9600GT GDDR3 Timings

[iDont]

Hello,
Recently I came across Solaris17 his 8500/8600/GT/GTS Mod Guide and noticed the timing sets part in the thread. Now I've flashed my graphic card aswell, but I never really looked into the memory timings, so I decided to check what alternative timing sets Nibitor provided me with.

I found timing set 4 to be the fastest, but those timings are a lot tighter than my default ones. I've OC'd the graphic memory from 900MHz to 1050MHz (memory modules are rated 1000MHz), unfortunately at 1080MHz the card started to artifact.

As the difference between stable, tested with atitool + furmark, and unstable is just 30MHz, how would the tighter timings affect the stability? Is there any way to test the timing set instead of just blindly select it and flash my graphic card (I know, not smart)? In Solaris17 his guide he basicly just tells to select the timings and flash, I don't get that.

I've got no experience with GDDR timings yet, but I want to get the most out of my card (I thought about Vmodding aswell, but I got a 9600gt with the tight OCP protection, any suggestions on this are welcome aswell)

Thanks in advance,
-iDont

edit:
It's an Asus EN9600GT HTDI, the memory is air cooled yet stays cool. It's flashed to 750/1925/1025 (core/shaders/mem) clocks.

how about lossen the timings? I think its better if we can OC more on clock speed rather than tight timings could someone confirm this?

In desktop memory tighter timings are always better, and I'd sooner take 800MHz @ 4-4-4-12 than 1066MHz @ 5-5-5-15 as less latency is far better in my opinion.

Try and find the perfect balance between Mem Clock and Timings, it will help you a lot.

Finally, if you know nothing (and I'm not saying you do!), leave it alone as you will only mess things up when you fail to do something right lol

Yes, this seems rather logic, but my video mem timings are already loose imo. I don't think loosing the timings further would be smart performance wise, even if the clock speed can be cranked up a bit then.

And that's what I would like to do, but isn't there another way to test stablity with new timings other than modify the BIOS and reflash my card? That seems to be a rather long and dangerous way (well, I can always reflash blindly if the card wouldn't work properly anymore, but that isn't the best way either, is it?)

Thanks for your responses,

My advice to you my friend is to PM Solaris, as he seems to know what hes going on about where as I'm just a n00b when it comes to this kind of stuff lol

I'm sure he will help you

Thanks, I'll give him a PM

Well , if i were u i'd go for 1066 @ 5,5,5,15 over 800 @ 4,4,4,12 .. try it and u'll know why ..
