Do I need to reinstall Windows when I set FSB Strap?

I have 2x2GB OCZ Platinum DDR2-1000 memory sticks running in dual channel mode at 800mhz on my ASRock P45XE motherboard. I want to get the ram to run at 1000mhz, so I set the FSB Strap to 266 and set the ram to 500mhz (1000mhz) DDR2. The computer would boot fine, but when it came to loading Windows, it would say the file is corrupt and that the checksum doesn't match. I have tried numerous things, from raising the Vcore, ram voltage and NB voltage and even screwing with the timings to no avail.

Can anyone help me out on this? I would really like to get it to 1000mhz so then I can OC it 66mhz to reap more ppd for the Fold-A-Thon on Saturday.

Bascially this means your Overclock is UNSTABLE and is causing Windows to either corrupt its files or not load correctly.

Further Overclocking your system or making any further attempts will likely make your life worse. Reset everything to stock and try loading into Windows. If you cannot then you may need to repair your windows installation.

Everything works fine when I set them to stock. I can push the FSB up from 333 to higher values without issue, but when it comes to strapping the FSB, then is where I get the issue.

Well the FSB Strap seems to be your issue. Perhaps you should leave that alone.

If you used the jumpers, try setting them back to stock see if it helps. The jumpers are really for lowering the ram dividers. If you leave them at default position, just oc the fsb to get your ram higher. Like Enterprise said, it could be that the oc is unstable corrupted some Windows boot file. You can try a repair install. Asrock's P45 chipset boards don't play well with high performance rams, you might want to go into bios and make sure the ram timing and voltage is set to the manufacture's recommeded values.

Never thought of that. My ram is rated 1000mhz @ 2.1v with 5-5-5-15 timings. Currently, it runs at 800mhz @ 1.79v with 5-7-7-24 timings. I will tighten the timings on my ram

Oh, and it doesn't corrupt the windows file as you may thing, it just says that it is "corrupt" or the checksum is bad, but I when I put it back at stock, it boots normally.

When that happens, does it give you an option to press F1 to continue booting?

You can try oc'ing it in Windows with OC Tuner, if the computer freezes then I guess the mobo just don't like running the ram at 1066. But if it's stable, you can set OC Tuner to load oc profile on start up, so it gets around the issue.

So for now, I have the following:
FSB = 351 mhz
multiplier = 7x
speed = 2520mhz
vCore = 1.10
memory voltage = 1.90
Timings = 5-5-5-14
vNB = AUTO

Mainly a bit of undervolting and a little overclock. Nothing too fancy, don't want to overdo it and burn out this system since it took so long to get the funds for it.

Try setting the vNB to "Middle" (if your bios gives the same option as mine).
