A Simple tweak make fsb 1333 into 1600 on 45 nm

So is read as a simple tweak, converts fsb 1333 @ 1600 on processors from Intel 45 nm out so far.

Coolaler the site shows images in the following

QX9650 as you know has multiplier free, but comes manufactures in default to 333 x 9
Tweak the purpose of this is to make the mobo to take micro and 400 x 9



So we should just plug this contact that marks the red circle for the mobo we take fsb as 400 x 9



Here we have the result, remember that the QX9770 brings fsb 1600 and its speed is 3.2 GHz being manufactured for now the only micro FSB 1600 put up for sale by intel ... until today, thanks to this we managed to tweak our motherboard to take our QX9650 of 3.0 ghz @ 3.6 Ghz (400 x 9)



As seen in the image, particularly in the bios this Order, so no traps or anything, actually believes that the motherboard has a micro FSB 1600



We saw in windows with the cpu - z to check once more that tweak is effective



After having checked and confirmed spend about 30 minutes orthos to verify stability (if there was a mistake or contacts problem before 30 minutes error is inevitable) as it is completely normal



45 nm others

E8200

Repeating the same process we see as our previous bios believes that our E8200
(8 X) gives us 400 FSB, from an original speed of 2.66 @ 3.2 Ghz



It is found again with CPU - Z that the change is real.



E8500

You know the same procedure that all previous micros and ready, we believe that our bios E8500 has fsb 400



Again it is found with CPU - Z that the change be effective and that's all



Ladies and gentlemen, we have seen a reason to die more to buy a motherboard with more new chipset "that our P35 ".

Assuming it is 333, Wouldnt this make it a 3.4 then?

Grrr...

So the 2.8 has a 7 mulpt, 3.0 is 7.5 and 3.2 is 8? Is that just the standard spec on processor?

Hmm, looks like it might!

Time to crack out the sandpaper AS5 and some tape...

And at 100% duty on the cores, i never saw temps go above 45ºC.

Not that I've heard of but to be honest I haven't played around with the AMD's since the socket A days..

Point, but it has been discussed quite a bit here.. Just search BSEL mod..

There is no benefit on a board that has that ability in the bios.


\Exactly, this came about for the dual socket boards that don't have OC ability in the bios. It is pretty safe. My clovertowns have had this done to them for over a year now and no issues.

all fine man, not problem!

Do Intel (somethig like DG33TL) boards accept the BSEL mod? I know that Gigabyte boards do not from first hand experience.

Isn't it one pin?

Two



A Simple tweak make fsb 1333 into 1600 on 45 nm

Does this method work to take a 200mhz fsb chip to 266mhz? or does it need the conductive pen method?

I want to try it on the e2160 in my Dell server



A Simple tweak make fsb 1333 into 1600 on 45 nm

dont see the point of this unless u cant enter BIOS to overclock it, then it is a nice mod



A Simple tweak make fsb 1333 into 1600 on 45 nm

Sometimes influencing/chaning the BSEL setting also changes the default strap setting for the NB. That means that on some boards you'll reach higher fsb speeds with CPUs that have a higher default FSB. That's why the mod even can make sense on boards that do have adjustable FSB in BIOS.



A Simple tweak make fsb 1333 into 1600 on 45 nm

wait so this mod is almost the same as going in the BIOS and manually changing the FSB higher? when doing this mod, would you have to increase the vcore also for more stability?

Not likely. Each BSEL mod is different, depending on starting FSB. You should search the specific mod for it. Search the forum, there are plenty 200>266 FSB BSEL mod threads available, and also 266>333 (and before you ask, yes, at least theoretically you can make a 200MHz FSB CPU work at 400MHz just by doing a - rather major - BSEL mod).

Well, it's just about the same thing, altough you can get a strap change with a BSEL mod you might not get doing a regular overclock, and that strap change could allow more OC room. That's not very common, to my knowledge, though.

As for the vCore issue, it really depends on the chip. There have been reports of E1xxx. E2xxx and E4xxx to go wild on the FSB (266+, sometimes even more, especially with the E1200) with stock vCore. I've also read reports on Q6600 G0 chips being perfectly able to boot at stock voltages, even after a 266>333 FSB BSEL mod. My guess is these 45nm parts wouldn't even flinch by changing the FSB to 400MHz, but that really depends on the chip itself.

In related news, it's good to see someone already messing around with the BSEL of new chips. Which reminds me... Isn't 1.6GHz like the lowest CPU speed Intel wants people to use? I mean, that's the lowest speed you can get these days (SLFM-enabled notebook models and 200-series Celerons aside, of course), which would in turn mean Intel could very likely fully downward unlock their 1600MHz FSB CPUs and still remain with VERY powerfull parts, albeit even cooler. And if SLFM (which halves the FSB speed) would be added to those parts, then we'd probably have sub-5W parts on idle, and some of them could even be made to be sub-15W regular desktop ones... yikes!

Cheers.

Miguel
