1333 FSB Mod, Confirmed To Be Working By Me.

The p5w64 ws most certain does support conroe.

AS for it currently supporting 1333/333 I am unsure, some of the newer BIOS releases do mention added CPU support though. There were NIC issues reported with the 05xx versions though which is why I have stayed clear of them for the moment.

Once a newer BIOS releases without the NIC issues, I will certainly be trying this on my E6600 which is most certainly more limited on this board then it was on my P5B Deluxe, mainly due to getting no POST at all if I have the memory set to anything but SPD.

Earlier in this thread Kunaak posted a list of Asus boards that support 1333MHz FSB and which BIOS revision is required. I think it was page 2-4 somewhere...

Also I'm pretty sure all the 975x and most of the 965 boards were on the list.

You mean this one?

how about ds4 rev. 1?

I so want to try this on my DG965OT but I only have one proc right now. If it doesn't work on this board will it hurt the proc?

no.

Does anyone know if the Biostar P965PT/Deluxe support for the 1333 strap?

If you want to mod PentiumD 9xx from 200 to 266 FSB then see the last two posts I made in this thread: http://www.ocforums.com/showthread.php?t=498167&page=4

Hello, knows somebody where I can obtain bios that has supported 1333 for my motherboard? thanks, a greeting.

Anyone tried this with the P5W64 WS Pro and BIOS 0502 yet?

can anyone try this on a AB9, just to see if its boots @ 1333strap?

What exactly is the ponit of this? You can always increase the bus speed in the bios so why is this so important what am i missing?

Primarily useful for folks who have cheap mobos without pci/pcie bus speed locks imo.

Asus P5WDG2 WS PRO + E6600 mod + bios 803;Not working

Hey, I have a D945, and I though since the e4400 is originally an upgrade from the D series (at least this is what i know), can this mod be done to my mobo?? I have an intel mobo and its not 975X (actually G965) and so I cant overclock it usually, does this worth try? and if this wasnt working can the mod be reversed?

The point is that when you have an new intel mobo and its not a 975X then you cant overclock even 1 additional mhz so 4 me I need this since I have DG965SS, but Im hesitated about trying this mod and I want to know if I can undo the mod if it failed. plz somebdy of how did it tell me if they can remove undo the mod back to original state

just use a qtip and some alcohol. it wipes right off. even if you don't have that, just use a napkin, some water, and scrub hard

ok well, if i cleaned it with alcohol or water wont that damage the pins, and would it be apperant that the cpu was modified if i needed to take it 4 replacement (no trace= warranty is still there), and would 266*17=4500mhz hold with air cooling?
One more thing is that 4500 needs a good deal of voltage and with my mobo in which i cant modify the voltage, will the mobo supply enough voltage?

See the link below. This is the best info you will anywhere on doing this with Presler and CedarMill. As for your CPU doing 4.53GHz, I don't know - I think that might be asking a bit too much - even if you also mod the VID.

http://forums.vr-zone.com/showthread...=89038&page=14

no

and for vid, you can always mod that too with ink

The easiest way to mod VID with CedarMill and Presler is with copper tape (conductive on one side and insulating on the other side). You can do it with ink but if you're connecting a VID pin to Vss to change it from 1 to 0 then you also need to insulate that VID pin and run the ink from Vss to on top of the tape.

Just wanted to apologize for those who I said weren't doing it right. I just confirmed it doesn't function properly with p5b. It exhibits the same behavior as ds3 with old bios that doesn't support 1333

I have tested the 200-->266 FSB mod for E4300 (posted on page 4). But on a Asus P5B Deluxe, it doesnt seem to work :( The mobo powers on and off all the time (like you changed some settings in bios).

I connected the following dots:

http://www.computer-tuning.nl/tmp/e4300mod.JPG

yeah, I noticed same going from 266 to 333. looks like the relative resistance asus p5b senses is more sensitive, or it compares bsel to microcode and if they don't match up, it triggers problems.

edit: if autozone is back in stock with more rear defrost repair kit, I might try doing a mod to drop my e64 from 266 to 200 and see if it works. if so, it should prove it doesn't compare against microcode, but rather it's the relative resistance bsel bases off is more small range for p5b

I did the 800@1066 version today.. ..and it seems like E4300 on GA-P965-DS4 rev 3.3 dont like it? Once PC had started on normal settings 370x9, but when i changed it to "auto" in bios - it just keeped rebooting.

