[OFFICIAL] Phenom II X4 9x5 OC Club - Page 526

post #5251 of 5692
Hi all, like T3TSUO, im new to Oc, i get my new system (my sig) this week and i want to squeeeeeeeze it. ive oced today to 3.8ghz raising only the multiplier. also ive made auto oc in bios before, proc speed was 3411 mhz, and voltage 1.45, i though its high for this speed (based of what i could read these days - not much) and i lowered to 1.425. im using turbo V app doing all this stuff. i made 45 min prime 95 test, screens below. what i can raise / lower, please help me what i concern most is temps, since here (spain) right now in my room is 30+++ C
thanks in advance.

How much LN2 did you use for 12h?

Care to post a screen shot?

I was joking...I was only at 6.75ghz for ~20min and I probably burned through about 4L of LN2 while doing it. I don't have any screen shots, but if you want to see pictures of it you can check out the August Ice thread here: http://www.overclock.net/overclock-n...e-extreme.html
(the pictures are towards the end)

i fail so hard. got

Phenom ii 955 BE C3, Hyper 212 stock thermalpaste, pushfan only @ 100% speed when stresstesting with prime95/occt:

At anything above 1.4Volts gives me ~63c, ambient is ~22 +-1c.
And 3.6ghz @ 1.4Volts with 53-55c got error in prime95, this means i must go higher on Vcore right? which brings me this 63c , regardless how little i increase. ive remounted/reapplied the cooler twice now with line-between pipes-application twice and filled those gaps between pipes too...
I use multiplier and Vcore only, is there another parameter that i should care about CPU/NB VOltage, could it stabilize if i only used multiplier?

My goal is 3.8ghz at max ~55c when stresstesting... but i will never get that... fun OCing.

You might be applying too much thermal compound and that's why your temps are getting high with only 1.400 volts. If you are applying too much you are creating more of a insulator between the CPU and the heat sink, all you need is a small drop of thermal compound in the middle of the die the size of a uncooked rice grain or 5-6mm long. You don't want to apply to much or you'll get worst temps.

antec formula 5 guide says: apply very thin ply of compund on heatsink and, as u said, small amount of paste, then applied all over the cpu. i did like guide says and i think my temps are ok?? is this method correct? sry for my horrible english

If that company says that's how they would like you to apply their thermal compound, that means they have found that by doing the steps they say provides them with the best results. I have always found that the "spreading method" applies too much thermal compound on the CPU and has the risk of leaving air bubbles which is bad for thermal heat transfer. One method that Arctic silver 5 mentions is that you apply thermal compound, to the heat sink than wipe it off with a clean lint free cloth, (do not use a cleaning solution on it) they call it tinting the heat sink. By doing this the thermal compound fills in, all the microscopic imperfections in the heat sink. It should look as if the bottom has a greyish tint. Than apply a small amount of thermal compound the size, of a uncooked rice grain to the CPU on the AMD processor. Do not spread it as when you apply the heat sink it will spread by itself, and the chance of producing air bubbles will be at a min. If you are happy with your temperatures I wouldn't worry about changing your technique, just thought I would tell you about a different way of applying your thermal compound.

Congrats on getting to 4.0ghz. What are your temperatures on the cores, with 1.525v at idle and on load.

Hey guys. have a question for some of the 955 OC masters

I can Hit 4.2GHZ on BOTH of my phenom x4 955 processors. 1.5250v and 1.55v for the other, and everything else set to auto, it can survive 24hr. is my board bottleneckin these chips or is that just the limit? AIR OC
