Hey guys,

I just did my first OC on an i5 750 from 2.6GHz to 3.5GHz.

My RAM speeds (with XMP enabled) were 800MHz in CPU-Z.
After the overclock, the speeds are now showing 700MHz.
I have Corsair 1600MHz, 9-9-9-24, 1.65V RAM.

Here are some screenshots above.

My idle temps also look quite high, considering I have an arctic CPU cooler and thermal paste (well vented case).
They were around 25-30c idle at stock speeds.

Can someone please help, been stuck at this for a while and losing my mind!

Is my RAM speed operating at 1400MHz instead of 1600MHz a bad thing?
- The speed was actually around 1700MHz or so but I had to change the multiplier from 10 to 8 to lower it, is that fine?
And is there any way to get my temps down (voltage etc maybe?).
I seen some guys on random forums with great temps on the stock fans so I am not sure what is going wrong.
 
Temps look fine to me. If you change the BCLK to 200 you will get your ram running at 1600mhz again but you may need to increase the IMC voltage. If you keep the cpu multiplier at 20 giving you 4Ghz you will definately have to increase vcore, probably to around 1.35v or more giving you increased temps. Dropping the cpu multiplier to 18x will still give you 3.6Ghz and may not need another vcore bump.
 
Hey, thanks.

I noticed something wierd last night with regards to the temps.

The idle temps are around 50-55c, but when I play games (CS:GO, Farcry 3 etc) the temps stayed pretty much at around the same as the idle temps.

When I ran some stress tests they peaked as high as 80c though.

Any idea why the idle temps and gaming temps are the same? It leads me to believe that I could probably reduce the idle temps a lot more.

Right now I would just be happy with 3.5GHz, but I can't seem to get the RAM upto 1600HZ, and I don't really want to use a BCLK of 200 (175 right now) - Is there anything I can do?
 
My old 760 ran at 4.2Ghz (21x200) for a couple of years with no problems in a Asus P7P55D-E Pro. I specifically ran the bclk at 200mhz to get my ram at 1600mhz. It did not harm the system in any way. That is the only way you are going to get your ram back to 1600mhz if you don't have a divider that allows you to do it. I would rather have a high bclk with a slightly lower multiplier than a odd bclk with a higher multiplier.

I would try reseating that cooler as the idle temps are too high now unless it's a software bug reading the cores wrong. Does the cpu show up as having any load on the cores at idle? Stress tests are ok for testing stability but in real day to day use you will never get that high.
 
is power saving enabled? that will help with idle temps

what board are you using? you need to clock through cpu offset or dvid on gigabyte
 
Hi,

Thanks pasty I'll give that a shot.
My temps right now are actually 40-45c at 0-10% idle.

what board are you using? you need to clock through cpu offset or dvid on gigabyte

My board is a Gigabyte P55A-UD3R.
What exactly do you mean by clock through cpu offset or dvid?

Just out of curiousity, what would good idle temps be on my system for the overclock if the idle temps pre-oc were around 25-30c?
 
mid 30's to low 40's

set cpu voltage to normal,then maybe try with dvid at +0.0750v then see what load cpu v is under load while stressing

if too low add two or three clicks more dvid,or lower by using less dvid,be sure that the first two digits are 0 tho,so +0.0 so not to overvolt the cpu

enable all power saving eist,c3/c6 leave c1e disabled and select balanced power profile in windows power saving options

then cpu should use less than 1v at idle
