I received my second celly 1.2 yesterday from essential computers. It was another malaysian chip. (retail) Since I ruined the first one removing the IHS, this one still has his hat on!! 8^)
I wired vid1 to vid2 to give me up to 1.8v on my ST-6. I ran the voltage all the way up initially and went for 1600. I got a post, but no windows. Backed down to ~1500 and booted into windows. I then reduced voltage to 1.7 and played some wolfenstein. ( our server: 216.242.107.101:27961 - The Lion's Den) Worked out ok, but had to go to work so I backed it down to 1.5v and 1.2 gig so the family could surf and game while I was at work. Gonna try some burn in action to see if I can get it stable at 1.5 and then make another attempt at 1600. I will keep you guys posted as to my success or lack thereof. :D

You should be able to do around 1550 at least @ 1.8v highly stable. You should run prime on it to check for maximum stability. That is the kicker for me it seems. Also the IHS on my second celery was concave too so I lapped it. Thing is though you may void your warranty if you do that. I was wondering if something did happen could one color the copper underneith silver with silver pens? If you lap it like I did you will find a copper layer that is well copper colored and is very noticable. Maybe we still have a workaround if the silve pens work for coloring it to make it look silver if you decided to lap it. I wouldn't try it though without knowing for sure. i am crazy though in doing stuff like this. I know I gave many here advice not to lap it but after I saw how concave mine was I had to do soemthing about it. I know I lapped my old PIII .13u IHS and it had a much thicker silver layer and I didn't need to go down as far. Actually I didn't need to lap it at all as it was perfectly flat unlike my second celery. I never did see copper on that one so I would have been safe if I had to RMA. Best find out how good of a fit is under the HS before pulling out the sand paper. And then ask your self if it is worth it. That is my advice from now on with these .13u chips. I have killed to many and it is not getting worth it any more. The OC'n bug is driving me nutz:burn:

You all won't be dissapointed if I cool it for awhile will ya?

I think I may have found someone local that wants to buy it. My electricity coming into my apartment can't handle it. I didn't insulate underneith the cpu and when I pulled it apart I had icicles hanging off the transistors on the back side of the chip:eek: I know the chip was cold but o well I could run 1700+Mhz with it but after awhile of a load it would kick out. I bet when I hit 1840~1870MHz with my old chip it would have been the same way. I would not have been able to run prime for very long cause of the bad juice. I got an ups but it was ironically worse then. It kicked out of prime alll the way down to like 1620MHz. I could run 1600MHz on 1.625v all day long but it still was too much and I figures for only 50MHz more it wasn't worth it. When I get a place that has good juice then I will hit again.This place has the worst juice I have ever seen.

OKay this thread should really have been called part three. I ruined another chip in the middle of this project (again) when removing the spreader. I think my new method is the way to go, but I am out of dollars to spend trying. I have been gripping the sides of the perf board the chip slug is mounted on. (the one with all the pins sticking out of it) Then I use pliers and just twist the spreader off. Works pretty good, but does take considerable force. I was using pliers to hold the perf board and unfortunately for me, they were not aligned perfectly and one of the teeth on the jaws damaged the edge of the perf board. I was just in too much of a hurry again. ... sigh..... Anyway, had I clamped it with just enough force to hold it straight using a smooth surface against the edge (machinists vise comes to mind) I think I would have been successful. I can't afford to try it with the current chip. Unless of course people want to contribute to my paypal account incase I fail. hehe Just kidding!!! My research must stop here till the chips get cheaper and I get over my $220 worth of mistakes. The new chip is singing right along at 1.5 gig, but I have the voltage a bit high. (1.75) I am gonna lower it when I get home tonight. It is hot in my case (40C) and my chip was showing 47C. Guess it will be ok till I cool the case better. I hope my mbm is set up right, I really did not have an easy time getting the temps to work till I read some threads on it. I will see what max speed I can achieve tomorrow and post it to this board and to the CPU database. If anyone tries the twist off method for the spreader and has success (or not) let us know here in this forum. I just don't like the razor blade method. I am glad it works for some though.

Happy Overclocking!!!

