Jon...….you should have seen my hands shaking when I did a vdroop hardmod on a then brand new GA-990FXA-UD5 Rev. 1 board. I had a lot of money invested in that board but it was one of those bad Giga models. Scottie coached me thru that one too Jon. A super small SMD had to be swapped out. It turned out real well and was one of my favorite boards after that. I still have it to this day. My eyes were crossed during the whole operation. LOL Edit: by the way, nice job Jon. Haha. Hands shaking was on my first couple soldered de-lids. I know exactly the feeling. I am comfortable with soldering, I do it quite often. Just not in the same type of application, most of the time it's a repair of a broken wire. So why did the 990FXA board need the vdroop mod? The LLC did not work? The board has no LLC Jon. And the vdroop was sooooo bad it went right into the basement. It would cause instability at stock settings. And then it would overvolt like mad at the same time. Voltage was all over the place on that board. Stupid design. And Giga support really sucked and I didn't want to deal with them so rather than RMA the board I decided to do a vdroop hard mod. The UD7 also had a similar hard mod for it for the exact same problem. I had one of those too and sent it back. It sucked. I was having nothing but bad experiences with 990 boards back then. Then I discovered Asus and never turned back. Edit: Steve. B(Sin0822) Turned me on to that mod. Edit2: This was on the Rev. 1 Boards. They kinda sorta fixed it after that, but the Giga UEFI bios sucks.

Interesting wondering if the UD7 board is the same mod.?

I was able to post 1 cpu and run it around a bit. I wanted to swap the chip out, was a mistake. SHould have left it alone. I wound up junking the board though. Got it free from a reviewer, so easy come easy go. I* don't recall the ins and outs of the bios, but could swear it had LLC. Anyhow, thanks for the info, Zila1. Never knew.

The Vdroop on both boards was so bad that you had to overvolt like mad to try and compensate for the massive droop. I had to set a cpu voltage of 1.65V to compensate for vdroop of over 0.144. I don't have info on the procedure and placement of the resistor that needs replacing on the UD7 Pete. The pics are all gone on the internet. www.overclock.net/forum/11-amd-motherboards/1086462-990fxa-ud7-review-analysis-ripple-testing-benchmarks.htmlYou don't need this mod on boards above Rev. 1.0. They have LLC. I remember Scottie and I going back and forth quite a bit over my UD5 back in the day. We couldn't believe how far I had to over volt my board just to get a stable stock running board. (And Giga telling me it was perfectly fine) Then we put our heads together and I did the resistor hard mod. **Edit: Looking back on my notes I was seeing a vdroop of .300 at times. Unbelievable Instability.

I didn't know the value of the stock factory resistor but the replacement one is 100K ohm.

Ah, if we knew the resistance of the original, we could just add another on top in parallel to bring the other one up. Touch easier adding another than replacing that one.

Got Burnee on the table Bones . Will spend the rest of the comp on sA platform.

Got Burnee on the table Bones . Will spend the rest of the comp on sA platform. I believe with the right chip and setup he'll do well for you. That's the one socket I haven't tackled yet, will see if I can get around to it after I finish up with the others.

I think I'm having a water block mounting issue, OR the darn thing doesn't like the colder temps at post. It turns on 1 - 1.5 seconds and shuts right off. If the waterblock is mounted kinda kaddi wompus, I get 9.0 and then reset CF which is fine. Cause when I adjust the block a touch, it'll attempt post and shut off. lol. She's fighting me this evening. Gotta get to bed though. Tomorrow is a new day..... For work. Tried a 1600, 2400 and now a 2500.... All seem to do the same deal as above. Think on it, let me know what you think. Oh and don't forget to vote.

My NF7S will boot with the CPU at -150 I wouldnt think it would be the colder temps but if its an AN7 I dont know.

AN7 has CBB. At least mine does. Have to be above 10c to boot. Ultra B has the same problem. Set it up on air first Jon. Make sure everything is good.

Haven't got 462 (Abit all I have to works) out yet but have had odd experiences where I've let the chiller get cold before putting power the CPU/MB and wouldn't post, yet the next day without changes booting the CPU and waiting for the chiller to catch up no problems, so I'm along with Scott here. Kinda thinking how the board is insulated at present.

Had it setup last night and almost didn't try to post it.... But that benching itch came on and had top try and fire it up. Why do I do this to myself..... But yea, I think my water delta is a couple of C too low. It'll fire up, I have confidence. It's a great board, did just fine last time I set it up. It did give me a bit of a similar issue, but the mounting arrangement is the same. I think my issue is being using only 2 mounting screws instead of 4. The other 2 are on my Intel setup because I don't have a Cpu cooler for it. So I made an AMD cooler do the trick with one of my modified brackets. It does well.... but I need the screws now lol. I should get more of them though, next time I'm at the HW store for sure.

First time I've been over 3.5v on the RAM (3.7) now to work on efficiency (I'm pretty happy so far). Still a day or two off. The other platforms using what I'm use to so shouldn't take to long. Nice RAM what can do in Superpi 32M?

Nice RAM what can do in Superpi 32M? I really don't know, the DFI wouldn't post (VGA problem I hope) so switched to a Asus board lacking voltage adjustment. As for SP I generally suck at it.

Spending way too much time on Socket A here with the intention of testing a few XP 2500+ Barton CPUs I haven't run before. Switching from a AQXEA 0330XPMW to a PQZFA 0349MPMW resulted in the siren once the power button was engaged. OK, fine. So I cleared the CMOS and it just won't go past 9.0. post code (which is the end of the Power On sequence ending with 9.0. "Complete uGuru initial process" according to the book). Warm reset results in F0 (button reset). I'm guessing this particular CPU is a dud.

AN7 board?
Be sure the CMOS jumper is on pins 2 and 3, not 1 and 2 like would be to hold settings on other boards.
If so it will give the 9.0 code - I found that out the hard way long ago.

Yeah, AN7 board. IT has been working as expected with the CCMOS1 jumper set to the normal (default) position with pins 1 and 2 bridged. I just tried it the other way and it's the same result. Maybe I'll try the NF7-S v2.0 tomorrow with this CPU but I think it might be stuffed (the CPU, that is)

These days when I plan to bench, suddenly have interview for some job and no time to bench. Now fight with Wprime and 939 but is very annoying

I got no VGAs for S462 tested two cards on the 754 setup both with problems. Would of had to change the block out and I've some AM4s I really want to try.

Guys, it looks like this one is over with d0minat0r being the overall winner! Didn't get to do as much as I would have liked myself but at least I had a crack at a few. Was a pleasure coming up with the concept, planning of and implementing the comp itself so anyojne that would want could participate. I don't know who's doing the next comp but won't be me.....
Maybe what I've done here though could be food for thought about a way to setup a really good comp for all.
