a5ian300zx Posted August 27, 2009 Posted August 27, 2009 (edited) Hi, i have been trying to OC my motherboard for ages now and for some reason cannot over clock it more than 3.2Ghz on Water it just does not boot and TFT goes into sleep mode, I recently bought 4gb corsair ram TW3X4G1600C9DHX as one of the guys on asus forum got it to run on really tight timing which is what i wanted to do, he posted his setting but for some reason mine just does not boot. it display dec ram on the LCD display regardless of if i have 2gb or 4gb. please see below for his settings.

I used these settings 24/7 rock stable no bsod`s in vista ultimate x64 and windows 7 ultimate x64!!" now i want to run the ram on some tight timing but cannot get it running at 7-6-6-15 1T @ 1.8v, at the moment im running at 1600mhz but with standard timings of 9-9-9-24 2T. any help would be really appreciative, please see below for my spec.

Waco Posted August 27, 2009 Posted August 27, 2009 Change your command rate to 2T. The difference is next to nothing and it makes it MUCH easier to run high memory speeds. Share this post Link to post Share on other sites More sharing options...

a5ian300zx Posted August 27, 2009 Posted August 27, 2009 Change your command rate to 2T. The difference is next to nothing and it makes it MUCH easier to run high memory speeds. i have already tried that but still the same issue, Also change this to normal! I will try this and see if it make a difference. If this is your memory, I would say you have your timings set to tight! my memory is running at 9-9-9-24 2T - but i want to get it tighter so its quicker thanks Share this post Link to post Share on other sites More sharing options...
AIinc Posted August 27, 2009 Posted August 27, 2009 Well, you can either overclock, and run the normal timings, or run the CPU at stock speed, and try to tighten the memory timings. Not both. Sorry! In actuality, you will not even notice any performance gains by tightening your timings. Only in benchmarking, and even then, not much of a gain.

Only in benchmarking, and even then, not much of a gain. then i don't understand how that guy is running the same CPu/memory/motherboard as me at 3.8ghz on air with 4gb xms3 at 1600Mhz 7-6-6-15 1T @ 1.8v. when i can't get pass 3.2ghz on water (highend) at 1600mhz. I ideally i would like to increase my cpu and FSB speed and with the tight timing it would have been really quick. there also a guy who left a review for this ram on ocuk shop say he was running the following: Reviewed by: extremeGamer I am using this super UBER FAST ddr3 on my maximus extreme at 7-6-6-10 1T timings @ 1.8volts! with these ULTRA TIGHT timings I even outperformed the same ddr3 1600mhz expensive dhx kit which is rated at 7-7-7-20 for the price of Edited August 27, 2009 by a5ian300zx Share this post Link to post Share on other sites More sharing options...

AIinc Posted August 27, 2009 Posted August 27, 2009 Thats it! What Waco said. This is true for most hardware! CPU's, Video cards, Memory...... Share this post Link to post Share on other sites More sharing options...
a5ian300zx Posted August 27, 2009 Posted August 27, 2009 Thats it!What Waco said. This is true for most hardware! CPU's, Video cards, Memory...... this is the bit that confuses me why would that be? I have the same models etc why is his better, im i missing something? should i buy a different motherboard to achieve the result or willi come across the same issue? thanks for your prompt feedback guys loving this forum already Share this post Link to post Share on other sites More sharing options...
AIinc Posted August 27, 2009 Posted August 27, 2009 I'm really not quite sure how to explain this better than it's already been said? 2 computer with exactly the same hardware, can & will (most likely) perform differently! Even though, you buy 1 set of memory thats XXXX+1234, Then you go back to the same exact place and buy another set of memory thats XXXX+1234 chances are that one set will out perform the other. Still to this day, mistakes are made. This is what bining is for, and even with testing, and bining, even though some chips are close, they may get binned together, but are still slightly different! You will find this in all aspects of computer parts! I built 2 systems, Identical to the one I am currently using. With the exception of the cpu, the other 2 were Q9650's One of the system's took more vcore voltage to achieve a stable 3.8GHz overclock, but at the same time, that cpu (in benchmarking), achieved higher scores. The other exact same system took less vcore voltage, to achieve a stable 3.8GHz overclock, but scored lower on the exact same benchmarks. There are slight differences in everything. Hope this helps a bit! Share this post Link to post Share on other sites More sharing options...

rourkchris Posted August 27, 2009 Posted August 27, 2009 You can't just plug someone else's settings in and expect your system, even if identical, to work. It would be so easy if you could just punch in the settings to go faster but it's not. There's too many variables from chip to chip and there's more of an "art" to it than the way you've gone about things. When things go wrong what are you going to do? Will you understand the settings you've changed? Overclocking blindly will leave you in the dark with a PC that doesn't work. Share this post Link to post Share on other sites More sharing options...
