  1. I use custom torture test and set it to 800mb per prime95. ends up u sing just over 1.6gb of 2.0gb ram and I don't page at all.
  2. Precisely which error are you getting in prime95? If it's the error reading temp file one, you might not have prime95 configured properly.

    Opty 170 memory controller shot?

    Get support on the ram before you send it back. A BIOS setting being wrong can make good ram seem bad. Also, running dual channel (with more chips) does put more stress on the mem controller - so even with perfectly good ram, what you overclock to on a single stick may not be the same as what you OC to on two sticks.
  4. Your sig has: 2xOCZ DDR Platinum Rev2 1GB PC3200. Do you mean 2x512mb = 1GB? Because they didn't make rev2 Platinum as 2x1GB. This means you can expect your ram to run somewhere around 206mhz at cas 2-3-2-5 1T or 220-230mhz at cas 2.5. It runs at great timings, it just won't go very high on raw speed.

    Vcore discrepency?

  6. Not sure what auto sets them to, increase them to get more clocking headroom. As your HTT gets high, you may have to raise them. For me, at 300 HTT I had to set them to 9 and 6.5. or 9 & 7.
  7. Try 9 and 6 , 9 and 6.5 or 9 and 7.

    You can find out which by dropping your cpu mult a step and testing again. If it succeeds this time it's likely not your RAM - though RAM timings *DO* impact CPU mem controller stress. Have you tried increasing max async latency and read preamble? Try 9 and 6.5 or 9 and 7.

    Need HELP with OC settings

    It's not just temperature that kills your CPU, voltage can kill it too. Many feel that when you start getting too much over 1.6 and run it 24x7, you will shorten your CPU's life quite a bit. Also, I wouldn't really trust the temps on the expert board. Many have reportred them to be 10-15c under. I honestly couldn't say what to expect at 1.75v as I haven't seen anyone post that they run that many volts through their chip. Voltage is certainly a comfort factor - I just wouldn't do it with my chip. In fact, I'm running 2.67ghz 24x7 because I can do it at 1.475v.

    The odd thing is, I heard that you only had to increase async latency when you weren't running 1:1 and your HTT got high. I wonder if your case proves that wrong and it's the read preamble that helped, or if MAL had to be increased to get it to run right. Mind testing it out and letting us know?
  11. What are your max async latency and read preamble?
  12. What is your max async latency and read preamble? Increasing those might get you further on less voltage. I had to increase mine around 300 HTT. Try 9/6.5 or 9/7.
  13. Good call on switching to prime. For a dual core chip, don't bother with memtest except to validate your ram runs legit at stock speeds (always good to make sure your default system is stable). My experience is that I could pass memtest at a much much higher speed on both RAM and CPU than I could pass dual prime95.

    DFI nf3 Ultra D Overclocking?

    CPUz is not accurate, what have you set your voltage to in BIOS?

    Need HELP with OC settings

    with your RAM at 1:1 and your cpu multiplier at x9 or x10, what is the maximum you can get your HTT/FSB? (Start at 200 and gradually increase it) That's how to find your max RAM speed. With your RAM, I found max RAM = 206mhz when using prime95 at cas 2-3-2-5 1T and somewhere between 220-230 at cas 2.5. Also, be sure when you find your max speeds of both RAM and CPU that you use prime95 to validate that it is stable. For example, with your RAM at 100mhz divider and your cpu at 2976mhz, can you run prime95 stable for 8 hours? EDIT: and to answer your question, often times you have to back down slightly on CPU as you increase your RAM speeds. Or another option is to increase voltage a bit as you increase RAM speeds. Faster ram puts more stress on your mem controller (which is part of the CPU) And EEK, you don't want to run at 1.75v!!!
