Overclocking Noob Here

post #1 of 17
Thread Starter 
I just built a new pc and figured I would start learning how to overclock. I have the following main components installed:

Dual-Core 5000+ BE processor
ASUS M3A78-EMH HDMI motherboard
G-Skill 2gb(2 x 1gb) 240-pin DDR2 800(PC2 6400) dual channel kit memory

I have been following Durch's overclocking guide, but I'm starting to wonder if I really need to do quite that much work. Because the cpu has the unlocked multiplier, do I really even need to mess with the reference clock speed? From everything I have read, the 5000+ pretty much maxes out at 3.3ghz. This appears to be easily achievable with a 16.5x multiplier and 1.45 voltage. I'm certain there must be more to it, but I'm not sure. Is there some other benefit to increasing the reference clock?

I'm also a little confused about the memory. If I overclock the cpu to 3.3ghz, then the memory speed drops to 733. What effect does that have on performance? Am I better off with the cpu at 3.2ghz, which makes the memory speed 800?

Thanks in advance for the assistance.

Rbeal, it's always nice to know what your chipset is capable of so yes I would recommend playing with it. The best way to find out whether or not your processor is capable of a certain OC is to just try it! Nothing is ever guaranteed in overclocking.
To be honest I would choose processor speed over memory frequency speed. When it comes to AMD processors, clock speed is the king.

Let us know how far you can take it.

Good luck

Hey rbeal74,

Welcome to OCN! It's easier for us to help you if you fill out your system specs. Once you do that, it will appear in your signature below each and every post you make. You can fill them out by clicking here.

You're right, the X2 5000BE is nice in that it has an unlocked CPU multiplier, so you can overclock the CPU (and only the CPU) simply by increasing the CPU multiplier. Remember, this will never overclock the memory, and will actually underclock it slightly if you choose a CPU multiplier that is not an even whole number (like 10, 12, 14, etc). All half and odd CPU multipliers underclock the memory.

However, with AMD X2's, CPU speed is king. Memory overclocking can provide small performance boosts, but nothing very noticeable. So here's what I recommend for 5000BE users: Set the CPU voltage at 1.500v and the CPU multiplier to 16, and increase the reference clock from there. See how far the CPU can go first, so underclock the RAM by setting it to DDR2 533 or 667, loosen the timings to 5-5-5-15-24-2T, and give the memory the recommended voltage (depends on your memory, look it up on the manufacturer's web site). Once the CPU speed is at its highest stable setting (can pass a 24-hour Orthos small FFT test), then leave the timings at 5-5-5-15-24-2T and raise the memory to DDR2 800. If that works (and it should) start tightening the timings. See if it's stable at 4-4-4-12-24-2T. If not, then reset it to 5-5-5-15-24-2T and tighten the timings one at a time. You'll probably get somewhere between 3.2-3.3GHz, but as thlnk3r said, nothing is guaranteed.

It looks like I can only increase the cpu voltage in my BIOS to a maximum of 1.4v, so I guess that limits me somewhat. The other bad news is that I blue screened at 1.4v and 16x multiplier. That was with the reference clock at 200mhz, anf the memory timings at 5-5-5-15-24-2T. I can't believe the best I can get is 3.1GHz out of this thing. Any suggestions?

Rbeal, actually that is a pretty good overclock. You went from 2.6Ghz to 3.1Ghz on 1.4volts...in my opinion that is awesome

Have you had a chance to do any stability tests yet? I recommend running Orthos with the blend test at priority 9 for at least 5-6hrs. Keep your eyes on your temps because they will rise during the first few mins of your stress testing.
If you want, post up CPU-Z screenshots of your 3.1Ghz OC and perhaps maybe we can assist you on pushing that processor farther.

Good luck

I actually put the voltage back down to 1.35v with a 15.5x multipier. So far I ran that thru an Orthos blend test at priority 1 for 30 minutes with no errors or warnings. Max temp was 46 degrees. I'm switching it over to priority 9 now to let it run for a few hours. I would be more than happy to post my CPU-Z screens but I can't figure out how to do that! LOL...what a noob I am.

Rbeal, I usually take screenshots of each tab using the "PrtScr" button and pasting them into MSPAINT.exe. I cut and crop the images and then save them as .jpg's. You can upload the images to photobucket or if you have your own FTP space you could save them there too. After that just click the "Insert Image" button and type in the URL to the picture.

Hope that helps

Orthos has been running for almost 5 hours now with no errors. The temp has been holding steady at 46 degrees. I'm not sure if that is good or not. Where should I go from here, since it would appear raising the multiplier any further, even while increasing the voltage, makes me unstable. Here are the CPU-Z screens:

Rbeal, excellent OC for 1.35volts

Let us know when your Orthos stable and perhaps you could try for 3.2Ghz

Good luck

I ran stable on the previous settings for 12 hours on Orthos. As soon as I increased my multiplier to 16.0(3.2ghz) at 1.35v, I started blue screening. I increased to 1.375v, but still blue screened. I then increased to 1.40v and actually got logged into Windows. I started my Orthos test, but blue screened before it ran 2 minutes. It would appear my multiplier threshold is 15.5x, so I'm not sure if I'm done at this point then or not. Should I start trying to increase the reference clock now?
