Good overclock result?

Ok, this is my setup, and I need to know if my overclock yielded good results.

STANDARD:

P6N Sli Platinum
E6550 @ 2.33ghz
PCI-E Bus @ 1500mhz
FSB @ 333mhz.
Mem Bus @ 800Mhz - Dual Channel 400mhz

OVERCLOCKED:

E6550 @ 3.24ghz
PCI-E @ 2950mhz
FSB @ 463mhz
Mem Bus @ 868mhz - Dual Channel 434mhz.

My CPU temp idles at 21C, with 34-36C under load. The system is stock air cooled. Case has good ventilation and dimms are cooled using heat spreaders. Where should I change next? Should I up the FSB some more and see where I start to get BSOD?

Just how far can I still push?
 
just out of pure interest - what intel chip out there can give you the BEST overclock with stock cooling - and recommend a mobo with that chip
 
Using Speedfan and Duel Core Centre (MSI) that came with my board. They both correspond.
Stuck a thermal sensor to my heatsink to make sure, seems correct. Sensor displays a difference of about 0.5C.

Killadoob, if you say I can get more out of that CPU, do I up only the FSB? In what relation should the CPU and RAM clocks be running?

Latest coretemp ^^^ version 0.96.1. Its temps on my E6550 is ~16C higher than speedfan 4.33.

coretemp: 33C Idle
speedfan: 17C Idle

E6550 @ 2.4GHz (when under load the multiplier goes up from 7x to 8x giving me 2.8GHz) with stock cooler, 1.22V core.
 
OK, so these are the respective temp readouts.

--SpeedFan--

CPU Temp : 25C
CORE1 : 12C
CORE2 : 13C

--Dual Core Centre--

CPU Temp: 25C

--Core Temp--
Core 1: 26C
Core 2: 27C

--P-Tuner-- (Temp Sensor plugged into my PSU, and stuck onto CPU heatsink)
Temp: 26C

So which one do we trust? These temps are at idle. E6550 @ 3237.5Mhz (As per core temp)
 
Core Temp Log Entry for CPU under stress:

1/22/08 5:49 - 3237.5 - 51 - 52

Are these acceptable temps?
 
The load temps would probably benefit from a better cooler but they are fine as they are atm. My bro's office PC has a Q6600 and the one core goes up to 65C under load @ stock. I think you only need to really worry about temps when they reach 70C. Cooler is always better though :)

Have u benchmarked it? What GFX u running? IMHO u should have benched before and after oc'ing, to check the performance difference. Maybe post yr 3mark06 score here?
 
I actually did. 3DMARK06 v110
GFX = 8800GT 512 MB.

Pre Overclock: 10147 marks
Post Overclock: 12087 marks
 
Yeah it would have been nice to see the 3D mark difference but I'd say your overclocking wasn't bad. Nice job.Your first time?
 
Yeah, first time. This is as far as i've tried to OC it. My goal was 1Ghz, and I got there. I'll keep it at these specs for the moment. Dont want to push the stock cooling too far.

That's actually pretty good man, quite a big jump after ocing. I say if yr PC is stable after oc u must leave it there, unless u wanna punish the quad :p
 
OK, i found my system was unstable under a CPU stress test. Problem was the RAM.
I finally got it stable by upping the Ram voltage to 1.9V. After a 3 hour CPU stress test, all seems fine now, and I ended up with the following specs on stock cooling.

MOBI: MSI P6N Sli Platinum
CPU: E6550 @ 3.316 Ghz (Max core temp 52C)
RAM: 800 Mhz (Stock)
PCI-E Bus: 2925 mhz
NB Voltage: 1.3V
RAM Voltage: 1.9V
V Core Voltage: Stock + 0.0125V
GPU Core: 705mhz
GPU Mem: 2020mhz

--The 3DMARK06 result--

SM2.0: 5933
HDR: 5698
CPU: 2913
TOTAL: 12648

Not to shabby. I'm quite impressed. Thanks for everyone's input and help with the temp monitoring etc.

You could come down on the PCI-Express bus speed, it won't make that much of a difference, try benchmarking it with stock and overclocked setting and see what the results are.
