Anybody noticed these cpl chips running flaming hot? They burnt my finger when I was priming.

thanks to eva for the image.

My problem is that I can't really prime anything over 3.5Ghz with Q6600 G0, although the G0 is stable at 3400Mhz @ 1.29v

Anybody noticed these cpl chips running flaming hot? They burnt my finger, 100C+ for sure when I was priming.

My problem is that I can't really prime anything over 3.5Ghz with Q6600 G0, although the G0 is stable at 3400Mhz @ 1.29v

Mine only run around 60oC measured with an infrared/laser thermometer whilst priming 3.7GHz with 1.45v to the CPU.

100oC would take skin off your fingers are you sure they are that hot or was it just a guess.

It was just a guess, educated guess Nevermind, those probably have no effect on stability, I have to work on priming. The cpu either primes or blue screens, I never seen prime giving any errors (such as rounding errors).

As I am starting to wind things up here now I have put a panflow 120 blowing on my PWM & NB area & those digital PWM chips only run 45-50oC loaded so I am sure they have plenty headroom left.

The single most important thing for my CPU to run stable is CPU VTT, I get crashes & reboots unless its over 1.55 but to be safe!!!!! I have mine maxed out at 1.60v

Why don't you try maxing the VTT out & see what happens, also keep your ram way out of the equation until you find a sweet spot for the CPU as the RAM timings like RLM has already mentioned can have almost the exact same crash symptoms as the CPU.

Speaking of 'Hot" does anybody know of a waterblock that will fit the mosfets on the DFI?

you have use Abit IP35 Pro.. how can you compare it to DFI LP P35??

[wedfighter]

you have use Abit IP35 Pro.. how can you compare it to DFI LP P35??

i'm using both of them
the IP35PRO has a easier OC than the DFI
i mean the OC not a BIOS option
DFI usually had a random C1 error, and the ABIT has easier error recovery

bout the vdroop as we knew, ABIT only use 4 analog phases, compared to 8 digital pwm on DFI it's very2 normal if ABIT has a bigger vdroop
but from IMHO eventhough its vdroop is bigger than DFI LP P35, IP35PRO has very-very easy for OC

DFI should work on a BIOS fix which make POST easier
coz we knew from the layout, DFI should done a lot better than ABIT

ohh.. mm.. hope DFI fix it.. but maybe a little more tweaking will do.. you know DFI.. hehehe

Slightly off topic but my IP35 Pro rocks with C2D & Quad what problems were you having?

Q6600 @ 3700MHz http://s106.photobucket.com/albums/m...208%203700MHz/

E6600 @ 3760MHz http://s106.photobucket.com/albums/m...208%203760MHz/

I just got the DFI last night hooked it up & within an hour ran 525 x 7 3D stable with my E6600 on the stock Intel Heatsink!!!

Although I could run 540fsb on the IP35 Pro it was not stable & would freeze in 3D (3DMARK01, 03 ,05 06 etc) so I think the DFI will definitely run higher fsb easier however it is atm (very early days) on auto timings & significantly slower than my ASUS P5K & Abit IP35 so its going to take a lot of tweaking

I also had problems with CPU-Z v 1.40.8 BETA so found v1.41.0 BETA which is reporting 1.536v @ idle with the vdroop thingy enabled in the BIOS, the actual vcore set in the BIOS is 1.50v so as you can see its not drooping much & as you are probably aware is considerably less droop than the IP35 Pro.

I have only played roughly for a few hours with the DFI but so far it looks to only droop 0.02-0.03v with light ish vcore (1.50) under load which is great.

Sorry for the late reply...I can't seem to get my Q6600 G0 chip past 3.2ghz stable on the Abit board...even after jacking up CPU VTT...I had no issues getting my other G0 chip up there though (E6850)...that hit 3.7ghz very stable...I still have to spend more time with the quad though...I just wanted to get the DFI board because I haven't had one of their enthusiast boards since the SLI-DR board...that and I'm getting phase very soon

[C-N]

you have use Abit IP35 Pro.. how can you compare it to DFI LP P35??

Chalk & cheese the 2 boards probably could not be any further apart if you tried.

Don't get me wrong the Abit is imo a fabulous board especially when you consider it costs 1/2 the price of the DFI but at the end of the day if its an enthusiasts board you are after the DFI wins hands down.

The Abit offers great mega rock solid performance straight out of the box with a super simple setup for a very decent price it definitely gets my

The DFI is eye wateringly expensive & takes a lot of tweaking & tinkering with just to match the Abits performance however the DFI can run anything you throw at it, it will bench just about anything you can dream up to try on it & you can tell where the money has been spent (PWM & Heatpipe) as it runs amazingly cool even ringing the nuts out of a quad & the voltages are super stable.

Here are a few of my major pros & cons.

Abit Pro's: Excellent board layout, Great performance, Easy setup, Good Value, uGuru overclocking & monitoring software is outstanding.

Cons/suggestions for improvement if I really have to say something remotely negative about this board: Beef up PWM, make heatpipe heatsinks flat so we can mount fans on them, add on/off reset buttons to board like DFI/Asus etc.

DFI Pros: Makes bootable stable fsb really easy, runs cool thanks to the great heatpipe, 10 billion setting for the enthusiast to play with, performance flexibility from 2-4ghz DDR600-1200 CL3-5 is great it will run anything, EZ clear/CMOS reloaded & the onboard on/off/reset etc etc etc basically all you would expect from DFI.

