It's just what happens with some chips.. never know. My 980x would do 4.4 ghz at 1.35v, 4.6 ghz at 1.45v and 4.8 at 1.5v, where as I have a drawer full of 3 spare W3520's that all of them won't even POST at less than 1.500v for vcore for 4.4 ghz, but 1.500v and they just run rock solid stable forever. I don't know if it's my board or what.

How accurate is your bios voltage settings with the terminals? My VTT reads a full 1v, in the Operating system, over what it reads at the motherboard terminal. The VTT bios setting is spot on with the terminal while others are not exact but within tolerance. Yeah you may have some burnt up capacitors or something wrong with the board. What board are you running those on?

EVGA classified x58 3-way-sli, E760.

I originally sold my 980x because I came to the realization that 6 core i7's are completely and utterly useless in all respects for gaming. Went with a high clocked quad core chip instead and been happy for years.

I've never measured this motherboard "at the points" and don't really care at this point. It's not used for daily-driving for gaming anymore, and is just happy set to what it is for years and doesn't run hot under custom water, so I don't care anymore. I just leave it alone and use it for chatting and web browsing and it's happy and everything's fine.

Take a look at Kana's benchmarks on the 6-cores.
post #5825 of 7923
I'm running an Intel X5660 in a Gigabyte GA-EX58-UD5 (rev 1.0), with 6 x 2GB Gskill 2000Mhz (F3-16000CL9-2GBRH) with an total of 12GB and at the moment I have 2 sweet spots:

1) BCLK 180
Ratio: 180x23=4.14Ghz with Turbo Boost working and stable (small peaks of 180x24= 4.32 Ghz)
QPI Clock: 6.48
Ram speed: 1800mhz (10x Multiplier)
CPU Vcore: 1.30625
QPI/VTT: 1.335
CPU PLL: 1.920
Linkpack score: 63GFlops

2) BLCK 200
Ratio: 200x21 = 4.2Ghz (I cannot estabilize with Turbo Boost, which for my MB means no x22, x23, x24 and it's limited to x21. With x24 would have 4.8Ghz)
QPI Clock: 7.2Ghz
Ram Speed: 1600Mhz (8x Multiplier)
CPU Vcore: 1.30625
QPI/VTT: 1.335
CPU PLL: 1.880
Linpack score: 52Gflops

Reading this thread over and over it looks like is a lot harder to push high ram with 12GB, 16GB, etc..

So:
1) Why is the score of linpack 20% higher with ram speed of 1800mhz instead of 1600mhz. Is it normal such a difference?
2) Which sweet spot is preferable? The BCLK 180 or BCLK 200 to run 24/7?

I did look, his benchmark results only show results on the 6 core chip. They do not show results on it compared to 4 core chips.

I sat there and owned one of the 6 core chips myself and watched task manager while gaming, I tried many many many modern AAA games at the time and none of them used more than 10% - 20% of a 6 core chip.

It's an established fact that everyone knows by now, games do not use more than 4 cpu cores for gaming. Above that is wasted. Games respond to high clock speed, not amount of cores, anything past 4 is useless. Even with a quad core i7 the hyper-threaded cores rarely ever get used for anything when playing games.

And my big computer is just for that: 90% gaming. Sometimes I may occasionally do video editing, but that's rare.. and now I do that on my x58 system and devote my 3770k only to games.

The only people that benefit from 6 core chips are those doing "work" type programs. Adobe animation rendering, 3ds max, flash player maker, maya, photoshop, etc. They're largely a useless waste for games.

Especially when we can get a 2.66 ghz, hyper-threaded quad core LGA-1366 xeon i7 (W3520) for < $10 used today, (I just looked, there's 13 of em on ebay from $7.50 - $9.99), clock it to 4+ ghz and then enjoy gaming on it. Single-socket xeons too, guaranteed to work 100% on all 1366 motherboards, oem or after-market. Compared to a 6 core i7 that costs $100 for a good one and only like 5% of games actually use the extra cores.

Quad cores for 1366 are just a lot more "bang for your buck" in general.

EDIT: Here's some data too: http://www.anandtech.com/show/2960/12

They don't overclock the 920 chips.. so most of the gains are to clock speeds, at 4.4 ghz these chips can handle nearly anything.

The only reason I updated to ivy bridge was reduced frame-time latency due to no more northbridge, personally. I only got about +20% gaming performance increase compared to x58.

Could it be that that is, perchance, a little out of date?




Studios have had a lot of time to get the hang of multicore scaling now :-)

EDIT:

"05/03/2015 at 21:53 Jeroen D Stout says:

As a developer working on a CPU-heavy game, I have to say that 4 cores are only arguably enough as a consumer-anno-2015 because most developers are not trying to use more than 4, because that is what consumers-anno-2015 are expected to have.

Yes, it is right to say often rendering is a huge bottleneck. However, when it comes to high-quality AI, high-quality physics with super-high frame-frames (some significant resonances need hundreds of steps per second), volumetric effects or large areas, things like enormous amounts of agents with non-flock behaviour (like citizens as opposed to pedestrian concepts), arbitrary crunch calculations or even just high-duty ray-tracing… then the actual argument of 4 cores is a bottleneck to future games.

Just to underline – yes, in a world where game development is mostly elaborately scripted things which need to run on outdated hardware with more GPU load than CPU, upgrading your PC to > 4 cores is probably a waste of money. I agree with this purely in the limited and depressing space of what the market is now. However, in my personal world in which games strive for interesting scenes high computational complexity, this mindset is holding back the sort of games in which which mass parallel computation could change the very boundaries of what we can do."
https://www.rockpapershotgun.com/2015/03/05/quadcore-gaming/ - [An article, rather lacking in actual substance, that]

EDIT:



Here's some terrible coding [Top work, AMD :/ ]
http://www.guru3d.com/articles-pages/rise-of-the-tomb-raider-pc-graphics-performance-benchmark-review,9.html

"I think we found a root core of the performance issues, they seem to be related to the number of CPU cores. It is mind boggling to see that with the Radeon the 1 core setup remains to be the fastest. Here you will also notice that with a 2 core processor setup we have micro-stuttering going on whereas the 1, 4 and 8 core setup are fine. After seeing this it is without doubt that AMD will need to do a thing or two with driver optimizations. "



But better from NVIDIA:


Leading to a conclusion:
"Another metric we can look at is actual CPU usage as reported by the OS, as shown above. In this case CPU usage more or less perfectly matches our earlier expectations: with DirectX 11 both the GTX 980 and R9 290X show very uneven usage with 1-2 cores doing the bulk of the work, whereas with DirectX 12 CPU usage is spread out evenly over all 4 CPU cores.

At the risk of speaking to the point that it’s redundant, what we’re seeing here is exactly why Mantle, DirectX 12, OpenGL Next, and other low-level APIs have been created. With single-threaded performance struggling to increase while GPUs continue to improve by leaps and bounds with each generation, something must be done to allow games to better spread out their rendering & submission workloads over multiple cores. The solution to that problem is to eliminate the abstraction and let the developers do it themselves through APIs like DirectX 12."

.......


And this is why I am hopeful smile.gif
