During the time we had the Ripjaws X kit in our hands, we were in the process of reviewing the iBuyPower BTS-11 gaming rig. We figured, “Why not test the RAM using the BTS-11?” So that’s just what we did. For those of you who didn’t read our review of the BTS-11 (shame on you; make with the clicky!), the BTS-11 is fitted with a Gigabyte P67A-D3-B3 motherboard, and an Intel i5 2500k processor.
We started out by utilizing the XMP profile, which set the RAM at the recommend speed of 1866MHz, timings of 9-10-9-28, and command rate of T2 with the DRAM voltage set at 1.5v. The kit ran stably, with no issues. Changing the command rate from T2 to T1 also yielded positive results. We tried running the RAM at tighter timings, but it seems the sticks only liked a minimum of CAS 9. This was a bit disappointing, but definitely not a deal-breaker in our eyes.
Achieving 2133MHz was possible by running the sticks with the timings at 9-11-10-28, T2, at 1.56v. Prime 95 blend test was performed for approximately twelve hours which resulted in no errors. We also discovered that we could run the sticks at the same speed with DRAM voltage set at 1.50v. Impressive. We ran a number of benches, as well as games like Battlefield: Bad Company 2, HoN, and Crysis 2 with the modules running at the lower voltages, and they passed without fail. Achieving these same timings at command rate 1T required a little bump in QPI voltage.
Now for what most of you have been waiting for… How high could we push the overclock on these sticks?
For this test, we used a Gigabyte P67-UD3-B3 board this time around, fitted with an Intel i7 2600k (point the first: iBuyPower wanted their rig back; point the second: we’d have felt really bad if we’d fried it in a massive overclocking fireball… these are the kinds of compromises we make behind the scenes. It’s not all hookers and blow over here, guys).
The max overclock achieved was 2155Mhz, with timings at 10-12-10-28 with a command rate of 1T at 1.6v DRAM, and 1.2v QPI. We likey!
