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

[aka1nas]

Are you running the P30 BIOS?

If that's a B3 stepping, you're probably at the limit of the chip.

You also might need to up your FSB voltage up to 1.4v to get that high.

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

Sorry Nuzgo, I am talking pencil mods for the GTX. The are really simple pencil mods for Vdimm and Vcore. Highest I had the clocks were 710/1140 and there was room for more voltage. Dont want to smoke the card but I think I can get more from it

Has anyone found a workaround for droop on the 680i or is it a regulation problem?

[nugzo]

I'm not doin so bad in the FSB department with my A1 570 MCP

[strange|ife]

sorry no results here. i chucked my 650i board.

i was a long time nvidia supporter on the AMD front, and for the most part didnt have any problems, ever since nforce 2 days. Except the blased a8n32 dlx, which i still have chillin in a closet lol..waste!

i went over to intel 6 months ago, and went through 2 EVGA's..within 2 weeks. Nothing but headaches, and smashing my fist on my desk. i then bought the p5n32plus..worked for 2 months, and then became flakey, the board still runs though..just became a flake.

my advice, i would probably wait it out for x38 if you already have nvidia stuff at this point.

or you could go ip35 pro, or p5k. ALOT less stress in your life.

*knock on wood*

I too have a huge FSB hole between 1500 and 1600. I've got my Q6700 at 3.55GHz, Orthos stable but that's as far as I can go at the moment.
If you have links for the 8800 pencil mod, I am interested. Also, any links for pencil mod of 680i would be helpful as well.

I got mine stable finally !

Have got a go with the extremely good priced LT so i bought the EVGA.
Is selling in germany for only 100 Euro

First impression is the simple bios with a few less options than his big brother.
But as i read on the EVGA forum you can flash the LT with the bios of his big brother as long as you force the flashing through awdflash.

This gives you a few more voltage uptions and also ups the MCP voltage to 1.75 Max (LT default is max 1.4V)

Got up to this now
I am realy pleased with the following result



Don't put the LT in the discount bin just yet !

I'm 10+ hours orthos small fft stable @ 3700mhz, 10 loops of 3dmark 06 stable, No general crashes or issues at all untill loading up counter strike source. I had to drop OC to 3300mhz before lock ups stopped. How are you guys with 3600+ doin in games? You'd think if it looped 3dmark and passed orthos like it does, css would be no problem.

[icon57]

^^^ true....
was that the only game that locked up? try a few others and let us know...

[hifiking]

I got a X3210 and an EVGA 680i. A1.

1.6 vcore set in BIOS, 1.54 real.

Watercooled and lapped, 3,5GHz stable at nearly 70C load. Coretemp

All other volts at auto.

The board is in for RMA because when I set the RAM volt to the default for my chips the board have loads of errors in memtest.

Phasecooling is heading this way, so when I get my new 680i back I will try higher volts on the X3210.

Hosted a 2 vs 2 vs 2 vs 2 Supreme Commander game (Supreme AI, 1000 unit cap, 60km x 60km map) with a friend a few days ago with zero hiccups at my current settings in my sig

Other news, was able to boot at 450FSB @ 8x multi. Willing be posting results later this weekend.

Hifiking: What RAM are you using? If it's anywhere over DDR2-800, you're probably erroring in MemTest due to lower-than-recommended voltage for your memory (EVGA 680i defaults at 1.85v for RAM if I recall correctly, which in many cases isn't enough for DDR2-1000 if that's what you're running).

[politenessman]

l723a. vid= 1.2000v

wont post at 9x400, but ok at 8x450. 1.45v vcore in bios, 1.37v in windows. temperatures absolutely nuts, like 50c idle, 75c load with ultra 120. hs/f making good contact, sometimes is actually hot to the touch!! i can see where this is heading. considering spending around $150 on a p35 board, which is a shame, this board has been flawless since november, and overclocks my g0 stepping 6850 great. any sugggestions on a p35 board around $150 ? no msi plse.

Q6600 B3
Evga 8800 GTS 640 @ 640 x 1000
Ballistix 2GB 1066
Corsair 620HX
Air Cooled with Thermalright Ultra120 Extreme (lapped for 5 hours)


here are the results of my humble B3:




But it seems no matter what I do I cant get this B3 prime95 small fft stable above 3.3ghz, so I dropped the multi down to 8

edit:
these are the bios voltages, except cpu is now at a lower multi so lower vcore too.. it was at 1.6v

[Metric]

3.7GHz [411 x 9]. Voltages haven't changed since my previous 3.6GHz post.

What programs should I use to overclock and test stability? I have the A1 revision and a G0 stepping?]\

Btw, I read the stickies but I was wondering what people with the same parts as me were using.

Overclocking:

CPU - BIOS
GPU - SysTool/ATITrayTool/RivaTuner

Stability:

wPrime -32M Test.
Prime95/Orthos - 4 threads, 8 hours minimum.
3DMark - At least 3 cycles or more.
Stanford's Folding@Home SMP Client - 6+ hours w/ "-forceasm" flag
SuperPi - Couple 32M runs, one for each core.

I think this may be a video card issue. Now i cant do 5 loops of 3dmark 06 at cpu default settings. I took my water blocks off a month ago and maybe i didnt get stock hs fan back on correctly. I've reseated 3 times yesterday using various thermal compounds..(including old thermal pads) Better but still locking up. I'll have my RMA'd ultra back monday to verify. Off topic i know but does anybody know where i can get some thick thermal pads for the memory?

Back on topic. I used Turtles voltages( fsb 1.5, spp 1.55, mcp 1.65, ht 1.55) to get 18hours prime stable @ 3700mhz. I am not using water on the chipsets lke he is but i am using after market HS and Fans on the north and south bridge. Swiftech MCX159-CU Copper C110 Fan&Heatsink and Evercool Twinkling VGA Cooler. I do not think the stock Heat pipe solution can handle those voltages.

[zodduska]

what are you guys using to monitor Chipset temps? Speedfan shows an impossibly low system temp for me, and I assume Everest "motherboard temp" (the same shown in NVmonitor) is ambient.. because it never seems to rise with load.. the only place I can find this temp sensor is in the bios.

I used these same exact voltages with my 3.6 OC. I'm stable using Prime95 for nearly 2 hours, but when I enter a game... *crash & reboot*. Lower my OC and the problem is gone

I'd post screens but these are the same voltages. I'm at 9x400 and RAM at 2.1v 4-4-4-12 timings.

Any input? My BIOS is at P30. Thanks!

2hrs prime stable does not mean your stable. You need to be able to run 8+ hrs with no issues. And even that does not guarantee stability.

Prime95 isnt the only way to test stability...ive had prime stable comps at 8+ plus but fail ingame arfter 20 mins.

ive had prime fail instantly, yet i could game for HOURS and never a single crash...weird.
test for stability 460 x 8
will post back, with results

Here is my 24-7 crunching overclock, it has been running 100% on all four for about 28 hours now:

no joy...i woke this morning to bsod "machine_check_exception" while running prime for an overnight run at numbers listed in sig.

however, long gaming session last night on bf2 and no issues at all, or in any other ares, just cant orthos, or prime

any ideas....anyone?

[GAR]

This is what i got so far, and seems to be the max......i might be able to hit 3.6 with water......preety good chip for a B3....both cpu and heatsink have been lapped. It is P95 stable....1.47v with vdroop.
