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

I paid for TPB and my license is for a year only. I've talked to one of their reps and this is what I've been told.

Thanks a lot! This profile is stable so far. I used my 6475b today with Minecraft, ran some benchmarks and stability tests in AMD's OverDrive application and it seemed ok. I'll run memtest, prime, AIDA stress test and a bunch of other tests later todays (if time permits). Both RAM sticks worked fine in Windows 7 and 8. I like how you added 1866 JEDEC into it and the 1600 CL timings were smaller/tighter/shorter/etc. I want try and tweak the 1600 timings further.

However, my 6475b will not run them at 1866. It's not the RAM, its got to be my 6475b. The next thing I'd like to do is try and have an expert unlock and customize my BIOS/UEFI. Maybe then I'd be able to hit that speed. If after that its still not possible than I can safely say its the APU and or motherboard chipset causing this. Its likely AMD just didn't allow this to begin with.

I do not suggest lower timings to CL8 for 1600. I can still quicker the responce setting somewhat faster CL9 timings. It will take same 9 tacts but faster one. However if I lower latency for 1600 I do the same for 1866. Which means if you put RAM to 1866 laptop it may not boot or heat or be not stable. So you decide what you want: 1866 RAM or somewhat responsive RAM which you hardly notice.

Did you see any laptop with such APU with 1866 fully utilised?

 

How come no matter what setting I put on in the bios, the memory frequency stays at 1333mhz on my Clevo W110er?

I'm using Prema Bios 1.4 and the Corsair Vengeance 2x8gb 1866mhz kit.

Any custom latency setting I set stays and works (currently running 1333mhz CL6 linx/3dmark/max payne 3 -stable), but the frequency won't.

I set the mem profile on XMP #1 instead of custom, and I hat to take the bios battery out to get the laptop to start up again; it'd just shut itself off instantly.

 

could it be that ur cpu's IMC just doesnt support such high frequencies and thus resets any input at boot? have u tried 1600 yet?

I have, nothing higher than 1333mhz works. I'm happy with the sticks taking it down to CL6 even, but I'd still rather have them go to the rated 1866, or even higher at looser timings.

I'll see what the i5 brings to the table, I won't be bottlenecked by ram, but I'll sure as hell max them out once I learn how.

 

have u maybe tried those higher frequencies at ur super tight cl6 timings? if so, just set those timings really loosely, to like cl12. then try 1600 and see if it sticks.

I forgot to mention I tried every setting from 800 to 2133 and latencies from 5 to 13.

Only 1066/1333 modes work, on CL5/6 minimum.

 

can someone help me! i cant get my samsung memory to post anything other then stock no matter what i change in Thaiphoon burner

 

nrat, when did it happened? since the beginning? What exact samsung RAM?

 

well i just got the program today ive been overclocking with intels xtu

im using samsungs 30nm 4gb sodimms

 

Edit SPD and add some XMP profile.

then power drain your laptop.

Boot and read profile. And compare.

 

ok ill try that

any ideas on some really fast profiles for it?

on xtu i had it at 2000mhz cas 9-9-9-24

 

I have a problem to write my Micron Rams with TPB. (On my Corsair Rams TPB worked fine)

When i try to write SPD on the Microns, the SPD does not change, it is allways the factory one, but in TPB is seems the Rams arent write protected, and i can change the Part Nr. and i can endable and write XMP profiles, but standard SPD write does not work. Why???

 

Are all the new RAMs write protected or why so difficult to find an unlocked DDR3? Anyone has experience with these Micron RAMs? These are not PSW protected, base clock 1600MHz Cl11 near 1.35V. Could these run 1866MHz CL9 near 1.5V?

 

Hey James D, thanks again for your time. I was aiming at running my 4gb Samsungs @ Meakers timings, but I'm still trying to figure out how to adjust values. I appreciate your help.

Hi anyone upload best performance pro file forma corsair sodimm vengeance 1866? I ha ve tried but not lucky

Atom Ant,
Micron, Nanya, Elixir, Samsung and Hynix write-protect the first 128 bytes of the SPD EEPROM device. The best choice is Kingston so far.

 

I plan on getting this for a future Kaveri laptop: Amazon.com: Kingston HyperX Plug n Play 8GB Kit 2133MHz DDR3 PC3-1700 Non-ECC CL12 SODIMM Notebook Memory KHX21S12P1K2/8: Computers & Accessories

Can the Kingston HyperX PnP 2133 mhz CL12 be edited? Or is there a better RAM to edit?

