Description

This was the first time I had overclocked an Intel CPU. Unfortunately I do not have photos of the build.

Here is what happened.

Lets go back to November 8, 2007.

When I originally got my system I tested outside the case and was able to get a 2.8GHz overclock from the stock 2.0GHz at stock voltage. Once I discovered my PSU was bad when I put it inside the case I decided when I got the PSU back last week from RMA I would run it at stock for a while. So today I got the urge to OC it again. I tried putting it to 2.8GHz but it crashed on loading windows. So I decided to start off at 2.6 and here is the story.

Setup: MB: Gigabyte GA-P35-DS3L (Rev.1) CPU: Intel Pentium Dual Core E2180 @ 2.75GHz (M0 Stepping) CPU Cooling: Stock Intel HSF RAM: Mushkin HP-6400 PC2-6400 DDR2-800MHz @ 825MHz 4-4-4-12 2T GPU: XFX GeForce 7900 GS Extreme Edition GDDR3 256MB 256-bit (G71 GS) @ Core - 480MHz / Memory - 1400MHz NB Cooling: Stock SB Cooling: Stock PSU: Corsair VX550W 550 Watt HD: Seagate 250GB 7200rpm 16MB SATAII OS: Windows XP Pro SP2

Ambient Temperature: 19-20°C CPU Temperature: Core 0 27°C / Core 1 28°C @ idle Core 0 36°C / Core 1 40°C @ load

Overclocked to 2.6GHz It was stable running Super PI

Overclocked to 2.7GHz Again running Super PI it's stable.

Overclocked to 2.8GHz It crashed loading windows at stock volts.

Overclocked to 2.75GHz Ran Super PI it was stable.

3DMark 06 Test I was surprised my score wasn't higher I do not know what is bottlenecking me.

Benchmark Settings Resolution: 1024x768 Anti-Aliasing: None Texture Filtering: Bilinear VS Profile: 3.0 PS Profile: 3.0

Selected Tests SM2.0 Graphics Tests - GT1 - Return to Proxycon - GT2 - Firefly Forest

CPU Tests - CPU1 - Red Valley - CPU2 - Red Valley

HDR/SM3.0 Graphics Test - HDR1 - Canyon Flight - HDR2 - Deep Freeze Conclusion

I am currently at stock voltage of 1.2 vcore and I since I only have the stock Intel HSF I do not want to up the voltage until I get a better cooler. For right now 2.75GHZ from 2.0GHz is a decent OC for me. I have not ran Orthos yet but I will tonight when I am at the hockey game and see if it is truely stable at 2.75GHz.

How the hell could you oc that pentium?

LGA775 uses FSB to OC locked CPUs,

like the CPU was running 200MHz FSB

bumping up to 233MHz = 33Mhz x10 = 330MHz jump

FSB can be a hit and miss affair since it also affect RAM and PCI-E speeds

note that FSB OC depends on the chipset

You can add voltage, even with a stock cooler, so long as you are staying within thermal limits. It is no different than overclocking with an aftermarket cooler, you will just hit a thermal wall much sooner.

Also, Intel made much more stout CPU coolers back in the day. I would say just follow the simple rule of keeping temps under control and you should be fine.

Good luck bro. I love these kinds of stories.
