FSB keeps going back to 200

[imported_Deez]

I set the FSB to 225 and boot up and it sees that change in bios and saves it. I see it on the post screen as being 225mhz, but when I get into windows it is at 200 again. I checked with cpuz and sandra. I even loaded up memtest and it says 200. So I turned off watch dog and that did not help. I was having problems at 225 being stable even with the the ram at 5:4 and loose timings. Then i bumped it up a notch in vcore and went for 230 and it worked fine. So I start doing sandra benchmarks and that is when I saw it was at 200. I have tried to change it several times and it never stays when I go into windows. If I reboot and check it in bios it stays at 230. I really have no idea what is going on so any help would be appreciated. Is there some sort of setting I am missing?

Does it stay put at lower frequencies say 212 or something?

Also What MB and CPU are you running?

Epox 4pda3i-3 and a p4 2.8c.

I am not sure I will check and see if it stays at a lower fsb.

Also is there a way to check the agp/pci speeds. I thought Sandra did, but I can't seem to find it.

Also you may try the "S&M" software monitoring/torture test tool. That seems to give lots of good accurate information as well. I don't know much about Epox boards so I can't really help too much. When OC'd is the clock frequency right using a real time frequency checker?

14x225 should = 3150MHz

IF so perhaps it is just a monitoring error on the softwares part.

Yeah it is right, if you go by bios, but everything else says it is 200. I checked it with 3 different programs, that I have seen change before with and OC.

Edit: I tried and it won't even sty at 205. I also checked to see if was faster even though it didn't say it was and it wasn't. I was able to use glockgen to increase the fsb adn it made it to 235 stable and it definataly mad a difference.

Anybody have any ideas?

Do you think it could be the board? Should I rma it, it is only a month old.
