What's my bottleneck?

post #1 of 18
Thread Starter 
OK i have a Sempron 64 2600+ which it 1.6Ghz stock on an ASUS K8U-X. before i did anything but changing bios options i could get it to 2.24 Ghz perfectly stable. Now here comes my problem, when i went any higher it would say voltage selected was too low so i didn't even try any higher because the Sempron doesn't support cool'n'quiet so i can't change the voltage in the bios. So i found a link to a pin mod for 754 CPU's and i got the vcore up to 1.45 V from 1.4 V but it only got me an extra 50 Mhz, once i get past 2.27 Ghz it won't post. I have tried to loosen the timings on my ram and limit the mem clock to the lowest possibility (100 Mhz which ends up bieng more), limiting the AGP to 4x instead of 8x, and turning down the HT to a 1:1 ratio. Nothing changes it so my question is: what is my bottle neck? my ram which was only $20 so that might be it, my Chipset? which is an ALI ULI M1563, or is it my 350 watt power supply? I can't figure out what i need to get next but i have seen people get this same processor with the same stepping much higher than what i'm getting so i would like to know.

If you're able to overclock from 1.6 to 2.27, then your motherboard and chipset aren't the problem.

If you're not pushing your memory too far, regardless of price, that is most likely not the issue.

If I were you, I'd set it back to AGP 8X because setting it to 4X is only going to degrade performance.

What is your FSB?

Can you give a screenshot of CPUZ?

Thanks

if i set it to AGP 8x it will post but when it loads windows it reboots

my fsb was 281

a CPU-Z screen shot is attached but i had to lower the fsb to boot again for some reason it only booted the first couple of times at 2.27 then i had to lower it to 2.25 to boot. idk why.

I would say its more likely a PSU problem there mate. Im betting the PC just cant give your system Enough Juice especially during an Overclock.

i think that is the max you can go without any more volts.

But that is a nice OC man!

Agreed.
Take an old psu out of an old comp laying about then connect the green wire on the 20 pin connector to a ground (black). Then, you can just plug things into your external psu ^^

Also, I can make an ISO of the T-Force OVERCLOCKING utility my board came with and send it to you so you can burn it to a disc and use.

sounds good man thanks

ok how do i turn on the external ps? the button would only work for one ps wouldn't it?

You have to turn the switch on and it'll power on. But that would work only for fans/lights and such, i wouldn't connect an HDD on that kind of setup...you would have to power both PSU "at the same time" pretty ackward. << Correct me if i'm wrong but that's how my wiretricked psu works.

But as far as I remember, you don't need to do the wire trick, just connect your hdds and such on it and leave the current one dedicated to the board and say graphic card. Every component should fire up when you turn on your PC.

Going to burn ISO right now.

And yeah, don't a HDD or any drive to it. Only use it for your cases fans, hsf, etc. The green wire is how the motherboard turns the PSU on. If you ground it, it's on as soon as you plug it in ^^

ok well that makes sense well i'm looking at that 500 w power supply on newegg free after rebate and i might just do that http://www.newegg.com/Product/Produc...82E16817159062
