And after all that you can still gain speed by exercising the muscles in your mouse hand and mouse arm in the gym.

I already got enough hate for doing this, please stop.
It's my business how I spend my money.

actually if it works i would be impressed to see the new benchmarks just watch your fan on the mini if it does the constant on issue then the memory you have is too high of a bus speed for the mini to handle

But this should be interesting please keep up in the loop here at 123macmini.com we would really like to know i am really curious

I will post continuously in all three sites this thread is running at, I get really good inputs from all angles (and a good part hate also) but that will not let me stop Smile

I am currently downloading Photoshop CS6 trial, anyone have a good bench test to run in that?

I have been running benchmarks most of today but decided to make them into comparison graphs to cut down on the amount of stills added to the thread.

Will post them when I have ran more benchs.

Just installed the 16GB DDR3 1600MHz right now and will over night run a couple of Rember tests to see if they work as expected.
Can though already tell that they DO run 1600MHz even in a Mac Mini, the auto overclock thingy seems to work.

I was running Rember memory test over night and when I came to check on it this morning I found an error that looked like this:

Quote:
Test sequence 3 of 3:

Running tests on full 14605MB region...
Stuck Address : setting 1 of 16 ok
Linear PRN : setting 1 of 16 ok
Running comparison tests using 7302MB buffers...
Random Value : \ 

FAILURE! Data mismatch at local BUFA address 0x000000014606fcd8, BUFB address 0x000000030e707cd8
BUFA Data: 0x7af6956ecffd55d0, BUFB Data: 0x7af7956ecffd55d0


Ran another memory test in Tech Tool Pro-To-Go and found no error there after 15 minutes run.

I'm thinking it must have been a heating problem? The mm fan was spinning like crazy when it ran Rember...

okay it ran 2 full passes for a few hours and on the third pass it failed?

rembr ramtest runs hot as it fully tests all of the ram.

Sounds like the ram got too hot.

I hope it was not cooked.

Been there done that.

2011 minis run hot and loud when pushed.

I use a laptop fan under them for cooling. I will post a few pictures on mac rumors later today.

The machine you have runs very hot.

I got rid of mine and used the servers instead.

I now got rid of the servers and have 2 base 2011 models and 2 base

2010 models.



I also have the new pc I built a real beast. far superior to the mini in every way but one size it is
freaking huge.

Yep, that's exactly what it did.

Have been running 10 more Rember laps today and again in lap 10 out of 10 I got the exact same error as posted before.

I will receive my 8GB DDR1866 Kingston PnP kit on monday, so will bench the 16GB over the weekend and wait and see if the 8GB kit does it close or better to these (because of the faster speed).
If it's close or better then I will try to return the Corsair for refund.

My guess is that it's just a heat issue not an actual fault.

Just updated my Flickr with pictures from the past two days tests.
Not actual benchmark tests, but more from when I fittet the RAM and swapped the HDD in my external G-Drive to one of the SSDs. Making it ready to be cloned off the Mac Mini HDD.



Check out the gallery for the whole story

I would love to have one of those 240GB Intel SSD's. That alone will make your Mac mini speed along like a little demon. As for RAM, isn't there a tipping point of CAS latency versus clock speed? I've read that the difference with using DDR3 1333 versus DDR3-1600 with Sandy Bridge is actually minimal at best. Once you get over that, there is little to no benefit. Especially when you look out at what you are spending for the faster RAM.

Either way, I commend you on the testing! Forget about the negative people out there.

Been benching a lot today and found some interesting details I will share later on. I think you are right about something there with the RAM, the HDD is atm a HUGE bottleneck in the system, but it gives me a better chance to see what difference RAM can make.

-----

A new question came up during todays benching:

What geekbench score is the mark to beat on this model in os x lion?

Thought it was a question of more broad interest so gave it it's own thread

NovaBench:



Faster RAM speed + more RAM = higher score.
Will have to see what the Kingston PnP 1866 gives because it's only half the size but even faster speed.


GeekBench:



Memory performance a little bit higher, mostly due to RAM speed I guess, but will see that when I have the Kingston PnP number because they are even faster.
Memory bandwidth gives a BIG difference, my guess is due to the much bigger memory size, 4GB vs 16GB. 8GB numbers should land somewhere in between.


Lloyd Photoshop benchmark:



Photoshop CS6 is a really memory hungry app, swallows the 16GB like candy but also gives a HUGE speed difference.
Will wait to see if it's only speed as in RAM speed or if amount also makes a difference.
Maybe I will give Corsair ValueRAM 2x8GB DDR1333 a shot also to conclude wich factor is most important.


Rumors about faster RAM gives a FPS improvement is something I have not seen. Been testing with Duke Nukem Forever and a screen recording app that shows average fps recorded, numbers were pretty close.
Also file transfer speed is not any second better, will have to wait and see what happens when I install my SSDs.


More pictures from these tests can be found @flickr

A funny fact by the way, my boot times from I push the button til it auto logins and I see the desktop is with the 16GB RAM 1.5 seconds slower than the stock 4GB...

Have testet it several times and it's consistent.

On the other hand, boot to login screen is pretty much the same, average 0.2 seconds quicker.

Just installed my new Kingston HyperX PnP 1867MHz DDR3 2x4GB kit.

Am going to Rember test them the next few hours to see if they work as expected before benching anything.

Am thinking about if I have damaged my SSDs and original Apple RAM because I have placed them next to my small desktop speakers with 4" midrange?
Can the magnetic field from the speaker do anything bad to RAM or SSDs?
Just a thought, have not tested them or anything but moved them further away just in case it was a bad place to put them...
