What is your RAM config? You should be under 24 with that speed.

Prime95 stability

This is quite a long thread and I have looked at a few pages here and there. Seems like a pretty impressive architecture, yet I can't help but stop and think: Intel is not stupid. Intel is a massive company and they are very resourceful. If they thought dothans would rake in the cash, they would have done it.

But what is the longest that anyone has primed their machine for? If anyone has come across anything they would like to share, that would be great. If not, I'll just start another thread and hopefully I would get some responses then :)

Intel knew they had a good chip in the Dothan, as a laptop chip its second to none. Dont think they thought it would come to the desktop though.
Have primed for 21 hours without issue, and numerous 12+ hour sessions. Chips dont get hot at all, even with fan on 50% :)
Read through this thread, its 58 pages but well worth the read. Some really useful info inside :)

Thanks for the reply. The only time I would have for reading 1000 posts on an one CPU (filled with wow this and wow that) is when I am dead :D

21 hours... Thats very impressive. Overclocked I assume? :)

Yes, cant remeber what speed this was at, 2.5ghz iirc, will dig out the screengrab for you later on :)

at the moment I have primed my 740 at 238x10 for days and it is completely stable

Of course you understand me being an AMD fanboy, I am quite astonished at these results. I mean a very low end processor like that is able to match and overcome an overclocked fx-55 CPU which is worth around $1400 (CDN).

My question was directed with intent of trying to find a flaw with these monsters and this was the one I came up with :D . Don't worry, I'll keep thinking really hard and I hope I can find a reason to justify getting an FX-55 for overclocking instead of a dothan... :) (of course there is that whole motherboard support and compatibility, as well as things like SLI and Crossfire which I doubt would be available for Intel mobile chips any time soon).

Assuming money is no object, and you aren't doing video encoding, the FX probably still leads, only because of better mobos. This CT-479 is a smart idea from Asus, but it really is a half-arsed jury-rig. If someone launches a 479-native board with dual channel and all the bells and whistles, like the DFI 875-T, then the Do than would pwn.

:soap:

With that said, I am now hooking up my cascade to my Dothan to kill all FX's in pi. :lol:

Everybody seems to be using the p4c800-E version...
Does the -E version clock better than the non-E version?
Does anybody know that? :)

-E version has intel RAID and Intel gigabit adapter, non-E version has Broadcom gigabit adapter and no intel RAID, otherwise, they are completely the same!

after few days of intensive BOINC at 238x10, I have finally managed to bot and for now stable at 239x10, which was impossible before with a voltage even at 1.6, now, I have it at 1.475, which translates to 1.44V actual

Do you think it would be possible to start a thread where JUST results are posted? It would be interesting to compile the data for a comparison between the 730s and 750s as well as between the p4p's and p4c's. This 25 page thread is getting a bit cumbersome :o

Hopefully through doing this, we can figure out what "tricks", which motherboard, what voltages, and what RAM these chips like the best :)

yeah, that's the stock cooler... with a Zalman 7700CU I can go about 2840mHz.... with the stock cooler and 1.53v I run 24/7 at 2700mHz.

Hmm, I have the same cooler.
But can't get past 2700Mhz (P-M770), sounds quite dissappointing cos I had 2751Mhz with my previous setup (aopen i855 + P-M715).

I hope the droop mod helps to get higher clocks.

Edit:What is your room-temperature? I think the 30+*C is killing the OC :slap:

yeah, my ambient is about 24c...

@ Charlie, did you have to do any mods to reach 295Mhz?
Cause that's a mighty fine mem speed you got there :D
