prescott 3.0 on ic7-max3
 

Hi all,

I have a strange problem!I just got me a prescott 3.0 (was looking for the 3.2, but they where out), and I lapped the CPU like I do with all.

I was maybe to confident, that the damm thing would work, as I know you kill your warrenty with lapping. (but it saves you a degree or so)

I have a killer watercooling systen, white water, 3 radiators etc. with my 2.8 northwood, I had no problems running it at 3.5 Ghz, at nice 35 degrees (full load for 2 hrs)

I updated the bios, so it would support prescott, put the cpu it, placed my whitewater on top with some AS5, and the damm thing is hitting 46 degrees! (idle) I heard they are hotter, but this much?

Well, Normally I would not worry about it, but the damm thing won't even boot into windows. (on clock speed, and even on bus speed of 100 mhz)
Max voltage I tried was 4 steps up.

I remounded the thing 3 times, and then put mu old 2.8 in. All 3 times not even windows, and with my 2.8 directly without problems.

Is there a problem with the IC7-Max3 and prescott? What else could be wrong? :shrug:

Or do I just have bad luch and bought a broken CPU. (damm I should have tested it first) :mad:

Looks like there is Prescott support.

You sure there are no sanded metal particles shorting the pins out?

Try washing the CPU in some isopropyl alcohol and then give it a go.

thanks for the link, but I got the latest bios IC7-MAX3 BIOS 15.

I guess I'm gonne need some one with one other prescott ready mobo, to see if it's the CPU, or my mobo not supporting..

It almost looks like it's having a heat problem :D if I leave it on for a while, even my bios hangs :)

but it's strange, I don't see how giving a shortcut would result in unstable performence. OC would, but I'm not even at that point :cry:

Well, looks like 245 euro down the drain.......

next CPU I'll sure will test prior to lapping!!!!!!!!!

good idea... ;)

But seriously, why lap it for a mere degree or so?

Wouldn't removing the heatspreader itself be better? Especially since you're going to void the warranty anyways.

I believe the heatspreaders of most new Intel CPUs are epoxied to the core.... so that would be kinda worse.
