My gigabyte board has been swapped for a new one smile.gif

Would it be better to use my amd 8350 with an asus sabertooth 990fx rv2 as my main machine or

my i5 4670k with gigabyte GA-Z87X-UD3H

Depends on what you are doing with it.

well, perhaps.

so why does this happen though? i wonder if there is something that i'm doing or not doing that is causing this behavior. perhaps because i have all the power saving features turned ON? could they cause something like this to happen? maybe some power delivery setting?

could it be some other component in the PC? RAM perhaps? but I've checked them with memtest. doesn't see there is anything wrong with them.

or a fault in mobo? the motherboard temps reported in AISuite III are in the low 30's. i don't know whether they are VRM temps or some other place nobody cares about. but reviews seem to suggest the Hero's VRM sinks are pretty cool to touch.

it is definitely not the ambient temps, because the day those tests failed was fairly cooler than the day OCCT passed.

so, now my method of stress testing has gone from 6hrs OCCT stable to 6Hrs OCCT table on 3 different days. gah i hate Haswell. my SNB chip wasn't a super clocker, that's why I'm not regretting the switch that much.

any clues?

on another note, i did a test to see how cache ratio affects core overclock, but i am afraid to talk about those results because they can be different today! anyways, what i did was, i set the core voltage to a value that would cause prime95 to BSOD . and i tried all the cache voltages from 1.05V to 1.21V to see if different cache voltages would make prime run for longer. cache ratio was set to x35.

at most volts, it would fail within a couple of minutes. but at 1.10, 1.11, 1.18, 1.19, 1.20V, it would go on for about 8-9 minutes before crashing. at 1.19 i got a clock watchdog timer BSOD (0x101?) instead of the regular 0x124 i got for all other settings.

thing is, the results were fairly reproducible. i don't know if these results would change if you change any of the other settings. it could be my weird chip though. unless someone else can confirm this, take it with a grain of salt.

If you're gaming, then the 4670k will be slightly better. Especially overclocked. However for rendering and things like that, the 8350 would be better. Why did you buy both?

Quite simple, the misses has an i3 2120 and it was time for an upgrade

I think part of the reason for the inconsistency may be temps. I've noticed that I can pass in the evening but the same settings fail the next afternoon even if the core temp is only a few (2-3) degrees higher (the ambients are quite a bit higher though). So my theory is that either something on the motherboard is getting hot and causing problems, or some part of the chip (possibly the FIVR?) is very temp sensitive and fails with even a small change. Other people have said they haven't seen the same behavior though, so who knows. Maybe it's just always kind of unstable, and it's just luck of the draw.

thing is, the ambient was cooler on the day that it failed + it was the night. i passed 8hrs while i was at work.

guess that's why you have to run stress tests for 24hrs to call it stable. well, i don't care anymore. i did a 14hr H.264 queue, and it didn't crash. i'm gonna keep this 4.4GHz/1.290V and see if i ever crash with those settings. but i did set the cache voltage to 1.18V because that seemed to be the sweet spot for whatever reason.

i feel like changing the RAM and see if that fixes the probs. even if memtest passes, that doesn't really mean that the memory is "compatible" with the mobo. thinking of getting the Crucial Tactical LP 1600 16GB CL8 1.35v sticks as they are way cheaper (about $140) than those 2133MHz and up RAM over here. about $50 cheaper than the cheapest 2133 sticks.

The rumor part was about Broadwell not being a socket chip for desktops.

In regards to temps from what I saw, no major correlation between instability and moderate temps. Moderate being under 85C peak. Stockfish chess was causing bsods in 10-20 minutes, it was ridiculous.

Hello Guys,

If you need a good guide to get stable use this one, helped me to get stable and he got some good reference points to start with.

I followed his guide step by step.

Thanks ProKoN!
