I am having some troubles overclocking with 4GB of RAM in Vista. Does anyone know the limitations of overclocking with 4gb RAM?

On XP and with 2GB in Vista I managed this overclock below and it was stable as.

[email protected] - 475 fsb
2gb geil pc-6400 (2x mem multi) 5-5-5-15 timings @2.3v
Gigabyte DS3 rev 1.0 F12 bios.

I loaded optimized defaults from bios, turned off, added memory, booted into windows to see if it actually recognized it, it did. So I went back to bios went back to my old overclock and it didnt boot. Then it restarted, booted into windows but bios had set everything at stock.

Then I went into bios and set it to 429 FSB (3Ghz) and after about 5 minutes I got a blue screen error :(

If anyone has any advice on overclocking with 4gb then I would be very grateful.

Thanks in advance.
 
4gb is going to be putting a lot of strain on the Northbridge, so you may find it needs a voltage bump.

Also, you may also find that it will be nigh on impossble to get to the same FSB with 4gb.
 
Ok cheers I will try that.

Just to add, I notcied an option in the bios for memory. You can select Option 1 or Option 2. The small description says that if RAM is unstable use option 2.

So I used option 2, loaded into windows at 450fsb and ran Orthos for just 15 mins to see if it was stable and it was as it wouldnt even boot before at a higher fsb, and crashed just sat on desktop at 429 fsb. Will try same OC as before and giving Orthos a good few hours.
 
Cant seem to get it to boot at any FSB above 430, I am thinking of getting another chip with a 9x Multi then I wouldnt have to push my RAM as hard, am I right in thinking this?
 
4gb has really put a limit on what FSB I can have, but in all fairness I have only lost 300Mhz on my overclock, probably wont see any real world losses on that.