So i cleaned the mod, thinking i made something wrong, redone it...

...and the same thing - PC didnt even started on auto settings :/

i did it like this - it looks okay, doesnt it?

Yes you connected the right dots....

And you have exactly the same effects as on my P5B dlx. It booted on the overclocked settings (311FSB). The first time I switched the pc back on after doing the mod, it booted in fail safe mode. The cpu was not ticking at 1066, but just at the default 800 FSB (1.80 GHz). But when I changed to auto settings, it didn't boot anymore.

So does this mean that the E4300 is able to utilize this pin mod?? Or just not on some boards? Im not seeing anyone say this works on the E4300.

I want to do 200--->333 pinmod on my E4300 & DS3 rev 3.3. It supports 1333 fsb. Says soo in big letters right on the box. I will probably have to do a V mod on the chip also but thats ok.

I have no question about my ability to do the mod correctly, I just want to have an idea if its going to work or not.

Thank you, and yes I have read this entire thread. I know how to do it, and have no question as to my ability to do it. But, I havent seen anyone say it works.

What I dont know ANYTHING about, is the "strap". I know it has to do with the memory. but thats about it. So the questions are: Can someone explain to my in painfully lengthy detail as to what it actually is and how this effects me and my DS3rev3.3 board?
What is the difference between the 800, 1067, and 1333 straps???
Which one is better?

Or at least link me to where I can find this info. In the meantime I will google if for some toilet time reading...hehe :slapass:

on ds3, just pinmod to 266. hang on to that 1066 strap. it'll be able to move to 1333 post400 anyway

Waht you fail to realize is that the E4300 will not go over 370FSB on this board. I have yet to find one single person that has done it. Let alone break 400 fsb.:slap:

I modded my E6600 with the 1066->1333 pin-mod. It's working fine..

Now I noticed my vcore has gone up from 1,29v to 1,41v (bios measured). My cpu-voltage is @ auto. I thought that this mod would leave the voltage at the original VID (1,3250v)?

How do i get the voltage back down without setting it manually (i want Speedstep to work).

i'm saying 266modded e4300 will break 370.

My E4300 did not benefit at all from the 200-266 mod being done.
It worked......and the CPU would boot up at 266x9 2400 default.
But it didnt seem to change anything else as far as overclocks.
370fsb was and is about it. Modded or not makes no difference.
I didnt try the 333 mod since I know I cant boot 3GHz at default volts.

Has someone done this mod successfully on a stock 800fsb cpu's?
And is it possible to do this mod on other cpu's than C2D, like older Intel's..

And is it possible to mod a 800fsb to boot on 1333fsb?

WannaGoFast, You connected BSEL1 to VSS (H30 to L30) ?

My Asus won't boot at the known mod (H30 to L30) and following configurations:

http://www.computer-tuning.nl/topics...300modBAD1.JPG
http://www.computer-tuning.nl/topics...300modBAD2.JPG

As you can see I have isolated the dots, so the high signal of BSEL2 would not leak to the socket.

When I only isolate BSEL2 (H30) and not use any silverpaint, it boots normally at 9x 200MHz... As if BSEL2 does not do anything or is just low by default, or high (H) is defined as 0 volt and low (L) is defined as a minvoltage (like -30mV) :?

Most mobos (all I've seen so far) raise vcore along with the clocks when vcore is set to auto. Mobo tries to keep required voltage and usually it's a slight overkill. :rolleyes:

AFAIK you can't use Speedstep. Please correct me if I'm wrong.

unfortunately, i haven't seen the ability to use vid transitions when setting vcore manually or auto with the p5b when overclocking. iirc, the ds3 did allow it.

on the p5b, using rmclock, you can see that it's always vid for 1.325 or whatever your cpu's highest is. changing it down doesn't change anything either, which explains why when you speedstep down to 6x, 7x, etc, it doesn't drop anything. oh well

I did the mod as pictured above, H30 to L30 on my 4300 and it booted fine at default 2400MHz 266x9 with 800MHz ram speed.

I took it off after testing it for a few weeks as I decided it didnt really do anything to help my overclock.

FIRST wait, wait. Hmm.. I didnt isolate anything on my E4300, i just connected H30 to L30. What do i have to isolate then?

