Overclocking (Main Thread)

Roger Wright94 said:Man, you're asking quite a bit of me right now! If you stick to the stock voltage, you can usually bump up the FSB by maybe a few hundred MHz—say, 300 to 400.
I’ve got some solid numbers from my own testing, where I pushed it along these lines:
1.3 V - FSB 400 MHz
1.4 V - FSB 440
1.5 V - FSB 480
Those are just rough estimates. Since my main goal was hitting a really high FSB value, I just kind of eyeballed the CPU voltage increases as I went along.
I actually managed to hit 4 GHz using roughly 1.3 V, or maybe just a tiny hair over that.

I eventually reached somewhere around 4610 MHz. I'm just a few hundredths of a second away from breaking into the sub-10 range on Prime95. I'll give it another shot whenever the mood strikes me again.

So, what does it mean if it's not worth pushing past 4? Are you thinking it's because of the voltage requirements? Or just diminishing returns?
I just took a quick look at Speccy, and I'm sitting at 4200 MHz with 1.4 V. Honestly, I could probably dial that voltage down a tiny bit, but I'm not really losing sleep over it.

Yeah, once you hit a certain frequency, the performance gains in things like gaming start to taper off significantly... for instance, if you take a Core 2 Duo like the E8400 up to 3.6 GHz, you see this steady, proportional climb in speed, but after that point, you're lucky if you see a 2-3% jump despite having to crank up the voltage way higher... a buddy of mine had an 8500 that ran rock solid at 3.6 GHz on stock voltage... by the way, I'm not totally sure why you'd push it past 1.3V though...... it might handle 1.4 V fine for a moment, but running that 24/7 isn't exactly great for its health.... unless you're just doing it for a quick stress test to see how far it can go...

Hey everyone, I just flashed a new BIOS and stumbled upon some features I’ve never seen before. If anyone’s familiar with them, could you help me out? I'm seeing things like CPU CLOCK bias, CPU margin enhancement, and NB CLOCK bias...

EDIT: I did a little digging on the bias settings, and it looks like that's just the Phase-Locked Loop voltage. But as for this CPU Margin stuff... I'm coming up totally empty-handed.

No, it’s not the Phase-Locked Loop, I’m just guessing here😁 I had this CPU hitting 4GHz before, but now I can’t even get it to 3.8.

And just to be clear, it’s a Core 2 Duo on a Z77 Motherboard

I have a question regarding an old EliteGroup 775 socket motherboard I've been messing around with. I previously tried installing an Intel Core i7 on it—well, more accurately, I messed up the orientation and fried the chip. Now I'm wondering how I can verify if the motherboard is actually still functional. Specifically, I want to know if there's any way to test it before I drop a new CPU in, just to make sure I don't end up burning through another processor. Is there any realistic chance this board survived the mishap? I didn't seat the CPU correctly and ended up shorting it out... any advice would be appreciated.

Alright folks, I have a question regarding my x1650pro—I can't seem to push the overclock even by a single clock cycle without the image immediately turning into a blurry mess. Given that the clock speed is already quite high, is it possible that this specific card comes pre-set at its maximum factory clock? Or am I looking at some kind of built-in protection mechanism preventing further scaling?

Arthur Martin9 said:Hey guys, I have a question about my X1650Pro. It won't let me overclock even by a single clock cycle—as soon as I try, the image gets all distorted. Is it possible that mine just comes with the maximum clock speeds pre-set from the factory, or is there some kind of built-in protection?

I'm running into the exact same issue. Neither the GPU nor the memory will budge. Anything I try to increase (or even decrease, actually) just results in a black screen on my monitor... I've asked around on a few different forums, but nobody seems to know why. I've pretty much given up and am just sticking to the stock clocks it came with. I doubt you'll get much help from people here.

Honestly, I’m leaning toward the idea that the card was already clocked that high right out of the box—it's the only thing that actually makes sense to me here.

Hey, so I’ve got a Pentium 4 running at 3.0 GHz and I’m looking to bump it up to 3.2... any idea how one goes about doing that? Also, I'm rocking an NVIDIA 8600 GT with 512MB of DDR3—I guess you could say I'm wondering if overclocking that is even a possibility.

You'd bump the FSB from 200 up to 214 MHz—maybe.

So, how exactly does one go about doing that?

U BIOS settings.

Found it... ran the test with OCCT and it hit 3218.. looks like we're good to go.. heh, I honestly thought this was going to be three times more complicated than it actually was..

Can someone give me a quick rundown on how to overclock an e8400 to 3.6 GHz via the BIOS? Once I've done that, what software should I use for testing, and for how long? Is it bad to let it run under load for extended periods? Also, which program is best for monitoring temperatures?
2x kingmax 800Mhz
e8400
ASUS P5B, s775, Intel P45 + ICH10, FSB 1600OC

Holy cow!

thanks

So I became a member here but I just realized this thread already exists. Let me rephrase my question: why on earth is my RAM running at such a pathetic 339MHz??

I’ve got a Q6600 overclocked to 3.05GHz and I'm rocking 3GB of RAM (basically 2x 512MB & 2x 1GB sticks). Could that be the issue? My motherboard is an ASUS P5B.
When I was overclocking the CPU, I had to dial back those memory multipliers—whatever they're actually called—otherwise the damn thing wouldn't even boot with the CPU OC. Even though the BIOS claims the RAM frequency is 680MHz.
Thanks

DDR2... basically just 339 x 2

Kyle Sanchez4 said:DDR2... you're looking at 339 x 2

Wait, what the hell is that even supposed to mean?

There’s such a thing as real frequency, and then there’s effective frequency.

Your actual clock is 339MHz, which means you're looking at an effective speed of 680MHz.

Thanks. I actually went back and dug through the overclocking tutorials on this forum, which cleared everything up for me. Much appreciated.
