Said something about expected 0.5 but returned 0.4 or vice-versa. Not sure what this means...is it my memory failing to keep up with the CPU (which I am not really overclocking at the moment).
In my experience this error indicates the ram failing. To be honest with you, I dont think you will get much speed out of that Value ram and here is why, in order to increase the mhz, you will have to increase the ram timings. This will only work if it is in conjuction with the CPU speed. Here is what I mean by this, lets say you go from 2.5, 3, 3, 7 200 mhz to let say 3, 4, 4, 8 220mhz the speed is killed by the higher timings. Now there is a hugh difference by using "Good" ram (TCCD, or UTT variants) that same speed of 220 mhz and 2, 2, 2, 5 or even 2, 3, 3, 7 will smoke the doors off the stuff you have.
Now, an easy way to tell if it is your CPU or ram holding you up. As rdgrimes has mentioned, if you have the divider settings on your mb, just lower the ram speed by using this method and jack the mhz up on the processor. Here is a typical example,
set your fsb to 220mhz, now set your ram to 180 9:10 and your ram will run at 198mhz, 166 5:6 ram will run 183mhz and so on. These settings will allow you to test the cpu seperately from your ram. Once you find the max settings for your cpu then start to up the mhz on the ram by adjusting the divider on the ram. Remember to always stress test between settings.
I hope this helps.
