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

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.

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

slow mode should be in the same option as QPI frequency

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

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!

should be in the qpi frequenzy menu.

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.

Hm, they removed the option?

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.

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.

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.
