OC ****

[PrOLifIC_onE]

Ok, while I have built a lot of computers, I have avoided OCing, for fear of doing something completely stupid like frying a CPU or MB...

So now I am ready to take babysteps and need your help. I am still using the default bios options for this PC. I bought this OCZ PC4000 ram in hopes of being able to do some OCing. I have been using a standard HSF but I am waiting for the upgrade HSF Arctic Cooling Freezer 64 Pro that One4Yu2C suggested for a cheapskate like me...

For case fans, I have 2 intake and 2 out (obviously not including the PSU).

Anyway, I don't know what might help you but here is the CPU-Z info to start with:








WELL, this version of BIOS that I have only allows for a multiplier change upto 10. And I can not change the bus speed or anything else. I am hoping to upgrade my bios and maybe get more options that way, or else I am probably screwed...

With the exception of the FX processors, all socket 939 A64 processors are multiplier locked, meaning you can't increase it past stock (in your case, it's x10). You can lower it, but let's not focus on there just yet.

To access your CPU fsb options, reference here (LINK), which has pics of your motherboard's BIOS focusing on the overclocking section. In short:

- Go to the Advanced menu
- Go to Jumperfree Configuration
- Change the Overclock Profile to Manual
- Go to the Frequency Configuration submenu
- Inside you should see a setting for CPU Clock, which is your fsb

Also keeping in mind that you'll need to adjust the HT Link Bus (as we discussed via Skype) if going for a modest overclock or higher, you'll need to navigate as follows:

- Go to the Advanced menu
- Select the Chipset menu
- Adjust the LDT Bus Frequency, which is your HT mutliplier

I believe your motherboard lists the LDT Bus Frequency in MHz rather than a multiplier, and if so, it breaks down as follows:

1000MHz = x5 (stock)
800MHz = x4
600MHz = x3
400MHz = x2
200MHz = x1

If you still can't find the necessary options, I could always make a house call on one of your days off.

Probably not reported properly. *shrugs*

It's being misread. There's no way the proc is running a 3.0V, and I had him run CPU Burn In to check his load temps yesterday, which was sitting very comfortably in the mid-high 40s.

[PrOLifIC_onE]

I am at work right now but if I remember correctly, there were 2 voltages listed in bios, one was around 3 and the other around 1.3. I don't remember what they were for or anything like that. But I am sure that is why it is being misread. CPUZ is likely pulling that other voltage reading (whatever it is) instead of the 1.3.

And I looked through the current bios fairly well and there was nothing titled "overclock profile" in the jumperfree configuration. Maybe once I flash the new bios it will be there. Currently is v1002, the latest for this MB is v1010. I have to throw on a floppy drive this week to do that though. I have extras, it's just a matter of finding the time in the next couple days to do it all.

That CPU should be a decent overclocker. Don't expect anything like the C2D's of course, but I wouldn't be surprised if you got another 400Mhz out of it.

[PrOLifIC_onE]

Thanks to One4Yu2c!! I got this baby up 25% to 2500Mhz and stable. I actually ran the CPU Burn-in for about 30 minutes and I saw it get up to 46*C briefly but it stayed stable at 44*C 99% of the time. Room temp = 20*C (about 67*F).

OH And I am still running the original HSF. I'll install the new Arctic Cooler HSF tomorrow and see how it compares.

[One4yu2c]

And he's chugging along on a 1:1 ratio, too. It was basically an effortless push to a 250fsb w/ no CPU voltage adjustment, and those temps on stock cooling are looking great.

Congrats on your first OC, PrOLifiC! Hopefully the next time will go a lot less smooth, giving you a chance to get your hands dirty troubleshooting.

I had enough trouble trying to add the damn floppy drive and almost frying my PC. Then I felt especially happy when I found out that I could flash the bios from the windows desktop and I didn't need to flash it on boot up.

But anyway, all's well that ends well. After the smoke cleared and the dust settled I ended up with this nice overclock and the only thing I fried was cheap chiefmax PSU....
