Blast from the past OC help

post #1 of 11
Thread Starter 
Okay, I'll keep this short and sweet.

I'm running a terribly old system:

AMD 4000+ Single Core socket 939 (http://www.newegg.com/Product/Produc...82E16819103529)
2x1 GB G.SKILL DDR 400 RAM (http://www.newegg.com/Product/Produc...82E16820231047)
NVIDIA 6800 Ultra AGP by BFG
(http://www.tigerdirect.com/applicati...3309&CatId=935)
Abit AV8 Mobo (http://www.newegg.com/Product/Produc...82E16813127181)

I am building a new computer this upcoming week (THANK GOD). However, I need to squeeze as much out of my current system until I have my new one up and running. I play counter strike source competitively and this week's league map give me terrible FPS.

Here are my current settings in BIOS:

FSB: 205 (200 is stock)
Multiplier: 12 (stock)
CPU Voltage: 1.350 V (stock)
AGP Voltage: 1.55 V (stock)
RAM Voltage: 2.70 V (stock)
Northbridge Voltage: 1.55 V (stock)
Southbridge Voltage: 2.50 V (stock)
Hyper Transport Voltage: 1.20 V (stock)


I have zero OC'ing experience. I was told to increment the FSB by 5-10 MHz at a time. Trouble booting? Try increasing CPU Voltage and makes sure temps don't get too high. Rinse and repeat.

My issue is that I CANNOT get this thing to be stable at anything higher than FSB 205, which is pathetic (The CPU should be able to get up to 2.7 GHz on the stock cooler, 2.6 GHz at the very least). If I put the FSB at 210 with everything else stock, I get blue screens. If I increase the CPU voltage in its smallest increments all the way up to 1.5 V, I still get blue screens.

Blue screens usually mean memory problems, right? How would I go about trouble shooting this? I've increased my RAM voltage to 2.80, but to no avail. I have also undervolted it to 2.60, also to no avail.

Currently temps are 30 C idle and 50 C load. Temperature shouldn't be an issue, at least on the CPU side of things. This very same CPU was running at 60 C idle and 90 C load with no issues before I cleaned 6 years of dust out of its heatsink, so I know it can take the heat. I'm not sure about RAM because I don't really know how to monitor it. I'm currently using:

Core Temp
CPU-Z
Everest
and ORTHOS

for testing.


Any suggestions? Tips? Pointers? Anything?

Yes sir. Every increment from 1.35 V - 1.50 V. Temps are still perfectly acceptable at 1.50 V. Way lower than my old pre-heatsink cleaning temps. But I still get blue screens.

maybe lower the northbidge multi by one. or up the north bridge voltage a litle.

Dumb question, but is the Northbridge Multi just the Multiplier? Or is it something else?

Anyways, I just tried the following settings

CONFIG 1:

FSB: 210
Multiplier: 12 (stock)
CPU Voltage: 1.375 V
AGP Voltage: 1.55 V (stock)
RAM Voltage: 2.70 V (stock)
Northbridge Voltage: 1.60 V
Southbridge Voltage: 2.50 V (stock)
Hyper Transport Voltage: 1.20 V (stock)

CONFIG 2:

FSB: 210
Multiplier: 12 (stock)
CPU Voltage: 1.400 V
AGP Voltage: 1.55 V (stock)
RAM Voltage: 2.70 V (stock)
Northbridge Voltage: 1.60 V
Southbridge Voltage: 2.50 V (stock)
Hyper Transport Voltage: 1.20 V (stock)

CONFIG 3:

FSB: 210
Multiplier: 12 (stock)
CPU Voltage: 1.400 V
AGP Voltage: 1.55 V (stock)
RAM Voltage: 2.70 V (stock)
Northbridge Voltage: 1.65 V (maximum allowed)
Southbridge Voltage: 2.50 V (stock)
Hyper Transport Voltage: 1.20 V (stock)

CONFIG 4:

FSB: 210
Multiplier: 12 (stock)
CPU Voltage: 1.425 V
AGP Voltage: 1.55 V (stock)
RAM Voltage: 2.70 V (stock)
Northbridge Voltage: 1.65 V (maximum allowed)
Southbridge Voltage: 2.50 V (stock)
Hyper Transport Voltage: 1.20 V (stock)

CONFIG 5:

FSB: 210
Multiplier: 12 (stock)
CPU Voltage: 1.450 V
AGP Voltage: 1.55 V (stock)
RAM Voltage: 2.70 V (stock)
Northbridge Voltage: 1.65 V (maximum allowed)
Southbridge Voltage: 2.50 V (stock)
Hyper Transport Voltage: 1.20 V (stock)

CONFIG 5:

FSB: 210
Multiplier: 12 (stock)
CPU Voltage: 1.475 V
AGP Voltage: 1.55 V (stock)
RAM Voltage: 2.70 V (stock)
Northbridge Voltage: 1.65 V (maximum allowed)
Southbridge Voltage: 2.50 V (stock)
Hyper Transport Voltage: 1.20 V (stock)

CONFIG 6:

FSB: 210
Multiplier: 12 (stock)
CPU Voltage: 1.500 V
AGP Voltage: 1.55 V (stock)
RAM Voltage: 2.70 V (stock)
Northbridge Voltage: 1.65 V (maximum allowed)
Southbridge Voltage: 2.50 V (stock)
Hyper Transport Voltage: 1.20 V (stock)




All resulted in blue screens within a few minutes (sometimes seconds) of start up. The ones that gave me time to load up orthos and core temp showed perfectly acceptable temperatures at load.

I'll guess I'll try to mess with the multiplier? If that's what you mean by "Northbridge Multi"

Just tried:

FSB: 210
Multiplier: 12 (stock)
CPU Voltage: 1.400 V
AGP Voltage: 1.55 V (stock)
RAM Voltage: 2.70 V (stock)
Northbridge Voltage: 1.55 V (stock)
Southbridge Voltage: 2.50 V (stock)
Hyper Transport Voltage: 1.20 V (stock)


Ran MemTest from a bootable disc for half an hour (1 complete test) with no errors. Booted up Windows afterwards and blue screened within 5 minutes.

This is getting to be very frustrating. I don't know what I could possibly be doing wrong.

The north bridge should be a separate multiplier.
What are the temps you are getting? because the higher the temperature the more unstable the processor can be.

Update your motherboard bios. There are reports that the PCI/AGP lock didn't work with older versions. You're actually in danger of corrupting your hard drive if your PCI lock is not working.

Lower your RAM ratio, lower your HTT multi, ect. You don't want to be overclocking anything except the CPU. Overclock the other parts later.

Hmm, I'm not seeing a north bridge multi in my bios. I'll keep looking...

And even at 1.5 V, I'm not getting anything over 40 C idle and 60 C load. As I said before, this very same CPU was running at 60 C idle and 90 C load before I cleaned out the heatsink. At stock voltage I'm at 30/50. Really doubt heat is the problem, but who knows at this point

60C should be a concern. You want to keep load temps 55C and under as a general rule of thumb. If you weren't building a new computer, I would suggest a better cooler.
Edit: Don't turn your voltage up to 1.5 if you're getting that heat. The only thing the cpu voltage will let you do is get a higher OC, but those heats aren't acceptable.

On the same topic, I suggest you get one anyways. Get one that fits the form factor of your case and the socket of your new cpu. It would be much much easier to overclock it.
