My new Ivy Bridge chip came in the mail yesterday and I've been playing with with it. swapped it out for the Q6600 + X38 I've been using for 4 years, but kept my watercooling loop - Swiftech Apogee + Black Ice GT triple rad + Laing DDC pump + PC Ice coolant. Pulled the loop apart (haven't touched it in 4 years) and gave everything a thorough scrub, but surprisingly it was pretty clean inside. Used Phobya HeGrease - reviews placed it among the top thermal compounds and it was cheap. Don't mind the dust! Currently my settings are: Voltage mode set to offset, -0.025mv C3 state: Disabled C6 state: Disabled C package state: Disabled Internal PLL overvoltage: Disabled LLC: Level 5 As seems to be the case with most Ivy owners, I'm slightly concerned with temps. These are my results: 4.3ghz -> 114.5gflops Linpack +0mv -> 1.240v As reported by CPU-Z under load Peak Temps: 90c 4.4ghz -> 116.5gflops +27mv -> 1.272v 95c 4.5ghz -> 120gflops +35mv -> 1.280v 100c 4.6ghz -> 122.5 +58mv -> 1.320v 105c - Throttles Effectively I'm unable to exceed 4.5ghz with watercooling because of temperatures. The block doesn't even get warm to the touch, and my TIM application is good - I tried reapplying with no net gain. Also, Linpack + Prime seem to be quite insufficient for stability testing. I left Linpack running overnight at 4.5ghz/1.262v and it was running when I woke up, and Prime doesn't crash either, but I get force-closes and crashes in games within 5 minutes unless I add another 0.010v. So here's my question: Do you think lapping the CPU and waterblock might improve temps or is my limiting factor almost certainly between the IHS and core? I don't plan to de-lid my CPU. EDIT: Also is there a way to reduce ram set aside for the IGP below 32MB? I can't seem to find a way to disable it entirely in BIOS.
