Athlon 860K, any one picking it up? - Page 207

I'm going to make a new build with the 860k purely for gaming. I will be running it with a R9 380 4GB and a EVGA 550W G2 in a Corsair 350D case (mATX).
Can anyone here recommend me a solid mATX mobo that will work with the 860k without any BIOS updates, and that also runs well on Windows 10? I'm planning on doing some light OC'ing aswell if possible. I'm looking at the Asus a88xm-plus which seems to support win 10, but I can't seem to find out which BIOS version it ships with...

When 860k has come out I bought Asus A88-gamer which was one of very few mobos supporting that cpu straight from the box. Also supports 2400MHz ram and crossfire(i ran 2x msi r9 2700x). Has great audio SupremeFX, great for overclocking. Absolutely no problem with drivers or compatibility, I've moved to Intel and MSI gaming mobo and this is giving me some serious headache, bios issues, incompatibility with vga(MSI as well btw!!!), drivers/apps not installing properly etc. I already miss Asus as it was a really smooth experience, absolutely no problems at all, everything working straight from the box.
My 8 mths old Asus A88x-gamer(still with warranty and receipt) is for sale(as well as my 860k)btw if anyone wants it:)
Bottom line: go with Asus.

With weather starting to get colder, I decided to take a shot at 4.3 and 4.4. I managed to get 4.3ghz stable at 1.5v. Thermal margin was around 17-18 but when I ran Batman AK, the numbers were completely safe so I'd call that a success. I know that 1.5 isn't the number I got it stable last time, so I might be over by .03. I bumped it to 4.4 and unfortunately was not stable. I'm unwilling to go past 1.5v so I suppose I have to accept that my max is 4.3.

I've learned some things since I last posted though.

1. My 212 Evo fan started rattling so I enabled Asus Q-Fan, which did silence the rattling (and sound overall). Turns out, I only needed 650~950RPM to cool stock frequency. It was running 1750RPM max speed this entire time and it never needed to. Now I have to replace the fan.

2. By going to Power Management and selecting High Performance, it acts as sort of a "soft OC" and keeps the frequency between 3.9ghz and 4.0ghz. Pretty cool for getting extra juice but don't want to restart to do it.

3. I've been running stock freq with cooling/power saving settings w/o that nasty default settings overvoltage. When I did it the first time (I posted about it sometime in the summer), it didn't work b/c I had the wrong sign selected. Oops lol! So what you do is under Offset Voltage, press + to get it to 0.00625 but change the sign from + to -. Now, it'll slightly undervolt but will still be stable smile.gif

Can a CPU-NB overclock affect CPU multiplier OC ?

Few months ago, I overclocked my NB by 200 Mhz, not adding any voltage, but just leaving it on auto, which was 1.138v.

Now I'm trying to break 4200Mhz barrier and I find my PC freezing randomly, sometimes during hours of gameplay, sometimes browsing, but most notably, it passes p95 smoothly. I'm wonderind if the freezes are the issue of NB needing more voltage for some reason, because I OC'ed the main part of the CPU.

Also, do any of you touch CPU Current Capability ? I've read on "Overclocking Bulldozer and Piledriver" that using that option is great, but I have just raised mine to 110% for now.

2000mhz NB can be very difficult to get stable on some boards. When I had an XBR I could not for the life of me get 2000mhz NB, my A88X-Pro will do it and the Gigabyte UP4 tops out at 1900mhz and even then has some stability issues there. I tend to leave it at 1800 unless I'm benching.

Well, on the positive side, I think NB was the cause of my freezings when OC-ing the multiplier. 2000 @ 1.14V, my PC worked for half a day before it froze. Thats much longer than it did last night, so I'm guessing that bumping offset once on the NB did the trick.

Now I'm at 1.15V and time will tell if this truly is the solution to my issue. Need to give it time though, as stress testing doesn't produce the freeze, even after few hours, but casual using PC (today it froze in VLC) seems to be the only method of testing for me.

Edit: Never mind what I said above, NB wasn't the cause of my freezes. I have a crappy chip which needs more than 1.43V to stay stable at 4100Mhz. LOL

I'm back on 1.13V at 2000Mhz NB and its working fine. At least this part of my chip does well.

Very interesting though, is that my PC froze 2 times in a row while using seek function on VLC player. Funny thing is that it passed hours of stress testing in prime95 before that.

I'm unsure. I don't touch it tbh

Yes, for 4.2 and 4.3, I have it set to 130/120% and maxed out for 4.3.

Apparently NB doesn't affect it, it was just the rest of my crappy chip which won't stay stable on 4100Mhz at 1.43v... Gonna be pain to keep it at 4200...

It really makes me wonder how Steamroller has such poor overclocking performance compared to Vishera. We're barely getting 100-200mhz over turbo clocks here.

I wonder whats the average ratio on bad vs good overclocking chips on this one. I really thought I would go 4.5Ghz with mine, and with this motherboard...

One thing I noticed though, at least on this board, my CPU never hit 4000Mhz on turbo. It always seems to top at 3900 for some reason.
After turning off turbo mode and OCing to 4100, I noticed an immediate improvement in my system startup, and general responsiveness of windows. That really helped the chip, even though it doesn't look like much.

Personally, I've owned 6 Kaveri chips of varying description at this point and only one of them would do over 4200mhz stable. That was my other 860k and it would do 4.8ghz with the right cooling, it might have gone 5.0 if I delidded it. I've had many, many more FX 6/8 series chips and all of them would do 4.6+ and most of them would do 5ghz with little effort besides cooling the VRM/socket area on the motherboard.
