I'll be surprised if you don't find close to 2.9 in that thing on air. The core temp issue is certainly strange, but it can be a funny application with AMDs prior to AM2. I've had it do similar things with my FX-60 from time to time.

Results: cpu fails at any voltage under 2900 or 3Ghz.

Temps under 2808 Mhz are way high sometimes on core temp, but my case sensors, motherboard sensors and aerogate doesn't show me the same high temps.

I maxed out at 2808Mhz, 9 x 312, memory at 255Mhz, vcore at 1.47v on bios, show as 1.44v on sensors.

Can't complain about the overclock, but I don't think I can reach 2.9 or 3GHz with this chip.

2800 was about my max on air that I could call truly stable.
I didnt get to 3GHz til I went with better cooling on this CPU.
Consider putting water on it.....or a TEC like the one I use.

Cris-
You say the RAM is running at 255MHz? You said it was Value Select Corsair but I'll assume it is DDR500 stuff like mine. Put it on the 133 divider for now and keep working the CPU. Forget about the RAM, let it run at 200MHz, it is irrelevant until you get the CPU maxed. Once we see if you can get that CPU past 3.0 we'll get back to the RAM.

Wanna and I have virtually the same performance and there is no reason to assume that your CPU is any different. Set the RAM to dead slow and HT to 3X and work the CPU for now.

Maybe in the future. Water based solutions costs more than a 8800GTX here

And I can't find a swiftech product or something like that in Brazil.

Pumping up the RPMs on the panaflo I can run it better, but there's no way to fight a 30°C+ ambient in the middle of summer.

Same chips on Corsair 4000PT or gskill HZ, same pcb.

I can reach 270Mhz on that ram on a dualcore processor.

DDR500 or 600 are just a marketing way to name DDR400 sticks who achieve more speed than the usual DDR400 JEDEC specs.

I left my ram on low dividers all the time, stressing and -*test*-('")ing only the processor. Since it doesn't reach more than 2808 100% stable I started working on the ram.

It's REALLY hot here today, heat should be killing my overclock.

I can relate to that Chris...here in Florida where I live in the US, 30c is the average
daily temp. I am just lucky that Mercs lil Super Pi run off coincided with a very cool
part of the year here. Having temps 0f 20c or lower ambient helps a bunch for sure.

Funny Wanna, my wife was mad at me I would turn the heat on...LMAO

Merc......
JNav89GT put the Team Group ram he reviewed that I posted earlier up for sale.

Chronos PC4000 CE6 Infineon based did 275 3d stable for me $175 2x1gb retail kit



http://www.xtremesystems.org/forums/showthread.php?t=125546

After 2 days working on the chip:

- Maximum orthos stable clock that I have until now: 2808Mhz

It needs at least 1.47v on bios, which shows up as 1.44v on sensors.

Anything below 1.47v on bios and it fails orthos after some hours of -*test*-('")ing.

I could not reach stable 2900 or 3000 Mhz settings. 3000+ needs at least 1.5v on bios or it doesn't even boot Windows.

After tweaking it into 2808Mhz, I started working on the memory and at this moment it runs at stable 255Mhz.

Maybe I can -*test*-('") it under 8x multiplier. I try that today.

363 x 8 as a start

Cris-
Can't you go over 1.5V in BIOS? Anything up to 1.55v is fine in my book. 1.55v to 1.59v is OK but puts some heat out. I like to keep it below 1.55v if possible.

Also, if you're getting a dip from 1.47 to 1.44v thne you need to take that into account. Set Vcore to 1.5 v so the dip is to 1.47v and see if that stabilizes it enough to move up.

Wanna-
Is that RAM for sale from you now or was that earlier?

I can go up to "let's start a fire at the case" voltages, but I don't wanna lose this chip trying to gain 200 Mhz.

The "dip" on vcore is a "feature" of the mobo since people used to burn out chips when it was released. I really don't know if it's just a sensor measurement or if it's really at 1.44 when set to 1.47v.

I'll try new settings later. Heat is a problem here for 1.5+. If it was a "good" chip, I would be able to reach 3Ghz with 1.45 or something.

I think that 56% above usual clock is already awesome.

That 2GB kit of ram is for sale in the sale section at Xtreme Forums in this thread.

It was a review sample set that was used in this review by JNav89GT

http://www.madshrimps.be/?action=getarticle&articID=397

It has nothing to do with me.....
I just found it, and $175 seemed a sweet deal, and I thought of you.
Read the review(page 3) and see what you think....still for sale last I checked.
I'm afraid he may have the results of the 2GB kits mixed up in his sale info.
I thought he said the Micron did better then the Infineon in his review.
In his sale info it listed opposite that

334x9 fails even at 1.5v x 104.8%

Maybe I need a swiftech.

2907Mhz i a reality.

3DMark stable. Guess I'm tired of Orthos and that damn volcano



Watercooler or anything better needed for 3Ghz.

Doing a comparison between 3Dmark 2006 performance between stock Core 2 Duo E6600 and Opteron 165 at 3Ghz.

Opteron at 3Ghz wins

Ya your stuck right where I was with the air cooling and hitting 3GHz Chris
