The Much Needed EVGA 680i A1 Q6600 O.C thread

[Hachi_Roku]

there were a few fsb holes for me with Q6600 G0, A1 and P30 after 400fsb. also i cannot get the quad stable at all with 1.5v cpu fsb while 1.4v works until 456 fsb where i hit another wall either cpu or mobo fsb limited. also sometimes the board changed the multi to 6x at POST, usually on a bsod.

i would try +5fsb or so at a low multi to see if it's just a fsb hole.

@Matt C try 1.4v fsb might be problem as it was with me.

edit: or try 4x HT link on SPP/MCP

vcore: 1.3000
fsb: 1.5
SPP: 1.55
MCP: 1.65
HT: 1.55

You need to download Coretemp 0.95.4. Your temps are al low by 15 degrees !

no they are right. i just have the speedfan temps bumped up 15* to make them both the same.

OK, so i was watching a movie with media player and my computer just restarted by itself, but my pc is totaly stable, i can play games for hours, and prime stable, passes memtest as well with no issues, i remember someone else saying they had an issue with this, anyone? im using vista 32 bit.

OK, so i could even encode a movie with nero and it goes through it just fine........this is annoying.

Oh ok. I just didn't want you to fry your cpu. Just looking out for you.

I had the problem with xvid playback freezing, still had it with my RMA board, raising HT to 1.45v fixed it for me (at least for now)

For the past couple of days I'm trying to get my new Q6600 STABLE AT 3.6 Ghz but without succses. It will run Prime 95 25.4 for 2 hours(then I stop it manually), and remain stable for playing games,video encoding..., basicaly anything. After couple of hours and sometimes even the next day computer locks up while on desktop,doing nothing or sometimes while playing the game.

First I've tried with higher VCore but it's all the same from 1.375 to 1.45. Then I moved on to adjust the other voltages and tried different voltage combinations for SPP, MCP, FSB and HT, and noticed that they are best if left at AUTO(which is completly different from my previous Core2Duo E4300 that needed these voltages set manually for decent overclock). If I set these voltages at anything else then AUTO computer restarts or fails Prime in matter of minutes. Memory is out of question because it's completly stable(tested with Memtest 86+).Also, tried x8 multi with 450 FSB and it wouldn't even boot.

Does anybody have any suggestions on how to resolve this? All help is very much appreciated.

[icon57]

if you want to boot at 450 x 8
i def would set volts manually, and not on auto!
you need to read through this thread for volt settings...i can boot at 450 x 8, but i see no dif in running 400 x 9

I'm not sure if you actually have a G0 or not, since you copy and pasted your message in two threads, and it looked like you were spamming. Sooo, I'll assume you don't. Even though that thread says G0 people can easily wander into the wrong place...

3.6 might be tricky if you are using a B3...
For 3.6, which I wasn't very comfortable with, it needed 1.5475 vcore, and 1.55v for the MCP <-> SPP, and 1.5v FSB. It was stable in the tasks I did, except for long duration heavy load.

My B3 did 3.3 easily. Here were my settings (with vdrop mod).
Vcore: 1.45v
VFSB: Auto/1.4v (1.5v set manually in here works great too)
Memory: 2.1v
SPP: Auto
MCP: Auto
MCP-SPP: 1.45v

The vdrop mod is very important on the 680i board. Since it drops pretty badly. These worked VERY well for 3.3. It did a full 24/7 Prime Small FFT, and ran WCG just fine as well.

I also have a G0 that I got yesterday, it's an L727A. It's doing 3.6 @ 1.45...still doing small FFT's right now. Going on 7 hours. Will do a full 24 though!

The only difference now is that I can do 3.6 with my vFSB @ 1.5v. And it's looking good!

And two hours prime is NOTHING. Make sure you do small FFT's at least..

You also need to keep in mind, NOT every chip is a freaking winner. And don't be lame and return it because it didn't clock the way you wanted it to. Testing to find your max clocks is better, and then once you do, lower it a bit until it's stable 24/7.

QFT. One guy in this thread also left some voltages on Auto, and that works just fine also. I believe he left his MCP-SPP auto, as well as the actual volts for MCP/SPP. You absolutely don't need to shove so many volts at it to get it to run STABLE. As long as you do the VDrop mod, you are a-okay! That's what matters most when you overclock the quad.

Thanks for replying Reinvented and icon57. I posted in G0 OC thread as well because that thread gets visited much more frequently.
Anyway it is G0, batch 720B080. I can do 3.3 Ghz with really low voltages:

Vcore: 1.325v
VFSB: Auto/1.4v
Memory: 2.0v
SPP: Auto/1.4
MCP: Auto/1.5
MCP-SPP: Auto/1.2v

It's all very weird because I needed to set all those voltages at 1.5v for E4300 in order to get it stable at 3.3 Ghz. I did VDrop mod before this Q6600 was instaled.
I follow this and G0 OC thread from beginning and as far as I can see different people say different things,regarding these voltages.
I remember that guy with all the voltages at auto except for Vcore and Mem (NoSoMo I think) ,and also there are those that have set their voltages to something like:
1.55v for SPP
1.65v for MCP
1.55v for SPP-MCP
1.5v for VFSB

I have tried both settings and many in between,but everything else except for AUTO fails Prime pretty quickly.AUTO settings will give me couple of hours to a day of stability.
Temps shouldn't be a problem,case is ventilated properly and TRU 120 EX is doing a good job for cooling the CPU.

