Under MIT current status, make sure there are timings listed for both memory channels wink.gif

I usually start by setting the chip to 1.40V@4.0ghz with fixed voltage settings and all performance scaling functions disabled (CnQ/turbo/CPB/APM) so I can test the LLC setting for effectiveness without interference. (differential between idle and load voltage). MEDIUM seems to be the sweet spot for many gigabyte FM2/AM3+ boards as it provides the tightest regulation without surging ahead of the setting under a load like Extreme does. (a small drooping behavior is preferable under a load).

After establishing that the LLC setting selected works well, I usually under-volt at 4.0ghz a step at a time until it won't boot. It'll usually be pretty stable just ~0.0125-0.025V above where it won't boot. From *that* starting point, every +100mhz will require approximately 0.025V more to be stable... up to a point. The under-volted stability@4.0ghz will be very telling about how far the chip will be able to go.

Getting the right LLC setting is probably 90% of the battle, after that results are much better in my experience. I think this critical step gets missed in most overclocking. "medium" works well for myself any many other giga board owners I have talked to, but you may have a better result with "low" or "standard" or "auto" or "normal" or who knows wink.gif

Sorry to be a bit short on this, appreciate the help, but that is the exact steps I take when I am overclocking this chip frown.gif

Medium is definitely the sweet spot for me too, extreme over shoots it like mad tongue.gif

I can boot at 5Ghz, power settings disabled, but at 1.512v prime freezes it instantly. Knocking back down to 1.500v at 4.8Ghz will have prime running for about 10 minutes where it'll lockup the system.

Strange as these chips seem to pump out massive amounts of heat, I may have just got super unlucky with the silicon lottery frown.gif I am on the latest BIOS, tried stable and also the BETA F5B.


I'll give it more a go and see where it goes from there thumb.gif I'll try backing my RAM and CPU/NB down a bit.

Many thanks!

Hey it was worth a try wink.gif

I'm just preaching to the choir here a bit I suppose then. Sounds like you know what you are doing but just have a trash chip. That's a real bummer to be stuck at just 4.6ghz with your setup. That's one of the finest "size of a babies head" heatpipe coolers out there. Results like that are really weird IMO. Usually richland is a guaranteed 5ghz OCer, like buying an FX-9370/9590.

Thuban is still a very viable CPU. I ran an overclocked 1035T for a very long time and was happy with it. Only switched to the 8350 because I could, not because I needed to. But the 8350 is a lot faster than the 1035T was.

I still wonder how bada$$ a 32nm X8 Thuban would have been.

Thanks anyway thumb.gif yeah probably a rubbish chip frown.gif no idea will have to play around with it and go from there.

Well here's the kicker, it hits a hotter temperature than my Thuban @ 4.0Ghz hit at full load prime when it's clocked at 4.6Ghz. Something odd going on.

I would buy one without a doubt frown.gif that thing would fly. Probably would cost AMD a whack but bet a ton more people would buy one tongue.gif

Try some different software to check CPU temps. I'd almost suggest booting from a linux install image (USB thumb drive) and using that as a base from which to confirm CPU temps from if you're getting weird readings in windows.

It seems right as the BIOS reports temperatures around about right for that overclock. Also CPUz and HwInfo and monitor have been updated not long ago to support these chips. Gigabyte EasyTune6 seems to report same temperatures as well.

AMD OverDrive shows the same too which is strange. I don't know I may just have a really bad chip mad.gif booo

UPDATE: OK my 1035T is up and running.

Now this is embarrassing, 1035T at stock runs ARMA 3 butter smooth smile.gif I have a test scenario made, heavy AI so lots of physc and path finding calculations are present. My Athlon 760K at 4.6Ghz struggled, 20 FPS and very laggy. You'd have to wait for everything to pop up in the beginning as well (spawning). So either ARMA 3 really takes multi-cores well or the integer and floating point performance on this Thuban is a lot better.

Same scenario, 1035T didn't batter an eye lid. Although FRAPS reports 20 FPS on the same scenario there practically zero stuttering or "lag".

So take that ARMA 3 benchmark with a grain of salt and also fraps for that matter.


Very pleased!

EDIT: Just for comparison sake.

Athlon 760K @ 4.6Ghz, CPU/NB @ 2200Mhz, RAM @ 2133Mhz
PHII 1035T @ stock (2.6Ghz 3.1Ghz Turbo), CPU/NB @ stock (2000Mhz), RAM @ stock (1600Mhz).
