1333 FSB Mod, Confirmed To Be Working By Me.

[Ace-a-Rue]

where are your specs so we can see your cpu and other hardware?

This worked perfectly on my MSI P6N Diamond board with the Q6600 (B3 stepping). It didn't give me any additional headroom for my overclock, still stuck at 2.73ghz on that POS board. On a happy note, the same CPU runs at 3.13ghz on my Asus P5K Deluxe.

You do get a 2-3% performance boost by having the 1333mhz bus vs 1066mhz, according to the review here:
http://www.xbitlabs.com/articles/cpu...duo-e6850.html

They show the identically clocked 1333mhz and 1066mhz CPUs and the 1333mhz wins in every benchmark by 1-4%. I really can't explain why, I mean there's a bit more bandwidth there, but we're not talking anything earth-shattering. You'd be better off to overclock everything to 1333mhz and get the benefit of lower latency and more bandwidth with your overclocked memory than just running the higher FSB alone. I guess to each his/her own though.

Clock the same cpu to 333mhz and drop the multi to the same as the native 1333mhz FSB cpu and it'll outperform the E6850/E6750/E6550. It will run at a tighter chipset strap, depending on the board.

is thier a 800 or 1066 fsb pin mod for a pent 805 d ?? would love to do it !!

[denden]

has anyone try pin mod Q6600 to 1333 on DFI P965 and had oc benefit?

[Khapz]

not worked on my asus commando bios 1404 + e43

[denden]

it is proved my Q6600 is successed to pin modded to 1333 and workable on DFI P965 dark, still testing on any benefit out of it.

not worked on my asus commando bios 1404 + e43

Very nice 4300 will go to heaven ^_^

My E4300 does 9x333 no bother at ~1.4V and has been to 390 (Vc=1.55, Damper Enabled, Vpll=1.7, on a Peltier) but wont boot with the 1333 BSEL. On P5K BIOS 414 so that may be the cause...

Mod is working on my E6400 + Biostar TP35D2-A7.

sweet. ok i just thought of another little problem... check out post #12 here http://www.xtremesystems.org/forums/...d.php?t=111510
the pin mod described shorts a BSEL H and a BSEL L to create two BSEL Ls. according to wikipedia an open-drain output should work like that (ie if you have a string of open-drain outputs on a single line then the voltage line will stay high until one of them is brought low, at which point the line will become low). but there have been quite a few mods done by shorting a BSEL L with a Vcc to bring them both high, some of which worked. they might have just worked 'despite' the ground in the circuit because the Vcc pins overwhelmed the small circuit, since they're power supply pads, while the BSEL pads are for a low current sensor circuit. perhaps what needs to be done to bring a BSEL from L to H 'properly' is to insulate the pad, then paint over it with conductive paint, so that there's no ground/BSEL L in the circuit. i think some people have already picked up on this idea from what i read in other threads. does anyone who had no luck the first time feel like trying it again with an insulator + Vtt ;D?

Interesting.

I have a 200FSB Intel E2140. I have to switch 200->266. So I have to change BSEL1 from H to L.

Is it correct in your opinion to link directly BSEL1 and VSS, or do you think it's better to apply previously tape on BSEL1? Or other manner...

Thank you. (i send you also a PM).

hmmm... I wonder... will it be possible to mod the 1333mhz chips to 1600mhz once the 1600mhz chipsets/bios' come out?

You OCed a Dell, right on!

i have a E2140, all is great, but my ram can't handle my FSB anymore. the lowest memory divider on my abit ip35-e is 1:1, if i jump to 1066 or 1333 would i get a new set of memory dividers.

[ziddey]

1:1 is the lowest the p35 supports. and 1:1 is only in 333strap. 266strap starts with 4:5. 200strap starts with 3:5.

[jkabaseball]

ok so i'm done with until i get new ram

memory divider or strap is a NB or MCH controlled issue...it will be separate to your FSB bus or system bus which is controlled by your CPU.

the IP35 should avail you to two 1333 mhz memory straps...those are 1:1 and 1:1.20...the next two are 1066 memory straps shown in the below image.

Indeed, 1.8 -> 3.0 isn't bad for a $200 machine

Check out my desktop, slightly scaled down from the 5200px wide it is. I know, the right monitor's image is off a little, but ya can't tell when viewing it.

[First of all, sorry for digging this thread up.] Scratch that, I just realized I'm digging a thread with the last post made 4 days ago... lol

Ok, after reading the whole thread, I've got some questions I have some questions I would like to have answered, if you don't mind.

The first one has to do with the subject discussed in post #326 (here), confirmed working a couple of posts after. So, my question is: could the "VTT" mod provide a workaround to the boards that don't recognize the "VCC" mods (most notably, A LOT of Gigabyte boards)? Or that is really a BIOS problem, not a mod one?

Now, for the other question. I have a 775i945GZ ASRock board (there... I know, only for a small server, and that's what it's doing right now), with 2GB 533MHz DDR2 memory (maxed out... ) and an 805. Custom cooling with a Thermaltake Sonic Tower plus a XL2 Noiseblocker fan. I have seen here some BSEL mods to try out. I'd like to try them out, but but I don't know if 1) my PCI/PCI-E lock would like the 166 setting (the guy from the last link had a problem with an 865G-based mobo) and 2) the mod would be recognized by the board.

Also, do you think the 200MHz "lock-friendly" setting would also need the Voltage mod?

I don't mean to highjack the thread. If you think I should start a new one, please do tell me.

Lastly, could you please point me out (or make one... ) to a "BSEL mod" guide for Socket 775 CPUs, with pictures for EVERY strap? I have found a Voltage guide somewhere, but BSEL mods only appear for 1066 and 1333MHz, and you have to dig somewhat hard for them...

Thank you in advance.

Cheers.

Miguel


P.S.: Oh, I almost forgot. What would happen if you modded a board to, say, the 1066MHz setting (so you don't have to mod the CPU), and dropped a 1066MHz CPU in it?

Gross... why would anyone "do it" with a pencil?

[Trox]

I did Vcc pinmod to my E6400 and its working!

[nullface]

Is there a pin-mod for E2140?

800 -> 1066
or
800 -> 1333

[Ace123]

interested in seeing a 1600mhz mod.

Asking me? Or just saying "i wont to see a 1600 mod"
