evga 680i A1 D00 + e6700 (week 27) = 10x360 works, 9x400 Does not...

[jeeka]

What am I doing wrong here? I can't boot at all at 9x400 with my e6700. Is it because the machine is trying to initially boot at 10x400, then squashes the multi down to 9 right away? 4ghz is not happening with my setup.

At 10x360, My BIOS Settings are:
CPU Core: 1.5625 on the vCore in BIOS (1.52v real)
CPU FSB: 1.5v
Memory: 2.1v (RAM from sig)
SPP: 1.4v
MCP: 1.5v
HT nFoce SPP<--> MCP: 1.45v

When shooting for 3.6Ghz w/ 9x400, I change the SPP to 1.5v and even jack up the vCore to 1.6v to see what happens (since this board has such a huge vDroop) and Bam...... no Post...Don't tell me I have a bunk MB....?!

Can any of you guys give me suggestions as to why this is not happening?
I see people all the time lowering the multi and still booting 400+ fsb with "higher" multi C2D's (6600,6700, X6800).

Also, How are all of you getting 3.6Ghz with LESS THAN 1.53v ?! Lucky bastards. I need 1.56250v-1.6000v and I'm not even ORTHOS stable!!!

Lucky, Lucky, Lucky.
Thanks for your time!!!!

Bump

[dinos22]

suggestion is to start slow

take 5MHz FSB steps on 9xmulti starting at around 340

[Makubex_GB]

Why are you using such a high CPU FSB voltage?

So far I've taken my FSB to 471MHz with just 1.3v

1.4fsb here is money for 475mhz 590sb a1 board

That's what I am asking myself! My e6600 nor my e6700 will boot with anything less than those voltages at those speeds.

I will start at 340x9 like dinos22 suggested and see what that lands me at.

I'll also lower the FSB volts to 1.3v and go from there.

I'll report back! This might be helpful to those who are in the same boat as me.

Thanks!

Ok, the best I can get, at any combination of voltages at with this e6700 @ 9x is 375*9.

That puts me at 3375Mhz, This is so lame....

Is it trying to boot at 375x10 first? Just like my P5WDH? I am so confused.

I mean, I'm not crying about the CPU speed, I can sit at 3.6Ghz 360*10, but I
want that extra RAM bandwidth and so my RAM runs at it's factory rates specs.

I am a multimedia/rendering After Effects/DVD geek and I would like to finish 8 hour renders in 7h30min if I run them overnight, especially when deadlines are tight. Short renders only save me seconds at best (renders of less than 5 minutes of source video). But this is huge when you extrapolate that out over hours...

So I am not doing it to be a CPU Clock fanboy at all. Just want the most I can get with the goods I have.

Thoughts?
Thanks!

Can anyone suggest anything else besides going H20?

[dinos22]

maybe just sell it off and get a P35 chipset mobo

[adamsleath]

is the p35 guaranteed to give him higher fsb???

is that the main advantage of p35? any other p35 benefits? asking cos i want to know...

[Leeghoofd]

I would drop the multi Jeeka to eg 7X and try to get 400FSB goin. This should work at stock Vcore and CPU VTT settings though... have you replaced the thermal pad under the NB ? Some EVGA users had some real bad goo there getting the NB temps into dangerous regions... I don't have an EVGA baord but the Striker Asus versions and to me those voltages seem way too high to my taste... for comparison for 1600FSB

CPU Vcore : 1.4750 set in bios 1.42 in windows under load for my E6600 32a
1.2volt : 1.35
NB voltage : 1.45 ( boots with 1.4 to 450mhz though isn't stable at all)
SB voltage : 1.55
CPU VTT : 1.45 (if I leave this one below 1.45 It would boot but any overclock above 400FSB would cap out on me under 5 minutes)

[jeeka]

Hi Leeghoofd,

I sure have cleaned out the gunk on the SPP and MCP, as well as the Mosfet heat sinks near the upper left of the MB as well as the set of Mosfets that have the sink on them at the top of the MB (above the CPU). I slapped on Arctic Silver Creamique on those, have a Thermalright HR-05 SLI heatsink w/ AS5 on the SPP as well as a Vantec Iceberg on the MCP w/ AS5. My CPU sits under a Thermalright Ultra 120 and a 120mm fan blowing through it, out the back. Temps are good on those. That gunk was horrendous, like powdery clay. I didn't even boot up with the stock setup on there. Didn't want to give it a chance to "melt" in.

