Hi, I'm in a dilemma. I currently have obtained the following:

SL9UL 2.66 GHz QX6700 B3

But can get one of the below in exchange for the above:

SLACR 2.40 GHz Q6600 G0

My motherboard is the Asus P5W DH Deluxe. Which one would you want? Keep the QX6700 or opt for the cooler G0. I plan on overclocking. Currently I have the QX6700 running @ 333.33 x 10.

Any help or advice would be greatly appreciated.

If you think you would ever drop the 10x multiplier for the 9x and push the FSB higher.. I'd get the G0.

This one is too easy. A G0 Q6600 will OC just as well and run much coller. Or you could wait till the Q9450 which will be at 2.66GHz and be better than both.

Do you care about the power consumption? If no, then keep the QX6700.
It is a QX6700, right? The EE version? Why would you want to let it go for a Q6600? G0 or not, it should come unlocked, and overclock well.

Unless you are going to get a monetary value back for the difference in price, I would keep the QX6700.

I'd be more worried about HEAT production than power consumption on that QX6700 clocked the same as a Q6600.

I still wouldn't trade it for a G0 Q6600.
I would look at another HSF or water cooling, before trading it.

gwolfman, I'm sorry to pop your bubble, but if you intend to overclock either the QX6700 or the Q6600 beyond 3.0Ghz using your P5W DH Deluxe, then you will need to replace it. The 975X chipset memory controller is not capable of handling the memory throughput required to maintain a stable overclock on a Quad beyond 3.0 to 3.1Ghz, regardless of FSB / multiplier / memory settings. A 965, P35, or X38 chipset based motherboard will be required if you'd like to push for 3.6Ghz.

Also, cnumartyr is correct. The maximum temperature specification and Thermal Desing Power (TDP) between the 95 Watt Q6600 G0 Stepping and the 130 Watt QX6700 B3 Stepping are significant, which effects overclocking ceiling and CPU Cooler selection, and should be carefully considered.

From the Core 2 Quad and Duo Temperature Guide: http://www.tomshardware.com/forum/221745-29-core-quad-t...

"...Section 6: Scale...

...Scale 2: Quad

Q6600: Tcase Max 71c, G0 Stepping, Tjunction Max 100c, Vcore Default 1.372, TDP 95w, Delta 10c

-Tcase/Tjunction-
--70--/--80--80--80--80-- Hot
--65--/--75--75--75--75-- Warm
--60--/--70--70--70--70-- Safe
--25--/--35--35--35--35-- Cool...

...Scale 3: Quad...

...QX6700: Tcase Max 65c, B3 Stepping, Tjunction Max 100c, Vcore Default 1.372, TDP 130w, Delta 10c

-Tcase/Tjunction-
--65--/--75--75--75--75-- Hot
--60--/--70--70--70--70-- Warm
--55--/--65--65--65--65-- Safe
--25--/--35--35--35--35-- Cool..."

If you're satisfied with 3.0Ghz, then keep what you already have, however, if you have the need for speed, then I strongly recommend the Q6600, and a P35 chipset based motherboard.

I think so, I'm just worried about my max FSB overclock for my particular motherboard. I had trouble getting over 380MHz (which is low, but a norm for this board) on my E6600. If I can get 370MHz (to match the speed of 333.33*10) then i'd be happy because it'll run cooler and overclock better when/if I get a new motherboard.

I do not care about the power consumption, but I do care about the heat generated, which is basically the same. Yeah, it's the EE version. I was thinking of letting it go since it runs cooler and can overclock better, but with my current motherboard I don't know if it'll make a difference (see 1st comment in this reply [above ^^^]). No monetary return, it's for a friend so it'll ammount to good karma at most. :)

Yeah, I don't know if it's worth buying a new motherboard since the Nehalem (sp?) chips coming out in a year or so will not work with the motherboard. Hard to decide.
November 21, 2007 3:31:24 PM

I disagree.

We have no idea where the market will be in a year.

At the moment you can get a P5K-E, Q6600, and 2 GB of Ballistix DDR2-1066 for ~$530. It's never been a better time to upgrade.

We have no clue if Nehalem (Intel's first IMC and Native Desktop Quad) will be great. It maybe plague with issues.. who knows. It might be expensive, might be cheap.

We do know this. DDR2 Memory prices are rediculously low. Q6600 G0s are underpriced for their value and a paired motherboard is no problem.

On the contrary, I can't think of a better time to upgrade.

Well, I have everything I need but the motherboard. And you have a good point. I'm leaning towards the G0 now if I can find a way to convince someone to buy me a motherboard for Christmas, 'cos I know it's not gonna be my wife. LOL

Hope you can find someone. I did my homework and I've found the P5K-E has some great overclocking results for the price on a quad core.

cnumartyr, I can vouch for that. I am extremely pleased with my P5K Deluxe, and impressed with the chipset, the overclockability, stability, and the Vcore damper feature. It's an excellent board.

8 Phase power + Voltage damper is what I'm gunning for!

48 mV vDroop Idle/Load on my current board at 3.2 GHz.

It's gone over 100 mV when I load it up at 3.5 GHz. I'm just not happy with that.

