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

[Ic3man]

Closing in on 3.825 Ghz needing 1.48Vcore, RAM running 900Mhz.

Settings are

Vcore 1.53125
FSB 1.5
Mem at 2.1
SPP 1.55
MCP 1.65
HT 1.55

Using the 9 multi still so that puts me at 425 FSB.

Did you need to raise the SPP,MCP and HT voltages to get stability Turtletrax? Did you add a 2nd PSU or are you still with the zeus? What do you think sorted the problems you were having out?

I ask becuase I have vitrually the same rig but a Qx6700 on the way.

How accurate is the vCore measurement from CPU-Z or Speedfan for this board? If I set it to 1.3v in the BIOS, I end up with 1.25v-1.26v on idle in Windows and more like 1.23v on load.

your bios, windows, and load voltages are the norm for EVGA 680i's. I use everest or speedfan to monitor voltages in windows. I'v yet to see cpu-z show correct voltage. speedfan and everest show identical voltages.

Ya, I had to crank allot of voltage to to the MCH, SPP, and HT to get into windows even. Also found I had to lower the MCP and SPP links to 3x to get stable at 4.0Ghz.

I am still with the Zeus 750. Problems vanished as quickly as they aroze. I have no idea what was up with that. PSU is rock stable now as it was in any other build I had it in. Very odd....

Cool. Hope I can get 4ghz with my quad

Hi Guys,

I'm having some growing pains with my 680i A1(P30) and G0.

My E6600 runs @ 3.6 no problem. I had a B3 that would run 3.2. Since then I've purchased 2 G0's, this is what's interesting. Neither one of them will get me past 1200 fsb regardless of what voltages I throw at'em, if it's under 1200 fsb then all is well, but the minute I go over it, I get BSOD's with *hardware failure*

I tried it out on a P35 Gigabyte DS3L and oc'd to 3.2 without issue.

The common denominator is the G0. Called evga on it, and they're testing the new stepping to see if they can replicate. At this point, it appears to be a board issue.

I saw a post in another forum that NVIDIA was working on a BIOS update for the G0 quads. Until then, I'm running @ 1200 FSB with RAM at DDR2 800. Still fast as poop, but faster is always good

@turtle.... Do you have the 570 or 590 MCP on your EVGA? Is your board retail or an RMA'd board? It seems most of the RMA's are 570.

Thanks nullptr,

I hope that helps, but I have a feeling my issue won't be fixed with a bios update, the fsb just doesn't want to go.

GO Q6600 running as well as the B3 QX6700.

Ok i'm a little happier now. My 3rd G0 is clocking as i was hoping for on the EVGA. The first 2 (L723,L724) i couldn't get stable even at 3200mhz on this board. My tank guys L724 just arrived today and i'm priming now at 3700 mhz 463*8 at 1.55v Bios, 1.50v windows 1.46v loaded small fft's. Temps fluctuate between 55-64c. I may be able to lower vcore, 1.55 was just my starting point.
I'll post screenies and benchmarks after testing some more.

I have a 590 MCP and it is retail from the shelf. I bought it and had one that was acting quite funky, so I took it back to the retailer and got another retail box.

I am going to lose 2GB of ram and go back to XP and really go for max clocks on proc and RAM. Have me a little benchfest, see what I can get. I am hoping for over 15,500 single card in '06.

[nugzo]

good luck on 15,500. i just hit 14,654 @3700mhz Default settings on the ultra.

My boards dead, it *locked* itself to a 26x multi that's why it wouldn't boot, just didn't want to fire up a little over 8ghz.

Now, I have to clear the cmos every time to reboot in order for it to start, and will only run @ 1.6ghz, which is where it locked itself....give it an hour and it may once again change the multi.

Is there differenties for fsb clocking?

I had the 26x multi on the shipped P27 BIOS, but after flashing P30 it was recognized properly. I think it's pretty common.

I've got my G0 Q6600 running at ~3.6 (407*9) unlinked with mem set at 1067

Settings are

Vcore 1.55 (1.52 in windows and 1.48 under full load)
FSB 1.5
Mem at 2.2
SPP 1.5
MCP 1.65
HT 1.5

I've had P30 since the day it was released, there is others right now experiencing the same problem at evga's forums.

on C2D some said 590 was better for FSB. I've had both @500 with a e6600. I haven't read or heard of anything "official" though.

I've had a flag in device manager on 2 different boards with the P30. Do you have that same problem?

[Flinch]

Yup, fortunately, over time it's gone away.

I think I can do it. I got 14,500 without my pencil mods on Vista. Also had loose timings on 4GB of RAM. Also hadnt tweaked my drivers for 3D at all either. XP/2GB RAM/tweaked/Pencil mods/4Ghz Q6600=pretty fast in my book.

Will let you know.

U talking about pencil mods for the EVGA 680? If so, would you link me to them please. Thanks

I got a Q6600 with evga A1 and I am STUCK!! I can't get this fricken motherboard to even POST past 1500qfsb. It's making me mad. And the CPU has a lot of potential i know. I can only run this thing < 3.4GHz. The CPU temps r no where near high and I have a swiftech water cooling, all for basically nothing because of this crappy FSB limit.

I tried maxing out all the voltages for motherboard (FSB,SPP,MCP). tried unlinked with RAM at 800/1066. tried 3X PCIe<->MCP multipliers tried 8X CPU multiplier, turned basically everything u can disable to disabled in the overclocking menus and it still can't post at 1501qfsb. wish i can exchange and try another board.

[zettahertz]

ok... that was weird... huge FSB hole. running at 3.55 now. things in between doesn't work... whew, thought i had a dud board.
