ddr 400 or 433?

I'm suprized that newegg doesn't have barely any ddr3500 ram. I just got an AMD Athlong 64 clawhammer 3500+ so I will be overclocking and I figured ddr400 just won't cut it right? I plan on upgrading my current 512MB to 1 gig, so pc3200 or 3500?

Look for some ram with TCCD or BH-5/CH-5 chips if your motherboard can do high voltages.

i would go with the 400 my self its a lil cheeper and still able to perform.

You dont NEED good ram to overclock your CPU. Just find the max speed your RAM can handle and run it on a divider. Your sig says "Memory - 512MB Corsair XMS DDR3500@400MHz (5, 2, 2, 2/2.7v)". That would probably work fine to get you a nice overclock. Just test to see what the limit of your CPU is and run your RAM on a divider so that everything will be running at its max. Heres a great guide...
