Ok, A friend bought an E1200 some time ago and is running it on an Asus P5KPL-VM (G31) motherboard. He has 2Gb of the Patriot 4.4.4.12 Ram but the board has no ram voltage options so I left it running at spd settings.

The overclocking/voltage options on this board are very limited but I manage to get it prime95 stable @ 2Ghz (1.6Ghz default), FSB is 250 Ram is at 834. pushing the chip any further fails prime 95 as the ram is at it's maximum with out the required voltage boost.

He purchased a conductive pen (£10) and we did a BSEL Pin mod to take the default FSB from 200 to 266. we replaced the chip into his board, no boot. Tried a Cmos reset just in case, problem persisted . To make sure the pin mod was working I striped down my PVR system (Asus P5K-VM) and swapped out my E2160 for the pin modded E1200, it booted at 2.13Ghz, a quick run of Prime95 proved that it was stable. Pin modded my E2160 and tried it in my board, booted at 2.4Ghz tried it in the P5kPL-VM no boot.

So it looks like the P5KPL-VM will not work with Pin modded chips. Unless anyone has an idea of something we may have missed?
 
Your statement is totally incorrect.

most Core2 based processors will overclock to at least 25% without a bump in voltage. (in a quality intel based board)

EG q6600 G0 2.4Ghz to 3Ghz = 25% overclock, no voltage adjustment required.

E2160 @ 2.7Ghz 50% overclock no voltage required. (infact it is prime95 stable at 1.2650v Coretemp reports vid of 1.3250v)

There is evidence all over the net of >25% overclocks on stock volts.

I have done a proof of concept, as in both chips run fine with just the pin mod on a p5k-vm with no other changes required.

I am of the opinion that perhaps the P5KPL-VM is working on the processor ID and when it is faced with the board "requesting" a bus speed that is greater than the Id it perhaps triggers an error and the board will not boot.

I also have a suspicion that his board may have a problem with 266Mhz FSB chips perhaps through a fault. I will discuss with him if he wishes to test this theory by installing my Q6600 (@ stock) to confirm or disprove this theory

That depends. There are CPUs that won't run high because of their VID. So what's the VID on the E1200?
 
Hehehe, Save me, Shadow!

The over clock kids are out in full force!

"I swear I just needed to change FSB to 400, RAM to Sync, VCore to 1.40 and manually enter in my RAM info!"

That appears to be the new Motto! ::chuckles.::

And now all these boards are coming with seamless strap integration and manually entered numbers. (which it then applies the nearest divider) And they cause all sorts of hidden trouble. Where one used to just swap FSB to NB straps, you can no longer manually do this, so you getta change the QDR a point at a time until it applies a new strap!

(And while it's on a bad strap, or other setting it doesnt like, it will pass just about anything, for instance the Small ffts, but there will be all sorts of weird errors happening, or performance degradation.)

The Blend test gives it away, because no matter what you do, the threads fail one after another really fast when having this problem! However, no one knows it's there, they just get the problems, lol!

The guy over you has it mostly right. If you defeat VDrop and droop totally, you'd get like 500-800 Mhz of speed increase. But in reality, your "no voltage" increase is really quite a large one.

Since VDrop and droop spec can be up to .115 volts, that means my 1.2000 VID chip can run stock at 1.0500 volts or a lil lower with zero problems. INTEL just adds headroom, because they dont want a single one to fail within 3 years, or you get a new one!

So remove this, and load the processor up at 1.2000 Volts, the VID, and I get from 2.4 Ghz, up to 3.2 Ghz for free. (supposedly.)

Same with people looking at VID, defeating it, and then saying they Over clocked on no more voltage, or less. Well, VID isn't your EXACT NEEDS, VID is what you need for stock, with full vdrop and droop applied. (And obviously they would have a little extra room for failure, because they DONT WANNA GIVE YOU A NEW CHIP.)

So for all you OC with no voltage increases out there! yeah right!

Yeah, hehe! my rants and raves. BUT, the seamless junk I have been thinking on writing a small warning about it.

The damn thing looks like other **** is causing it! So all the newbs are convinced it's something else, when it's the strap bull shiznit, BUT the newbs will have no clue, and describe stuff that could be 5 other reasons, lol!

And then you try to correct for 5 other things, which takes forever, and all it was was the strap was wrong for that FSB, or it didn't like it, or whatever!

So far, ALL 4 NVidia boards I have had share that problem! No Front Side Bus to North Bridge strap selection anymore. Just enter what you want, and it'll get it as close as possible.

To bad, even after all this time, your computer is a dumb as a 1, and a 0. Some SMART human had to come by later and determine what all the 1s and 0s mean. Not the computer. It just runs that mans calculations over and over very fast putting the 1s and 0s together.

And now it can select your strap for you? I mean, come on, there are 3 straps that will work with 800 Mhz Ram, lol! 0, 1, and 2.
266, 333, 400.

Since we know it can't count to 2, lets make sure the human can no longer switch it there! Well, sometimes you need it at 400 Mhz, lol!

Blahblah. I hate typing. How goes it over there?
