Default weird boot after recent oc

I recently OCed my cpu a bit and raised the vcore a bit.

The Problem:
1. It boots all the way up to the Windows loading screen, but it bluescreens when Windows is supposed to show the log-on screen.
2. The computer restarts
3. The computer continues to boot all the way to the desktop as if nothing happened. The OCed cpu seems stable here. no bluescreens

This happens consistently every time I boot.
So how do I fix the blue screen?

dont turn off your computer... problem solved

what processor do you have? what operating system do you have? what powersupply do you have? what mother board do you have? what ram do you have? how high of an overclock did you do? what cooler do you have? did you adjust the RAM timings at all.

post screen shots of CPUZ of the Memory and CPU tabs plus load and idle temps...

Obligatory specs

Attachment 4483Attachment 4484Attachment 4485

mobo: EVGA P55 SLI E657 (FTW)
PSU: 645W

Also, I have a stock heatsink. My temps go up to 80 in less than a minute during stress tests. I'll need a new heatsink. It stays around 50-60C for gaming though
My cpu isn't overheating. I can see the temp on the motherboard as it loads windows. (50C max)

hmm, well one thing i see funky is the timing on your ram...


7-7-7-20-135 that cant be right... it should be something like 7-7-7-21-36 if you can link us to your exact ram we can see what the timings should be and that might have something to do with it.

Also... 80į is alarmingly high, i cringe when my AMD gets over 50į. but to be honest, i dont 100% know what the danger zone is for intel chips...

Your vcore is too high for your current OC, you should be able to easily bump it down to under 1.3v for a 3.2Ghz OC

What's the error number you're getting when the BSOD happens?

Go to Device Manager and rollback your Network Adapter to it's previous Driver.

Memory
OCZ DDR3 PC3-8500 Gold Low Voltage Dual Channel OCZ Technology

I think it is a memory problem. I set the trfc down to 88 and the bsod disappeared. I just set the value a bit high to make sure that it'll boot.

So how do I find the right tRFC timing? It's really unstable right now.

Download and run CPU-Z, go to the Tad labeled SPD, it will tell you the recommended latencies for your memory.

CPU-Z
Useful
but it doesn't give any information on tRFC.

The internet doesn't seem to have reliable info in the tRFC timings either...
