Am between these chips. My aim is to overlock past 3.4Ghz. I hear that G0 chips have issues with Asus P5W 975 deluxe boards and its northbridge chip which can't hold up high fsb.

I would get a E6850 if am convinced that ill be able to overclock it 9x400 without problems with my board and without reaching an fsb wall.

Since the difference between these chips is minimal am seeking advice regarding what would be the best buy for me, taking into accoumt my board. Thanks
 
i have a E6750 and OCed to about 3.4 @ 425FSB i think if i got a better case with good cooling i could get it higher!!#

i vote E6750 as E6850 u would be better going quad!
 
Quad have some problems with certain applications, is that true? Thats why i hesitate qoing quad core.

I have found E6600 for 100 quid used. Do you think its a decent offer?
 
£100 is far too much for a used E6600, especially when you can get a brand new E6750 for between £112-115. As a side note, my 4300 is at 3.4ghz on water perfectly stable.
 
A cpu that's been lapped has been found to have a concave integrated heatsink instead of perfectly flat one. It means to you the prospective buyer that the previous owner discovered it was running too hot and used some sandpaper to try to level the heatsink. This voids the intel warranty unfortunately. Personally I'd be wary as it makes me think it may not be a very good clocker.

Its integrated Heatspreader. Also lapping is not done only on a concave IHS, some do it because it may provide a better mating with the heatsink and reduce temps a wee bit more by reducing any air gaps etc.. we've been doing this on heatsinks long before IHSes became a norm. A formerly concave IHS or lapped IHS has no bearing on whether the cpu may clock good or not, i've got 2 E6600 L629B with concave IHS and they clock higher than most G0 dual core cpus on a lot less volts as well and even lapped they run hot as its the nature of that particular stepping. I do agree 100 is a bit much now though, unless its a monster clocker on relatively low volts and its proven.

I lapped my e6300 and it was not concave. Didn't notice any temp difference though.
 
I got my E6850 to 3.6Ghz without changing anything other than the FSB. I then went to 3.8Ghz quite easily with some voltage changes. I haven't had the time to try for 4Ghz but I plan to.

In hindsight, I'm not sure if I should have gone with the Q6600 or not. I think if I had watercooling I probably would have.

Yea the 6850s seem to be made from better silicon :) One i had here clocked high on low volts as well and generally they're doing much better from what i see.

The members market has some deals.



The e2160 is great for the money but the E2160 at 3.0ghz is only roughly equivalent to a Conroe @ 2.8 or so

Where is the members market?


The problem with my case is that I have the asus p5w board for which reports say that you hit an fsb wall at around 420mhz plus some compatibility issues. That would prevent me from properly overcloking G0 processors.
