Unfortunately, it appears your BIOS doesn't have all the necessary ingredients for overclocking. The manual shows no adjustments for memory or the Hypertransport bus & without them, you're not gonna be able to do much of anything. If you were able to get the CPU frequency up to 220MHz stably, be happy with that...I don't think you're gonna do any better.

i have adjustments for those on an increase in voltage only by .025v per hop up. so is there a formula to match everything up like everything .025v increased or??? i was fooling with it last night and had only 1 stable run.

You're not understanding what I'm telling you. To be able to successfully overclock, you HAVE to be able to change the RAM, PCI-e & Hypertransport (HT) bus settings...not just the CPU frequency & voltage. When your CPU freq is at 200MHz, the HT bus is at 1000MHz, the PCI-e is at 100MHz & your DDR2-800 RAM is at 400MHz. But when you increase the CPU freq to 220MHz, the HT bus jumps up to 1100MHz, the PCI-e bus jumps to 110MHz & the RAM jumps to approx 440MHz. The overclocked HT bus, PCI-e bus & RAM are what's making the system unstable, not the CPU. Your BIOS does allow you to lock the PCI-e bus at 100MHz, but it doesn't provide adjustments for the other settings. Your CPU is definitely capable of running at a higher freq, but the HT bus & RAM are not. In other words, you're board was not designed with overclocking in mind & there's not much you can do about it. But just in case there are settings in your BIOS that don't appear in the manual that I downloaded, here's what you've gotta do: - lower the RAM speed from DDR800 (400MHz) to DDR667 (333MHz) - lower the HT (LDT) bus from 1000MHz (5x) to 800MHz (4x) - lock the PCI-e bus at 100MHz - disable Cool 'n' Quiet - disable all Spread Spectrum settings - increase the CPU freq 10MHz at a time, testing the system for stability aftr each increase. Increase the CPU voltage only if necessary to stabilize the system. Try to get the freq up to 250MHz.

Say I have a MOBO with DDR2 1066 Standard And a 1333/1066 STandard for CPU. I buy DDR2 800, and a CPU with a 1066 FSB I can OC walk the RAM up to 1066 and the CPU to 1333. But when I walk the CPU to 1333 its gonna want to send the RAM to that too isnt it? WinXP Pro 64 Bit AMD X2 5200 Windsor Gigabyte M57SLI-S4 Corsair XMS2 2GB DDR 800 EVGA Geforce 7950GT 512

OK, now you're asking about an Intel system...they are totally different & the overclock requirements are totally different. Ideally, you want the CPU frequency & RAM frequency to run at the same speed (aka, 1:1 ratio). Remember that Intel quad pumps the FSB & RAM is only double pumped, so you'll have to reduce these to their actual frequencies to help you to sort out the correct settings. If you have a 1333MHz FSB CPU & have no intentions to overclock, all you really need is DDR2-667 RAM. 1333MHz FSB /4 = 333MHz frequency DDR2-667 /2 = 333MHz frequency However, if you use DDR2-800 or DDR2-1066 RAM with a 1333MHz FSB CPU, the memory setting in the BIOS should still be set at DDR2-667, then when you overclock the CPU freq, RAM freq will always stay at 1:1. Just to add...if you have a 1066MHz FSB CPU (266MHz freq), all you need is DDR2-533 RAM (266MHz freq) or higher rated RAM underclocked to DDR2-533.

Ok good so an ideal system for intel is 1066 FSB on the CPU, 1066 DDR2 RAM, and 1066/1333 capable MOBO. Quad core runs at 1066 on the Q6600. This setup is for no intention to OC at all just have a perfect PC.

No dude, wrong again. If you're NOT gonna overclock, this is how you should pair up the CPU/RAM: 1066MHz FSB CPU / DDR2-533 RAM 1333MHz FSB CPU / DDR2-667 RAM If you ARE gonna overclock, you'd wanna use higher rated RAM, but it should initially be set to the speeds I listed above...that will give you the 1:1 ratio that I explained. Then when you increase the CPU freq, the RAM freq will stay in step.
