RAM Overclocking

[pbenologa]

Currently my ram kit is 

Gskill Ripjaws X 8GB 4gbx2 DDR3 1600 CL7 (F3-12800CL7D-8GBXM)

 

Can i overclock it to 1866 CL(*). And how do i do that? My mobo is a MSI Z87 G45. Thanks!

Read this.

 

To be honest, you won't notice any real difference whether it runs at 1866 or 1600.

[pbenologa]

You will have to increase the voltage and CAS latency to maybe 11 to get it to post at 1866.

 

In my honest opinion the negatives outweight the benefits and I wouldn't do it.

I do remember experiencing blue screens whenever i turn on XMP. Because when XMP is disabled the speed is only 1333mhz.

You shouldn't bluescreen with XMP on, XMP is the manufacturer's profile to automatically enable the default rated settings for the RAM and should always work.

I dunno. Bluescreens was having a party when XMP is on. So i set the RAM speed in my mobo without using XMP. I'll take a look again later this evening.

Have you also changed other settings for example a CPU overclock?

Have a look later and see if it's something obvious.

Nope. I just changed the XMP setting. Nothing more.

OK, maybe someone who knows more than I do about RAM will come in and answer.

Change the frequency, change your timings, and adjust voltages until you it posts.

 

CL7 at 1600mhz is already excellent. It's it's a great kit, 1866 at CL7 would be great, but if you have to sacrifice to CL8 for more mhz it's not worth a dime.

 

Pump that voltage. stay under 1.6v. memory controller built into chip.

Overclocking of RAM will give you 0 results. It's just waste of time. People do it only for benchmarks.

Yep i know. But i was experiencing some blue screens. That's why i thought maybe i should overclock/downclock it a bit. Whenever XMP is enabled, blue screen happens.

So if you enable XMP which has 1600mhz you have blue screens? How they work now? With manually set or downclocked to 1333mhz?

If XMP is disabled, RAM Speed is 1333mhz. But when I enabled it, speed goes up to 1600mhz, but I experience blue screens. I dunno how XMP works. As far as I know you just have to enabled it to support speeds higher that 1333mhz.

XMP is just a profile where there's written specs of your RAM. For ex. If I don't enable XMP my RAM automatically runs on 1600mhz with my cpu, but if I enable XMP it goes to 2400mhz, cause profile of my RAM is set to 2400mhz. You can manually set those settings in bios. XMP is just an easy way, where you don't need to manually set options for your RAM. Try manually set those specs for your RAM. If you have exact this ram go in bios & change it to 1600mhz, set these timings: 7-8-8-24-2N & voltage this: 1.50v. Save & exit. See if you still encounter blue screens. If yes, then certainly something in your PC (probably CPU) doesn't like these RAMs & you can underclock them to 1333mhz or buy new RAM if RAM frequency matters for you.

Ok thanks! That is exactly my RAM Kit.

No problem. Update this thread how your PC will perform after my suggestion

If you get something out of it, it has a benefit, therefore it's not a waste of time.  Some people enjoy learning new things and experimenting with their hardware.

 

Who are you to judge them by telling them it's a waste of time? This is a forum for enthusiasts, hardware lovers and tech lovers alike, why would you tell someone that making their "tech" run faster was a waste of time even if the benefit is negligible?

Calm down lol. Of course it it has benefit it's not waste of time. But in general use, mostly in gaming overclocking RAM gives a zero performance. If you do it because of that, it's waste of time.

And I don't judge anyone here.

So i tried it again, XMP enabled. My kit runs at 1600mhz CL7. And i get blue screens when playing games. So i disabled XMP set the ram speed to 1600mhz manually and i get no error. I guess CL7 is not supported or not compatible with my mobo. Now, the problem is i can't tweak the clocks to set it to atleast CL9. Currently it's default value is CL11. Or can i just ramp up the ram speed up to 2133mhz and leave it at CL11?

Wait, I don't understand. Can you manually set these timings in your bios? 7-8-8-24-2N

What timings are now when you set RAM to 1600mhz manually?

I can set the RAM Speed manually, but the timings i can't seem to do it. 1600mhz 11-11-11-24

Okay, 11-11-11-24 seems ok though. My ex red Ripjaws had also these timings on 1600mhz. Leave it like it is now. You should be okay. Far better than 1333mhz

Shouldnt I go for atleast higher RAM speeds when timings are lower?

[nokturrduk84]

I don't know. If you want try, but personally me, I would leave it a 1600mhz as those RAMs are supposed to run on that frequency.

Or maybe I can try lowering the CL down to CL9 atleast? I can't seem to find any guid on how to set clock latency in a Z87 G45 mobo.
