Tried ioh @ 1.4: prime ran for a few hours and then got a bsod 101. Bumped vcore up to 1.34375 and re-ran: locked up again.
These lock-ups -- I've been assuming this is a memory / timing issue. Is that a reasonable assumption?
bump ... any suggestions?
I was able to run prime95 with the settings above and a custom blend with 20GB allocated, but then got a rounding error. I bumped vcore up a notch but things seems to be more unstable now with more frequent lockups.
I bumped IOH up another notch to 1.325. Prime95 ran for 8 hours before locking up again. IOH does seem to be helping so I've upped it again to 1.35 and started another run. My settings are now:
bclk: 160
mult: x26, turbo enabled so max mult is x27/x28 (4322.6MHz in eleet)
memory speed...
So far, good. Max cpu is upper 60's. The hot PWM is also upper 60's / lower 70's (C).
Ran dual IBT for 6 hours, no problems. Making a prime95 run now.
Update: and prime locks up after a couple of hours ... /sigh
Ran my custom prime95 with ioh at 1.3 and got a bsod 101 after several hours. Retried at the same settings with 2 IBT custom and got a lockup within about 10 minutes.
bsod 101 is usually vcore, right? I can try pushing that up a bit and see what happens.
UPDATE: pushed vcore up another...
I could really use some help with overclocking this SR2.
2x x5690 cooled with H100's (eventually I will add custom cooling).
24GB of of HyperX 1600 9-9-9-27, 6 sticks in the red slots (KHX1600C9D3K3/12GX)
2x evga gtx 680 on air. Eventually I want to go to 3x with a custom water loop...
My thanks to Rich as well. I used his tech tray as a home for my 4P folder / file server

and it couldn't have worked out better. I've picked up a second tray to use as a test bed for a SR-2 build I've started.
I agree completely on "no such thing as too much radiator." I'm thinking about a second pump because my flow rate is down around 1gpm right now which is ok but not great. I'm sure that any additional radiator will drop that below 1 gpm which is less than ideal from what I've read.
And, the...
Thanks, Biffa. How do you like that XSPC top? Anyone reading this use the Swiftech top?
I'll do a little more digging on the dual pump tops as an option. It would make my plumbing alot easier if I didn't have to add a second pump in the middle of the loop.
I currently have MCP35X -> MCR420 w/ 8x GT AP15 push/pull -> 4x Koolance 370SA and temps max out @ 38-42C with ambient @ 27C now that I've backed off to a 226 refclock. Flowrate is around 1 gal/min.
Is it worth adding more pump / res given that most of procs max out around 225-226? If I do...
Wow ... I wish! You say 'had'--you got rid of them? I've got my four on water (wanted to do something different) and was debating a little extra cooling. Maybe I will give that a try...
Yea, I realize that I am flirting with the top end of the 6100 family so my OC would be starting from a higher CPU clock. I was just a little surprised that 13%OC was all I could get. Still, I guess 11:30 TPF on a 8101 isn't too bad ;).
Yep, I'd seen tear's post, though I'm not completely...
Greetings! I'm a n00b when it comes to AMD & 4P rigs so I hope someone can answer a few questions. I've put together a 4P rig with a SM H8QGL-IF+, 4 6180SE's, and 32GB of Ballistix ddr3 1600 memory (1.5V 8-8-8-24). I've flashed the [H] Bios and have been testing overclock settings and...
