This might help to explain

Most of the comments and questions there hit the points made and some decent info in there

I'll give 1.41 a shot and see where that gets me in RealBench. Wednesday my 3200-14 TZs get in and then the real testing starts, but I'm trying to get a good feel for the CPU / board side. Thanks for the perspectives thumb.gif

BTW I noticed Win 10 doesn't show activated if there's no internet connection rolleyes.gif. Still seems to run - in my stress test disk I usually turn ethernet off, no need for that during testing..

Can you show me where that link says anything about faster cache reduces memory accesses?

I can't tell, but it's a decent website in general... redface.gif

Now that you have pointed out the specific portion of your question about my comment i will say that no, icant. Often was the wrong word to use, maybe As Much works since less time will be spent accessing the ram, but the first sentence covered that anways.

Here is my comment corrected for you:

You spend less time accessing the ram with a faster cache, which you can see by using the MLC tool.

The cache is serving as a substitute holder of data for the memory that is faster for the CPU to access. But the speed of the cache does not affect its content. Data gets fed from the memory to the cache first time it gets accessed - what is in the cache depends of what the cpu is requesting, So faster cache does not result in less memory access, just in faster feeding from the cache to the cpu and possibly faster loading from the memory. My 2 cents ...

Has it.

Speed of cache does not determine what goes in it. Ultimately it's the programmers / application's optimizations that determines if their data can be retrieved via a cache hit, if it's a cache miss, then bummer, we now have spent an extra cycle instead of just going to RAM to fetch.

Well I tried 1.41 vcore and got 20 mins. instead of 60 so I went back to 1.405. I didn't want to up vccin to 1.90 so I figured l'd try some vccsa research. I've been using the .13 offset from my previous board which was working fairly well and had tried .14 & .12 which didn't do so well. But hey, .15 vccsa offset and I got 114 minutes. I usually do a screenshot on the half hour, but my spidey sense was tingling and I took one at 110 biggrin.gif. I guess .16 is next and see how that fares.

470 Watts! Wow! I was nervous when I saw mine above 410...

Any particular reason why you didn't want to up VCCIN?

The usual high-volt high-temp paranoia - not sure what the VRM temperament is like rolleyes.gif

And that wattage is with a lameass GPU biggrin.gif
