RAM OC - possible on NP9377?

RAM speed does matter when CPU becomes a bottelneck, like in SLi systems. Is 1600Mhz all that can be used on NP9377 or can it be overclocked to 2133Mhz with looser timings?

 

Definetly.. 1866MHz works for sure but I'm not sure about 2133MHz.. It all depends on CPU+Memory controller but 1866MHz will be doable with a 4810MQ++...

 

1) make sure your ram sticks support the speed u want to clock them at. best bet is to go with sticks advertized as 2133. i myself have 2133 corsair vengeance sticks that can do 2200 stable and 2400 bootable (but unluckily not prime-stable )
2) loosening up ram timings helps when overclocking the ram frequency
3) another thing to consider is the CPU IMC (integrated memory controller). to make sure to take it out of the equation, theres the option to feed more voltsh to the cpu´s system agent and digital / analog IO segments in order to stabilize the IMC at higher RAM frequencies. that is, of course, only an option if your model supports that in intel XTU or system BIOS (Prema to the rescue?!)
4) thorough stress testing is a MUST with ram, since the whole system stability is depending on it! no ram = no system!

 

1866mhz is plenty even for an overclocked sli system

 

plenty? PLENTY?! blasphemy!

 

So does NP9377 have the ability to overclock 1600Mhz to 2133Mhz or whatever speed I select or not? I am going to use the 1600Mhz RAM that comes with XOTIC configurations, but I'll try to go for the CL9 RAM as its more than likely to OC higher than standard 16GB 1600Mhz RAM XOTIC offers. Does it have a BIOS where I can change RAM speed to a higher one and increase voltages, etc? I know all about desktop OC, timings, voltages, stress-testing, etc. I don't know if NP9377 has the same or similar options that allow to do the same.

 

With the prema bios you can do it in the bios. On a regular system you can do it through xtu.

 

Where do you get your info? In too many threads you write things that aren't true. Ram speed does not bottleneck SLI. Bandwidth matters not speed. You don't need 8gb of ram for AAA games. You just realized 17" laptops are 17" even though spent weeks asking questions about which to buy.

....

 

Bandwidth affects minimum framerate in systems where CPU is bottle-neck'ish or at least where both CPU and GPU are balanced. I personally tested my own desktop along with other credible review sites that tested slow RAM vs. fast RAM in systems with powerful SLi videocards and found that higher RAM speed does affect MINIMUM framerate. For example, even my desktop 3770K @ 4800Mhz with GTX 980 @ 1550/8000Mhz and 16GB of RAM produces similar average FPS in games when RAM is set to 2200Mhz vs. RAM being set to 1600Mhz, but benchmarks show that minimum FPS are up to 10-12fps higher when RAM is at 2200Mhz. I used identical timings for both 1600Mhz and 2200Mhz. Minimum FPS is quite important as stutters are most often experienced when framerate dips into much lower one (minimum FPS). Faster RAM prevents those dips on systems where CPU is either balanced with GPU or slightly bottle-neck'ish.

Anyway, I would rather ask 1000 questions and make 20 threads than end up with a laptop I do not like because I didn't realize something simple or complicated. I just hope its not bigger than my 23.5" LCD or else its not very portable. It's not my fault my sister dropped me for the LUL'z when I was only a tiny man with minuscule peepee. She was jealous, but I forgave her, although not the flattened upper left side of my skull that messes up with my brain's logic center.

 

Is it that hard to just have one thread with 20 questions, instead of 20 threads with 1 question each? It does get annoying to be honest.

 

One thread with 20 questions would result in just a few replies with a few SHORT answers per question (as it would overwhelm the participants), which is going to lack detail and details are everything. A single questions per thread opens up an entire topic theme, where replies are usually more frequent and contain more related information. I would do 1 thread with 20 questions if it worked, I tried that in the past SO many times, but it never worked, not once! Besides, an answer can open up a lot of questions. The smartest thing to do is to have one topic per one thread on SEVERAL forums because many replies may end up incorrect or worthless. You need a truly thorough research to be prepared for what is to come or to know what it is exactly you will end up with. Be glad - I am running out of questions to ask!

 

96% of the time google search will answer a lot of your questions or send you to places where someone asked the same question. . But thank god this forum is here for the other 4%.

 

Not sure if someone answered this, but if you get Kingston Hyper X Impact ram, it will scale to what your laptop can handle which is 1866 (I have same as you), though the ram itself can go to 2133Mhz or 2666Mhz I "think".

 

Is Kingston HyperX different than HyperX Impact?

 

HyperX Impact is Kingston HyperX SO-Dimm ram. So answer is no, no difference, it's the same thing.

Cheapest price I've seen is from TigerDirect for 2133 HyperX Impact.

BTW Corsair Vengeance 2133Mhz DDR3L RAM has slightly better stock timing ratings at 2133Mhz than the same speed Kingston HyperX, so if you can get both around the same cost, might be better going for the former (which is what I did):

Corsair Venegeance: CL 11-11-11
Kingston HyperX: CL 11-12-13

 

Impact is the branding they recently brought in for SODIMMs, they used to just be called hyper X.

I have some Hyper-X PC3-8500 CL5 ram lol.

 

Faster RAM makes little to no difference in games, except for a couple. Battlefield is one of them, although it's still minor. 1333 to 2133 MHz compared here: http://www.overclock.net/t/1438222/battlefield-4-ram-memory-benchmark
Results in 13% improvement, but that's 1333 vs 2133, and 1333MHz is quite slow to begin with, and it's not linear, meaning another 800MHz won't make it another 13% faster.

See here: http://www.bit-tech.net/hardware/graphics/2013/11/27/battlefield-4-performance-analysis/9

Difference here is a mere couple FPS at best from 1333MHz to 2333MHz.

My 9377 came with HyperX 1600 sticks. I pulled them and put in the Kingston 1866 sticks that came with my Alienware 18 R2. I had to click on the XMP profile in Intel XTU to get them to run at 1866. They ran at 1333 by default.

After getting them to run at 1866, I clicked on the custom settings option and bumped up the memory multiplier from 14x to 16x in XTU. I even got bold and copied the timings from the 1866 XMP and entered them manually for my attempt at 2133. It worked. I ran Memtest86+ from dos for an hour to check for errors. There were none.

While I may have gotten lucky with the way I did things, the answer though is yes. The 9377 will run memory at 2133.

 

Yes so long as the sticks are capable of it and the memory controller is not a weak one then you can.

 

Very true. I've always had the best luck with either overclocking the memory or running faster ram out of the box with a XM chip. Not sure if that is coincidence or not.
