Okay, I have a pretty conventional reasonably priced gaming system.

However, I had a bit of trouble overclocking from the BIOS. My motherboard designer, Soltek, is a sort of weird Asian company and hasn't yet released a version of its overclocking util compatible with 939 socket motherboards, so it's really my only option.

So, I tried setting my comp to a relatively easy OC by taking it to 220mhz on the HTT. It runs fine and cool, etc, until I try to restart the computer with windows. It fails to reboot until I manually press the reset switch, at which point it works fine. Also, I tried overclocking it a little more (about 250 at 11x, I guess?) and the computer just wouldn't start up. I got long-beeps from my mobo as it tried to startup unsuccessfully. Eventually had to reset the CMOS manually to get it to work.

I can only assume that the voltage wasn't enough to start up, and I need to change it a little bit from the stock 1.4. Any idea what might be a good safe voltage for starting up with an OC of about 250-270mhz with 11x multiplier?

Or, is the voltage even the problem?

Thanks in advance

That beeping is the memory failure .use a 333mhz divider and try again also up the v-core and the ddr voltage a touch v-core to 1.45 ddr to 2.70

I have my V-core at 1.64. But do that at your own risk. Youll need a good heatsink to go that high.

Keep an eye on your CPU temps as you add V-core.

It's your RAM. In the BIOS, lower RAM speed to DDR333, and I can almost guarantee you can hit 248x11 with that CPU without touching the vcore.

I've confused myself even more. The memory was the problem afterall, yes. However, the BIOS seems to be detecting my pc3200 DDR400 RAM as DDR 200 (it only gives me the option to set it as high as 250mhz). When I do set it to 250, that's when it gives me the long-beeps and won't start.

This is odd, because the computer itself (first startup menu) knows that it's DDR400 etc etc. However, in the BIOS, it defaults to 200. My motherboard may not support DDR400 in the DIMM slots I'm using, as it has a really bizarre DIMM config.

ALSO, when I clock the CPU to 250HT or so, it won't let me. I'll save the changes in the BIOS and restart, but when Windows comes up, my CentralBrain util (and the right click/properties on My Computer) register my processor as the default 2.2ghz and 200 HT, and when I go back to the BIOS, sure enough-- it set the HT back to 200, as if something isn't letting me up the HT by any significant amount. I doubt this is related to the memory, it's just odd. Any ideas?

EDIT:

It seems that my system has some sort of failsafe designed to keep it from overclocking so much that it won't start. IE, if it fails to start, it reverts the BIOS to 200HT and restarts. So... for some reason, I can hardly get it past [email protected] (2420ghz). Everytime I try to go past this, it either fails to restart or the BIOS reverts to 200HT. Maybe my Powersupply isn't cutting it? My "CPU voltage" = about 1.420 when I'm just surfing the web and nothing taxing is going on, with the "DIMM voltage" about 2.552. This seems to be right. So, if my powersupply is delivering enough power, I don't know what's keeping it from overclocking above 220HT. Still confused =/

pretty simple fix if you ask me. Your bios setting of DDR200 is your divider...200 = 1:1. I dont think it's telling you DDR200, i believe the option is just 200. Max memclock frequency or something. You also aren't changing your timings I believe. I will give you some numbers to try and should work, if it doesn't I suggest reading some overclocking guides..

246 x 11
Vcore 1.5
HTT x 4
Memory timings 2.5-3-3-7 (1T)
Memory voltage 2.7v
Memory divider (speed) 200 "DDR200" as you called it......1:1

that should be it, if you dont understand what this means, then you have some reading to do...good luck.
