    Exclamation OCZ Reaper Overclock

    Hey there Guys, im pretty new into overclocking, and benchmarking programs, Although i have read some guides and articles about it, always been a hardware freak and always built my systems for overcloking should i ever wish to dabble in it, but its not until now i actually really tried, and now im just craving more and more info toghether with better results.

    Well i just recently got my self clear on what the different timings mean on Ram Modules and started overclocking since ive succesfully clocked my Cpu, i wanted to do more

    The Modules are 4x2 OCZ Reaper DDR2 800 Mhz.

    It actually went pretty well, i got it from Standard Timings of 6-6-6-18 CR T1, Voltage of 1.8
    To Timings of 4-4-4-12 CR T2 voltage of 2.2.

    AI Dram Twister is set to strong in my bios, for exstra performance, and Transaction level is 7 for overall better performance.

    All Runs Stable as far as ive tested it.

    The Modules Mhz is set to Auto within my Bios, everytime i try to change it from say the lowest which is 800 Mhz to the next which is 961 Mhz, it want boot, not even if i up the voltage ?? Is that because i need to Raise the Timings to get the faster ram ?

    I have also Tried to make the modules run with the CR T1 instead of CR T2 which would increse my performance as far as i understand it, Again it will not reboot, ive tried different things like raising the voltage and lowering the Mhz of modules, and so forth.

    Well i might not be very clear, ive tried explaning it as best i could with the limited experince i got.
    Looking forward to some help and a greater understanding of how Overcloking works.

    The only programs ive used to test my machine in is Everest Ultimate edition, and MEMTEST, should you know of any other that would be great...as i think everest is a bit limited in it benchmark.

    Hey, welcome to Pure OC!

    You'll probably need to loosen your timings if you want your RAM to boot with a higher frequency. It's a tradeoff, unfortunately. You'll get more out of frequency than you will timings, so go for the higher frequency. The performance gain from timings isn't too big, so I wouldn't focus wholly on them. Raise the timings to 5-5-5-15 and see if it'll boot. If it doesn't, then loosen to 6-5-6-15 and see if it boots. Loosen them a little bit at a time, so you don't lose as much performance with each bump. Alternatively, loosen them quite a bit, and then go back and try to tighten them. I wouldn't push the voltage too far past 2.2v, so try to go with timings before a voltage boost.

    Have you boosted your northbridge's voltage at all? With 4 sticks of RAM, it is quite stressed, and it might need a little bit more juice. What are all your BIOS settings?



    For benchmarking, you can try 3DMark Vantage, 3DMark 06, 05, Super Pi 1.5XS, Sandra (SuperPi+Sandra for memory/CPU, rest are whole system benchmarks)

    to test stability, try LinX, IntelBurnTest, OCCT, Orthos.

    I don't think that you'll see a whole lot of difference from a RAM OC, but if you push that CPU more, your numbers should go up a bit!

    change these to compatibility/stability mode. it might help

    Default Thanks for your answer.

    hey again.
    Well before i started my little experiment with the ram, they were actually working at timings similar 6 - 5 - 6 - 15 timings.
    Before i start doing anything on the northbridge can you then kindly explain to me how it is affected by the amount of ram in my computer, dont really get that, have NEVER touched the northbridge in any case, cause i hear of to many unlucky people burning there hardware while boosting the voltage on it.
    The voltage of the ram is on 2.2 now, and should be able to handle alot more at least thats what OCZ says, but then again you might be right.
    Well erhm ALL of my bios settings :P .thats quiet alot, can you narrow it down, is there by the way any prog out there that can quickly scan it, so i dont have to write everything down i have changed ?

    Ill report back soon with some results on how it went with your advice

    Thanks again

    UPDATE

    Ive now for the past 2 hours been testin different settings and timing, but NOT touching the Northbridge voltage yet, The most stable Configuration i got was this
    Ram Timings is 5-6-5-15 running at 1066 Mhz with a Voltage of 2.1
    Cpu i clocked from the previous 3.6 Ghz to 3.78, which isent much at all.
    I can get it to boot as far as 4Ghz but then it will not load windows just freezes in the process of loading it, or i get Blue screen of death and it restarts, so now im at an dead end as far as my experience with doing this goes.

    The funny thing was (Before i figured out it wouldn start windows) when it was running 4Ghz, i only had to options left in my Ram Speed, one was 961 Mhz the other was 1186 Mhz, so when i up the Ghz of the Cpu, it gives me fewer choices of speed to work with, i worked fine on the 961 Mhz solution, but when i tried the faster one, no matter how much i kicked up the timings of the Ram i couldn get it to boot, so after that i went back to the 961 Mhz, cause i wanted to see how my 4Ghz and 961 Mhz Was doing in Windows, never got that far before realising it couldn load windows or i got the anoying BSOD, so i started backtracking and ended up with the before mentioned specs

    Ram Timings is 5-6-5-15 running at 1066 Mhz with a Voltage of 2.1
    Cpu i clocked from the previous 3.6 Ghz to 3.78

    So to sum it all up, do anyone out there have anu advice for me ? as to how i should proceed, something im missing bout the overclokin i did and so on ?

    Thanks in advance.

    the northbridge houses your system's memory controller, with 4 sticks of overclocked RAM, it might appreciate the extra juice that some more voltage would provide it. With a high FSB, it'd probably be a good idea to boost it, even just a little bit. I find it unlikely that you will fry your northbridge by overvolting it, unless you slam like 2v into it.

    there should be an OC Profile in your BIOS that you can use to save all your settings so you dont have to constantly reset it.

    how is your CPU voltage?

    can you pls provide a screenshot of RealTemp, and the Memory, Mainboard and CPU tabs of CPU-Z ?

    http://img20.imageshack.us/img20/5889/79476112.jpg <---- Link to Cpu stats after i reverted back to normal cause after Running Intelburntest, i got instability on even stanard, and thats was on the 3.6 Ghz ..dont understand never get errors or anything on that setting, so im off froim scratch, only one thing i can think of, might it be because i didn give it exstra power when OC'ing it ?

    http://img14.imageshack.us/img14/6575/memoryooz.jpg <---- Link to Memory also after reverting.

    http://img196.imageshack.us/img196/2319/mainboardl.jpg <---- Link to Mainboard

    The only way i can read the temperatur of my rig is by some fan controllers with Temp Sensors i modded into my case from Scythe.
    Havent found a program that will alow me to read core temperaturs from either Cpu, Ram or GPU,

    But basicly im off from scrath after discovering the instability its now down to stock settings.
    3.0 Ghz Cpu.
    800 Mhz Reaper Ram.
    Every voltage meter in Bios is on Auto again, After doing all the instability test in Intelburntest i can say that its Rock Solid.
    So now i at least have something to work with now that i have a secure base.

    high temperatures can cause instability, too. this is why you need to watch the temps.

    IntelBurnTest / LinX are what ive noticed to be the toughest stability tests to pass, maybe what you were running before wasnt as tough on your system as IntelBurnTest.
