Are you running those ultra kaze's all-out? I can barely stand my various 2000 RPM fans at full speed, I don't think I could deal with 3000 RPM.

I like my Venomous X/Scythe Ultra Kaze 3000rpm combo. With my i7 920 @ 4.2Ghz and 1.4 vcore, my temp maxes out at 70c during the OCCT Linpack test, which is suppose to generate maximum heat.

Im getting 38c on Idle and 52c under FSX load. Prime95 pushes my temps to 66c.Again, this is with an Corsair H50.

Prime 95 is single-threaded. Unless you were running a custom implementation such as Orthos, you aren't really stressing your CPU. Try running Linpack and watch your temps hit the 90's.

Yep, with FSX turned up and flying on VATSIM with a headset, you can't hear the computer, plus I only use it for FSX. I have a laptop for general computer use.

Yeah, my idle temps are around 40-42, and load is in the 55-60 range, but that is with 1.4 vcore and 4.2Ghz. Try OCCT Linpack, I guarantee that your load temps will be higher as it is designed to push the heat. With Prime95, my load temps were much lower than with OCCT Linpack. If you can pass 1 to 2 hours of OCCT Linpack, your overclock should be 24/7 stable, unless of course you have other hardware issues.

Ah, that makes sense then. I don't generally use a headset for sound so ambient noise stands out a lot more.

Here are my settings in case you wanted to try.Cpu Ratio = 21xBclk Freq = 215cpu volt = 1.35cpu pll = 1.81QPI/Dram = 1.35IOH volt = 1.16ICH volt = 1.12cpu differential amp = 800mV

What settings do you figure I can mess around with to get my clock higher on lower volts?I hit a bclk wall at around 178 I think. Kinda bad how poorly inconsistent these $1000 chips are, aye?

Say Again? Ok, it's a single threaded app afaik, but it will detect the number of cpus; and when running the stress test, it will spawn a worker thread for each cpu. I found prime95 useful to detect instability within a few minutes, then move on to another app I found sensitive to oc to verify. It's also useful if the thought of those 90

@HyperionXLHi there,As you have the same Mobo as mine you should first download and install BIOS F7e (it is important to always use the newest bios for gulftown)This bios is beta but it runs flawlessly on many X58A-UD7 already.http://forums.tweaktown.com/f69/gigabyte-latest-bios-28441/Update Procedure: 1. Load optimized bios settings. 2. Put the downloaded bios on a FAT32 formated USB stick and plug it in 3. go into bios and hit F8, search for the bios on your USB drive and let this install. 4. hit ESC to reset and reboot. 5. Into bios load optimized bios settings.Now pull out 3 of your six memory sticks. Reason: with 12GB of memory you need more QPI/VTT, so start with "only" 6GB to see how far your CPU can go. Don't use more than 1.4 VCore and 1.4 VTT/QPI for 24/7! Keep in mind, that also to much Volt will cause instability and the combination of VCore, VTT and VDIMM is the key.Use Prime95 for stability Test at least for 1.5hhttp://forums.tweaktown.com/f69/latest-ove...ty-tools-30530/Use this Settings for Prime. Threads are automaticaly set (6 or 12, HT off or on)You can use RealTemp for measure CPU temp. Use RealTempGT.exe to see all six cores. If you have Everest this will do the job also and you can see temp of your northbridge which is also important to know. If you have some question. I have a bit more time now.Cheers!

Almost forgot. You have to leave the sticks in the white slots and pull out the sticks in the blue ones.

Thanks Crash...Found the F6 on Gigabytes website and figured that was the latest bios. Twas wrong I was.I'll pull the sticks out again and see what happens (although it didn't make much of a difference in my last round)Thanks

Took the sticks out, disabled HT even though I don't really want to do that...Able to drop the vcore down to 1.45v.... I really got screwed on my chip.

Can you post your bios settings and temps?

They're all stock except bumped vcore, bumped vtt and memory v at 1.66Other than that I leave memory at 2:10 ratio and just trying to flip around multis with blcksSo far very unsuccessful with low voltages.With 1.5v, I was seeing temps at 80C max with LinPack and about 70ish with Prime95.Just think I gotta sell this one and get a new chip.

Don't give up!What do you mean with stock? Auto or standard values? You have also rise your ICH Voltages to gain stability. You have to try out many combinations and that will need some hour's. I need CPU ratio, Uncore and QPI clock, Memory clock, BCLK clock and Voltages for CPU, VTT, VDIM and ICH to help you.Can you try out this settings please? Use Load Line Calibration Level2 that is important!

Thanks for the tips, again. I've tried several different voltage settings and tried the above, as well. Just won't stabalize above 4.0 without a voltage over intel's max from the whitesheet.I've spent about 20+ hours toying with this, so I'm pretty positive I just got the worst chip out of the batch. I'll go see if I can exchange it, but probably can't. Just gonna sell it and buy a new one. Putting my simming on hold until then, unfortunately.Edit: Scratch that. I managed to get it stable at 1.45v at a 4.389 overclock. LLC is enabled so temps crawl high with LinPack, but shouldn't go too high under normal usage. Still a bad chip and I'll be looking for a replacement soon. I want a cherry chip next time!
