Please help! Pin mod Xeon 54xx!
Is it possible to pin mod 54xx to 1600mhz FSB?
I want to do mod 5410 2.33 to 2.8ghz and use for WCG.:D

Bump, and MM? Not my area of knowledge....but I'd like to know.....:p:

You need a 5400 chipset to do 1600fsb.

[sierra_bound]

BSEL pins 2 & 1 need to be taped. Chips may not boot if you have a 5000 series board.

[linhvndiy]

So connect bsel pin 1 &2. Is it correct? Can you draw for me?:D

[sierra_bound]

No, you need to cover those two pin pads so that they don't make contact with the pins in the socket. I use thin electrical tape for BSEL-modding. You need to cut very small pieces to cover each pin pad. I would use a very sharp exacto knife to cut the pieces and then use the tip of the blade to deposit them on each pad. Then press down a little with your finger to make sure each piece of tape is sticking to the pad. Since BSEL 1 & 2 are next to each other, you could also cut a bigger piece of tape to cover both. When doing the mod, please make sure you have the processor oriented properly. In the diagram, note the corner that has the gold triangle.

If you have a good eye and a steady hand, it shouldn't take that long. Both pin pads are near the edge of the processor, so that makes it a little easier. Good luck.

[linhvndiy]

Thanks a lot. But please help me more. Please guide me through real cpu picture.:D
I have CPU 5410 and Supermicro X7DWN already, but only FB 667. Do you think it will work with FSB 400 and 667 mem?

[sierra_bound]

Yes, DDR2-667 FB-DIMMs should be fine. I believe the board you have has a working divider. There may not be a setting in the BIOS. But someone else using the same board and BSEL-modded Harpertowns was able to run DDR2-667.

Unfortunately, I don't have a real picture to show you. My modded Clovertowns are crunching right now.:D Movieman might have a photo. Again, you just need to cover those two pins pads with insulating material. You can use electrical or masking tape. If you have two CPU's, the mod must be done on both processors.

Sierra has it right to the letter... Just a tiny piece of electrical tape over those two pads and your all set.
If my old eyes could do it you will be fine.;)
Just take your time.

Here is a pic of my X5340's pin-modded from 1066 to 1333 FSB (2.4GHz to 3GHz)

This is the BSEL2 mod only (G30) - from what SB is saying you need to do the pin immediately above (H30) on yours too:

My friends, is it easy like that.:D
Thank you all.

[Movieman]

Yes,that easy..
Good Luck!:up:

[[XC] serlv]

So, I'm curious here.

Why does the OP have to do H30, also.
Is that for something above and beyond the "notch-up" from 266 to 333? Like for 400 ( on the proper board... )?

[sierra_bound]

I don't have the technical explanation. The diagram is for 65nm Xeons. What I do know is that another person covered those two pins and got a 333MHz Harpertown (E5440) to run at 400MHz. CPU-Z also renamed his chip a 5450.:D

I was looking at motherboards @ newegg , and saw listings for Intel 5400 and 5400A.
What is the differences between the two?

[[XC] serlv]

Anybody know anything, or heard anything, good about the Asus 5400 chipset mobos? Like this one? (http://usa.asus.com/products.aspx?l1=9&l2=39&l3=299&l4=0&model=1988&modelmenu=2)

[sierra_bound]

I believe Intel refers to them as 5400A and 5400B. The latter is the one used in Skulltrail. It supports the 1600MHz bus.

Not all 5400 boards officially support the 1600MHz bus. Here are a couple of examples.

Tyan i5400PW (http://www.tyan.com/product_board_detail.aspx?pid=560)

Tyan i5400XT (http://www.tyan.com/product_board_detail.aspx?pid=562)

Both use the 5400 chipset. But only the first board officially supports the higher bus speed. According to Intel's comparison chart (http://compare.intel.com/pcc/showchart.aspx?mmID=33088,34447,33085,33084&familyID=5&culture=en-US), both chipsets will run the 1600MHz Harpertowns.

[linhvndiy]

So, tapped bsel 1 or both 1&2?:D
Any way i will try both.

