My Setup:

I have 3 GB of RAM:

Two Kingston 512 MB Ram (KVR800D2N5/512)

This is what I want to OC: Dual Core E8600 3.3GHZ (still need to purchase)

Would this work? Any hardware incompatibilities? Do I need to change any options to OC safely?


Thanks in advance!

Not sure if this makes any difference, I also have the following:

Crucial M4 64GB SSD I plan on purchasing as primary OS (XP)

I also have an artic cooler freezer pro 7
 
Solution
I would remove the two sticks of 512MB RAM; having all four DIMMs populated will make your OC much more difficult. I would also look for a 500W 80+ Bronze or better PSU, assuming you will add a discrete graphics card. The Arctic Freezer Pro will work fine.

As soon as you have your system set up, run memtest86+ on your system's stock settings, one stick at a time, and if both pass, then again together. Let memtest run until it has successfully completed a complete cycle. Any errors and you have bad RAM - RMA for replacement - if you cannot RAM it, buy a new set of RAM, and repeat the memtest86 tests.

After you are sure the system works at stock, run some stress tests like Prime95 and OCCT to ensure the system is stable at stock. Once...

After you are sure the system works at stock, run some stress tests like Prime95 and OCCT to ensure the system is stable at stock. Once you have that, you can change some BIOS settings for OC. Disable all the CPU options in the BIOS except hyperthreading and increase the CPU voltage to 1.3V

Then get a pencil and paper to write the down the other BIOS settings you change and the results. You want your OC to POST, boot to the OS, and run stable under stress. If you are really, really lucky you'll start with a 400FSB with the RAM divider setting your RAM at its rated settings and achieve a stable OC. But every board and CPU are a little different, so it is likely you will spend a great deal of time through trial and error finding the highest FSB that your system will run stable.

Hey thanks that is a useful guide.

I have a very light setup (Nvidia GeForce 7600GS) and ran the PSU calculator and recommended wattage was about 270W without OC (Stock 3.33GHz 1.2 VCore) and with OCing (4.00Ghz 1.2 VCore) it only increases slightly to 277W. I think I saw a newegg review who said they didn't have to change Vcore and OC'd it at 4Ghz.

Also to be safe I changed it to 4.00Ghz 1.33 Vcore and it increased to 298W/248W. (Recommended PSU wattage/Minimum PSU)
(http://extreme.outervision.com/PSUEngine)

Should this be okay with my 380W? if not I can still invest in a better PSU but would like to save money if I can.

I am more concerned about RAM sticks, can I leave 3? (Either three 1GB's or two 1GB's and one 512MB)


-----------------------------------------------------------------------------------------------

Btw I have never OC'd before and was wondering- If I followed your instructions to the T and maybe did a little more HW, how safe is it? Over time, does it put any significant risk of damage to my motherboard or any other components or is it just my CPU? Are my hard drives and data at risk?
 

See above. Look at my configuration. I've had my E8600 stable at ~4.2GHz, but I cannot find the CPU vaildator link right now.

I highly recommend keeping a log of the settings you make to your BIOS and the results: POST, boot to the OS, and stable. Using a log will show the FSB/RAM divider you already tried, so you won't try the "Fails" again.

This didn't copy as well I had hoped from the excel log, but you get the idea. The "1" indicates success and "0" is FAIL. When I got to the OS and ran Prime95 and OCCT, the system was stable.

 
Removing RAM:
No. You're wrong. Leave the 3GB of RAM in there. You can run MEMTEST easily enough to ensure your RAM is working properly.

Also, RAM is installed in pairs usually unless you only have one stick. Again, run MEMTEST and leave it if things are fine.

Overclocking CPU:
You need to invest in a CPU heatsink. Spend roughly $40. Need to spend a little time reading comments. NCIX is a good place to start.

Power Supply:
You haven't mentioned your graphics card unless you're just keeping the current one. That's the most important part in deciding on a PSU.

???
It's hard to help if I don't know what you're attempting to accomplish. You don't want to invest too much in an older system. There's no point in getting a new CPU, PSU and graphics card to upgrade this as a gaming PC for example. At that point it's best to build a new system as that would run you $500 or so.

Anyway, if you give me more details I can help better.

Did your current CPU die? Why are you getting a faster one? (because for games your graphics card is the bottleneck)
 
RAM update:
If you have a 1GB graphics card, you can probably access about 2.5GB of RAM but it's still best to keep all 3GB if possible.

(32-bit Windows can "see" 4GB of total memory which also includes the VRAM on your graphics card. If you had a 1024MB graphics card you would might be able to access 2.5GB of System RAM, but with a 512MB you might get 3GB)

Hey thanks for the log, its a great idea.

I still have to purchase and wait for my E8600 to arrive, but I think I might just test out my E2180 right now just to see how much real time difference it makes.

Hi photonboy,

I have a Nvidia Geforce GS7600 512MB.

I am getting a new CPU to increase speed on my computer. I want to get as much out of this system before I invest into a brand new machine.

so I should also get a heatsink on top of my arctic cooler freezer pro? Is it not enough by itself? I also have a "cooler master" case.

And I can keep 4 sticks of ram, as long as MEMTEST passes? And only to remove some if it fails? Worst case scenario, I can always just go with two sticks? (2GB/2GB or 1GB/2GB vs 1GB/1GB)
 
You're welcome. Have some fun with it.
