1333 FSB Mod, Confirmed To Be Working By Me.

[__Miguel_]

The CPU has to be stable at whatever speed the pin mod puts it at, at stock votage. i don't think a pencil will work.

True, if you only do the BSEL mod. In case of this mod, your CPU must be stable at max FID (or whatever you set it through the BIOS) at max stock VID.

There are, however, default VID mods out there you can also apply at the same time.

So, in short, this is only a BSEL mod. If you need more voltage at boot, then you'll also have to search a voltage mod for your CPU. Just google for it a little, I found a list of all voltage mods for LGA775 CPUs a while back. You only need to know your default VID at boot (If you don't know, RMClock can tell you - that is, if you don't have anything else to tell you that).

my cpu is rock stable 3.26Ghz. My problem is where can i get this conductive pen. I live in Germany and i don´t really know the german name.Damn!! I will be happy if someone can tell me the name of one company that produces these pens. and from my calculations this mod will give me a 3Ghz boost without messing around so much in my Bios.

But is it rock solid at stock voltages?

[Shocker003]

Not at stock voltage(1.2). I need 1.38v for this speed and do i need to increase my chipset voltage too?

If not at stock voltage, then you'll need to use an additional voltage pin mod when you do the FSB pin mod, or else it won't boot.

How can i get around this fsb pin mod can you pls. give me some hints. and which company produces the conductive pen?

There is a company called "CircuitWriter" that produces conductive ink pens.

I have the same problem, since I live in Portugal, and modding material is not that easy to find (especially where I live). But from what I've gathered, you can either go for a conductive ink pen or visit an auto parts shop/mechanic and ask for the stuff they use to paint the rear mirror heating stripes (a.k.a. deflogger), which is called "deflogger paint" in english.

I'm sure you'll be able to find something.

Oh, one last thing: even if your motherboard can OC to 333MHz, you MUST make sure it has the BIOS to support the 333MHz strap. Otherwise, the CPU won't be recognized, since it will request a strap not available on the motherboard, which can lead either to the mod not working (no biggie there) or the motherboard not even POSTing with the modded CPU.

Cheers.

Hi,
i found where to buy the pen and i equally found out that my Q6600 can boot at auto vcore volt at 3.1Ghz. I order the pen and am just sitting and waitting for postman. As for my board it can support 1333mhz cpu fsb. Here is the link to a reveiw http://enthusiast.hardocp.com/articl...50aHVzaWFzdA==
Thanks to all that helped me in getting info about the ink.

You're welcome. That's what we're here for.

I've remembered something I wanted to tell earlier. It has already been said many times in this thread, but it's best to repeat once more: there are motherboards that can't be tricked into booting CPUs at different straps from the original ones. Gigabyte boards, for one, are a good example: they simply won't work with modded CPUs.

hi guys, i don't really feel like drawing up every possible pad mod (between 133, 200, 266 and 333)

but knowing all the BSEL pad settings (L/low, or H/high) for each front side bus you just need to know how to change a pad from L to H, or H to L, and you should be able to do any modification you like so long as your motherboard supports the new front side bus, with the disclaimer that it doesn't seem to work on every motherboard.

the images i've attached are taken from these 2 data-sheets:
Core 2 Duo and Core 2 Duo Extreme Series Datasheet
Pentium D 800 Series Datasheet - this is the only datasheet i found that describes the BSEL pads as open-drain outputs that should be raised to Vtt
and a little information about open-drain outputs http://en.wikipedia.org/wiki/Open_drain

i should mention that i have never done this mod myself
but this is how i would do it
this method is not the method that was posted earlier in the thread, but i think if the mod can work on your motherboard this method will work:

------
1) insulate the pad(s) that you want to change, perhaps with a little glue (superglue or epoxy), so it is totally isolated and can not interfere with the mod.

