FEATURED G.Skill RipjawsX 2x8GB DDR3-1866 F3-1866C9D-16GXM

Yesterday I could test new G.Skill RipjawsX 16GB DDR3-1866 9-10-9-28 kit. I didn't have much time but I wanted to share anyway ... maybe someone is curious how it's working

For tests I will be using i7 [email protected] and Gigabyte Z87X-OC motherboard.

G.Skill as usual programmed 2 XMP profiles and both are nearly the same. Little differences were made for compatibility purposes as this memory is dedicated for nearly all available platforms from Intel and AMD.

Since both profiles offer the same performance then I will show results only on one XMP.

Latest CPU-Z versions have some problems to read profiles so better is to use something like MemTweakIt to check timings.
Here is screenshot from Mem Tweak It:


Timings are pretty tight for a new 16GB kit.

As I already said I had this memory for one evening only and I didn't have much time or even good light so photos aren't best ... anyway I think that all know how RipjawsX look like







This memory is actually scalling the same as Crucial Ballistix 1866 or even like previously reviewed on the Overclockers Super Talent 1600 memory. Both of these kits are based on Micron IC.

If it's hard to read then number on the IC is " E 648B243 3 ". Modules are double sided.
SN is telling us it's Nanya IC but somehow it's overclocking better than other Nanya based kits I had a chance to test.

Testing

Stock 1866 9-10-9-28 2N / XMP 1.50V
Standard XMP profile , as I already said both profiles are about the same so performance will be also the same.




Max stable OC - 2200 10-11-11-30 1N 1.65V
Maximum clock that was able to pass HyperPi 32M and any other test that I was running. It's possible to slightly lower voltage but not so much. At 1.50-1.55V memory is booting without issues at 2200 CL10 but isn't passing any higher load test.




Max benchable OC - 2600 11-13-12-34 1N 1.65V+
Maximum clock in quick benchmarks like AIDA64 or Maxxmem. It's crashing in HyperPi 32M in about middle of the test.
It's pretty interesting that memory is able to boot fine at 2600+ 1.65V but isn't able to run stable above 2200. I was trying voltages up to 1.8V without any difference.



Max valid - 2666 11-13-12-34 1N 1.70V

Pretty good result for DDR-1866 kit especially that I didn't have to raise voltage too much. Higher voltage didn't help and booting at 2800+ was impossible.

Bit late to this thread I know... lol... but are these IC's same as found on G.Skill F3-12800CL8D-8GBXM kit only binned higher?

What's the serial number on them? First 4 or 3 digits are year and month made, 5-8 digits is the Ic. I believe your sticks are Elpida but the serial number will let us know. If it's 0640 it Elpida.

No idea, don't wanna try and see either, risky removing heatspreaders..

Sorry I wasn't more clear not the one on the Ic, Look on the heatspreader the white sticker has it on it.
See these sticks for example First 4 numbers "1240" mean they were made 40th week of 2012, next 4 "2400" Hynix Ic's.

Thanks Mandrake4565, I'll look into that. Cheers.
