Should I get an E6750?

[t_ski]

I am currently running an Asus P5W DH Deluxe with an E6400. This chip can do 3.2GHz at 1.4v, but given this overclockability of these boards, I am probably limited to 440 FSB max and therefore 3.52GHz max.

Now I've got over $200 burning a hole in my pocket and I'm thinking about a CPU upgrade. I know a Q6600 is out as they don't do well on 975X boards, but what about an E6750? They have 4MB cache (instead of the 2MB on the E6400)and a 10x multi, which could allow me to go higher than the chip will. Ironically the E6600's are more than the E6750, but is that for any special reason? I do know the E6750 will be a G0 stepping...

Are the E6750's good overclockers? Will the extra 2MB cache make any difference? Any advice would be appreciated.

EDIT: OK, I messed up . I thought the E6750's were 10x @ 1066, not 8x @ 1333. So now I'm asking if I should get an E6600/6700/6850.

EDIT AGAIN: I bought an E6850. If you want to talk more about this chip, then post, but I'm no longer looking for suggestions.

why not sell your e6400 for 100 bucks... take your 200 bucks and pick up a e6850

Thats the route I would go

 

[t_ski]

Yeah, that's a possibility, but if I went with the cheaper CPU I'd have an extra $100 to put toward a second HD2900XT

Edit: Aw, crap - I just noticed the E6750 was 1333 FSB, not 1066 like I though. Duh, that means the multi is 8, not 10.

Wait for the E8X00 or QX95XX out next year.... that should be fast C2D.... i cant wait to get them....

Quads are out for me - I don't feel like upgrading my mobo for a new CPU

your mobo is compatible with quads afaik

well my 6750 does 3.6ghz for 24/7 at 450x8 at 1.425v.runs very cool too.

 

[reueljoab]

E6750 is a very good processor... i run mine at 3.48ghz 435x8 at 1.3875v.

I was then about to burst your bubble and tell you taht m8

The E6700 is a very good CPU (because of the 1066fsb and 10x multi)

 

[Lt_JWS]

Well like you say the P5WDH's aren't exactly known for great FSB speeds so you should probably keep what you've got unless you get get something with a 9x Multi. But all in all the E6750 is a great CPU for the price

 

[t_ski]

Correct, my mobo is compatible, but the 975X chipset is not good for overclocking Quads. If I got a Q6600 I'd probably be looking at a max of 330-340 FSB, which only gets me around 2.6-2.7GHz. Those numbers come from the "P5W DH Problems and Fixes" thread over at Xtreme Systems.

But since I mistakenly thought the E6750 was a 10x multi, I have now changed the thread to E6600/6700/6850.

id get an e6700. cause of the multiplier :> ps : what mch voltage you using on ur 975x

 

[Deleted member 24505]

a 6700 is'nt a G0 tho' is it? the 6750 will run cooler for a given oc,but the 10x multi is useful.

 

[t_ski]

ps : what mch voltage you using on ur 975x

IIRC it's 1.6v for 400FSB. I figure I'd have to max it (1.65v) to get up around 440.

Yeah, the 6700 isn't a G0, but I think I need the 10x more than the reduced heat output.

that sounds crazy - I run my e6400 at 3.2g / 400fsb @ 1.365v and it's 8+ hrs orthos stable

what bios are you running?

 

[Deleted member 24505]

s'ok bud,i can dig that.a 10x multi is good for ocing,easy to work out clock speeds.

No, he was asking about MCH voltage, not vCore. vcore is only 1.4v (in the bios) for 3.2GHz.

Bios is the latest (2205 IIRC).

 

[TUngsten]

phew!
I think you can safely run the vMCH at max (1.75v) provided you have decent airflow in your case. I've read a lot of RAM settings posts at the various memory manufacturer techsites (OCZ, Corsair etc) and most of the OCZ techs recommend that voltage for OCing their ram

 

[t_ski]

Yeah, I was thinking the max MCH was something like 1.75v, but I looked in the manual and only saw 1.65v. Doing some testing at stock speeds right now but I'll reboot in a little bit to OC it back to 3.2GHz.

Thanks for the tip - I'll have to go see about some G.Skill timings (right now it' @ 4-4-4-12).

 

[t_ski]

MCH is running at 1.75v, but max is 1.85v. I'm willing to watercool the chipset if needed.

 

[DOM]

have you tryed finding th max bus speed on your mobo ? by lowering the multiplier ?

 

[t_ski]

No, I haven't had the time to tinker that much with it, but around the net a stock P5W DH is limited to about 440 FSB. With vmods, it can go higher.

 

[DOM]

what kind of oc are you looking to get 4GHz+

Hey d44ve, I have read that only a few motherboards support this CPU{E6850},..sounded fishy to me but I wanted to ask you.
