Intel 45nm OC Result Thread (Wolfdale E8400/E8500/E3110)

[larciel]

Due to overwhelming thread about incredible oc results of E8400, I thought it'd be best to make a thread to share the results only, so people can see what to expect from certain mobo/cpu batch/hsf combination.

Please limit to results only and share opinions in other threads. and state whether spec is prime95/orthos stable or not.

Stability Testing Program95 dual orthos
Stability Testing Time: 4.2ghz cpu stress 10hrs 65C (wont pass ram stress test)

Programs are really screwy with the new 45nm tech. Coretemp reports crazy temps. sometimes at 4ghz im 72c load, sometimes at 4.2 im 63c load. same stress test in orthos. sometimes coretemp says my VID is .09375 sometimes it says 1.0875. And on top of all this none of the newer beta bioses, including my abit ip35e bios 15 are even close to stable. They are so wacky never does the same thing twice. i booted at 4140mhz with a 1.2 vcore. WTF is going on LOL we need better software, drivers, bioses & updates - it will probably be another 3-6 months before anyone can make some definite conclusions on these chips overclockability. for now it looks good. 1.2 volts load on ~4.1+ ghz with sub 65C load temps on air is great news, but everything else that goes along with it is screwed up.



Edit: i need some pc2 8500 ram. im FSB limited by my 800mhz ram. Anyone wanna trade ?? I can run dual orthos blend/large fft overnight at 4050mhz with 1.34v actual. temps hit 68-70C *probably need better case airflow* I think i'll be able to prime at 4400-4500mhz with new ram & stay under 80C with a little Vcore tinkering-and at least boot at 8x520 to see if I can go over the 500mhz FSB.

I picked one of the new shipments from MicroCenter during my lunch break today. I'm at work right now, but I'll post some information now and update this post after I do some testing.

Update 1: I took my X6800 CPU out and replaced it with the E8400. I have the CPU voltage set to Auto in the BIOS, but the 780i is showing 1.30V as the current voltage. I also have the CPU set to 3750MHz (7.5 x 500) as a start for overclocking. The board may automatically set the voltage higher for overclocking, but I'm not sure. That's how my previous 680i board worked anyway. One important thing I noticed right away was the ability to set the FSB to 500MHz with no problems. My X6800 wouldn't even post when using a 500MHz FSB on this same eVGA 780i. These Wolfdale CPUs are very FSB friendly it seems. Will post again later after some more testing.

Update 2: I'm at 4GHz (8 x 500) right now with the voltage still at 1.3V. I have two instances of Prime95 running. I wish I knew what the temps were. The new (and uselessly bloated) nVidia Sytem Monitor tool is telling me my temps are 46/43 at load and 51/50 when idle. More testing to come.

Update 3: I had some problems with the eVGA 780i board. At times the board would fail Prime95 even at default clock speed and voltage. I took the 780i out and put the eVGA 680i back in after flashing to BIOS 1.32. The 680i doesn't have any problems with the E8400 and appears to work great.

I went back to MicroCenter and returned the 780i. I also purchased 4GB (2x2GB) of Corsair TwinX PC6400 DHX for $149. The memory is rated at 800MHz 5-5-5-18 @ 1.8V.

I wanted to see how low I could get the voltages with 3600MHz @ 9 x 400MHz. I have the eVGA 680i set to 1.20V CPU (1.15V at load) and the rest of the voltage settings set to their lowest possible in BIOS. The memory is running at 500MHz (1000 DDR) @ 1.80V 5-4-4-15. All of the fans in my Antec 900 are set to low and the nForce fan is set to 50%. Everything is still running really cool and quiet. The max temperatures I've seen Core 1 and Core 2 go to is 52 degrees C with dual Prime95.

Update 4 (Final): I found the settings I'm going to use for 24/7 use. The CPU is at 4050MHz @ 1.3V, the 680i is at 450MHz FSB, and the new Corsair memory is at 525MHz (1050 DDR) 5-4-4-12 with 2.0V. It's been running dual Prime95 for the past 24 hours. On top of that I looped the 3DMark06 demo for 8 hours during the night. It's very fast and very stable.

