Just overclocked my CPU and GPU for the first time

[legion1capone]

Just overclocked my CPU to 4.3ghz and my MSI GTX580 Twin Frozr ii to 875mhz! Not bad for my first attempt. I can now play BF4 on ultra without any hiccups in game. Before I had to keep it on high. FYI I did not touch the core voltage on the CPU. I used Unigine Valley, MSI Kombustor, Passmark and Prime95.

If you left voltage on Auto the board did the fine tuning.

Yea make sure your watching your temps.

While the MB can adjust voltages depending on multiplier , if you raised LLC any the voltage will be on avg more than needed .
I bet you can run same 43x with voltage much lower, in the 1.18-1.20 range . now if you go up to 44x , 45x yes you need like 1.25+ on avg .
42x is sweet spot were you can run basically stock voltage still (1.10-1.14 range) and 43x needs just touch more most times .

You can probably lower the voltage on the CPU, if you left that setting to auto its likely using more voltage than it needs or should use. Try using negative offset, start with -.02v and see what happens. If its still stable try -.04 etc. Auto CPU Core Voltage is essentially running the chip close to its internal VID table voltage. With Negative offset, you are subtracting the amount of offset from the auto value. This will help keep it cooler.

The lower the voltage, the lower your temps. Raising clock speed will also increase temps, because you are increasing the amount of work.
So you should try for lower voltage, always try to find the minimal voltage for stability to keep the temperature as low as possible for a given clock speed. Under 80*C max is a good goal with Ivy.

This might be optimistic, all chips are different and 1.10v stock voltage is pretty good, most chips aren't that decent. I agree that he should try lower voltage though for sure.

agreed , i should of mentioned above is for good chips, everyone is unique , but I am still pretty sure he can lower voltage a decent amount for that multiplier . It all depends on his VID and what he set for LLC .
Agree , use small - offset to see where it goes

cpu and gpu wise every chip are unique indeed, for example my EVGA 580 Oc'ed a bit under my Zotac or my Matrix's

kinda the same setup as yours i7-920 @ 4.2ghz + Zotac @ 950/2350 (yep a 920 is on the level of a IB i5)

EVGA @ 935/2100 woops it's heaven not Valley (try it!!!) on a X4 760K @4.2


Matrix @ 903/2200 +i5-2400


Matrix SLI @ 900/2100 +Xeon E3-1275V2
