If you were overclocking your old chip, you'd want to reset your bios or adjust down your overclocks since the new e8400 should only get max of 1.35V or so.
I had an 3200+ and a FX55 clocked to the same speed and ran all of these benchmarks and they basically came out the same. The FX series are the biggest ripoffs that the cpu world has ever seen.
Maybe your cpu and/or your heatsink aren't perfectly flat thus getting bad contact.
Go ahead and try other temp monitoring programs like Everest Home, not sure if Coretemp would be compatible with a P4.
reapplying thermal paste is a must if you haven't done so in a while or are using stock thermal paste off of a stock HS.
Can I ask what temp monitor you are using?
I have a e6600 at 3.33Ghz now and there aren't much things that I can't conquer with this chip and had a Q G0 in my hands to use, but I couldn't since it wouldn't give me that big of an advantage unless you are heavily into music and video encoding and decoding.
What the heck? That's weird. My version has a drop down box between the "Priority" and "Additional Information" that let's you choose core 0 or 1. I run two of them and select different cores on each. Maybe my version is an older one. I have to go home and check.
I got a 44G as well from MWave shipped from California. Anything over 3.4GHz was difficult but at 3.4GHz @ 1.475GHz, with Tuniq Tower, I am 7 hour dual orthos stable. The temp dropped 3 degrees this morning so the paste is curing so will try again for 3.6 tonight.
The 667MHz RAM can take your cpu up to 3.33GHz without any OC on the RAM. It should go up to 3.4GHz easy. It is new generation ready at a 1:1 ratio.
If you are overclocking though, just go with a 800MHz pair, at least.
If you aren't planning to overclock, then I'd suggest any of the brand names with 667MHz speed. Corsair, Crucial, Kingston, OCz, GSkill, Patriot. Go with CAS 4 instead of 5, if money permits (I have a feeling it will be permitted). :p
What is your cooling method?
I am getting the Mwave one later on tonight so it's looking good. Some mentioned that the 44G are duds but you've just proved otherwise.
Depending on the RAM Oc'ability, on a 1:1 divider, we're looking at 2.4GHz to 2.7GHz for your e4300. The e4300 on average tops out at about 3.0.
Check out Tom's charts to see the difference between a e6600 and a PD 3.0 to see the huge difference.
Enable EIST in the BIOS (should be default) and when idle, the system will throttle the cpu multiplier to 6x. When using cpu power, then it will jump back up to 9x.
You can't run dual channel with 3 sticks except if you have a special AMD board (S939) that came with 3 available slots where you can put channel one 2x512 and channel two 1gb.
Anyhow, your channel 1 is 2x1gb and second is 2x512.
I just installed the e4300, Tuniq, DS3 Rev 2 F10 combo last night.
The initial temp in bios for cpu was at 16-17C, but the kicker was that my cpu fan wasn't even on! (I didn't check the temp AFTER the cpu fan turned on <got it turned on by connecting it to the sys-fan connector> since I...
Picked one up earlier as well and it is infact OEM with a year.
I am waiting for my DS3 and Tuniq Tower and will get this baby going. I don't know if I should keep the Geil PC8000 2GB at CAS5 or get some 667 RAM to overclock to 800MHz.
