i looked up the samsung 1.1ns memory we have on our x1900's according to samsungs website its supposed to run 900mz, this got me thinking. After some poking around i found this

Yes, I know that the memory is rated for 900mhz, but it makes more sense to run it at lower frequencies with tighter memory timings.

Since when does overclocking your vram loosen its timings? as far as im concerned it just increases speed.

Using the program Overclocker it actually lowers your ram timings to allow for a larger overclock of the ram. ATI tool keeps the aggressive timings, which turns out to be slightly faster then running the ram at 900mhz with loose timings. This is old news, when the x1900 series first came out this was all discovered, it is common knowledge.

Ah. I dont go near ATi's. There completely foreign to me, lol. And i generally use the term 'loosen' timings as lower givs the idea of lowering the number (tightening timings)

PS. thats a bada$$ rig you got there

When you hear a member say "loosen" refering to memory it means increasing the cas/ras/tras latencey. So for example if your ram is at 2-2-2-5 and you want to loosen your timings you might try 3-3-3-7.

Thanks

Well then, he can try Radlinker or ATI tool then.

no overclocker DOES NOT loosen the timings, the CCC enter does.

So you'll also need to download a little program named simply Overclocker.

I'm sure about now some of you are saying "Why don't you just use Overdrive since it's built into the Catalyst drivers?" The answer is overdrive will limit the amount of overclocking that can be done. It also has been reported that it will loosen up memory timings as the clocks get higher, which means less performance as you turn up the MHz.

There are several threads at the XS forums on this topic. OC you card with overclocker to 900mhz and benchmark. Then use ATI tool to overclock your card to 840-850mhz and see the difference in scores.
