    Default Overclocking P35-S3G

    Hello,

    Since upgrading my RAM to 2x2gb cl4 4-4-4-15 2.2v ocz titanium i cannot activate overclocking without cause a dual boot which wipes my settings. When i had 2x1gb in i had successfully tested oc to 3.2ghz per core. I am using a q9400 cpu.

    I gather it is my timing settings that are giving me such trouble, but i don't know how to fix it. I cannot even oc to 8x350mhz without it failing. :(

    I upgraded bios to F5b - which i may not have needed to do, but it is the latest one on the website.

    If i leave cpu as stock and dont overclock, i am able to set my ram timing to 4-4-415 with 2.2v and have a 1:1 fsb:dram ratio. But as i said, soon as i try even small oc it dual boots and resets bios settings to auto.

    If someone can help me with this i would be very grateful, as i'd be extremely annoyed if it wasn't possible to oc with this memory.

    Oh and if it helps, i have rubbish case, thats falling to pieces, and using a stock fan/heatsink, airflow isn't possible as i dont have a side cover lol (get new case in 2 weeks tho hehe - coretemp said that my temps were under 40 degrees C while oc at 3.2ghz (on the old ram) so i dont think it'd be a cooling issue..

    Thanks in advance,

    Imperial

    Load and save optimum defaults a lot,after bios change,before component change etc.
    I personally dont know this memory /what speed its supposed to run at at these timings and 2.2 v.,or what you had before, etc. I and the people who would reply /have specs close to yours,might not be bothered going to the ocz site to check it out.
    Helps to post full system specs and bios templates too.
    Case isnt that important,its just a box,unless the wiring loom is suspect.
    Current Systems:

    Asrock p67 Extreme6.............. Gigabyte EP-45 UD3 ...................... Gigabyte 73 PVM S2
    Intel i5 2500k 4.8ghz................ Intel Q8400 3.8ghz......................... Intel D820 2.8ghz

    Genric PSU may be your issue or at least part of it as well. I doubt a memory upgrade would strain it much, but you never know? And I do advise you save up a buy something better, doesn't need to be larger, just not something named generic, or something generic in general

    Hey, when you added this ram or after you flashed the BIOS you did load and apply optimized defaults and save/reboot right? If not you must, so do that first. Load optimized, and then set only your ram voltage then save/apply F10 reboot BACK to the BIOS and set your Sata Settings again in Integrated Peripherals and advance BIOS page, then you can change the rest of your settings in MIT
    Try these settings, this should get ya going >>>

    Robust Graphics Booster___________ [Fast]
    CPU Clock Ratio ____________ [8]
    Fine Clock Ratio ____________[0.0]
    CPU Host Clock Control_ [Enabled]
    CPU Host Frequency (MHz)__________ [400] << I always advise 399 or 401
    PCI Express Frequency (Mhz)_______ [100] << OUCH Set this now to 100, thanks

    System Memory Multiplier (SPD)____ [2.00]
    DRAM Timing Selectable_______ SPD __ [Manual]

    Performance Enhance = [Standard]

    CAS Latency Time________________ 4
    Dram RAS# to CAS# Delay_________ 4
    Dram RAS# Precharge Delay_______4
    Precharge Delay (tRAS)__________15

    Set all below to highest value, then later lower one at a time testing as you go. Only the BOLD item is a kinda Must be set thing for 2x2, the rest you may leave in auto if you like but would not be the best for performance. You can set the rest later if you like after you get going, but I do advise you at least set the Bolded item

    ACT to ACT Delay (tRRD)_________ 3-4
    Rank Write to READ Delay________ 3-6
    Write to Precharge Delay_________ 4-8
    Refresh to ACT Delay______________ 52-62
    Read to Precharge Delay__________ 3-5
    Static tRead Value_______________7-10 (Set 10 here for now, this may be to low in Auto and can cause issues. Once you start tweaking your settings lower this first as low as you can get it as this has the MOST impact on performance)

    Static tRead Phase Adjust________ [Auto] << Always Zero/Auto


    System Voltage Control____ [Manual]
    DDR2 OverVoltage Control__ [+0.400V] +0.3-0.4 (2.2 is not often needed, that is only max allowed under warranty)

    FSB OverVoltage Control___ [+0.1V]
    (G)MCH OverVoltage Control [normal] << Set +0.2-0.3V
    CPU Voltage Control_______ [1.20v] << May need more, only you and your CPU know. I think you know what it needs anyway right, so you should be fine

    Thank you for your detailed reply.
    Yes i had set the optimized defaults, and i did again just before trying overclocking again,

    Refresh to ACT Delay______________ 52-62 <-- tried this from 62 down to 52
    Static tRead Value_______________7-10 <-- set to 10 (let others at Auto for now.
    CPU Voltage Control_______ [1.20v] <--- raised this to 1.30v (is definetely high enough for this low oc speed)

    Everything else i set to reflect the settings you told me. After I save and it reboots, it does that like double boot again (furthest it got was to the gigabyte splash screen). Then bios is reset to default values with my 'custom' values not in use til i Enable CPU host clock control.

    i'm getting bit frustrated to say the least hehe - feels at moment i have choice of 2x2 ram and stock cpu or 2x1 ram and overclocked cpu. I obviously want the first choice and hope that isnt asking too much from this motherboard.

    My PSU is actually a Jeantech one, so guess it isnt generic, just not as awesome as a corsair would be hehe.

    Is there anything you can think of that would stop me getting a stable OC using these low speed settings? I would habe thought those 2x2 needed settings would have resolved it, but clearly it hasnt :(

    Well you could try 399 FSB.

    Ahh, I thought you had Generic PSU for real because Generic is a Brand name

    Are you sure more Vcore is not needed, you can try out for that just to see if that is the issue, it will overvolt it and it would be enough for sure that way

    Did you set the other voltages I suggested as well as the settings you posted above, the ram and MCH?

    yeah i saw the other voltages and set them. I set everything you mentioned.

    I feel confident that the cpu voltage doesnt need to be higher than 1.30v for 3.2ghz overclock as when i used the older ram which was still ocz branded i didnt adjust any voltages left them all on normal and it worked.

    Got one of y friends playing with my settings now, he has overclocked it to 337x8 but any higher it fails.

    Maybe i do need a more powerful PSU. I know by having a 4870 gfx card i am close to the limit of it's abilities to power more devices.
