Took my E6600 out of my DS3 c1 mobo to test my E6400....Now along comes my S3 mobo which was intended for the E6400. So I decided what the heck throw the E6600 in.....

At 3.4ghz 1.47v actual it dual orthos stable and only hits temps of 52c (core temp says 58c).....

Before I was only able to hit 3.26ghz @ 1.46v actual and the temps hit near 58c in orthos and core temp said like near 70c. I have noticed the DS3 temps are wider spread using easy tune then the S3 mobo when comparing to core temp.

Also before I could not get 3.33ghz stable even at 1.5v.

Ram is different in this board but I tested same speed on the DS3 using 3 different sets of sticks and there was no different. i was successfully able to isolate the ram with loose timings that it didn't effect the cpu...I kept ram at loose timings at first but then turned the ratio to 2.5x and I am currently running ram ay 945ddr2 with cas 5-5-5-15 using Ballistix PC2-6400 sticks

Other differences....

1) I used AS5's website to find directions on how to apply for dual core....No longer one dab in the center...It is apply a bead in a line in the direction of the cores under the IHS....May have made a big difference casue my temps of my E6400 are very low as well...

2) Both have OCZ 600 watt Powerstream PSUs, but the one with the S3 shows stronger 12v rail with little movement though 3.3v rail is a tad lower....

3) The DS3 has the supposedly better Ninja Scythe w/ 120mm fan while the S3 and the E6600 has the scythe Mine with 100mm fan.

Running dual instances of Folding at Home

E6400@3.43ghz 1.46v /DS3 = 40c (51c coretemp)
E6600@3.4ghz 1.47v /S3 = 40c (48c coretemp)
E6300@3.43ghz 1.47v /S3 = 49c (58c coretemp)



Overall very happy with the E6600....Now I have 3 different cpus all OC'd within 30mhz of one another at near identical voltages....


GUess I will sell the E6300 (runs the hottest) to pay for my QX6700 ES I just got for 650 dollars!!!!! :Q

LOL @ the S3 doing better OCs that the DS3.

I still remember how i was considering the DS3 initially...man i have not regretted deciding against it & spending more for my trouble-free P5B-D :p

I find that oddly enough, my E6300 idles higher than my E6400 with voltages all identical. Weird you are finding your E6300 runs hotter too.

Nice score on the QX6700 :Q

I have no need for quad core yet, but that seems like a good price.

F6 bios came preinstalled on the S3 mobo from Newegg...i believe that is still themost current...

F7 bios onthe DS3 was used...F8i was tried but stability issues caused me to return to the f7 bios

The DS3 is not the best board ever designed. The S3 seemed to actually tun out better. having said that though I had no problem clocking a DS3 to 475*8...

I just updated to F6, I seem to be stable at the moment at 475 FSB with my e6300 now, I was having trouble getting stable past 450 with F5... strangely with +.4 & .5 vDimm I was crashing in super pi, lowered it to +.3v and it's making it through...

How in the world did you get a QX6700 for $650..that seems like a steal....

there are two temperatures listed there. does core temp not report the true temp? if so, whats it reporting?

I believe Duvie mentioned that it was a used Engineering Sample he purchased, hence the "ES" at the end of the model.

E6400@3.43ghz 1.46v /DS3 = 40c (51c coretemp)
E6600@3.4ghz 1.47v /S3 = 40c (48c coretemp)
E6300@3.43ghz 1.47v /S3 = 49c (58c coretemp)

Amazing how three diff CPUs from 3 diff price ranges all OC the same! ;) Glad I bought a 6400; for the 8x multi, of course.

Your temps on the 6400 are just outrageously good, man. You make me ill. :p

I applied the AS the new way, and have been thru two thermal cycles (powered off for about 24 hours each) already. After about 6 days now, my idle temps are 51/53. Stress never breaks 58C.

But, my PC is QUIET. Oh, such sweet quiet-tude. You literally can't hear it from more than 6 feet away. I'm sure if I put the exhaust fans on MED, I could get the temps to drop...but then I'd hear the PC and who wants that? Heh, this coming from a guy who used to have a crack rack with motherboards and HDs just sitting on a shelf with a desk fan blowing on them...
