Overclocking (Main Thread)

So, I did a quick search on Google for an NVIDIA Control Panel download, scrolled through some sites until I hit Softpedia, and grabbed the installer from there. But here’s the kicker—the moment I tried to run it, these massive blue squares just popped up right in the middle of my screen, and then the whole system just gave up and rebooted on me. For context, I'm running Windows Vista Business on this machine.

I'm running into the same headache
using an Intel Core 2 Duo E5400
I’ve got the FSB at 242MHz and the multiplier set to 11, which puts me right at 2.66GHz
Voltage is sitting at 1.4V on the CPU, and I bumped the memory voltage by about 0.2V
Everything seems stable enough...
But the second I try to push it even a little bit further, the whole system fails to boot
The board I'm using is an ASUS P35 series
Does anyone know the ideal settings to actually hit 3.2GHz without it crashing?........
Honestly, I can't quite wrap my head around this BIOS interface

iiiii

1.4V is overkill...

I'm running mine at 11 x 273 / 3GHz/ with 1.35V... what kind of RAM are you using and what's your clock speed?

Kyle Sanchez4 said:yeah...

1.4V sounds way too high for me...

I run mine at 11 x 273 /3GHz/ with 1.35V... what kind of RAM are you using and what speeds are you pushing?

Maybe I'll drop the voltage a bit and set it up the way you suggested...
The memory is some old Kingmax 2GB 800MHz stick...
Right now it's sitting at 807, CPU-Z shows 403.4—I guess that's it then—and the latencies seem low too, which I don't really get... Do I actually need to tweak those settings...
Gonna mess around with it for a while longer...

you don't even need to touch the memory voltage

No luck😠
In the advanced BIOS settings, I go ahead and disable all that useless junk—C1E, EIST, all of it...
I also tweak the PC health settings following some tutorial I found online.
I set the frequency to 255 and leave the multiplier at 11... which puts me right at 2.8 GHz total.
Managed to get the memory running at about 820...
I haven't touched the latencies because, honestly, I don't have a clue what I'm doing there...
I just bumped the CPU voltage up to 1.35...
Windows boots up fine, but as soon as I fire up Orthofix, the whole system just restarts after a few seconds...
What else is left to tweak? I'm starting to lose my patience here...🙄

Not all processors perform the same way... mine won't push past 3.4GHz... (the e4500 does too)

Mine won't budge past 2.7 🙂
maybe I just don't know 😵

Hey everyone, I have a bit of a puzzle here... I’m running into some persistent issues with overclocking my E5200. It’s a strange one—when I bump the clock speed up slightly, say anything north of 2900 MHz, everything runs smooth as silk, even pushing toward 3.5 GHz. But there's a catch: if I shut down the PC and leave it sitting for a while, things go sideways upon reboot. When I power it back up, the BIOS starts to load, but then the system just restarts itself about 5 seconds in. Then it tries again, only to crash after 2 seconds, and a third time it restarts after 3 seconds. After those failed attempts, it finally boots into the BIOS and Windows normally, but it completely wipes my OC settings and reverts back to the stock 2.5 GHz. Does anyone have an idea what might be causing this loop? Any advice on how to fix it?
My setup consists of a Gigabyte EP35-DS3 motherboard, 2x2GB of Corsair 800MHz RAM, a 400W power supply, and an AC-Freezer 7 cooler. I never push the memory past 900MHz, and I've bumped the CPU voltage up to 1.385V—I honestly don't dare go any higher than that...

So, what exactly is the power supply unit here?

The power supply is a Smartbox unit... honestly, it’s pretty bottom-tier. Do you think that might be where the issue lies?

velvetfalcon48 said:The power supply is just some cheap Smartbox junk... absolute garbage. You really think that's where the issue lies?

What GPU are you running?

Anthony Scott93 said:What kind of GPU are we talking about here?

