i am currently having problems when running windows app's. periodically my screen keeps cutting out (going blank) then coming back on again... very annoying! as far as i can tell its not a monitor problem as the power to the monitor does not cut out. i am thinking it is either an overclock problem or something wrong with the new memory i have just installed: my 2.4ghz celeron d 320 is currently running at 2.6ghz, not a massive increase (stock cooling), though am thinking that the fsb increase may be causing problems with the memory or pci frequency (though i could be totally wrong, dont know a lot about this stuff!) either that or the new memory i just installed (512mb corsair PC3200) may be conflicting with my old 512mb micron pc2700. i thought that the two different memory types would run together, is this not right? any pointers to the cause of this problem (and even better how to fix it!) would be much appreciated! cheers.
what cpu nd system temps r u getting. i dont think that u can run 2 different memory types perfectly at the same time coz u shud have memory of da same speed.
Try with the old set of RAM and see if the problem occurs, then swap them over and try the new RAM, also check in your BIOS and make sure that the PCI/AGP settings are locked so that when you overclock they stay the same, they are very sensitive to speed increases.
processors running at about 50 degrees c at idle, mainboard at about 40. stress tests only took it to about 65-70ish, though didnt run it for that long. i reckoned it was probably the memory conflict, as i overclocked before i installed the new memory and i dont remember it happening before then, though was hoping that it wasnt! do you know of any way i can make them run together better? will they both be running at the same timings or will i have to change my bios settings to get them both running the same way? again, i'm not too sure what i'm talking about, still learning, so any help/explanations would be appreciated!
It's possible that the timings have been tightened on one set of RAM to match the other, this can cause instability, go into the BIOS and look for something like "Frequency Options" or something like that, that should contain information and settings on the clock speeds and timings of things. Loosen the timings of the RAM and you should be set.
There's a couple of programs that can be very helpful in testing your OC'd settings. [google]Memtest[/google] which you can see if you're getting memory errors, and [google]Prime95[/google] for hammering the CPU.
Hi, cheers everyone for the suggestions. Tried loosening the timings on the memory, but no joy, still does it. Also ran memtest for a few hours and didn't show up any errors. So I set my processor clock speed down to what it should be and it seems to have fixed it. So am thinking it is the PCI/AGP frequencies, though can't work out how to lock them. Does anyone know what setting I need to change in BIOS that would lock them so I can get my processor clock speed back up again?! Have tried changing a few options but nothing yet... (My BIOS is Pheonix Technologies Version 6.00PG) Cheers.
That depends on what chipset your motherboard has. If it doesn't have the i865 or i875 and i9xx chipsets (or if you happen to be running an nForce 4 SLI Intel Edition-based board), you don't have the ability to lock the PCI/AGP/PCIe bus. I also caught the 60-70*C under load. Basically, the general rule of thumb is that 60*C and up is considered the danger zone, so if you want to overclock, you'd best invest in a little better cooling besides stock.