DFI Cons: Memory slot clips foul on graphics card (too close) however they are not un usable just an annoyance but one you can live with when you consider the amount of PCI-E/PCI slots the board has. Smartguardian sucks now I have been blessed with uGuru on the Abit & thats it for now remember I have only had this board for a few days.

The Abit IP35 Pro uses an analogue 4 phase PWM which runs cool with a dual core even @ 3.8GHz it only just hits 60oC passively cooled which is far better than any other board out there like the Asus, Gigabyte & MSI which I count as one of the boards strong points as this means average Joe like my self can get a blistering overclock from this board straight out of the packet on the stock heatpipe.

As much as the simple Analogue PWM is an advantage for dual core it is unfortunately the Achilles heal for quads as it really struggles to provide enough juice for a quad & although it can do it the PWM is over stressed & then runs blisteringly hot & therefore needs active cooling which can prove difficult in most peoples cases as its all part of the heatpipe system & its a half moon shape heatsink that makes it very difficult to mount a fan too provided you can even get at it with a decent big CPU heatsink installed.

If you like playing with RAM timings & experimenting lets say from say CL3 DDR700 through to CL5 DDR1200 then again the DFI is your weapon as it will run anything you can type in provided you have the nuts to give your DIMMS the voltage. The Abits timings are super basic with most of the timings the DFI has being hidden from our view in the BIOS. The Abit however does a really good job of getting the most out of your RAM with virtually zero input which again for a plug & play board has the best performance straight out of the box of any board I have to date including the DFI P35.

Hope this helps

Overclocking can be a little hit & miss sometimes & hopefully a bit more play time will get you going.

The Abit suffers wicked vdroop when you start pushing a quad perhaps you just need to juice up the CPU or maybe do the vdroop mod although I haven't done it on mine & I can still pull 3.8 prime stable for hours.

Anyway if you have got a DFI LP P35 on the way I cant see you being too bothered about playing with the Abit & quad, as someone that cant help my self tinkering about with things I cant help but keep buying DFI's I can tell you now if you are anything like me you are going to love the DFI's BIOS settings.

I do love to see a bit of Phase action good luck & don't be shy to show us what you can do with it

[terroristone]

having fun with my q660 B3, i don't get alot of time to sit down and play with my setting s for hours on end, i've got it stable at 3.2 but beyond that it's becoming a real pain, im running swiftech watercooling, just wondering what temps you guys are getting with the quads on water???? im starting to think my block isnt seated right, 1.55 vid con wim getting upto 70 degress and that with 423x9 3.8... also using the stock bios as i did upgrade it and everything except the defaults gave me the "C1" error.

very nice insights..

hope the manufacturers will look into our needs.. a little bit more..

thanks.. hope DFI will be on time when X38 arrives..

[Entsafter]

DFI rocks with the voltages!

2.1V Vcore (all maxed out) with Q6700 @ 5000Mhz!
No droop under load and that's a lot of AMPERE!!

But memory performance SUCKS badly... I've to try it on ASUS Blitz Formula... but on DFI

Ram that can run 680Mhz CL4 (DDR1160), can't run with 550 Mhz Cl4 on the DFI (try till 3.04V Vdimm and that's the max)...

FSB is ok (605Mhz with E6850), but the rebooting problems under LN2! SUCKS BADLY!

You better go with the Gigabyte P35-DQ6 ... or with the ASUS or ABIT.

DFI is ok for air and watercoolers, with ln2 also ok.. but only with problems and crappy ram performance...

[C-N]

Well I don't know much about LN2 but it sounds like you are having fun Entsafter remember this board is still in early BIOS days & it can only get better.

My DFI P35's memory performance @ CL5 on warranted voltages is exactly the same as the Asus & Abit I have the only real difference between the boards for me are none of the others run Quads on air @ 3.7ghz with 1.45v to the CPU on a passively cooled PWM & NB.

CN

[Entsafter]

It's probably the best board for quadcore...
but we need a better bios and better RAM performance!

CL4 is nearly impossible on this board with high fsb :-(
I'm going to wait 1 week and after that I'll change the board. I won't use quadcore till 2x 16x PCI-E Board for ATI Crossfire LN2 benching...

[chawks2]

C-N, loved your write up.

I am very interested to see how an x6800 runs on this board. Should be here mid-week, looking forward to comparing with my IP35 Pro.

Quad is madness, Im not sold on it yet. Maybe X38 & DDR3.

What's the RAM performance you talk about ?
You mean overclocking result with CL4 ? How about CL5 OC result ?
What kind of RAM you used ?

You mean it's not possible for DFI P35 to run 550 FSB/1100 Memory @ CL4 ?
And what's the LN2 rebooting problem ?

Check My result with 2 core and 4 core cpu , I think this board should work well with CL4 , DRAM used is 2 * corsair 6400C3 , DRAM voltage set @ 2.55V

[Entsafter]

Cellshock PC8000 Cl4 and Cellshock PC9200 CL5

The first pair (PC8000) can run 680Mhz CL4 on another board.. the PC9200 I don't know. But 180Mhz Difference from one board to another.... that's pretty big.

680 mhz ???? 1360 CL4 ? Can you show me shome pic that this DRAM can oc this high ????
