[HowTo] SO-DIMMs Extreme: Boost 1600 to 2133 and beyond / JEDEC & XMP

And I'd like to see some gaming benchmarks done as well, to see if there is an actual performance improvement going from 1333 to 1866 with the HD 3000 integrated GPU.

 

I can see that the majority are very skeptical and am not here to argue or prove anything. Just my 2 cents: went from 1333 to 1866 and immediately noticed a "snappier" effect. The entire system felt...more responsive.

Take it or leave it.

 

I just ordered 16gb of the 1600 version of this. It was £75 for the 1600 or £150 for the 1866. Did not think the extra speed was worth twice the price.

 

I also have some good information regarding memory for the Asus U24E-XH71:

I changed over to the Corsair Vengeance (from G.SKILL 1333 9-9-9-24 1.5v) and sure enough out of the box the RAM was clocked at 800MHz (1600), even with my i7-2620M. I didn't think it would work because according to the Intel's ARK page, this CPU only supports up to 1333 memory.

I ran into this over at Newegg:

Newegg.com - G.SKILL 8GB (2 x 4GB) 204-Pin DDR3 SO-DIMM DDR3 1600 (PC3 12800) Laptop Memory Model F3-12800CL9D-8GBSQ

Works Great - Lenovo T420 Sandy Bridge
Pros: Works out of the box. Runs at DDR 1600 on the Lenovo T420 i7. Yes, it does run at DDR 1600 on the i7-2640M, despite what the intel webpage says about that processor.

Core i7-2640M Sandy Bridge. CPU-Z reports all JEDEC Values as advertised. 800MHz 9-9-9-27-39.

There's a JDEC for 977MHz at 11-11-11-33-48 for anyone that adventurous.

Type: DDR3 - Channels # Dual - Size 8192 MBytes - DRAM Frequency 797.6MHz - etc, etc, etc.

Cons: Didn't come with nano-bots to install itself for me.

Other Thoughts: Confirmed speed with MaxxMEM2"


I then went ahead and bought Thaiphoon Burner Super Blaster - Professional Edition (7.4.0.3 Build 0212), downloaded it and managed to write the missing XMP profiles onto the Corsair Vengeance timings chart. I successfully added an Enthusiast (DDR3-1866) and Extreme (DDR3-2133) profile. But for some reason only the 1866 profile can be utilized. This could be due to my CPU, my motherboard, or maybe my BIOS. Im not sure.

Using several applications like MemTest+ 4.20 and HWiNFO64 I was able to confirm that the timings and overall clocks did change. I am now successfully using "1866 ram". I will post some benchmarks and my general findings a little later.

All I can say is that in some preliminary benchmarks, the performance increase was definitely there. To me, the system seems just as fast as before. Applications and my desktop load very quickly, and switching between apps is smooth.



See here for my thread on upgrading choices to 1600 ram:
http://forum.notebookreview.com/har...es/645340-ram-timing-voltage-cas-latency.html

 

wow well done buddy !!! I can see in your sig that your ram is now 1.65v ? Shouldnt it be 1.5v?

 

I think you might be right. I saw 1.65V so I thought that was the profile I was using. But i think I'm at 1.5V 1800, non xmp.

Check this out:

 

Someone has timings for/ experience with corsair vengeance CMSX16GX3M2A1600C10?

 

Hey! I want to tell you that I will get Corsair 1600 2x4GB soon! Yahooo!!!!! You also can buy it for only 44$ now on Newegg! Newegg.com - CORSAIR Vengeance 8GB (2 x 4GB) 204-Pin DDR3 SO-DIMM DDR3 1600 (PC3 12800) Laptop Memory Model CMSX8GX3M2A1600C9

Also I remind that it is possible to OC it to 1866Mhz.

 

Here is screen of the Corsair 1600 C9 running at 1333Mhz on L702x
The timings are 9-8-8-20 [email protected] - I wonder will it do Cas8 or Cas7 on the 1333 with the Thaiphoon Burner

 

I am going to use it on CL-7 timings on 1333Mhz when I get it. As it shown here http://img109.imageshack.us/img109/8809/p1190034.jpg
However, are you sure that your RAM works so slow with 2-nd Gen I-core cpu??? Use winsat mem command on command prompt and Everest tests.

 

Yes, i'm sure as the 1600 is at 9-9-9-24 and the image you're showing is about 1866 which at 1600 is at 8-8-8-20 (big difference) and as we all know the L702x is locked at 1333 so i was only wondering at Cas8 would it go. Though and this 9-8-8-20 is good.

 

Ok if you all know it And yeah, when you add suport of CL-8 using Taiphoon you will have 8-8-8-20 timings.

However I shew you that photo because it is possible to write 1866 mhz ram's profile to 1600 mhz one. Which has been already done. I didn't tell this here before because that ram was used only on 1066 mhz because of another laptop's limit and never tested on any higher frequency

 

I'm not saying that i know all but thats a bit interesting - does this mean that 1866 and 1600 are the same ?!? Just with different ROM ?

 

Memory chips are different. At least they are marked different. But every quality RAM has potential to be OCed. Some RAM is pushed to the limits by manufacturer and this is why some stick are working and some were DOA or had compatibility issues. Like HyperX was at the beginning. It is possible to OC 1600 to 1866. But you will do it at your own rrisk. I would take that stickers away just in case and surely put RAM in well cooled laptop. not netbook.

