Is it safe to run RAM at these settings?

post #1 of 4
Thread Starter 
Hi all,

I've got two quick question about what to set my system RAM to. I'm upgrading to DDR2 in acouple of weeks but here goes.

1) I currently have my CPU overclocked by raising the FSB to 220 and setting my PC3200 Corsair Value Select RAM to PC2700. I have done this as setting it at PC3200 makes it run at 444Mhz which is above it's verified speed (200Mhz x 2 DDR400). However I have had my rig running with it set to PC3200 today and not had any crashes or errors and everything seems stable. Is this a safe setting or should I not risk stressing my RAM and lower it's divider again?

2) As I said I'm getting DDR2 soon, the brand is Corsair Value Select again but it's PC5300 (667Mhz). Does this mean that I could raise the FSB on my new motherboard up to 240 without it stressing the RAM at all?

You can't use DDR2 with a motherboard designed for DDR. (same with cpu) As far as your first question, yes it's fine. 222mhz isn't that big of a push even for value ram. Performance ram can run 300 mhz or higher.

I thought so about my current DDR. As for the DDR2, I'm getting an nForce4 aswell (I know my current motherboard is 184-pin DDR and wouldn't take 240-Pin DDR2). I'm just guessing at the moment that the DDR2 667Mhz would manage an FSB jump to 240 without having to mess about with memory timings or dividers as it's rated FSB is 333.5. I say FSB 240 as from what I've seen on this and other forums thats about as high as people can go with the nForce4 but thats all I need to hit 4Ghz.

Meh DDR2 isnt really good for overclocking,yet, and that is Value RAM I doubt you will get a good oc with it.

And when it doubt of stability run memtest/prime95 and see if your system is stable.
