More of a heads up really, I was running at 3.15ghz (450 x 7) with memory at 5-5-5-16 (see sig below) and I decided to drop me overclock to 2.8ghz (400 x 7) with memory at 4-4-4-12. Superpi now runs 1meg at 20secs whereas before it would do it at 18secs
BUT, overall performance (gaming framerate, etc) APPEARS to be the same. obviously the tighter ram timimgs help. I always assumed that conroe based systems liked high fsb, as opposed to lower fsb with tighter timings (aka amd prozzies). Like I said, just a heads up really, so if you can't get above 400mhz with an e6300, it doesn't really matter a lot unless you can get to around about 475mhz i would think.
wadya reckon?

yeah i also through the core architecture wasn't as latency sensitive as K8, guess theres a little bit in there though, nice find :)
 
Well like I said, superpi takes longer, but overall performance appears to be the same. I've read somewhere here about this DS3 strap thingy losening timings but didn't pay too much heed, just wanted the highest fsb. seems to make difference. I hasten to add I haven't done much benching to compare, just what I find when running fraps ingame and doing the odd performance check aka in "fear and coh",

And yes, the e6300 multi is 7.
 
Try this:

Go back to your previous overclocked settings and bench SuperPI.

Then, reboot. Keep volts and memory as close to the overclocked settings you ran above. Keep the FSB at 400 and boot so that it doesn't losen your strap. Then use clockgen software to raise the FSB back to your original clock. Make sure you're giving your memory enough volts and at right timings so that when the memory raises itself with the FSB, it will still be stable.

Result should be overclocked settings at tighter strap. Stability is another thing though. I think you should be safe for a fair bit of FSB above 400 at the tighter strap.

I'm now currently at 2.975ghz, nearly 3ghz, (425 x 7) with timings at 4-4-4-12 with only the ram at 0.3vdimm, everything else at stock.
Just ran superpi and knocked a second off me result, now get 19secs :)
I'm more than likely in, or around the point of this strap loosening the chipset timings?
I'll see how it goes with tese settings but it looks like I'll keep them for a while if stable
 
Which games are you playing that you would notice a difference in anyway.
I once accidently halved my cpu speed and didnt notice for a few hours till loads of vehicles were on screen and it slowed down way too much.
 
You need to lift your FSB just a little higher - 457-460 FSB I think to get the benefit of being over 425 FSB with the looser strap.

Only tried two games, farCry is showing up to 100-150 fps depending whats on the screen, and COH with max population. All games settings totally maxed out. It appears fraps doesn't work too well with COH (for me anyway), but the overall "feel" of the games is that they're running the same as they were with the higher overclock.
I also ran "03" and "05" and the scores were a bit lower (can't remember exactly what they were, it was very early in the morning (check post times :p ), but there wasn't as much in it as I thought there would be. I tend to ignore benching as I only use it to see if the pc is running right and all the hardware/software is working properly, an increase or decrease of say 500/750 marks doesn't really bother me, as long as its "in the ballpark" as it were. As long as its stable and the temps are fine, then I'm happy. :)
I'll not bother overclocking the fsb for a while as I'm happy with the performance as it is with these settings, and I've taken 1 degreeC off me idle temps :p.
 
you wont see ANY difference anyways in games, most games are GPU limited, my AMD opteron 2.8ghz with 7900gtx runs company of heroes within 1fps or exactly the same as a core2 at 3.5ghz with 7900gtx, same game, (any res above 1024x768 with all the settings on max, on any modern-ish game will produce similar results, same with 8800 cards or any ATI card)

You will achieve higher benchmarks obviously with core2 and higher 3dmarks, that's about it ;)

When games start using CPU's better core 2 will also achieve better performance

Obviously many on here will tell you it 'feels' faster, probably does, however average/max/min fps will be more or less same

As said above most games will be gpu limited, try running some older games such as HL2 and UT2004, those are known to be very cpu limited nowadays :)
 
So....then theres really no point in overclocking above a certain point unless you're into benching then, or get above a certain point that makes a difference to game performance?

Correct, obviously if your using software that gains advantages from faster CPU (database stuff, scientific software etc) then you will see good gains, however you would also then want stability so overclocking to far would be a bad idea. All about balance
 
Its not that its pointless as a whole, it is with games to an extent, but other programs its handy. The overclock I have on my server turns it from a good rendering machine in 3dsmax to a very nice one indeed :)

And don't forget about extending your ePenis!
 
It helps a lot with video encoding and I think it improves general machine performance/feel. Also it extends the life of the system, I dont upgrade that often so if I can double the power thats twice the use I get for my money in the end.

Strategy games use lots of AI I think so it helps there, age of empires?
I heard about people running games with 50+ AI players on BF2 using their overclocked cpu, normally impossible to do.

I hope we'll see physics in games that can be altered according to cpu or add on card power, that'd be a good use. Iam not sure how well it works in multiplayer games though, it was a problem in CSS beta testing I remember.
 
All the above posts have good relevance here but it appears to me (has done for some time actually) that the effort in trying for that last 50mhz overclock isn't needed it seems to me. I like an "easy" overclock that gives a nice boost for free without having to spend hours trying to get that little bit more.
That doesn't mean I don't appreciate all the hardcore clockers here that get their prozzies to scream in pain 'cos they're running so fast, makes life interesting doesn't it.
My e6300 went up to 400mhz fsb without any effort or voltage increase (except for the memory) and realistically has saved me hundreds of pounds 'cos its now running faster than an e6600 at stock, now thats worthwhile to me :)
