Does anybody know Vdroop mod to A1 revision?

nice work Gar! thats a nice b3 you have there!

Thanks bro!! wish it would do 3.6ghz but ill settle for 3.5 :] cant have the cake and eat it to.

[skndvr]

Ill take that anyday. and on air? geez, how do you like the 120? got rid of the zalman, hey?

Sorry guys looks like the starter of the thread has to remove himself from the festivities due to Mobo troubles yet again! I am also switching boards due to the frequency of the RMA involvement with this board as this will be number 3 in three months and I cannot be bothered with that

[NKD]

welcome to club, 6 evga board i went through in 6 months, when someone tells me this is a trouble free board i tell them good luck and i hope it stays that way,

That crazy, since I'm still running perfectly stable with my current mobo, and been running it since November when it came out Seems like a real hit or miss with these, both in overclocking and manufacturing quality...

GAR - Nice overclock Do you have any CoreTemp screenies? Speedfan reports 15c too low by default (unless you fixed that already)

QX6700 ES @ 3.6ghz 1.53vcore - 12hr p95 stable



Failed prime after 7hrs with 1.45 so upped it to 1.53 to be sure. Passed now so I can lower the vcore back down a little and test again. Not bad vdroop either - 0.032. Vdrop however is worse than the dual cores - 0.075

Load



Idle



Not a G0 nor a 6600 but hey for the price I paid I can't complain - not bad for a B3 chip (L632A865)

One thing I have noticed though is that when I get a failed overclock the board goes into '--' mode and at first I was having to reset the cmos and enter all the settings again. I have since just left the pc unplugged for around 2 mins and I can then get into bios without having to reset cmos to get it to boot.

I am also having power issues with the Zeus 750w. Whenever I power off and power back on again the motherboard reacts as though there is a short (there is none) and I again have to wait a minute with it unplugged until it will power back up.

hey man...sorry to hear of your troubles with your mobo, whats going on now?
stiill glad you started this thread, it been helpful to us 680i/quad owners.

after messing with various overclocks, and never being one to have to much patience for waiting i always jump up into higher oc's right away.

my clocks were not stable...so i am now working my way up slowly.
hard to tell if it my cpu, ram or mobo....
i was thinking about the gigabyte dq6...but for now i will stay put with what i have for awhile, and see what Q4 brings us...newer things are right around the corner...

Got my Q6600 G0 to 3.2 prime stable. My board seems to like being at 1600fsb (huge FSB holes below that) ... the chip isn't quite ready for that at 9x though ... boots, and actually works fine, but can't prime past 20 minutes or so ... dropped to an 8x multiplier for 3.2, primed all night without breaking a sweat.

My original goal was 3.2, so I guess I'll stick around here for a while. Wish I could do it at 9x but that puts me in the rather large FSB dead zone. Plus side is my memory benchmarks nicer with the higher FSB.

Current voltages:

CPU - 1.4v (manual)
Memory - 2.1v (manual)
FSB - 1.4v (manual)

HT(SPP-MCP) - 1.2v (auto)
PCI-E - 1.4v (auto)
nForce - 1.5v (auto)
AUX - 1.5v (auto)

[GAR]

OK, little issue im running into here, im using this setup, but sometimes my multiplier reverts back to 6x, here are what my volts are at

cpu = 1.57
vtt = 1.5
spp = 1.45
mcp = 1.6
HT = 1.5

all of the cpu features have been disabled, spread spectrum, speed step, vanderpool and etcc.... eevrything is disabled, i am running this setup here, it is prime stable PC is stable but sometimes when i start up the pc it just reverts to 6x multi instead of the 8 i have choosen in the bios?????

[nullptr]

I've had the 6x issue a few times myself, a reboot has always fixed it (no settings changed).

isnt the pencil mod in the mod section?cant remember.

Do you have your USB headers connected??? Try to remove them and see if your problem persists. I found that was my problem. Odd but true.

Also try lowering your SPP and MCP linkage to 4x. Seems to really help me in my 1600 QDR and up OC's.

I am running 3.6Ghz 1.37Vcore load(DMM) and 4Gb (GMH) @1066 5-5-5-11 and loads of 47-50c. Loving the idle temps of 28-32c.

Cant wait for penryn

The 120 is awsome bro, the zalman just wasnt getting the job done, the ULTRA 120 extreme is awsome, as long as you do the washer mod, or replace the screws.

Tried removing the USB headers but it didn't work for me. I also get the '--' from time to time, if I tap the psu then it kicks it into action so it looks like its a PSU problem . Got 4gb stable @3.6ghz though by raising the SPP a couple of notches (1.5) but the ram is only at stock for now.

vdroop mod it then.

Anyone tried this? Possible with a pencil? I dont trust my soldering skills.

[Brother Esau]

Ya USB on this board is aweful mine just decided to stop working the other day that is I mean all 4 of them blasted Foxcon with their sub par Sh*t!

I just tried that mod but with #2 pencil. It works outstanding. 1.50v bios, 1.50v windows and 1.51v loaded small fft!!!!!

Just did the vdroop mod, took 1 minute, awsome, 1.47 bios, 1.47 windows, 1.48 load, nice!!!!!!!!! everyone should do this mod now!!!!!!!!!!

I'll be damned. Gonna try this right now

That is so weird. I had the exact same problem with the ST75ZF/680i combo, but different causes. Too weird....

And about your ram I would try lowering your chipset links to 4x and run linked 4:3 (I think) and you will get 1066Mhz. I had to run 1.45 MCH and 2.05Vdimm to get stable. It wsa wierd that I actually had to lower my Vdimm and MCH voltages to get them to run stable.

If you need a list of my settings PM me and I will get them for you

Edit: Did the drop mod and works flawlessly. The thing i hated the most about this board is finally gone!!! Yay!!!!

That would be very much appreciated if you don't mind m8.

As for the drop mod - Never done a volt mod so if you could guide me with kid gloves...

Will any pencil do, say a HB? I presume it needs to be a graphite pencil?
How many passes?
Lightly or hard?
Does it need any soldering?

Managed to do a 4gig PI run but its far from being p95 stable :

[GAR]

Just pencil the 3 places that are shown in the picture, a #2 pencil will do just fine, worked fine for me.

[turtletrax]

You shouldnt need the Vcore mod unless you are using Phase or L2N/DICE, correct? The board is capable of giving 1.7v+ to the core, so you would need extreme cooling for more.
