Hi, I have 2 x 512 of PC4000 Ballistix CL2.5 (BL6464Z505) and my problem is that on first boot from cold I can run 265 x 9.0 (2.385 Ghz) and it will MemTest with no errors for about 4 passes.
Then the errors start to appear, 2 or so per pass. If I leave it running overnight I then get over 1000 errors per pass. To get the setup stable I then have to drop down to 200 x 9.0 and still get the occasional error.
But if I switch off and leave it, when I switch back on, I can then boot it up again at 265 with no errors.
To get a continual run of MemTest with no errors overnight I have to use the "Optimal Settings" in the Bios.
Have tried lots of different settings and any thing above 200 x 9.0 will eventually start to give errors.
I now feel from other posts that there is some incompatability issues with this Ram and the nF4 boards?

That is not at all uncommon for memory to warm and 'begin' to error and is why most of us know that a couple of passes of memtest is NOT enough. I seldom accept any findings of Memtest86 V1.51> until after 15 passes or so and then I take a look at the results being given.
@ "large" users. I see a number saying that trying my settings has had little results for them with Ballistix and I am not infallible. When writing up my "a little help to get going" post I had run the Ballistix and thought that the settigngs I was using were alright on it TOO, but perhaps I was wrong. NOW hear THIS, I do not consider overclocking until I reach about 250FSB or have a 1800mhz processor running at 2450mhz. That leaves out me testing much of a whole lot of territory some of you guys overclock IN. So for 'me' and most ANY type of memory> one should have the Cas Lantecy at 2.5 anyway by the time they reach 240FSB or so. I am quite sure that even PC4000 Ballistix is at Cas2.5 by 250FSB and loosening the other timings at that speed are just about a given. Anyway I did run some more tests using my 3200 Ballistix and MaxAsynchLatency can be left to AUTO and ReadPreamble can be set to AUTO as well and it seems fine on my board *depending* on which *processor of 3 that I run. Ballistix is extremely finicky about which processor I use. That leads [email protected] me to believe that the Ballistix is dependent and highly so on the memory controller built into the processor.
So far that is all I have seen that because I have "actually" seen it with my eyes and not someone else's, I feel is correct to report.
EDIT: I may have better results to some extent because I know the stuff runs hot at the 3.0Volts I have to run it at and I have a FAN blowing on my Ballistix when in use. END EDIT.
