks

I'm curious if you had the E6600 overclocked? It would have easily done 3.0GHz.

According to the JEDEC standard, all DDR2 memory is supposed to run at it's default speed at 1.8v. The fact that your RAM requires 2.2v should have tipped you off that something's not right. Why would DDR2-1066, which should run at 533MHz at 1.8v, require 2.2v?

Since you switched to the 1333MHz FSB CPU, did you underclock your RAM to 333MHz speed to match the CPU frequency (1:1 ratio)? Or are you running it out of sync at 533MHz (5:8 ratio)?

"I have read that XP and other OS's have required full reinstall of OS"

If all you did was change the CPU, you do NOT have to reinstall the OS. I don't know where you read that, but I suggest you stop taking any advice from that site.

BTW, 5GHz is unrealistic. Did you get that info from the same site?

I get the impression you might have reset slightly out of order. Clear CMOS - check, then Reset Defaults, then reinstall RAM, then cooler (heat sink)....
Unless that 's a typo. You should Clear CMOS, then fully assemble, then boot to BIOS and reset Defaults (or optimal settings if available) after CPU/Heat Sink/RAM/Hard Drive/Video Card are connected. No overclocking until you establish stability and normal temperature range. Check in BIOS that CPU, Memory, and Video are on normal settings, not Hot or Turbo settings and make sure you do not have any OC software active.
Reread Answer #1 again.
Check that your memory is on the support list for your MB. Try getting updated drivers for MB. for your version of Windows 7.

Thanks for the reply. Yeah that RAM's settings default at 800mhz at 1.8v, but Kingston rates them as stable 1066mhz at 2.2 or 2.3v and sells them as such - which it was with the other processor - and no I wasn't overclocking that processor. I am just running the new one at the stock settings of 3.33ghz and letting the Mobo determine the voltage. I would not try for more than 4 ghz out of it if I did OC it. I am not that ambitious - if I want that kind of speed I can get a new I7 or something. That's not necessary for what I do. Sadly there's a glut of OC sites that post crazy numbers and settings - I would rather not melt my chip ;)

I just recently went from 2g of 667mhz ram to 8g of 1066mhz, 512 mb Geforce 7950 to Geforce 450, and Windows 7 Pro - so I was ecstatic with that difference in performance. Then this went ----ehhh not so good.

I will give a few more things a try and see what happens...as soon as I get back in front of it. thanks

Here's the model # on the Ram, and I did do the homework on it, and it ran flawlessly at 2.2v with 5-5-5-15 2t setting @1066mhz with 1066mhz FSB of the 2.4ghz 6600 proc. - Kingston KHX8500D2K2/1G (4g matched sets)
Ok, phase 2 testing...Default Settings all items -
<again, edited out non-essential monkeying around>
I will advise on what happens as I progress.

Note to self, stop blathering and just run with what the guy above said about getting 1:1 here... Bugger all

To get Ratio 1:1 you need to underclock your RAM back to 667 though you can bring it back up again as you overclock it (if it does not rise with the oc), BUT running it as 800 and 1.8V should not get you the problem you are seeing.

I have read through some of the forums on using your board with the E8600, and since the E8600 is the last of the series, depending on the version you have and the version of your BIOS, you will need to get the newest version of your BIOS to get support for your CPU (one mentions a P33 version to support the E8500 & E8600, but check their website to be sure). They apparently have 3 methods to upgrade of flash your BIOS, One upgrade works in windows, one flashes through floppy (traditional) and one uses CD.
other info:

Just update your BIOS and you should be just fine.

I currently have the latest BIOS already installed (P33), however I am thinking it could be possible that it didn't take 100% when I did it 2 years ago. I used the NVidia software from within Windows to do it at that time. I will try to update it again and go through all the steps suggested for a clean BIOS flashing.
I gave up last night after mucking around for several hours with memory settings and such with no success, and reinstalled the 2.4ghz 6600 chip. Had to cut it short though cuz it was 1:00am by the time I had finished putting hardware back together so I will work on it tonight and tomorrow and update you with my findings. Thanks again for the follow up and the helpful links you all have provided.

I reinstalled the 2.4ghz e6600 and reset everything back to how it was before I tried the e8600 cpu. booted up and everything is working like nothing bad happened. I did Disk Doctor and several other tests and found no problems.
I read on a post on EVGA Forums that said using the NTUNE and other older NVIDIA tools and drivers with Windows 7 can cause havoc, so I uninstalled those. They were crashing hard whenever I tried to load them during the E8600 tests.
The BIOS is good - P33 - which is the last one published - and it was the one that allowed the intro of Wolfdale procs and 1066/1333 FSB functionality.
Posters on several sites suggest that trying to run 4 sticks of 2gig RAM on this chipset can cause havoc - and to try adjusting UP the SPP voltage (and just about everything else) to make up for the draw on power and timings caused by the deficiencies in the memory controller's handling of things.

Now I need to figure out what to do about the timing and voltage issues so I can attempt to reinstall that damn new CPU. I will try running the CPU and RAM at the settings suggested here and elsewhere, as well as make incremental (scientific) adjustments to the voltages in an attempt to reach stable stock speeds. Tomorrow. For today, I am going to enjoy this computer working how it should.

Please feel free to add any educated works hereafter in an attempt to help - it is much appreciated.

Ok, so I think I got this figured out. The 1:1 ratio to hit on this e8600 processor/ EVGA 680i SLI Rev 2 mobo/ 6400/8500 series memory config seems to be this:
Set FSB to 1600mhz (400mhz x4)
Set Memory to 800mhz (stock voltage SPD of 1.80v at cas 5,ras to cas 5,ras precharge 5,tras18,2t trc23)
Bump CPU Voltage to 1.325 (could go lower but don't go higher to be in spec)

This effectively give me 4ghz cpu w/ 1600mhz FSB and 800mhz RAM speed - which from what I am seeing now, and have read about - is the intended speed it should really run at to be stable. I've come across some lengthy posts quoting this config as the "ONE" - for stability and speed without compromise. You can see there are some nutty OC'ers out there who have gone to 4.5ghz and up - but for now I am a happy camper - and for what this little chip costs ( $289 at newegg) I am tenative about going much faster for the moment. ;)

I will run this around the block a bit and see how it goes.

Thanks again for the help guys.

If you have any problem with stability, leave the frequency/FSB/RAM settings and back down on the multiplier a point or two. Once you find stability you prove you are not having problems with board or memory and you can experiment only with the multiplier and CPU voltage settings. Make sure you monitor the temperatures with speedfan or similar and get a feel for idle and normal stress temperatures. If they are reasonable, then stress test the rig for stability. Maintaining the 400/800/1600MHz you now have, giving you optimum FSB and Ratio (1:1) is what you should shoot for, even if you need to keep the multiplier a little lower.
