Hi guys, (not sure this is correct place to post)
well i never done OC before, so not sure how to do this.
could anyone have good introduction of how to OC the system?

here is my parts:

CPU: intel i7-2600k
MOBO: ASUS p8p67 pro (rev 3.1)
GPU: EVGA GTX 560 ti 2win
RAM: G.Skills Ripjaws Z series (4x4gb 2133)


2nd question:
I use H100 cooling now, and not sure why temperature reading is different from BOIS and SPECCY program.

BIOS: CPU high 40C's, MOBO 20C's
SPECCY: CPU low 30C's, MOBO 60C.

is there a good temperature reading program?

please help me.

Thanks.

for the 2600k, you just bump the multiplier and nothing else. anything else could be dangerous for the hardware.

Good temperature reading programs are HWMonitor and Realtemp. Realtemp is most reliable (more so than the bios).

Not familiar with RealTemp, but I've been using SpeedFan and its pretty comprehensive. If the hardware has the circuitry for it, it allows speed control of case, CPU or gfx fans incrementally and according to various customizable temp thresholds.

The advantage with realtemp is that it compensates for known inaccuracy in the sensors.

I'm gonna check into that. Thanx for that.

Speedfan has the capability to establish offsets for any monitored sensor, i.e., fan speed and temp. For example, my HDD's need temp offsetting to get them in synch with what can be discerned through SMART (which I'm assuming to be accurate).

Good thing you brought that up. Right now SpeedFan is reporting 37 Deg. C. for HDD 0 (SMART is reporting 38 Deg. C.). For HDD 2, Speedfan reports 37 Deg. C (but SMART is showing 34 Deg. C.). So I alter the temp off-set for each HDD and I'm at least in the in-field of the ballpark.

Also, its necessary to change the fan-speed ratio for my gfx card (otherwise it displays too high a value).

Again, this is not nuclear engineer tolerances: ball-park infield be guttenuff (as they say in German). You KNOW when a homerun's been hit out of the park; that's when to stand up and take notice something be awry.

@Hurrycane

The CPU temp value in BIOS is a close approximation of 100% CPU load.

Whatever temp-monitoring tool you use should show values at least as high as what is shown in BIOS when the CPU is at full load, e.g., Prime95.

However, when the CPU is in fact idle, temps should fall off dramatically, i.e. lower 30 to upper 20 Deg. C. A good rule of thumb for idle CPU would be ~10 Deg. C. higher than ambient; that baseline temp will increase proportionately to O/C and voltage bumping (carefull w/voltage Eugene).

You should examine specs for your CPU and discern the max voltage allowable. NEVER implement max voltage. As you increase O/C freq, you will eventually discern errors, e.g. BSOD, system unresponsive, etc. Either you'll have to back off the freq O/C, or kick up the voltage. In either case the CPU idle-temp will increase.

You NEVER EVER want the CPU 100% load-temp to exceed CPU temp design limits. IF you find your 100% load temps at design limits, you need to consider alternative cooling solution.

That being said, notwithstanding and all that, you need to take into consideration your memory bus-speed also (can your RAM sticks handle the O/C with the RAM timings established in BIOS) if your mobo-BIOS can run CPU/RAM asynchronously.

Also, there are issues w/respect to FSB and PCI bus speeds. If you're mobo can't run CPU FSB / PCI bus aynch, there's a point where you're overdriving you're peripherals, e.g. RAID, sound, network cards etc.

A lot of things to consider when O/C'g. Not the least of which is that you'll void the mfg warrany, and most likely decrease life expectency of major system components by 50% These days that doesn't mean much though does it? How long do you want to use the components of the system that you're using today?

Presently I'm running on a P-III 1400-S @ 144 FSB, 1.58vCoreA (53C @ 100%).

When this system goes belly up: I buy brand new - in the box & shrink-wapped - top of the line 2007 technology for $20 / component and I'll O/C the crap out of it too.

@kris23, thanks, i will look in to that.
@WxMan1, I think i found right program for mine for reading temp.
there is ASUS MOBO CD that come with this program and reads the temperature for me.
and it's in high 30C's.
so im guessing that is correct one.

blibbax

Motherboard temperature readings are notoriously erroneous. Mine often under-reports by 20 degrees or more. This is because they measure the package temperature rather than the core temperature, which tends to be a lot hotter.