2) then, if you are modifying a pad from L to H, draw a trace over the insulated pad with a conductive material and connect it to a nearby Vtt pad.
and/or
2) if you are modifying a pad from H to L, draw a trace over the insulated pad with a conductive material and connect it to a nearby Vss pad.

a little tape can help with drawing the conductive trace, and probably also with applying glue if you decide to insulate the pad, eg:

------

the mod should be easy to remove with anything that'll dissolve the glue or conductive material that you use, eg meths or isopropyl alcohol (or you could manually scrape it off with a razor or sandpaper if you need to).

a method of doing the mod without a conductive-ink pen that i considered was to use tin-foil, or solder squished to a thin sheet (it compresses very flat with any pair of pliers), carefully shaped to fit on the correct pads and insulated with a little double-sided or single-sided tape where necessary. i was making a shape to fit on a friend's pentium d 805 to mod it from 133mhz to 200mhz with squashed solder, and it seemed like it would work ok if it was done precisely, and would be really easy to remove or adjust (but i never finished it cos he got a new CPU).

in many cases people didn't need to use any insulation, a BSEL[H] pad could probably be substituted for a Vtt pad, and a BSEL[L] pad could probably be substituted for a Vss pad. but the above method ^ is what i would try if nothing else works.

people have mentioned that the mod does not work with gigabyte motherboards, but i would be interested to hear if anyone has tried this on a gigabyte motherboard using insulation + Vtt, instead of no insulation + Vcc.

hope this helps
post your successful and unsuccessful methods and hardware

__Miguel_ can you give us some examples of boards that will run with a modded CPU? Which µATX board would you recommend for this mod?

I'm sorry I'll have to disapoint you on that one, Keen. I'm more of a book worm than an experimenter when it comes to OC and modding. I read a lot, but I don't have the money available to either test much hardware or be able to cope with the loss of the same hardware (all my systems are "production systems", so one missing is a REAL drag). Besides, my parents would kill me if they knew I took hardware near (or beyond... lol) the breaking point... They're an insane pain in the a** when I brake a plate in a kitchen accident, I don't even want to imagine to be near them if I break hardware because of an OC going south...

That being said, and from what I've read, it seems the X1250 chipset (on both boards that use it) doesn't understand BSEL mods, and also EVERY Gigabyte board. I have no information on NVIDIA chipsets. I've read reports of BSEL mods working with some Abit boards, as well as Asus (not sure which ones, though I think they were referring to P965 boards, at the time).

The most "BSEL-friendly" boards seem to be the ASRock ones, especially the 945G-based mATX versions. If memory serves me right, there has even been a report of a good 800-to-1333 mod working perfectly with one of these babies.

My general take on BSEL mods, though, is something like this: you either have a good enough board and can OC the hell out of it without BSEL mods (like Asus boards), or the board is not that good to begin with (like most mATX boards... lol), and the BSEL mod is mostly a moot point... ASRock mATX boards seem to be the exception to this rule. Unfortunately, they still don't have decent mATX boards, the most powerfull they have is 945G-based (still, they have Wolfdale support on that board already...), and even on ATX, they stopped on the P31 chipset... I'm hoping something G33 or G35 appears (hopefully, not devoid of RAM dividers, like most G33-based mobos...)

in many cases people didn't need to use any insulation, a BSEL[H] pad could probably be substituted for a Vtt pad, and a BSEL[L] pad could probably be substituted for a Vss pad. but the above method ^ is what i would try if nothing else works.

Thank you for the info, and hopefully this time there will be someone taking this information and actually VTT modding an 800MHz CPU with a Gigabyte board (like the G33M-DS2R ), and seing if that works... Ever since I saw your first post about VTT modding I was wondering if that would be the reason why Gigabyte boards don't accept BSEL mods...

Can someone PLEASE test hollo's theory (I've read reports of successfull VTT mods, and right here in this thread) with a Gigabyte board? It would be a breakthrough for many people...

Cheers.

Miguel

[hollo]

in the next few days i should have a chance to manually test the voltage on a stock BSEL[H] pad, and see whether it's at Vtt.
of course i'm 99% sure that it will be
but it'll be nice confirmation.

i would have done it already if i wasn't still a socket 939 guy

After reading a litte in this treat I want to see if I can get an Intel Pentium DualCore E2180 (2x 2000 MHz, 800 MHz Quadpumped) with the BSEL Mod to 1333MHz FSB. Just for fun of curse . But when I do so then I don´t want to use high-end hardware. Therefore the question if there is a µATX board you can recommend. Well Asus I will certainly never ever buy again. Abit also doesn´t count to my favs. and Gigabyte boards depart for this mod. So the question is if this mod works with an DFI Blood Iron P35-T2RL.

