8rda oc problem, help?

[King_of_qb]

when i try to go to 202 fsb and up the board gets unstable and has agp tearing can anyone help me.
i know it is not my ram and cpu and also i have set the agp lock to 50, 66, 67, and 68 and still the same problem

right now i am runnig 11.5 x 200 stable

do you cool your northbridge active ? if not - you should do this =)

[King_of_qb]

yes i have a zalman gold nb hs with a 40 mm fan on top

[xtreme]

hmm strange... do you share your AGP slot with another card?

[King_of_qb]

no, no pci cards

[xtreme]

hmm quite same problem here... all over 200FSB gives me unstability

[Justintoxicated]

what bios are you using? im stuck at 190 FSB with a vantec iceburg on the chipset.

[Bushboy]

I really dont understand this board, mine can do 228FSB no tearing (held back momentarily by OS) and higher...With just a 90mm fan blowing across the NB. Seems like there are really good boards and some not so good ones...Mine's rev 1.0 too

[Method Man]

I got the same problems...when going over 200FSB the screen starts to flash like when you change the refresh rate.I think its the south bridge thats keeping us back because I have a Crystal ORB on the NB.


Right now I'm running at 200x11.5 stable

[xtreme]

hmm have the rev. 1.1 ... i almost think, its the rev... :banana::banana::banana::banana::banana:ty rev. 1.1

[Method Man]

Mine is a Rev. 1.0

[xtreme]

hmmm then this must be just a little thing... @ bushboy.. do you changed some jumpers or something ?!

[Bushboy]

Nope no jumpers off, but I did take the TIM off and put some ASIII on, which really helped. The TIM is a POS and the actual area that the heatsink touches the NB is like 1CM squared IIRC. Active cooling like a 90mm fan or watercooling is really necessary.

I just put a TEC on it, and it's so much better. Up to 224FSB stable and climbing...Basically burning in every so often.

[xtreme]

hmm will try tomorrow...

Can you guys with the same board give me some feedback on this? :

i have tried removing the fsb jumper but it has not helped and i am using the official c10 bios

[xtreme]

hmm bushboy, what cpu ???

[Bushboy]

XP2400+ I put the stock heatsink back on (yeah that POS) to make sure it's definately the cause, and even put a 120mm delta screamers right on top, but it wouldn't do 224 stable at all. I was setting it to 224 x 10 if you want to know. The NB is definately limiting.

[xtreme]

hmm my stock sink on the NB is pretty cool now... can't imagine, thats the the reason

also put a 30cm ventilator in front of the pc... doenst brought me a MHz :/

[Bushboy]

Yeh but the stock heatsink makes very little contact with the NB, so it doesn't get as hot as it should be. I thought mine was running cool, until I felt under the PCB!