 

I think this what you have to look for;



If the modules ain't write protected, than you can edit timings, speed, etc. I'm currently purchasing different type of 4GB modules and will test them with AMD laptop to see how far can I go. An A10-5750M would be big help to test 1866MHz speed.

 

I'm interested to see how much performance gain would CL9 have over CL10 at 1866 mhz.

 

Minimal on Intel systems. The aggressive caching on the Sandy Bridge+Ivy Bridge architecture hides the latency so well it doesn't really care if the system RAM can turn stuff around faster. What it does care about is the odd occasion it does need more data than the cache can hold, the speed that the RAM can deliver the data (i.e. bandwidth) would then provide the biggest influence (however, even this tops out at about 2400mhz with vast diminishing returns beyond)

However, I do know AMD systems love latency improvements (at least for the Phenom II series) so we may see a benefit.

 

I've purchased the program too and have exactly the same problem as you. So far I tried with two different types of Micron and a Samsung module. Adding XMP profile won't help anything on me, I want edit Jedec timing table! My modules are not PSW protected, so why does not this program working?

 

Atom Ant, all SO-DIMM modules manufactured by Micron Technology and Samsung are protected with reversible software write-protection that does not enable the first 128 bytes of the EEPROM device to be programmed. If Thaiphoon Burner is not capable of programming the first half of SPD array, but it can the second one (80h-FFh) then your module is 100% write-protected.

 

That is just great, than what is this program for if all the modules are write protected? I've two Kingston modules are coming too, will see if that makes it worthwhile.

 

Atom Ant, ask Kingston or Micron why they protect SPD EEPROMs before you ask me about the purpose of Thaiphoon Burner. For your knowledge, reversible write protection is a requirement of JEDEC DDR3 SDRAM Standard. However, most of DRAM module manufacturers still do not comply that requirement.

 

Obviously they do not wanna users to make high specs RAMs from cheap modules, cover with warranty. The another problem is factory high specs RAMs are just not exist, like 1600MHz CL8 or 1866MHz CL9, so double no way for users...

 

Kingston used to sell 1866 mhz CL9 sodimm sticks... The only issue was that they were limited to 2 GB per stick, and are somewhat hard to come by.

 

I can vouch for the kingston hyperx pnp series being totally unlocked. However they use crap hynix ics which dont oc as well as the samsung ones. Strangely of my matched pair of oem samsung lovo sticks, one is unlocked while the other isnt.

 

Yes, Kingston memory modules can work with Thaiphoon. I managed down a pair of regular 1600MHz CL11 Ram to CL9 and a pair of Hyperex 1600MHz CL9 to CL8;



Aida memory reading speed went up by 170MB/sec, which great for Trinity APU. Next time I gonna mod to 1866MHz.

 

I bought the expensive 1866mhz one and managed to get it stable at 2133mhz with the 12-12-12-2t JEDEC binning. HD4000 performance is amazing, DOTA2 no longer lags. Shame my Samsung sticks are locked as they could've easily done 2400mhz 14-14-14-2T

 

Not bad, what Hynix chips use yours? I've checked on Newegg the 2133MHz version,which use the same h5tq2g83cfr chips as my 1600MHz modules. Probably I can also turn my 1600MHz modules to 2133MHz monster
Any other tweakable Memory, maybe the Corsair 1866MHz CL10? Now I want 1600MHz CL7...
+Rep for you, convincing purchase Hyperex RAM!

 

Yesterday, I received from Corsair Memory the latest SPD dumps for 4GB and 8GB DRAM modules. The SPD dumps contain the newest XMP 1.3 profiles: XMP-2133, XMP-2400, XMP-2667, XMP-2800, XMP-2933! I have added all 28 SPD dumps to the common database of Thaiphoon Burner. The list of SPD dumps is attached.

 

New 4 and 8GB modules coming from Corsair? Otherwise those high speeds doesn't makes me sense, James D wrote somewhere Micron d9pfj chip cannot really reach 2133MHz.
Anyway XMP ain't useful for me, Do you know if I can edit the Jedec timing on Corsair Vengeance 8GB 1866MHz CL10 RAM, just as I did with Kingston? Micron d9pfj might not good for 2133MHz speed, but maybe can take tighter timings at 1600 and 1866MHz speed than Hynix h5tq2g83cfr.

