Asrock Z77 OC Formula Overclocking / troubleshooting/ Discussion - Page 39

post #381 of 1118
Please for the LOVE of GOD I've been trying to get these memory sticks to post @ 2800 for about 10 hours now. The highest I can get them to post with no problems is 2200 Mhz @ 11 - 13 - 13 - 35 2N

I'm using i5 3570K if that has anything to do with why I can't get these to post at their rated factory speed of 2800.

I'm running platinums at 2400 no problem.

Not all cpu are built the same and not all of them have an imc capable of running 2800. It could be that yours is not up to the task. I've ran my 2600mhz rated sticks at 2800 on the OC formula.

Is there any other way to know if my CPU is my bottleneck?
post #386 of 1118
There is only one way to find out. That is by gradually increasing clocks until you can go no further. But you'd still have to know if it's a memory issue, imc, or voltage issue somewhere. I've had several 3770k that could do just slightly over 2800, some that did less and one 3570 that did over 3000.

Hi again .. Here in Bulgaria is Sunny and today i will test the machine as i promise with the settings that you guyz gived to me.

1. I load default settings from the BIOS. Then used the CLR CMOS Button for sure.
2. I Chouse Stage 3 From the NickShin's OC Menu at 4200MHz and a fixed voltage has set
3. I Load XMP Profile 1.3 (i dont set the Speed yet) and set the Timings like : 9-11-10-27-2 (Memory Performance Level Auto)
4.I Changed the DRAM Voltage from 1.505V to 1.720V
5.I Changed the VCSSA Voltage from 0.928V to 1.193V
6.I Changed the tRRSR from 4 to 5
7.i Chouse DDR3-2133 from the DRAM Frequency menu and save and quit

The machine turns off emidiatly and start after 2 sec. with no screen and thats it .. after 3 attemps it turns on and shows 1333MHz at the DRAM Frequency mad.gif

Any suggestion ?

p.p. When i chouse Frequency 1866 , the machine start normaly but its not the speed that i want , because my ram sticks provide 2133MHz OC.


Any suggestions are welcome!

I have a question for you guys. will the EK-FC Bridge DUAL Parallel be able to bridge the distance between the first 2 pci-e slots? or do I have to get the triple bridge?