Looking forward to this one. I'm going to be buying mine soon.

I've noticed a lot of disagreements about what constitutes stable so I recommend the following be added to each post so people can judge for themselves.
~~~~~~~~~~~~~~~~~
Stability Testing Program: (e.g. Prime95)
Stability Testing Time: (e.g. 8 hours)

 

[AdamK47]

What's the best program to monitor temps on this Wolfdale with Vista 64-bit?

 

[krnmastersgt]

I want a .45 nm chip That'd be very very nice indeed

 

[taltamir]

since a single nm fits 100 hydrogen atoms in a row... 0.45 would be the size of 45 hydrogen atoms... and the metal atoms used in chip construction are bigger then hydrogen...

Well I got my E8400 today and put it in. Kind of worried about my temps so far, but the readings are a bit odd too.

Temps running P95 read 56/57 in Coretemp at 3.6ghz. Does this seem a bit high? Speedfan reads 48/55 oddly enough. And that is with my fan at 1k rpm. If I up it to 2k RPM, the temps don't drop at all. And my V-core is set to 1.225 in biso and CPU-Z shows 1.168v under load. Isn't that a bit much vdroop? Any info would help as I haven't O/C a processor in a very long time.

Oh and when I stop P95 CoreTemp reads 46/42 and speedfan reads 47/38, wtf?

Update:
Upped it to 430x9 = 3870mhz
Had to up the voltage on my memory to 1.9v to get it to post. Upped my Vcore to 1.3 in bios, shows as 1.232v under load in CPU-Z. Temps in CoreTemp show 62/64. I'm pretty concerned about temps now when going up to 4.0. Room temp is 18C if anyone wondered, so its not my room temps.

Update 2:
Upped it again to 450x9 = 4050mhz
Left the voltage the same, 1.3v. Booted up just fine and ran p95. temps stayed the same as before but it errored at 3 minutes.
Upped vcore to 1.32v in bios, 1.28 idle, 1.249 load. temps went up to 65/67 but so far stable running prime. This is my goal so getting to 4.05 at 1.28v is awesome with me, but i'd rather have lower temps. Maybe lap the HS?

Booted the chip up at my E2140's old settings, which was 363x8 for 2.9Ghz at default voltage. My BIOS claims that default voltage is 1.08v, Core Temp says my VID is 1.1125V, and CPU-Z said my voltage was 1.18V, which sometimes dipped to 1.16-1.17 under load.

Got the chip up to 3.42Ghz 380x9 at these voltage settings with a small amount of priming. Tried 401x9 next, and Windows crashed upon booting. Raised my voltage to 1.22V in BIOS, which reads 1.18V under load, which loads Windows and allows Orthos to run 3-5 minutes before Core 0 errors out.

Ambient temps at the moment are between 75-77F, and I'm idling/loading at 30/42C, or 45/57C, depending on whether you like to use Speedfan or Core Temp to read your temps. I've also noticed that the corners of my IHS are terribly, visibly not flat with the center. The good news is that the center of the IHS is making good contact with my HSF, unlike my E2140 which used to have 3-5C difference in temps between the two cores.

That's enough babbling from me...just check my cliffs below, I'll update each successive bump I can muster there.

Cliffs
3.42Ghz @ 380x9 @ default (1.18v?) - 45/57C idle/load
3.60Ghz @ 401x9 @ 1.20V CPU-Z - 46/58C idle/load
3.70Ghz @ 411x9 @ 1.23V CPU-Z - 47/60C idle/load
3.80Ghz @ 422x9 @ 1.27V CPU-Z - 48/63C idle/load
3.90Ghz @ 433x9 @ 1.32V CPU-Z - 49/67C idle/load

Well so far

Larciel 445 1.36v
Jaredpace 460 1.38v
AdamK47 450 1.3v
Riverhound777 450 1.32v
Covert24 412+ 1.09v
Avalon 433+ 1.31v

All with the 9x multi

Somebody with good ram needs to drop the multi and give us a max FSB report.
Show us some 500+ FSB

*edit*

I see Larciel posted 500x8 stable with pc8500 ram. Would be nice to see how far it would go at the 7x hint,hint

And check out Covert24 ovaclk'n and undavoltin, you go boy

 

[Tempered81]

Ive seen 612FSB on air with an 8200 & 8400 retail on a DFI lanparty 35 UT

 

[GuitarDaddy]

