Quick Question Re: E6600 vs. 6750

I have the opportunity but have to act within an hour. Should I keep my E6600 or upgrade to a 6750 for 20 bucks? Given that the E6600 has a higher multiplier will it OC better? Which is hotter? Any advice would help given my extreme time limitations to choose.
 
Nah, waste of 20$.

A E6600 has a 9x multiplier to your advantage while the E6750 is just 8x. You can technically bump the E6600 to E6850 just by upping the FSB to 1333, which is very easy. At the base, both is the same core, same 65nm process so both should behave the same.

 
Stick with the E6600, it will give you more overclocking headroom and put less strain on the mobo at higher speeds since the FSB will be lower.

I agree 100% with this .
The E6850 is just an E6600 with a FSB of 1333 instead of 1066..
You can make your own by upping the FSB and save your $20.00..:)
 
Guy called me back and he is now going to be 3 hours so that gives me some time to play. I ran some real rough and fast benchmarks on the E6600 clocked at 3.0GHZ and then swapped in the E6750.

Right off the hop I can say that the E6750 is MUCH cooler. At idle with my E6600 at a 1333 FSB X9 and therefore 3.0 GHZ it idled at 30C on both cores and after 5 minutes of Orthos (time limitations here) it ran at 52C on both cores.

The E6750 ran idle at 16C both cores and 33C after 5 minutes of Orthos. This is impressive considering the arctic silver hasn't had a chance to settle in like the E6600 which had been set in place for weeks. Next I will put it at 3.0 GHZ to match the E6600 and see what happens.
 
Quick question. Please don't laugh as my teachers always told me no question is stupid =-)
I have heard that CPU's need to "burn in" like a new engine in a car. That I shouldn't OC until it has run at stock for several days. True or false?

Cant say if its true or false, but every CPU I have ever owned came out of the box and got clocked up immediately..:)
 
OK at 1500 FSB for 3.0GHZ it idles at 18C and after five minutes of Orthos it hits 34C. In Addition I ran 3DMark 05 on the E6600 with default install settings with the E6600 at 3.0GHZ and got a score of 16156. With the E6750 at 3GHZ I got 16523 which isn't surprising considering the faster FSB. However I kept the memory unlinked so that it wasn't a factor. I had reseated my E6600's heatsink 10 times trying to get the temps lower so I know it wasn't that it was seated properly. Therefore the biggest improvement I can see is the temperature. At 3.0 GHZ the E6750 is clearly 15 - 20 degrees coller than the E6600. That and its running at a faster FSB to get there. Can't wait to see how far I can push this. The best I could do with the E6600 was 3.6 with the core at 1.6 volts. Stay tuned.
 
If you get better temps with the E6750 systematically, then get it since it's possible the IHS isn't even on the E6600 and better on the E6750.
 
Coretemp Beta .95 reports 18C Idle. I live in Canada and my ambient is 18C. I wanted to be sure the reported temps were accurate.

These are my specs.

Coolermaster Conros 1000 with 6 120mm fans
Thermaltake V1 CPU Cooler
Asus P5N-E SLi
E6750 at 3 GH (FSB at 1500)
BFG 8800 GTS OC 320MB @ 600 Core and 850 mem
OCZ 667 MHZ Value Pro running unlinked at 850 with 4-4-4-8 at 2.0 volts
Audogy 2 ZS
Seagate 400 GB Sata 3


How many volts can I safely push through this memory. I would like to get to 1000 linked.
 
I don't really have an opinion on the proc, but I have an e6750 and it's absolutely amazing. Overclocked to 3.66GHz on 1.4vcore with a ThermalRight-120extreme it runs full load (24/7 Folding SMP) at around 55'C.

As far as temps, you're not reading them correctly. The e6750 is built on a 100'c tjunction whereas the e6600 is a 85'c tjunction. You need to add 15'c to your readings to have the correct temps in several monitor programs, especially ones that aren't updated regularly...
 
Sorry Lethal....don't really do forums much...just starting to read and post more often.

What is the best program to use with this processor for reading temps? Is there anything out there that is accurate?

BTW I am at 3.6 stable for about 1.5 hours. 1.4 volts.
 
Orthos 2 hours. Unfortunately according to Everest (apparently far more accurate) the cores are at 57 and 58. Not bad for 3.6 on air I guess. Probably a little warm for 24/7 use though.
 
You can offset the readings for Speedfan +15'C if you want, the new CoreTemp beta works, or I believe recent versions of Everest also work correct... could be wrong on Everest though.

I personally use CoreTemp beta. Simple and it works...

Yep...burn in, is 99% a myth. Most overclocking improvements are the result of minor changes in some other aspect of the system.
