I'm running the same (but watercooled) as my encoding server. It's great. I haven't tested the limits yet though since my ddr2 800 ram is holding me back.

Unless you're looking to squeeze every last clock out of your processor, 8 phase power is plenty good. Asus still advertises 8 phase power in many of its boards. Honestly, if you're looking for extreme overclocks, you wouldn't be looking at a mid range board. I'm not saying you won't get...

8 phase will probably not hurt your overclocks much. Asus still advertises 8 phase power in some of its boards. 16 MIGHT be better, but I doubt you'll notice a difference. You're more likely to be affected by a good/bad batch of your board than the 2x power phase. I'd guess you might squeeze...

I'd have to suggest not to buy. Seagate customer service is HORRIBLE. I bought 4 400GB drives from them about a year ago for $100 a piece. I was tricked by the 5 year warrenty. I've now spent about 8 hours on the phone to their support in India talking with people that get lost in their...

Ordered mine week before last, popped it in last weekend and booted right up at 3.2Ghz. Had to raise the volts on my chipset, but I'm stable at 3.2 with just 1.2volts vcore right now. I managed to post at 3.9Ghz, but my poor p965 based P5b Deluxe can't handle the required FSB. Looks like I'll...

Actually, doing other activities durring Prime makes your cpu work LESS, yes, that's right. It's because Prime95 will use 100% of each core it's running on, while other applications end up using extra cycles that may not be as intense as the cycles Prime95 runs. Don't believe me? Try turning...

No, just, no. You did yourself a favor though, there's a great selection of heatsinks out there which will keep your cpu significantly cooler, while running much quieter and with far superior mounting options than the stock Intel heatsink. Here's a few good options over a nice price range...

"get a real motherboard" I'm currently using that board on one of my machines, and it has no trouble with modest overclocks at all. It's based on the p35 chipset, and is a very good match for that processor. If you want to get significantly higher speeds out of that processor, you'll need to...

Yikes guys. Ok, when I said "XP can't handle 4GB of RAM" I meant, it cannot address a whole 4GB of RAM. Also, I'm quite certain that "poweraid" was not referring to MB of cache per die considering he said he "was gonna get 4 gb ram, but 2GB per die isnt very appealing to me..." Perhaps he...

This isn't even how it works, cores don't get RAM, applications get RAM. Each executable should be able to use both cores (although, for now, many will only use one) regardless, RAM is something completely separate from cpu. Each process will use the RAM it needs, just like in single core...

You should have no problem overclocking to around 3Ghz without producing any more heat than a P4 used to. If you have any interest in keeping your computer quiet, you will want to get a third party heatsink (if it's not included with your SSF case). Choose carefully so that the airflow from...

Voltages of 1.5v and up are probably dangerous for this chip. I posted some wicked overclocks earlier using as high, but never more than 1.6v I now experience some cold boot issues with my chip. I would recommend 1.45 as an absolute maximum daily voltage, but 1.4 might be more safe. I am...

You mention that your vcore is lower than stock (1.3v) however, CPU-z is known to report incorrect voltages for the E6420, can you show your voltage with speedfan or everest?

I highly recommend the P5b deluxe, 3 400Gb drives in raid 5, and an 80 to 120Gb disk for the OS. E6420 OC'd to 3.2Ghz grab yourself a couple gigs of ram, and you've got one speedy machine for cheap (This is a slightly scaled down version of my encoding monster, expect something like 30fps for...

Congrats Evoic, I know how long you've been working on that elusive 3.5Ghz I'm sorry to everyone that I haven't posted overclock information yet. I ran into issues at work an had to spend a lot of time in the office that I didn't expect to need to put in, I'm currently on vacation until this...

I would suggest upgrading to a $20-$30 cooler just for the fact that it will be much quieter and easier to install.

Please try to stay on topic! A processor is considered stable enough for this thread if it passes 4 hour orthos. End of story. Stop bickering please so we can get back to the subject at hand. I will be adding all the posts so far either late tonight or tomorrow (whenever I finish my final...

Go dnottis, go! 3700Ghz+ here we come!

Very nice overclock! Now SOMEONE hit 3.7 already!

Alright, we're sticking to 4 hours orthos. Sorry, but here at [H] it seems to be the standard cpu test. I'd love to compile something more complex, but the idea of this first page thing is to keep a record of attained cpu speeds that are reasonably stable.

Wow, over 3 days of downtime for the forums and it's still really slow... Anyhow, I will be starting a list of everyone's fastest stable overclock (4 hours orthos please) on their E6420 in the first post on this thread. I will need your speed, voltage, processor code, motherboard and bios...

Wow! What is your 1M superpi mod time!? Have you made a 4Ghz run in windows?!

To be fair, the chip has only been out for a month or so. It's not the fastest, or cheapest, so it's not really pulling bargain enthusiasts or the high end money is no option enthusiasts. I guess what I'm saying is, it's a great chip (although frustrating for some as we've seen) but it...

Hey buddy, grats on the OC. Like I'd mentioned in the E6420 thread, I'll probably make one more run after a vdrop mod and after I lap my cpu. For now, I concede. Enjoy the #1 spot, you earned it! And on air too... Grr.

Uh oh, what's the wife gonna say?

Actually, I just used my fsb x multi since fsb can fluctuate +/- .1 or .2 Mhz so 457x8 = 3656Mhz

My personal best that was stable enough to make a 1M SuperPi Mod was 3840Mhz, however, my vdroop gets soo damn high up there... I'm curious to see how the L709s compare with the L647s. Right now the L647s clearly lead the pack on the official OC board.

:D I had to do it. I was the first E6420 OC, then quickly became middle of the pack. I had intended on making 3704Mhz, but just couldn't get stable. I really need to do the p5b vdroop pencil mod, but it's a little scary. My vdroop was getting bad up there around 3700, I may make one more run...

You're Orthos stable at those speeds?! What is the week/processor code of your E6420!?

Wow, just took a look at your sig. Nice rig! We actually have a very similar cooling system, although I have a dual radiator configuration so I can fit it inside my P180. Also, using the Apogee GT and chipset cooling. I'm just happy I've taken back the top for now. Not sure if I'd be...

I'm a little stumped on this one. Perhaps just a case of the new mobo (and bios) blues... Anyone have more ideas?

Ah, point taken. :p By the way, grats on your stable overclock Evoic. Just noticed it in the Official OC Database thread.

Careful there, Double the heat of 50C is 373.15C

I guess I'm lucky, my girlfriend tends to just ignore my tech budget... I just tell her it's for work. ;)

GPU, not any that I know, but Speedfan is detecting my HDD temp right now. (It doesn't get my RAID array, but I leave that fan at 100% anyway)
