Hello

I am having a bit of troubles. After overclocking my CPU ive been getting random BSODs playing games for maybe an hour or so. I have an i5 750 with a P7P55D PRO motherboard. I followed a pretty basic guide on how to clock it which seemed straight forward, I went from the stock 2.67 GHz to 4.0 because I figured, why not since I have really good cooling. followed the guide exactly and all went well as id expect. being clocked that high I only hit about 37C on full load so temp isn't a problem. but idk why I'm getting it. not sure what details to provide you guys but the specs are

intel i5 750
P7P55D PRO
2xGTX 560's
H80i water cooler
6gb RAM (2gb Kingston 4gb corsair)

Right now I got a System service exception bsod and the first bsod I got was paged fault in non paged area. after I got this last one I clocked down to about 3.4. any help would be appreciated, let me know if you need more info.

To start with I must say that I am a novice when it comes to overclocking but I have been experimenting with the exact CPU and have got it stable with the help of a very kind and helpful tom's member. One of the problems I had was memory, I got a number of BSOD but with memory management as an error instead of the one you had. I learned that when OC the cpu the memory OC's at the same ratio as the cpu unless you tell it not too. I am not the best person to offer advice in the situation and I am sure someone with more knowledge will offer advice by there are a number of you tube tutorials that show you how to make adjustments to the RAM. Yo "may" need to slightly increase the VCORE but I am not advising to do this until you get more sound advice. I am going out now but if you do not have any other replies when I return I will be happy to share the advice 1liquidpc gave to me.

thank you for the response. I was aware of changing the memory clock to match it. I belive when I went to 4.0 GHz I had the memory set to 1600 MHz and since clocking it down to 3.4 I clocked it to 13xx MHz (1365 I think?) don't remember the exact number but I havent gotten it again since then while playing games. its a shame cause I wanna push this thing to its full potential to 4.2 but I cant get it stable and don't want to risk any damage.

what settings are you using, are you sure you are stable, did you run prime/occt, if not then start over, if you ran them for less than 1hour then run them again for atleast 5h, what is your vcore, 37c is lower than low, only way you could get temps like that under load is if you left stock voltage, no not even then, those are temps one would expect in idle, what did you use to check your temps, my current system(sig rig) has a custom loop of 360mm rad and a 240mm rad and the cpu under load will go all the way to 70's low 80's, there is no way h80i could cool it to 37c under load, to check you temps use something like hwinfo/hwmonitor run it in background while running a stress test, watch your temps during the stress test and report them please

right now at 3.4 GHz its pretty stable, haven't gotten a bsod yet and ive been gaming 6+ hours at a time with the voltage at 1.0xx and at 4.0 I think it was around 1.3xx. what I'm basing my temps off of is my case has a core temp screen with the temp of all the cpu cores. I did find it fishy that itd stay so cool cause stock would sit around 28c on start up and get to 33c on full load and after the oc got to 37 at the highest. but I also have 2 120mm fans but ill run a temp app and see if its lying to me or not lol.

okay yeah it lied haha. its still low at 40-45c idle and gaming was topped out at 58. the vcore idle is 1.0xx and max is 1.2xx I'm not sure what the vcore should be at clocked up to 4.0-4.2 tho. I thought it did it automatically

so you have done zero stability testing, gaming will never work as stability testing, unless you use prime 95, occt, aida 64 you will not get that cpu anywhere near stable the way you are doing it, there is not a single game out there that could stress a cpu enough to be even considered as a sign of system stability and you have zero idea of what full load means, full load means all 4 cores 100% loaded, gaming is nowhere near full load

well lets calm down now alright I never said I was a pro at this which is why I'm asking questions, all I know Is I followed a straight forward tutorial based off this cpu and same board and did exactly what I was told and they said it was stable but I was getting blue screens and now clocked down I am not. and what does it matter, if I never get my pc to full load gaming then I'm fine. its working just great now. I just wont go to 4.2 then. it was a good processor stock so ill get what I can take. but thanks or the input

I have found a couple of sweet spots. 3.3 ghz has low temps and I can get the RAM clocked to very near base. 3.6 was good also but my temps at idle were about 50c and the RAM closer to 1500 mhz. I turned turbo off for both but otherwise made no changes.
