Is this normal?

Hi All,

I've done a modest OC from 2.66 to 3.20. Bclk to 160 on a x20 multiplier. Memory (XMP) x10. IOH volts to 1.3v and CPU reducing to 1.25v. Running OCCT for a few mins on large data set I'm getting temps in the mid 80's which isn't good.

Can anyone tell me what I should try next to keep the temps down (CPU voltage?)

TIA
DK
 
Thanks.
i7 920 2.66 CPU, GB EX58-UDR3 r1.0 mobo, 6GB Corsair 1600 XMP RAM, Zalman fan with huge copper heatsink, Coolermaster tower case, Nvidia GTX470 GPU.

I'd like to get as close to 3.7ghz as possible.
 
Looking at those temps you are not going to get much further. Should'nt be that high for such a small overclock though. What actual heatsink is it? Have you tried reseating it? Have you got decent airflow through the case?
 
Try lowering the vcore a touch. Iirc your chip is a CO stepping, the CO revision chips do run a bit hotter, and often required higher voltage for a given oc than the DO revision.
 
I gave everything a good vacuum and that helped bring the temps down a touch to the mid 70's. I pushed the bclk and had to reduce the ram mult to x8 and Windows BSOD during the OCCT test (about 10 seconds in). It appears most of the BSOD's I get are memory related. Should I try and keep ram mult to get 1600 and reduce the cpu mult?
 
whats ioh at 1.3v? I never had to touch that even at 4.2ghz

you mean cpu/vtt? if its failing on memory I would try with 1.32v cpu/vtt,

if you set the cpu voltage to normal and post what it uses in the bios here I can tell you what to enter into dvid,so cpu downclocks at idle

bsod codes are

101 not enough cpu v

124 not enough cpu/vtt

050 not enough cpu v

In CPU voltage list,you'll see it say normal,set to that save/exit then reboot into BIOS and look in the voltage list or system info to see what the CPU voltage is
 
You can try CPU v on normal,and set dvid to +0.05200v which equals 1.3v CPU voltage at load,enable all power saving eist c3/c6,disable c1e and set to balanced power profile in windows 7 or 8 power saving options
 
Ok,dvid allows CPU to idle,it will use less than 1v at idle and full speed/voltages at load

It will lower idle temps drastically,load temps won't be affected much you'd need to test

Without using dvid the CPU would run full speed/voltages all the time,instead of ramping up n down according to load
 
Yh I know your load temps are an issue,all you need to do now is lower the dvid,so maybe +0.050v,if stable try +0.04800v

Imo its better to use dvid rather than a fixed voltage as it let's the chip downclock and cooldown,to lower load temps you need to keep testing and lower dvid a little each time,a better cooler wouldn't hurt either
 
If I can get a water cooler that will allow me to be stable at 3.4 - 3.6 I'd be happy. My case doesn't allow anything larger than a single 120mm fan unless the radiator can be external (preferred)
 
I'm out of touch with the 1366 socket coolers,last ones I used was an akasa Nero cooler which wasn't bad,and a thermolab baram CPU cooler which was good but they don't make those anymore

Some decent paste might help too,mx4 for example
