Overclocking noob. :(

post #1 of 9
Thread Starter 
Hey guys, just joined up on here. Realized when I was going through Google to find information that I've been needing, it's always came from overclock.net. Figured I'd skip the middle man, and go straight to the source, so to speak.

I have a 2.6GHz AMD Sempron 130 OC'd to 3.081GHz with 8 gigs of memory, stock air heat sink, two 500GB hard drives in RAID 0 and 250 watt PSU. I seem to be stuck at 3.08, even though I can boot in at 3.12. It tends to be unstable, and I absolutely can not go any farther than that. The highest temp I see is 43C, and it idles at 32C with 3.12GHz. I've tried pumping up the voltage on the CPU and memory and what not, but it doesn't seem to have any effect on letting me overclock more. Maybe it's my noobishness showing, but I can't seem to break past that. Looks to me, temperature wise, I could go a whole lot more. I assume it's my wimpish PSU, but I have no clue. Any ideas?

Quite often your motherboard will be the limiting factor when trying to OC. That and the chip's ability to be overclocked. If you give us more information about your setup, there's a much greater possibility that we'll be able to help you!

EDIT: Though it seems that your chip IS capable of more than what you're getting out of it, provided it is supported properly by other components.

Thanks, man. I own a hosting company, and this server wasn't being used anymore, thus I claimed it as my new desktop. The motherboard is a BIOSTAR A780L3B AM3 AMD 760G Micro ATX AMD Motherboard, RAM is two 4 gigs sticks of Pareema 4GB 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10600).

Here's a validated CPU-z output:
http://valid.canardpc.com/show_oc.php?id=2313570

Running Windows 7 Home Premium x86, possibly about to dual boot Slackware 13.37 x86.
About to do submersion cooling with mineral oil and a phase change or peltier unit. I know this setup isn't awesome holy crap wow how did you afford that, but it's what I'm dealing with right now. Trying to get the most out of what I can.
Need anymore info, let me know.

My guess is that motherboard is limiting your ability to overclock your processor. I have heard, however, of people unlocking a second core on that version of the Sempron. I have no idea how to go about doing this though, and there's a possibility that your chip won't be able to unlock.

Very interesting. Thanks for pointing me in the right direction, I'll definitely research that. I'll post back if I am able to unlock a second core.

Only certain motherboards can unlock the second core. Mine, not being one of them. But I have another question, since this is a noob post. What is the "SB Reference" clock? I can set it to 500 (the max) with seemingly... nothing really happening. Temps are the same, performance seems to be the same.
post #7 of 9
Should be your south bridge ref clock; basically controls the speed of the I/O to hard drives, USB, etc. I wouldn't recommend messing with this too much, if any at all. Same with the pci express reference clock if you see it.

Thanks for that. I found out the problem with my previous overclocking attempt. It was overclocking the memory with the processor to insane amounts, but there was no option for changing the FSB:DRAM ratio, so I had to underclock the memory, by the timing to DDR-800. I also switched CPUs in between that last post. >.> I put in an AMD Athlon II x3. Got it at stable at 3.975GHz. I'm happy with this.

Good to hear you got it working thumb.gif
