Overclocking (Main Thread)

It’s pretty obvious you don't really get how hardware works.

Sam Edwards5 said:so I just turned on the cooler and added another core and another heatsink from an old P4 at 1.7 so I bumped the clock up to 266, and I disabled the temperature control in the BIOS so the system shuts down if the CPU starts acting crazy.

I honestly didn't understand a single word of that. Maybe try using some punctuation.

I think the temperature is fine; you might want to change the thermal paste, but it isn't cause for concern.

Hey everyone. So I've run into a bit of a snag here😛I'm running a Core 2 Duo E6750 on an ASUS P5KPL motherboard—everything seems totally fine and runs smooth under normal loads, but whenever I try to push the overclock past 2.72GHz—say, up to 2.93GHz—it holds steady even under full load, but my internet connection just goes completely haywire.
Anyone have any ideas what might be causing this?

Are you sure the internet connection is actually tied to the overclock? That shouldn't really be an issue unless we're talking about general system instability or something similar.
And what specifically isn't working? Is the browser failing to launch, or is it just refusing to connect?

So, here’s the deal: back in the day, whenever I tried overclocking, my MSN Messenger would just totally freak out and stop working—even if Internet Explorer would pull up whatever I was searching for, trying to load specific sites would just fail. But the second I dialed things back down to 2.66 or 2.72 GHz, everything would snap right back to normal. It happened a hundred times, honestly. Now, I’ve run into a whole new headache that’s kind of related—I just updated the BIOS, and now my MSN won't work at all. To make matters worse, my idiot brother actually reached in and popped the CMOS battery out of the motherboard while the PC was still open... could that be part of the problem?
THANKS

I think you might be conflating hardware issues with software ones. If the system isn't crashing—or if specific apps aren't failing when they demand more CPU power than just basic browsing—then overclocking probably isn't your culprit. Pulling the battery just reset the BIOS to its factory defaults.

Alright, finally sorted out that BIOS headache—I've been digging through my PC all day trying to play hero and fix it, but turns out the clock was just totally off. Had to sync everything up and get the date and time set correctly 🙄😁. Now, about this overclocking issue... does anyone actually know how to tackle this? It’s clearly tied to the clock speed because once I push past 2.72 GHz, the internet just dies, even though everything else seems fine 😕

What’s the ceiling for overclocking a Celeron 2.53 GHz—133 MHz FSB, 19 multiplier? The rest of the build is an ASRock board, 2 GB of RAM, and an AMD Radeon HD 3600.

It's not worth the effort... you won't gain anything from it.

If the stock speed is 2.53 GHz and I overclock it to, say, 2.7 GHz—doesn't that technically mean the CPU has more power, potentially letting demanding games run without stuttering?

That basically means your processor is pulling an extra 170 million cycles per second. It sounds like a massive jump when you put it that way, but we’re really just talking about 0.17 GHz. I don't think that translates to being able to run much more demanding games. If your CPU is already hitting the bare minimum requirements for a title, it might launch, but the performance will probably still be pretty questionable. You'd likely see maybe a 2% boost in performance—which isn't much at all—meaning if you're getting 20 fps, you might bump up to 21. If the game is stuttering now, even overclocking it to 3.5 GHz probably won't fix the lag.

A Celeron is weak by design... you won't even notice a difference

On Intel chipsets, memory speed scales automatically right along with the FSB. You get those different ratios—like that 1:1 symmetric setup where a 266 FSB on a Q6600 defaults to 532MHz for the RAM. But here’s the real headache: when you start pushing high FSB speeds, like running an E8500 at 500x9.5 to hit 4500MHz, the minimum memory frequency jumps to 1000MHz. Not every piece of DDR2 out there can actually handle that. It gets even worse if you've filled up every single memory slot on the board; trying to overclock the RAM—or deal with the strain on the CPU itself—becomes a total nightmare.

I’ve got this 1GB Kingmax stick running at 1020MHz with 2.2V.
I’ve got 2x1GB Kingmax sticks running at 960MHz with 2.2V.
I’ve got 4x1GB Kingmax sticks running at 850MHz with 2.2V.

So, what's your question?
The maximum frequency depends on the memory chips, the motherboard, cooling, the power supply, and plenty of other variables.

I've got an ATI Radeon 9200 SE Omega 3.8 with 256 MB

Is there any way I can boost its performance just by using some kind of software?

Yeah, that's what we call overclocking xD
Anyway, do you even realize how old this card is? You aren't going to get anything out of it, except maybe a 5% bump in performance on ancient games. It's a weak card, honestly kind of a meme at this point—just an outdated GPU running Shader 1.4. It's a no-go.

hm... I wonder how much a decent graphics card would run if I were buying it brand new today?

Hey, I’ve got a quick question for you guys...
So, here’s my current setup: I’m running an ASUS P7P55D motherboard with an Intel i5 750 clocked at 2.66GHz. For memory, I’ve got 4GB of Corsair DDR3 at 1333MHz. My GPU is an EVGA GTX 260, and I'm pulling power from a Fortron 500W unit..
I'm just using the stock cooler on the CPU right now. As for the case, it's a Thermaltake Armor+ full tower—plenty of room in there and the airflow is absolutely killer..
What kind of speeds can I realistically squeeze out of this? I know my current power supply is a bit of a weak link, so I'm already planning to swap it out for a Corsair 650W very soon..
While I was messing around in the BIOS, I noticed the board has this built-in overclocking utility. It basically does the same thing we do manually—cranking up the frequencies and voltages, then resetting to see if it actually boots. I managed to hit 3.21GHz, but the catch was that it throttled my RAM speed down..
So, here's the big question: could I push it even higher if I did everything manually?
Also, I'm a little worried about the CPU temps. I'm thinking about picking up an aftermarket cooler, but I'm totally lost—any recommendations on which one would be best?

Anyone out there??

- the power supply is more than enough even if you decide to go for some serious overclocking
- honestly, nobody can tell you exactly how far you can push it without some real risk
- just forget about trying to overclock via software... it won't work
- and don't even think about touching this without a better cooler (the Katana is fine if you're staying within the range of$67)
- but first things first, go read a proper guide on overclocking; there's one right here on this forum
