Morning all,

at the weekend im going to be adding quite a lot of parts to my PC. Got an EVGA GTX 680, a crucial M4 128 ssd, a Kuhler 620 and 16gb of G.Skill RipjawX 1600mhz ram to add as well.

Now my existing parts are an i5 750 running on an Asus P7P55D-E pre clocked by OCuK to 4 Ghz.

Do I,
a) put the ram in and turn it on and hope that the bios settings still work? or
b) wipe the cmos and start the overclocking procedure myself?

if b) are their any current guides for my hardware floating about? the stickied overclocking thread for beginners is from 2006 and I am not sure if it is still current to my hardware, and I am truly a beginner (hence why I bought the pre clocked bundle).

Thanks in advance,

Rob
 
In a stock i5 sytsem (not clocked) - if the memory is exactly the same spec as your existing memory (timings, voltage, frequency - and hopefully brand) then you should be able to just plug in the extra memory and be OK - in theory.

However, the reality is that filling all 4 slots puts extra stress on the memory controller and some settings might need tweaking - so if run into problems post back.

Also, there's a very real chance it may effect your overall clock - it may need to be reduced - but you wont know this for sure until you fit the memory and stress test it...

Note - be sure that your 'overclocked profile' is saved in the BIOS. Clearing the CMOS wont effect this - but if there isn't one saved already you will lose all your settings.

Thanks for the reply Plec. The existing 4gb of ram I am taking out, i believe its slightly slower ram that what is going in, 1333 being replaced by 1600 which my board can take.

I am beginning ot think I might be just best to set the board to default settings and try overclocking it myself, if i could get to ~ 3.5 i'd be happy and doubt id see much performance decrease?

Are these boards/chips easy to oc? any obvious settings to alter first?
 
Personally i would try the new memory with the existing setting clock - but in stages.

Take photos of your clocked BIOS settings with a digital camera and then, if required, you can adapt the clock accordingly - using the past settings as a reference.

Check your existing memory timings, voltage and then compare them to you new memorys timing and volatge when run at 1333MHz (as 12800 memory is usually clocked 10666 same as your present memory.) - the timings/volatge for the memory running at 1333MHz should be on the memory's website (they may very well be the same as your new memory).

Then put the new memory into the clocked computer and run them at the 1333MHz settings for a while and test for stability (they should be fine as technically very little has changed - and only a slight extra strain on the MCH.)

If everything seems OK after stress testing and normal 24/7 usage i would then bump up the mmeory to 1600 settings and test again.

Tweak/post back accordingly..

EDIT: Could you list your new and old memory (part number - cpuz will show this for your old memory - stickers on your ripjaws).

Just a quick tip/hint (what ever you want to call it )

With the P7P55D series....With all the ram slots populated, the board takes an age to start the post ie from when you press the power button till it displays anything on screen.

Anything that can be done to stop that happening?

Plec - will do tonight im at work at the moment, thanks for your continued help :)

No, unfortunately not.

Enabling quickboot makes no difference, It seems to be a pre-POST memory check.

an example, My P7P55D Took approx 5 seconds (from Power Button click to post screen display) with 4GB ( 2x2GB)
Now it take nearly 20 seconds with 12GB (2x2GB & 2x4GB)

The only way Ive got round it is to use "sleep" instead of shutting down

Interesting, I must admit to using sleep most of the time, but i will remember this when it comes to first power up so i don't start to worry when it dos not post fast! Cheers

@ Plec: Sorry for the delayed response, heck of a night here :/

Current ram: CMX4GX3M2A1600C9 (4GB, 2x 2GB DIMMS)

New Ram: F3-12800CL9D-8GBXL (16GB, 4x 4GB DIMMS)

Plec, Thanks again for any help you can offer
 
Yep, i would place the gSkill in @ the 1333Mhz settings that may or may not be manually input in your system already - but make sure the voltage is set at 1.5V.

If timings, frequency, voltage are all set to auto you can just install the new memory and let the computer 'automagically' set the memory to the SPD settings (1333MHz settings).

Once/if you establish it's stable at 10666 settings (1333Mhz) with your existing clock after stress testing and 24/7 everyday usage (about a week) then you could introduce the optimum settings for 1600MHz.

Use your original settings as a guide (i.e. take photos of BIOS and be sure you have a saved profile) and then work form there - post back if you run into probs.

Best of luck.
