From: Daniel Mandic on 1 Sep 2005 16:25 The EE, I mentioned in my last posting is not a 478, as I suggested. Itýs a 775 Socket. So I stucked to a i865PE, ASUS P5P-800 SE. GfX we have is 8x AGP. What is the fastest RAM available? 2-2-2? We decided yet, using two RAM modules for a total of 1GB. Dual-Channel.... CPU is iP4 EE, 3.73GHz, FSB1066, Socket 775, 2nd-Level Cache 2048KB (150W :-)) Best Regards, Daniel Mandic

The P5P800 is FSB800. Try typing "P5P800" in the search box on the CPUSupport web page: http://support.asus.com.tw/cpusupport/cpusupport.aspx?SLanguage=en-us I don't know what would happen if you plug the 3.73Ghz into the P5P800. Your processor is FSB1066, and that would be a 33% overclock for the 865PE Northbridge. The processor may start at FSB400 (it really depends on what the clockgen chip does with a 000 BSEL code) and you might have to use the CPU clock adjustment, to try to get closer to FSB1066. The thing is, boards using the 865PE see video artifacts on their AGP video card when running a high overclock. In order to run your new processor at its rated speed, you would be running the Northbridge at 266MHz instead of 200MHz. You can see a variety of experiences here, with the 865PE Northbridge, and various RAM ratios. http://www.abxzone.com/forums/showthread.php?t=62275&highlight=artifact If you use the CPU search in the middle of the Asus CPUSupport web page, it returns this for Pentium 4 3.73GHz Extreme Edition FSB1066 LGA775. As far as I know, these are all PCI Express motherboards. One of these boards would be a better for use with your FSB1066 processor. Motherboard Since PCB Since BIOS P5AD2-E Deluxe ALL 0302 P5AD2-E Premium ALL 1005 P5LD2 ALL ALL P5LD2 Deluxe ALL ALL P5LD2-V ALL 0304 P5LD2-VM ALL 0128 P5ND2-SLI ALL ALL P5ND2-SLI Deluxe ALL ALL P5WD2 ALL ALL P5WD2 Premium ALL ALL The P5P800 is listed as working with a 3.4GHz Extreme Edition. That has a family code of 0F25, and the chip is a Gallatin 0.13u with 2MB cache. Stepping M0. And FSB800. http://processorfinder.intel.com/scripts/details.asp?sSpec=SL7RR This is your processor. It has family code 0F43. It is 90nm, so it is not a Gallatin. Tomshardware lists is as Prescott. It has a multiplier of 14X (3.73/0.266=14) and if run at FSB800, would look like a 2.8GHz Prescott with 2MB L3 cache. http://processorfinder.intel.com/scripts/details.asp?sSpec=SL7Z4 Here is an article benchmarking your new processor. http://www.behardware.com/articles/551-3/intel-pentium-4-660-and-ee-3-73-ghz.html The easiest way to use your new processor, is to use one of the motherboards in the list above. These motherboards use PCI Express video cards, and I think they all use DDR2 memory. In order to reuse your AGP 8X video card, you really need a different processor to work with. This will require some careful thought on your part, so that you will not end up with incompatible hardware. PCI Express and DDR2 are the current Intel technologies, and selecting the most capable Intel board will best prepare you for whatever the future offers. You could, of course, sell your nice processor on Ebay, and then buy a set of hardware you are happy with. If your processor happened to be an ES (Engineering sample, with unlocked multiplier), then there would be fewer issues to being able to use the processor. Paul

So far as I understood is the i865PE not capable of doing 1066MHz FSB. But, I stumbled upon this.... http://www.asus.com.tw/products4.aspx?l1=3&l2=11&l3=26&model=629&modelme nu=1 there it reads: The P5P800 SE supports the latest Pentium 4 CPU from Intel in LGA775 package. With 1066/ 800/ 533MHz FSB, Hyper-Threading Technology and core-speeds up to 3.8GHz. Hmmm.... If this is really true what I found, then we have no problems.... The GfX is already bought. Itýs a GeForce Ultra 6800 AGP8X (watercooled). I am pretty sure he wonýt give it up. > I don't know what would happen if you plug the 3.73Ghz into the > P5P800.

Yeah, it (iEE) could work with 200MHz, at least. I am sure, that it would be also a fast machine. > The thing is, boards using the 865PE see video artifacts on their > AGP video card when running a high overclock.

I tried to suggest him a Pentium M system. Best Regards, Daniel Mandic

And the claims on that web page are pretty amazing. Running a dual core on a 865PE ? I went looking for a downloadable user manual, but cannot find one in the usual places. I hope the board really exists. > > The thing is, boards using the 865PE see video artifacts on their > > AGP video card when running a high overclock.

The thing is, if the 865PE is run with 266MHz FSB, the video output from the AGP video card develops artifacts, dots are visible that should not be there. This newly designed board had better have a fix for that problem, or no user of a FSB1066 processor is going to be very happy. And the 865PE chip will not be "new and improved", because Intel will be in the process of discontinuing production at some point. Before you buy the board, see if you can find a review of the P5P800 SE. I'm not sure this board is shipping yet. > > Best Regards, > > Daniel Mandic How in the world did you find that web page in the first place ? Paul

You said well. There is no P5P800SE listed to buy :-) But I found an Asrock 775i65PE which seems to be fit, supporting the EE up to 3.8GHZ. Itýs also a i865PH Chipset. What would you say? Slightly OT, so far I know is Asrock the smaller ASUS, or so.... Best Regards, Daniel Mandic |
