I am In OC Hell P5N32-E Plus and Q6600

[maverik-sg1]

OMFG!!!

You know looking at the features of the 680i based board you would think this would be the proverbial puppies privates - often touted as an excellent alternative to the best of the 965 based boards around.

It's official - been away too long and feel out my depth, or in fact this is not the best board for Quad cores - either way I am stuggling and need help.

The BIOS is feature rich and I must admit confusing, just as I got used to Intel chipset based overclocking - it does kinds resemble the skt939 DFI style of BIOS - which once you know what you are doing is great, sadly I do not.

So anyone with a 680i based board that can assist with overclocking a quad chip or in fact any BIOS screenies to what works best would be useful.

Cheers

I am pretty much in the same boat Mav,but if you list where you are at and what settings you are struggling with i will try to help you out.

here ya go mav all the tec briefs for the 680

same chipset altho diff manufacturer but i believe its similar

the overclocking guide has all the stuff ya need to disable to overclock the a 680

might be of use

[Thickbrit]

Wow,i don't think you did too bad a job setting that up mate.There is not much i would have changed,other than lowering memory to eliminate that,setting ht freq (or equivelant) to 4x,maybe upping the northy volts and trying the other voltages.You could also try mem timings on auto.All your pci,cpu and spread spectrum options are fine.Have you tried jumping over any possible fsb holes,which the 680i is notorious for.

 

[maverik-sg1]

I would but dont know what the holes are - in fact I recall Kenny saying the same thing a while back.

I might just use this to spank out some scores with X6800 and to SLI 2x 320mb GTS's - me and blindfitter got a new toy on it's way for use with quad

 

[maverik-sg1]

Please tell me I don't need this mod?

[Thickbrit]

lol,yep,IMO that is the only way you will get any joy from your quad on that mobo.I only hope your mods work as per the guide,unlike mine.

 

[maverik-sg1]

Any joy using a core2 instead?

 

[Thickbrit]

Core 2 will prolly be fine.

 

[maverik-sg1]

Right will try some core 2 action today - but gonna apply the pencil mods for vcore and vdroop as the reported volts are way of my required volts.

Still 450x9 is not gonna get me the speeds I want under phase anyways - looks like I will have to save the quad for another day.

I read the GTL mod works best if its set between 0.95 and 1.1v - 1v seems to be the one that works best reading around.

How comes they don't have this issue on the striker board?

Lifted from a Post at XS which might help if the mod did not work:

Did the mod exactly as it has to be done and the result now is that system won't initialize the CPU. All the voltages are OK - vCore reading 1,26V, vRef = 0,87 (originally 0,77; tried up to 0,96 and down to 0,66) - still no go. Unsoldered the variable resistor and put new one in the place of the originally installed on the board (214ohms) I had to unsolder to do the mod - the Striker still refuses to initialize the CPU. Any ideas what could have happened, or all I can do is get a new board?...

One more question - with the removed 200ohms resistor and soldered 500ohm, I couldn't up the GTL Ref voltage more than 0,96V, however I read in this thread people are using 1,1V... how is it possible?

EDIT: RMA'd the board, next week getting a new one, hopefully. Getting 3220 pretty soon too, so I will definitely need the mod for 400+ FSB and I need some opinions what would have gone wrong last time; is it mandatory to remove the resistor, as Shamino gives instructions, isn't there a possibility for the mod to work without doing so?... And is 500ohm VR fine - as I said, I couldn't get more than 0,96 vRef, (I saw Kunaak uses 1K, maybe this is the way to go).

Well I give up

This is deffo one POS board - welcome to ebay you mofo mobo!!

Runs at stock - rest of it is lots more trouble than its worth.

I doubt very much if my future boards will be Nvidia based so I look forward to X38 with SLI.

This whole thing has been a massive learning curve - which although ultimately fruitless was at least worthy of a mention that the features on this board are the future - just have to be adopted by anyone other than Nvida based chipsets to run properly.

So on the fun side - I enjoyed learning a new BIOS set-up and enjoying the fruitless potential of being able to adjust the ram totally independant of the FSB of the CPU.

The sad fact is that this board disappoints in a way that I am unable to put into words.

Given the opportunity to use one again - I would rather stick hot needles in my own eyes or pull my own teeth out with a set of spoons!!

 

[maverik-sg1]

Sorry I forgot to put results down:

330mhz x9 FSB, 380x8, 400x7 on Quad 1.4v, 1.4v and 1.34v true (1.45v BIOS)

460x9 or 445x10 on core 2 X6800 1.6v (1.6875v BIOS)

Used BIOS setting as above

No improvements on benchmarks

Ram unlinked would run at 1190mhz 5-4-4-12 (corsair dominators PC8500)

I look forward to testing the G0 6600 and X6800 on next project in approx 7 days although still bitterly disappointed that I was unable to improve and the board proved to troublesome for me to want to try SLI on it.

As for SLI now - this board has made me wake up and smell the coffee.

I might as well wait and buy a Nvidia 9800 (maybe even GX2) as this will (allegedly) have a 50% performance (in GTX flavour) leap over current 8800Ultra's (more with GX2) - and should therefore reach the CPU limt on one card rather than using two and the cost will roughly be the same investment as 2x640MB GTS's (more for GX2 clearly) and give better overall peformance.

So will wait to see some reviews before deciding which one to get.

 

[stocky]

yeh, I don't think anybody has much luck with those 680i boards. I've luckily stayed clear of them, although the Black Pearl edition does look nice

The X38 are due out anyway, which is when the real fun will begin!!
