TPU's Core i7 Overclocking and Feedback

@Fitseries3

How is the performance of the Thermaltake Frio compared to Thermalright Ultra Extreme 120?

I'm currently @ 4.2GHz and max temp is 85c in Linx. Does it worth changing my True with Frio?

My True isn't lapped.

TIA
 
Thought the SR2 was only rated for 48 gb/?
 
was bored thought to try how high i can oc my rig, manage to hit 4.2ghz but only prime95 stable for 30 min one of the core would fail temp stayed around 72c, ohh well need a lil more tweaking

has anyone tried lowering bclck?? with my 1156 rig if I lower it will wont load windows at all simply bsods.
 
Hmm i have never tried. I have lowered the voltage on my 920 to .95V at stock clocks and was still stable
 
That is .95v at default clock speed right?

I doubt that would be stable at anything other than 2.66Ghz

I've done 3.4GHz with .95V. It all depends on your luck with the chip. Heck when I got my hands on a 32nm Xeon 920 equivalent I hit 4GHz at 1V

DAMN nice binge! i had mine undervolted due to heat and i had a crappy cooler on it until i did my water loop which let me get 4Ghz now im on a good air cooler now with lower temps.

I love Xeon chips. I plan on locating a E5640 for my X58 setup instead of going sandy bridge

E5640 Specs
 
Yeah a X5677 already run 3.46GHz at 1V so 4GHz wasn't really a stretch.
 
I cant wait for the 32nm 12mb cache of the E5640. Sounds like a monster of a CPU!
 
It's going to be a sweet chip. 32nm x58 chips are a sweet spot for power consumption and heat. You can air cool it to a good OC easily. Water just makes it... well, cool!
 
so can anyone give it a shot?? maybe lower bclck to 125?? thats how low I did it. I did it to try and get the memory at the speed I wanted it, and it went teribly wrong
 
I need to get a water setup again... gosh dang my 950 gets hot...

Ambient of 24C (primary problem, its 70F out right now) , cooler being used is a Noctua NH-D14. At least I got 4.5 semi-stable... but sheesh... hot!

It might seem hot, but your voltage is also fairly high. Once you go over 1.32v, these i7 chips just beg for water. It's been that way with all 15 of them I've owned.
 
that is hot for only 4 threads!
 
Paul, my 950 hits 81c at 4.2 (4/8) with only 1.26vcore and 1.27vqpi. My 920 D0 never ran this hot, even with 1.35v my 920 stayed under 80c.

Was your 920 an early batch DO? Not many of the newer chips stay as cool as early batches.

Just noticed that. It is hot for no HT.

It was a late batched 920 D0.

That is DEF hot! mine doesnt go above 69 ATM with it @ 4Ghz 1.27V

Because you are at 4GHz with only 1.27v. I'm at 4.5 with 1.35v, and lets not forget how much qpi/vtt voltages increase temps either. 1.35vcore, 1.33vqpi, for 4.5GHz. I didn't have much time to reseat the cooler, but I plan to do that soon. I'm also going to lap the 950, 5-6c difference between cores 1 and 4.

Can you give me all your voltages johnny?
 
Thanks, trying to get my I7 920 to 4.5ghz and need to voltage to reference
 
Sorry for not getting back to you yesterday, but here are my voltages on my Rampage III Formula.

4.2GHz 4/8 - 100% stable (this is my 24/7)
CPU Vcore: 1.264
QPI/VTT: 1.284
Load Line Calibration: Auto
All other voltages default

4.5GHz 4/4 - Stable enough for benching, haven't done all out stability testing yet, gets too hot.
CPU Vcore: 1.352
QPI/VTT: 1.332
IOH: 1.15
Load Line Calibration: Auto

All other voltages default

I know, seems odd that I only had to play with two-three voltage sets, but thats what makes the Rampage III Formula such an amazing board for $299. No board I've played with on the x58 chip was as easy as this one, and I've played with plenty. Not even the Classified 3 was as good as the Rampage III Formula (IMO of course), the BIOS on the Classified 3 is horrid in comparison.

I'm off to work right now, I will dump out my entire BIOS and pmsg it to ya later tonight in case you want to see every setting.
 
This is what I have mine running 24/7. I have HT off since most say there is no need to have it on. Ambient temp is 20C I would like to clock higher but I am new to Intel overclocking. I have been looking for tips that can assist me. I would like 4.2 but if HT at 4.0 would be better then I will make that my goal.