I'll try 7x400 and see what happens. I have a feeling I am doing something really really stupid. There is no way this board clocks worse than my 1.85vMCH P5WDH.....(soon to be my wife's if this 680i turns up golden) :)

I'll report back soon.
Thanks for the input!
jeeka.

[jeeka]

WOW this is REAL lame..... can't boot at 7x400, even bumped up voltages and everything....anyone have any insight to how lame:

1) I am or
2) what a rip off of a board I might have got.

[Lord_RTKK]

Some 680i boards have problems with certain FSBs...

For example, one of my strikers did up to 2000 Mhz of FSB passing 32Mb stable, but at 1800-1900 interval it doesnt boot at all...

Try a higher FSB with a low multiplier to see if it is your problem, I think that it is...

Try for example 450 (1800) or 475 (1900) to see if it boots (doesnt matter if it is not stable, the important thing is that the mobo boots or not). If it boots, you know that your mobo has a interval of FSB that doesnt work... ;)

Try it and tell us the results.

[jeeka]

Hi Lord_RTKK,
I have tried (450-475)x7 and still no boot. Unless I am doing something really really idiotic, I think that I have a bunk MB.... I had such high hopes for this one. It was the exact MB rev of the board I wanted. It has the 570 MCP on it.

I have tried p27 and p28 with the same success... Application of all components was clean and careful....

This e6700 does 3.65 on my P5WDH, so I am lost as to why this "superior" clocking board is taking a dump on me....

Could someone who runs their e6700 at 9x400 enlighten me and post your voltage settings and/or anything that would need to be set in BIOS that I am overlooking somehow?

Thanks!
jeeka.

Update:

I threw in my e6600 and it booted first time with 9x400. It was not Orthos stable but I was able to scoot around Windows and work in Photoshop for about 2 hours before it reset on me.

So, now that I know it will do 400FSB on an e6600, I am still confused as to why it will not boot my e6700 at, 7x400, 8x400 or 9x400. Before throwing in my e6600, I even tried 7x475 (RAM at relaxed timings) to make sure there was not some 100FSB hole from 375-475.

So odd, any thoughts on this?
___________________________________

Also, I lapped the e6700 to a mirror finish using 400 grit, then 1000 grit, then a 2000 grit finish. I slapped a super thin layer of AS5 seeing as the chip and Thermalright Ultra 120 are both lapped to a mirror finish, and now my temps have dropped 3°C idle right off the bat at same voltage, hopefully more when the AS5 settles in.

Also, Instead of 1.6v BIOS (1.55 real), I can boot into Windows stable at 1.55v BIOS (1.51v idle)...I have not tried lower yet.

I cannot confirm if it's due to the lapping somehow, or the reseating of the HSF, etc, etc, etc...

Just wanted to share my adventures in mid-upper level c2d OC'ing with the evga 680i.

jeeka.

[pumbertot]

try other FSBs near that e.g. 405, 410,420 etc. mine has FSB holes all over the place. I cant get 400-410 stable but I can get 420 stable. again 430 isnt but 440-460 is. dont give up yet.

[jeeka]

I'll try that.

But why would the MB boot at 400x9 on my e6600 on not 400x9 on my e6700 then?

I don't get it at all. My suspicion is that it tries to boot 400x10 and does not have the guts to do it before it squashes the multi to 9. Can anyone confirm this? I highly doubt this seeing as people are boot in the ~500 fsb range with lower multis...

Also, I have no idea how you guys are getting ~3.6Ghz with ~1.5 volts or less... I have to throw 1.6v BIOS (1.55v Real) on both my e6600 and e6700 with both my P5WDH and evga 680i.... My luck must not be as good as all yours'.

Thanks.
jeeka.

I think it's all got to do more with correct voltage,timing settings ram dividers etc then solely the CPU, if they both did 3600 on ya P5W they both should do it here, for starters it seems you got 2 bad batches due to the fact they require so much voltage to get stable... I have 2 E6600' s now and they require different voltage setup on the same board. As for the 500's FSB I think many clockgen there way up to 500...

Mobo's can be like CPU's you got excellent ones that run fab out of the box and some just don't cut it... I'm pretty happy with my Striker though many are really upset why it doesn't work for them...I've never reached 500FSB, 475 is the max here but I don't need 475 for day to day basis...

Also for the holes to find small increments work better , instead of 450 I had to use 453 before the newer bios solved that hole...450 wouldn't boot before no matter what voltage or setting was there...

these 680i boards can be hard to setup though once you get the feel for them they are amasingly stable...

I just wished some EVGA user would post his settings here so you could compare more easily