From what i'am reading here (i made a @266 mod) and on ocforums i just have to make BSEL1 to LOW to get 266 fsb. So connect it to vss, or isolate it, or both?

SECOND Problem with not powering up afterthis mod may be related to mem dividers? Did anyone checked if they behave same as before? Maybe with ram set to 800mhz it were clocked higher than that?

I don't know if you have to isolate. I have just tried it because it wasn't working by simply connecting VSS to BSEL1. But isolating BSEL1 seems more logic to me, because otherwise the high signal will dominate over the low signal...

The point is, BSEL1 on E4300 is default HIGH. But connecting a VSS (L30) to BSEL1 will work on a small selection of motherboards.
In my view, it seems more logical to make BSEL low by isolating it, so the high signal will be blocked.

But this doesn't seem to work. I have some theories about this:

- On motherboards where L30-to-BSEL1 mod (without isolation) "works", the motherboard reads out a unknown value. (The VSS voltage is not in the range of the Low and High specifications of Intel, so the motherboard does not know the value). Then the motherboard falls back at its default FSB programmed in the motherboard bios (might be 266). Motherboards where this mod does not work, do not "fall back" to a programmed default FSB. They simply not boot (like p5b deluxe).

OR

- The motherboards, where the L30-to-BSEL1 mod does not work, compare the bsel setting with the bios table entry of the CPU ID from the cpu which is in the socket. So, when there is a difference, it simply refuses to boot.
So.. also an E6600 modded to 1333 or 1600 FSB will not work on these boards.

just for interest sake for those who care...
i have an e6600 that walled at 500fsb 6x multi on DFI P965-S
performed the pinmod, in post#1, to 333fsb and now the wall is broken...6x multi can now clock up to 520 fsb and my ram may be the limit there...

so for those of you who have 333fsb capable boards and can't figure out why your fsb is mysteriously stuck at some point near 450-500fsb this pinmod may help.

Same thing at my case, I did bsel mod on my E4300 Q643... with silver and they work, defult boot at 266, but I don't get any improvement on fsb. Before and after bsel mod wall is 405 fsb. Board is biostar 965pt with 0404RH bios.

Can you confirm you're doing this:
1)on the same ram, mobo and bios?
2)try undo the mod and run fsb520 with the same settings after the mod to confirm the gain on fsb20

I've done the isolate + Besl2 to Bsel1 mod with my PD940 an P5wdg2....NO Success....Still boot an 800, no 1066......Can someone tell me how to gain the 1066? This will fast drive mad......

well i think i allready posted this but here it goes again, i have a week 41A 4300 and i use to have a biostar tforce 965pt and a asus p5b-d that i tried it on with my phase change cooling,

pre mod (the 266fsb mod connecting 2 and 5) on the biostar had a 400fsb wall no matter voltage under phase, anything over 400 was unstable or wouldnt boot, tried everything,
the p5b-d whad the same wall with the 0804 bios, 400 fine anything over going up to 450 (i tried) would not boot

solutions- for the asus without the bsel modd i tried the 0711 bios, it didnt recognize the cpu correct so it booted at 266x9 default, so now the max i could clock it was 462x9 with 1.58vcore, (remember this is onphase), the bsel mod would not work on the p5b-d but the old bios did work for me

now the biostar using the 119 or 103 bios or the 921 deluxe bios (all from rebels haven ) with the bsel mod had the exact same results of 462x9, it booted right upo at 266x9 and i clocked it up the same under phase

so it works with biostar but not p5b-d but the old 0711 bios works in the same aspect

good luck

does 333fsb mod net anything more? i'd imagine it wouldn't

it gets rid of the fsb wall on some chips which does net more, its jsut not allways a workable option

I did the 1333Mhz FSb on 6300,after c cmos it boots at 2.33(333x7) but in the bios at cpu information FSB=1066
When i set everything at auto and save...then the speed is 1.86...

WTF?

Good thread guys!

Im thinking about getting a Gigabyte P35 DS4 (for the crazy cool & 8-pin psu connection which my enermax liberty 500w supports); & an e2160 cause they are cheap.

ATM all I have is crucial 6400 ballistix.