[linhvndiy]

Tapped Bsel 1 not work. I will try 1&2 now.:D

[Zanr Zij]

Finally Successfull tapped BSEL 1 & 2 ! 5410 2.33GHz@2.8GHz

[linhvndiy]

Confirmed bsel 1&2 works.:D
I will test boninc tonight.:D

[karl_eller]

Out of curiosity, do they need any more voltage to run at 400 FSB as opposed to 333 FSB?

Eller

[Movieman]

The answer is "Maybe"
Depends if the chips will run an additional 500mhz at the defalut voltage..
Iknow on the clovers I could go from 2660(10x266)to 3157(9x351)at the same stock voltage(1.35v) but to get beyond that stable I would need more.

[sierra_bound]

Confirmed bsel 1&2 works.:D

:toast:

[STEvil]

your chips are is 1333 by default so you just need to tape BSEL 2 probably.

[linhvndiy]

Oh, thanks. Do I have to remove bsel 1?

[STEvil]

If its working then obviously no ;)

[[XC] Jaco]

I'd like to know if there are pinmods to bump the stock vcore up a little ?

My X5420 is stuck ~ 3015Mhz .
402 x 7.5 is all this chip can do at stock vcore. (1.192v)
I'm running 430 x 7 , so it's not the board or memory. I'm using an Asus Z7S board and Transcend 800 FB dimms.

Would love to do 430 x 7.5 = 3225 Mhz . 1.25v-1.3v is all I need.

[STEvil]

vcore pinmods should be the same as 51xx/53xx cpu's that have the same default VID's.

[jcool]

Bad luck there Jaco :(
My 5420's can do 430 with stock voltage, guess I got lucky. But you can Vmod the CPU to get higher, I can't do anything since there is no mod for VTT.
But the BSEL mod to FSB400 on mobos that don't support FSB adjustemnt should be almost guaranteed to work with any CPU up to the E5420.

[topboy]

Just found this thread....very usefull

Could SB or MM confirm if Bsel1 on Pad H30 would need to be taped/covered on my 2 Harpertown Xeon E5450 to achieve 1600 FSB Default. Current default is 1333 i think.
These are sitting in a skulltrail so i think the board is capable of 1600.

Thanks in advance.

Why don't you just go into bios and set FSB to 400? What's the benefit in doing the BSEL mod here? I don't see one except extra work... BSEL modding is for mobos w/o fsb adjustment.
It is also likely that you will need to raise the Vcore to rech 3,6Ghz/400 FSB, something you can only do via Bios with Skulltrail. So go for it, we wanna see some results! :)

Because most server boards don't have FSB and vCore adjustments? And most CPUs will do an FSB jump (ie 266 > 333, or 333 > 400) on stock voltages.

Eller,

read his post, he says he's on a Skulltrail ;)

Ah, right, I missed topboy's post. I was looking at linhvndiy's and Jaco's posts :p:

[linhvndiy]

Hu hu, Please help me again.
I just have xeon 5440 and want to mod it. But i taped bsel 1&2 , it was not work. It's seem i taped wrong pin. Any one have real picture of modded cpu.
Many thanks.

[linhvndiy]

Any one can help please?:D

[sierra_bound]

The mod may not be working because of the clock speed. 8.5 X 400 = 3400MHz. You may need better cooling or more voltage.

[jcool]

They should at least post at FSB400, whether it's stable or not. Hmmm...

[linhvndiy]

It's not boot at fsb 400mhz, still att 333mhz. So i think i made something wrong. Please help.

[linhvndiy]

I found : I did correct mod. But can not run at fsb 400 with supermicro x7dwa-n, and tyan 5400. So is this mod looked in bios?

[Martijn]

Could it be possible that the board doesn't support 400fsb?

The X7DWA-N will boot at 1600FSB BUT ONLY if you have DDR2-800FBDimms.
With 667 FBDimms and a BSEL modded to 1600 cpu it won't boot at all a s the cpu speed is conflicting with the memory speed.
The opposite way will work, DDR2-800 with a 1333FSB cpu as the board automatically puts in a divider. I have seen this myself.
Get yourself some DDR2-800's and then your OK..

[STEvil]

667's may work at 400 if you have ones that are capable of doing 800. Most are not.
