Problem with my Corsair RAM

[PcWindowsGeek1]

Hi,

 

When i set my ram to 1600mhz my computer crashes but when i set my to 1333mhz is nice and stable. Need help sorting this problem out.

 

PC Specs:

 

Asus P8Z77-V PRO

Intel 3570k overclocked to 4.3GHZ

Corsair CML8GX3M2A1600C9 LP Vengeance 8GB

Sapphire 7950 Vapor x 3GB

Corsair HX 750 watts

Are you setting the voltage and timing correctly on the RAM?

[fishymamba]

Instead of manually changing the RAM speed, turn on XMP. That should automatically set it to 1600Mhz with the recommended settings.

If you did the above then it may be that that particular RAM sticks are not compatible via the XMP profile. Check your motherboard's memory-QVL to make sure it is listed as compatible.

Yes I've checked my voltage and timings and they were set correctly but still crashes at 1600mhz, I've even tried the XMP profile still crashes at 1600mhz.

My default Ram voltage is 1.5v and timings are 9,9,9,24 2t

So is there any solution for this problem?

Set your voltage manually to 1.5V, that's a safe spot for many modules. Also set your timings manually to something like 11-11-11-28-1T, and lower them from there once you know that they're stable at 1600MHz.

it didnt work, what now?

Do run memtest86 though, even if the sticks are new! A little memtest never hurt anyone

Try 2T and 1.55V, and did you set all of that manually? Do you have any other RAM-related settings that are not manually configured?

ive did a memtest and it failed at 1600mhz

everything is manually set

It's still not working? You may have some poor DIMMs for overclocking. It's not a big deal though since there is almost no real world performance gain from 1333MHz to 1600MHz in most scenarios.

so the problem is the ram not the motherboard?

[Art Vandelay]

You could try increasing the DRAM voltage to 1.65V or the CPU VTT voltage. One of those might be the problem.

It is most likely the RAM that isn't meant to be overclocked that high, although it could be the IMC (integrated memory controller, inside the CPU). I wouldn't consider it to be defective, since the RAM runs at its stock speeds, but to get a higher overclock on your RAM your best bet is to find more overclockable modules.

That's a very high voltage, it's very risky.

[Hyydrah]

What a coincidence, I just recently overclocked my RAM to 2400MHz, they're very inexpensive modules that cost me around $50 CAD. They're known to be one of the best overclockers as far as frequencies go, they can be purchased here.

Let me know if you need any help with setting them at 2.4GHz.

Not at all; 1.65V is a standard voltage for RAM. Sandy Bridge had a fairly weak IMC in terms of voltage degradation, and it was easily able to handle 1.65V for prolonged use. There's no doubt that Ivy Bridge should be able to handle 1.65V.

The DIMMs have a lot to do with voltage tolerance, but 1.65V is really pushing it. Sure, it might work, but it isn't worth the risk for the virtually unnoticeable difference.