 

Atom Ant, Corsair does not write protect SPD EEPROM. So, it is possible to reprogram all 256 bytes of SPD.

 

Mine are Hynix h5tq2g83cfr PBC 230V with the secondary binning serial: dwldl380h2.
I'll PM you my set of OEM Kingston memory pnp profiles. Only flash 1 chip at a time I can't guarantee it will work with your cards. I found the limit of stability without resorting to XMP on 2T with my sticks was either 1600mhz 8-8-8, 1866mhz 10-10-10 or 2133 12-12-12.

Heres the OEM profiles

Many thanks, the 1866MHz profile seems to working well! Now I have to just find the lowest possible timings for this new frequency.

 

Have you checked through benchmarking that the APU is accepting the 1866 mhz? Last year someone tried it by using 1866 mhz RAM sticks, only to notice that the system was constantly hovering around 1600 mhz, and rarely peaking at 1700 mhz.

 

Guys, I need some help... I'm using Asus U36SD with Core i3 processor and have bought Samsung Low Voltage DDR3 SODIMM 4GBx2 PC12800, according to CPU-Z my RAM is running at PC10600 (1333) not PC12800 (1600). Any chance I can run this kit with PC12800 speed? Or is there any limitation on my hardware maybe the Core i3 or Intel HM65 Chipset. Thanks a lot guys

 

hm...not sure but it could be that the core i3´s memory controller only supports up to 1333 speeds.

 

I'm 95% sure its to do with the i3 memory controller (according to the Intel Spec sheet) as the Samsung RAM has the clock profiles on JEDEC so it's unlikely to be XMP implementation. That being said, I have seen Desktop motherboards with specific chipsets that are unable to accept RAM faster than 1333mhz despite having i5s or i7s.

I've changed my A4 Trinity to A10 Richland and 1866MHz speed is no problem. Currently I've lowered timings to CL10-10-11-32 and it is not the end. Unfortunately I've very little time to play with it, hopefully on weekend I'll find the lowest timings...

 

Hi,

Can anybody help me?
I have 2x8Gb Kingston LoVo memory.
Micron chip: D9QBJ
I can't write a new spd into my memory with Thaiphoon Burner.
Video:
Original spd dump:

What can I do?
Thanks.


#07. WHEN I TRY TO PROGRAM NEW SPD SETTINGS IT GOES BACK TO THE ORIGINAL SETTINGS.
Samsung, Hynix, Nanya and Micron are used to protect SPD EEPROM of DRAM modules. The first 128 bytes of SPD may be protected from being written because of enabled RSWP (Reversible Software Write Protection), PSPW (Permanent Software Write Protection) or hardware SPD EEPROM protection. The second half of SPD bytes usually remains unprotected enabling the user to program Intel XMP profiles.

 

Did you pay for the software?

 

Yes, of course.

 

visp, usually the second half of SPD registers remains unprotected to let OEM suppliers to store specific information, e.g. XMP profiles. To check whether bytes 80h-FFh are not protected try changing any of these SPD registers manually. For example, read SPD EEPROM first, using HEX Editor change register F0h from 00h to AAh by typing 'AA' from the keyboard. Now read SPD EEPROM once again and verify whether register F0 has a value of AAh. If so, the second half of registers is not protected and you can program XMP profiles.

 

Hi,
Unfortunately, read-only.: (
Thanks.

 

visp, I am very sorry, but the SPD EEPROM chip is totally protected using hardware write protection. This is something new to Kingston modules! I have never seen such a "trick" from Kingston before.

Here is some portion of information from Atmel AT34C02C datasheet: "The write protect input, when connected to GND, allows normal write operations. When WP is connected directly to Vcc, all write operations to the memory are inhibited. If the pin is left floating, the WP pin will be
internally pulled down to GND. However, due to capacitive coupling that may appear during customer applications, Atmel recommends always connecting the WP pins to a known state. When using a pull-up resistor, Atmel recommends using 10kO or less."

 

No problem.
I can get the memory back to the store within 3 days.
Thank you for everything.

 

So far, the only modules that are not write protected that I have encountered is the Kingston HyperX PnP or some of the obscure OEM sticks with Hynix/Elpida modules.

 

I can not believe it.
The Crucial memory is also write protect.
Original SPD dump.
Picture:

Excuse me, one thing I don't understand.
If I read SPD EEPROM and change any value in hex editor.
Nothing will change if I read SPD EEPROM once again.
Since I was not save change before.
Is not that right?
