    lapping my Ultra-120 Extreme (pics and temp data)

    Thanks for the tip about RMClock, Graysky. I'd not heard of it. I'll probably hold off on any lapping for now, especially as I've now got everything reinstalled and running, but your results merit keeping an eye on things and considering that option if I see temps to ever be a problem...

    lapping my Ultra-120 Extreme (pics and temp data)

    Hello all, This thread caught my attention after having just purchased and installed a Thermalright Ultra-120 Extreme in my system, to replace a less efficient Zalman CNPS9500. Although the Zalman has worked fine and allowed me to stably overclock my Core 2 Extreme to 3.6GHz, that also...

    Well, I don't have a wife...45 and single still. But after going nuts this year and buying a slew of pricey toys, I don't think I really need a 2nd motherboard.....yet. ;) Daryl

    Hey SmokeDog, Oh, I don't take your comment as a taunt at all, but just simple truth. I can't very well return working products now, but your results do have me pretty much wishing I had at least not gone fully to the top end with the Core 2 Extreme. Frankly, it was the unlocked multiplier...

    Hi Skott, Yeah, for doing nothing more than swapping out the stock Intel cooler for the better, quieter Zalman and pulling off the heatsink "skins", I'm pretty happy with a 3.65GHz operation. I'm sure that variances between boards, chips, cooling, etc., can all add up to easily explain a...

    My Experience: Core 2 Extreme X6800 and Asus P5W DH Motherboard (a step backwards with Arctic Silver 5!!!)

    Well, I'm back to 3.65GHz, using FSB365 and all other settings unchanged. My system seems to favor that as its peak right now. At 3.7GHz I ran once again into a situation where there was simply some strange behavior in Windows...a pop-up about the wireless being connected would not clear, I...

    My Experience: Core 2 Extreme X6800 and Asus P5W DH Motherboard (a step backwards with Arctic Silver 5!!!)

    OK, it looks like I'm now successfully at a minor bump to 3.7GHz from my prior 3.65Ghz operation. With the same settings but bumping up to FSB372, my system wouldn't boot and I wasn't sure what to tweak. So, I'm sticking with 3.7GHz for now. In the process of doing this, I found that ASUS...

    Well Murph, 3.77GHz isn't such a bad place to be stuck at, and at least your wife isn't sticking you with her knitting needles! :)

    Hi Oscar, Thanks for the reminder about Q-Fan...I believe I do have it enabled and will double-check that when I get home tonight. I definitely know my rear fan is on a Chassis Fan header, because the Gigabyte case has the wiring for that fan neatly routed up and split out to the front fan...

    Hi Oscar, Yeah, that "gift wrap" around the heatsinks is just purely stupid in my opinion. However, I noticed in the photos of Smoke Dog's system that his Gigabyte board has received similar treatment and it shares a heat pipe design for cooling the NB akin to ASUS. I don't know anything...

    My Experience: Core 2 Extreme X6800 and Asus P5W DH Motherboard (a step backwards with Arctic Silver 5!!!)

    I've got nothing helpful to offer you Oscar, but I thought I would note that I went ahead and peeled off the ASUS cosmetic covers from the two heatsinks. That was easy to do even with the mobo installedl since, as you said, there was nothing more than a weak adhesive used to attach them...

    My Experience: Core 2 Extreme X6800 and Asus P5W DH Motherboard (a step backwards with Arctic Silver 5!!!)

    Hi Smoke Dog, That is definitely some impressive numbers and the one obvious thing I see here is that you're running on a Gigabyte board, so that in and of itself may explain the difference. I've seen a few posts elsewhere talking of problems on the Asus P5W DH with the Corsair DDR2-1066...

    Well, after fiddling around a little more last night, I'm running my E6800 rig at 3.65GHz, with FSB365, DDR2-730, CPU Multiplier 10 and all other timings and voltages being the same as what InterMurph used...I may have 2.15v on the DDR2, I don't recall for certain. I did have the system at...

    InterMurph, Thanks, but unless you want to search for the links on FSB1600, you needn't do so for me. Just your comments alone are enough to prompt me to do a bit of Googling for more info. In one such search, I came across a Dutch or German thread that led me to yet another site with what...

