I did the large FFT (maximum heat, power consumption,some RAM tested) and it just freezes with 4 cores.... i'm curious if you could give that a try with the 4cores (you don't have to obviously), reason i'm asking is that I had 4cores enabled and tried the other prime95 Small FFT (maximum FPU stress, data fits in L2 cache, RAM not tested much) and i thought that it was passing on 4cores... i will try again....
I like the undervolting and may try that to reduce the heat when i make the sig rig my main pc... Looks good!

Radio, if you notice we both (mem and I) have aftermarket coolers with the 300... Mine fits really well, in fact it is real close to the top fan which really gets the heat right out the top of the case... i love it!

Ya I will run some P95 for ya, but I have a feeling it may not do well, for what ever reason I have issues with P95, at least I did when I was overclocking past 3.8 and beyond. But as I had said before, I think it's my ram that is the issue. I RMA'd 4GB already, and waiting for that to get back, and then I will RMA the other 4GB.

According to ADATA's spec sheet for this particular ram it can run between 1.8v to 2.2v, and it is recommended to run it at 2.1v for 1066, or 800 @ 4-4-4-12. I think I might try and tighten the timings up a bit more on the ram, I currently have it at 5-5-5-15 @ 1066MHz @ 1.95v...

Do either of them require removal of the mobo to install? I like how the stock fan just has that bar that goes through and clips onto the ring around the cpu, very easy.

The DarkKnight does not require you to take the board out, and I agree with MrAMD_Fan that it fits the 300 just perfectly. It is close to the top exhaust, and if you put the fan on the bottom of it, and use a side 120mm fan on the side panel, it feeds cool air directly into it. Just nice indeed

I think it was Hondaguy that said running the ram at 800 with tighter timings yields much better results than the 1066 at the looser timings... I can say that is true in my experience as well.... You don't have to run the prime95 for me... i am going to stay at the dual core and work with that... i need my pc to be as stable as possible as it will be my main pc when it is all tested....

Fantastic. I will be picking up a DK ASAP then! I need to pick up a side intake fan as well then, because that does sound like a good plan. Thanks again for the info you two

Memnoch_thedevil, not sure if you did mention this already but were there problems with the memory when everything was at stock settings? Issues with P95 may indicate an unstable overclock. Did it pass stress testing at stock speeds? Did you verify with memtest that the memory was in fact faulty/failing? What number tests did you run in memtest?

Good luck

It failed memtest inside of Windows, not the regular version of the test. With everything at stock and the memory at 800 it was fine, but at 1066 it failed. Until the new ram gets here, I am going to just keep working on the undervolt/overclock phase, and then when the new ram comes I am going to test it first via boot memtest to make sure it is good. I just got the video card back today, so hopefully the ram will be next and soon.

For whatever the reason P95 doesn't like me. I can run OCCT and IBT all day long with no errors, but I have always had issues with P95. I have had success with P95 before, I think my longest run before I shut it off was 5-6 hours or so, can't remember, I have the results on the PC somewhere.

I am going to be running it tonight when I go to work, so I will post those results in the morning.

But like I had said before, if i can encode 7 movies to DVD format at the same time that my wife is playing a flash game in firefox, while streaming a movie to my TV in the living room, I don't really think there is a stability issue

Also, a 20 pass IBT on max is pretty reliable as well. That is the latest one I have passed. Perhaps it was my OC originally, I will know for sure when the new ram arrives, because the only thing left that could be causing stability issues when heavily oc'd is the processor..so kind of a process of elimination hehe

I'm trying the undervolt right now.... 3.2ghz (200x16) @1.216v (cpuz) 1.25v set in bios... p95 has been running for almost 2hrs now.... so we might have a winner! Temps are only at 33c at full load...my ambient temp in the room is around 76F.

k i got my new case in.
i reseated my cpu with MX-2 and overall around 6C lower temps. i am happy

mx-2 huh? I'm thinking about picking up some of that or some ocz freeze with my DK.

its nice
i made the mistake of not waiting for the alcohol to dry off completely after removing the old stuff. it was a pain to get on. when i got it finished it was on a little thick. not too thick. but it oozed a little out the sides. any worries?
