Alienware 17 and RAM overclocking

Asking here because I have no idea really...

You guys think the Ranger can handle pumping 1.5v on the RAM? I am hoping I can edit XMP to try running 2133Mhz RAM @2400Mhz or @2666Mhz

Have you guys seen this thread?

RAM overclocking may be the last unexplored region of overclocking on the Ranger. It will become more helpful as time goes and applications properly saturate available cores. The Division is a good example of this.

Your laptop supports 1.5v naturally. Your ram should be able to run at 1.5v if it is ddr3l or already runs at 1.5v if it is ddr3. The benefit of this is unlikely. Your cpu my underperform as well as you may introduce a slew of instability issues for no gain.

 

I've run four 1.35V memory at 1.5V and two sticks died. One after a few months, the other after about a year. Memory related errors increased over a few weeks one stick at a time until they were unbootable. They were both G.Skill 8GB sticks. I have run two Corsair 8GB 1.35V sticks in another system and they have been fine at the higher voltage. I even ran one at 1.6V briefly and it was fine.

The only good memory chips that made it to notebooks were in regular 4GB 1.5V Samsung sticks. For all the high end desktop memory manufacturers they would put all their good chips in the desktop sticks leaving junk for laptop sticks.

On pre haswell systems good samsung m471b5273dh0 sticks can do 2133 9-10-10 at 1.5V. Haswell systems can typically clock memory faster, so you should be able to do 2400 at 10-11-11 with good sticks. This will be better memory timings than you can do with any other memory, and low latency is supreme when at 1866+ MHz

The bad part about going the samsung route is the 4GB chips are programming locked, so the system needs to support bios or XTU memory overclocking. Additionally, the sticks are sold at 1600 11-11-11, and there are some dud sticks that don't overclock well since no binning was done.

 

I have seen the benefits of higher speed ram on desktops, so I assumed this would be the case for laptops as well. Overclocking anything can introduce instability its par for the course.

I wont know for a while yet, but have wanted to get a better understanding in theory until I do. Thanks for sharing your experience.

You may have noticed that a lot of the Ranger users here use 2133Mhz RAM as that was the highest speed available for DDR3. I am hoping that it will be able to stretch a bit further.

G Skill also has a kit, but they seem to be escaping my queries at the moment...

 

The return on investment on RAM speed is so insignificant. I always opt for size over speed, unless it’s priced relatively modestly. 2133 DDR3 SODIMM is beyond outrageously priced now.

 

Ram overclocking increases instability at a less discernable pace due to the way clock timings interact with the cpu. Ive noticed no real life benefits from going to 1600mhz to 2133mhz. The timings are slower so there is very little benefit if any. If you are chasing benchmarks its different but ram to me has always been the least beneficial overclock but regardless I'm happy to see anyone try anything with this old laptop. I want a better cpu so she can keep going a while longer.

 

I agree, but I will take anything the Ranger can give me.

The link will have some good data to pull from. Its not nothing, but I am not proclaiming double digit gains either. It helps in higher CPU overhead scenarios specifically.

Before I go to Korea I plan to rebuild the Ranger, will be dedicating a couple of weeks to modding and ironing out the overclocks, memory included provided I still have the time.

 

Bang for buck, a 4930MX, 120hz panel, and msi 1070 will give you the most out of the A17. Kinda sad 32gb of ddr3-2100 will run you as much as the 4930mx

 

I already have all that save for the RAM and 1070.

Though I plan to sell the 120hz panel and get the N173HHE-G32 panel instead. The glossy panel is just a serious pain to be streak free.

 

After a looong break, I'm posting, too much work these days..

High speed RAM and more populated banks loads IMC, With Haswell I think you might see more heat. I remember Mr. Fox used to run them OCed plus even in M18x R2 or AW18 you needed Thaipoon burner to run at 2133Mhz and loott of patience.

But as in how RAM effects the games and etc. You might want to take a look at this video at 4:41 mark.



which pushed me to get the upgraded RAM even though that's a 7700K 1511LGA CPU vs an old rPGA Mobile chipset, But I felt even a little benefit is useful to me. To add, the RAM in my sig with CAS 11 isn't available anymore to my luck it was PnP. Also DDR3L high performance RAM kits are going out of stock as expected, as of now only 1866 kit C11 is there from GSkill for DDR3L.

 

Well luckily the HyperX 2133Mhz modules can still be sourced, will probably be the first thing I grab just so I have it before it becomes more labor intensive to source.
