Well I've decided that I don't really need a massive OC on my CPU (which requires large volts to do so), so I thought I might as well play around with my RAM, which is pretty good quality stuff.

The highest I've taken it to stably was about 975 MHz, on 1.95 volts. I thought that was pretty good, but with my current CPU OC I don't think they'll go that high (or too high) on the FSB.
Anyway, I thought of playing around with the timings. Set them to 4-4-4-12 instead of 5-5-5-15, 1.93 volts, 833 MHz, and WOW, massive boost! Everything loads much faster, and its all noticeable. I've always heard that speed is more important that timings, but now I'm really not so sure.

So here's my question; should I continue working on lowering my timings, or do I set them back to normal and try for higher speed? I'm loving the speed increase from lower timings, but would increased clock speed be better/safer/more effective?

If you can visually notice a difference from 5-5-5-15 to 4-4-4-12, then you must be a robot. The only reason to go high with memory speed is for the CPU OC. Usually tighter timings are better than higher memory speeds.

Either way, stick with whatever "feels" faster.

The only time I see a difference is in synthetic benchmarks or in-game FPS testing.

Odd...

Check out Tomshardware for a load of memory speed/timing testing on i7, C2Q, and PII setups.

Personally I prefer high clockspeed and slightly higher timings since that lowers the latency anyway which means it is overall faster. Try using everest's memory bench suite to compare the difference.

I would test it myself, but I'm not spending money on Everest. I might just leave it at these timings and see how high I can get the clock speeds to go.
And just from the tight timings, Vista loads a few seconds faster, programs load in about 2/3rds the time, and everything is more responsive!
Whats a safe voltage ceiling for my RAM? I have a 120mm fan pretty much pointed at it, and it has nice shiny blue heatsinks, but I don't want to fry it.

2.3v I believe for DDR2 maybe 2.5 if your batshit crazy.

Really depends on what chips your RAM is running...I have some Patriot Extreme Performance DDR2 with Micron D9 chips on them and I run them at 2.3 volts 24/7, but they will run 2.5v all day long...Best Ram I have ever owned.

D9 literally means "Micron DDR2". It tells absolutely nothing else about the chips. Micron has made dozens of different DDR2 chips during the years; D9DQT being really the only voltage tolerant type. D9GMH degrades with time and evetually dies even at 2.2V active cooled.

If yours are D9GMH or D9GKX (same chip diff. bin) I reckon you'll be buying new RAM sooner than later.

I myself go with higher speed with tightest possible timings.

Max safe voltage were described on your ram.if it is 2.1v,then dont be afraid to set it 2.1v.generally,2.3v with active cooling is safe,depending on the chips

I just had a look at my chips, the only stuff they had written on them are U83318C0AC8. Does this mean anything?

LOL... sometimes you can notice a difference with tighter timings, but in general speed is better than timings for intel chips.

LOL...I have been running these for almost 2 years now ----->http://www.neoseeker.com/Articles/Hardware/Reviews/patriot_pc2-8500/

Running 1066 with timings of 5/5/5/9 with 2.3v 24/7....This is their "rated" specs...as far as degrading over time....the Patriot Lifetime Warranty covers that. :p

Edit: and BTW, they have Micron D9GKX chips on them...
