Solve : Mixing Memory?

1.	Solve : Mixing Memory?
Answer» Hey everyone, I bought some new memory for my computer and made sure that the timings matched. The original memory in the computer was 5-5-5-18 but could run optimal at 4-4-4-12. The brand for that memory is Adata DDR2 800. The memory I bought is Crucial Ballistix DDR2 800 with timing of 4-4-4-12. So I went into BIOS and changed the speed to 4-4-4-12. Now they both match as far as timings go. Computer BIOS comes up, says 4gig 4-4-4-12 2T and Windows Vista starts to come up. Then, blue screen telling me that new added HARDWARE or software is the problem and should remove the newly added software or hardware. Any ideas? I've already tried every setting in the book. I got it to come up with a very high speed setting but will not run it that high. Plus it was very unstable. Thanks for the help. OK, went a little further with this. I upgraded the BIOS to the newest and it made no difference. I also decided to stagger the memory. Ballistix, the Adata. If I leave just to 2 in the computer runs FINE. When I put the other 2 in it blue screens and restarts. I take one out to leave just the 3gig and it Blue screens and restarts. I guess I should also mention that I had no problems running this memory in XP. Computer Specs E6750 (2) XFX 8500GT Professional Series 512meg Video running in SLI 2gig RAM Window Vista Business x64 OK, update. I tried one kind of memory in one slot and the other in a different slot. That ended up failing after about 15 minutes with a blue screen. Any ideas at this time would be great. Thanks. It's foolish to mess around with RAM timings especially with mis-matched RAM...you're only asking for trouble. Re-set to the default settings and ADD one stick at a time and see what happens...Ok, foolish is kind of harsh. I have already said that the memory is in specs with each other. There should be no reason they shouldn't WORK together. Now, can anyone give me a "good" reason why they may not work together? Thanks for the help.

Thanks for the help. A good reason is exactly what Patio was getting at. By changing the timings in your BIOS, you've tried to overclock the slower RAM. Overclocking RAM is quite an unstable thing to do, if you don't know exactly what you're doing, which by the sounds of it, you fall squarely into that category. Now, if it were me, and I'd been foolish and changed the latency settings of my RAM in my BIOS without knowing what I really was doing, I'd now do as he said, reset the memory settings to default and try the RAM sticks one at a time.Thanks for all the help guys. The funny part is I'm running the slower memory right now with the higher settings and it's running with no problems. That's why I don't understand when putting in the faster memory it doesn't work. As of right now I have tried one stick at a time and it didn't work. I tried different timings and as long as I leave one brand or the other in together it works fine. So that's where I'm at right now. Running the slower memory at a higher speed with no problems at all.
