Q6600 is acting funny

I had my Q6600 up to 3.3 ghz stable. I was using a cheap Star Tek ball bearing fan until my TR 120 Ex arived. I tried taking a short cut and not take out the MB to put in the TR back plate. I tried using the back plate that was already under my board. Needless to say, when I run prime95x4 my temps were 86C for a very short time. So I took my board apart and put in the back plate that came with the cooler. My temps went to 33C idle, to 46C with prime 95x4 running for 4 hours. But heres my problem. When I rebooted after getting the cooler set with the right back plate, it would not boot. I had to reset my bios, and fix my clock set ups. And for the life of me, I can get it over 2.84 ghz. Any farther and it will not post. My c1e is diabled, speed step is disabled. Spread spectrum is disabled. I even raised the Vcore to 1.42, and it would not post. I set my memory to 5-5-5-15 and it also did not help. Could I have dislodged something when I was messing around changing the back plate, not letting me get a higher FSB? My temps are low, 33 is my highest temp at idle, and 46C with prime95x4 running for hours. I have a Q6600 GO revision. I am using an MSI 975X v2 Power Up board. I have a 500w power supply, and a 7900GS gpu, in an Antec Nine Hundred case. I am using Vista HP.

my first guess is because you slamed your chipset voltage settings to default.

I would play with the chipset voltage. Try raising it slowly by 1 to see if you can get a better overclock on it. Go up gently and not too high, unless you can get a fan on it.

Sorry, I did not explain it that way. The listing earlier is where I stopped. The only other change I did not list, I pulled 2x512 sticks of miss matched memory out. I left the 2gigs of matched Kingston sticks in.

One other thing I found. I was looking at some CPUZ snapshots I had taken earlier, with the mismatched ram my timings were listed as 4 5 6 18. Now I have set them manually at 4 4 4 12. Could this odd automatic timing, let me get the previous higher overclock? When I try to set those timings manually, my board will only let me go to 15 instead of 18.

im thinking somethign went wrong in your cmos settings for board and ram.

I would suggest you set everything to default, and then reoverclock.

Adjust your voltage on your cpu, and fsb termination up one until you get your old oc setting back.

For the RAM, use the lowest divider and leave it at the stock latencies. This way you can rule ram out of the issue in overclocking.

I will give the ram a go tomorrow. I may have found part of my problem, Vdroop. I set the Vcore to 1.32, and when running 4 prime95 i was watching cpuz and it was dropping my voltage down to 1.27 and 1.26 at times. Could this much voltage drop make my overclock fail? I did get my speed up to 2.99 today. Thats a positive sign at least.

I was going through my bios again, and was wondering. Do most MB's give you an option for a 5:4 memory ratio. I wonder if I am hitting a wall due to my 533mhz memory getting too fast in a 1:1 ratio? I only get dividers from 1:1 up to 1:2 in my bios.

thats a terrible vdroop.

You need to work your way with the vdroop in mind. Look for a pencil vdroop mod
