Hi all,
I have just been testing my new/replacement Ballistix PC3200 1GB kit (2x512) and am fairly suprised at how much they overclock?
I wonder what these chips are? It should say *Crucial* in the manufacturer tab but instead says 7F7F7F7F7F9BFFFF (?)
I only found this out because I am trying to overclock my new Opteron and for some reason these sticks don't let me use dividers. My normal practice when I test a new CPU is to lower the frequency of the memory with a 5:4 divider and start whacking up the FSB/HTT, but for some reason these sticks were not letting my PC boots properly while doing this. At first I thought my CPU was a dog but after some headscratching I thought sod it, just put the memory back to 1:1 ratio and overclock it all at the same time.
As my old sticks of Ballistix PC3200 were able to run @250MHz with loose timings I thought that would be a good place to start, so I went into BIOS and slackened the memory, put the vDimm to 2.8v and started.
To my delight it booted fine and passed many hours of memtest and prime95, so then I did the same @260MHz no problems, 270MHz fine, but when I tried 280MHz I started getting the odd error in memtest. I tried adding more voltage to the Memory, CPU, Chipset and HTT but no joy.
There are a few more memory timings that I can change in BIOS but I am new to the A64 platform so I am not sure whats what?
Here is a screeny from A64 tweaker, which I dont know how to use but it lets me show you memory gurus my settings:
I want to try and *loosen* the memory but I am not sure what to change, maybe Trcd from 4 to 5 and Trrd from 4 to 5.
What sort of overclocks have you guys been getting from your PC3200 (and PC4000).
