QX6700 B3 or Q6600 G0?

[Warren21]

What would prove the better overclocker? I am aiming for whatever I can get out of a Scythe ASM w/ Ceramique (or AS5, I have both). I have heard of people using this cooler to cool the 45nm C2Q's to 4.0GHz, but of course their heat output is also lower. I can't run the Q9xx0's on this chipset (RD600), and I don't plan on swapping mobos until Nehalem (new socket). Right now, I can get either processor for roughly 300$, so the potential price difference is a non-issue.

I know the only tangible difference between the two (besides the stepping) is the multi, and because of that the only thing limiting the OC on the QX would be heat. Is 380 x 10 (3.8) realistic on good air with a B3 C2Q? Do I have a better chance going 400 x 9 (3.6) on the G0 Q6600? Do B3's require a lot more voltage?

I know there is the stigma that G0's have more headroom than B3's, but it seems to be very close. What am I to do?

I appreciate your anticipated help.

Well if you can get them at the same price I don't see why you wouldn't get the QX6700, that 10x multi would be handy on my Q6600, the 6700 will probably overclock a tad higher too.

The G0 stepping 6600 may very well OC better than that B3.

I vote the Q6600. Almost guaranteed 3.5 Duvie has a B0 ES (I think thats it), and I think his best is 3.4

 

[krnmastersgt]

I must ask you Mark, are those G0s running BOINC at those clocks?

 

[Warren21]

Thanks for these fast replies.

Krnmastersgt, AFAIK the multi is unlocked in both directions on the QX6700, so that means I can also use 11 if I so choose.

Does anyone know what kind of voltage difference is necessary for the same OC between G0 and B3? Temp delta at same speeds?

I run F@H 24/7/365

As for the voltage diff, all I can say is the B3 takes more vcore, and runs hotter, and won;t OC as well (see sig)

I don't understand why people run FaH on their CPU when they could get one of the ATI cards that are 30x faster than a CPU? Enlighten me?

 

[krnmastersgt]

I have too many problems with F@H so I just do BOINC o_o

 

[Amaroque]

Another vote for the G0. I have a B3 myself. If I had waited a couple months... Well, it's hard to wait! lol :laugh:

Warren21 I have both G0 Q6600 and B3 QX6700.

One G0 in the hand is worth two B3's in the bush.

Caveat: I have no idea how FSB overclock friendly your mobo is. On an i680 I would take an unlocked B3 over a locked G0 any day because of those damned FSB holes. But on P35 overclocking my G0's is smoothless and easy.

If you know or have reason to expect your mobo to be FSB overclocking unfriendly then go with the B3 as clicking up the multiplier is easy.

A G0 will OC higher, hands down.

Mobo dependant. I could not get my G0 to overclock worth a damn on my i680 Striker Extreme because of FSB holes, but on a P35 I can click thru the FSB setting left and right. So yes G0 no question if paired with an able mobo, the OP specifically stated no plans to upgrade their mobo.

 

[Warren21]

Yeah, I've got a DFI ICFX3200, that uses the venerable ATI RD600 chipset. The ICFXs OC well for their age, but I'm not sure about this 'FSB holes' thing -- or rather I haven't experienced anything like that, I run 8 * 400 fine 24/7.

Very simple. I have 4 ATI X1900XTs, 512 meg. They get less than 1000 PPD. I get 4500 PPD out of my Q6600's. Why would I use my video cards ? also they put out a lot of heat, and noise.

Yeah, but you are comparing one vid core to four cpu cores... not really fair!

Actually, comparing how much power an X1900XT eats while folding, yes it is. For points SMP destroys GPU folding atm.

Then you'll liekly have zero issues with overclocking a G0 (or a B3) via FSB settings...in which case my experience with both G0 and B3 would lead me to solely recommend the G0 over the unlocked B3.

Unless you are interested in buying my unlocked B3? (would love to replace it with a G0) Then I'll recommend my B3 above anything else you are looking to buy

I think Markfw900 answered the original question, which was not a question of "normalized per core, per watt, per xtor count, per $, etc". The question was: "30x higher than a CPU? Enlighten me?"

Mark answered it with ample room to spare. If I had a 3.3GHz quad and an ATI X1900XT card then there is no doubt which resource I'd bring to bear on F@H...and it wouldn't be the one which is "30X faster than CPUs".

 

[Markfw]

I even tried the GPU and one SMP, and the SMP destroyed the GPU on points, so I killed that, and fired up another cpu core on the same box, and it still puts out way less heat. If it really processes 30x (like the Panday group says) and they gave 30x points, then I would use it. I have for of those cards, and I did use them last year at this time. I use whatever puts out more ppd at less heat and power. I am paying the electric bill.

OP: You get the Q6600 G0. Like many says, that's probably a better bet overall. But kindly PM me with the information regarding the QX6700 for ~$300. I'd very much appreciate it.
