Cant set multiplyer settings in BIOS

For some reason, when I boot my PC, it was automaticly OCed to 2470 MHZ. This caused one of my games to crash after a while. So I had to use this OC software (Easytune) that came with my mobo to bring the clock back down to stock speed. But I never could get it all the way back down to 2400 MHZ where is should be, only to 2412 MHZ at the lowest. After messing around in the BIOS, I found one setting for the RAM timing or muliplyer. The selections in this setting are 1T through 5T and an Auto setting. I had it set on Auto. So I set it to 1T. This braught the clock speed down to 2412 by default so I wouldn't have to use the OC software in XP to bring it down every time I restart. But I'd like to bring it all the way down to 2400 MHZ and I cant find the friggin multiplyer settings to bring the HT bus speed to 200 MHZ instead of 201 where it's at right now. My mobo is a Gigabyte GA-K8NF-9 (nForce4 chipset). Thanks in advance for any help anyone can provide!

PC Specs:
CPU: Athlon 64 4000+ Clawhammer core
Mobo: Gigabyte GA-K8NF-9
RAM: 4x 512 MB Corsair PC3200 (DDR400)
Graphics Card: PCI-E 256 MB ATI X850 XT PE

That's about all the important stuff...

Googled around and came up with this.You have probably been there but I'll post it just in case.Don't know if it will help.

Regarding the overlocking and the tuning options of the components Gigabyte gave the BIOS
several options, which are made accessible partially only with a hidden CTRL+F1 key combination.
Because it's possible to get further features in the BIOS, if one presses CTRL + F1 key, since this releases the Advanced chipset menu with many memory timing and the HT clock options.
Whereby other important voltage adjustments e.g. Vcore (CPU), VDDR (memory),
PCIe core voltage are alterable without this key combination.
Furthermore all frequencies are extensively alterable like the host frequency, memory frequency
and PCIe frequency, so it's very easy to overclock with this mainboard.

 

Dont bother using Windows baes OC programs, we can solve this in the BIOS.

RAM settings wont change your CPU frequency at all, though sometimes you'll find CPU settings on the same BIOS menu as RAM settings.

I also strongly doubt that a 70mhz 'overclock' would be causing freezing or crashing in your games, but that depends on what the HTT is set to and if your RAM is handling it well.

You should easily be able to set the HTT to 200mhz, but again, not all BIOS call it HTT, so look around for what it could possibly be called. (your motherboard manual doesnt seem available on the Gigabyte Website, so I cant look for you)

Also, you shouldnt have any thermal problems unless your Heatsink is not seated correctly with thermal compound on it, providing you have the vCore (CPU Voltage) set to default.

Also keep in mind that something as small as a 12mhz 'overclock' is very common with Spread Spectrum enabled. its a very minute amount, and really woudlnt be the cause of any problems.

I suspect there is another culprit in your case, be it a hardware issue or a faulty driver.

 

Thanks guys. Franklin, I knew about that CTRL + F1 function in my BIOS. Sorry, I forgot to mention that. I pretty much instinctivly hit it every time I'm in the BIOS I dont really think about it, heh. I still have the mobo manual that came with my mobo too, but I have flashed my BIOS a few times since I've had it, so there are many more options and slightly different menu layout since the original BIOS version. That might be why I can't find the multiplier settings so easily now.

Also, I didn't think that that small of an OC would cause any harm to my PC or games either... and it didn't until I got Battlefield 2. That game is already a bit buggy as it is, heh.. but I definitely got the pattern that whenever I left the CPU clock at 2470 MHZ, it would eventually slow my game down and crash. It stopped after I braught the clock down.. this is pretty much the only reason I care about it, because I play this game a LOT and I want it to run well. The app. I use to monitor my clock speed and mulitpler stuff is CPU-Z. It says my multiplier is at 201, so I know that's why it's at 2412 MHZ.

I'll try disabling spread spectrum in the BIOS and see what that does, I know I saw it in there. Thanks, InYearsToCome.

Also... a little OT, but do you think I would get that much of a performance difference if I upgraded my Mobo to one that has a 1 GHZ HT link from mine that has 800 MHZ? I know my CPU is designed to run at 1 GHZ FSB, so I kinda have a bottleneck in there. As cheap as nForce4 mobos are now, do you think it's worth it?
