Memory fault?

Teaboy · 1 Jan 2010 at 13:46

I bought the G.Skill Trident "Low Latency" 6GB (3x2GB) DDR3 PC3-12800C6 1600MHz Triple Channel Kit (F3-12800CL6T-6GBTD) which arrived yesterday with my X58A-UD7 board, and I think the memory might be faulty.

GTA4 keeps crashing, but it seems to be happening to everyone, but I don't have any other games lying around to test other than Source based games, and they run fine. Half-Life 2 runs at 500fps, which is the maximum I set. I do have a Dirt2 voucher, I'll look into that.

The memory works on these settings, but occassionally only 4gb is detected.

When I select "Profile1", the BIOS then finds all of the values specified on the packet; i.e. 1600MHz and 6-7-6-18, but the system will refused to boot.

I've turned off all the Intel overclocking stuff, so my 920 D0 processor is running at 2.66GHz.

voltage is showing at 1.6 when on the XMP profile. Set it manually to 1.65 as per spec.

How odd. My packet says 1.6v

But this guy has the same memory and his says 1.65v:

I'll give it a go at 1.65v.

Apologies for that, i checked up the spec online before posting and arrived at the same review you did for the 1.65v

Checked g skill site, they suggest 1.6v aswell - http://www.gskill.com/products.php?index=186

Might be worth running memtest on them on the xmp profile - http://www.memtest86.com/

I tried at 1.64v and 1.66v (only available options) and neither worked.

I can't run Memtest on the XMP profile because when it is enabled the machine won't even post.

I don't think that version of Memtest will work on my machine anyway

memtest should work, it runs after the bios so before windows loads.

Try running memtest on a profile that works. 1 run is okay but i suggest 3-4 to be sure.

I meant that Memtest+ works better for quad cores. And the machine doesn't even post, so it's impossible to run anything.

yep, that is does, Run it on the memory anyway at any speed you can get it to work at just to see if there is any faults.

I tried to use the XMP profile but I lowered the bus speed to 1333 MHz. When I ran Memtest+ I noticed that it was running at 6-6-5-19, which is clearly not the settings in the profile. I double checked in CPU-Z and that is also showing 6-6-5-19.

So I think the fault is with the motherboard, which is probably a BIOS error. It appears to be using the wrong settings. I think I'll have to set them all manually.
