FSb fluctuations, it happens, nothing to be concerned about here.
yes, what are you trying to do with your machine? working with it or gaming with it?
it would be a good idea to full stabilize a lower overclock before moving on.
and Bios screen shot will help ppl help you.
You never fail to amaze me when you take your time to provide help. Thanks. I'll start off.
This machine is mainly for gaming. May do some photo work on it later. But currently it is filled with 100GBs of games. Thanks for mentioning FSB fluctuations, knew it happened and was never really worried about it, happened on my FM2+ mobo also.

I appreciate you being worried but I have things down well enough. You may not have known because of the jumble I posted recently about FSB OCing and 5GHz but I have fully stabilized lower OCs already that I've spent hours upon hours and days on each OC. I have found the lowest voltage stable voltages of these speeds (4GHz (1.27v), 4.5GHz (1.356v), 4.7GHz (1.428v), 4.8GHz (1.464v), 4.9GHz (1.512v)). What have I done to test stability for these OCs? Multiple runs of IBT Maximum 50 Runs (not including even more shorter 10,20,30 runs before going for 50 and did this for Very High also), 8+ hours of Prime95 (Small FFT and Blend), 8+ hours of OCCT, 8+ hours of AIDA, Benchmarking, Gaming, Compressing/Decompressing files). I do this for each CPU frequency I mentioned so it takes a few days for me to test stability and feel confident of my clocks. I have tested the speeds I stated previously with Manual voltage and Offset voltage. With High LLC and Ultra High LLC. With 2200MHz NB and 2600MHz NB. Finally I have tested all my OCs at 1600MHz CL11/13 timings and with 2133MHz CL 9 Timings (Ram went through 8+ hours of Memtest86+ and 2 1/2 pass through of memtest). So before I go on to talk about FSB OCing and 5GHz just know that I have perfectly stable OCs from 4GHz-4.9GHz that are even Temp stable (stay under max temps).
I only dabbled with FSB OCing for the FX chips and only out of curiosity. I used Excel to make the list of optimal CPU/RAM/NB/HT frequencies for each FSB starting from 200-300. Tried 325, 320, 280, and 260 while keeping CPU, RAM, NB, HT as close to my fully stable OC settings. Computer failed to boot so I had to force shutdown and enter the BIOS. 240 is the highest FSB that is bootable that I tested but again it's not optimal as I have to run my NB/RAM/HT higher than I would like. 226 was the FSB I chose upon and tested it at 4.9GHz and it passed 50 runs of IBT AVX Maximum.
Some people talk about having a little more luck getting higher OCs FSB OCing so I went for 5GHz which wasn't possible before with 2260 FSB. Tried it at the same vcore as 4.9GHz and it failed around test 5. So I raised the vcore by .01v -.02v, surprisingly the 50 run IBT Max was successful except the fact Max temp was over 70C. Additionally I tested with CnQ enabled with Power Saving power options so in between tests the CPU frequency and vcore dropped. Because of that I set my power setting to High Performance which keeps my CPU at 5GHz and my set voltage and I ran 50 Runs of IBT again. This time I did not see my CPU drop speeds or voltage below the 1.54/1.56v it required to run 5GHz. Not really being interested in FSB OCing I changed my FSB back to 200, set CPU to 5GHz, 2133MHz RAM, 2600MHz HT, and 2200MHz NB and started another IBT 50 Maximum run before I slept. Woke up checked my computer the IBT run was successful again but again my max core temp peaked over 70C again. Additionally all 8-cores dropped about 20MHz for about 4 seconds total during the several hour IBT run. After that I ran Cinebench, AIDA Benchmarks, Firestrike, and played a few games. Last time I thought I had 5Ghz stable I learned it wasn't. Cinebench scores of 5GHz came out lower than 4.8GHz, and even worse I got worse FPS on 5GHz compared to 4.9GHz/4.8GHz. This time around my 5GHz OC scored better than all my previous OCs, scored higher on all the AIDA benchmarks, and did not have the low performance my previously unstable OC suffered. Only thing the 5GHz OC suffered in was benchmarks that were heavily related to memory. Why did it suffer? Because I was running 2200MHz NB compared to the 2600MHz I was running in my previous daily OC settings. Because of that I set my NB to 2600MHz, lowered my CPU vcore by .006v and ran another IBT 50 Max run and left the computer for a while. I just came back from work and the IBT run was successful again. This time the highest HWInfo detected my CPU vcore was 1.56 instead of 1.572 spikes (+1). Now I will be running some benchmarks again to see if the 2600MHz NB allows the 5GHz OC to score better in memory related tests compared to 4.9GHz with 2600MHz NB.
Sorry for the long writing. Had to sort of prove that (to Flail) I had the hang of things as far as multiplier OCing and that FSB OCing was only a side interest as I thought 4.9GHz was my max. Glad you tried to help on the question i was asking late last night or early this morning but I ended up figuring things out after playing with settings.
Here is a screenshot of what seems to be my latest successful IBT Max 50 Run with 5GHz, 2133MHz (9-10-10-27), 2600MHz NB/HT. As you can see the only negative things I see is that Core Temps hit 80C (ouch) and that CPU Frequency dropped to ~4980MHz during the stress testing. Not so much worried as I shouldn't hit those temps while gaming. I don't really benchmark, fold, mine, etc. If I'm not gaming I'm web browsing/watching videos most of the times on this PC. If you see a problem in my screenshot (Flail) or anyone else leave me a reply
