Yo!!
I was looking for latency "elasticity," and I've got these Corsair, 2x2GB DDR2-800 [4,4,4,12] modules installed. All my embarrassing panic of last week, well known now on these forums and which I may not be able to live down before I stroke out with an embolism, is behind us . . . behind me, that is.
The voltage spec on these is 2.1V. I told the RAMGuy that I had them set at 2.075V and the sensor was reading 2.09V. I asked if 2.1V was the warranty-maximum, and that's confirmed. He said "JUST set 'em to 2.1V, and don't worry, be happy . . . fahget-about-it!"
Now I'm stress-testing with the 2.1V setting, because bumping up the VCORE had no appreciable effect: PRIME95 errored out on me after 2 hrs, 49 min, when the previous run at the lower VCORE errored out after 2 hrs, 42 min.
I don't want to loosen the timings on these (from 4,4,4,12), and in fact, I want to try tightening them down to 4,4,4,10. I don't want to move the RAM voltage up above 2.1V, either. If this is the limit, and I can't get beyond DDR = 810 Mhz (it's now at 820) without over-volting or loosening the timings . . . . then . . . that's it.
I may have mentioned here earlier -- in some thread -- about some DDR-400 OCZ Platinums I had in an older system, where you could keep the voltage below the warranty spec, while boosting the DDR speed from 400 to 452 with the same timings of 2,3,2,5.
Does anyone have any experience with these, while I look for a review where they put them through their paces?
EDIT: I found some good reviews for this TWINX CAS4 DDR2-800 DHX 4GB kit -- at OverClock3d and Guru3D. In order to put these bad boys through their paces, they twist up the voltage from the spec 2.1V to 2.3V, and these suckers push past 1000 Mhz.
But I'm a Crucial Ballistix victim -- of trying to keep the Crucials just 0.025V below their warranty maximum. The reviews don't offer any warning about their test voltages, yet they both tout Corsair's lifetime warranty. Figure I'm just being cautious because I "wasn't supposed to buy these things" when I got panicky about BSODs and my G.SKILL DDR2-1000 4GB kit, which G.SKILL is sending back to me at my request (now that I see that my problem was an undervolted CPU_VTT, and I'd not got used to BSODs with this motherboard running PRIME95 -- got through some respectable over-clocks on it last year that weren't into the 400 Mhz range.
Maybe I should just twist 'em up to 2.15V and see what I can squeeze out that way. But you'd think the reviewers would stick to the safe voltages, when other memory reviews I've encountered are very sensitive to it.
Any ideas before I step across the line into the realm of uncertain risk?
