G.SKILL RipjawsX F3-12800CL9D-8GBXM 8GB Memory Kit
1600Mhz 9-9-9-24 1.35V


Recently OCDrift.com was contacted by Ideal Tech, one of the leading PC DIY reseller located in Pandan Indah, Kuala Lumpur to test the G.SKILL RipjawsX F3-12800CL9D-8GBXM 8GB Memory Kit. G.Skill is a computer hardware manufacturing company which produced world-class Memory with the most OverClocking records @ HWBot.org. The company’s main target is the OverClocking community and produces a variety of products. Apart of Memory, G.SKILL also produces SSD, Flash Drives, and cooling gears. As for this RipjawsX F3-12800CL9D, they comes with two different colour which is red and blue.

The Memory sporting 6 layer PCB. We expected 8 layer PCB but 6 layer should be sufficient for Entry-Mid level Memory Kit like this particular one.

The Memory IC
As usual, OCDrift.com like to show our readers the Memory IC used for our Memory review. Therefore we pried the heatsink to check what chipset used and check it’s characteristic. Apparently this module is equipped with a relabeled chipset, F146V8CR840G


From what we gathered, this chipset is similar to the one found in G.SKILL RipjawsX DDR3-1333 7-7-7-21 1.5V 8GB Memory Kit, the F139V8CR942R.


According to i4Memory.com, this particular IC possibly is a Elpida B_SE but we couldn’t find and hard evidence on it.

Test Bed


Stock Setting Test
Here’s a screenshot for Prime95 (custom setting). Basically if there’s any instability issue, error will appear in less than 10 minutes.


Default (auto)
In the BIOS, we set the Memory Setting to Auto with regards to speed, timing and voltage. The Memory run at 1600 11-11-11 1T @ 1.35v. It’s running on a very loose timing but at 1T Command Rate. Normally in Auto setting for various Memory it is set at 2T Command Rate. CPU-Z was buggy so we used the Aida64 Extreme Edition instead.



XMP Optimization
Enabling the XMP, resulting in DDR3-1600 9-9-9 2T @ 1.35V





Overclocking
In OverClocking this G.SKILL RipjawsX F3-12800CL9D-8GBXM 8GB Memory Kit, we couldn’t boot at any voltage ranging from 1.35v to 1.55v for 1600-->1866 divider at any loose timing (9-9-9, 9-10-9, 9-11-9, 9-10-10, 9-11-11, 10-11-11, 11-11-11). However we tried using another different method which is increasing the HTT Clockspeed and it worked! Below is some of the result we managed to get.

Attempt No.1
1600 8-8-8 1.35V passed Hyper Pi 8M but failed Prime95




Pump the VDimm to 1.375V and it passed Prime95. Not bad for 8-8-8 1T with 1.375V only. Unfortunately it couldn’t boot at CL7 (7-8-8, 7-9-8, 7-9-9) with any voltage (1.55V max – since this is 1.35V module, we didn’t try 1.65V)

Attempt No.2
In order to hit DDR3-1700, we had no choice but to loosen up the timing a bit from 8-8-8 to 9-9-9.



Attempt No.3
DDR3-1800 9-9-9 1T, failed Prime95 any voltage below 1.45v


Attempt No.4
We managed a DDR3-1840 result with CL10.


Final Attempt
The best we could achieve with our limited OverClocking skill with this G.SKILL RipjawsX F3-12800CL9D-8GBXM 8GB Memory Kit is DDR3-1870 via HTT OverClocking.
Do take note that we couldn’t achieve this via Divider.
1870 10-11-11 1T @1.535V


Conclusion
G.SKILL RipjawsX F3-12800CL9D-8GBXM 8GB Memory Kit is a Entry to Mid level Performance Memory. There’s nothing much to shout about judging on the best result we obtained. It would be nice it could hit DDR3-18xx @ CL9 since some of the value memory out there can do DDR3-1600 8-8-8- to DDR3-1866 9-x-9. But we do love the fact that this Low Memory kit managed to do DDR3-1600 CL8 and a slightly higher voltage compared to stock, which is 1.375VDimm.

nice info TS, TQ

ive ordered this RAM just now..

but my mobo p55us3l only support 1333mhz..need to learn some tweaking to get it to 1600mhz..any advice?

will receive the items next day maybe =)

thanks for the info TS! TQ

hows you ram?
i'm not familiar with any 1156 mobo.
try post your bios option for the ram speed here

here it is






its all stock maybe..i changet to profile1..doesnt really understand..

simply enable the XMP (profile1/ profile 2) would be the best and simple way
but your timing there a bit loose... try set manually to 9-9-9 instead of 10-10-10 now
try open the DRAM timing, set the timing manually

done it..thanks!

I wouldn't know how good will it be. But it should able to perform good. I bought 2 sets of 8GB in which comprise 16GB.

What's the benefit of having lower voltage (1.35v) to run on DDR 1600mhz?

Thanks

the only benefit that i can see is, 'lower voltage' compare to normal 1.5V
thats all. low voltage = low temperature.
OCability, depends on chip. i've tried very few only from 1.35V range, mostly suck in OC

hi bro..sorry to bring this post..

i cant make my timing to 9-9-9-24 anymore..it wont boot

im on Profile1 and others are all auto..this is what i got




as u can see..my SPD result, very close to what your last attempt result..how is it posible?

but mine is 2000Mhz?

--> update attempt 2..i can boot now by changing the SPD to 8.0



maybe this ratio 2:8 better? i set the memory voltage to auto..scare to manual adjust voltage atm afraid cant boot up again
