Ok, then...first of all, many thanks for sticking around and helping me, rx7racer, I really appreciate that! thumb.gif
I'm starting the procedure.
First of all, I'm posting here the values I start with, just for the record:





Then I'm off to thinker...I will report here in a bunch, I hope...wish me luck! tongue.gif

Ok...turns out my MB has some kind of OC presets built in....biggrin.gif
Question is: would that be safer using such presets, instead of manually thinkering, or that's the same deal?
For instance: I took the 10% OC profile, and got a 2.196,27 Core speed, with a 6 multiplier and bus speed to 366,04, rated FSB 1464.18Mhz...DRAM frequency is up to 493,3...I guess this did something...



PC booted fine, and so far temperatures look fine as well...I'm quite curious about the higher presets...or would you recommend manually tweaking things?

Well, I did some more exploring....
I tried rising the BIOS OC preset to 15%.
PC booted veery slowly, and I got to some 3.06Mhz, peeking with CPUZ I noticed DRAM was up to 480, I (somewhat stupidly) got scared and quickly went back to the BIOS.

Then I decided to play a little bit with the presets:
I noticed that if I load a preset then switch to manual values, I can see what the preset loaded and alter each value at will, or leav it to default "AUTO".
As of now, I went back to the 10% OC values, then peeked: 10% OC value, for Asustek, is 366 FSB (did not look the other values, I'm making a mental note to do so and write them back here).

I tired rising FSB to 375, while leaving all other values to "AUTO" (presumably set to the 10% preset? Need to investigate this).
Windows booted, and here are the results:

Core speed fluctuates between 2251.25 and 3001.95 (multiplier rises to 8x when needed, then goes down to 6x, this is what CPUZ shows).
Temperatures are decent, but I did not test it under stress...
FSB:DRAM is up to 1:1, while in the 10% preset they were still 5:6.
System feels a little laggy, however, so I guess my work is not yet done...rolleyes.gif

Any suggestions, while I investigate the default values? That 10% preset felt pretty safe and optimized: system booted balzing fast and felt fresh, but now I tasted the forbidden fruit, I want more! tongue.gif

Edit: I'm now back to the standard 10% OC profile (2196.23 to 2229 Mhz, with some spikes to 2900something, multiplier fixed to 6x, FSB:DRAM reads 5:6, RAM freq is at 439,3 Mhz)...boot felt slower, this time, so I'm guessing the fastness/sluggishness was probably not all due to the OC operation.

Here are my BIOS values, right now:
FSB freq: 366
PCIE freq: AUTO
DRAM freq: AUTO
Memory over voltage: AUTO
NB overvoltage: AUTO
CPU VTT: AUTO
SB 1.5 Voltage: AUTO
CPU core offset: AUTO
Phase operating control: AUTO

I checked and found out I cannot peek what the other preset values are: I can only peek FSB, so I'm quite at a loss...should I pop it up again to 375 and alter something else then stress test my system? Or should I attempt something more? (I tried a 15-minutes run of OCCTPT, and temperatures went up to 63-65 degrees, which should still be acceptable, if I'm not wrong. Of course, before doing a whole 3-6-24hours test, I want to be sure I cannot do better than this...).

I'm back behind the keyboard, after a night of sleep and pondering...
I finally found the setting for my multiplier (for some reason, the ASUS P5QL/EPU BIOS stores its values in separate pages), and set it to a fixed 8, so the clock does not bounce to and fro 6-8.
Afterwards, I found out my BIOS has some kind of pre-sets for DRAM values as well, so I don't need to input values manually. I chose the lowest option (750, which I assumed to be DDR value for 375), so to achieve an FSB:DRAM ratio of 1:1.
Having done this, I set back FSB to 375, saved and rebooted.
OC seems to be working fine: Windows started at decent speed (I won't be fooled again, I know this is not entirely related to the OC operation, still things seem smooth enough).
Here are my new values (as you can see, I was right about the DRAM value):



Since things seems to be quite stable, I'm testing this configuration, before I consider going further on. tongue.gif
I will report back here after some hours of testing. Feel free to post comments and/or suggestions in the meantime...I'll use the testing time to read them, as well as to read something more on OC from my tablet. biggrin.gif

Update: I ran OCCT for over 2 hours (from what I read, that's the recommended phase, before attempting a longer test).
As you can see from the screenshot below, OC seems to be working quite good...I am however concerned about temperature rising up to 75 degrees (from what I read, it should be a no-no):


My readings lead me to think I should do something to the voltage, to lower those temperatures a little bit...am I correct?
As of now, my BIOS manages voltage automatically, so maybe that's heating things up. According to CoreTemp, my VID should be 1.2875v, if I'm not mistaken....
Before I start thinkering with voltage, however, I would like to have some insight on it, so I don't overdo it...I read my PC would not start at all, with a bad voltage, but I would like an advice on the matter...
Below are the CPU voltage graphs made by OCCT during the test, so you can see more about my possibility (they look like double-dutch to me...rolleyes.gif):








Oh, BTW, bit of an update...looks like my Motherboard does not have a CPU voltage setting....not in the traditional sense, at least...the only things I can see and alter seems to be the following:
DRAM freq
Memory over voltage
NB overvoltage
CPU VTT
SB1.5 Voltage
CPU core offset
Phase operating control

All these values are now set to AUTO...any suggestions about that?

A quick edit: I read around another tiny bit, and I found THIS GUIDE about "Overclocking Using Offset Mode for CPU Core Voltage". It seems to be my case, but, before screwing things up, I'd like to hear some confirmation, or at least some opinions about this, especially since I don't see any load line calibration setting in my bios...tongue.gif
For the moment being, I saw I can change those offset values only in positive. Just to start, I removed the "AUTO" value, and put it to 0.

Here's an updated screenshot (I noticed my last one was in standby, so you could not see I had positively reached 3.0 smile.gif ) :
