NB Frequency has to be around 2600-2800mhz to help stablize the overclock more_ Its strange but I found out that with a higher NB Frequency I was able to acquire a much better stable overclock than with 2000mhz NB Frequency, *& the plus side is that raising the NB Frequency increases performance tremendously_

Most people can do NB Frequency of 2600-2800 with 1.25-1.35volts

I/E I can do 2800 with just 1.256volts CPU/NB Voltage
QFT. HT link must stay around 2000mhz to stay stable.

Another QFT.....if the CPU is stable at higher clocks,it will be binned as a faster stock CPU at source.

All chips are NOT created equal.All C3's will not hit 4.0GHz easily.That being said,you just need to pump some voltage in that thing.If you can't run 1.5v on a Hyper212+ your doing something wrong,or it is very hot in your house.

I can't imagine what i'm doing wrong. I have reapplied thermal paste multiple times.

That said, what is the best way to apply the paste? I have read several threads but haven't actually reached a conclusion.

I'll pump 1.5 into it now and see what happens :3 Also, i would add more to my NB but because of the powerphasing on my motherboard it is recommended i first add a mosfet heatsink

Check your VRM temps
They may not necessarily be causing blue screens but could possibly be of some concern
post #26 of 46

Would the VRM sensor be the same as the general MB sensor? If that is the case, i get about 25°c constant.

I can get an H70 this weekend if i choose but it seems like the Hyper212+ should definitely be able to handle my temperatures. As of now i am running 3.9 @1.392vCore. It seems so weird that i need another tenth of a volt just for an extra 100mhz.

FrozenCPU.com is taking forever! I ordered my items nearly two weeks ago and all that i get from the UPS tracking site is "Electronic Shipping Info Received." :@

Thanks for your help so far. After downing my HT multi, Prime95 lasted just a little bit longer before i got a bluescreen (Around 10 minutes.)

Does anybody know what generally causes each type of error? (E.g. BSOD, black screen restart, CMOS corruption et cetera)

Just my two-cents...

I needed 1.44v to get 20x200 on my 955 C3. Try 1.5v or even 1.55v. If you can't get that, something else is going on (and, I hate to say it, but it might just be your chip). Try to keep your RAM at stock settings, your NB and HT down (2000Mhz) while testing the CPU.

I'll retry, using clock multi and higher voltages. Thanks, all these two cents will make a dollar eventually, which will hopefully culminate to 4ghz

No problem. Perhaps go with a 20x200. That's nice and easy and should allow you to use simple multipliers on your RAM, HT, and CPU/NB.

My biggest weakness with overclocking is wanting to get everything at once (e.g. CPU, NB, and RAM). Go one-step-at-a-time in order of what's important to you. Start with the CPU, then the CPU/NB, then the RAM. It's all about the journey.

Good luck!
