If Ram Runs Fine Should I Increase The Voltage To Stock?

You might be able to run it at 1.8V at default settings, e.g. all auto in BIOS.

If you want to tighten the timings to 4-4-4-12, you might have to increase it to something higher, perhaps even the rated 2.2V.

IMHO, you should use the minimum voltage that the system can run in a stable manner.
If 1.8V is is enough, you are fine.

I will double check the timings when I get home
 
Mine (Crucial Ballistix LED) curently runs at 950mhz @ 5-5-5-15, Vdim = 2.1v.
My eVGA mobo does not support Vmem at 2.2v so I'm pretty much hosed at 950ish mhz or so.
With 2.2v these rams should go way past the 1350 threshold as I was told by Crucial tech support.
 
it's all luck. Your motherboard and BIOS revision have a huge role in how overclockable at a certain voltage your memory is. Sometimes 1.8v is fine, sometimes you need 2.0

wow

so if I tweak the settings this ram could go that high?


I still need to run memtest again, I had the ram accidentally underclocked when I ran it last time.

I now have it set at it's rated speed and timings

How true!
My eVGA mobo only supports Vdim 2.1 max and my rams need 2.2v.
The differences are substantial, 200-400mhz in speed.
I maxed out @ 1000mhz at 2.1v where some other mobos that support 2.2v vdim have these rams maxed out at 1350 or higher.

Along these lines (and please keep in mind I'm a rookie with this stuff)... I have the same Ballistix ram sticks that run at 2.2v and I hope to put them in a system with a Gigabyte GA-M57SLI-4 mobo with an AMD X2 5600+ processor. Both mobo and CPU manuals recommend ram at 1.8v (though the mobo manual suggests I could increase the "normal" (default?) voltage by between .025 and .70 volts). The Crucial website matched this mobo with the 2.2v ram. I'm afraid I may have purchased the wrong memory sticks.

My question is this: will using this 2.2v memory cause any harm to my mobo or CPU? Or will the ram simply run at the default voltage of the board (1.8v) unless I jack it up via a BIOS modification? And if I do jack it up to 2.2v, will THAT cause problems with my mobo or CPU?

Note: I'm not necessarily into overclocking, so that's not a big consideration for me. I just don't want the system to blow up when I plug it in.

Thanks in advance!!!



 
Running your RAM at 2.2V will not cause any damage to the motherboard.

If anything, it might damage the RAM module itself, but since it is rated at 2.2V by Crucial, and it has their Lifetime Warranty, there is nothing to worry about.

Most of the motherboards are rated at 1.8V, unless/until you change it manually in BIOS. Some MB's might have problems booting the first time, since the default voltage is 1.8V, until the voltage is changed in BIOS. But most of RAM SPD's are programmed with 1.8V in mind, and often the timings relaxed to 5-5-5-15 and/or frequency to 667MHz or lower.

That's why it is imperative that you do all the settings manually (800MHz, 4-4-4-12-2T, 2.2V).

The worst that can happen is that you won't be able to boot the first time.

Just put a different stick of RAM rated for 1.8V into the memory slot, enter the BIOS, change the settings, EXIT and SAVE, and then shut off the computer on reboot, change the RAM to Ballistix, and turn the computer back on.

Good luck!
 
What about the CPU recommended RAM voltages? AMD says 1.8v is the recommended voltage. Will running RAM at 2.2v cause problems with the processor?

Thanks!

No, that is just the rated startup value. WHen you change it to 2.2v it will be fine.
 
Thanks very much folks, you've eased my mind here. Once I get this thing fully assembled and fired up, I'll give an update.

I got my Ballistix to their rated 800MHz 4-4-4-12 on the mobo default 1.8v

Does that mean these should oc really well with more voltage?
or does that not mean anything?

Means nothing. Try memtest, I wonder if you can startup but would get errors if you test it.
 
As cmdrdredd, run the memtest.

If all is fine (no errors), run Orthos in Windows.

If that checks out fine, leave it alone at 1.8V.

Believe me, you'll know when/if the computer is unstable...

If you experience lock-ups, crashes and BSOD's, it will most likely be RAM undervoltage related.

But if it runs fine, you have just increased the longevity of your components. You should always run the components (CPU, RAM, NB etc.) at the lowest voltage possible (stable).

Can't remember if I ran memtest after changing the timings

I know I have run orthos just fine