Wow dude, I have removed two of these spreaders now in about 1 minute or less with a very thin razor blade. I would not do any twisting or anything of the kind on the IHS. I know someone who did that with their PIV and when they twisted the IHS it came to the side and chipped his core. If you know what you are doing there is no reason to cut traces on your chip. There is no way you can cut traces if you keep the razor blade completely flat two. I have removed the spreader twice now and when I was finished the base and traces didn't have a lick of scratches on them. None! I am not sure what you are doing wrong but maybe I should hold a school for this technique. When I say thin I mean really THIN MAN. I should take a measurement of the blade to tell you all how thin it has to be. I still advise against this though. If you do get the IHS off I will say the second time I did it I made a shim from clear packaging tape and layer upon layer with the middle cut I finally found the sweet spot where the core had optimum contact as also protecting my core. The botom of the HS and the shim are the same size so it there is no room for gaps or anything if done right. I had a hard time before this celery getting the HS to fit right on the core and actually chiped the edges pretty bad but the thing still ran. Now I will never chip my core and ever have to worry about making awesome contact with the core cause it will always be. This is what intel should maybe do cause with this method there is no way you can not get perfect contact with the core and the other nice thing is it is semi permanent and will never move around on ya when you are trying to get the IHS to sit nice on the core. Maybe I should sell Phillipine OEM chips with the IHS taken off and tape shims added to them so every one can enjoy the OC'n goodness of the .13u core. I would bet every Phillipine made chip without the IHS would probably hit 1600MHz on 1.65v or less. As has been shown some are hitting 1600 MHz at default with the IHS. WIthout it they may do it undervolted. Wow that would be sweet. ALl this makes me wonder why intel did not just keep on with the PIII line and scrap the PIV. It seems most OC'rs in the know stay away from the PIV. At HWC where I am a member with over 2000 posts not one single person owns one on those chips. The only thing as of late that I have noticed about the PIV is that with SSE2 optimizations it does kick but in photoshop. But in everything else it seems to fall behind. I don't use photoshop.

One thing I did this time with my ALPHA was add a layer inside the HS so it would make excellent contact with the core with maximum pressure and it has helped out big time.

If I remember right at 1.675v I could run my chip at 1516MHz with a core temp of 35 idle and 39 load. Ambient was at 22.5deg. C.



I just did a measurement of the razor blades I am using to do this and they are 1/96" thick. Anything more than this and I would guarentee you will not have success. This is the cleanest and safest way to remove the IHS. If done right you will not scratch, indent, or bend the IHS which if the chip has a sudden defect you can return it by gluing it back on. As for the base with the traces and stuff, if done right it will not leave a scratch on it either.

This twisting buisness I know has already chipped the core of one PIV but it was still okay. I would assume that the smaller fragile core of the celery would also see the same fate in alot of cases.

If you come in at a angle with the blade it will cut a trace no way around it. Common sence tells you that. If you come in with the blade flat there is no way an sharp part of the blade will touch the traces and if for some reason you can not get the blade under the IHS then you stop there. You don't put the blade at a angle it is as simple as that. It is kinda like if you can't get your ram to go in the slot then you may have it in backwards right. I am sure it has happend to a few of your:D It has me. If it does this I do not start pushing harder I simply take out the ram and check out what is holding it up and everytime in my haste I have had it turned around.

Everytime I have went in with the absolute middle of the blade flat on the base(NOT THE SHARP PART FLAT?????????????????) into the corner o fthe IHS it has easily went right underneith the IHS. There was not gap you can really see but there was enough of one or my razor blade made one since the corner has a small up lift aboutthe same hight as the razor blade when flat.

Thanks for all the detail in your post. If and when I get brave enough to try it, I may try your method first. But for now I am getting 1.5gig and that is good enough for me for the moment. I just had some bad luck and did not take my time. I still think the twist off method is viable and could even be enhanced by making some cuts on the edges of the glue using your technique to minimize force needed to twist off.

Yeah dude I don't advise people to do this anymore as I fried one chip cause of booting the chip with too much vcore and no core contact with the HS. None! If you do get the IHS off you need to have the HS for sure touching if you are around 1.8v otherwise it may blow like mine did. I never thought intels thermal shutdown feature would not work without the IHS at the higher vcores. Alas it does not. One thing to watch out for.