Will this mod work on an e2160? Should I even need it? I heard the e4x00 was hitting a few walls, but will an e2160?

lets say u haD A PROTOTYPE BOARD and had ddr12,000 with a conroe say 6400.crank away 600-700fsb u will eventually hit a cpu top ghz speed limit say 5.6ghz etc.ppl are calling these fsb walls,and others call them cpu max limits. .topped out to max ghz on silicone possible limits is the fsb wall or cpu max speed under any cooling\surrounding hardware.

i read this thread and fully enjoyed it.and im not hijacking any thread just think that certain model cpus have a ceiling limit -200temps , 2.1 volts to cpu,ddr 12,000 etc,killer mobo from h3ll.cpus have limits or virtual breaking points.and from the sound and some users in here,they hit them imo.saying no fsb walls is like saying 10gig is possible on a 6400....no it hit a cpu cieling max wall.

theres some amazing guys\rigs on this site btw,most amazing info i ever read.pleasure to be here.:)

kunnak your info is very usefull btw.

I just had an idea for boards that fail bsel manipulation. If you modify the bios and remove the microcode updates, the processor will be unknown if it'll still let it boot. In the event that it does boot then, it should follow whatever bsel is set to. This is a total shot in the dark, but was just an idea I came across while working on my bios. Note that I don't have a board which has bsel issues, so I can't test this theory. But maybe someone will take interest and try it out.

Not sure if anyone cares, but the latest DFI NF680i LT motherboard allows you to override BSEL from BIOS and boot at one of the predefined BSEL FSB speeds without modifying your CPU or touching the overclocking controls. I doubt this is of interest since I presume the whole point of this mod is to overclock CPU's on boards with no overclocking options. Anyway, just an FYI.

9/6 = 1.5 x 500 = 750 x 4 = 3000 mhz.

a 3 ghz NBCC is extremely high and in 90% of cases will not be bootable.

a CPU with a lower default multiplier has a far better chance at hitting 500 then a CPU with a high multiplier, which is why you see E6300's do it all the time, but never a E6700.

yes, the 4 meg cache will hold them back... but even a 4 meg cache CPU can hit 500 stable... so thats not the issue.
its the north bridge core clock.

a typical NBCC will not like going higher then about 2400 mhz before freaking out.

if your doing default multiplier, 2400 is enough for a 600 FSB.
but once you lower your FSB, you start to drastically decrease your CPU's ability to hit stable FSBs that are really high cause you greatly increase the NBCC faster.

---

This explaination fits the experiences I am having

I can run 375 x 8 but I cannot boot at 375 x 7! If u do the math the NBCC is running higher, thats the only difference. With the e2160 default multi is x 9.

Now I need a pin mod for the default multiplier.:shrug: They stopped that being moddable though.

Once a newer BIOS releases without the NIC issues, I will certainly be trying this on my E6600 which is most certainly more limited on this board then it was on my P5B Deluxe, mainly due to getting no POST at all if I have the memory set to anything but SPD.

So far as i'm aware there's only one P5W64, the pro one which supports conroe. Asus website appears to confirm this.

Without having to read all 260 posts, can someone confirm that the pin mod works and is safe to use?

Many a small synopsis.

Yes it works i have read this whole post over the last few weeks..
many people providing good info but you should take the time to read up.

Also
Its your Risk doing it..and its all ok providing you can boot this with stock vcore because if u cant and have to reset bios after Oc failure what then...?

works for my E4300 @ 266 FSB on :
1. DFI Infinity 975x
2. Foxconn 965
3. DFI Infinity DARK P965S
4. Biostar TF 965PT
5. Biostar TF P965

wont work with :
Gigabyte 965P DS3
Abit FP IN9 650i SLI

i have not try 200 to 333 mod..
but i'm gonna try it anyway..on my E4300 FSB wall (if it does exist) is around 400FSB..hopefully with 333 strap mod there's a headroom to push some more

Its works... I did it on my cpu.
It'll show E4300 1.8ghz @ boot
cpu speed @ 3ghz.
In bios, the lowest fsb becomes 333mhz.
have fun. :)

just did mod on e2160 from 200 to 266 seems to be working great.

You can probably remove the conductive material (if you use conductive ink) with some rubbing achohal if it doesn't go over well I imagine.

