The idea of small FFTs is to fit neatly into the cache registers L2/L3 and would be more stressful for the cpu with load of heat being generated. Always good to run "Blend" for an extended period,  at least a complete cycle or up to 12 hrs as I do to stress the IMC on the cpu. I've been using Prime 95 for years and it is the best overall stress test IMHO. Couple of notes:

FYI,

"You can control which FFT sizes are tested by the torture test.  In prime.txt
you can set:
   MinTortureFFT=n
   MaxTortureFFT=m
Where n and m are in "K".  The default for n and m is 8 and 1024 which will
run tests on FFT sizes rom 8K to 1024K.  Set n to 8 and m to 16 and you will
run only small FFT sizes.  These FFTs will fit in the L2 cache and may be
more stressful to the CPU."

You can control how many minutes each FFT size is tested by the torture test.
In prime.txt set:
   TortureTime=n
The default value is 15 minutes.

"you can override the info in local.txt:
   NumCPUs=n
   CpuNumHyperthreads=1 or 2
   CpuSpeed=s
Where n is the number of physical CPUs or cores, not logical CPUs created by
hyperthreading. Choose 1 for non-hyperthreaded and 2 for hyperthreaded. Finally,
s is the speed in MHz."

Finally, from the WiKi below, some good info on FFTs for your viewing pleasure (boy how I recall this from my collegiate days ):

Great info! Did you get your ssd yet?

Great info! Did you get your ssd yet?

I did but I'm awaiting my 980X from Pinheads Direct

I'm on a backup rig since I sold my 920.

Was wondering if this could beat the dual Xeon.

that was at 4575 with mem at 1950 or so 8-8-8-24-88

Sweet! what clocks christefan?

Currantly at 135x35 for 4713.x, memory at 1616 7,7,7,19,59,1T. Happy with the VTT, I'm at +125, but I'm pushing 1.4875 vcore without droop right now which worries me--the temps are in good shape through so I guess only time will tell for all of us enthusiasts what this cpu will really handle for voltage settings and if it is really like the earlier i7s-- best wishes with your clocks-

This is my 24/7 @ 4.5Ghz.

Well i think i found a cure for the Gflops

What did you do to fix it??

I'm waiting on mine from them too. I finally received confirmation that it shipped, and I should have it on the 1st, how about you?

Ht off is smoking fast with 6 cores

Ehh, I'd rather buy something from Guido in the alley than Nimrods Direct.
Sorry Gov. hope it gets to you soon!!!

He canceled his order a couple days ago

I run mine as high as I feel temps can remain under control which also translates to voltages that aren't sky high because if the volts were that high I couldn't keep control of the temps with just good water cooling.  I'm at 4713.x with 12 threads and will test 6 cores/6 threads as soon as I get some spare time to see if the higher clock allowed by turning off HT gives me better performance in general for the stuff I do must of the time--good luck 

Went ahead and took screenshots

thank you emmett, that is very informative. I am going to go buy a multimeter tomorrow i guess. Im sorry if this is a "noob" question,  but how do you know exactly where to put the multimeter, is it labeled on the motherboard?
 
edit: I also have the evga 760 and 980x proc. I figure if the multimeter does in fact show 1.35 tomorrow after i buy one, then maybe theres a bug with the evga 760, since it seems to be happening to you also.

Edit: I sent this to you in a private message, but im not sure if its going through so i went ahead and just posted it here.
 
Hey Emmett,  Here is a picture of the multimeter interface that i bought.

Ive never used a multimeter before so i just wanted to double check. I have read through the manual and if im understanding correctly, i want to use the symbol that looks like a V with a solid and dotted line above it? Or am i wrong? Also, im guessing its pretty straightforward, Just touch the black to the ground spot on the motherboard and then the red to cpu vtt for the reading?
 
Thanks for your help

When did you order? I ordered on the 22nd, Monday last week and they were out. I canceled the order this past Monday now everyone's out, Newegg, ZZF at least until the 5th. I hear ProVantage may have some this week, one can only hope.

I can't do it but I ran this out of the box and I'm happy
About the same as garnetandblack on pg 2 but with 12gigs--- 20 passes LinX and 4 hours prime is good for me as well!!
