Does the m17x r2 allow for custom memory timings?

I was looking at getting 8gb of kingston hyperx ram and in one of the reviews a guy said you need to be able to access custom memory timings in the bios and set it to XMP profile to take full advantage of the ram.

Newegg.com - Kingston HyperX 8GB (2 x 4GB) 204-Pin DDR3 SO-DIMM DDR3 1600 (PC3 12800) Laptop Memory Model KHX1600C9S3K2/8GX

 

The R2 is limited to 1333Mhz so whatever you do you'll not be able to take full advantage of those sticks in the R2 but i guess since they support 1600Mhz freq, they should have alot of OC headroom!
I'm waiting for my set to sit in the R1

 

Me too - I looked onthe Kingston website at various data sheets and if im right, (and Kingston too lol) the timings on this ram at 1333 should be 9-9-9-18.......a bit tighter than 9-9-9-24. They should handle OC better too like Katalin says.

I searched everywhere to try and find 4gb sticks at 1333 that had lower latencies but could not find them AT ALL.....all i could find was kingston hyperX 2x2gb at 7-7-7-20 i think from recollection (1333)

In my opinion these are probably the best ram sticks to pop in....at least im hoping so as mine should land in a week or so!

 

And as a final answer, yes you'll be able to put them and be able to use them in your laptop,they're just going to be downclocked to 1334Mhz(2x 667Mhz).

 

And as a final final thought, IF you get 'em, and IF you change to a Sandybridge R3 or "mythical M18x", you WILL be able to take full advantage of that 1600mhz if you keep hold of your ram sticks.....one of the reasons I got 'em......futureproofing!

 

I just installed the 8GB Hyperx 1600 Ram last week. The timings are the same which I was a little dissapointed. However as people have said before they have a lot of room for overclocking. So when you overclock the system with the factorcy bios OC and then I use SetFSB you can get the RAM from 667MHz up to right below 800MHz which should be close to the stock specs of the Ram modules. The best part to is you can do all of this without even having to increase the voltage to them.

 

Just that not all of the 2nd gen i-core CPUs support above 1333Mhz eighter(eg. i7 2630)
Take a look at the CPUs technical sheet first

@ timbo126 increase the voltage only if needed,usually more juice = more stability.

 

But on the Kingstone website it shows that the 8GB 1600 RAM only needs 1.5v. So if its underclocked in the M17x and then I'm just getting it close to its stock specs by overclocking my m17x I would assume it shouldnt need more voltage since, to run at stock speeds it only needs 1.5v. I'll get a BSOD on my cpu before I do on the RAM without touching the voltage.

 

That's why i said ONLY(even in bold letters ) and that's a general rule.

 

Does this 1333mhz limit on the r2's include the 920's and 940 cpus, I was wondering since these cpus can suppose 1600?

 

Yeah - I did spot that but if i were looking for a new SB laptop NEXT time around, it would have an extreme cpu for sure.....thats why im futureproofing lol

Yeah, you wont get better than 1333 out of any R2 cpu afaik extreme or not....unless OC'd

 

Heres with 8GB hyper X 1600 first pic is non overclocked and second pic is overclocked with bios settings and SeftFSB

 

Wow - nice! .... 1500+mhz....now I AM looking forward to getting mine.....are you stable at those timings?

 

Yeah its stable I'm also running throttlestop with it as well and yeah it really shows some increases. I did a PCVantage benchmark test with a my R2 stock and scored a 9,987. Last week I added a SSD and re applied the the thermal paste so I could OC a little further as well as change out the stock ram with the Hyper X. I just ran another PCVantage test and scored a 15154. Most of that is probably the SSD but still big jump with the higher OC.

 

Nice.....I wont get those figures with my 840qm but may get an xm down the line.....

 

Sorry if this is a dumb question, but how do you overclock your ram? Is it done by increasing the rams voltage in the bios?

 

I would like to know this too! - especially any info on XMP stuff

 

Well our motherboards don't support the XMP feature so it doesn't have an effect for us. But to overclock the RAM fou just have to increase the FSB. This is what the overclocking feature in the BIOS does as well as SetFSB. So when the FSB is increased the CPU and RAM speed are both increased. Increasing the voltage does not have affect on the speed. Only increase the voltage if you have to, which you should not have to.

 

So, basically, use SetFSB utility (download) to overclock. I believe that unless you have an extreme cpu (920xm/940xm), you are unable to OC in BIOS - those features are grayed out/inaccessable. I think you can increase the voltage to the ram but like you said before in your earlier post, you shouldnt have to do this as its designed to run at 1600mhz at 1.5v, correct?

 

That is correct, 1.5V is enough juice but keep in mind that raising the FSB doesn't only stress the CPU/RAM but everything in your system!

 

Well the BIOS OC isn't that much. The max you can get out of it is 5%. You can actually get much more out of SetFSB. As long as you have the option to increase the voltage to the cpu to be able to support a higher OC, then you should be able to get somewhere with the FSB. Theres a guide to OC'ing with SetFSB on this forum and the guy who wrote it doesn't have a 940x, or a 920x.

 

Yeah, think I flicked through it some time back....from recall, my understanding of it was that SetFSB is the ONLY way to overclock an non extreme cpu.

Will have to locate the thread and have another read....

Cheers Timbo.

 

Check out throttle stop to it doesnt affect the FSB but it does show some nice performance gains and I think it does work on non extreme CPU's

 

Yeah, another thread ive looked at and heard people use to great effect. I am not too sure thought about how it works on non-extreme cpu's as the multipliers are locked in bios. I think Kevin (Unlclewebb) said that it doesnt work but I could be wrong.....another read of his thread is in order when my ram arrives.

 

Just download TS,Steve,if the options are grayed out then you can't use them if they are available then you can make use of them.

cheers

 

Yeah, if you never try something, you never know eh?

 

It doesn't hurt to try
Be sure to read thru the Throttlestop guide and to press the UNLK button,after that is up to you.
I can almost bet you'll be able to use it as my old Q9000 was not an extreme cpu and was able to OC it.
