OC'ing RAM?

I just bought 2 sticks of Kingston Value RAM (PC2100 256MB) from OfficeMax (9.99 each after rebate) and put them in my secondary.

I OC'd them to 166MHz, still running in dual channel mode, timings 6-6-2.5 or some such.

I upped the VRAM to 2.7.

What do you think this RAM can do, and how should I set it up to do it? I've never OC'd RAM before, nor have I changed the timings or latency settings ever. What should I try?

Also, I'll be putting 2 sticks of 512MB PC2700 Samsung RAM in my Primary, but I'd like to OC it to 200MHz, to match my FSB speed... do you think this is possible?

    Possible? Yeah, sure.
    Probable? No.

    Try it anyway.

    I hope your talking about that kingston and not the samsung. That PC2700 should go to 400 without any problems. The Kingston will be lucky to go any higher. But what do I know, I use Crucial.

    Yeah, I'm not trying to get the Kingston any higher. I'm surprised it can do 166... but it did with no hiccups... hrm.

    I'm just hoping now that the Samsung really can do PC3200 speeds with the same lack of error.

    For your primary rig just try easing it up @ default timings. Then if you need to back them off or add voltage along the way do so and keep trying. Then try to back down on the timings a little at least the cas once at 200 if you make it, which I think you have a decent chance. As far as the Kingston I think you are about at its limit although you can always try for more. To test either one just run loops of prime and 3D Mark at the same time for at least a few hours, preferably overnight (generally it doesn't take long). Since I take it you will be folding with these I would go for 24 hrs of testing to be sure. You should also bench your memory at the lower speed w/ tigher timings vs. higher speed w/ looser timings to compare. Generally the the tighter settings (especially with AMD systems) are preferred. This is why a bunch of us have been pushing for people to try to stick with the better quality memory. So that they can run it as fast as possible and still keep tight settings.

    Testing is important. Some times relaxing the timings a little doesn't hurt perfomance and lets make the speed.
    You need benchmarks to tell you this. Some people like running the Sandra memory tests with all buffering turned off. This is a good 'raw' number.
