Amd 64 overclocking problem...sorta????

[lestat0521]

Ok here is what i have,
AMd 64 3700+ clawhammer 1mb l2, soc754
Nvidia K8n Neo Platinum mobo
1gb ram
ect....

I read the quick and dirty oc guide and started in on trying to overclock my cpu.

When attempting to find my boards max FSB i run into a strange problem.

At 220 mhz it boots fine, as soon as i increase it to 221 or more it tries to boot but before it does it goes to a screen that says this:

"Nvidia raid rom bios"
"detecting array......"

Once it gets there it sits and will not boot. I don?t not have a raid setup, in fact i checked the bios and the raid feature is disabled.

I have already tried switching to my 3rd and 4th sata connectors for my two drives.
I already tried only hooking one drive up and trying to boot.
I already updated to newest bios ect.

None of the above worked.


EDIT: IF anyone has a link to modded bioses please let me know

Any help would be much appreciated.....THANKS

Set the PCI/AGP buss speed to 67 in bios, I believe thats what locks the buses on that board

didnt work, any other ideas?

Have you dropped the HTT multi (LDT) to 3x? Your boards hyper transport bus speed is 800mhz so if your running 220x4=880mhz (too high), you need to keep it right around 800 or lower. At 3x your probably good to up to 280x3=820, any higher than that you will have to drop to 2x

You also probably need to run a ram divider (mem speed of 166/DDR333), unless your ram can handle overclocking past 220, if it can you will at least have to increase the DDR volts and/or loosen the ram timings. And you will have to increase the CPU volts at some point as you raise the HTT

Try

HTT multi = 3x
CPU multi = 12x
HTT =220
ram mem= 166/DDR333
CPU volts= +.025 or +.05

Then bump it up 2-3mhz at a time testing for stability as you go


You can aslo try

HTT multi = 3x
CPU multi = 11x
HTT =240
ram mem= 166/DDR333
CPU volts= +.025 or +.05

This will run your ram at 200mhz(stock) and slightly overclocked if you can push it farther. I run my SD3700+ (s939) at 255x11=2805, you probably can't get that high but who knows

Well i dropped the ram divider to 100spd, causing it to run no where near its limit, i also dropped the htt multi to 3, and upped the volts to 1.63 because i have a .13n chip, and put the cpu multi to 6x to take that out of the equation, but none of that worked

That definately sounds like a mobo or bios issue. Does that board have adjustable chipset voltage? If so you might try bumping it. But just shy of 2.7 isn't shabby for that chip.

o, well i figured i could get more then 2.7 out of it.....

No chipset voltage on that board.

Try the official 1.8 bios, some people had problems overclocking with all the BIOS' after and including 1.9, you don't gain anything from those BIOS' unless you run dual core anyway.

I doubt it's the LDT multi, I have that board (just haven't updated my sig yet) and can run at least upto 260 with a 4x multi.

thx mogadon ill give it a try tonight, till then any other info as why it may be doing this?