 

Thanks for the info - in that case i would try for now to enable the Cas 7 and 8.

 

I have just added link on improved and slightly OCed Vengeance 1600Mhz RAM in the first post. It was OCed to have CL7 timing on 1333 Mhz system. And added 1866 XMP profile. This profile HAS NEVER BEEN TESTED BEFORE! I'm not responsible for anything.
While stock adding CL timings will let RAM work on 8-8-8 timings on 1333.

Do you know if someone has ever tried to flash their HyperX 1600 (PnP or not) to 1866 mhz with Thaiphoon ?

 

I'd like to know this too... would be sick if we could flash 1600 to 1866.

 

Sorry, I don't know about hyperx. I believe it is possible to flash but nt sure if memory chips can handle that kind of job. I may try this but only on Corsair. in 3 weeks.

 

Just flashed my Kingston HyperX 1600Mhz PnP 2x4GB with the Improved Corsair Vengeance 1866 THP Profile and in my unlocked bios I set XMP Profile 2, 1867 and 1.65v.

I booted up fine and I am now seeing this;



???

 

WOW ! 1st of all well done ! I can now see you got your GTX580M !!! Might try to flash my HyperX also

 

Ok, restarted, set bios to auto and some benchmarks:

 

Let me try now

 

Here's my U24E, same CVs. Same profiles.

Checking out my BIOS, Memory Clock Frequency is selected to AUTO

Can anyone upload the stock Kingston HyperX 1866Mhz PnP thp profile, please?

Purely for test purposes!

 

You know this profile (hyperx 1866) is worse than yours (corsair 1866) Why do you wanna try ?

 

Just interested!

Cause the XMP Profiles in the improved Corsair profile are not actually as good as what the RAM runs at default (on improved profile)...?

 

You can manually cahnge XMP profiles by yourself. Like lowering power and decrease some timings.

 

Writing to the RAM can only be done on a licensed copy or... cracked copy.

Either way, you can tweak your settings and at first it does seem scary. I haven't done any custom tweaks and have yet to bother to learn.

 

Did you ever find the 1866 xmp profiles for kingston?



edit:
I just did these myself..



And here it is running 10-10-10-32@1920 mhz from factory 1600 mhz.
Going to have to say kingston ram is pretty good, but i'm still testing....

 

Did you remember to back up your ram?

 

Who?? me??

Side note:
Just so you guys know...1866 ram can run higher than 2200 mhz. Here is 1600 mhz ram running at 2200 mhz...

Spoiler

 

WOW...someone is having fun.

Rep +1

BTW, does 1,65v help for tighter timings or only higher clocks? What's your observation?

 

Yeah, I am. lol

And yes, the 1.65V does in fact help when you have more memory or really tight timings.

 

No I didn't find them!

Please share! Or even better, your custom profile with the 2000Mhz XMP

 

It's not running off of xmp profile.
And you can make the change easy enough. As long as your board supports 2133 and higher speeds.

Heck, i have my dell factory ram running at 2200 mhz...haha
I wish i would have remembered i could do that. After all the time Scook9 and I spent on this way back when.


Edit:
Maybe it is running off of xmp. Going to have to check that out again...

 

johnksss,

If you could provide your custom .thp, it will be greatly appreciated

Also still looking for the 1866 HyperX PnP .thp if someone feels helpful !

 

What does your system support?

And are those 4 gig or 2 gig chips?

 

Here you go, 4GB HyperX 1866mhz PnP, clean dump:


Kingston 9905428-048.A00LF.thp

 

Thanks prema

Edit:
Wow, no xmp profile in it. really?

 

Good that it is changeable

 

Yeah it is...Going to test it out now. Going to drop that 11 to 10 as well

 

What do you mean by I can make a better with my own profile ? If I want to increase the clocks (1600>1866) I do need to know all the timings changes, don't I?

I got 2 x 4gigs btw and will try out the Prema .thp Thanks Pre

 

Hummm, with the one prema just posted you would be fine. Just flash and go. The cl11 isn't making a big difference from my testing, but it also doesn't seem to want to run at cl10 either. could be because i have other ram in there as well.

 

Much appreciated! Flashed flawlessly.

Hope they are more stable (for me) than the Corsair 1866.

 

It should be. These 4 gig chips seem to hate cl10. grrrrrr

 

Yep, I would get occassional "This program has stopped working" errors on the Corsair 1866 @ CL10 (even though it passed memtest). I think my laptop shutdown once. None of these problems on the HyperX 1866 @ CL11.

I am flashing/overclocking my PnP HyperX 1600.

Upload your thp or xmp profile for the most stable 2133!

 

Could you tell me what ram are you ocing? Of vourse cl11 timing is much more stable.

 

Its Kingston HyperX 1600 XMP 4GB if I'm not mistaken.

Yeah mine with the Corsairs flash doesnt seem to be very stable. I do get occasional shut downs. Not often, but just enough to get annoyed.

 

Err guys I said I was flashing my HyperX 1600Mhz PnP RAM

I am very happy with the stock HyperX 1866 now. Not a single issue yet. It's fast, stable and reliable. Usually you can see instability after a few gaming sessions and internet browsing (like I did before), none of the sort now.

Anyways, hope I haven't jynxed anything. Hope my petty 1600Mhz can deliver at 1866 lol So far so good, stable all day.
