Intel DX58SO Motherboard

[daniel_542]

I have a really weird issue:
Intel DX58SO Motherboard.
I put 4 modules of RAM (all 1GB matching modules) and I get the 3 beeps memory error.
I take out the channel A modules (2x1GB) and the board boots
I add in channel a dimm 0 and the board powers but no POST and no beeps.
I add in channel a dimm 1 and remove channel a dimm 0 and it boots but ignores the dimm in that slot while registering the other 2.
It's core i7-920, DDR3-10600 RAM with 7-7-7-24 timings if I recall correctly.
I have cleared CMOS by removing battery and shorting the pin to reset it
I have used BIOS recovery to update to latest BIOS.
I have it on a test bench at present with a 365W PSU, ATI RADEON X600 GPU and no HDD, DVD, etc installed.
Any suggestions?

Any suggestions?

Set command rate to 2T.
If that doesn't help, then lower frequency and increase latency timings.

Can you post screenshot from CPU-Z memory and spd sections?

The auto-detect was setting it to 2t anyway. But I was going to manually clock the other RAM I have to it's correct timings in the bios and then try it with all 4 slots populated as I think it might me a minor timing issue.
I have also tried it with the modules listed in the following thread with the same issue occurring:
http://www.tomshardware.co.uk/answers/id-3437879/12gb-installed.html
1st post on there shows the CPU-Z reports for the Modules I want to run with the board.
I was going to run them as 2GB in Channel A DIMM 0, 2GB in Channel A DIMM 1, 4GB in Channel B DIMM 0 and 4GB in Channel C DIMM 0 (Triple channel board with 2 slots for primary channel).
The other thought is that I need to push the DIMM voltage up slightly to make sure the modules all get their correct power requirement (eg. 1.5V DIMM, push memory voltage to 1.55V on motherboard)

I decided lsat night to remove the CPU, clean the contacts on the CPU itself and reseat it. Once I had done this and refitted the cooler, the RAM all got recognised on automatic settings (though it's not running full speed - getting 1333 instead of 1600).
Not being very up-to-date on overclocking settings, I didn't trust myself to attempt to force the RAM to work on 1600 as there are loads of settings in the RAM timings BIOS screen that are not listed on CPU-Z or memtest86+ or AIDA64 Extreme so I don't know the correct settings, plus, I don't know where to set the bus speed for the RAM in the BIOS.

Here's a question:
Ram timings - I have 4 modules of RAM - 2x2GB and 2x4GB.
Two modules have the following timings on 800mhz: CL11, RCD11,RP11,RAS28,RC39,RFC208,RRD6,WR12,WTR6,RTP6,FAW32
The other two are identical with the exception of the RRD (which is 5) and the FAW (which is 24) - if I manually set the multiplier to kick my RAM to their full speed, which timings should I use for stability? There obviously isn't an issue running these modules together in the board I have or I would have had major issues since getting windows running and memtest86+ would have given errors when I ran it.
I just want to know for when I set the RAM up to run full speed. Thanks

CL11, RCD11,RP11,RAS28,RC39,RFC208,RRD6,WR12,WTR6,RTP6,FAW32

This is not really readable.
Cant you post screenshots from CPU-Z?

see 1st post from thread: http://www.tomshardware.co.uk/answers/id-3437879/12gb-installed.html
But the issue is not the settings it displays there.

My BIOS not only needs those settings, it requires all of the settings displayed in the 8th image down this page: http://www.pcgamer.com/ultimate-bios-guide-every-setting-decrypted-and-explained/4/

The issue is that while most of the settings for my 2 pairs of modules are an identical match, two of them don't match.

The RRD on one pair is 6, on the other pair it is 5.

The FAW on one pair is 32, on the other pair it is 24

All other values are an exact match. I do not have the ability to manually set some values and leave others on Auto, if I set my RAM to override timings and speed, I have to set ALL of these values manually.

I just want to know which is the safer value to use when manually setting up the RAM in my BIOS screens?

When you have to input ram settings manually and modules have different spd values, use higher ones.

BTW - your motherboard is triple channel. You should be using 3 matched modules in blue ram slots.
Quote from manual:

Installing memory in Channel A, DIMM 1 may result in less than optimal memory performance.

Thank you for the info mate. Its helped me loads. I spoke to intel the other day and they said that as long as the total ram in each channel is a match, it will perform triple channel without any issues. So i have 2x2gb in channel a and 4gb each in b & c. It works a treat except the lack of the 1600 support lol
I assume that if i bump up multiplier another 2 and adjust timings correctly, i should get the proper speeds?

Yes, it should be possible.
But - it will also require manual tinkering with ram settings in BIOS (as overclocking usually requires that).
Note - don't go higher than 1.65v on ram voltage, as that will cause damage to the cpu.

Im not actually intending to OVERCLOCK the ram, just run it at its actual speed... Its 1600 ram currently running 1333. I was going to bump it to 1600 with its correct timings. Hence the questions.
Lol
Thanks, i will let you know how i get on

On that motherboard ram frequencies 1333 and beyond - all are considered overclocking.
Quote from manual:

DDR3 1333 or higher memory support on this desktop board requires
compatible XMP-enabled memory or advanced knowledge of BIOS and
manual memory tuning. Individual results may vary.

Well, bios wont accept my ram running 1600 on present setup (annoying but acceptable). Still on a positive note, it is running and i cant complain lol
Thanks everyone.
