3570K, D3H and Crucial Ballistix Tactical Tracer

Hi 8 Pack,

I have the above setup with 4GB of ram. I've done some basic overclocking with it so far as I've only had the stock intel cooler.

With getting my (unfortunately) faulty H80i the other day I was looking in on how to push the system further with the CPU being under water.

I've managed as far as 3.8Ghz on 1.225V and the ram running at 1600Mhz at 1.5V (basically xmp spec)

If you could provide some tips to get it a bit higher ready for when a new H80i turns up i would appreaciate it

Cheers

Just continue in the current vain mate.

You should be able to get 4.2-4.4 without many problems.

Will give it a go when the cooler comes back.

I've managed to get the ram at 2133mhz stable at 1.65v, will changing the timings make any difference?

Cheers

Yes timings do make a difference to teh overall performance and efficientcy of a system.

Does the ram I have respond well to overclocking or is upping the frequency about the limit?

8 Pack · 27 Jan 2013 at 15:06

Not sure!! There are many types of Ballistix around. What is teh stock timings at 2133???

Simon_89 · 27 Jan 2013 at 22:46

That's CPU-tweaker

The ram is at 2133 @ 1.6v

8 Pack · 28 Jan 2013 at 20:04

OK the initial tuning is 1T command rate and trfc 148, 127,121,114 try each in turn. Then try tFAW 26.

Simon_89 · 30 Jan 2013 at 14:46

Putting the ram tuning aside.

I've fitted my H80i and ran the overclock up to 4.5Ghz and put inter burn test on and even though the system appears to be fine the test stops on the 2nd run saying it isn't stable.

Any ideas why?

8 Pack · 30 Jan 2013 at 16:08

because its not stable!!! Add Vcore, VCCSA, VCCIO or IMC volts and re-test!!! For me IBT is a terrible test. Even intels engineers think so. Prime blend for like 20 mins is enough then use your PC. Using your PC proves its stable for what you need it for.

Simon_89 · 31 Jan 2013 at 07:56

Well I've decided to start over again so I know what I've changed.

At the moment the only thing I've touched is the multiplier to 40 to achieve a 4.0Ghz clock speed and Prime95 ran fine without any issues.

Guess on my 4.5Ghz efforts something else was needed as it BSOD just shortly after Prime started lol

8 Pack · 31 Jan 2013 at 10:00

Voltage probably!!!!

Simon_89 · 31 Jan 2013 at 14:12

Could you recommend some setting to have it running at 4.5Ghz?

8 Pack · 31 Jan 2013 at 14:50

Each chip is different mate. So you must test!!!

Some do 4.6 at stock some will not do it at all. I would say 4.5 avg Vcore required is 1.275v-1.3 with current steppings. With IMC volts at 1.05v

I will give it a go when I get home from work.

What does PLL do? I seem this mentioned quite often

8 Pack · 1 Feb 2013 at 11:36

PLL is Phase Lock Loop. Essentially its clock generator error correction and lock on. For us as clockers Ivy CPU like around 1.65v or 1.9v try both ends of teh spectrum and find what your CPU likes assists DRAM overclocking, CPU clocking and BLK clocking.