The card is an AMD Radeon 2600XT with 256MB of DDR4—it doesn't require any extra power connectors from the PSU.

casualgull13 said:I'm running a Q6600 on an ASUS P5K motherboard. When I try to overclock it past 280, it becomes unstable, though it stays perfectly steady at 279 (I ran a CPU stability test for about 6 or 7 hours)
What settings should I bump up to get more performance? I've already followed several guides on various forums and disabled those... what are they called? 🤣
I'm running into the exact same issue with an E7200 on this same board..
The rest of my setup is: a Gecube 4870, a Corsair 750W PSU, and 8GB of RAM (4x 2GB @ 667 MHz)

Try adjusting either the CPU multiplier or the memory divider.

I’m honestly not sure if tweaking the multiplier to 12.5 is worth the headache—it would force me to crank up the FSB way too high. As for the divider, I’ve already cycled through 3.33 and 3.2, and it feels like anything else is just hitting a wall; they either end up being far too large or just too small—I don't want to drop below 800 MHz, but there's really no point going over 900.

The real kicker is this OC issue that only pops up after the PC has been powered down for a while—it’s almost as if the system "cools off" too much and then refuses to boot using my current settings...
I actually tried bumping it up to 1.5V just to see if it would cause any instability, but surprisingly, it was perfectly stable and booted up without a single hitch every time... though, I’m pretty hesitant about leaving it at anything higher than 1.37V.

As for the dividers, I've messed around with 3.33 and 3.2, but nothing else seems to hit the sweet spot; they're either too high or too low (I don't want it running under 800 MHz, but I don't need more than 900)

The thing is, this OC issue only pops up after the PC has been off for a while—it's like once the system "cools down," it refuses to boot with these settings...
I tried bumping it up to 1.5V just to see if that would mess things up, but it was perfectly stable and booted without any issues every single time... though I'm terrified of leaving it at anything higher than 1.37V.

Look. Go ahead and drop the multiplier. This motherboard is a beast for overclocking and won't give you any trouble. Set the memory to 667 and then push it as far as it will go (by the way, Corsair is generally great for OC). My suggestion: set the CPU to 11, memory to 667, and start bumping the FSB while staying at default voltage. Once it starts acting up, increase the voltage. Personally, I wouldn't push past 1.4V.

I'm running an E4500 on a P35-DS3R board.
The RAM is Kingmax 2GB @ 800MHz.
I managed to push the CPU up to 2.9GHz using these settings:
FSB at 363 with an 8x multiplier.
Memory is clocked at 871MHz, and the multiplier is sitting at 2.40.
I set the latencies to 5-5-5-15... though I don't really grasp how latency works.
I’m trying to bump it up to 3 or 3.2GHz, but I'm hitting a wall... I've got an Arctic Freezer 7 and I even resurfaced the base, so thermals shouldn't be the issue.
I also can't figure out why it crashes in Orthus when I try 264 x 11... memory hits 845MHz then.
I tried the same configuration with 333 x 9 to hit 3GHz... but Windows won't even boot.
Then I tried a lower multiplier, 375 x 8 for 3GHz... memory is at 750MHz. Windows boots, but it fails in Orthus... and MemTest too.
Can anyone help me dial this in? I just want to squeeze a bit more out of it... the goal is a stable 3.2GHz.

I want to push it to 3 or 3.2GHz, but I just can't make it happen. I have an Arctic Freezer 7 and I even polished the base, so heat shouldn't be an issue.
It’s also unclear to me why it crashes in Orthus when I try 264X11... with the memory at 845MHz.
I tried setting it to 333X9 for 3GHz using the same parameters, but Windows won't boot.
I also tried a lower multiplier at 375X8 for 3GHz... the memory hits 750MHz, and while Windows boots, it crashes during Orthus and MemTest.
Can anyone help me figure out how to tune this so I can squeeze more speed out of it? My goal is stable operation at 3.2GHz.

Have you tried increasing the voltages? If you haven't, then increase them.

clocks the memory at roughly 800MHz..

I bumped the memory voltage up by about .1V
running the Central Processing Unit at 1.375V
I’m keeping the RAM steady around 800, but I just can't seem to push it to 3 without everything falling apart...
