DDR3 RAM

[Surveyor]

Hi Surveyor,

Hope you have a great day ahead!

For the last 3 hours, after leaving office I have tried out 6 re-fitting the H60, the TG-1 grease almost used up I guess.

You mentioned before may be the thermal distribution inside the chip itself is sort of polarised, no matter how much more or how much less I use, the TG-1 helps, I come to that later; but the core 0 and core 3 polarization is like a constant.

I applied more grease to my first few attempts, and finally managed to strike a balance between the thickness of the coating and the holding idle temperature. It is slightly higher with thicker grease, but the temperature reaches a peak of 72C running Prime95 and that's the highest it goes. With thinner coating, the initial temperature is lower only slightly though, but when it comes to Prime95, it goes as high as 78 to 80C!

After 7 attempts, here is the result I have got




Also, i think we are the luckier folks in that we got a pretty good overclockable chip, but it never goes beyond 3.6GHz. At 3.7GHz, it boots but one of the cores failed the Prime95 stress test. At 3.8GHz, it boots but 3 cores failed the Prime95 test I bet if i continued, the last core would have failed also.

So that's all, the final verdict is 3.6GHz, that's all I have got. Stable for 20 minute so far and the highest is like 72C, is that temperature acceptable?

3.6GHz with temperatures in the low 70's is fine.

I would just leave it at that and enjoy using your PC.

Bad news is I was in a hurry to do the refit, and I broke the front hatch of the left panel of my beloved 600T!!!!! Well the panel still fits to close but opening it require some manual adjustment because the front hatch is no longer operable!

Oh.....my HK$ 1,280!!!

You could alway try contacting Corsair about a replacement side panel or latch.

I doubt it would be cheap to send a side panel to Hong Kong though.

If all else fails get the super glue out.

Another update, I fired up strike fighter, frame rates are not good, still in the low 20s but the CPU temperature went up to 58C only, not as bad as I expected.

Tomorrow, when I return from office, I shall check out Crysis Warhead and Far Cry 2 to see what's the temperature is like.

I think my next plan is the i5 and a good motherboard. If you hear or happen to know any good mobo, please let me know!

A bitter feeling is the broken hatch of the 600T, it's only a few days I bought it...and I have to live with the inconvenience for the next couple of years may be more...my Praetorian has been in service for 5 years since 2006...

I also doubt if Corsair will actually care about this!

Super glue will not do, because it is a small part of the latch which is plastic...anyway...pffffff...its like dropping $200 out of that $1,200 you know...

Do you think with this spec that I have now, DCS A-10C Warthog will run smoothly with 30+ FPS and all settings max'd out?

No experience of that game myself.

Some user experiences here and here.

I played around with it on the other day while I was o/c'g the Q6600.

surveyor,
at long last I have made it
i manage to bring the temperature closer...

You are right, I have to rotate the cooler by 90 degree anti clockwise and then every thing has changed!

I'm glad you got there in the end

I think I've made it at long last folks!

I refitted the H60 Cooler on the CPU again, this round it works!!!

I did say the cooler would need refitting

 

[Peter Tsang]

At the beginning I didn't want to re-orient the cooler's position. As you can see in the picture showing the case inside, the P5Q Deluxe's CPU socket is surrounded by 3 sets of heat sink. Only the right hand side of the socket has no heat sink and allows more room for the twin tubes coming out of the cooler.

That was the original position of the cooler which proves to sucking badly! A difference by 10 degrees and no matter how much grease I put in it still sucks badly.

The cooler is now rotated by 90 degrees counter clockwise. Unfortunately, due to the structure of the twin tubes I can further rotate the cooler by another 90 degrees counter-clockwise, the tubes won't sit comfortably that way. I bet however, the temperature will be even better if that position is possible.

Anyway I am VERY happy now. I can have it running at 3.8GHz to a maximum of 77C when Prime95 loads up all cores by 100%. Previously, it was above 80C.

One thing I would like to ask, is that because of the DDR2 RAM which I have got, they are 400MHz, what happened was that no matter how much voltage I pumped into the CPU Voltage, the system just wont run stable, when I up the FSB by 2MHz??? I mean it runs my favourite flight simulation games and Crysis Warhead well at FBS=420 but not 422??? I even injected 1.55v to the CPU Core Voltage but that still wont do!!??

Do I have to manually input say 2.10v to the DRAM Voltage in the BIOS to make it work at 422? I bet if this voltage works, I can furhter make it running at 4.0GHz
