Ah yeah, those Zalmans are a joke. I can't believe I didn't look harder before I bought it I usually research things pretty extensively before I buy but I made a huge mistake. Hopefully the Tuniq will lower temps 7 or 8C and if I can hit 3.4 stable at that, I may lap it to get another 2 or 3C, but thats only if Im convinced its not a terrible OCer, which right now I am not...

Thumper that is some good info with the vdroop, I didn't think about it like that but that makes perfect sense.

Skeegle,

Here is a link to a post that I made yesterday, it is settings that I have used to achieve a stable OC at 3.4 GHz.


Hope it helps, when you are ready!

Hogans that looks awesome. Ill boot up with those settings as soon as I get my Tuniq installed, I don't want to even think about loading temps with this zalman. Thanks man.

Alright so my Tuniq and PSU came and I have them hooked up, but, I found out that the reason for my poor overclock was because I was basing it off of TAT temperatures. I didn't know that loading temps of TAT are seriously like 10C hotter than real world loading temps. What I mean is I OCed to 3.4, ran TAT loaded both cores and my temp was 65C. Then I ran an insance of Prime95 on one core and Super Pi 32M on the other core to achieve 100% load, and my temps never went above 54C. To make sure I was seeing things correctly, I closed Prime and Super Pi and ran 3dmark06 with TAT open logging the temperatures, and once it was done I scrolled through every temp recording for the duration of 3dmark06 benchmarking and the hottest it ever got was 56C, and this was clocked at the same speeds and voltages that TAT read 65C. That means that gaming, computing, etc will never get close to 60C which is the limit on conroe, so I think really I was fine all along. I clocked mine to 3.66ghz to get my 1ghz OC and it is 100%stable with temps occasionally hitting 61C at full load while gaming. Overall, it was TAT effing up my clocks, not the chip. So now I am running this setup 24/7:

3.66ghz with 44C idle and 59C load.

Skeegle,

WOW, nice job man!

You may want to decrease your OC and Vcore some though, those temps are pretty high.

One other piece of advice...did you ever consider lowering your multi and raising your FSB? That worked wonders for me...That mighthave already been in there, but I thought I would add it.

@hogans: I dunno man I think my temps are alright, they're below the recommendation, and considering I load less than one hour a day I think they're fine.

@Hiba to achieve the same internal clock you had lower temps with a lower multi?

first, open your neo550 manual. put your hardware on the right rails. ie video card on its dedicated rail and etc. that will eliminate variable #1 undervoltage.

second is variable #2, check your mobo temp. if it loads at 50 then the answer is simple. put your finger on your NB. if it burns you (which i think it will) then buy a 25$ NB cooler. don't skimp an get one of those 5 dollar aluminum zalmans. and yes you must take off that ridiculuas NB heatpipe. if you examine it, you will notice it is not working anyway.

third, replace that SB heatsink with a cheap 5 dollar zalman chipcooler from newegg.

fourth, if you are on stock cpu stock cooling, stop it. get a asetek microchill, tuniq tower , BT (watch out for space reqs), if you are short on cash settle for an artic freezer pro. of course don't forget the AS5

Thats it. put your bus termination voltage at 1.2. Play with your cpu volts and you will soon be at 3.6 -if you want more, go water cool.

lastly and very importantly, your corsair uses promo chips. leave him alone. run him at his stock speeds. 400 bus with stock timings. He cannot overclock. his range is +/-10%
reason: sometimes people get xms2 6400 with micron chips (thats how they clock it up) if your mem is fast and stable, leave him alone and let him work.
