Hello,
I want to add another 8Gb to my system, I have this in it G.Skill RipJawsX 8GB at the moment (https://www.overclockers.co.uk/showproduct.php?prodid=MY-060-GS).
Should I choose this so it's all matched or use the Team Group elite RAM (https://www.overclockers.co.uk/showproduct.php?prodid=MY-020-TG&groupid=701&catid=8&subcat=1517) thats a little bit cheeper?
The timings are a bit better on the G.Skill but currently there is no overclock on the 2500k although I might well o/c it in the future.
The heat sinks are an is as I'm using a Antex water cooler for my CPU.

It won't make a huge difference bar in appearance, the timings on the G.Skill will likely default to the looser Team Group ones, but nothing you'd notice in real world usage. Just memtest86+ them after installation to make sure everything is working error free.
 
Shouldn't be, you can always force the timings to be the same speed in the BIOS settings if the motherboard doesn't do it automatically.

With Sandy Bridge the memory speed isn't linked to the CPU speed like it was on previous generations, so no problems no as they are separate.
 
What is your system mate?? Then we could advise better.

The GSKILL are better modules for sure Cas 11 is very loose at 1600mhz.
 
I'm glad you said that, I ordered the GSkill RAM yesterday.
Will be going in:
Intel Core i5-2500K @ 4.0GHz
HIS 6870 IceQ 1028Mb
Gigabyte Z68AP-D3 Intel Z68
BeQuiet Pure Power L8 630W
G.Skill RipJawsX 8GB (2x4GB) DDR3 1600MHz Dual Channel
Antec Kúhler H2O 620

The o/c has only been done by upping the multiplier, nothing else has been changed.
 
Well it's here and will go in when I get home.
Should I set the timings on the RAM in the BIOS or leave at auto?
Or should I go for different ones to the ones specced?
 
I'd leave it for now, boot into Windows and use CPU-Z to see what timings its running.

Then of course run Memtest86+ if the timings are correct.
 
Hiya, got it in and shown in CPUz, however the timings are 9-9-9-24 under something call JEDEC1 but the frequency is well below 800MHz (which I think it should be as it 1600MHz RAM). JEDEC5 has 800MHz and 9-9-9-25 timing.
There are a couple other JEDEC entries too.
Is this correct?
 
Got some pics done now:

Bit puzzled with the spped tab show different info to the memory tab though.

Can't see larger versions of the first two images, however the third image with the memory tab shows the modules current speed and timings. 800MHz = 1600MHz and the timings are 11-11-11-28 which is to be expected.

I'd run Memtest86+ on the lot (can be done from a USB stick) for 2 passes. Could take quite a few hours though so just do it when you are not using the system.

JEDEC profiles are basically standardized timings built into the modules that the motherboard uses to set the timings and voltage based on the speed they are running at.
 
The links below each pic go to my photobucket where they are hosted, and are too small there as well! Can send you a dropbox link if that helps?

Is 11-11-11-28 correct? The description of the RAM on the pack and webpage shows 9-9-9-24.
The difference could be my understanding!
Will run memtest over night.

If the second set was the Team Group set you purchased then the timings are correct, it defaults to the slower set.
 
Try forcing the timings to what is on the side of the stick in the BIOS.

It will show the timings in memtest86+ when you run it.
 
Set the timing in the BIOS, but now have to work out the speed settings as it is showing as 1557MHz, but I guess 50Mhz isn't going to make any noticable difference.
With the timings correct and speed almost correct I've left it running memtest for the day.
