Hi,
This is a complete rookie question, need insight of experts or gurus out there.
I have G750JX TB71 model. I ran CPU Z test on machine and found following details for RAM -
Memory SPD
-------------------------------------------------------------------------
DIMM # 1
SMBus address 0x51
Memory type DDR3
Module format SO-DIMM
Manufacturer (ID) Hyundai Electronics (AD00000000000000)
Size 8192 MBytes
Max bandwidth PC3-12800 (800 MHz)
Part number HMT41GS6AFR8A-PB
Serial number 1D663017
Manufacturing date Week 20/Year 13
Number of banks 8
Nominal Voltage 1.35 Volts
EPP no
XMP no
AMP no
JEDEC timings table CL-tRCD-tRP-tRAS-tRC @ frequency
JEDEC #1 5.0-5-5-14-19 @ 380 MHz
JEDEC #2 6.0-6-6-16-22 @ 457 MHz
JEDEC #3 7.0-7-7-19-26 @ 533 MHz
JEDEC #4 8.0-8-8-22-30 @ 609 MHz
JEDEC #5 9.0-9-9-24-33 @ 685 MHz
JEDEC #6 10.0-10-10-27-37 @ 761 MHz
JEDEC #7 11.0-11-11-28-39 @ 800 MHz
DIMM # 2
SMBus address 0x53
Memory type DDR3
Module format SO-DIMM
Manufacturer (ID) Hyundai Electronics (AD00000000000000)
Size 8192 MBytes
Max bandwidth PC3-12800 (800 MHz)
Part number HMT41GS6AFR8A-PB
Serial number 1D263032
Manufacturing date Week 20/Year 13
Number of banks 8
Nominal Voltage 1.35 Volts
EPP no
XMP no
AMP no
JEDEC timings table CL-tRCD-tRP-tRAS-tRC @ frequency
JEDEC #1 5.0-5-5-14-19 @ 380 MHz
JEDEC #2 6.0-6-6-16-22 @ 457 MHz
JEDEC #3 7.0-7-7-19-26 @ 533 MHz
JEDEC #4 8.0-8-8-22-30 @ 609 MHz
JEDEC #5 9.0-9-9-24-33 @ 685 MHz
JEDEC #6 10.0-10-10-27-37 @ 761 MHz
JEDEC #7 11.0-11-11-28-39 @ 800 MHz
The frequency of single module suggest operating at 800 MHZ. Now, I was looking for RAM upgrades and found
details on CORSAIR Vengeance , supposedly high performance module which have following details -:
1 x 8 GB DRAM Structure
SO-DIMM Memory Module
DDR3-1600/PC3-12800
9-9-9-24 CAS Latency
1.5 V Specified Voltage
204-pin Configuration
Single Channel Memory
Frequency 1333 MHz (Specified), 1600 MHz (Test)
2 changes noted
#Change in voltage 1.3 V to 1.5 V
#Change in Frequency. 800MHZ to 1333MHZ
Now I know i need to have all RAMs at same voltage. Hence would need to replace both.
My query is whether these RAMs are supported on G750JX and this upgrade is really worth it . OR it just a cosmetic change and
I am burning hole in my pocket.
Thanks in advance.