Nice, we can only hope the quad 45's will play so nice with high FSB

 

[Tempered81]

I havent seen a quad over 512-520ish. from the same guys at XS who oc these things on air/ln2/dice/water/liq/vapor/cascade/phase yada yada yada. I suspect if they can do 620 on dualcore & 520 on quad core, that I will be able to do 510ish on a dual & 410ish on a quad

 

[Riverhound777]

I'm still worried there is something wrong with many of these chips. I've been reading a lot of post on various forums with people having very high idle and load temps, even at stock settings.

I don't think it is Bios readings since some peoples read just fine while others have chips that have stuck temps and then others like me with high temps. I wonder if there is something wrong with the IHS contact point not transferring the heat correctly. I mean running at 1.296v and getting 45C idle temps? Obviously something isn't right.

I also find it very odd that resetting my CPU, lapping my heatsink, and turning up my fan to high all have no effect on my temps.

mine is at the exact same speed & volts and idles about 45. but on full load dual orthos it gets to like 65.. only when vcore at 1.38 & 4200mhz does it goto 71-72C on load.

I'm pretty happy with my temps. I idle at around 40C and my load temps are 60C to 62C with dual Prime95. I can live with that.

It was good at 4.05 Ghz for 16hrs 15min @ 1.320 V before my 2nd core craped out in Prime 95, I bumped the voltage 1 notch in the bios to 1.35 (now 1.328 load) w/ Voltage Damper enabled and am testing again core 0 reads 56-58C and core 1 is 53-57C the 2nd core is cooler but is the one thats crashing /sigh.

edit: I haven't tweaked the memory yet its just stock working on the CPU atm.

Edit: welp its stable for 49hrs w/ Prime 95 + runing some Civ 4 w/ 1.328V Gonna have to tweak the memory next but finaly got the CPU stable.

Exactly, that isn't good. Some people are running the same speed on higher voltage and getting lower temps. ~55C load on air. Which is still high if you ask me.

Spent hours figuring out how to overclock my rig, finally setup some good settings.

Vcore - 1.375V (from BIOS) CPU-Z and windows temp applications are reading this vcore as 1.26V (off by .10) think this could be a asus board issue or a e8400 voltage sensor issue

reinstalled heatsink properly and my core temperatures are reading at 43-45C idle and 60C max load and not more. CPU TEMP reads as 22C idle and 50ish load
Prime ran fine, didn't finish the test but ran it for an hour, tested other applications and benches, system was stable.
I think i can push it further now that i solved my heatsink issue, but my benches and temps are corresponding with the benches and reviews of this chip which means im on the right track. Further testing to be done later.

my question is, when looking at temperatures, what is the max limit for CORE TEMPS and CPU temps, as these are two different temp readings. My guess is the core is at the heart of the cpu chip and the cpu temp is the temp at the base of the cpu chip case (metal thing). What are the benches temps reporting, the core voltage or the cpu voltage?

[Team42]

With all the problems being reported concerning voltages and temperatures, especially given the disparate nature of the reports being given by what have, up to now, been considered to be otherwise "reliable" software tools, I am surprised that so many people are "happy" with their temps.

Does anyone really know how the 45nm cores react to overvolting? Perhaps the "reliable" temp monitors aren't accurate. What works for Conroe might not work for Wolfdale.

From what I've seen, you could trust CoreTemp, SpeedFan et al with a 45nm cpu as much you could a politician with your pension.....

I may be wrong, but if I am, why are so many people having probs with temp monitoring? Discuss...
