Before lapping give some ceramique a try and see where it gets you.
I can't seem to find any ceramique around here (In Malaysia), though there is MX1. Will that do?
Also, try running your OC with the 9x multiplier with a fsb of 300 instead. Should fetch you a 2.7ghz OC with less heat from your Northbridge and stock vcore should be plenty.
1- Well, I agree with Pax2All: lower your FSB and set multiplier to 9: there will be a whole benefit on your MB heat production, you'll maybe get some higher frequency and no voltage increase
The reason I actually set my FSB to 350 was to run my ram synchronously at 700 (667 oc-ed to 700). I thought running it synchronously was faster..
Edit: Oh, and remember TAT and Coretemp 0.95 figure e4300 temps based on an assigned tjunction figure of 100c not 85c(CT build 0.94). When figuring temps keep them proportional to the tjunction figures used. 60c load figured with a tjunction max of 85c is roughly equivalent to 71c load (73-75c actual since theres a 3%-5% difference with the real world conversion) figured using a tjunction max value of 100c.
Um.. I'm not too sure I understand this at all!
😳 So does this mean that my max temperature while under full load on TAT can reach up to 70+c?
2- Be sure your vcore is fixed to 1.325v and not set to Auto, as most MB will increase the vcore when you increase FSB.
3- I find your idle temperature really high, TAT load at 66° maybe a bit high for that speed, but some E4300 really run hot. What ambiant temperature are you running? Also control your case temperature that should be Ambiant +/- 3 to 5°C in a really good ventilated case. Some confined cases can reach up to 15°C difference from ambiant, thus a 15°C increase in your CPU temperature. I'll put a digital (or normal) thermometer inside the case, and let it some 15mn on load with TAT. If it's the case, don't look further: ventilate your case
4- If none of the above applies to you: you could fell on one of those really concave chips or with too much compound between the chip and its IHS.
IMPORTANT: Before lapping your CPU, check with a razor blade if it is really concave. No need to lapp it if it isn't.
And really, the most important part: you're running a low overclock at low voltage. TAT is creazy: nothing will ever generate so much heat. Rather use Orthos: 5-7° lower, so you'll be around 58-60°C Orthos. And remember that also no application will produce as much heat as Orthos, you see my idea? You should be really safe if you don't intend to push your E4300 further in speed.
2. I guess that's okay then, since it's at manual currently, and with no additional voltage.
3. My ambient is around 29-30c. My case is a Lian Li A16... and after loading with TAT for some time, temps in the case (measured using a digital multimeter with temperature measurement) is around 31-32c.. I guess that shouldnt be the problem then huh? My exhaust air is also arnd 31-32c as well.
4. Do you think I should try using MX1 TIM? I'm using the TIM bundled with the TR U120 right now.. could that be the problem? I was thinking that if the heatsink was really effective, it should itself be rather hot if the proc is measuring at 67c dont you think? I mean, right now its really cool to the touch even when the proc is running at 67c. Could it be that the heat isnt transferring to the heatsink fast enough?
I guess the logical next step would be to test and see if the surfaces are concaved... and maybe get new TIM...
I'm not really worried that my CPU would exceed its max temp now. I just feel like pushing this proc just a lil further. I was hoping to reach (350*8 ) or even (350*9) though i think the latter is a bit too optimistic.
Thanks alot for your help, guys!
