PC Peripherals Query on DDR3 Memory

@OP:

Not sure what exactly Lavalys shows in terms of SPD. But pick it from CPU-Z for the speed you want 'em at.
 
Does this help?

Sure brings assurance to the mix...! :)

Just map it as per XMP @ 1.650V. Though first leave the voltage at auto, as Bottle mentioned. He has direct experience with your chip set.

I never worked with an AMD build, but just citing examples from my experiences, since RAM extended profiling is not that different to an Intel.

setting the multiplier alone to 8 (memory clock) is enough but it runs the memory at a more relaxed timing than what it is specced for. The giga bios had the spd values to the right of the settings under DRAM config so you just had to look at that and enter the same values

voltage can be left to auto, works fine

Just to sum things up:

1. Memory Clock (Mx): Set to .8 for 1600Mhz
2. DRAM config: 9-9-9-24
3. DRAM Voltage: Auto

Do correct me if I'm wrong here. :)
 
These are the settings I use, all you need to do is match it with the SPD column on the right. by default it has the values from the auto column

Guys, got my second pair of XM3s today...

What I did:

1. Multiplier set to .8
2. DRAM configuration as per SPD values.
3. Voltage config: Auto

My only concern is that the sticks are currently running at 1.6V (BIOS).

Would appreciate your inputs here.

TIA!

If it passes the stability tests then you are fine. Run some Prime95 threads or MaxPI. Else if you do not game, try your usual computer usage, if stable -- done.

Haven't tried any games yet. That apart, the system is doing just fine (stable). (TW)

A little apprehensive about the running the stress tests (Prime95). :ashamed:

One other question: The bank cycle rate (tRC) value in the XMP profile of the RAM states 41 for 1600 Mhz, while the SPD value in the BIOS showed 34 (which is what I've set). Does this make any difference?

Thanks.

I usually go by the SPD setting in CPU-Z. Not BIOS.

See a stress test will not burn out your system. It is not high OC'ed at all. Just sit there and watch, and keep an eye on a CoreTEMP instance..! (This is just for the 'sleep well at night' factor).

You seem to be fine, though.
 
^ Ok, I just finished carrying out a couple of tests using MaxPI and Prime95 (short period :P) and everything seems to be fine. (TW)

The only niggling concerns are the right tRC value and the current voltage of 1.6V. I will try to look into this a little more, as I don't want any surprises in the future.

It should be fine at 1.6, is there any particular reason you are worried ? I think DDR3 should be ok upto 1.9V

Even the corsair page says that it has been tested at 1.65v XMS3

tRAS, tRCD, tRP, tRC ? | techPowerUp old link but it says tRC = tRAS + tRP so by that logic 34 or 33 should be fine.

Edit - Nothing wrong stress testing, better something fails now than in the middle of something important. Download OCCT and let it run for an hour. At the end it spits out some graphs showing voltage fluctuation and such which is worth looking at once. If its fine, you can relax

The motherboard's specs. rate them at 1.5V, so I figured mem. modules must run at this voltage for long term reliability?

but it says tRC = tRAS + tRP so by that logic 34 or 33 should be fine.

By that logic, it sure is alright. Although, the JDEC(XMP) profile in CPU-Z shows 41, which got me thinking.

As mentioned above, I've carried out a few. By OCCT, you mean this?
 
^ yea thats the one, that and memtest should be pretty much ok, though I think you shouldnt be worried or need to stress test anything when you are running everything at their rated spec.

I think the bump from 1.5 to 1.6v is pretty minor. Even at 1.9 or 2.0 you theoretically should get many years out of them :P so don't worry (Unless you plan to use the rig for say 15 years)
 
That certainly is reassuring, thanks. :)

Also, gave OCCT a whirl (10mins). Quite intense, compared to the other tests I carried out, as the core temp was hovering between 58.5 ~ 60.5 at Full load.

Thanks again for all your inputs!