    My Experience: Core 2 Extreme X6800 and Asus P5W DH Motherboard (a step backwards with Arctic Silver 5!!!)

    InterMurph, Thanks...yes, I understand that DDR2 runs at double the CPU frequency, so no problems there. I was just curious if your suggestion was a recommendation or perhaps a rule I'd missed somewhere, and I see from your reply it is just a well-advised recommendation. I just got confused...

    My Experience: Core 2 Extreme X6800 and Asus P5W DH Motherboard (a step backwards with Arctic Silver 5!!!)

    Hi folks, Not a whole lot of progress here for me, as I'm still running FSB1066, CPU Freq. 266, DDR2-800, multiplier 13 for a 3.46GHz operation. What I did learn along the way however, was that while my BIOS was reporting the memory as PC2-5300, raising the memory voltage to 2.15v yieleded a...

    My Experience: Core 2 Extreme X6800 and Asus P5W DH Motherboard (a step backwards with Arctic Silver 5!!!)

    FYI to all interested....BIOS 1201 is now available, but I don't know what was changed. As for myself, I'm still running at 3.46GHz using a CPU multiplier of 13 with CPU freq. @266, DDR2-800 mode. Upping the memory voltage to 2.15v, I'm seeing the BIOS report PC2-6400 (rather than PC2-5300...

    Hi InterMurph, Well, congratulations on the 3.78GHz speed....that sounds pretty darn good to me. I've never read through this thread from start to the current end, but I see you started in the same boat as I did, with no overclocking experience. It seems you've learned a lot on the way and...

    My Experience: Core 2 Extreme X6800 and Asus P5W DH Motherboard (a step backwards with Arctic Silver 5!!!)

    Oh, no doubt about it InterMurph, my results are by no means solid yet...just a quick look. Somewhere yesterday I read a review of the Corsair 8500C5 DDRAM2 memory and it was reportedly working well for the author at 4-4-4-12. I don't recall for certain that they were running at FSB1066, but I...

    My Experience: Core 2 Extreme X6800 and Asus P5W DH Motherboard (a step backwards with Arctic Silver 5!!!)

    OK, I think I'm happy for now with how I've wired and cooled the interior of my Poseidon X6800 system rig. Via nothing more than a CPU multiplier change from 11 to 13 on FSB266, I'm running at 3.46 GHz. The memory is at DDR1066 with 4-4-4-12 timing. I'll fiddle with some more aggressive...

    Oh I definitely plan to explore higher performance overclocking, but first I'd like to see what I can do to improve cooling some. I'm clueless as to what would truly be considered too hot for good system stability and component life, but your numbers with the P180 case lead me to think that...

    Live and Learn! Or....don't I feel like a dummy! It seems the issue with my 1.6GHz Core 2 Extreme, was that I simply failed to change the CPU multiplier in the BIOS for the ASUS P5W DH. Over the years, I can't recall using BIOS that wasn't purely menu driven, so when I failed to see any menu...

    Hey InterMurph, Have you used the Ai Booster app any for tweaking your overclocking settings? I used it little last night and found a few cases where, after applying my changes, it failed to close out and reboot my system. I'm wondering if it is a rather flaky application and if it is...

    My Experience: Core 2 Extreme X6800 and Asus P5W DH Motherboard (a step backwards with Arctic Silver 5!!!)

    I got the BIOS version from within the BIOS setup...the System Information screen if my memory can be trusted. As you, I too suspect something awry with the BIOS however. and it's easy enough to first restore the default settings to see what they give, and then reflash the BIOS if I can't nail...

    Thanks InterMurph, I'll grab CPU-Z tonight and set what it tells me. As for the BIOS, the board came with 1101 already installed. Daryl

    Hello All, Well now! This is a handy thread to find, as I've just built a new PC, without reading the ASUS manual much yet, and my Core 2 Extreme keeps running at 1.6GHz, the multiplier seemingly locking in at 6 on a 266 FSB. Fiddling around with a few overclock attempts, the system...
