***! Can't seem to get more than a barely stable 1.76GHz out of this chip! There's only two things I haven't tried yet...BIOS update or upgrade my 350W PS running 2 hard drives and etc.

Know of any sys status apps so I can diagnose the prob when crashes or freezes?

Gives us a bit more info on what you have already done so far. It will give us a general idea on how to better help you.

Well, I've gone up to 142 * 12.5 but will crash or freeze under simple processes like bringing up the display properties. I've tried upping the core voltage to 1.875 with no overclocking or stability gains (even @ 142 * 12.5). All of the latest drivers are installed (though that could be a problem)...61.77 nvidia driver and the original 42302e31 MOBO bios.

You name it, I've tried it. My pcmark scores suck and btw i have good ventilation (i don't even have the covers on my case!) Even after 10 runs of the SANDRA burn in, my CPU temp only inc 4deg.

I'm lost... I want a new CPU, but think i should figure this out first. Thanks for the help.

The problem is that is a KT 400 Via chip motherboard. It does not have a agp/pci bus lock. When you raise the fsb, it also raises the agp/pci bus. You can damage your data and your HDD if it gets too high. You will have to see if you have divider (ratio) locks no that board. If the fsb is 166 mhz, the divider should be set at 5( 5:1 ). This will set the agp/pci at 66/33 on 166 mhz fsb. You should be able to get up to 72/36(about 180 mhz fsb ) on the agp/pci without any stability problems. At 200 mhz fsb it will need a lock of 6 ( 6:1 )

I'm sorry, that board has a agp lock but doesn't have a pci lock. You should be able to lock the agp at 66 mhz.

From what i've researched, i don't think i have a bus lock on this mobo. is there a way to unlock?

i've updated my bios with no perf increase...still @ 12.5x141. i'm going to try a new power supply 500W v. 300W and see if it might help me post @ some of the higher settings. I really don't think it's a cpu temp thing (even my SANDRA benchmark reports decreasing temp over 10 runs).

I'm scared to change anything with my memory being a memory dip***** and all. Any info on changing these bios setting would be a great help--all my memory settings are default, though since i've updated my bios these have all changed, so I'll have to check. Thx for the info, dudes.

I think what he is trying to say is that you need to lock the agp/pci in order to be able to up the fsb without stability problems. you need to keep your agp/pci locked at 66/33 to avoid stability problems as well as greater possible problems.

One concern might be the GPU overclock. Try running it at stock (if yo u aren't already) and see if the problem is still there.

The pci bus is deffinately a good though and something to pay attention to, but if he can't get 142 * 12.5 to run stable, most likely the pci bus isn't causing the problem. When he's at 142mhz, the PCI bus = 142mhz(1/4)=35.5mhz. Which is under the 36mhz limit. 52.5C isn't too high of a temp, but it's getting up there. What heatsink do you have? Do you know if your 2000+ is a palomino core? Those things are pretty hot and don't overclock well. You can find out what core it is by running WCPUID or CPU-Z and seeing the model number. If I remember right, a palomino is a model 6.

Can I infer that I am not destined to go any higher than a 144 fsb with an unlocked pci/agp? I don't know whether I have a polomino core or not and I'm getting my temp from SANDRA so it might not be accurate.

Seems to me that a different chip would not solve my problem...sounds like i'll need a new mb if I wan't to have any fun. Thx for the bad news DeathONator...i've upped your rep.

WHen you up the FSB above 166mhz, the divider wil turn to 1/5. So then you can go from 166mhz to 180mhz. Then your mother board might have a 1/6 divider once you get above 200mhz FSB, if so your can take the FSB up to 216mhz.

Your memory will limit your FSB just as your mobo will. if you can lower your FSB to a stable setting, then up the multiplier with out seeing any instability, your FSB is limiting you, if running at say 133x13.5 isn't stable, then your CPU is causing the instability. Simple enough?

swammi · 10-01-04

Thx death...but can you explain this to me...this is a table of stable fsb upping the mult and decreasing speeds (from MBM).
14112.51762.5141141763141171761
It would seem that the fsb is the issue. I've seen people post 166 fsb with my mobo and cpu but I can't get above 141. Is it the palomino core that is the bane of my existence or am I just retarded? Don't answer the last one.
