Hey guys. About a month ago I upgraded from my dell box to a nice conroe setup you can see below in my sig. About the only thing I kept was the RAM and the 3 harddrives. The Audigy 2 wasn't originally from the dell anyway.

My system works very well, nice enough 3DM06 scores and good SuperPi times. Certainly much better then my P4 3Ghz and 9800Pro. But there does seem to be a problem with the memory. I'm not sure why this is happening as because of my overclock to 300FSB the memory is on an 8:5 divider and so is only running at 187mhz and I've manually set it's timings to its usual 200mhz level that it used on the dell. Theoretically it should be more stable or atleast that what I'd have thought.

I keep getting crashes in games like Med2: TW and X3 Reunion. It just freezes up solid with some god-awful screeching from the speakers until I have to reset. The funny thing is it will always about 5 minutes into the game stop responding and the sound will stop completely. However it only takes about 10 seconds to come back to life and after that it is fine until the bad crash that kills the computer.

Now I was having some trouble with my audigy 2 and this motherboard as well but I was pretty sure I had most of the problems fixed after a complete clean install. Oddly the onboard sound causes worse problems then the audigy 2 ever did.

When I run memtest in windows I get an error after anywhere between 5% and 25%

So there are several possible problems:

1: The RAM could be borked, damaged possibly in the install or from overclocking attempts or maybe it was already damaged and just somehow managed to run ok in the dell computer.

2: It's the motherboard that's the problem. It is pretty cheap and could be causing the errors in memtest.

3: The Audigy 2 is still giving me trouble with the board.


It just occurred to me that I could put the memory back into the dell and run memtest on that and see if that's the problem. I'm currently rebuilding the dell with parts that I can scrounge off people for my gf.
 
Ok it doesn't seem to be an actual physical problem with the memory but rather the timings that my Asrock DUAL-VSTA mobo set it to.

For my overclock to 300FSB I had to set the RAM to DDR333. The mobo then took the SPD timings off the memory for the standard DDR333 speed. It then overclocked the memory to 187 because of the 8:5 multiplier. I had tried manually setting the four main timings back to the standard 3.3.3.8 settings of the DDR400 SPD so it must have been either one of the other timings that I didn't manually increase or another issue with the overclock completely.

I have reduced the FSB to it's stock 266mhz speed and the RAM is at 190mhz at the DDR400 setting which is a 5:4 multiplier. Memtest passed 186% without any errors so right now the memory is stable. I am going to try upping the FSB to around 285 which will overclock the memory to 228mhz but if I remember rightly from when I first got the board that was actually stable enough.

So until I get better RAM I will have to live with a lower overclock then I had been using. Somehow I should have known that Hyundai Dell ram just wouldn't cut it :rolleyes:

Ah well, if it stops my games from crashing then I'll be happy. It's not like they were taxing my CPU as it was. When games come out that will tax it then I will have long since bought a DS4 or P5B and DDR2 RAM and overclocked my baby to 3Ghz :D
