10C is a LOT!

I backed off the CPU-NB & HT link to 1.6 or so and started upping the NB and it is getting better. The GD80 can take the heat as so far the NB has not gone up 1C.

How?

Means, if you are getting temps that are 10C away from your personal temp limit, you have enough headroom to add more Vcore that will also allow you to bump a multiplier or two.

I say personal temp limit as some base their temps off 70C on Cores limit with an updated AOD. Others choose to be safer with low 60s or even lower. Both should be ideal IMO.

I ran my previous chip to the limits of temps with no ill effects even when pushing it close to 80C. That pig needs 1.6ish Vcore for 4.8. The new 8320E need 1.53ish for 5.0 GHz. And I chose stay within 65C on this one. wink.gif

Take my statement with a grain of salt. tongue.gif

How?

Taking advantage of cooler ambient temperatures I was able to add 200 mhz of stable overclock for a particular benchmark when load temperatures were reduced by 10C.

I have Proved it/tried/tested..with no picking sides intended/unbiased opinion...

I'm breaking out going back to the R2gene/920 smoking at 4.2-4.4ghz....Like seriously for a lot of the stuff I do it STILL KILLS Piledriver I'm sorry. haha

I wish it wasn't so but it kinda is...unfortunately haha

The ambients here don't vary much so that is not a factor. The only way I could see a 10C temperature drop is by building a complete other computer with lots of radiators and fans. For that much money I could buy a Titan and have better overall performance. As it is it was running at 56-57C with the odd spike to 62C.

Anyway I gave up on it and will have to get another Sabertooth to get back to 5 ghz, unless an updated GD80 comes along.

Ain't it that a GD80 runs things cooler by about 10C than most boards?

On the early 8 core Vishera's mine can run in the neighborhood of 10C cooler than my CHV-Z's do. On later chips, the difference doesn't seem to be as great.

And the fact pretty sure running the piss out of this 8320 damn near killing it with Voltage/heat etc...yes it has degraded....Yeah send me one of these new chips etc xD

I could be corrected but I don't think the new ones are that different temp-wise. I ended up lapping the chip for temps to be on par with my old chip though. 1.535 to top 62C on 30 Ambient seems to be in the same ballpark of my older chip.

Heat spreader variance maybe? rolleyes.gif

I did shoot for 80C Cores on my previous chip. I previously reported degradation but that turned out to be a placebo. It got affected much by the RAM kit I am running. Which I apparently knew when I run the new chip.

Have you ever top that? I mean no Cinebench temps too. IBT AVX MAX. tongue.gif
