    Exclamation Building a new system with EP45-UD3R

    I bought the EP45-UD3R, 2X2GB G.Skill 1066 memory, Antec case and a decent Zalman HSF, etc. before Christmas to build my first system. (I already had a XFX 8800GT 512, 600 watt PS and Pentium D820). My previous system 'died' and I was hoping to upgrade around the (admittedly dated) CPU. Boot drive was okay.

    I put everything together and the first time it worked like a champ. Updated my Windows activation key and some drivers, wireless was working and I was off running load tests. While I was in ST6 (didn't change anything) the system hung. After that, I couldn't reliably get into BIOS much less get Windows running. (Granted, I understand it's a crapshoot to be able boot from a previous chipset's OS build.) BTW BIOS Rev level was F4

    I stripped the mobo down to 1 stick, CPU, GPU and PS. I can get into BIOS painfully (lots of Ctrl-Alt-Dels) but it always hangs somewhere. Tried innumerable combinations and found nothing that stay up. I RMA'ed the Mobo to NewEgg, figuring I had a bad board.

    Just started playing with the new board yesterday. I'm getting pretty much the same results. Okay, I don't care anymore about booting with my XP build. I can re-build the OS it but I still have issues with stability. I tried my old memory (667) and it's a little better but still not good enough. I hooked up a CD/DVD and I can (occasionally) get it to begin to boot off the XP CD, but it always hangs.

    I've adjusted the timing and voltage for the G.Skill memory to match their specs but nothing leads to consistent results. Okay, well maybe one thing is consistent; if I clear CMOS I can get back into the BIOS. Loading either Fail Safe or Default doesn't seem to make a difference. But if I adjust voltage / timing it hangs and we're back at the beginning.

    Could my D820 be the problem ? (It is supported on the UD3R with Rev 4) I'm not averse to dropping $165 (plus shipping!) for the Wolfdale but I don't want to collect HW that I can't get to work together

    I also have the ATX 4 -> ATX 12V 2x4 adaptor for Mobo power because my PS doesn't have a native ATX 12V 2x4

    I've seen too many posts on NewEgg extolling the virtues of this Mobo so I must be doing something wrong here vs. a design flaw. (And I get paid to do IT )

    Any Help Please!!

    Have you tried it without the ATX 12V adapter?

    Your setup should run fine with just the 4-pin — 8-pin is only necessary for highly loaded systems and you just might be under-volting something by combining both on one rail (just a thought.)

    Aside from that, I'd be carefully checking the voltages from the PSU — 2 mobo's showing the same fault is straining the friendship a bit.

    As a matter of fact, I did try it without the adapter and got the same results.

    Other ideas?

    My new system (not in daily use yet awaiting a couple of items) has the same board and a somewhat more expensive 4GB G-Skill RAM kit, but an 8500 Wolfdale (stock cooler), 8800GTS and OCZ 700W PSU (which has the 8-pin 12V plug), also 7 HD's, 2 opticals and floppy.

    It has somewhere about 100 hours on it so far with no obvious problems worked fine from the get-go apart from setting FSB @ 266 instead of 333, which I already expected and fixed in a moment.

    You mention you've used ST6 did either of the boards work OK before that?

    If it mis-detected the CPU and puished it too hard, that might well be the problem.

    I tried it (ST6) on mine and took it off again it was doing odd things with voltages even on a setup that it should have known all about and had pushed the E8500 lots higher than I liked, especially with the stock fan (can't recall exactly what, but I shuddered and dropped it back real quick E8500's are about $US220 here...)

    Can you test the D820 in a different board? (maybe it was what died (or got red in the face when something else died) in your old setup?)

    The spec's for your PSU show 29A total (regard it as maybe 26A when calculating loading never trust the wholesaler's spec...) on +12V, which ought to be about enough, but I'd prefer to see a few more.

    Couple of things ....

    Out of the box(es) it worked fine with both sticks. Perhaps in my efforts I changed something in the BIOS and did not correctly / completely clear it ... I tried one stick and I could get nothing - just kept re-booting. Swapped sticks, cleared CMOS (per the the post) and now it seems 'better'. I can consistently get into the BIOS but it still often 'hangs' while in there.

    A template for the Pentium 5 D820 with the G.Skill memory : G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) would really be helpful. I'm using stock setting except for DRAM voltage and timing. I've tried to leech off other posts but I don't have all the options the Wolfdale CPUS have.

    I'll keep looking in case Lsdmeasap doesn't respond

    make sure your bios is F4 to order work with older Pentium D 820.

    I'd still like to see you test the CPU in something else — all manner of things can happen when a mobo dies, and it WAS in your old system.

    That both boards worked initially out of the box suggests a problem with something else, and I'd always suspect parts that were in a failed system.

    I assume you've tried looser timings on the new RAM?

    Also BIOS F5 is now official — might make a difference.

    No I hadn't tried looser timing on the RAM. Took the stick to 7-7-7-21 and went right to boot screen. Since I didn't have a drive attached, it stopped there, but that's okay. This is progress. I'll attach a drive (DVD, former boot device, etc.) and see where I go.

    Is it worth my time messing with this D820 vs. upgrading to a Wolfdale?

    Looks like it might just be that the processor can't keep up with the standard timings for 1066 — persevere with it and see how you go.

    I think 800 was considered flying pretty low when it came out.

    As to whether the expense of the Wolfdale is worth your while, I guess that's up to you...
