    So last night, I got a bsod pertaining to memory_management (0x0000001A) while running prime95. I turned off my computer and left it thinking I would fix it in the morning. Come morning, I turn on my computer, and login and bsod's on me right when I get into my desktop. Here are my specs:

    Default Re: Question concerning my RAM and Q8200

    Both myself and Kick have had/have currently Q8200 experience so post away with any questions.

    I would advise that you record/commit to memory your GPU overclock clock speeds and any voltage tweaks to the GPU if applicable and then restore the stock settings. Not saying your GPU OC is unstable, just that a mix of a GPU OC and a semi stable PC while ocing may cause errors not directly attributed to what you may be tweaking at the time. It's like the old addage, something can be greater than the sum of its parts. A marginal PC and a perfectly stable OC'd GPU can combine to produce bigger errors.

    I can see you getting 2.8-3GHz on virtually all stock voltages. Set the Vcore to Normal or manually to the VID of the |CP|U, CPU Term manually to 1.2V, PLL to 1.5V, ICH to 1.1V, ICH I/O to 1.5V etc and your RAM to its rated voltage. Now crank the FSB up to reach 2.8GHz, ie a 400 FSB and alter the RAM multiplier to keep the speed at DDR-800, which ideally atm works out to 2.0D/B (Try D first, then B)

    The only advanc ed timing I'd change for this first step is Static tRead. Set it to 10 for testing purposes, check stability briefly with 10 runs of IBT, then using Memset, lower tRead to 9 and hit apply. If the syatem remains responsive lower again etc. As soon as you lower tRead too much the PC will hard lock. If for example it hard locks at tRead = 7, then you can assume 95% that tRead = 8 is the lowest stabe value, so go into the BIOS and change both channels to 8. Now do an over night test if you wish, or even another 10-20 IBT run, then move up in clock speed.

    Default Re: Question concerning my RAM and Q8200

    From that template, I can see ri9ght away why. You are pushing your RAM way too much. Even with looser timings, DDR-800 won't go much over DDR975 on average. This is with a voltage increase which you have not done.

    In all honesty, for much past a 440-450 FSB you will need DDR-1066, regardless of the voltage and timings you use on your existing RAM. Some RAM responds well to a timing change, but high quality "non enthusiast" stuff like GSkill is usually tightly binned. There comes a point where you cpould set 10-10-10-30 timings and still not break DDR-975.

    As in my first reply, you may be jumping up in clock speed too quickly given your relatively low multi and only DDR-800 RAM (plenty if you have a multi of 8-10, but not 7). Try 2.8GHz, get that stable and you will then learn what voltages need increasing as you OC. You will see the pattern eg, a couple of ticks Vcore and VTT increased a tick for 2.8GHz stable may mean the same need increasing again to get stable at 3GHz.

    Personally my aproach has always been to set the highest OC I think is possible right from the start and work on getting it stable rather than gradually increasing. Unfortunately your RAM isn't able to keep pace with such a method so slow and steady is the only way. Your RAM is 100% stretched beyond its capabilities.

    Default Re: Question concerning my RAM and Q8200

    Alright, I'll see if I can get 2.8ghz stable then. When I move up in clock speed, will there be a time where I will need to increase the tRead? I was reading reviews when the ram first came out and people were getting 950mhz+ on 2.2v which I did. I put a 120mm fan on the ram and nb so I thought that was ok to keep it cool enough. Guess not haha.

    I got it over 3.0ghz by following what kick said, first finding the limit to the ram then increasing the fsb based on that limit. I was thinking the 2.2v to the ram was good enough to make it perform over 900 mhz.

    EDIT: Just realized I set my stock timings wrong in the template. They are supposed to be 5-5-5-15, not 5-7-7-24

    Default Re: Question concerning my RAM and Q8200

    Well in addition to psychos points.
    1gb memory modules are easier to overclock than 2Gb ones but 4 sticks are harder than 2 sticks .

    You say you got 950 ddr2 speed with 2.2 v using a multiplier such as 2.4 or 2.6?
    Did you test the memory with memtest at that speed,how many passes did u use.
    Is that correct?
    Did you switch to 6-6-6-18 timings at the point you found you needed 2.2v and find you didnt need as much voltage?
    You may not get the memory running at 950mhz + at 5-5-5-15 timings when you are also stressing the cpu and mch.

    At what point did you have to use 2.2 v was it at say 940,930?

    You say 2.2V should be plenty to make the ram perform over 900mhz,well u say it is but your specs arent just OVER 900 mhz the bios shows 940mhz + theres a big difference between 900mhz and 940 for 800mhz rated ram when you are overclocking the cpu and volting up the mch also.

    The settings you posted..? did you have some testing at say 450cpu ref (1800 fsb,900mhz memory speed, 3.15 Ghz).
    How did it work out,any errors?


    also the mch V seems a bit high at that fsb posted.
    cpu term Vshouldnt be greater than cpu coreV in bios.
    473 cpu ref well the cpu voltage you have should be plenty,depending on cpu ViD.

