Unfortunately, the retail shops around here are incredibly overpriced

I think anything in the low 30's with a B week is good.

I just got a 31B E6600 that does 3.2 on 1.26

My E6400 (26A) always needed 1.55v to obtain anything over 3.2. Between 3.0 – 3.2, 1.45v was still needed to obtain a long-term ORTHOS. If I was ok with a few hour run of Prime then even lower voltage would be ok. Again, long term (27/7) Prime? Not possible without more voltage. The 6400 would clock at 3700+ MHz but not 24/7 stable even with 1.6+ volts.

The E6600 clock-for-clock is obtaining a higher value at the same voltage. At 3.5 it hardly drawing 1.45v and has past double prime plus for well over 12 hours. With 1.35v, it’ll run ORTHOS for a couple of hours before stopping.
At nearly 3.8GHz with 1.55v it would not prime for more then an hour.

So the E6600 is giving up an ‘easy’ 3510MHz, especially for water cooling. Temp are very low (idle +/-35ºc | working at just over 40ºc | load at just over 50ºc) with 1.475v

30 minute OCCT doesn’t mean the system is stable!

No "A" or "B" here either :\

Is this one of the better or worse weeks? D:

28A

3.24 @1.26v
3.40 @1.36v
3.60 @1.41-1.44v (depends on its mood at the time).

New prices are tempting, but waiting for the 45's.

I keep it at 3.6 24/7 with a load temp of 44c

Just curious, when you guys say 27/7 do you mean with a giant load on it or just running?

I put a big load on the machine when stable testing. Usually Orthos, OCCT and memtest.exe all at once. Sometimes I’ll even throw in a 3D Mark in a loop and let it go overnight. Its hard to let it go over 24hours because you can’t use the machine for that time. I’ve done it now and then when I was away for a few days – see if its still running when I get back home.

But I can obtain a somewhat-stable OC that will run 24/7 yet won’t pass a grueling series of snot-beating for more then a few hours. Technically its not stable since it can’t run Orthos, OCCT and memtest.exe at once for more then a few hours. However, its mostly stable in that it’ll run endlessly doing routine tasks.

I can drop the voltage on my machine quite a bit and still maintain the high clock as long as I’m not running double prime. If I’m not doing much and its hot out, I’ll drip the voltage and run the system in the gray area. But I believe that all to many posters on OC forums make ‘stable’ claims when in all reality there not. I’m not knocking anyone and I’m not being specific to any posts within this thread, just being general, but there is a distinctive difference between levels of stability that most people don’t address.

I became aware of this mostly from video editing. I’ll be working a job in Premier and using other apps at the same time to render and convert files I’m working with. This is like running 4 Orthos’s and a half dozen memtests. Temps will skyrocket and the tiniest but of CPU instability will lock up the system each time. Raising voltage is usually not an option unless I turn the room into an igloo but I find it hard to edit with my gloves on.
