Overclocking, what's more important


Recommended Posts

Having the highest 1:1 CPU: RAM timings as possible, or having the highest A-synch timings you can achieve.


Currently running the below set up at 222Mhz (RAM timings - 2.5-3-3-6 @2.7v) without errors, but do I relax RAM timings more to get higher synch (1:1) overclock or do I go a-synch and change the CPU:RAM divider?

So, I'd be better off with my RAM timings at 2-3-3-5 with a 5:4 divider (RAM @ 200Mhz) and cpu at 250Mhz which would get me a cpu overclock of 2250Mhz (450mhz over stock).


My XMS was stable at 210mhz (1:1) with the above timings, so I may be able to get the cpu a little higher.


Thanks, I know what I can work towards now!

I don't mean to steal this thread, but I've got another poser for everyone here...


What's more important for overall overclocked system performance...


10x multi, or having 512k over 128k of L2 chache

I'd say the 10x multi, at least with the Sempron! The cache doesn't seem to matter as much to me.


Do you have that rig up and running, Rustafur, or are those parts on order? With the 2800+, the default multi is 8, so you'll need to run high HTT for speed! (The Sempys can do it though!)

I gotta wait until payday until I can order it up, which will be next friday. Just in time for me to get sent to spain for two weeks... ugh. And I've changed my mind on the proc, I'm pretty sure I'm going to go for the 3000, or 3300 to take advantage of the higher muti's. But those 90nm's can sure crank up the HTT can't they?

Yeah, they sure can! Good move going for the higher multis - your ram will love you for it!


Now that I've got my VX running the way it should, I'm going to see how much more I can get out of this 2800! I've had it up to 2.6 foolin' around, but it wasn't stable with the settings I was using.


So, now I'm taking it slow and doing it the right way!

Oh wow, 2.6? I'm just shooting for 2.4 for my build, as this is my first OC'd rig. So you can bet I'll have a build journal on here with new questions every day.


...and to keep on topic in this conversation, well sort of.


I am planning on upgrading to 2GB of memory soon, will this have a grave effect on my HTT, even with memory dividers in place? I don't see how it would, but hey I'm a newb at OC'ing.

Ok, running 2.5-3-3-6 RAM Timings at 205Mhz. CPU is at 2257Mhz (9*250Mhz) at 1.36v.


Just Ran 3D Mark 2005 and got a score of 3839.


That any good?


In the second pass of the gaming video, the playback was SO choppy. Is that normal? I've never run 3D Mark before and didn't know what to expect. But when i saw how choppy it was I began to sweat.


Here are the result out of the 3D Mark 2005;
