I'm starting to wish that I had in fact purchased the i3, but at the time, I really didn't have the funds to spare. (Nor did I have the funds to spare, purchasing the second Z170 mobo, either, but I sort of managed. Thank goodness for my stash of Ramen.)
Trying to cut back my spending in Feb. Maybe I'll get an i3 or an i5, but I really just want a G3900 Celeron. (Oh how I wish that Intel released a Celeron or any under $70 CPU with the HD 530 iGPU. That might be something to play with, and I'm guessing, most web-browser / desktop workloads, would benefit more from the bigger iGPU, than more L3 cache or a few Mhz faster CPU core.)
Edit: Update. I tried 135.0 BCLK on my second rig, at 1.300V, and it seems stable. That's 4.455Ghz. Not too shabby.
So I tried that setting on my first rig, and it started freezing up, even in BIOS. I finally was able to get in and juiced it up to 1.325V.
OOPS. A STOP 0x9C BSOD. Guess it doesn't like that. Let me try 1.350V on the first rig.
Also, I just noticed, CPU-Z is telling me that my memory is in "Single" channel, but it's showing the correct 8GB size, of both sticks. I put both sticks into the two slots nearest the CPU. Is that not channel A/B? Do I need to put them into slots 1 and 3, or something? Weird.
Edit: I do need to put them into slots 1 and 3. Didn't realize that. Also, manually set the DRAM timings for 2520 RAM, to 16-16-16-36, same as the XMP 2400 timings. (Actually setting XMP will disable BCLK OC.)
Edit: I got a STOP 0x101 BSOD on the first rig, with 1.340V and 135.0 BCLK (4.455Ghz). So I'm reverting that box to 130.0 BCLK (4.290Ghz), and 1.300V. It seems stable there, doesn't seem to want to run at 4.55Ghz at any reasonable voltage.
