My retail 45nm Wolfdales - E8200 + E8400

[OBR]

Chips are Retail, but OEM ...
FPO: 750A, 745A ...

... on default voltage is max OC on Maximus Extreme only 3300MHz for both chips ...

Maximum oc with safe voltage (max 1.45V in BIOS) real 1.38V is for both is about 3800MHz ...
E8400 is not stable at 4GHz at any voltage ... this first 45nm chips are OCers like first Conroes ... nothing special!

[godsfist]

Yep I've had 2 E8400's and both will do 4GHz but I wouldn't call it stable

And they both run much hotter than my E6750 at 3.6GHz

[Eniqmah]

ah sh*t. im nervous now.

[godsfist]

I'm going out tomorrow to see if 3rd time is a charm.. if I don't get no love the E6750 is going back in

You just need more vcore dude. Give it 1.55v and i suspect it'll have no problems at 4200 (on the 8400 that is).

[Falkentyne]

Why haven't you activated Vdroop control in the BIOS? I'm 100% sure that a maximus extreme has this setting. That should definitely get you somewhere past 3.8 ghz....

I find it very odd that neither chip would do 4 ghz, though (please activate vdroop control first). Since most qx9650's can do 4 ghz at 1.4v or below, and these are from the same process, this doesn't mean that Intel is binning the dyes for the Extreme models, does it ? .......

Later on, i'm going to check what vcore I need on my QX to do 3.8 ghz at the default fsb speed (333)...the last time I tested that, it was the 380 FSB on the 975x making the chip unstable (when 333 * 12 was stable at less vcore than 380 * 10)...

1,55V for a 45nm will kill it much faster than 65nm

Did you read his post?
He was operating at maximum SAFE Vcore. Why are you asking him to give it 1.55v on air? That's NOT a Conroe/Kentsfield 65nm he's using, you know! He's using Wolfdale/Yorkfield 45nm. (Yorkfield is the quad version, Wolf is the dual version). That can lead to a very dead, or rapidly degrading chip at those voltages without some sub zero. You DO realize that 1.55v through a 45nm chip is the same as 1.65v on a 65nm? Not many people are willing to put that vcore through these chips on air, for any thing besides a suicide run....

[AriciU]

Well. I am willing too, i'm just telling him where the problem comes from.

[Infa]

Yeah Loadline Calibration... it works well, and drops only about 0.02, and Load are stable, once you have the voltage there will be no droop at all..

just figure it out, 1.57500 on my board are 1.55, and its the same with any vcore set, and there are no droop at all, stable as a rock.. try it ..set 1.47~ in bios and you will have your 1.45, and then get back to your OC and show us!

[S1mon-]

These results are a little bit below expectations

[Leeghoofd]

OBR can we have al ook at the temps plz if you run them eg at 3.6 or 3.8Ghz ??
I just wanna see if these are really worth it , my friend wants to buy an E6850 I told him to wait till these babies popped up... my E6850 was rockstable at 3.8Ghz and benchable at 4ghz but temps were over 65°C under water with only 1.45Vcore (and IHS was as smooth and flat as a babyskin)

If these are pretty hot too I will push him towards a quad...

Currently I have an E2140 in the rig ( damn man a Vid of 1.375 ) and pretty high temps, really cheap chip ( lended to me awaiting my QX ) FSB wall at 362mhz and runs now happily at 2.667 speed but under prime temps run up to 55°C under WC...

[fireice2]

Yes, they fall quite below the ES versions that have been benched on air.

[OBR]

if i set 1.45V in BIOS, in idle i have in windows at cpu 1.43v ...butunder fully load 1.38-1.39 ... maybe is something with Loadline wrong ...

test under water tomorrow ... but on air with 1.35V real voltage is in Orthos temp about 58C degrees ...

[Falkentyne]

Wow...that definitely looks like "loadline" is NOT working....or not working properly....

I had almost that exact vdroop on my P5W before doing the mod....With the mod, my idle and load voltages are 0.02v below bios setting.

Your load and idle voltage should be virtually identical...

4 ghz may be out of reach but if it could maintain a 1.42 vcore at load, you should have at -least- 3.9 ghz.

[trans am]

Wow. Can't even hit 4ghz? were you drunk?

[godsfist]

Yeah on air I was getting around 60 degrees in Orthos on both of them

[godsfist]

You're not listening dopey, the retails are nowhere near as good as what you've been seeing from the ES

[trans am]

I know. I was just joking with OBR> Sorry your chips suck man.

[OBR]

Wow. Can't even hit 4ghz? were you drunk?

i can run every benches at 4050MHz ... but not Orthos stable

[trans am]

Do you have 45 nm quad to test?

did both max out around 3.8? Just curious since E8200 is very inexpensive.

[fireice2]

so the 4ghz 24/7 use is far from reality again, isn't it?

[jas420221]

As long as the new quads (Q9450 really) see 3.6Ghz+ on air, Im all over it.

[godsfist]

so the 4ghz 24/7 use is far from reality again, isn't it?

I hate the silicon, on one E8400 one of the cores is 10+ degrees higher than the other one.. and the other chip both cores are the same but hot as hell, like 15 degrees hotter than my E6750
