My NF7-S got fubared. Need help figuring out what.

[WoundedWallet]

I used to be able to push my fsb to over 440MHz and my cpu to over 2400MHz, but now the whole thing is screwy. I can't even leave the cpu at default and the memory at SPD and I get the funky two-tone beeps (indicating memory problem).

The stripped parts are:

Mobo = NF7-S v2.0 - bios 1.1
CPU = 1700DLT3C-JIUHB
RAM = 512MB Corsair PC3200LL (tried all slots)
HS = SLK-900 + 92mm Zalman
AGP = ATi VIVO 64MB (1 fan)
PCI = none
PS = Enermax 435W
HD = 1
CD = 0
FD = 0
Case Fans = 0 (but case is open)
Northbridge = original HS+Fan
Southbridge = HS(old 486 combo with fan disconnected)
USB/1394 = none connected
Speakers = none
Ethernet = nothing connected
Case wires = Only PowerOn, Speaker and Reset connected

My last experiment before the crap was to push the memory to 225 with very lax settings (9-4-4-2.5), just to see if it could go there. And it did. But could I've ruined the chip by trying this?

- Or maybe ruined the memory controller(wherever that is) by trying to run it synched at that high fsb?

- Or is it that little temperature probe that I attached next to the CPU bridges that is frsking things out? (note that CPU is not overheating, and I haven't had time to take the probe out to see if it gets better)

The last time I looked at the CPU there was some dark hardened liquid around the core. Is something oozing out of there or is it the AS3 melting?

Whatever it is, it doesn't look good. So outside suggesting to take the probe out(will do tonight), is there anything else that I could do to pinbpoint the problem?

I don't have another RAM stick to try(only a ECC, which doesn't work).

But I can try with another CPU, an old 1400-Tbird, which I can't overclock but I could check the memory speed with it.

All suggestions are appreciated. Thanks.

I don't know if this'll help you, but my 2nd and 3rd RAM slots suddenly went disfunctional after I changed my power supply. Tried each of my RAM sticks in the 1st slot, and they worked fine. My suggestion, get an RMA from Abit. They reasonably quick.

The dark hardened liquid might just be the sealant that's normally present, and it's usually mostly on one side. The CPU at the left side of this photo sort of shows it.

Such purty colors!

funny.. I tought I had replied to this post already....

Anyway, mechBgon that is exactly what I meant. Here is a photo of mine now. The shinny stuff on the lower left of the core seems bigger now than whatit was last week.

But I may not have any problems anymore. I'm on my third test with no beeps. I'm now at 2200MHz and 400MHz and no beeps

I took the probe out, reapplied AS3, and re-screwed the HS. Any of these three factors could've been the culprit.

I'll try now at 2400...

-------------------------------------
And It went thru fine!! I have this feeling that I didn't tighten the screws well enough last time. It is the new thing for me, I've always used clips. But maybe the probe was interfering somehow. In anycase, I won't be placing the probe over there for a while now. I'm plenty happy with 2425MHz@441.

Thanks, and sorry for getting so alarmed so fast. I'm so happy with my new chip that it freaked me out to seee it go away so fast.

Thnaks again.
