    Default Picked up another UD3P and an E8400

    Was getting so sick of my buggy DFI RDX200 that I used as my work computer, so decided to get rid of it and build another ud3p and an E8400. I was pleasantly surprised to get a lower vid cpu than my other one. This one has a vid of 1.175v while my other one is 1.20v. With my other box, I only wanted to clock it to 4ghz with the lowest voltage across the board, but with this one I just might have a better cpu.

    I orginally had a 700W OCZ gameXtreme psu but when I assembled the whole computer, the damn thing would not boot up. No phase LED lights at all. That was weird. Figured it might be a short somewhere, so I pulled the board out of the case and left it on a static sheet and pulled off everything but the cpu, hsf, and 1 stick of memory. Fired it up and again no phase LED lights. Grabbed my spare Fortron 1010w that I had lying around and plugged it in and it fired right up. Weird..... the OCZ psu has four 18A 12v rails and it was built by Fortron, while the Fortron Everest 1010w has four 20A 12v rails. I guess 18A 12v rails was not enough to power the e8400 even at stock speeds. The psu is only about 2+- years old but just didn't expect it to falter with the new build. So I reassembled the computer with the larger psu and set everything to stock speeds for now. Running prime95 blend for 24hrs just to see make sure everything is working.

    This is just my work computer so that is why I don't need a powerful video card, but I may stretch the legs on this cpu just to see how far she can run. Have high hopes for this low vid cpu.

    Since I am only using 2x2gb on this board, I think my goal for this setup is going to be 500x9=4.5ghz. We will see wether the oc gods will let it be so.

    I am more curious as to how these Buffalo firestyx will perform though. We will see.

    That OCZ unit should power the system fine. I'm using a OCZ SilentxStream 400W in this rig atm, until I get my BFG replaced. It's running my overclock fine and has 12V1 = 17A and 12V2 = 14A.

    Either the OCZ PSU you have is dead, or it's got compatability issues with the UD3P.

    Yeah, like I said, it was weird, because I wouldn't have figured that 18A wouldn't be enough. That psu was working perfectly fine with the RDX200 and an opteron 148, and 2x1 gb of memory. All other computer parts were the same. I even plugged the OCZ psu into a psu tester and it checked out ok. Werd. I might plug it on an open bench with the old mobo and plug a bigger video card in it to see how it fairs. Will double check the voltage rails with the dmm.

    Maybe compatiblity issue with the UD3P.

    Truth is I am not a big fan of multi 12v rail psu's anyway. I prefer one honkin big 12v rail (and the other 3.3, 5v, etc rails). If some of the 12v rails are not utilized, it just gets wasted, ie. pci-e plugs.

    It depends on how the OCP circuitry is organised. For example, my BFG can kick out 65A max, but has a limit of 2*22A and 2*36A. this means that if not all ampage is being drawn from one rail, it can be used elsewhere, within reason. Some 2 rail+ PSU's have absolute values, and all rails added together = the max Ampage. On this type of PSU, it is indeed wasted power.

    One massive 12V rail is the best way to go, followed by "Virtual rails" and lastly independant rails.

    I have a EP45-UD3p + E8400 and it runs fine on my Rosewill 500W PSU. That is in conjunction with a 900GT 1GB overclocked, 8Gb RAM, 1 250GB Seatgate HDD, and 2 500GB WD Greens, oh and an LG DVD writer.

    I hope you get her running, though. I thoroughly enjoy this particular combo.

    As it says, I didn't stress it, yet. So consider it a starting point.

    I just noticed somebody with an oc'ed Q9550 mated with a UD3P using only a 600W GameXtreme, so I guess it is looking like that my OCZ psu might be borked. I will test that psu out more thoroughly when I have time. The good thing is that I think I might still have a year left in the 3yr OCz warranty. I just have to see if I can dig up my receipt.

    Have about 3hrs left for my 24hr blend prime test at stock speeds then I will jump to what I have used for my 445x9 settings on my other ud3p box, and then will move to 500x8.5, and then to 500x9. With this low vid chip, I am hopeful that the end game is achievable.

    Well phase 1 is going at 6hrs with prime blend with surprisingly low voltages ..... vcore at only 1.2375v. CpuZ reads 1.168v with load vdroop. Once 24hrs stable, will move to phase 2.

    Very nice so far! I can see you getting 4.3GHz + on this one. Cooling is well under control, so it's possible. What are temps like so far?

    Have you considered giving Win 7 a go? I've been using it as my primary OS since the public beta and it's never let me down once. Drivers thet work with Vista 64 are rock solid on 7. You may have to change compatability settings to Vista SP1 to get some to install, but that;s the setup routine's fault, not the driver. The RC doesn't expire till March 20010 either, which is great.