Great. Thanks for that ;)

With the rig in sign, could be useful for me to do 333 fsb mod? :confused:
thanks everybody

If you need more voltage, then you consider also doing a pin mod to the cpu to increase the voltage per this guide:

Hi Everybody,
I'm new and I've seen all the posts in this thread but I can't find an answer of my question. It is possible to make this BSEL mod on my Conroe E6400 with Asus P5K Deluxe Wi-Fi/AP and which pins I have to connect.
If You can, please send me some pictures.
Thank You!
edit:
If I make this mod, can I gain ferquency over 3.20 GHz, because now this is the max. of my CPU.

Have anyone tried this on a E2140 yet? and does it help you to break the cpu "wall"?

I can confirm the 1333 mod does work on the Abit FP-IN9 SLI using my e6300 :up:

ok thx for info alphaone..
but it doesn't work on 800 -> 1066 i,ve tried before
hope it work btw

has it improved your overclock or given you a higher FSB to play with?

I have not tried yet as I just flashed the beta 1.4 bios to try and get past 350FSB cold bootable but will let you know later today


These bios problems with mid range Abit boards is a 'kin disgrace :down: :mad:

i tried it on my Q6600 and it did not work...intel must have a different pin on the q6600 to bounce it up to the 1333 strap.

what the mod did do was really limit me from changing out of the default multi....as soon as i tried lowering the multi, it would not post...i checked for continuity between the two pads in addition to verifying the silver was not making any contact with the middle and surrounding pads....

bummer!:(

It made FA difference to my overclock because the bios is so rooted I cant get it much above 400FSB that is bootable and stable :shakes:


My last Abit board :(

I am trying but not getting it to work on my x3220 anyone have success with this one?

Is it possible to mod a Pentium 4 540 to the Xtreme Edition FSB (1066)?

that would be great! :cool:

do it

did anyone try to do the mod on a Q/X/E6XXX (1066->1333) on a P-35 board??

FSB Wall exists afaik on my e6400, I do not have more than the one chip, however, 6x 7x 8x, they all bsod at 463FSB, 460 is fine, tested on DFI Lanparty 680i LT, DFI P965-S, ABIT IP35-PRO, and GIGA P35-DQ6 at various voltages and settings, using different rams ranging from ballistix 800 and 1000 to corsair 1066 dominators and 1066 gskills... on all systems with several different rams the results with this chip are identical, 460 max FSB... the only difference is in the performance of the boards..

yeah, i tried it on my Abit IP35 Pro and it did not work for the Q6600...i could post and boot but my overclock was now limited...i could not get close to 500 fsb as i was doing before.

Yes, this mod can be done on any Intel desktop processor, and does not depend on certain model. But sometimes may not work due MoBo BIOS matters, like Asus.

could be but according to Kunaak, he said to make sure your bios supports 1333 processors and my Abit IP35 Pro was designed from the ground up to do that...i would think abit and asus would have the bios there in place when they sold them to do that very thing.

if i was to a wager on this, i would bet that intel caught on and changed the internal cpu registers of the newer revision cpu's to prevent us from upgrading the cpu to a 1333 bus.

It's no a requirement, just a recommendation. Or it just wouldn't work at all ;)
As for your idea - it's not so. The problem is not in the CPU. In my article I wrote about the BSEL mechanism. On the CPU side the only thing is to pullup to Vcc or down to Vss three (in case of LGA771\775) grids. They don't even have to contact to the grid. Only connected in the proper way in the socket. No connection. So Intel can't make any influence due to the mechanism of Bus Selecting.

The pinout on a P4 is different from a C2D isn't it ?

Wich pins do i need to connect?

EDIT// oke, i found out that jou need to connect BSEL1 and BSEL2 for 266Mhz FSB, is that correct ?

ok, i am following you with the pull-up or pull-down by making the connection...but couldn't intel deactivate those two pins/pads where there is absolutely no way to pull anything down or up???

No, it isn't different. I repeat - the Bus Selecting mechanism is a part of the MoBo. All the CPU does is connect the pins. And because the sockets for P4 and C2D are compatible (aren't they?) the pins must be the same. Otherwhise the bus would work properly only on one of the two.
Yes, all you have to do is connect BSEL1 and BSEL2.

They could do this on their MoBo's. But though the mechanism is made only by the MoBo, it can't by deactivated anyway from the CPU side.
So you can completely isolate the CPU grids from the socket pins and set them manually. After this will you believe? :)

ok...abit sticks it in my ear, AGAIN!:D (only kidding...very satisfied with the IP35 Pro)

Can somebody send a pic which pins I have to connect on my E6400 and will this mod work with Asus P5K Deluxe P35?
I ask You because I've readed all posts but it's no clearly is this mod working on E6400?!