Does someone have experiences if the mod does work with the Blood Iron?

Well, if you want mATX, cheap and BSEL-mod friendly, then my guess is something from ASRock, since they are the cheapest non absolute c*** motherboards you can find. Actually, they are one of the best performing motherboards on some segments (like the 4Core1333-FullHD, RS600-based, which is better than the F-I90HD...).

But I digress. If you just want to BSEL-mod your way to OC (not a bad option, IMHO), I'll probably recomend the ASRock Conroe1333-DVI/H R2.0 (which is Wolfdale-ready). Check it here. It is dirt-cheap - as low as €55~60 here in Portugal -, has lots of add-on extras (including an HDCP-ready ADD2+ card), 4 memory slots (it you can live with only two of them, albeit also supporting 4GB of RAM, go for the Wolfdale1333-DVI, though the ADD2+ card is not HDCP-ready).

Keep in mind, though, that 945G/GC-based motherboards have VERY lousy PCI-E locks, so working at 1333MHz FSB, you'll actually have to set your PCI-E speed to 115MHz. Also, don't expect much more out of the board, though near 400MHz FSB have been reported (rather amazing for a 3-generations old chipset with lousy PCI-E locks and a maximum 1066MHz official FSB...)

IGP-wise, you get a GMA950, which is fully Aero-compatible. Don't expect to run anything else than the Aero desktop on the PC, though. 3D capabilities of the GMA9xx series is abysmal...

I'll have to tell you that ASRock is somewhat connected to Asus (never understood why, but some motherboard models are very similar). Would you mind telling us why you don't want to buy Asus anymore?

Hope this helps.

Cheers.

Miguel



P.S.: As I said before, I haven't BSELed any CPUs until now. If I recall correctly, I've seen a report somewhere of a BSELed E21xx running 1333 with an ASRock board, but I don't remember correctly where, so don't kill me if it doesn't work, ok?

[[KI]Keen]

Hi. Asrock is the subsidiary company of Asus. My co-worker and I sell computer and we had sold about 30 computers with Asus-boards some time ago. It doesn´t took long and a lot of boards (more than 20; not all the same model) died. Also some Asrock boards we sold died. On most of the boards some parts gone up in flames. After this desaster we decided to sell Asus boards never ever again. Now we sell boards vom Gigabyte und MSI for workstations. For gamingsystems and overclocking I recommend and sell DFI boards. The new Asus boards may be better but I don´t care anymore about Asus and Asrock. DFI FTW!

Maybe I try the BSEL Mod with an DFI Blood Iron. But I first look around if I can find some other boards which may be useful for this mod.

Well, that surely sucks big time... I've had some bad luck with an Asus board as well, but I have a P4P800-VM still going on to this day; also, I've had a 775i945GZ suffer a short-circuit (connected an HDD the wrong way), and appart from the HDD and a memory stick blowing up, the board is perpectly fine.

I believe Asus and ASRock make very sturdy boards today, so I'd ask you to please take another look at them.

As for DFI boards, the BSEL mod is really not necessary for them, as it isn't necessary for OC, not even for strap changing, in some cases...

Cheers.

Miguel

Sure I know that the Mod isn´t necessary to OC a low end CPU when I use a DFI board. I want to see if I can push the CPU to 1333MHz without the help of a good OC board. Like I sayd its just for the fun of doint it .

I've had some bad luck with an Asus board as well, but I have a P4P800-VM still going on to this day;

I also had a P4P800-VM in my media pc. It killed 2 Kingston RAMs. My Mom has a P4P-800SE and everything is fine until now. My dad has the the second Asus board in his computer after what? The first on died! But now it seems that the second one (Asus P4P800 Dlx) will also die. The NIC already has died on this board an an now it doesn´t find the DVD-ROM drives

Maybe I let him buy an E2180

Keen

[__Miguel_]

Well, that's a very bad luck indeed, Keen. My P4P800-VM is still working with my brother. He told me he thinks the IGP probably killed one of his monitors, but I don't really believe that.