Reinvented,can you please give me voltages you're Priming at ,at the moment?Thanks again

[yasoumalaka]

Look at my sig!!!(((sry have a se not a1))) I had the board for a couple of days. Thank god for Fry's being in town. Only thing I can add to this thread is that I messed with every setting trying to get 2.7Ghz stable and I eventually went to the EVGA forum where they told me it was my board. 15min later I was in the car driving to FRY's.

I just downloaded core temp and my temps read a lot higher than in the uGuru. 63 instead of 58

[icon57]

i think your 720b is a known good clocker btw
i am not at my comp , so i dont recall exactly the proper name, but in the bios,
i have both htt set at 3x
alot of people dont talk much about this setting
for me it make all the dif between booting or not
give it a try and see if that help ya.

[CikaNovo]

Thanks Icon57,will try that and post back.Already tried x4 multi with no luck.

There it is, in all it's glory.

Settings i'm currently priming at still.

VCore: 1.45v
VFSB: 1.5v
Memory: 2.1
can't remember the order for the other two that come next, but they are on auto.
SPP<->MCP: 1.55v

That's good for 400+ FSB I'd say..
Add more vCore as needed. Go up in increments of 1 setting as it fails prime, and you will soon fine your max and what is required after you prime for a bit. Remember, SMALL FFTS! and nothing else! Blend does mostly ram, and is useless, especially if you leave your memory at DDR2 800. It really doesn't need to get a WHOLE lot like other people like to say, or actually do. They are just silly. These SHOULD be the ONLY settings you need to set manually and leave on auto. Applying too much voltage can of course cause instability too.

Hope this helps..

[CikaNovo]

Thanks again for settings.Will try them as soon as finish with x3 HT testing,and will get back to this thread.

Eh, you don't need to do that... I'm still running mine at 5x, and it's perfectly fine.

If you are using Windows Media Player 11 that is the problem it SUCKS and is unstable!

[NKD]

well just installed my q6600 g0 in the evga 680i A1, with the p35 i was able to hit3.6 with 1.39v loaded and right now i am testing my first oc at 3.4 with 1.32v loaded on the 680i. i will be trying more after i have tested this for stability. sorry coretemp restarts my computer i dont know why, so i am using tat, tells me the temp on 2 cores. all this is on water, dual readiator d-tek fusion on my cpu.

[NKD]

her finally some shots of my new rig. waiting for my 8800 gtx's, right now living it with the old 6600gt

[NKD]

i am testing at 3.6 (450x8) right now 40 mins in to prime. mem at 2.2v, cpu at 1.5v in bios and 1.408 loaded, this chip needs only 1.39 to do 3.6 so might reduce that a little if its stable at this speed. NB voltage at 1.55v, and all other voltages at 1.4v.

coretemp at 60c on the highest core. i used to see nvmonitor way off core temp when 680i first launched but nvidia seems to have programmed nvmonitor to adjust to core temp, nvmonitor now with the latest bios reports exact same temps as core temp and tat actually shows my temps 5c cooler than coretemp at 55c on the coolest core and 56c on the hottest core.

Im having problems too with geting my Quad G0 stable, but a lot of thing changed when I set FSB voltage to 1.3v not 1.4v and 1.5v, yesterday I was taking way to get stable 425FSB and it was successful, before with high FSB I was able to get 400 x 9, but it was not posible even boot at 430 - 440 FSB, now with lower FSB voltage I can boot fine with 450FSB or more in bios.

Yesterday testing gave me 425 x 8 = 3400 Mhz and it was set with 1:1 momery @ 850 Mhz 4-4-4-8 2T! Got it 8+ hours Quad Prime stable A lot of voltage tweak is needed and every board acts differently, 425 FSB will be tested with 9x multi today, hope my board can do Prime on 450FSB with Quad

And by the way here is my max CPU validation on water, not too bad - 4.3Ghz from 2.4Ghz And it looks like its boards limit, as 480FSB on Quad and 680i is very high. Must get 500FSB posible Quad board for testing this more When I will get it for 24/7 then I wil try to get few more Mhz, vdrop mod will be done too. Now the limit is free time for all this!

I see you have 720B,same as I do.What are the the other voltages you used except FSB voltage of 1.3?Are you still on X4 HT multi?

[Kashelz]

Yes, im on 4x multi, I was runing 3x, but that was not good for 400+ FSB, increased to 4x and all is good now I can post my voltages later when i will be at home, but they are not firm, I just tried and they worked, maybe for 425 x 9 i will need to add more not only vcore. Keep trying
