6600 Retail, initial overclocking results..

Just got my retail 6600 from Newegg and pulled out my Pentium D 805 which I had been running at 3.33ghz steady for about 3 months. Was able to run SuperPi 1M in 32 secs on the old 805 and had a 3dmark05 score of 8205 with a 7900GT.

With the new 6600 at stock 2.4ghz speeds i'm able to run a SuperPi 1m in 21 secs and 3dmark05 has bumped up to 9138. Temps are 49c motherboard, idle 28c, load 41c.

I was hoping for something magical like i've seen some people hitting 3.6ghz (400mhz fsb) on stock voltage/air so I tried for that and got a dead boot, rebooted and went back in and dropped it to a more conservative 333mhz fsb and everything loads fine, and games run fine, but Prime95 and Orthos return immediate errors. After tweaking the stock voltage from 1.325ish (as per cpu-z indicated) up to 1.34 and stepping it down by .025 increments I found that i was stable at 1.3625 Prime95 and Orthos after 6hrs of testing so far. Temps with this OC are 50c motherboard, idle 29c, and load 42c.

Initial testing shows 3dmark05 up to 9347 and SuperPi 1M now completes in 17.082secs. I've read that disabling the Hyperpath setting in the bios (Asus P5W DH) allows for more stable OC's over the 300mhz FSB "wall" but I've noticed no difference. I may try more fsb/core voltage but for now I think this is pretty decent, a mere .040 voltage increase for a nice hefty 25% OC isn't bad and the new results in Sisoft Sandra and Everest look quite nice. Running some Corsair DDR2-800 memory as well so that probably helps the stability.

If anyone has some tips on any tweaks for this motherboard or any other testing methods i'd appreciate the feedback.

You have the same stepping i do , go on give it some more welly.

You can do it , i am depending on you , the stepping needs you to proove its capabilities , if you check the leaderboard we could do with a few more of stepping B2

Good one and keep it going as long as you can, what you using for ram and coolling.
 
It'll take 3.2GHz easy with a little more VCore = 15s Super Pi times. :)
 
Same results on my P5W DH as my DS3...virtually NO CHANGE.

I've tried all different settings - same thing.

3.2GHz @ 1.45V stable
3.3GHz @ 1.50V stable
3.4GHz @ 1.6V stable

This is what pretty much all retail E6600's on good air are doing.

Same stepping I have and .2 faster than mine.

lol that's 100% accurate of what I encountered while o/c'ing my retail (B2) e6600

Although there's a few lucky bastards out there who got a REALLY good one. There's a guy on xs forums that got a week 25 retail E6600 to 3.6GHz stable on air with 1.475VCore!!!

SO JEALOUS. Ugh. That's 400MHz better than my chip at basically the same voltage! :mad:
 
Mine only seems good for 2.8. I thought 2.9 was gonna be fine but I got a random reboot, which is the same thing that happens @ 3Ghz. Also mIRC freezes up on me @ 3Ghz which is wierd, wouldnt' think some little IRC app like mIRC would not work, but it just plain won't @ 3Ghz. Sometimes @ 2.9Ghz it doesn't either. I tried all the way up to 1.5v and also tweaked up voltages on FSB termination, the NB voltage, and also disabled the CPU things like virtualization, speedstep, etc. It's just not stable above 2.8Ghz. Kinda sux but a 400Mhz overclock is ok I guess.

One thing that has me confused is to overclock to anything I hafta set my memory speed down all the way. Like right now my mem is at like 666mhz or something, and if I set it up to 803Mhz (which should be perfectly fine as it's 800Mhz mem and I was running it @ 834Mhz on my old setup), I will get no screen at all upon reboot and hafta turn my PC off and on multiple times to get it to reset back to default.

Mine is a week 23 B2!
L623A738

I don't know what in the hell it can do because my RAM is holding me back. I RAMed the first ZX batch to GSkill , it needed too much voltage and I had to use some cheap RAM and switchout after changing the settings. Wouldn't run stable at 667 and 800 was untouchable with it.

I was happy when I sent it back and GS rushed me some new RAM. I was hopeing for NR but got PK instead. The RAM boots fine but at STOCK 800 5-5-5-15 it can't pass memtest or Prime no matter how much voltage I gave it.

I feel ripped off! I've paid about $213 for $150 RAM that's still not Prime stable at stock.

Yes, I ran the small test to remove the RAM and the Proc did fine. I even lowered the multiplier to 7 X 400 and had it crash at only 2.8GHz. I did this after I had it at 2.88GHz for an hour of Prime and it past memtest. Oh well.

Its not bad i guess , you should be happy with that , at least its not your mobo and something else , CPU or Ram.lol

I have the L623A790 , its going to bring more surprises, generally i have seen our stepping gone to 4ghz on water though.

I do have a very nice pair of memory modules and will get a 590SLi board, i only want about 1ghz overclock and i am happy

I honestly like mine at 3GHz, I think I'm just expecting less here.

If you want a preview into what you'll get , mine is the same exact chip batch as you, L623A738. I've found similar OC's as Brahmzy's post. My best stable OC at reasonable volt is 3.2 ghz at 1.4625, it's in the overclock database.
