Hi everybody! Is anyone interested in devoting a thread to their i7 overclocks? I'd suggest something like: Motherboard: CPU: Cooling used: Overclocked speed: Baseclock (bclck): DRam speed: Turbo Mode (on/off): Hyper-threading (on/off): HPET (on/off): Loadline Calibration/VDroop (on/off): CPU Voltage: CPU PLL Voltage: QPI/DRam Voltage: DRam Voltage: Is that enough to cover the settings common to all motherboards? I'd start it off, but I'm still running stock atm
Just posting this to see if anyone bites, tbh. Motherboard: MSI X58M CPU: 920 Cooling used: Retail Overclocked speed: n/a Baseclock (bclck): 133 DRam speed: 1600 8-8-8-24 2T Turbo Mode (on/off): on Hyper-threading (on/off): on HPET (on/off): on Loadline Calibration/VDroop (on/off): on CPU Voltage: auto (1.25) CPU PLL Voltage: auto QPI/DRam Voltage: auto (1.80) DRam Voltage: auto (1.65)
Motherboard: Gigabyte GA-EX-UD5 CPU: 920 (D0) Cooling used: Swiftech GTZ Overclocked speed: 4.2 GHz Baseclock (bclck): 200 DRam speed: 1600 8-8-8-24 2T Turbo Mode (on/off): on Hyper-threading (on/off): on Loadline Calibration/VDroop (on/off): on CPU Voltage: 1.45v CPU PLL Voltage: auto QPI/Vtt Voltage: 1.515v DRam Voltage: 1.65v (Although now its summer and the computer makes my room too hot, I have backed off the OC to 3.8, which is the highest I can get with stock volts).
Motherboard: EVGA X58 SLI (E758-A1) CPU: i7 920 D0 Cooling used: Thermalright True Copper Overclocked speed: 4.2 Ghz Baseclock (bclck): 201 DRam speed: 2010 Turbo Mode (on/off): On Hyper-threading (on/off): On HPET (on/off): ??? Loadline Calibration/VDroop (on/off): Off CPU Voltage: 1.3 CPU PLL Voltage: 1.75 (default is 1.8) QPI/DRam Voltage: 1.1 DRam Voltage: 1.65 Above are the settings in the bios, below is a pic of what's reported. What is HPET? Why are you concerned about the CPU PLL and the QPI/DRAM volts? They really don't seem to affect much. You should be looking at the CPU VTT instead.
Here are my loads with LinX, of course I never run it that hard for long. In everyday use it stays in the low 60's max. Of course I do pressure test it now and again And that's all on Air
I've just had a quick Prime95 run on mine, 3 tests completed (just checking stock settings are stable, really). Testing whether the ram could run at 1T instead of 2T. With a retail Intel hsf, my temps went up to 84c max and after stopping the test have descended to 45c after a few minutes. Definately need a better hsf! Nice results, Slaymate! As I understand it, Dram and QPI voltage are linked, i.e. if Dram is set to 1.65v you have to set the QPI within .5v (1.15v in this case) - is this correct? HPET is an option in the bios called High Precision Event Timer iirc.
Ok, my HPET is turned off, I think. I'll check it later. No, your CPU VTT needs to be within .5 volts. My default cpu vtt is 1.1 volts and I've got it set to 1.25v in the bios, thou it's reporting in at 1.48v in Windows. My DRAM is set to 1.65v in the Bios but it's reporting 1.69v in Windows but it's still within .5 volts of each other. Also, 1.1v + .5v = 1.6v not 1.15v
Here's my 24/7 overclock: Motherboard: Asus P6T Deluxe CPU: i7 920 D0 (SLEBJ) Cooling used: TRUE Overclocked speed:3.8GHz Baseclock (bclck):200 DRam speed:1603 Turbo Mode (on/off): off Hyper-threading (on/off): on Speedstep (on/off): On HPET (on/off):? Loadline Calibration/VDroop (on/off): off CPU Voltage:1.27 CPU PLL Voltage:1.8 QPI/DRam Voltage:1.3 DRam Voltage:1.66 Where is HPET on the Asus's AmiBIOS? Furthermore.... does it actually DO anything? Thats running prime95.. temps will be around 2-3 degrees higher with linpack. [edit] Added Speedstep to the list. May do a suicide bench later
It wasn't too hard, but the voltages are a bit higher than I would have liked, so need to see if it's still stable at lower voltages.
I thought CPU VTT and QPI/DRAM V was the same thing? Slaymate: Is your TRUE lapped? Just interested if the copper version had a flat base or not.
My mobo has a CPU VTT voltage, QPI PLL VCore voltage and a DRAM voltage. I don't have a QPI/DRAM voltage. But I guess they could be the same with different names. My QPI PLL voltage is set to the default of 1.1v but it's not the voltage in question. Actually I have 2 - i7 920 setups, 1 has the True Copper and the other is a std. True. And they were both rounded. Thermalright makes them all that way. But they work Great after you lap them True Copper lapped std. True lapped
Mine's at stock. I'm far too lazy, even though I chose a motherboard that I knew would be a great overclocker and I have a Nocuta HE1366.
You could just raise the blck to get over 3ghz without making any changes to anything else. I have adjusted nothing but the blck to get 3.3ghz for day to day usage.
Well here's my effort. It's watercooled. Cpu-z is reporting the vcore at 1.376v but it's actually set at 1.42v in the bios. I generally use this overclock for benching only. I've never really spent long enough on it to see if I can get more. I also had to enable LLC to keep it stable. Got me a score of 2403 on the Custom PC benchmark. On a 24/7 basis, I have lowered it to run at 4,000mhz (200x20), turbo off. Needs a lot less voltage and no LLC. I am perfectly happy with these overclocks, but everytime I read a thread like this it makes me want to push that CPU to 4.5gig.
What are your temps on load? 50C idle under water seems high to me, even at 1.4v No idea what RAM you have but I reckon it would do 848 at 1T with those timings. Every little helps
That was done in the heat wave a few weeks back, was over 30deg in the room. Normally idles around the 40deg mark, hitting high 60's at load. Even on that day it only hit 70deg at full load. Yes the ram will run at 1T, see below, but for some reason I get better results withthe ram like that and a higher cpu overclock. I haven't taken the time out yet to get them both working fully together yet. Something I keep meaning too.
