Am I overclocking?
I'm trying to figure this out. I'm much of a NOOB, but I think I understand what's going on. I have an Intel Pentium D Dual Core 930. I think it says it's bus speed is 200MHZ and It's FSB(Front Bus Speed?) is 800MHZ? I dunno. In any-case. This means that I should run my RAM at 200MHZ? I currently set my DRAM Frequency @ 266MHZ though. Am I overclocking? I'm using a Kingston PC2-4200 533MHZ DDR2 1GB RAM stick on one slot KVR533D2/1GR. How can I tell if I'm overclocking. I've run countless tests, but am unsure how to read them. My MOBO is a PCCHIPS P23G V1.0.
 
I'm no expert (so I might be wrong) but I think you're not overclocking, your ram is rated at 553 MHz, since the ram frecuency is 2x that of the northbridge you are running at stock speed, if you run it at 200 MHz you'd be underclocking it (to achieve 1:1 ratio with the CPU).

As for the FSB (front side bus) being 800 MHz that's perfectly normal, the FSB transmit data 4 times per cycle so, if your NB speed is 200 MHz then your FSB speed is 4x that = 800 MHz (about this last thing I'm 100% sure).

Hope it helps. Bye
 
You guys have any idea why, when I set my DRAM Frequency to AUTO it BSODs me? I think I tested anything over 266MHZ and it just BSODs.
Any idea why?

Also (and most importantly) I don't want to overclock and I don't want to underclock. I just want my RAM to run at it's full potential. Can you guys help me configure my RAM to run at it's full potential? I'm not sure if I completely understand the terms and all the information in the BIOS. I learn fast.
 
It sounds like the bios is not properly reading the spd chip on your ram. 266 is 533, the ram is DDR (double data rate) so 266x2=533. Just leave it set at 266 and you'll be fine.
 
up you fsb 5mhz more and test for stability until you get your fsb to 266 stable and DON'T FORGET to get the cpu multiplier down to at least 12x as soon as you get your fsb to 220mhz.

How do I do that? How safe is it to overclock? I hardly EVER turn off my computer and I only have about 3 fans; The one on my power supply, the one next to my MOBO and the one on my CPU.
 
Currently no you're not. Your fsb runs at 800 mhz which is its rated speed and your ram run at it's full potential using a 4:3 ratio.

if you wanna overclock get your ram down at 200mhz and up you fsb 5mhz more and test for stability until you get your fsb to 266 stable and DON'T FORGET to get the cpu multiplier down to at least 12x as soon as you get your fsb to 220mhz or maybe it will be clocked too high. After that overclock your ram will run at it's rated frequency and your cpu will run at 3192mhz over the 3000 rated speed. If it can handle it you could try a 13x multiplier which would make it run at 3458 mhz. don't get past that.

How do I do that?
I want to get it to a 4:3 like you said.
When I Load Optimal Defaults in my BIOS it gives me a 8:5 ratio

Loading "optimal" defaults is never the best idea, as it is not really "optimal" at all. Its more "safe" than optimal, but unless you set stuff manually, you can never have your stuff running at its full potential.
 
ERm, that's a 1:1 ratio. Here's what you need to run at default

CPU multiplier: x15
External clock: 200mhz
Ram at 4:3 ratio

This means your RAM will run at 533 (i.e. double 266), your CPU will run at 3ghz, and your FSB will run at 800.

Set it all manually and you should be fine.
 
I never saw any of this stuff in my BIOS
CPU multiplier: x15
External clock: 200mhz
Ram at 4:3 ratio

How do I set that stuff in my BIOS to achieve what you guys are telling me?

The following link is a complete guide to my hardware including screen-shots of various scans:
http://www.ny-dev.com/My Hardware Guide.zip

Please help me set ALL my BIOS settings.
I'm VERY new to this, so instead of explaining what each BIOS feature is or telling me something like this "Update your bios if you haven't, or if there isn't one. From the parts you listed your cpu should be operating on a 200mhz fsb that's quad pumped up to 800mhz. If your ram is running at 200mhz then your at 1:1. This is what is generally recommended by most users unless you are trying to max all your components.

Also from what I could find on your ram you should be at a CAS Lat of 4 and the others could probably run at 4-4-12/15. Those are my best guesses atm."
I would just really like for someone to tell me what I should set ALL my BIOS settings to based on the Hardware specs/guide I have provided.
 
Just go to the CPU PnP menu. The manual for your motherboard is very poor, and doesnt show the possible selections, so its hard to tell you what to set things to. For DRAM frequency if the options available are like 200/266/333 etc, select 266mhz. If there are ratios in there (1:1 3:4 4:3 etc) then select 4:3. Your RAM speed is set. Forget timings for the moment.
 
With the more complex motherboards and BIOS's available today, system setup whether you want to overclock or not has become more complicated. So has the terminology.

For example, I have an E6600 (266 MHz bus frequency X 9 internal multiplier = 2.4 GHz) running at 3.3 GHz (366 MHz X 9). The BIOS on my motherboard reports the FSB clock as 1467 MHz (366 MHz bus freq. X 4 - quad data rate) and the memory clock as 733 MHz (366 MHz bus frequency X 2 using DDR2 memory).
 
The archive was corrupt. Cant open anything. Do you know how long it takes to tell you what to set every setting to in the BIOS? I spent an hour doing it for one guy and I skipped parts too.

I've re-uploaded the zip. Can you please take a look at it friend?
 
I can now open the html files, but nothing else. Still says its corrupted. Do what I said b4:

This time I have repacked the files, checked them and re-uploaded it. This time it is guaranteed to work.
Once you see my screen shots you will see that it is impossible to do what you said before.
At least that's what I think.
Again I'm a newb, so the best thing would be to just tell me exactly what to do in the BIOS.
 
Ah thats better, now it works. I can see how to do what I said b4 tho. I see the CPU PnP menu option in the main BIOS screen. In that menu there is the DRAM Frequency option. You took a photo of it yourself. Just tell me what options are available under DRAM frequency so I can tell you what to set it at.

Main BIOS screen -> CPU PnP Setup -> DRAM Frequency
 
..., so the best thing would be to just tell me exactly what to do in the BIOS.

Just so you appreciate the complexity of your request, it's roughly the equivalent of asking someone how to tune your car engine for maximum power, via email. Even for a single MB model, BIOSes vary with updates and gain/lose settings, so there's really no good alternative to looking at it in person.
If you want to overclock, you need to be willing to put some effort into learning about your system (or hire someone to do it for you).

The options are 200, 266, 333, 400 and 533 MHZ
 
Well its either 266 or 533. My guess is its 266, as its probably not talking DDR here, so 533 would probably be for DDR2 1066 RAM. Set it at 266, then download CPU-Z if you dont have it (the download link is near the top left). Run cpu-z and go to the "memory" tab. In the "timings" section it should have 266mhz approx for frequency.
