Introduction:
I received a sample from G.Skill around two weeks ago and I've finally had the chance to finish up my review on this exciting new memory kit. When I first received this kit, not much was known about it, and frankly I assumed with it's timings that it had to be Micron. I was quite surprised after asking around that the kit contained new Promos IC's.
It's great that memory manufacturers have been able to find a performance substitute to the Micron based IC's. Micron IC's are extremely expensive, and while they perform well, they aren't the only game in town, and I suppose that's what G.Skill and other manufacturers are trying to prove with these alternative IC kits. Now, without further ado, let's get on to the review.
The Memory:
-------------------------------------------------------------
Test Setup:
Intel Core 2 Duo "Allendale" E6400 - Lapped
Asus P5B-Deluxe rev1.03G - Stock, Bios: 908beta
2x1GB G.Skill F2-6400CL4D-HK
BFG GeForce 7950GT 512MB
OCZ PowerStream 600w
Cooling:
CoolTechnica AQX MP-05 SP LE, Swiftech MCW60, Black Ice Pro III, Swiftech MCP655, 7/16" ID
120mm Yate Loon @ 12v over memory
-------------------------------------------------------------
Testing Methodology:
The testing process I used is quite simple, and I'm guessing quite close to the same procedures the bulk of you use to test your new hardware. I simply, hopped in bios, set the lowest reccomended voltage by G.Skill themselves, which was 2.0v, and set the stock rated timings of 4-4-3-5-3. I then proceeded to exit bios and enter Memtest v1.70. I tested using tests 1, 2, 4, and then 10 loops of test 5 before moving on to the next speed up. I worked in the 2:3 ratio and moved up 2MHz on the FSB at a time. I also used full vFSB and vMCH voltages the entire time to ensure the chipset wouldn't hold me back. I increased clock speed until I would error in memtest, then I'd back down 1MHz on the FSB at a time until the errors disapeared, then I'd log my results and push up the voltage another notch and do the same testing with that. Once this was done, I entered windows and began testing in Orthos using 2hr test periods to attempt to document some level of stability, atleast higher than SuperPi 32M, while still maintaining my social life and other responsibilities.I experienced fairly large discrepancies at some points throughout the Orthos testing between what Orthos was saying was stable and what Memtest had previously passed. This just goes to show all those of you who think Memtest is the end all be all test suite for memory, it isn't, it's a starting point.
The Review:
Each piece is separated by timings and voltages. I started with 4-4-3-5-3 and ended with 5-5-5-15-5 to achieve maximum MHz.
-------------------------------------------------------------
Timings: 3-3-3-5-3
2.35v
2.4v
No Gain, Actually Lowered Stability.
2.45v
No Gain, Actually Lowered Stability.
Timings: 4-4-3-5-3
2.0v
2.1v
2.25v
2.35v
2.4v-Higher
No substantial increase in stability or clocking was achieved with voltages above 2.35v. It's quite apparent that these sticks like to stay in the lower voltage zones, especially when compared to Micron D9.
Let's see how they do with 5-5-5-15-5 timings shall we?
