M17x R3 Stock RAM - SPD mod to XMP 1600MHz

I can confirm that I have successfully got the stock Hynix RAM shipped with the M17x R3 to run at 1600MHz, by flashing it with the SPD from a HyperX 1600 XMP module.

I have been stress testing this for a few hours with all 16GB loaded across the 4 dimm slots.

If you have the same RAM as me, then there is a good chance that yours will do it too.

To check if you have Hynix RAM, take off the back cover of the laptop. If you have Hynix chips with the code H5TQ2GB3BFR-H9C printed on them, you are in luck.

Here is the results.

i dont know where the ram is located in the R3,
but have you noticed any extra heat in the area close to the ram modules?

 

I've 3 slots of DDR3 1333 Hynix ram in my R3. Does that mean that I can run my RAM @ 1600MHz by tuning a few settings in the RAM?

 

I have the other stuff- Samsung, right? Would it be worth trying it with the other brand?

 

Yeah sure, the RAM will only run at 1333MHz until you enable XMP profiles in the BIOS.

I have stuck the same RAM in my older Compaq laptop, and it just runs at 1066MHz as per nonmal.

What I am saying is the risk of failure is very low after the RAM is flashed, as it required the use of the M17x R3 BIOS to enable a XMP profile. e.g. if it didn't boot once XMP profile 2 was enabled, then just pop out the motherboard battery for a few second.

Make sure you backup your original SPD.

I have Micron based RAM in my other R3, but that is due to be return in a couple of days, so I don't really want to mess with it.

I have flash some cheap no name brand called Strontium, it really budget, but uses the same Hynix chips. It will do 1600MHz XMP, but will fail under any load, so not stable. But when running without XMP, it is no different to the original SPD running at 1333MHz.

 

So I can flash my micron ram and potentially run it at 1600 with almost no risk? Meaning, I can flash it back if it doesn't work out as well as the hynix?

Hmm, my othe 2 sticks are GSkill. I could flash those just the same though, right?

 

^^This, and what's the method for Samsung ram?? Also, do I need to do this stuff if I'm doing regular everyday stuff? Will I notice a difference in gaming?

 

You'll not notice a single difference while working on everyday stuffs and not even in games.

I tried the above process and now my stock RAM is running at 1600MHz. But only benching with Hwinfo32 benchmark feature, I saw the benching scores for RAM was quite higher than earlier.

 

If I wanted faster performance, it'd be better to just upgrade to like 6 or 8gb, right, instead of upping to 1600mhz?

 

Doing this allows you an upgrade without throwing away your old RAM. Your old RAM becomes your upgrade, providing it will do 1600MHz
Anytime you don't like it (for what reason I would not know) you can just turn off XMP in the BIOS.
There is nothing to lose and everything to gain.
Memory modules with Hynix chips get a tick from me.

 

Sec, how do I check if my ram can do 1600 besides trying? I don't want to fry 'em.

 

hey T2050, can you make a little tuto how to do it plz
I got so many ram so if it fail I don,t care^^
Edit: i found EVGA SPD and your SPD modded in another thread but I'm unable to flash :/ i can read add but no flashing.. you know why?

 

Bump?

I would love to know how you did this man.
