Need Help choosing RAM

My NF7 has been giving me problems with its multipliers over 10x(despite various BIOS)

Since my OC is not where I want it to be Ive decided to get better RAM. I currently have CH-5 and since BH-5 isnt available anymore here is what I am considering:

Possibly this (for some reason I think this may use BH-5)

I know it may seem like a stretch but I am really tring to push my NF7 into the 250mgz range. These are all the ones I could find on newegg that seemed promising. I am leaning more towards the first link for the PC4000 Geil. I could care less how it looks, I just want it to run @ 500mgz.

Im looking to spend about $140-150 for 2x256MB. The goal is to get it to run atleast 500mgz on my XP. That way I can justify getting an NF7 and make good use of the PCI lock.

Any suggestions will be greatly appreciated.

check my sig.. if u like it, then choose geil

I'm sure you've heard this before, but just to repeat. High latency memory and AMD don't mix. But if your dead-set for running a 500MHz FSB, for whatever reason - although performance wouldn't really be the top one - I would recommend OCZ PC-3700 Gold Rev. 2.0 .

OCZ PC-3700 Gold Rev. 2.0 comes with ProMOS chips that perform similar to high-clocking CH-5 memory. For the Gold Rev 2, OCZ has binned their chips to make sure you get the top performers (PC-3700 Gold Rev 2 is OCZ's highest speed w/ ProMOS chips, if I am not mistaken). These offer 240-250MHz w/ mid-grade timings (2.5-3-3) - still a trade-off from tighter timings but a lesser evil. It's not too cheap though.

That PC-3700 you have listed does not have any chance of coming with Winbond BH-5 chips.

I figured that much. I have little hope of getting any BH-5. Im just very interested in getting 250+ on the bus.

My NF7 for some odd reason wont run stable with any multiplier over 10x. Thats the core reason why I want a much faster bus.

Besides Im only using Level One right now anyway and my CH-5 is capping out @ 225.

However I want something that is gaurnteed to run 500mgz tho. I like the Idea of using 3700 but am hesitant to do so in case it wont run 500mgz.

If I can get 500mgz reguardless of timings, I may yet get 2.4 ghz. Without a high bus speed im screwed @ 2.25

....Im still leaning more towards the Geil simply cuz its rated at that speed plus its cheaper!