Apart from that, only my P5B-Deluxe had a problem with hibernation only an RMA could fix (read: new board). I sold a perfectly good P4C800-E Deluxe that never caused me any issues.

Ok, but I digress. On topic again, for what I know, ASRock boards are the most likely you'll have to accept a BSEL-mod. DFI boards are for OC maniacs (you guys know it's true... ), so probably they'll accept them too - though in this case it would probably be easier to set "333 strap" and "333MHz FSB" in the BIOS, letting everything Auto, and be done with it... lol BSEL modding is more complicated than the DFI BIOS (and those are pretty complicated already... )

I've never really heard anything about MSI boards accepting BSEL mods, not sure why. Oh, right, I have a very bad feeling every time I hear that acronym. My brain just goes "move '*MSI*.*' > NULL" (I got the DOS notation right, didn't I?). My brother had a very lousy experience with a MSI P4 board a while back, so I said "no, thanks" since then. Later experiences with the same brand yelded the same results, so...

As "non-mainstream" brands - other than ASRock -, I have no information whatsoever.

It would be nice if there was a thread with information about which boards supported which BSEL mods, no?

Cheers.

i did the 1333 FSB mod on my e6300 last night. My board is ASUS P5B. My board got stuck in an endless cycle of reboot/shutdown before post/reboot etc. im using the 1605 bios, which is supposed to support 1333FSB cpu's. Removed the mod and it is working fine again. Not sure why its not working.

Modded CPUs are different from "upper-strap" CPUs: the first ones are asking for a strap they don't usually requiring. From what I've gathered (and I'm actually guessing from those findings), it seems some boards simply take the strap the CPU requests for granted, and boot acordingly (as most ASRock boards seem to do); others actually seem to compare requested strap with expected strap, and refuse to boot when those two values are different.

That is, for me, the most logical thing happening. Other options are some boards only acepting BSEL mods if they are "VTT mods" (see some posts earlier), but that has not been tested until now; or, of course, something being wrong with the BSEL mod itself.

Thanks for your reply, i figured as much, but was not sure if it was specifically board or bios issue. As for the VTT vs VCC methods for this, I did actually first do the VTT mod and it didnt cause the FSB to change. I then did the VCC mod and thats when i got the endless rebooting. Essentially they are almost the same signal, one pulls up to vcc (vcore) or to VTT (VFSB), which in most cases are relatively similar.

[__Miguel_]

As I've said before, I'm not an OCer myself, since I can't afford it.

However, I do read a lot, investigate on my own about other people's findings (hmm, I'm defining "bookworm", but what the heck... lol), and also make "educated guesses" based on what I see and read.

That's a very long statement for "eh, I might be utterly wrong", btw...

If the VTT mod didn't work and the VCC mod caused reboots, try the VCC mod once again. I've read reports of people having troubles with that mod, just to find out the mod was not properly done. The conductive ink's conductivness may be lacking, or the bridge may be missing some small part that makes it behave like that. It's worth a try, I think...

Cheers.

Miguel

[hollo]

interesting, i thought after reading Timbosan's post -
"if it's a board that won't respond to a BSEL mod (but sets the FSB from the the microcode or similar instead) then Vtt wouldn't do anything, while Vcc might provide a voltage that's off by 100-200mV, causing reboots."

maybe

i've been looking at the asus p5k series, and just found out what the voltage reference option does - it sets the Vtt with respect to Vcc via a ratio. the ratios are pretty big, i thought Vcc and Vtt were a lot closer.

normally the open-drain circuit on the board would sense a voltage drop over an internal resistor when connected to ground or a BSEL[L] pad, no voltage drop over the resistor when connected to a BSEL[H], but i dunno what it would sense when connected to a voltage that was higher than BSEL[H] (although evidently it is detected as a BSEL[H] on some boards)
