Good to hear you got your issues sorted out.

Thanks~ :up:

Update: My fix didnt work, it's stable running Prime95 and decoding x264 720p overnight.. but after about 3hours Xvid playback still locks the system, I'm about to give up and assume it's some driver problem

Make sure your FSB VTT voltage is at 1.5, anything lower can be unstable, even if it passes prime95.......set it to 1.5v, this is a key voltage for this board and quads.

Yeah, that's what i've had it set to. Tonight I tweaked each voltage up and down individually once I found a good baseline, still no dice. I ended up 9x355 for 3.2ghz, oh well.. I might try again once P31 hits. :(

The P30 bios has been really good to me. It enabled me to boot up at 3.6 (400 FSB). I also just did the vdrop mod to my board today as well, while dusting out the radiator. So far it's all good! I can use a much lower vcore now! I ended up using a circuit writer pen that I got from Radioshack a couple of years ago when the nForce 4 from DFI was the rage (used it for the SLI mod on Ultra-D).

Thanks for the pictures! It really helped!

Be careful using a circuit pen for this mod as the goal is to lower the resistance, not completely remove it. that's why people suggest experimenting with a few light pencil strokes at a time until you get the desired result.

Hmm, i realy want to know too, what is the stock resistance without the mod and after mod is done to be shure, that its working best for no vdrop at all? :) Im going to mod my board too, and if conductive ink is posible to use, then I can do it too :D

the picture says 100 kOhms but I have not tested it myself, just a few times over with the pencil and my droop was fixed. For reasons behind why overdoing it is bad I dont have any, i'm just echoing what ive seen written about the mod before ;)

Hmm, yes, but I really want to be sure, that if I change xx ohm to yy then there is best result for more solid voltage, best would be if there is a little bit more voltage at full load than idle or the same ;) And maybe there is a bad side effect if I change resistance to wrong value.

Maybe author of his vdrop mod or some one else can say exact measurements what they set? And I think you should always use multimeter when doing some hard mods :yepp:

Agreed that information would be incredibly useful.
Anyone care to oblige?

Seems just fine to me. The pen doesn't throw down a huge blob, which is fine. It's like a thin line, which is perfect. The whole goal was to remove to the vdrop problem, which it did. You shouldn't want any drop on it anyway. You should definitely get what you set in BIOS. 1.5 = 1.5 :)
I hope you aren't confusing which mod I did. I just did the two red points that I saw, and nothing else. Blue ones were left alone, as they were an alternative. And the other red area to "ground" was to reduce vcore vdroop under load if I understood it correctly.

Anyway, as far as I'm concerned - it was successful.

I'm just stating a heads up on the pen, there is a reason people want to know the exact resistance to aim for.. but I agree, if it works it works :D

with only the "red" mod mine has .01 drop from bios setting idle, full load it is 1:1 with bios setting.

I just build my new rig and here's my results so far. Ambient temps are pretty bad during this quick stability test so im gonna wait for it to cool down till I prime, 81f right now. Anyone ever seen this batch? I search a few places including google and didn't find any info on it (L725A883).

i hope a bios update can fix my issues...

finally picked up a quad when they had them in stock locally so i could pick week/batch

Q6600 G0 L723A 1.2375 VID
Evga 680i A1

bios settings for 450fsb x8 3600mhz

cpu: 1.45
cpu fsb: 1.4
ram: 2.15
spp: 1.35
mcp: 1.5
ht: 1.35

PC2-6400 Elpidia IC
900mhz 1:1 @4-3-3-15-4-18-6-10

in windows idle voltage, as reported by cpuz and everest, is 1.408/1.4v respectively. at load cpuz/everest reports 1.368/1.37.
450fsb is close to max for this cpu or chipset

bios settings for 411fsb x9 3700mhz

cpu: 1.47

PC2-6400 Elpidia IC
811mhz 1:1 @4-3-3-10-4-13-6-10

haven't tried higher as it's 28c~ in my apartment and cores reaching around 67c at prime :(

I haven't checked this thread in a while, sorry! lol

I have a week 23 g0 Q6600

1.525vcore for 3.8ghz daily use
2.150v for memory
1.55v for nb
1.4 for sb
1.55 for nb-sb

I'm not at home, but if I recall my settings correctly, I haven't changed it since I got stable at 3.8ghz for the last couple weeks.

Is there any word on how well the 680i LT boards from EVGA work? I know DFI used the 680i LT because it was supposed to be 'better at overclocking'. I'm trying to decide between an EVGA A1 board (either 680i or LT) and DFI's board.

I already have a couple solid G0 quads, I'd just like to use my twin 7900 GTX cards in my Windows/gaming box and my Abit IP35-Pro and 7300GT in my Linux machine.

Nice thread, by the way.

Has anyone experienced any problems with the P30 bios ? People have been reporting numerous problems that involve the updated bios kiling their boards. I personally had to RMA my evga 680i Ai board because I would the " -- " post code when dropping the multiplier on my Q6600 to 8 and incresing the FSB to 450 and above. If I increased the FSB over 1600 on the 9x multi, I would be able to boot to windows but it wouldnt be possible to do anything as it would reboot.

I did do the pencil mod, but no matter what amount of Vcore I gave it after 3.5ghz, it was never stable to do anything. As for the FSB holes I experienced, jumping over them was never enough as I couldnt do anything but boot into windows. The highest I got my chip (L26A) was to 3.93hz, long enough to take a screen shot. So im not sure if it was the bios update or the pencil mod that began giving me the " --" post code.

On a side note, I never ran into any of these things when dropping the multiplier and increasing the FSB on my E6700 :shrug: . My board was capable of reaching a FSB of 1960 though.

I have both the DFI & Evga A1. I even tried the T1. The DFI is much faster than any other 680i board out there. I think only the Asus Striker is faster but it doesn't do well with quads. That said, the DFI is the most difficult board of any to get a Quad core finally up and clocking once u get past 3 Ghz or so. I'd pick the Evga if you not looking to bench competively. The pencil vdroop mod makes this board the best 680i for stability & ease of setup for quads.

I had mine running Orthos for over 5hours before my computer restarted itself

my settings were

400*9
1.41625 CPU
1.5 FSB
1.55 SPP
1.60 MCP
1.55 HT

temps reached 70,70,66,66 and never went any higher. it just randomly restarted after about 5.5hrs.

im on the P30 BIOS also. my CPU is a L723A batch.

I don't bench and I'd rather not spend weeks trying to get the board working properly. I'll pick up an A1 680i, hopefully I'll get one that lasts. I'm glad I have a second board to fall back on.

Yesterday started to test my new Q6600 G0 L720B and my 680i A1 board, had problems to post over 400 FSB, but then I lowered voltages a bit, set HT at 4x not 3x I had before and now I coud do even 475 FSB in BIOS, thats insane I think on 680i board :clap:

Will test more, I hope my board can do 4 at least 440 - 450 FSB for 24/7 or even more :) Aiming for 3.8Ghz, now runing it at 400 x 9 at 1.45v in BIOS, lowest voltage I saw under prime load was 1.360v :shocked: :shrug: Hope vdrop mod will help a lot :yepp:
