Hello Everyone!
I've been so busy with college, already missed the forums and the people who I had helped and that helped me
🙂 I am now having a major issue with the BCLK to spike causing instability issues on browsing the net or leave my PC on idle causing a BSOD (hal.dll) which obviously means my overclock is not stable. It has been doing this for the past year (I've used ThrottleStop to downclock it so it wont happen) and finally to my conclusion I realized that the cause of the issue was that my BUS CLOCK jumps high when on idle, or browsing the net and mainly working on programs in windows.
I have not notice this until I downloaded a program called HWiNFO64 and open CPU-Z to check what is going on and then I saw this:
http://i.imgur.com/cdtdo40.jpg?1- 4.502ghz to 4685.ghz with the BCLK at 102.3mhz - This is very odd, I've been searching around and there are only a couple people who have notice this on "GIGABYTES" boards. Though my brand of motherboard is not efficient for overclocking especially when I need my VCORE to run at 1.80-1.92v for the i5 2500k to run @ 4.5ghz. (GA-Z68A B3H rev 1.3).
Yes, I have tried to clear CMOS and so on and still the BCLK will increase without even overcloking as well, though no BSOD. My temps are fine also, I have upgraded from the EVO to the NOCTUA NH-D14 recently and on prime95 the temps reaches to 68-70 C (core temps) and main CPU at 58 C which is fine and I don't see the BCKL to increase when benchmarking or playing games it only happens when it's on IDLE or in windows browsing the net and so on.
I keep digging and digging wondering why the BCLK jumps like that when I also tried to set it manually at 100.0 but it still go above that number and this is a very serious concern as the PCI-E frequency can cause instability issues to the GPU as well. I've also recently upgraded to the EVGA GTX 980 SC and I have noticed that my temps can be at 35 C then jumps to 45 C in less then a sec in the start of Heaven Benchmark 4.0 when gpu usage jumps to 99% GPU Usage. The temps does not spike very high like that where it should go slowly to the 40 C range, though this is what the "PCI-E" frequency can cause damage to the components.
- This had the same side effects on my GTX 560 ti (sold) and the GTX 760 (handed to my brother) that had followed and now really worried for my GTX 980 and the rest of my system.
It also had the "Power Cycling" issue that "GIGAYBTE" is well known for where I must NOT touch or move my RAM before it does this -
https://www.youtube.com/watch?v=6J2Qd3RevPQ - This person has fixed their issue by replacing the CPU but mine was a very different issue as it's cause by the ram slots which I also have another pair and the same issue I MUST wrestle onto the slots. It was happening when I was changing coolers from the EVO to the Noctua where obviously I need to clean out my system by removing the ram and so on, though I think I am sure that it was a malfunctioning board due to the "PCI-E" frequency. Though I am not worried when I do this only if my RAM need to be replaced or adding new paste to the CPU cooler.
I also realized that when clearing the CMOS by removing the battery and so on the BCLK will be at default but its .3mhz more and will still have that spike to 102mhz which is still dangerous. So when overclocking to 4.5ghz it will be at 4.513mhz instead of around 4.502mhz which I have to set the BCKL MANUALLY to 100mhz or 99.8 but again without overclocking the BCKL will jump to 102.3! when it should stay at 100.0 or less or what ever I set to manually...
Conclusion:I really really should go for the ASUS ROG mobo sometime but I really cannot afford it at the moment as I already saved up for the i7 4970k but not enough for a really efficient board I am tired from EVGA (old 680i) and now the GIGABYTE mobo. I really do need your help and I know there is a gigaybye forums but they also cannot help me and also explained it through support but again they do not provide helpful solutions or "think it's normal" and now lead me to the best knowledge of these issues are right here!
This is frustrating me I have tried everything from the BIOS settings and still don't know why it jumps like that and also I have found another youtuber with the same gigaybe motherboard that he returned to replace a new one and it was working BUT mine was a used board without warranty. If this issue cannot be fixed, please if there is anyone willing or have a spare old rog board for the 2nd/3rd gen intel CPU it will help me so much and willing to pay for the postage, so I can actually have a decent mobo without any issues. It's difficult for me to save money as I am still in college trying to pay for my subjects and equipment for IS (Information System).
I really do hate to ask this but now I am very concern that these issues were the ones that cause the GPU's to behave like that especially during idle due to the "PCI-E" abnormal frequency... This is now happening to my brand new EVGA GTX 980 SC ACX 2.0 which I still can RMA it but the temps does not spike on my other system so it still good just worried about long term effects on this mobo....
Again, I do apologize I'm very worried that my expensive components in my system will not last long... I really wish I had a mobo without issues I'm having really bad luck with "used" mobo's at the moment... should have saved more money on a brand new motherboard.
While I was typing this and checking HWiNFO again I've also found out why the temp spikes high in a sec -
http://i.imgur.com/Fjwr7hB.jpg?1- PCI-E 5.0 does not exist still and my PCI-E frequency should be 2.0 due to the i5 2500k. Now I am unsure what is going on if its sensor or the actual motherboard.
Thanks for reading this and taking your time, it appreciates me allot.
