So I have the AMD Athalon 3800+ x2 Dual core processor. And I just ordered the Thermalright Ultra-120 Extreme with a 120mm fan. And was wondering how far do you think I will be able to OC my CPU..

Also do you have a good OC guide that I can use as reference? I'm looking for something detailed..

Heres my specs if they matter :)

AMD 3800+ X2 Dual core with Thermalright Ultra-120 Extreme
700wat PSU
2gig DDR400
8800GTS Superclocked
 
anywhere between 2.4-3.2ghz depending if the computer gods love you.

In other words, it really depends on your cpu. Mine sucked and only went up to 2.4ghz. My friends was the god of gods. It clocked 2.8ghz on stock volts and can easily do 3.2ghz.

what do you think the chances are that the computer gods are generous?

And do you know a good OC guide by chance?
 
ok, let me rephrase this again.

A cpu is not the exact same as another cpu. One may overclock higher w/ lower voltages. It really depends on the cpu. The average clocks people achieve is anywhere between 2.4-2.6ghz. If you get 2.7-2.9ghz then your cpu is already concidered quite good. My friend lucked out and got a very nice ocer.

Other issues you may run into though, may be a fsb wall on your motherboard. If it can't do say over 250fsb, then the highest you will get is 250 x 9 = 2250mhz. Your ram may also be an issue and can not go over 250mhz, so you use dividers, to run your ram slower than your cpu. This way, your cpu may be at 2.8ghz, but your ram still runs at stock.

There are stickies around and such to help you with overclocking.

Few things when overclocking:

Set pci-e speed to 100mhz. NEVER CHANGE THIS.
Set HT multiplier to 4x or 3x before overclocking.
 
thanks, guess i have to wait until my Heatsink gets here to do it.

How will i be able to tell if the OC speed is stable or not?
 
I didn't put this is my OP, but I have the DFI LANPARTY UT nF4 SLI-DR Expert motherboard if that makes a diff in the OC process.

yeah, that is argueably the best mobo for skt 939. At least you don't have to worry about the mobo.
 
thanks again for your help. Ill post back here with my results when i get my heatsink.
 
im sittin at 2585 right now, which is OC'ed roughly 585mhz. The computer gods dont smile upon me, one click higher on the clock spd and the system just isn't stable for me. I'm happy with the current clock though I am eagerly awaiting some new am2/am2+/am3 chipsets to come out so I can upgrade :D
 
What settings are you using? Have you used the ram divider? It sounds more like you have reached the ram's limit and not the cpu.
 
So I just bought the Thermalright Ultra-120 Extreme CPU Cooler and I wanted to OC my old 3800+ X2 Dual core to get the most out of it before i have to upgrade.

SO I get it today, and following this guide

1. Boot the computer into the BIOS screen.

2. Increase Motherboard Clock Speed or FSB speed in 5-10MHz increments. Reboot after each increment to ensure that the system can still boot into Windows properly.

3. If the system hangs, crashes or refuses to boot into Windows, increase the memory voltage slightly and retry. If this does not work, increase the chipset voltage slightly and try again, finally, increase the core voltage. If this still does not work, reduce FSB settings slightly, reset the voltages to their previous values and try again.

4. Keep going until the computer can no longer boot reliably into Windows, then back off to the previous safe settings. Keep an eye on the processor's temperature in the BIOS. Remember that it should be under 70°C to avoid limiting the overclocking potential and triggering the processor's thermal throttling feature.

5. Benchmark the overclocked system and compare the results to the performance baseline established earlier. If the system does not complete the benchmarks or crashes, either reduce the FSB setting slightly or increase voltages to compensate and retry.

6. Depending on the current overclocked FSB speed, a memory divider may be used to try to achieve higher speeds. Note that the memory may not be the limiting factor, and if it is not, the divider will not help.

7. Once a fully benchmarked overclocked setting is achieved, run the Prime95 stress test for a couple of hours to verify that the system is generally stable. Enjoy the free additional performance!

from here http://www.pcstats.com/articleview.cfm?articleid=1804&page=1

And I followed the steps. Increased my FBS Bus Frequency bye 10 each time.

So started at 200, went to 210, then 220, then 230. At 230 it seemed like some programs had a hard time starting up. And they went to the "Not responding" window.

So I restarted the comp went into bios, and increased my DRam Voltage to the next available voltage (think it was 2.66? maybe dont hold me to that)

Started it up, seemed to do it again. And following the guide I upped the Chip Set Volt next.

Then it started up and is working fine. So I am at 2.3GHz right now

Now i try to go up to 240MHz and I get this weird windows screen telling me to instert my windows cds..

So i tried what the above said, I increased my Memory, then Chipset then Core volt and it still did it.

Does this mean that the furtest I can go is 2.3 GHz? If so that kinda sucks........


Also I was a lil confused by which volt to increase since mine didn't say Memeory volt, or Core Volt.

I have

CDT Volt control (I assumed this was the core volt)
and the
DRam Volt control (assumed it was the memory volt)


Any help would be great!!!!!!!! thanks

The God of Gods is currently an F3 3800+ stepping CCB8F 0715 MPMW.
It does 3.6 on at 1.6V
That's something.
That's insane. I'm guessing thats just stable enough for a screenshot and nothing else though.

My 3800 is wierd, it will do 2500Mhz with stock volts, but regardless of volts will not move past this. With 1.6v I can get to 2550Mhz but it's not worth it. :(

Clendest.

Your board might not have a Good PCI lock and is making your hardrive go funny.
I have the DFI LANPARTY UT nF4 SLI-DR Expert
 
That's not mine unfortunately I also have an F3 but this won't even do 3.3 stable. sigh.
A guy on xtremesystems and did superpi at 3.55G unlikely that's stable either but 3.4 wouldn't be bad from a 70$ chip. ;)

This seems to be the SOI problem, I can do 3G at 1.325 but then have to feed it really bad to move up 1.475 for 3.2. :bang head
