Orthos just failed, blue screened. I've now upped the CPU PLL to 1.9V... (voltage details in previois posts). The system is still blue screening within 30mins prime 95... any ideas lads ?
dunno if people are still posting OCs but here goes: Motherboard: Asus P6TD Deluxe CPU: 920 D0 Cooling used: Titan Fenrir Overclocked speed: 3.8 / 4.0 / 4.2Ghz Baseclock (bclck): 190 / 200 / 200 Multiplier: 20 / 20 / 21 DRam speed: 1600 7-7-7-20 1T Turbo Mode (on/off): off Hyper-threading (on/off): on HPET (on/off): Off Speedstep: Off Loadline Calibration/VDroop (on/off): on CPU Voltage: 1.275 / 1.296 / 1.328 CPU PLL Voltage: 1.90 QPI/DRam Voltage: Auto DRam Voltage: 1.64 Idle 40ish for all 3 overclocks, under load the its 65 / 75 / 85. Might try lapping the cpu and cooler!!! Need to do a proper burn in and see if these OC are truely stable, so far its been 10 mins of prime and a few rounds of MW2!
speedstep enabled turbo off BCLK: 200 DRAM: 1603Mhz CPU voltage: 1.31250 CPU PLL: 1.90 QPI/DRAM Core voltage: 1.3 DRAM bus voltage 1.64 LLC disabled. drewbear - its weird how you arent able to up the QPI/DRAM, that seems to be the cause of the problem
Yeah, the system absolutely will not boot unless the QPI/RAM is set to Auto..... I do have another setting in the bios called QPI PLL currently set to auto which is believe is 1.1V Would you recommend me increasing this to see if it helps ? Thing is, the system fails within 10 mins of prim95, However it now runs 3d mark vantage fine and i can play all of my games... i suppose it just depends what is classed as stable
Yeah, the problem is that if i increas this voltage even one notch the system will not boot. Looking at your sig, i have the same ram as you, running at the same speed, so i am going to have to find out why the system wont boot with increased qpi voltage. Motherboard is EX58 - UD3R btw. Gonna have a look on the gigabyte forums in the morning, see if anyone else is having issues Just my luck
I've just finished the first session of overclocking my latest second hand acquisition: an i7 920 D0 from the 3845B "Golden" batch. It's running at 4.3 Ghz at 1.35v Vcore which is good but I'm not sure that it's "Golden." There might be more to come yet. Anybody interested in an i7 920 C0 that'll do 4.1 Ghz at 1.38v Vcore?
Motherboard: Asus P6T deluxe CPU: i7 930 Cooling used: Titan Fenrir can someone please help me with the BIOS settings?
Build finally together, here's what I'm looking at daily use... Motherboard: EVGA Classified E760A1 CPU: Intel Core i7 920 D0 - Batch 3910A301 Cooling used: Corsair H50 - Push / Pull with Scythe S-Flex E 120mm Fans Overclocked speed: 3.8GHz Baseclock (bclck): 190MHz DRam speed: 758MHz (1516MHz Effective) - Will be tweaking to get better timings... Turbo Mode (on/off): Off Hyper-threading (on/off): On HPET (on/off): On Loadline Calibration/VDroop (on/off): On CPU Voltage: 1.23750 CPU PLL Voltage: 1.22500 QPI/DRam Voltage: 1.12500 DRam Voltage: 1.65000 22 Hours of Prime95 Small FFT's later...
For daily use... I pay my own electric bill here, so I'm TRYING to keep it a bit more power efficient. No promises for benchmarking though. I literally just got the build finished a few days ago. There will be more to come.
im only teasing i run mine at 4ghz but its mostly at 2.4ghz idling on speedstep. if you are getting a stable 3.8 at such a low vcore you should be able to get 4.2ghz i reckon. how comes ur PLL voltage is so low?
Well it remains to be seen... From what I got from some results on my batch number on X-S, my chip should actually run hotter and require more volts than the 38XX batch chips. Everything varies though. Which PLL voltage? I don't want to increase any voltages higher than needed for stability...
i think its EVGA and ASUS naming things differently. If you scroll up youll see my settings - the CPU PLL is 1.9v
If you look at the screenshot I posted there's QPI PLL and CPU PLL (along with IOH PLL, but who actually changes that ). That's why I asked. As for why it's so 'low'... I don't need to raise it to keep stability. Not yet anyway. I may bump it up a notch if it needs it, but it passed 24 hours of Prime small FFT's without a bump.
Wow guys, this thread gives me hope... lol... Does anyone have settings for a Rampage 3 Gene motherboard. I'm using air cooling (Thermaltake V1). Any suggestions for a stable 3.8GHz over clock with Stock RAM? Motherboard: Rampage 3 Gene CPU: Core i7-920 Cooling used: Termaltake V1
Sorry to bump an old thread, but I'm pulling my hair out trying to overclock my 920 D0. Could someone with a decent overclock using a Gigabyte UD3R please share their setting or even just give me some pointers? Any help would be greatly appreciated.
Use CPU z to find the max voltage at stock speed ( run prime 95 to load the CPU) Set multi to 21/22 depending Boot 2.4/2.6 ghz ish been a while Increase the blk clock till you hit 2.8 ghz set voltage to what stock required If it boots run prime test stability No blue screen continue till you get one 2.9 ghz 3ghz ect Once you hit a blue screen Increase the voltage by 0.05 per reboot till its booted and stable Then check load temps below 80 is fine Back to part 1 increase blk again till you crash and blue screen Then repeat the above till you hit your required overclock 3.6-4ghz. Takes time and patience not just banging the blk to 200 and expecting miricles
