Need Help With Temps and Over Clock

[LiquidFlame]

Well I got my RMA?ed MB a couple of days ago so I decide to hook it up. I should first off say that I?m using a old GPU that I have (GeForce MX 4000 PCI) until my RMA?ed GPU comes in the mail, so the one in my sig is not in my rig right now. Originally when I did my first over clock to 3GHZ I had these settings with the following temperatures after running Prime95 for an hour:

Set FSB to 1333Mhz
link and sync RAM
Set RAM timings to 4-4-4-12 2T
CPU voltage = 1.35v
FSB - 1.3v
Mem - 1.9v
SPP - 1.4v
MCP - 1.525v
SPP-MCP - 1.35

Room: 75.7 F
Core0: 61.8 C
Core1: 61.4 C
Core2: 56.7 C
Core3: 56.8 C

As you can see, these temps were not that good, and I couldn't really figure out why I was getting such high temps. I decided when I was putting my motherboard together, I was going to go all out with the mod?s that I felt comfortable with. I lapped my HS and CPU, which came out pretty well. I also did the vdrop mod, and I replaced all the TIM on the mosfets and NB/SB which I have always done. Now the original temps that I had, I wasn?t too happy with so I was hoping the lapping would help. I ran Prime95 for about an hour with the same BIOS settings as above, and I got the following temps:

Room: 75.7 F
Core0: 65.9 C
Core1: 65.9 C
Core2: 60.39 C
Core3: 60.55 C

As you can see the temps got worse, and after about an hour, my computer crashed with a blue screen saying "Hardware Conflict, contact you hardware vendor". I have never seen this error before, so I?m not sure if it?s because of the crappy GPU I?m using. I have all my system fans running on 100%, and I?m really concerned that I may have done something wrong when I was lapping my CPU and HS.

I decided to go back to regular stock speeds, and ran Prime95 for 3 hours plus and I haven't had any crashes, these were the temps that I got:

Room: 77.5 F
Core 0: 55.44 C
Core 1: 54.52 C
Core 2: 48.95 C
Core 3: 49.05 C

I am using AS5 on my CPU, and I know the AS5 has a 200 hour burn in time, but I don't think these temps should be that high. Can you guys please help me with my temps. I?m not sure what I?m doing wrong. Thanks for the advice in advanced.

A G0 with a Tuniq as you have, running a Vcore of 1.35V (is this bios/idle/load?) and is OC'ed to 9x333 = 3GHz will see Temps in the high 50's °C to low 60's °C.

I have a G0 (VID 1.2875V) that requires 1.3750V (Bios set) to be Prime95 stable with small FFT on a Tuniq120 at 9x333.

The temps during load (per coretemp) were ~57°C across the cores with a load Vcore of 1.2800V (Vdroop is very high on my DS3L).

Your original temperatures were fine at 76F room ambient. Just fine.

I'm not familiar enough with the EVGA mobo -- I have the Asus Striker -- same chipset. Early last year, a friend and I had speculated and anticipated removing the copper heatsink "necklace" from the chipsets and mosfets, replacing the TIM with AS5 or a micronized diamond paste.

We're glad we didn't do it. Apparently, on the ASUS board, the TIM is part of a glue - just short of epoxy. You run the risk of damaging the board by removing the copper heatpipe cooler (and what I meant in first sentence -- I don't know what onboard cooling your EVGA provides, or what it looks like.)

You HAD the right temperatures, and probably improving airflow and case exhaust would've improved them. I have a B3 Q6600, and with a lot of attention to cooling with my U-120-Extreme, it was showing average core (TJunction) values close to 65C with room-ambient at 79F.

But this would mean a TCASE temperature of closer to 55C -- several degrees below the throttling point, and well within the Intel spec.

I just don't understand why I'm having so many problems just trying to got it to 3GHZ. My chip should be able to easily do that without any problems.
