Not required, but makes your overclock resume look better.

A 1hour blend with 75% memory usage is plenty. thumb.gif

Ah, good to know. Thanks!

So, to save time, I could just run a small FFT test for a little while first to see if it's going to over heat. If that works for a few minutes, I can run a much longer blend?

no because blend runs all of them, it just takes longer to run trough everything. thats why it is advised to run for 12h+ at least so you run through enough FFT's to make sure your stable. if you test for 1h, you should have only ran 4 different FFT's ( out off 70 ). the ones you did run in that one hour should be 448k, 8k, 512k, 12k. there are some certain FFT's that will consistantly make your cpu crash while it might be perfectly stable on those first 4. what you could do is run prime for 1-2 hours and then up vcore by a little bit to make up for the bit you arent sure about. obviously this will give slightly higher temps. if you want the lowest possible stable voltage you'll really have to test for 12hr+(and preferably trough the entire list)

OK. I ran small and large for over an hour each. After that I ran blend for almost 12 hours. The guide said an hour pass should be good.
Reading between the lines it sounds like while u r testing and attempting to get your highest clock, u should run an hour. After u pass 1 hour on small and large, then run blend for 12+ hours. That's how I understand it.
Anyways, thanks again for all the input.

For casual use, I haven't seen any problems yet. When running Prime95, it runs for 15 minutes with temps in the 70's and 80's. Then right around the 15 minute mark, the temps shoot up. I have Core Voltage auto shutdown at 95 C and it shutdown. It's done this twice, so Prime95 must be doing something at that point?
Are the first 15 minutes of Prime95 just warmup and the real test starts at 15 minutes in? I'm just wondering if some new thermal paste and fans might be enough to keep the temps down, or if actually there is a much bigger hurdle.

I hit 95-102 on one core yesterday and it didn't shut down on me.
1.4312 is a lot of voltage as well I am having temp problems at 1.36.

Whoa that's a lot of voltage. What are you clocking at and what cooler are you using? That kind of voltage should only be used for watercooling and having it past 90C is cutting it too close to max temps.

Edit: I see that you're using a Corsair AIO cooler, I would suggest lowering your voltage to below 1.3v and see what kind of clocks you can get out of that. I personally wouldn't go past 80-90C on a CPU.

why are you trying to kill your chip...just try to get the highest OC you can under 85C, using the least voltage possible (i would say 80C, but you seem to be pushing it)..and call it a day...it's not going to make any real world difference...some people are too obsessed with seeing the highest number possible in CPU-Z...when the side effects aren't worth it..

O well..I guess I am on OCN..what can you expect. Ignore, and please continue.

The software "Core Temp" has a nice auto shutdown feature. So when I said it shut down on me, it's because it hit 95 C and I had it configured to shut down at that temperature. That's what I want. Just in case I'm not staring at it and it goes hot for some reason.

I haven't touched my RAM at all, so why does increasing my CPU's turbo voltage screw with my RAM?

This one is still confusing me. Can someone explain why increasing the turbo voltage and multiplier on my CPU would affect my RAM?

According to this guide, or somewhere I was reading on these forums, the increased speed of the CPU may tax the RAM more and so need a little voltage boost to handle it.
