A couple months ago I sussesfully Overclocked my i7 920 to 4Ghz. I ran it at that for a few weeks and decided I wanted to cut the noise down a bit, so set it down a notch to 3.8Ghz.
Recently, with the stress of exams etc, I decided I needed a little bit more stress
, so I decided to get the memory speeds running at 1600Mhz. Prior to this I had ran them at 1260Mhz or less because I have never got it Prime or LinX stable with a higher frequency.
After a lot of tinkering with settings, and I mean a lot (+ 20 attempts atleast), I finally got the PC through a 20 pass of LinX at 3.8Ghz and 1560Mhz DDR3 speed with max memory used, using the following settings :
Vcore 1.195
VTT 1.38
DRAM auto (only seems to work on auto)
everything else on auto
Ram timmings - 8-8-8-24 T1 @ 1566
BCLK 181 x 21
It was only when I played around with the advanced RAM settings (something which I am lead to believe should be unessasary when OCing on Biostar boards) that I got this through LinX.
Passed 3DMark06 and HeavenBenchmark 2.0.
Loaded up some multiplayer L4D2 (always found this to be a good testing game, and fun at the same time). At irregular intervals in L4D2, the screen would freeze up and the sound would loop. This would happen for 2 to 5 seconds and then the game would resume normally. After a few of these events the game froze up completly, and 10 seconds later crashed to desktop (another time I had to force close with crt-alt-del).
This process was repeated in a few games, before I decided to temporarily put it back to RAM 1140 Mhz.
The fact that the game glitches like this seems to suggest a QPI/Memory problem, and the fact that it can play for a while suggests the system is unstable, but not far off-stablity.
Any veterans have any clue as to what could be causing these weird in game issues? Happens in Napoleon Total war aswell. Could it be an I/O Issue, something need more volts?
The memory btw is OCZ Platinum 6BG 1866, which ofc is proving to be a nightmare to run anywhere near 1600, even at stock. Biostar x58A mobo.