My Vcore typically sags 8 mV, and the extreme limit that I've seen is 16 mV at 3.7 with Prime95, virus scan and ATI Tool artifact scan running simultaneously. I used to have an MSI K8N Neo 4 Platinum paired with an Opteron 170 OC'd to 3.0, and it would sag 80 mV, which in turn required higher Vcore settings to compensate, resulting in higher temperatures. I couldn't be more pleased with this board, but just the aspect of the Vcore damper is what soid me over the less expensive MSI or Gigabyte boards.

That makes me drool. It'll be getting the P5K with some air testing and then it'll be going under water hopefully right around the first of the year.

I have some serious case modding to do with some new mesh sides and top along with custom radiator mounts to get built.. Unfortunately I'm also busy at work at the same time. =/

Or sell the QX6700 for $600-700 bucks and get 2 Q6600.

gwolfman,

Both chips will get to 3.0, and most likely 3.6 with good cooling.

November 21, 2007 8:04:28 PM

It's listed on Newegg for $925.
I'm sure someone will pay $200-250 less for it. Hell, call it the highest enthusiast 65nm CPU in the market. That will get someone to bite on it.

Look at eBay and see how many QX6700 are for sale, and how many bids there are. Right now, I see one with 5hrs left at $475.

So, if you can sell it for $500, that's still enough to get you a Q6600, and have some change left over, depending on what part of the world you are from.

Or, trade it. I still think you have a better overall CPU, since the 130W is TDP, and not average power. Yes, it might run a bit warmer, but to me, it's a downgrade, unless you are looking to do some serious overclocking. Just the unlocked multiplier makes it a bit better than the Q6600, imo.

So.. if you want to do serious overclocking it's a better idea to get the Q6600 G0? If you make that statement why would having an unlocked multiplier for overclocking make the QX6700 better?

I never said that it's a better idea to get the Q6600 G0 for serious overclocking.

I said it might run a bit warmer, but unless you are going to do serious overclocking (I never finished my thought there), then an exotic cooling will be needed.
If the QX6700 pushes 3.5GHz, but the OP wants to hit 4GHz on air, good luck. Even the Q6600 won't hit 4GHz on air.

That's what I meant to say. Sorry for the confusion - serious overclocking will need an exotic cooling solution, no matter the CPU used.

Lol.. ok sorry for the misread. And yea I agree.. 3.6-3.8ish is the "upper" limit on the G0 Q6600 for OCing. The other benefit is that it is also able to deal with more heat and put out less. Tcase Max on a G0 is 71. In the low 60s on a B3 QX6700 I believe.

I know the upper limit from experience.. I'll be putting it under water because I'm not going to be restrained by air anymore!

No misread, I just forgot to end my thought correctly there. No biggie.

Yes, the Q6600 G0 might have a bit more headroom due to lower temps, but how much does one want to push for a few more FPS or benchmark scores?
I have just a dual core E6700, and it runs all my games fine, and does it while I am encoding a DVD, with no problems. I can overclock it, but why? I don't need to right now. And I'm running it with a Swiftec H20 Premium water cooling setup. Am I worried about it, nope. Can I overclock it? Sure. But again, I don't need to, so I don't.

It's all up the OP, and what he (or she) wants to do. Either keep it or trade it, but I don't think he will go wrong with either choice. Just get a better cooling setup (water, phase change, etc) if you want to really push that OC.

Looks like I was able to pull it off. Now, which motherboard to pair with a Q6600 G0? P5K-E looks good. Any other ideas? Want at least RAID, eSATA, and firewire, and DDR2. I don't think the other options matter too much. Well, other than the fact that I need good quad core overclocking.

Any of the P5K and up series are great for OCing quads. 8 Phase power and Voltage Damper options in the BIOS. Very little Vdroop, good consistent power.
November 23, 2007 5:20:07 PM

For your quad, anything with a P35, or X38 chipset for crossfire, and the 680i chipset for SLI.

Look at my sig, I really like the Asus Maximus Formula SE, got my B3 to 3.74, and I run it 24/7 at 3.0 with only 1.22v (but the maximus does not have e-sata).

Before we get off track,

(1) the P5W-DH is perfectly capable of running with a 400 Mhz clock, giving you 3.2 ghz with a Q6600 at 8X. But it is a problem pushing the fsb HIGHER than 1600.. My Q6600 B3 has been running at 3.2 Ghz on a P5W-DH for several months, stable as a rock. My Q6600 G0 on a P5K maxes out at 3.24 Ghz.....

(2) there is NO DIFFERENCE beween a late run B3 and a G0, the thermal specs were adjusted since the B3 had ACHIEVED a lower thermal dissipation, There was no die change that suddenly made for a cooler chip. The G0 did have some bug fixes requring new microcode. The B3 will overclock equally well as a G0, at the same temperatures;the Run number (74al etc.) and Vid are the two things affecting overclockability.

(3) Thus you would be a fool to trade a QX6700 for a Q6600, any version, the other fellow would be laughing afterwards. And a P5W-DH is fine for now, until you get the exact board you want.

But I had a hard time getting my E6600 over 380MHz FSB, so I ran it at 375MHz. So, how am I supposed to get the QX6700/Q6600 over that when a dual core couldn't?

I had an E6400 running with a 395 fsb (3.15 Ghz) on the P5W-DH, I think you'll find it's other settings in Bios that have to be changed, or the E660 was a bad overclocker.
