Ok i've currently clocked my pc to 4.2ghz on my core 2 duo e8500 using 433x9.5 and jacked my vcore to 1.36 problem is while im booting into windows its really slow for some reason.. takes time to load programs and stuff.

It also says i have 1 Core? lol here is screenshot..

That's.... odd.

Remember that your FSB is also tied to your Northbridge. This may cause errors. Go to CPUID and download PerfMon. Check for things like "L1 Data Cache Success Rate" and the same with anything else that says "Success rate". (You may do so by clicking one of the four graphs and choosing from the list that pops up.)

I'm not familiar with Intel boards, but down near the bottom, it should say something about "something-something bandwidth". That will hopefully not be maxed out when you stress your system (example, a game or a benchmark/stress-test utility).

If you're still having problems, try making your own thread not many people will see your post here.

Current Information?

Hi, I came across this post and would like to know if it is still considered current, and if not where I might find a more up to date guide.

Thank you

It's more of a "generic" guide that helps you understand more of what's actually happening inside your computers. A Phenom will clock up differently than a Core 2. An nVidia chipset will be more or less finicky than an AMD or Intel chipset, etc. This guide is more of a starting point.

Good luck!

Surely the forums can still be used for guides? If people are looking for overclocking guides they'll probably come to the Overclocking and Cooling forum first. I can see where you're coming from, but I think if it's going to work like that all the guides that have been stickied should be moved to the Wiki and then unstickied so everything is in one place, rather than being dotted around. I don't mind copying a few of the guides into the Wiki sometime.
can you please help me over clock my machine....I am stuck at the FSB part...new at overclocking and new to the forms.the fsb is at 200 mhz..Check out my configuration on my machine.Thanks =)

:laugh: I never said it was unbiased. :p

I'm not much of an Intel person, but I'm guessing Intel's "QuadPumped FSB" works the same as HT, correct? How do the Core 2 Duo's do it? I heard nVidia's Intel chipsets use HyperTransport.


Edit: The guide has been de-biased. I just didn't feel like writing the Intel section when I wrote it. It's a work in progress, right?
You're not much of an Intel person, still you have an Intel laptop now, time changes eh? :p Ontopic: this is a useful guide to my older computers which now are retro...

The original post started out as a reply to a question in another thread (which definitely contributed to its less-than-neutral wording) and grew to the point where I thought it would do better on its own. Rizzo was very correct to point out that a guide like this should be unbiased especially considering there was talk of it being stickied.

The times do indeed change. Back in 2007, I chose AMD because I was concerned about price/performance with an emphasis on price. These days, my finances, priorities, and undeniably maturity sit somewhere closer to where I'm more concerned with what-can-I-cram-in-a-laptop/performance and power bill/performance. The beauty of both manufacturers is in the variety these two giants provide so that we, the consumers, have the power of choice. Something I was admittedly more blind to originally.


It appears this is going to end up being a brief addendum to the original post since I keep tacking on more and more outside the topic of the recent messages.
Looking over this guide, a lot of it still seems to apply, just a bit of the terminology has changed. I'm less in touch with the world of overclocking these days, but looking at modern architecture should provide some insights. I'll compare to my Team Blue CPU, the Intel i7-6700K, and reference this nice article on wikichip.org which documents the Skylake architecture and lists what they're referring to as clock domains.

FSB can basically be interchanged with BCLK, something true at the time of writing for the original article as well. This is, as I understand it, still used as a primary clock reference for many sub-systems (memory, PCI-E clock, etc).
CPU speed, referenced above, is commonly referred to as core clock or core speed and is the main spec of a processor.
Intel's QPI and AMD's HyperTransport can be interchanged with Ring for modern Intels and, apparently, Infinity Fabric on modern AMDs. This provides the heavy lifting of internal data transfers between your PC's main components (CPU to PCIe bus, for example).
Memory clock speed hasn't changed much at all, although the formulas for the ratings have. In the scope of overclocking, I wouldn't recommend worrying about much other than the speed in MHz since memory ratings change between physical generations and (generally) cannot be swapped out.

The primary purpose of this guide was to answer some of the basic questions of overclocking and provoke new questions deeper into the field. I was and still am thrilled to see it has helped. Happy tweaking!
