970BE OC - Suggestions?

post #1 of 4
Thread Starter 



Stable:
CPU 4.125ghz
NB 3ghz
HT 2.5ghz

Voltage is at 1.5 because I was trying to get it to 4.25ghz but couldn't get it to stabilize no matter how I messed with the multiplier and bus. ANy suggestions on how to get more power out of this bad boy?

Also, ram is set to stock. Corsair XM3-1333 ... suggestions on how I should tweak the ram timing?

Hyper 212+ is my cooler.

* Nice clocks! - but the HT doesn't need to be that high. If it doesn't decrease your performance and remains stable enjoy it. It's been shown in the past that much over 2200 will decrease performance to an extent. You'd have to do your own testing. Try using Vantage as a test because (the HT Link) it feeds the PCI lanes and will affect your GPU performance.

* For RAM timing, at 1333 the best timings you can hope for are 5-5-5-15. Some kits are possibly capable, many are not. Go easy on the voltage or leave it at stock. Small bumps will help in some sense but usually more so for frequency increases than lowering timing (depending on what Corsair allows for clocking; ie - my kit is warrantied up to 1.9v - check for yours). Change one at a time and test - test with SuperPi 32M.

* Only thing left would be to find the lowest stable voltage possible for your CPU and CPU/NB. 1.4v is about top end for the CPU/NB - some push harder under water.

How are your temps? Also have you checked to see if you have any VDroop going on, and if so are your utilizing LLC to maintain the voltage when testing for stability?

ty!

I wasn't sure about the HT Link, I had it at 2ghz and actually upped it when I went from 4ghz to 4.125ghz.

TY For the ram help!

Yeah, I need to drop the voltage, I had it stable at 1.46 earlier.

56C after 6 hours of prime95 was what it topped at; 90% of the time it was at 52-53C.
No I have not checked for VDroop.
