The QX6700 run normally with 2.667 GHz.
I have Corsair RAMs with "normal" 5-5-5-18 and you can OC them with 4-4-4-12 @ 2.1 V

I don't know about OC... ;-)
Only for info...
I'm sorry for this stupid question!

If I let run the QX6700 with a small OC at ~ 3.000 GHz (because I heard it's possible to this, without changing the voltage)(...then the PC have nearly the same power consumption) ...but/and I don't know with which RAM-settings...
or
at 2.667 GHz and RAM 4-4-4-12 @ 2.1V (because they have the "permission" to run CL5 and CL4) (then they will be much more hotter, so that I must cool them with fan?) BTW. ...then the PC have a higher power consumption?

what is faster?

Thanx!!



BTW.
SETI@home cannot destroy the RAMs or?
Because I bought a NEW PC, this QX6700, and he was running 2 weeks without probs, but then BOINC was from time to time frozen. Then I had let run Memtest86+ V1.70 and I had over 450 errors!!
O.K., I didn't let run the test before I started to let run BOINC on this PC, but it's possible that the RAM was damaged because of BOINC/SETI@home?

Simple answer is "no".

A slightly longer answer is that Memtest86+ will exercise your memory harder than s@h.

A more thoughtful answer involves noting that your PC component timings degrade as any part of the system gets hotter...


Improve your cooling?

Back off on the overclocking?

Note that reliability is much better than superfast corrupt rubbish!...

Good luck,
Martin

At what temp, for the Intel Duo Core E6xxx (I have the E6600), does it become a problem and a cooling upgrade is necessary.

Thanks, I'm running 24/7 and generally keep my residence at ~ 80 degrees (26.5C) and the processor is running ~ 53C-55C. I probably should get a better heat sink but I hate the idea of pulling the Mobo out.

Hey, any computer builders in the Phoenix area want to give it a go???

53°-55° is fine :) If you're not comfortable removing the motherboard and heatsink than it's best not to mess with it. Once you get the BIOS update for your P5W-DH and put in the quad, get a better heatsink/fan. Mine is now cooled by a Zalman after replacing a Thermalright and I'll probly have it online by tomorrow night (:D) after I complete transfering all my stuff to vista. So I'll download some temperature software a make a quick post here with my temps.

Thanks for your input, I was worried that 55 was getting into the problem range range.

EDIT:
"6400" (800 MHz) DDR2-RAMs with ("normally") CL4 (or lower) without OC are not available now, or?

Or maybe higher MHz-RAMs and lower CL?

You can still use 4-4-4-12 timings if you overclock to 3.0GHz. Preferably at 1T. If it doesn't work at 1T, try using 2T instead. The higher the voltage for your RAM, the more heat will be produced. In that case you should consider a RAM cooler, like OCZ XTC.

EDIT: I have 800MHz RAM at 5-5-5-15/1.9V to keep the heat down. Better safe than sorry ;)

mine is running at 3.7Ghz stable for months, with 800Mhz 4-4-4-12 and a MatchII active cooling. running temperature is -31 Celcius :)

it is crunching rosetta now.
the V8 will be running my new version by friday. I found my bug.

When you make your app public? :-)

Please can you show me (with link) a pic of the MatchII?
...I "googled" but I didn't found...

I contacted Corsair and they said, temps < 50 °C are O.K. ...
...but where I can control this temp?

I ordered now this:

It's for DOMINATOR... but for my xms2 is this good too I think...


BTW.
the QX6700 run well @ ~ 3.0 GHz without changing the voltage... I read...
...then the temperature of the CPU does not rise or?

Thanks for your input, I was worried that 55 was getting into the problem range range.

That's good compared to what I have right now. With a Zalman CNPS9500 my temps are 60C, 58C, 58C, 57C. I'll be looking for yet another cooler.

I was able to run my memory at 4-4-4-12 at 2.6GHz with 2T setting instead of 1T. I reduced CPU speed to default 2.4GHz but I think I'll leave the memory settings where they are unless it gets too hot.

...I'm a newbie because of OC... ;-)

My Corsair have 4-4-4-12-2T @ 2.1 V (XMS2 6400C4)

Hi Captain Future,

who? was talking about a "Prometeia Mach II" phase-change cooling system. It's a full tower case with an integrated freezer (like what you have for your "Kühltruhe" except more powerful).

The system itself isn't all too cheap, but it works well.

As for the 1T/2T, that's called "command rate" and it determines at what latency commands are sent, like the name says. Not many modules can run 1T at their rated speed; usually, you'll have to buy Corsair or OCZ or other high-performance RAM.

At the same MHz and other latency settings (4-4-4-12) you will get more performance out of your modules. For example, my PD 805 gives the same RAM performance at 675 MHz with 4-4-4-12-1T and 810 MHz 5-5-5-15-2T.

So, 1T really gives you a noticeable boost. Running DDR2-800 at low latencies gives almost the same performance as DDR2-1200 at high ones.

HTH,
Simon.

Some observations about Zalman cooler,

@A/C , I recently installed a Zalman cooler in my old p4 which always suffered from heat because it is in a uATX case. initially i wasn't getting any better temps than then stock hsink/fan , which suprised me as it is larger and copper.

So next I tried cleaning off the interface goo that came with the Zalman and replaced it with bog standard silicon goo from an electronics store, I now get ~28 degrees C at idle and < 40 degrees C full load, with fan set to minimum speed.

Might be worth a try ? the Zalman supplied goo was pretty thick stuff that came with mine.

with corsair RAM, On a different newer p4 I installed XMS2 5400C4 stuff, cheaper / slower than mentioned which also runs at 4-4-4-12-2T quite happily, This leads me to believe that the rating printed on the module is a 2T setting. I have not tried to push it any harder yet, I think the board's northbridge may need extra cooling, and that I'll have to read some more about the individual settings that make up that specification. It will br interesting to see what conclusions you guys come to with that ram you have.

[Edit: thanks simon for that description of command rate, I'll try 1T later on that p4 & run memtest86 for a while]

Jason,

that's the exact same memory I'm running at 675 MHz @ 4-4-4-12-1T on an nForce 4 S775 board (Asus P5ND2-SLI).

So it does do it at 1T, but you'll have to adjust the voltage to what the label says, as well. Mine said 2.1 Volts (vs. 1.8 default), and it's still under warranty at that voltage.

Using default voltage, I could only run 2T as well.

Regards,
Simon.

Cool thanks! I figured it would be something like that, pretty responsive as is but I'll give it a try later

A lot of people don't realize that. The performance difference would be greater if 1000 MHz memory was 4-4-4-12/1T and 800 was at 5-5-5-15/2T. In that case the lower CL-RCD-RP-RAS timings with lower command timing wins :).