    Ill just point out again .. as Psycho was saying the gskill memory is reasonably well tested(binned).
    Mine needs 2.08 volts in bios to operate at 990mhz ddr2 speed at 5-5-5-15 cas.
    2.22 volts in bios to operate at 1010mhz ddr2 speed at 5-5-5-15 cas.Thats a v big increase for 20mhz memory speed.

    Generally it doesnt like over 1000mhz at all,not just for me but in reviews etc,best speed I can obtain without risking it permanently failing is around 1060mhz.
    Luckily for me 1000mhz is all i need accepting q8200 will only get to 3.5ghz,or Q8400 will only get to 4.0ghz on the board without strain or this validation snapshot stuff which for me doesnt mean a lot.

    As Ive posted tho,it will hit 945mhz very easily at 4-4-4-12 timings with like 2.12 v.
    Other people have had slightly different experiences with different boards but Id say thats average for it.
    945+ with 4-4-4-12 timings is where the wall starts .950 I think needed around 2.14,maybe 2.16.
    960 it was into late 2.2v territory say 2.26-2.28V.at that point i just eased the timings out to 5-5-5-15 and it was back to easy street, like 2.0V-2.1V,for the next 80mhz ddr2 speed or 40 mhz cpu ref if you like.
    So its happy all the way to a 15-20% memory speed increase at reasonable voltages,after that it has to be pushed a bit.

    I hope u see what Im getting at if we translate it directly to your memory,lets say with 4 sticks even tho they are 1G your speed limit may be around 940 with 5-5-5-15 timings and 2.2V or 2.22,maybe its around 950.maybe you will get to drop the voltage down again for another 30 mhz or so if you relax timings out to 6-6-6-18 or maybe not.

    Ive seen+ someone recommended adata memory to me the 800mhz stuff supposedly runs a dream up to 1066mhz+ with decent voltages and timings,some other brands too.
    However the gskill is what you have and I reckon if you can get 3.33Ghz cpu speed up + memory bandwith and latency is up near the limits u wont notice much/any performance difference between that and 3.4 or 3.5 Ghz.

    What is your cpu vid? my Q8200 was 1.225V my Q8400 is 1.2875.

    edit: I mean should I drop my cpu speed down below 4.0Ghz yeh probably because the performance difference between that and 3.92 Ghz,u dont notice it,but i just like the even cpu number.Did I drop my Q8200 down to 3.43Ghz yes,I had it at 3.43 for like 4 months out of 12 but I think ill just hold on 500 cpu ref from now on,until the upgrade bug bites again.

    The other thing is the gx cards as psycho mentioned above..I only have the one viable Pcie card slot. can you pull one card out and do without physx sli and all that until you see what you can achive with one.
    I dont know how much that clouds up the overclock issue.

    I was using the 2.4 multiplier. I actually didn't run any tests when I hit it because I gave my friend my cd. I have it back now so I will go to do the tests when I get it up that high again (if I can).

    You may not get the memory running at 950mhz + at 5-5-5-15 timings when you are also stressing the cpu and mch.
    I didn't switch the timings because the ram was still cool (did the touch test) with 2.2V. Should I of just raised the timings? Does increasing dram voltage decrease stability in the long run?

    I don't remember correctly, but I think it was 930 since I was incrementing the fsb by 5.

    I did a IBT for 10 runs at 3.00ghz but thats it. No errors.

    I was looking at your voltages and basing it around there haha. Is there a general rule of thumb on how much it should have because I never usually know which voltage to increase if I get an error. I was running at base voltage for CPU volt, 1.2875.

    Generally, though, if you have a fan pointed at your ram, voltage doesn't really make any difference in heat right? It just wears your ram out faster. So does me putting my voltage at 2.2 hurt it in any way?

    Are your timings for your ram 5-5-5-15 also or 4-4-4-12? Because I was reading online that 6-6-6-18 makes a bigger difference from 5-5-5-15 than 4-4-4-12 to 5-5-5-15. I really don't want to increase my timings but if it's what I have to do, I'll have to try it.

    I'll see about the changing of timings.

    Would you see a difference in like fps in games though?

    EDIT: Also, whenever I restart my computer, when the computer tries to turn back on, it jeeps cycling on and off. I always have to turn it off via psu and clear the capacitators before turning it back on and when it gets into Bios, it says that I had an unstable OC even though it ran through 10 tests of IBT with no errors.

    Default Re: Question concerning my RAM and Q8200

    1.Use memtest in windows,give it at least 15 min before moving on ,start at say 900mhz then maybe each 10 mhz of mem speed after that.

