New Daneb 4.0 Overclock

post #1 of 12
Thread Starter 
Good Evening,

I just managed to get my new amd 965 in the case and overclocked to 4.0GHZ using the multiplier. Voltage is roughly 1.4 depending on whom you ask.

I'd like it to stay as a 4.0 processor for ever but I'm concerned about temperatures. I've reapplied the $3.49 white radio shack "heat sink compound" and might have made it worse by a degree.

Running with the cooler master hyper 212,


42C idle
62C-66C+ on benchmarks and prime95 load.

Using prime95, the temperature seems to just go up and up. I stop it at 67C.

prime95 will stay stable for the time it's on.

Is this the best I can expect from the cooler/processor (CM 212 and 965) combo? Do you think I messed up the thermal paste application again? Should I go down in speed to cool it off, or up in cooling power some how?

Thanks for your insights

yea and ur temps are way too high 67c the safe max temp is 62c

so slow down?

or could i have a cooler attachment issue?

should i expect 965 be to stay cool at 4 GHZ with this kind of cooler?

It does seem stable, though I can't push it hard for more than 10 mins or so rolleyes.gif

u should back it off untill u can get a better cooler because i dont think the 212+ cpu can handle the heat

How are you cleaning the heatsinks and applying the thermal compound, and what are your case and ambient temperature?

sorry for taking so long to get back, i work weekends.

Thermal paste:
I've been wiping it down, and the second time i used some gun cleaning solvent too and that seemed to work really well. I will reseat it one more time and i will use small drops on each of the heatpipe grooves, then apply heatsink in twisting motion to processor, screw in place. Ambient is roughly 76-80F and i've been keeping the sides off.


My current situation is it won't boot after I adjusted the HT to 2600 via the multiplier and all i did to stabilize was add 0.1v to the mobo's nb.

No biggie to fix, but i'm wondering if it's really worth it to chase the HT overclock. I understand many report a memory-bandwidth bottleneck clearing up, but i have slow ram. I am using 800mhz ddr2 so if the HT link is open to 2000mhz, how is there any bottleneck in my case? The memory won't run at 1066 speed.

I guess I may not understand how HT links the ram, but if the ram is 800mhz, HT is 2000, seems like lots of room for the ram to do its thing, so what are we (or other slow rammers) gaining by increasing HT speed?

Are you sure that it is the motherboard's Hyper Transport? The C.P.U.-N.B./uncore would be the R.A.M.'s link to the C.P.U.
H.T. does not give too much of a boost, and it might inhibit performance, so 2.6GHz H.T. might not be worth it.

Once the heatsink is installed, I would not move it; its pressure might be enough to spread the T.I.M.
What is your heatsink?

heatsink: cooler master hyper 212 http://www.newegg.com/Product/Product.aspx?Item=N82E16835103065

right i mean the North Bridge. My settings have NB voltage, NB-CPU VID, and I only changed the NB voltage. either case. let's replace instances of HT with NB in previous post. A NB at 2000 when memory can only do 800 mhz ddr2... where's the bottleneck? Why go to 2600?

My C2 Deneb does 2.2GHz uncore/C.P.U.-N.B. with D.D.R.2-800C, and it raised the memory bandwidth, so yours might show an improvement.

You should be adjusting the C.P.U.-N.B. voltage.
You should leave the H.T. at its defaults unless overclocking shows a benefit.

You should apply a thin line of T.I.M. across each pipe of your 212 Plus, but cleaning the old T.I.M. via isopropyl alcohol and a coffee filter might help before reapplying your heatsink and T.I.M.

ok thanks for the thermal paste tips. While installing the cooler I noticed I may not have tightened it enough so this time i tightened it a lot more. not sure if it's on all the way or if I can go further (there's a springed screw right on top of the cpu that seems to apply heatsink pressure to it)

I am now idling at 40C and loading at 62-63C. I am prime95 stable for 30 minutes or so at 4.0 Ghz and 1.4v. NB is 2200 at 1.2v. thumb.gif

I stopped prime95 at 30 minutes because now my cpu fan is making clicking noise at high speed. ugh. it's always something.

but it seems to be working! and I think 62C should be considered acceptable load temp.

btw, there was no difference in cinebench cpu score from 2000 nb to 2200 nb. I'm hoping its true that 2200 mhz nb will "stabilize" my 4ghz. I prob should use a memory benchmark but that was the only score I had pre-downtime.
