my new build is Asus P6T v2 mb, i7 975 cpu, mushkin redline 6 7 6 18 memoryWhen I run CPU-Z my memory timings show as 9 9 9 24.My question is do I change them in the bios to the 6 7 8 18 memory right away orgradually change them.I want to overclock, but this is my first build and I'm new to this.I tried searching the internet, but couldn't come up with any clear instuctions on overclocking.ThanksArnold

Hi Arnold,I have just done my first OC, although I have been building PC's now for 10 years.On the RAM OC- before you touch anything, just be aware of the fact that there will be two limiters to being able to tighten those timings- the first is the RAM itself, what is the tightest timing set for the clock that you are feeding it. I'm not sure if you are running synchronous, or how you have configured your NB- if you are either upclocking or downclocking the RAM then you need to factor that into the what the RAM is seeing. Secondly, the voltage that you have set the RAM to. In my older (than your's) GA board, the voltage setting for the RAM goes in steps of +.05V. When I asked the question I was told that usually the default voltage is 1.8V, so since I have mine set in BIOS to +1.5V, that's 1.95V, which is the highest that the manuafacturer guarentees the RAM. Having done this before recently, if you don't understand any of this then you need to go back to the books and research these topics, particualrly the manufacturer's site and there are also many good articles on OC RAM on the 'net. And mayube someone here can help too, I know just enought to be dangerous :)Having said all that, it seems that you have yet to try overclocking at all- and if that is the case then all of the above may not matter since it factors into how the RAM will behave when you raise the clock. My short answer, for what it is worth, is to start setting the RAM timings on manual and gradually tighten them up, re-booting after each timing change. On my board, if I go too far with timings or clock speed, the BIOS resets itself to auto modes and will result in something similar to what you have now (if you have not yet OC'd).Secondly- if you're like me and a little intimidated by all of this, there is an app called MemSet (free I think) that will let you change RAM settings (timings) while in windows, and as long as you don't press "save" they are not saved in BIOS, so if the whole thing locks up then you can just re-boot to where you are now.I don;t know if these failsafe features factor into having too high a voltage though, so I would be careful with the volts if you need to raise them. When you hit a spot where the RAM won't work at the timings you have set, chances are that you will need to increaes the volts- or you have driven the RAM beyond what it can do.Good luck- there are many here that know much more than I, so you may get some better advice too :)Bruce.

Oh no - don't set the DRAM voltage any higher than 1.66 in BIOS :( The tripple channel DDR3 memory sticks used on Core i7 X58 motherboards should be run at 1.65V. On my P6T Deluxe (version 1) the DRAM Bus Voltage is set to 1.66 (can't set to 1.65 - odd!).Here is an article on OCing a 920: http://www.bit-tech.net/hardware/cpus/2008...l-core-i7-920/1There are several posts on OCing i7 here on avsim hardware forum. Just do some search.Use OCCT to test your OC stability. Core temps should never exceed 80C.There is differences between processors coming from different production batches. No one can say exactly what voltages and timings your setup needs to run at specific frequency. It's a time consuming process to get a stable OC at the lowest possible voltages.Some general guides (NOT FOR Core i7): http://www.xbitlabs.com/articles/cpu/displ...e-oc-guide.htmlhttp://www.xbitlabs.com/articles/cpu/display/oc-guide.html

Oh no - don't set the DRAM voltage any higher than 1.66 in BIOS :( .........

Thanks Ulf- I was referring to my older Q6600, looks like I really CAN be dangerous!Bruce.

No problem. Proves we are human and why checklists are important :(

I want to thank you for your help.My memory timings are now set the way they should be at 6 7 6 18.My next task will be to do a little overclocking when I get a little moreknowledge and some nerve.Thanks again for the helpArnold
