ASUS Maximus III GENE - BCLK help please! :)

[Guest TheMadDutchDude]

Hey HWBot forumites,

 

I'm trying to get my board stable with a little i3 530 for now and I'm running into issues. This board will be used for many other CPUs but I am starting off with this one due to budget reasons.

 

I've got 225 BCLK stable with a low RAM speed (1350MHz) and the CPU is on a 13x multi. I'm doing this to avoid any speed related issues as I am running on a stock cooler for now until something more substantial turns up in the post next week. Temperatures are not an issue as far as I am aware due to the low clock speeds, but I do realise that it *should* perform better under the cold stuff... I can't get the RAM to run with a 1:8 ratio which it should manage without an issue I would've thought.

 

Anyway, I was wondering if you lovely lot would be able to help me to achieve my 1600MHz + RAM as it is pathetic running at 1300MHz when I have a 2200MHz 7-9-7 capable set of RAM. It is a set of G.SKILL RipJaws 1600MHz 7-7-7-24 with BBSE RAM chips I believe. Tested previously by my K404 so I know they're capable.

 

My settings are as follows:

 

CPU Ratio: 13x

BCLK: 225MHz

DRAM: 1350MHz (1:6) - looking for 1:8

QPI Frequency: 5401MHz

 

(I've never messed with these, I need to learn what they do!)

CPU Clock Amplitude: Auto

PCH Clock Amplitude: Auto

CPU Clock Skew: Auto

PCH Clock Skew: Auto

 

Full Phase Control: Full Phase

Load-Line Calibration: Enabled

CPU Voltage: 1.25v

CPU PLL Voltage: 1.7v (tried between 1.6 and 1.8)

IMC Voltage: 1.325v (all the way up to 1.55v)

PCH Voltage: 1.18v

 

Can anyone offer any assistance here?

you QPI Frequency is to high use slow mode for 2D benchmarks

[Guest TheMadDutchDude]

BUMP.

 

Can anyone shed some light on this?

 

I've searched everywhere and cannot find the slow function. I don't think that it is on this board. I've never even heard of it.

[Massman]

You should lower the QPI frequency. 5300 on air is already quite high. There is a QPI frequency option in the BIOS.

[zzolio]

slow mode should be in the same option as QPI frequency

[T.Rex]

make your qpi freq about 5000mhz then you have no problems at this area on air

[Guest TheMadDutchDude]

Thanks for the replies guys. Sorry about forgetting about this one!

 

I've managed to get a different CPU now and it seems to work a bit better. I've not hit the FSB wall yet but it does run with a full multi and does much higher on the RAM too. I think the 530 was a duff chip.

 

I will report back if I get stuck again. I'm still looking for the slow QPI setting though!

[basco]

should be in the qpi frequenzy menu.

[Guest TheMadDutchDude]

There sure is, Basco. However, there's no "slow mode" unless I am looking for the wrong thing. I've chosen the lowest multi (4800MHz @200BCLK) but it can't go lower than that.

[Massman]

Hm, they removed the option?

[Guest TheMadDutchDude]

Possibly. Either way, the 530 was a dud chip. I got a 550 to replace it with and it flew to 240 BCLK without stopping which meant the QPI was at around 6000MHz before it hit a wall. I think it needs cold to get higher than that.

[CL3P20]

X58 has slow mode.. the 1156skt does not..

 

*if your clocking 1156.. you will need to keep secondary and tertiary timings loose for IMC as you scale bclk up. With decent memory and cold, you should see +250bclk.

[Guest TheMadDutchDude]

Thank you for that, CL! I will be getting this chip cold soon hopefully. I need to buy a few others to make it worthwhile first, though.
