New memory not working in old Motherboard ( H57H-am2 v2.0 ) HELP

[raphaelaz]

Hi,
I had 4x 2gb ddr3 / 10600 unbuffered 240pin ram memory installed in my acer m5910, everything worked fine (stock)
Wanted to upgrade my computer and bought 4x4 4gb of same ddr3 for total of 16gb

http://www.amazon.co.uk/Corsair-CMX16GX3M4A1333C9-Performance-Desktop-Memory/dp/B0054KPK9C

After installing 4 new sticks acer didnt even boot up, tried with different ports and then with only 2x4 sticks and same thing happened.
Then i installed my old 4x2gb memory back everything worked again fine.
Thing is my motherboard should support 16gb max : http://www.findlaptopdriver.com/h57h-am2-v2-0-motherboard-specifications-20h090713/
So whats the problem?

BTW my bios version is p01-a3... on acer page i could download and flash it to p01-a4 if that makes any difference ? FROM SITE: Updates CPU Module from 8.00.15_CPU-i7_01.0C to 8.00.15_CPU-i7_01.0F and Disable Intel Enhanced Debug mode.

The acer site does not even list compatible memory product numbers. So that was no help.

However, crucial.com does.

Based on what that says, I believe 2 of these kits will get your 8Gb of memory for that machine.

thank you for answer, is there any performance boost from using 2x4gb sticks instead of 4x2gb sticks?

OP, are you sure that the RAM is compatible exactly?

 

[raphaelaz]

Only thing i didnt find is pin number anywhere, some sites say its 200pin or 204pin on corsair 4gb. Ram i use now is 2gb and 240pin, could this be it?

UPDATE: found its 240pin in shop where i bought it, so not the problem

Prebuilts can be very picky with what DRAM they run with, might try first resetting the CMOS, then trying 2 of new sticks, if that's good then try adding the other 2. Might also be the CPU can't handle 4 sticks

Crucial knows memory. Their parent company is Micron. They make the memory in their own fab. They are partners with Intel on NAND chips for SSD's. They are the only American fab company that makes memory left. They bought Hynix when they went bankrupt a few years ago. Hynix was another memory manufacturer.

When they say Crucial memory will fit a specific model of motherboard or machine, it will.

My processor is stock i5 650 not overclocked. Is this corsair 4x4gb kit compatible with new ddr3 motherboards btw? I plan to upgrade in about a year and hope its not complete waste of money if its not working with old mobo.

Simply saying DRAM will work on a mobo is only part of the whole process, i.e. will it work, Yes...you say a 2x2GB set and say get two - mixing DRAM, even of the same exact model is a crapshoot, there are no guarantees. And here you you suggest 1600 and 4 sticks, which also can be a problem, the CPU is not OCed and is only rated to 1066/1333 which seldom can run 4 sticks of 1600 (at 1600 anyway), this is also a prebuilt, prob with a locked BIOS that may not be able to even set up 4 sticks of native 1600 down to 1066 or 1333. There's a lot more to selecting DRAM than simply looking at a list, will it work with the mobo, Yes. Here will it worked with a locked CPU (prob not at 1600), and the MC is more the determining factor than the mobo. Can you make adjustments to the DRAM (voltage/timings) if problems? Again prob not as prebuilts normally have a locked BIOS

Its prebuild acer m5910 with h57h-am2 v2.0 with bios p01-a3 , no voltage or oc options in bios, only ram related option is memory remapping and i have it enabled.
Would flashing it to p01-a4 (latest available) help at all? Or some tweak program?
thx

Is the BIOS locked? Most are

 

[raphaelaz]

No options for DRAM adjustments if you mean that. Dont know if it means its locked, i can still change settings like VT / memory remapping / EIST / turbo boost and check temperatures but thats about it.

 

[Tradesman1]

Doesn't sound like much you can do, could check for a BIOS update but wouldn't hold my breath

In over 30 years of buying memory, and some of it from Crucial, I have never had any issues with Crucial memory, and during that time, I would guess 4-5 systems got multiple kits of Crucial memory to move to a higher amount of memory for that client. None had problems.

That was part of the reason I went there searching for memory that was compatible with this laptop. And when I put the model number in, Crucial knew what worked instantly. Unfortunately, they only list 5 kits, none have 4 sticks, and only 1 amounted to 4Gb. So there is only one path to 8Gb for him.

Is there possibility of bricking the motherboard with bios update? I will download it from acer official site and everything looks compatible.
