New Ram?

I have two 2GB sticks of DDR2 800MHz RAM. Lately my PC hasn't been able to boot up when I set the RAM to 900MHz, when in the past there were no problems. So I decided to test each stick individually at 900 MHz. Stick 1 booted up properly. I moved on to stick 2 which at first did not boot up, I tried it in multiple slots and still nothing. I thought I had found my problem BUT i tried stick 2 again just to be sure, and what do you know it decides its going to boot up now. Now I have both sticks in running at 900MHz, but I'm sure ill get the BSOD/restart that I have been getting recently. My question is, do you think I should go ahead and buy new RAM?
 
Well run Memtest firstly.

Have you tried upping the memory voltage by .1? Could be the issue.
I have had 5 hour prime stable overclocks that magically screw up 1-2 weeks down the road and become unstable within 10 mins of the test.

Worst case you gotta buy more ram. I would advise you go a head and get the 1066...personally I laugh at overclocking ram...not a noticeable difference doing it for me.

Well I would get the 1066, but my mobo only supports 800 :(
 
You can try upping the voltage by .1v as suggested earlier.

Does your system work if you back it down to stock settings? If so then it's highly likely that your overclock isn't quite right.

As far as I know it works fine at stock speeds, I haven't gotten a BSOD yet. But it seems to be more unstable when the RAM is linked, thus going up to 900MHz. However when I leave it unlinked it seems like my CPU is being bottle necked, that's what my SuperPI score indicated however.

Why does linking it automatically mean it's 900MHz? Dual channel DDR-800 should be more than fast enough for a Core 2.

When the ratio is set to automatic it goes up to 900MHz, when the FSB is set to 1200. It boots fine when I keep the RAM unlinked, but it seems like that is worse than stock speeds.
 
Oh ok I understand what's going on now. You're leaving your FSB overclocked and setting the RAM ratio to the preprogrammed SPD settings which causes it to be overclocked. I meant does your system run fine with 0 overclocking on anything.

Since it is working at stock your overclock isn't 100% stable. What RAM are you using? I see that it's corsair but corsair makes a lot of different DDR2-800 sets. Also what settings are you running it at (timings and voltage)

Everything is at stock, 5-5-5-18, 1.9v.
 
Alright, I'm on a different PC right now but I'll try that along with running memtest. If I do see any errors with memtest is that be enough evidence that I have faulty RAM?

Thanks for all the help btw.
 
Usually if you see no errors on memtest then you are good. If you get errors while overlcock but non while running stock then that doesn't mean you have faulty RAM. If you get errors at stock then it's very likely that you have faulty RAM, there's a chance that the fault is else where but it's usually the RAM at that point.
