No Overclocking Stability?

post #1 of 5
Thread Starter 
Before I describe the issues, I feel it would be beneficial to list my components first:

Motherboard: Asus K8V SE Deluxe
CPU: AMD Athlon 64 3200+ (2GHz)
Graphics Card: Radon 9700 Pro
Ram: 1.5Gb DDR 400 (PC 3200)

The maximum FSB I am able to achieve with any sort of stability is 225 Mhz. If I exceed this I get one of two problems, both which negate any booting ability; An error asking me to select a device to boot off, or a message saying <windows root> system32\\hal.dll missing or corrupt (which thus far has only been amended by reinstalling Windows).

I have increased the Vcore voltage to 1.7 (cooling is more then sufficient, CPU temp was 31 degrees), lowered the multiplier several values, the lowest being 6X. I set the CPU clock : Ram ratio at 2:1, to no avail. HT Frequency has been set at 600mhz, 400mhz and 200mhz, again with no advances.

Surley i should able to acheive a much higher FSB then that. I am aware that CPU's can vary in performance, but should lowering the multiplier not (at the very least) allow for some slight increases?

I can only hold two things responsible and those would be either the Hard Drive (10000 RPM 70gb SATA), or the CPU itself. Is it possible that a hard drive could affect results to such an extent? Should I load windows on an old IDE hard drive?

Thanks for you time

Rory

Hi and welcome to Overclock.net, please fill in your system specs under the userCP tab, that way its easier to help you with problems......
When you raise your FSB everything in the system goes up with it, unless you configured otherwise. This instability is possibly caused by your ram, make sure that you have locked your AGP/PCI bus to 66/33, set your multiplier/ram timings/speeds manually,
Check your cpu temperatures @ 100% LOAD with for example:speedfan
return to stock settings and overclock step by step, test with memtest and prime when your system gets instable run a divider on your ram, and try to keep the HTT under or on 1000. (when you raise it to 230 make sure its on 4x/800, when you go higher than 250, it should be @ 3x/600
The cpu voltage is the last thing you raise if you OC, your temperatures will go up alot as a result of the higher voltage....

Cheers. Just need to reinstall Windows and i'l get started Could the Hard Drive have anything to do with the result?

i believe its your sata controller causing it when you OC, if you are not sure as soon as you installed windows you can test your drive(s) with hdspeed and hdtach..... found here

Ahh. Upon browsing overclocking forums i came across this:

"However, the early Intel chipsets, SiS chipsets and all VIA chipsets do not know to lock the frequencies at their nominal values. In reality it means that if your mainboard is based on VIA K8T800 chipset, for instance, you will not be able to go beyond 225MHz FSB frequency during overclocking. Even if your CPU can do better than that, you will have to stop at this point, because the system will not recognize the hard drives any more, or because the integrated sound on your mainboard stops working."

This seems to be my exact problem. It mentions a partial solution:

"I mentioned the older chipsets that cannot lock the AGP and PCI frequencies at their nominal values. It is true, they cannot support the nominal frequencies of these busses throughout the entire FSB frequency range. But they have to keep these frequencies at nominal when the CPUs work at their standard clock rates. This is done with special dividers that switch automatically depending on the FSB frequency. The standard frequencies in this case are: 100, 133, 166 and 200MHz.

Suppose that we overclocked a Duron processor from 100MHz to 120MHz on the bus and it remained absolutely stable all the time. But when we increased the FSB frequency to 125MHz, some freaky things started happening and the system would even refuse to boot at all. Of course, we could have reached the top of the CPU overclocking potential, but it could be a completely different reason. What if the CPU can go much farther than that, and it is the higher AGP and PCI bus frequencies that do not let us continue? You can check it out pretty easily: set the frequency to 133MHz. In this case the mainboard will use different dividers to set the bus frequencies to their nominal values. If your CPU copes with this overclocking, you will be able to go somewhat higher."

I really don't understand the mechanics behind this. If someone would be so kind as to explain/elaborate. Should i set my FSB to 233MHZ? Could i prehaps download a program to lock the PCI/AGP frequencies?

Once again, thanks for any replies.

EDIT: "The Asus K8V Special Edition Deluxe board is built around the VIA K8T800 chipset"
