I can't get stable higher FSB than 500

Have you read the overclocking guide?

Yes, there is no answer for my question.

You're probably going to need more NB/VTT volts to get that high of an FSB stable.

Higher then NB 1.35 and VTT 1.30 ?

Yeah why not? Try it and see if it helps.

Now I can't even boot to bios after increase FSB over 500, PC is restarting all the time.
When I increase voltage of CPU to 1.28V, NB to 1.2V and VTT 1.2V nothing is changing, reset all the time, but when I increase any of voltages higher I get long loud beeeeeeeeeeep and after I have to turn off PC, when i turn on bios is restarted.

You are going to need more than 1.2v or even 1.35v NB to run at 500+ fsb.

Try 1.4v or even 1.45v, but as you increase your NB voltage, you may need active cooling on it.

On NB i have water block so no worries.
To by more specyfic:

voltage on CPU - 1.28, NB - 1.2V, VTT - 1.2V and FSB higher then 500 PC is restarting all the time I need to Clear CMOS

now when I increase any of voltage higher then i wrote above I get long loud beeeeeeeeeeep. One thing what I can do is to turn off PC, when I turn it on again the BIOS is restarted.

I checked voltages: CPU - 1.44V NB 1.45V and VTT 1.35V PC doesn't beep but reset all the time.

I dont now how but I'm running now 510 FSB for ower 6 hours in prime95 with no errors, voltages are 1.28 on CPU, 1.18 NB and VTT 2.1.
Ram is working on 1020 so not even on stock (1066).

I will try to go higher.

No luck, over 515 (try eve 550 and 600) restarting all the time or long beeeeep, I try with low multipler X6 but no changes, try to set other divider to memory but no result, set more voltage on mem and higher timings no result. I increase NB to 1.45 and VTT to 1.35 CPU to 1.46 no results.

I belive that this CPU and NB GTL REF are important but how and when to change it thats the question.

I think i found reason of my issue, MEMORY. I started to test it in memtest86+ and after few minutes i have 250 errors. When I get replaicment I will let You know how Im doing.

Ok guys I have now OCZ Reaper PC2-9200 and another problem, I can't get this thing working.
On auto motherboard decting it as 667mhz and its fine windows is booting Prime without problems memtest too. If i set it on 800mhz it alright too, but if I want to push it higher mobo don't want to boot.
I've try like on the stickers timings 5.5.5.15 or 18 + 2.1 voltage mobo doesn,t boot on 1066 and 1150mhz.
Please help
