When is it enough speed?

post #1 of 9
Thread Starter 
At what point does computer speed become 'enough' because I may have hit the wall...

So I have my sig rig which you can all see and I overclocked it from 3.2GHz to over 4Ghz

I pushed the 1600MHz ram over 1840MHz

I changed from a mechanical drive to dual SSD in raid0

I have pushed the HT link or whatever it's called from 2GHz to 3GHz

My AMD overdrive benchmark score went from about 7,000 stock to around 10,500

I watercooled it, added cutsom heatsinks and I have 6 case fans blasting air through it.

I've got 2 graphics card ATI and Nvidia and i'm running 3 screens and the other day my rig did not boot due to overclocking (because im a noob at it) and it defaulted to stock.

Now the problem is... Going from the significant overclock to stock I didn't notice a decrease in performance at all. With that in mind I pose to you all the question. How much computer speed is enough?

Well .. you have never enogh speed! .. NEVER

But .. it seems you have pushed your system pretty far right now.

Good clocking though

This is Overclock.net! It's never enough!

Seriously though when you have a processor, you don't count speed by adding all the cores together. I'm talking about the 24GHZ comment.

I'm not a big AMB guy, but I'm pretty sure you should take your HT link down to 2000, unless you mean your NB is at 3000.

Well I know it's not conventional to count up all the cores but I think it may become more common with applications utilising more cores simultaneously. If I remember correctly Crysis 2 uses all 6 cores on my rig or at least I know unreal tournament does so totalling the cores makes sense in that situation does it not?

Yeah you're right I meant northbridge I kind of read guides and did it as a read and as a consequence don't remember which is which so well. as I think they differ in term between AMD and Intel? NB and FSB?

I'm not too sure on the terms but don't worry I'm 95% sure I overclocked the right one

But i'm just wondering now do I bother going back into bios and re-enabling my overclock because I can't get it 100% stable and I sometimes reset so is there a point? I can't notice a performance decrease unless I run a benchmark

this is funny, but it can happen

Your rig is clearly faster when OCed then when at stock speed. Weather you'll notice that or not, that's a whole different story. There are some limits to the human perception so that at some point you just can't tell the difference any more (for example 24Hz refresh rate for the eyes - one can notice double or a bit more, but not the difference between 120 and 200FPS/Hz; also some 0.2s average processing time from the optic nerve, around 0.4-0.5s a feedback eye-brain-hand for a conscious reaction - not a reflex). At some point you get below of what one can perceive at it doesn't matter any more if you can push the rig further or if the benches say it's faster.

It depends on the apps also. Some math heavy apps like matrix-like finite element computation will always use 5% more CPU clock speed, any OC is welcome. If I could push my work PC to 3.6GHz from 3.2 I would do it, and I would notice a computing time reduction of 5%. From 30mn, 5% is still significant. Benches are like that, they note these tiny changes because they push the rig to its limits like heavy simulations.

cheers

P.S. Besides, OCing is fun. It is also very rewarding on a low end PC. I know many folks that can't afford a 200$ CPU, so they just get a 50$ CPU which is very performance-limited. They just push it as far as they can and get to a reasonable performance level. Sempron/Duron(in its days)/Celeron/AthlonII are/were ideal CPUs for this.

Yeah I think I will re-enable the overclock soon as I intend to fold on my main rig rather than my laptop but I need to get it more stable and I don't know how...

Honestly? The only real way you could go faster is more SSD's to add to the array lol...

It's nice and fast right now

Hey buddy, I'd change the thing about the total GHz if I were you. Some people find it hilarious when someone doesn't know everything and they'll try to make you look stupid

You think I need more SSD's?

WEI (calm down just an example) tells me my HDD is the fastest part of my computer I would be thinking other things would be bottlenecking first.

OH! here is one thing I heard... I only have 2Gb of ram because I never use over 60% of it but does having 4Gb improve performance somehow? I have not gotten another 2 sticks due to the face that my motherboard likes it's overclocked ram in slots 3&4

Yeh cheers I took it out. Suprising amount of attention it grabs!
