Memory upgrade for HP Pavilion G6-2005AX

HP Recommended

As the usage started getting heavier, I am finding it difficult with 4 GB RAM and urgently need to upgrade to 8 GB.

 

The original HP OEM RAM is A-Data AM1U16BC4P2-B19H 4GB DDR3 SO-DIMM PC3-12800S DDR3-1600 (11-11-11-29 5-40-13-6).

 

Already ordered G.Skill SQ DDR3 4 GB (1 x 4 GB) Laptop RAM (F3-12800CL9S-4GBSQ) CAS Latency 9-9-9-28 @ 1.5 V. I have very good experience with G-Skill and so going for it. I also considered Corsair Vengeance DDR3 4 GB (1 x 4 GB) Laptop RAM (CMSX4GX3M1A1600C9), CAS Latency 9-9-9-24 @ 1.5V.

 

There is an ongoing issue that is unsolved by HP- that is DOWNGRADED MEMORY SPEED from 1600 to 1333 MHz after F.14 BIOS upgrade. See the thread http://h30434.www3.hp.com/t5/Other-Notebook-PC-Questions/memory-speed-is-reduced-from-1600mhz-to-133...

 

Will this upgrade work or any better alternative available?

Hi,

 

Both specs from G.Skill and Corsair won't work on your machine. You need 1.35v and CL=11 to match. Please try the followning re;iable vendor:

Thanks for the immediate reply.

 

My observation is that never my HP Pavilion G6-2005AX (Made in China) has shown 1.35V and neither have I come across any desktop also with 1.35 V. I am from India and your reference web page pertains to the US.

 

I ran the Crucial system scanner Tool and gave the same result as you have given. But curiously, it does not give the full specifications current existing RAM, particularly the voltage and CAS Latency as does CPU-Z and lists price for two sticks prominently ignoring the fact that a possible upgrade requires only one more.

 

The search for all suitable RAMs gives only 1.35V sticks. There is no 1.5V model at all on that page as suggested replacement. 

 

Perhaps there is some geographical specificity for benchmark/ practice. I presume that it could be because of the higher cost for low voltage high frequency RAMs.

 

On checking with wiki http://en.wikipedia.org/wiki/DDR3_SDRAM the absolute maximum specified breakdown voltage (for design) is 1.975V and even for mission critical servers the suggested maximum voltage is 1.575V. 

 

All I can say is that the BIOS of the laptop is locked and I have never tried to change any voltage, nor is it possible, I guess. 

 

The Current A-Data AM1U16BC4P2-B19H 4GB DDR3 SO-DIMM PC3-12800S DDR3-1600 Timing Table as per CPU-Z Ver. 1.67.1.x64 is as follows:

Based on this information I have chosen G-Skill SQ DDR3 4 GB (1 x 4 GB) Laptop RAM (F3-12800CL9S-4GBSQ). See the Specifications at http://gskill.com/en/product/f3-12800cl9s-4gbsq.

 

Do you mean to say that the system will crash and not work at all with two RAMs of different companies but with matched specs? I have done it before with desktops earlier and it has worked.

 

Thank you very much for your information. Further input is always welcome.

So far no issues. I am using dual boot with Windows 8.1, which I immediately upgraded, as I got a pre launch offer for the HP laptop purchase and Ubuntu 14.10.

Dear Blakeh, 

 

I think you asked about adding Corsair RAM along with ADATA (Stock). 

 

Two sticks of different manufacturers should work, as long as the set RAM voltage and CAS latency values matches. It should be lesser than the stock RAM values and not more, else the slower setting will be the default, I presume. But RAM manufacturer encourage or corroborate it officially, for their own reasons. 

 

I communicated with GKill tech support, who suggested that both the RAM modules should be of the same make, which again I guess, would be the answer from Corsair, as well. 

 

From my experience of 1year 1 month, ADATA and G-Skill are mated without any issue. Please refer to specifications on my earlier posts. 

 

It is worth your while to try and match two different manufacturer's modules. If it gives any problem (only due to some non-standard issues) you buy another of Corsair and pair it as Plan B. 

 

I presume that ADATA is your stock RAM and is not easily available and also is expensive. 

 

Bottomline- if voltage and latency matches, any two RAMS should perform flawlessly, in my opinion. 

 

More input welcome.

Dear Blakeh, 

For this configuration 2x4 GB is more than sufficient, functionally. More could be overkill. With 8GB RAM I could work with SolidWorks without any lag. If you put more memory and use heavy stuff, you may end up with heating issues. With 8GB and a cooling pad I am able to work for hours together with the system being on all waking hours and sometimes up to 48 hrs non-stop for tests, upgrades etc.
