AMD Kaveri A10-7850K Overclock Guide - Page 133

post #1321 of 1334
Allrighty than... biggrin.gif

I don't know where to begin, the post might be without order but anyway,,

I've experienced very confusing things while doing this, if something is wrong with my BIOS or MB or me or whatever let me know.
First of all i'll start from the end, if was so mad of playing around i've OC'd the CPU to 5Ghz and let a loop run with prime for CPU, valley for GPU and Aida for RAM and HDD's. It looped for 12 hours without any problems. The Vcore was ~1.52V while 20 C from thermal margin. I've used the XMP profile 2 2133 for the RAM as without any OC it wasn't stable at 2400 previously, the room was a sauna from the heat produced but the point is that it passed all the tests. Also I've bumped the NBVid to +0.120. But at any overclock I encounter the same thing, no matter what I do. When I let it idle for some time, it freezes, sometimes after 10 sec sometimes after 2 hours or so. Now I've also played with all possible combinations, I've put it down all the way to 4, played with the CPU, NB and RAM voltages, from min to reasonable max, i tried every possible thing and combination as gapottberg suggested, I've tried with LLC from Auto to extreme for the CPU and NB and default RAM profile (+variations of extra voltage) also and no luck, and the Igpu is disabled.
The strange thing also is (as suggested by many) disabled the following, turbo clock, auto clock boost, c6, cool & quiet, apm, svn and so on and same thing.
(also played with all the combinations of these)
Here comes the interesting part, I've bolded cool & quiet because when It is disabled the first two theads OC to whatever I set them to but the third and forth stay to multiplier x17 (1.7Ghz) when i enable C&C they go to for example 4.0 if set to x40 but when I stress them the whole cpu goes to ~3 Ghz. The only workaround to this is to disable C&C and than if i do that 3rd and 4th jump from x17 to x40 back and forth and than when I unplug the cpu fan (the fans on my radiator) and to connect it to my fan controller and then set with AMD Overdrive with the little green button on the top to keep the cores at max freq set by the BIOS and the multiplier stays up!
I don't OC with AMD Overdrive because I've noticed that the settings for NBVid don't stick.
Any thoughts or should I throw the whole thing and go buy a new CPU, MB and RAM, I need this OC because for example on stock settings 3.7 + 4.0 turbo, on CS GO benchmark the average is 60 FPS! but when on let's say 4.4 it's 140! The source engine is very CPU bound and as I've said before I have a dedicated GPU. It's a huge bottleneck so at least I want it make it stable at 4Ghz, but as things are right now even that is not going to happen.
The point is it runs fine when on load for days (no matter how crazy is the OC for this MB) and everything is fine but when I let it loose and let it idle it just a matter of time when
it will freeze. gunner.gif

Have you reset BIOS with the cmos battery yet? I think the big issue here may just be Gigabyte BIOS. I have experienced strange things that only a cmos reset would seem to fix.
Last resort would be to reinstall OS.

I am a bit baffled you were able to run prime at 5Ghz with only 1.52v. What are your CS:GO frames at that clock?

I have no more nails from removing the battery, I know use a screwdriver smile.gif I've used another OS from another drive I used before on that machine, same. The CPUvid was set to 1.55 but the core power both on load and idle stayed at 1.52. I'm baffled to, It's really strange, I can torture the PC for hours and no problems and than when on idle it just trips over itself.
On CS:GO as i've said on stock CPU settigs the fps are a disaster (60). From 4.0 (OC) to 4.5 It goes from 100 to 150, For every 100 Mhz around 10 FPS, and from that point to 5Ghz roughly 5-6 for every 100mhz and @ 5 it's 176 on Mr. Ulletical's Cs Go Fps Benchmark with all the settings cranked up, motion blur fxaa and v-sync disabled and x2 MSAA @1080p that is. I don't care about going more than 60 on all games as I have 60Hz monitor and I use V-sync, but Cs Go is a different story, it really matters a lot... input lag and so on, basically you know, the more the have on cs the better the experience. But on half of my games the frame times are terrible because of the bottleneck.

I've read this, I'm still thinkering around, Thanks for the links. Totally off-topic.. Just for illustration, I've put CSGO with Virtual Super Resolution to 4K and the same settings, the FPS on the benchmark and in game stays the same as on 1080p smile.gif I was expecting to be bottlenecked but not on this level...

And while I'm here, I've read that vrm symptoms of overheating is reducing the clock automatically, but can it cause problems like mine because I've disabled all cpu power management features? On the other hand I suppose they are heating up the most when on full load...

Also to be on the safe side can I just leave the RAM at 1.65V, it's rated max voltage for xmp profile 1 (2400mhz) and use it on xmp 2 (2133) or is it too much.

My ram is totally stable at 1.4V and it runs at 2400MHz. So that could be undervolted too biggrin.gif
post #1327 of 1334
I've left it @ 1.65, just for good measure, I don't care if it goes kaboom smile.gif I will buy a new MB, CPU, RAM for the reasons I've stated above but I don't know if I can (or should) wait for Zen or to just go and buy 6600k.... As for my OC it still work in progress but I've managed to make it somewhat stable (1 reboot per 24 hrs smile.gif ) but more on that later.
post #1328 of 1334
1.65v for DDR3 is nothing, I run mine at 1.7v and have done so for over a year. And it's no threat to the Kaveri memory controller, either.

As for a 6600k . . . yech! Hold out for Raven Ridge, or at least see what Bristol Ridge has to offer. If they improved the l2 it might be worth a look.
post #1329 of 1334
Sorry for Off-Topic...In USA and most of EU new items arrive quickly after launch, but here in the Balkans we are a black sheep... If Zen comes out let's say in Jan, we will receive it May-Jun and for a couple months the price will be pumped up. So I made my mind and I didn't want to wait for half a year and I've purchased 6600k with Gigabyte Z170x G1 Ultra Gaming MB. I've sold the CPU (7850k) along with the MB and RAM, A friend of mine made a discount for the new parts and I've sold the old ones for 190 EUR with that I added 200 Eur and if you ask me it was a good deal (again the prices here are stupid) and the price of 390 Eur total is with a big discount, regular price for that is 470 Eur.

On-Topic... As much as I've tried to OC the CPU (and got to fairly stable 4.6) it wasn't a match for the GPU in any way. The bottleneck was ridiculous. Honestly I didn't expect that much of a difference. On boot-up, launching programs and so on there isn't much of a difference from the overclocked Kaveri to the 6600k, but on games it went to let's say NFS 16 from 35-45 FPS with big dips to 24, to 70+ constant with everything maxed up, as for CS GO on the benchmark I've mentioned before the FPS jumped from 170 Avg to 400 biggrin.gif

As for the MB, I liked the EZ OC noob button, it just asked me what CPU @ what clock, and it locked the multiplier at 44, with c states on and dynamic voltage, The LLC and voltage was calibrated automatically, but no doubt I'll thinker with it later on, for now I just want to work/play.

Anyway Thanks guys for the support and your time, I've learned a bit from this experience and I'll gladly help to someone if I can thumb.gif

Oh sorry, thought you meant an old A10-6600k, not the Skylake chip. Never mind!
