prescott 3.0 on ic7-max3

[fhorst]

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)

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 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

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.
