Problem with procesor in 3dmark 11 in Celvo p370sm

Hi I have problem with low physics score in 3dmark 11. I turned off programs, antyvirus etc. nad it's help a little. It's not problem with throttling, because i have something about 75-77 after 2-3x 3dmark 11,

NVIDIA GeForce GTX 780M video card benchmark result - Intel Core i7-4800MQ,Notebook P370SM

 

possible Cpu Parking , try Coder Bag: Disable CPU Core Parking Utility

 

Easier solution... upgrade to Windows 8

 

he already on 8.1

 

Ah yeah, my bad... Mondays arent good for my attention to detail lol :/

 

Perhaps single channel DDR3 RAM impacts the score...

 

That will be the one, 3dmark 11 likes ram bandwidth anyway but performance will tank if you go below a certain point.

 

Does single channel ram could have so much impact on the score( overk 1k). I have tested processor with cinebench and i've got better score than i7 4700mg so its's not processor fault. Maybe change ram in diffrent slot could help? I have no idea rly

 

Some CPU benchmarks rely heavily on CPU alone, others rely on the CPU+RAM subsystem. Apparently Cinebench belongs to the first group, while 3DMark11 belongs to the second one. Don't take it for granted though, I'm just speculating.

Putting RAM in a different slot will not change anything, only adding one more (or three more) modules will make the IMC and RAM work in dual channel mode, effectively doubling the RAM throughput.

 

If he adds 3 more wouldn't it run in quad mode?

Quad channel memory controller is integrated only in LGA2011 Intel CPUs. If he added 3 more modules (so there would be 4 in total), the memory would work in dual channel interleaved mode.

 

So its not supported in latest Haswell boards?

 

AFAIK there are no Haswell CPUs for LGA2011 yet, so no.

 

Hmm ok, thought someone mentioned it works but guess not. :S

 

Well, the LGA2011 i7-4xxx CPU series is based on Ivy Bridge cores, Haswells for this platform aren't out on the market yet. LGA2011 is the only Intel (consumer) platform supporting quad channel RAM, LGA1366 supported triple channel RAM, all the other Intel platforms out there (excluding Atoms - some of them have only single channel IMC) are/were dual channel.

 

Nevermind.-

 

Yes on the 9570 you can get quad channel due to the x79 chipset and 2011 CPU, all other machines (except for the x7200) will be dual channel max and any 4 dimm setups will have 2 dimms sharing each channel.

 

My P170SM got P7854, with 780M, and i7-4800MQ, 16GB RAM in two sticks. That was straight out of the box, no av, no tweaking, etc. Now I need to check to see if that is good for stock.

 

So does the 9380 have quad channel as well then?

The 9380 neither uses an X79 chipset or 2011 socket CPU so no, as I said ALL others except for the P570WM and X7200 (which uses tri-channel) will use dual channel as a maximum. That goes for every other notebook in existence, not just sager/clevo machines.

 

I would run something like XTU or anything that will let you see the loading of both the cores and threads. I'd be interested to see what's going on there.

Also - thought it shouldn't be necessary, something like XTU helped my 3DMark11 score. (The one in my sig!)

 

Okay, gotcha!
