6GB Patriot Viper II PV236G2000LLKB Elpida MNH-E Hyper

I got myself a nice set of Patriot Viper II 3x2GB PV236G2000LLKB. These sticks are rated for PC3-16000 at the tight timings of 8-8-8-24@1.65v, so with those ratings we all know underneath the heatspreaders lurks Elipda J1108BASE Hyper chips. I'm not sure if these are MNH-E or MGH-E but I'm guessing the latter considering they came out about June~July 2009 which is when all the high end kits that had been halted were reintroduced with MGH-E. Anyway, here is the obligatory RAM pr0n





Test Setup:
Intel Core i7 920 D0 (Batch # 3946A172)
Gigabyte X58A-UD3R BIOS F5
Corsair CMPSU-1000HX
Thermalright Venomous X + 2x Scythe SY1225SL12M 1200RPM fans
Windows 7 Ultimate x64



DDR3-1600 7-7-7-24 1T 1.50V 21x133BCLK 8x HyperPi 32M


I decided to "ease" into this kit so I can be gradually more and more impressed with its performance. With that said, I stuck to the stock settings on CPU and just ran these at PC3-12800 CAS7. Not much of a test I know, but they were able to do this at 1.50v BIOS set. I got the idea from the MGH-E based SanMax SMD-6G88NP-16F(H)-T kit sold in Japan that is rated for this speed, timings, and voltage and which are impressive overclockers in their own right. So far, these seem on par.





Popped the heatspreaders off quite easily just to verify which version of Elipda Hyper this kit uses:




Uh oh. These are the original auto-RMAing MNH-E Hypers I wonder how long I can expect this kit to last. Hey, at least they use some nice Kunyu 8-layer PCBs!

DDR3-1600 6-7-6-18 1T 1.64V 20x200BCLK HyperPi 8x 32M


At long last, I have a kit that can do DDR3-1600 with 6-7-6-x timings without having to shove 1.70v+ in them! I'd run this 24/7 if I weren't afraid of the Hyper chips they use dying on me Oddly enough, the latency in the Everest test seems about 2ms slower than other results I've gotten at the same settings with my other kits. Could just be a random thing.




I showed Everest's readings for the voltages because I'm not clear what the true reading is for VDIMM on this board. BIOS set was 1.64v, my previous testing showed that the board overvolts by 0.05v but Everest thinks it's undervolting. Perhaps my DMM readings are off? I used the ground pin of a 4-pin molex for ground whereas I've read other places used a fan header pin or a screw whole. Gah who knows.

DDR3-2000 7-8-7-24 2T 1.76v 1.55VTT 20x143BCLK


It's so nice to finally have a kit that can do 7-8-7-x at 1000MHz! I attempted to go all out at 20x200BCLK but I couldn't get it stable enough, so I decided to give the CPU a break and just test out the memory. Giving it a bit more VDIMM and bumping up the VTT to 1.55v BIOS was enough for HyperPi 8x32M stability. I really hope this kit lasts


HyperPi 8x32M




SuperPi 32M

Nice, looks promising on voltage side! FYI, MNH-E hyper don't mean more prone to failure, it was just certain week batches of MNH-E Hyper that had issues - although 0911 was well within those batch range not sure, but hey I wouldn't worry if you want hyper tight timing performance, there's no other ics for such

Updated post #2 with some PC3-12800 C6 action.

Nice results, tried a few more runs of everest ? As it can vary between runs. Also tried everest bench at 1.66v vdimm too ? Sometimes not enough voltage = less bandwidth reported even though other benchmarks like super pi/hyperpi pass 32M tests.

Congrats there, definitely need to push the bclk and cpu clocks, high ram clocks are wasted without some nice 32m PI action
