Overclocking (Main Thread)

So, am I out of the running too? 😛
Going from 1.8GHz up to 3.6GHz on an E2160... wouldn't you say that's a pretty significant percentage increase? 😁

Anything over 95% isn't even in the running

So, after messing around with Snagit for the first time, I think I finally have it down.
I spent a little extra time tweaking things because I was obsessed with trying to force my workflow under the 10-second mark.

Give the memory another shot...

Everest says:

488.8 x 9.5 = 4643.4
overclock - 47 %

I swapped back to the OCZ memory (960, timings 4-4-3-15). I couldn't push this Geil 1066 any further than a 20-25% bump, which isn't much to brag about, and the timings are worse than the OCZ anyway.

The GPU is here—a brand new ATI Radeon HD 4850—but I'll be installing it in the next few days. Finally, the Dell will actually have some real power behind it.

I decided not to sell the motherboard after all, even though I’d already promised the whole combo (Motherboard, CPU, RAM) to someone. Instead, I'll just buy them a Gigabyte for the same price.

Who knows how far I can actually push this thing with overclocking.?!
Basically, how high can I push the voltage? I've got the Intel Core 2 Duo E6750 up to 1.6 V so far.
Long-term, I want to stay consistently above 4 GHz. We'll see how much voltage that requires.

The cooler is a Thermalright Extreme (or Ultra, whatever the hell it's called).

Looks great. What's the CPU temperature running at?

I've got two questions for you guys here:

First off, what should I run to pin the CPU usage? (I’m guessing some kind of stress test or number crunching?)
I probably need to keep an eye on the temps during that. If I remember right, they were sitting around 35-40 degrees.

Second, how's that Validation coming along? I might run it myself just to make sure everything is actually following the rules.

Third, what's the ceiling for the Vcpu on this chip?

For stress testing—use Orthus

To get your Validation done, you just need to grab the latest version of CPU-Z, head over to the very last column labeled [about], click on [validation], then hit [save validation file]... just make sure you don't rename anything before you click [save]. After that, you just upload it right here http://valid.x86-secret.com/ and well, you know the drill from there...

As for temperatures, I always recommend checking them using real temp settings...

When it comes to voltage, for a 45nm chip, I’d say a Max Vcore of around 1.45V is the sweet spot, though if you're feeling particularly daring, there really aren't any hard limits out there...😬

By the way, I used to push my Intel Core 2 Duo E6700 up to 1.75V back in the day, but personally, I wouldn't dream of pushing a 45nm chip past 1.6V for a benchmark run...

Had a little fun playing around, but it was a bust. I can't even get things to spin up... it crashes once it hits 72-73°C.

Motherboard: P35-DS3 rev 1.0 - the voltage regulation is pretty rough; after 1.60V, the next step jumps all the way to 1.80V (though maybe a tiny bit lower actually).
Cooler: stock

Validation: http://valid.x86-secret.com/show_oc.php?id=420267

The motherboard is a bigger culprit here than the stock cooler, but hey... it is what it is. At least the clock speed is decent considering the hardware I'm working with.

EDIT: I could probably squeeze out a slightly higher clock, but without some serious cooling, there's zero stability. No point in chasing it.

Dad can handle the stress testing—inter thermal analysis tool

E8500
Geil Black Dragon 1066 2x1 GB

485 fsb x 9.5 = 4607 MHz

Super PI = 10.094

Vcpu = 1.525 (Everest 1.51 V)
Vmem = 2.30 V

Not bad at all...
I've got my E8400 running at 1.315V—no issues there. It holds steady at 3600MHz without any trouble.

I'll try pushing the memory one more time—maybe it'll decide to cooperate and hold at CL4 this time.

Anyone got a clue?

I'm rocking an ASUS motherboard with 2x1GB Kingmax 800MHz sticks and an Intel Core 2 Duo E6300 @ 1.86 GHz (266x7).

I bumped the FSB up to 333, which gets my CPU running at 2.33 GHz totally stable. Temps stay under 60° even when I'm pushing it. But the second I try to nudge that FSB any higher, the PC just refuses to boot. I tried cranking the voltage all the way up to 1.5V, but no luck. I thought maybe the RAM was being picky, so I dialed it back toward the stock 800MHz speed, but still nothing. Even dropping the memory speed below 800 didn't fix it.

It’s driving me nuts because I see people all over the forums and tech reviews bragging about hitting over 3GHz on these chips without even touching the voltage! 😕
What am I missing here? What am I doing wrong?

Which specific P5B motherboard are we talking about?

Have you tried dropping the multiplier?

What’s your max FSB looking like?

The multiplier isn't actually the issue here; we're looking at 7!

Hmm, the P5B should be able to push past that 333 FSB, and honestly, it should hit 400 without breaking a sweat.
Why not try bumping up the NB voltage? Moving from 1.25 to 1.40 might just be the stability boost you need.

The Motherboard is this one.

Multiplier's sitting at the stock 7. My BIOS is only giving me 6 as another option, which I haven't messed with yet. But wouldn't that just tank my CPU clock speed?

BIOS lets me push the FSB up to 650 MHz.

Here’s how the Intel Core 2 Duo E6300 is performing on my rig

2304.05 KB - BMP 😲

And there's actually even more to show you.... maybe 500x7 more...

Wait, what am I looking at? A 61% overclock with a core voltage of only 1.212V?!! 🤣

@wiredmarlin5 of course it works


I've got C1E and EIST enabled, which is why CPU-Z is showing a multiplier of x6
Honestly, if I actually had the patience to mess around with memory timings and the FSB, I might try to squeeze out a slightly higher FSB😁RAM.

@Jason Chase10 😕

A standard C2D usually sits around 1.3V, but based on that screenshot, you’ve got your overclocked chip running at 1.212V.

Could Everest just be tripping?
