Hello Everyone,

So I recently switched my motherboard to Biostar. So far it seems to overclock better. It is keeping with lower voltage than my old Extreme4-M, which is keeping the CPU cooler, and it seems to be more stable.

Here is my problem. When I tried to push up to 4.4Ghz I get blue screen. I got three different error codes.

First I got a typical 0x0000003d.
I have my baseclock at 102. It was stable when I tried 102 Base clock and x42 multiplier, but I dropped it to 100 and tried. That failed same error. So I changed the base clock back to 102 and then I decided to just drop the RAM from 1600Mhz to 1333Mhz to rule it out as a problem.

Second BSOD 0x0000007E.
I read this relates to problems with the OS. I am using Windows 7 and for some reason it didn't make a 100MB partition like it usually does this time. I've seen it not do this before, so I didn't pay it much attention. Windows tried to boot into recovery mode from the BSOD it got before, and I let it and got this error. I heard some say that the small partition just holds recovery files so I thought maybe the partition caused this BSOD.

Third BSOD 0x00000050.
I just restarted and tried to boot Windows normally, and avoided the recovery mode. This error said something about a graphics card error maybe, which confuses me since the graphics card hasn't been altered by the system BIOS. It is overclocked using AMD Catalyst Control Center, but that doesn't happen until the system boots fully and the program starts. The BSOD is happening as the Windows logo spins.

Using monitors I know my CPU is only using about 1.188v while at full load, which is less than the maximum aloud 1.250v. Still I tried using the offset mode and gave it a little more voltage which didn't cause any change. The only setting I am changing is the CPU turbo so I am confused what is causing the issue. It doesn't really make sense.

Any ideas? Thoughts? Suggestions? Thanks ahead of time.

In my experience when this sort of thing happens the best conclusion to draw is that the processor is not stable enough to overclock even a little. Part of quality control is that the manufacturer only tests stability at core and boost clocks.

With modern architecture the ability to overclock (especially speaking of Intel) is getting to be more of a privilege or even dead luck.

I'd be happy with 4.3Ghz out of a BioStar motherboard. If your seriously into OC'ing you need two things:
- a motherboard that can provide high power and stable voltages
- BioStar makes Mostly lowend boards, not the best for OC'ing to high numbers, what model MB do you have?
- a good after market cooler (you don't mention cooler or your temps in post... this could be your hurdle)
- a basic Cooler Master 212 EVO is a good start....

There is no reason the Biostar board cannot handle it. Its a Biostar TZ77A. I previously had an ASrock Extreme4-M motherboard and removed it for the Biostar board. The ASrock is only an analog 4+1 or 4+2 . This Biostar board has a hybrid digital analog PWM chip and uses a 6+1 or 6+2 phase design.

I don't have the best cooler really. I have a $16 cooler from Rosewell with 6 heat pipes. I do edge on 80C with my current overclock while using Intel Burn In Test.Which is why I don't really expect to overclock much further without an upgrade, but its not getting hot and shutting down right now. It crashes while trying to boot so the CPU isn't even under heavy load, and it does it almost right away either while the Windows symbol is spinning or as soon as it vanishes. So there isn't even sufficient time for it to build up that kind of heat.

@FloppyNacho -
I am kind of thinking like you. I am wondering if maybe my CPU is just a poor overclocker because of being a poor quality sample. It doesn't really make sense for it to be an issue with heat, power, RAM, and I re-installed Windows 7 last night too which didn't fix it either.

Any idea how good Intel is about warranting the CPUs? I might play it up a little and say its having a little more stability issues than it is and try to get a replacement.

Actually my CPU is continuing to go down in stability. I used Intel BurnIN test and allowed it 12GB of RAM and it came back as stable with a base clock of 103Mhz and a max quad core turbo of 42. Then it had a blue screen, I dropped down to 102Mhz which fixed it I thought. I reinstalled Windows which then gave me a blue screen. I dropped the base clock to 100Mhz and tried again and it passed.

Here I tried raising the multiplier to see if the OS was the problem, and it booted with a multiplier of 43 but froze after booting. At 42 it booted and worked fine for a while but I tried to put it to sleep and it wouldn't go completely to sleep. I pressed the power button to shut down and it came out of sleep mode, so I tried clicking around a little to see if it was okay and VLC player started looping the same 5 seconds over and over.

Now I have my system set to 3.9Ghz regardless of how many c ores are active which is a really minor overclock. I think I am going to contact Intel though because the system seems to becoming increasingly less stable.

OC performance isn't going to get real high on a BioStar, and if running 12GB of DRAM then you have an out of balance rig in the first place, socket 1155 mobos are aimed at runing 2, 4, 8, 16 or 32GB of DRAM, little to no effort at all will have gone into the BIOS for managing or setting up a 12 GB systtem...you might do better by making sure you have the latest BIOS and drivers, and making sure the rest of the rig is balanced

Judging by all of the specs I am able to find between the Biostar board and the ASrock board, it should overclock better.

I am not running 12GB of RAM. I have 16GB of system RAM. For the Intel Burn Test I allowed the application to use 12GB of RAM for running the tests. You cannot allow it the entirety of your RAM since it is partially used by the OS and background programs.

Also, I question highly if there would be a problem trying to run with just 12GB of RAM. Before I built this system for a while I had an i3-3225 in the ASrock Extreme-4M motherboard. I bought a 16GB 4 piece kit, but one was defective and the company was nice and let me return just the one defective stick. It had to go I think to California and I had to wait for the replacement to come all the way from Taiwan. During this time I used 3x4GB RAM for a period of nearly a month without issue while playing games, or running any other applications including the Intel Burn Test when I pushed my i3-3225 up to 3.5Ghz.

I have used the latest two BIOS updates for testing purposes. I have all of the latest drivers. I tested with two different CPUs also, an i7-3770k and an old Celeron G530. The i7 quickly becomes unstable now with any push over its base frequencies while the Celeron, though not able to overclock much, is perfectly stable with a slight FSB boost.

Well I had that idea a little before. I attempted using CPU Offset mode to boost it by .10v. It didn't work. See thats why I am so confused as to what caused the problem. Using the Toverclocker program that came with the motherboard, it reported that with a bus clock of 103 and a max turbo multiplier of 42 while all cores are active it never recorded using more than 1.188v. Thats when I ran the stress test with 12Gb of RAM. Using that much RAM the test took like an hour and it came back as stable. So then I pushed the clock multiplier at 44 and it failed, and then I tried 43 and it failed also. I dropped the base clock to 100 and then it would boot with the multiplier at 43 but it was so unstable it crashed within seconds of trying to open any programs. Adding .10v on the CPU offset didn't help and I am concerned to give it more since the monitor isn't reading as using that much.

Anyways I decided to leave it for the time being yesterday at 103 base clock and 42 multiplier and it eventually crashed also while just doing light work. So I am king of thinking the CPU might just be a poor sample. I have the old Celeron in for right now so I can do basic stuff and so far it hasn't had trouble with a base clock raise. So I don't think its the motherboard, but the Celeron is so far from the i7 it seems a poor test too.
