Hey all. I relatively new to OC and watercooling. Just put together a new water cooled rig and had a blast, but I am running into a problem and I need some help.

I was overclocked on air previoiusly 20x multiplier at 200Mhz. ( I know, I know the 20x multiplier is junky but it worked for a year and was rock solid stable in all tests). After the build I upped the multiplier to 21 (turned on turbo) and proceeded to overclock as usual. I haven't changed anything other than water cooling the graphics cards, MB and CPU and now I am having stability issues.

In particular, my system is freezing (not BSOD) in both prime 95 and memtest (at about 86%). I can't complete the test and I can't see any results. Ame thing for prime 95, just freezes. I can reboot into windows and it will work fine, I can game and its fine but I load test and it will freeze. I have tried upping the vcore to 1.5 volts and it will do the same thing (only at a higher temp tongue.gif). I am at a loss. Any ideas where else I should be looking? Uncore? Pull memory one at a time?

Bios setting below and system in my sig. Thanks for the advice in advance.thumb.gif

CPU 21x
CPU freq 200Mhx
Uncore freq 17x
Spread spectrum off

Memory 8, 8, 8, 24, 59, 1t (mem rated 9,9,9,25 at 1866 on 1.65 v, running at 1600 at 1.65v )

Voltage
Vdroop off
vCore 1.36875
cpu vtt +300
CPU PLL 1.85
QPI PLL vCore 1.35
IOH vCore 1.4
IOH/ICH/IO voltage AUTO (1.5)
ICH vCore AUTO (1.1)

Let me know if you need anything else, Speedstep, CxE, virtulaizaiton are all disabled.