    I didn't switch the timings because the ram was still cool (did the touch test) with 2.2V. Should I of just raised the timings? Does increasing dram voltage decrease stability in the long run?
    Well cool to the touch is one thing but it doesnt tell you much about what speed the memory will run and and for how long with the case cover on.
    Does increasing the voltage decrease stability in the long run.If you mean does it shorten memory life,yes probably:
    My ram at 1.85V might be expected to last 60000 hrs
    2.1V 50000-60000. 2.2V 40000-50000. 2.3V 20000-30000. 2.4V 10000 hrs or it could stop working anytime. 2.5V might work for a year,might stop working the next time you turn the pc on due to voltage surge.
    Are these figures right, no just guesswork.
    I also dont know why gigabyte have the option to apply more than 3V to the memory .
    Would I personally run my memory at 2.3 V in bios,yes IF there was a big performance gain.Otherwise no.
    Check out the pc health section in your bios when you post up,2.2V dram for me gives an indicated 2.1786V(2.18).

    My ram timings are all 5-5-5-15.6-6-6-18 will drop your performance ,it just depends how much faster you can get the memory to run.
    It also depends on the multiplier.
    Increased fsb speed also gives increased performance.

    I was looking at your voltages and basing it around there haha. Is there a general rule of thumb on how much it should have because I never usually know which voltage to increase if I get an error. I was running at base voltage for CPU volt, 1.2875.
    Your VID is supposedly 1.2875V.I think of that as being the maximum voltage that intel has determined my cpu needs to run at standard clock speeds.
    For sure at 2.33Ghz your cpu might run happily at 1.20V all the time but intel says it may need 1.2875V at that speed.
    Im not sure how you decided on 1.29375V cpu either.
    My cpu core voltage in bios is 1.39375V .At idle that equates to 1.375V approx,under any kind of loading the voltage drops to 1.36.

    So while testing your cpu core V may be dropping to 1.26V,which might be fine, or it might not.Even if you are just trying to clock up the memory you are still increasing the cpu speed,unless you dial in to use only the 6x cpu multiplier.
    What I would do is to dial in about 1.32v for the cpu voltage to cover the .03V approximately of vdroop.
    Using LLC enabled or not ,well thats up to you,I have to .
    Using that voltage should cover you for awhile at least on the overclock testing.

    As above 1.38V on the mch ,memory control hub,at the speeds you are at seems v high,and it doesnt leave you much /any room to increase it later if needed.Maybe because of 4 sticks it needs it but have you tried like 1.30?

    Intel burn,well Ive used it,but just 5 passes on my Q8400.I probably did 40 total at full speed on my Q8200.
    For most of my testing I used OCCTas an intermediate test and let it run for an hr(when it didnt give an error after 5 minutes )
    At final clockspeeds a good long 10 hr session of prime 95 + then let it run a full day .Some people let it run 48 hrs,I never had the patience for that .

    Default Re: Question concerning my RAM and Q8200

    There are still a lot of settings in that profile that are a little out. For instance the clock drive settings should be 800 and 900. Setting MCH clock drive to 700 at this kind of speed will yield no results and may actually have a destablizing effect. You also don't need 1.4V CPU Termination for any clock speed. My Q8200 was fine with 1.28V. More is not better in the case of CPU Termination and reference voltages, like it is with Vcore. In these cases you need the correct voltage setting rather than more volts.

    Altering RAM timings is for stability not for temperature. To be honest, if you need to raise timings to 6-6-6-18 then you'd probably be better off with a lower OC at 5-5-5 (run benchmarks to possibly confirm this). There comes a point where no matter the voltage and timings, the RAM simply won't go any faster. Like Kick said, DDR940 is significantly higher than DDR-900. RAM can be so sensitive that DDR900 may work fine and DDR904 may fail, let alone a 40MHz increase.

    Below is a slightly altered profile that I'd use to test 3.0GHz after first loading Optimized Defaults to restore the right clock drive and other hidden settings:

    You can re-enable speedstep etc when you hit your OC target/max.

    Now you're trying 3.0GHz, it's worth running prime. I'd leave the Large FFT test going over night. this is generally enough stress combined with IBT to confirm CPU stability and is also more stressful on RAM/MCH as well as cooling.

    tRead may actually be able to be lowered later. I ran 486 FSB with tRead = 9 on 2.00D quite comfortably.

    Realistically I can't see you getting more than about 3.1-3.2GHz with this RAM. You'll be limited to around 3.4GHz +/- 100MHz anyway, so changing the RAM probably isn't worth it. Q8200's aren't the best over clockers.

    It also depends on the multiplier.
    Increased fsb speed also gives increased performance.
    I think that if I have to increase my timings to 6-6-6-18, might as well have a lower overclock to keep them at 5-5-5-15 like Psycho said.

    What do you mean how I decided on 1.29? I just bumped it up a notch to make my computer stable. Is there something I should know when increasing core v? For me theres, approx. .02 vdroop under load.