So if I understand correctly:

If you want to go from High to Low, connect it to a Vss or connect it to a Low BSEL.

If you want to go from Low to High, connect it to a Vcc or isolate it.

Is that correct? And would isolating work if you want to go from low to high?

So a 266fsb cpu is L-L-L, if you want to go to 333fsb you could isolate BSEL2 to make it H-L-L, or connect BSEL2 to a Vcc. Would that work?

OK!...here's my question to all the experts on this!

why can't i take my Q6600, which is a 266 FSB processor, and JUST isolate BSEL2 pad on the cpu so it does not make contact with the foot pad contact within the cpu socket to make it go from low to high...won't that do the same thing as taking it from BSEL2 to VCC?

right now, for 266 FSB base processor...BSEL1, BSEL2 and BSEL0 are all suppose to be low resistance ( i presume grounded)...SO...if all i have to do to convert to 333 FSB processor is take BSEL2 to high...if it is grounded now, i am presuming that; isolating BSEL2 pad from the corresponding cpu socket leg should take it to high...CORRECT or NOT!?

On page 49 of Core 2 Duo processor, we can see that we are making a simple jumper between G30 (BSEL2) <-> J30 (VCC)

http://img64.imageshack.us/img64/5228/intel01zz4.jpg



On page 60, G30 means:
BSEL2 - POWER/OTHER -> Output

And on page 61, J30 means:
VCC - POWER/OTHER -> ?
http://img528.imageshack.us/img528/5223/intel03zc9.jpg


So, on page 75, I've found that VCC is an Input:
http://img70.imageshack.us/img70/3426/intel05hq8.jpg


And on page 69, we can se an explanation what is BSEL[2:0]
http://img70.imageshack.us/img70/5100/intel04ei2.jpg

and it points to Table 17 (page 30) which is:
http://img232.imageshack.us/img232/1880/intel06sd3.jpg
I can't see a possible combination to 333MHz, just 266MHz (Q/X/E6XXX) or 200MHz (E4XXX). Maybe just newer processors have it (?) :rolleyes:


So, this mod is simply make a jumper between BSEL2, an output FSB frequency selector, and VCC which is a simple power pin.

reading Intel's Xeon 5100 Series Datasheet I've found that on page 19:

In the pga days, it's be nail polish to insulate or just yanking a pin.

To make a high resistance into one of low resistance, one can either link it to a bsel of low resistance, or link it to a ground (vss).

It looks like from this technique as posted by op, it's been determined that you can link up a bsel that's originally flagged as low to a vcc (power) to bring it to high. I'm still thinking of the phenomena behind this myself, but it looks like it'd essentially be causing a relative resistance as seen by the motherboard to be high and thus be the same as isolation of the land/pin.

its not gonna work. but you can try it, it won't kill your chip thou.

tip:
if you don't want to mod your cpu, you can mod your mobo!;)

i tried the BSEL2 to VCC but the mod did not take...checked the continuity and it was good....could be the bios not supporting the 1333 bus but i cannot see why since the IP35 Pro specs says it will support 1333 FSB processors.

maybe the boot block had it missing from the original shipping bios...since trying the mod and failing, i flashed to a beta bios, including the boot block area, the flash to the boot block gave me improved performance...only way to find out now is to rip the board out of the case...UGH!:D

what does the motherboard mod entail?

I just did it with a #2 Carpenter's Pencil on my lapped Core2Duo E6600

FSB is still 1066. BIOS v1801

Hello!

I've done the 333 mod with a graphite paint on my E6400 (wall @ ~510, under DI ~520 so I hoped it will help even a little) and nothing happened - Commando was recognising 266 all the time {1001 & 803 BIOSes used, unfortunately shortly before BIOS 1302 was shown I removed the mod}.

Here is the picture:
http://img520.imageshack.us/img520/3...mod1333sf1.jpg

I want to try again, with Celly 420 this time :), so I suppose I can do the 200 => 266 mod then maybe the 266 => 333 mod - I will try.
My question is what do You think about that graphite paint - maybe I must use something different? :shrug:
From what I've read about that graphite it shall do well but the result was far from my expectations...

Edit: Now the picture is working :)
