P5KE-Wifi + Wolfdale = Incredible!!

Logan... You also tend to burn the lips... DON'T KISS THE CPU WHEN IT'S RUNNING!

If it isn't running, it is ok to kiss your cpu as documented at the following website, just make sure you coat your lips first with a good thermal paste.

Look at this OC on air this is unreal...

This is just too good.. I am going to get this system Water cooled too...

I just noticed the 1.6V (?!?!) going through that. Are you serious?! I mean, i saw 1.49V when you were at ~4.5Ghz, and was astounded, but 1.6V, ain't that a little too high or can these things really hold that much with decent cooling?

[ccperf721p]

It's too early to tell on the 45nm parts just how much voltage they will take, that being said I haven't seen and Core2 CPU's die from 1.8 or less with good cooling in place.

If you can afford to replace the CPU, by all means push it for everything it has.. I have hit C2D's with 1.75v and it still lives a happy life in someone else's rig

Well, my P5K-E arrived today. After a few hours of head-scratching regarding the LAN (Not being detected, had to use dad's comp to update router's allowed MAC addresses). I've not run any benchies yet, but already, i can feel this board has something about it. WITHOUT any extra vcore, i managed 3.5Ghz without a problem. Got some Dominater memory running, simply because i like Corsair .

Gonna try giving it 1.4v later, see if i can hit 3.8 or even 4.0. 4.0 has been a challenge for me for a long time. 3.0 was what i always wanted to hit, but when it's already that at stock, it's not so amazing .

UPDATE: Very simple; 1.5V, 444Mhz FSB, startup, bam! 219K AM3 Score and 11.734S SuperPi to 1m. Yet to run 3DMarks so will report back soon. CPU-Z: CPU-Z Validator 2.1. 54C Core #0 and #1 Temps though, perhaps i've got one with a "stuck" temp sensor? It's only reported at this temp in CoreTemp, whereas RealTemp 2.41 reports it as 44-46.

Update: 38309 3DM03, Up from 37184
Update #2: 22038 3DM05, Up from 18405
Update #3: 12350 3DM06, Up from 11465

If I was run at 1.75 I'd be happy in someone else rig to! LOL

WellI have brutalized this E8400 Processor for 4 months now.
It now runs smoothly 24/7 at 4500 mhz running 1.512v-core
It is still air=cooled only. With my Air-cooler it does not matter what I run, it has never seen higher than 52C on either core at this voltage setting or this high speed.
However when I slow it down I can get it to run 400o mhz easy on 1.247 V-core. Sorry for me that just won't do. I have the need for speed and this board and processor gives it to me.

My P5E with it's E8400 even gives me more!! The X38 chipset will clock for clock give the P35 a pretty good spanking. On my P5E I am running
4 x 1gig of G.Skill HZ set on the 5:6 divider with the timings set at 5-5-5-6. Pretty sweet at 500 fsb and DDR1200 with 4 sticks!

Both of these boards are just flat out dependable and strong!

You cannot go wrong with either. The 2 E8400's I have just keep on going and return mind boggling performance.

Well, after disabling load-line calibration, temps have dropped to 53C in Coretemp, 43C in Real Temp and 36C in AISuite. I'm tempted to go with AISuite or RealTemp as Coretemp just doensn't seem to ever be right, 53C at idle with this cooler can not be right, there's just no way it's possible. So i'm avoiding using that. I'm running at 1.5V in BIOS, yet AISuite, CPU-Z and i think BIOS reports were all saying 1.4V. I think i am going to push ahead and try 4.5Ghz sometime today. It's 4am so time for sleep i think.

[weldzilla]

Yeah Skool just use real temp. That is the one to go with when running these Wolfies. I see in your sig that you are running 1.5V @ 4ghz.
You should have no probs with that. What does cpuz shopw as your actual voltage?

CPU-Z shows as 1.400 V which indicates to me that either there's a whole 0.1 Vdroop or i've read the value wrong that i put in BIOS and it is actualy 1.4V. I'm sure i put in 1.5V, but even if there is a 0.1 VDroop, that limits me to 1.6V CPU-Z reported voltage. When i go to 1.625 or above, the values are in red and i always get a CPU Voltage warning when booting. Any way of disabling that?

I do have to say that Wolfdale as a whole is similar to the way that the A64's "replaced" the early P4's simply because they were that much greater.

All these boards have some crazy v-droop. There are some easy mods to fix them. You can google and find the fix. Mine was as easy ans a number 2 pencil and a SM resistor.

I was wondering why there was a whole 0.1V Droop . Just read a bit more while looking for the specific vdroop mod for this board and a recent thread on another forum (14th april 08) indicates that the latest BIOS fixes the VDroop problems for this board as long as load-line calibration is enabled. Gotta be worth a try.

UPDATE: BIOS 1013 seems to have fixed it and now showing as 1.488V (0.12 VDroop). It's enough to make me happy.

While I sit here waiting for a bios update for my Maximus Formula, a P5E-VM HDMI happened to end up on my test bench. I have heard nothing but good things about the capabilities of this board so I was dying to try one out, considering I maxed out the capabilities of the Formula while still on relatively cheap air cooling with a Q9450. I will be playing with it throughout the week and will put up some results. I have yet to find a board that will even justify water cooling a 45nm quad, much less strapping my single stage to it. Who knows, maybe this g35 based Micro atx board will allow a little more.

[Samuknow]

Look forward to seeing the results..

They do some serious clocking, much fun to see..

[Samuknow]

Have you fired up your phase unit yet?

I look forward to seeing what you can do with that chip when it is chilly.

[ccperf721p]

Haven't had a board that will do enough FSB with a Quad to even warrant hooking up the phase. Best I have managed is 465 FSB, this new Q9450 I picked up will do the 465 at 1.28v so, I'm just waiting impatiently for something that will do the trick.

[dsio]

What board was the 465 on?

My P5K, the formula gives up at 450.

I currently think I'm still limited by my DDR2-800, but i'd be keen to see how far it will go with some DDR2-1200.
