Celeron overclocking (Please Help)

[Jutboy]

Ok, I just did a post 2 days ago and I realize that my comp is not the best at o/c ing.....I wanta give it a go anyway, learn a bit and Id be happy with a 600...firstly I can't find my PLL chip some one said a flat chip next to a shiny one....can someone be more specific.....I have a INTEL 810A which isn't supported by CPUFSB + SoftFSB.....

someone said something about lapping, never heard of this before could some one give me some info....

thanks

[Jutboy]

is there any other progs out there that might work....I notice with these it also o/c's my pci slot........Im currently running a PCI GF2 MX400......could someone give me some info on o/c pci's along with dangers to my g/c

Thanks again

ah, well I found this site -> www.podien.de , which helped my find my PLL, i seem to have two crystals on my mobo...is this possible?...

The one next to my CPU (what I think is my PLL) says:

CY2287PVC-1
A 02 PH1 9935
CYP 625358

the one next to my PCI slots (it is a small little guy)

ND1881
JST
AP69921
-0.3 9932

does that help at all?

[Jutboy]

just remebered another question....I noticed a feature in CPUcool adjusting the L2 cache (1-15) does anyone have any info about this.

I'm a little confused; are you talking about overclocking a Celeron 500 or a Celeron 600? There is a huge difference between the two. Also, "lapping" applies to the Mendocino Celerons. Coppermine Celerons should NOT be lapped.

Lapping refers to sanding flat the heat spreader of the CPU. When I lapped my Mendocino 500's, I sanded them until the nickel plating was removed and the copper body of the heat spreader showed itself. The 500 that I tested with the other day has never been lapped like the other three were. There were at least a couple of articles in the past which indicated that lapping the Mendocino Celerons reduced the CPU temperatures by several degrees. My experiments confirmed this to my satisfaction. Note: Lapping a CPU can ruin it and WILL void any waranty. If you are going to lap a CPU, make sure that you have

that's your PLL.

although i fail to see what finding which one you have is going to tell you. as you said yourself it is not supported by CPUFSB or softFSB.

if your motherboard is an intel branded board (not just the chipset, the whole thing) i wouldn't waste any more time on it. you can't overclock them.


BTW, on the medochino celerons, the part you lap is not a heat spreader. it is the core. if it was a heat spreader it would be far simpler to just remove it, as is done with P4 and tualatin cpu's.

Interesting. I didn't know these cores contained copper.

Don't lap the CPU core unless you want to run the risk of damaging it. However, lapping the heatsink is usually a good thing to help lower temps (but is not necessory until you start pushing the overclocking envelop). Using Arctic Silver thermal paste is highly recommended too. Like was said earlier, if that's an Intel brand mobo, give it up. Intel don't like overclockers, so they only have official FSB settings (like 66, 100, and 133 MHz).

Listen to the man... I would just give up with using programs because even if you do get it to overclock, you're not going to get the best out of it.

I reckon I'll lap this one too and let you know how it turns out.

Looktall:

You are apparently correct in saying that the Mendocino socket Celerons do not have a heat spreader. What the Intel Web says is that it is a nickel plated copper-slug which aids in distributing heat. The danger in lapping the socket Mendocinos is nowhere near as great as with the Coppermine Celerons (which I never did lap and would strongly warn against lapping) in which if you lap, you are sanding the CPU core itself. Sorry that I used the wrong term to describe the top of the package.
