925 oc question

post #1 of 8
Thread Starter 
hi all, just built a super leet gaming rig for my friend:

Keyboard:G510 Logitech
mouse: Razer Naga
mouse mat:razer golitahus
speaker:Logitech 2.1
Monitor:21.5' acer HD
SSD:crucial M4 64Gb
HD:Seagate 500Gb 7200
MB:Asus M488TD-EVO
PSU:Corsair 650TX
GPU:Sapphire 6770
CPU: Phenom II x4 925
CPU cooler:Hyper 212+
Ram:2x2Gb G.SKILL Ripjaws ddr3 2000
case: AZZA toledo 301
lots of blue led fan in extra^^

so far its an awesome build, at stock it 2.8Ghz(14x200) @ stock volt(1.36) and my ram was at 1333, so i got max fsb of 295 keeping total clock of 2.8ghz, then raised multiplier one step at a time. BTW I WILL NOT PLAY WITH VOLTAGE, ALL MY VOLTAGE WILL STAY @ STOCK!! I got some problem really fast(around 295x11.5) so i lowered my fsb to 280, and got stable x13 multi(for a total clock of 3.65Ghz). i get very nice temp(46 degree under load and room temp is 30 degree, its all in the airflow^^), i am very happy with this oc, 3.6ghz is enough for me and with 280 fsb i got my ram to 1860 which is ok.

But i was wondering about something. i open speedfan and cpuz before launching prime95, and cpuz shows core voltage palying around 1.38 and the moment i start prime95 it stabilize the vcore at 1.356. Everything works great and stable, no prime95 crash, but i was wondering why does my vcore drops under load?

It might just be a misread. CPU-Z used to read my 945 at 1.175v constantly. The 925 has a locked multi, right? You might be surprised by how far it can OC; I used to be able to hit 4.2GHz with my Phenom II 945 (granted at ~1.5v). But if you don't want to raise the Vcore, I respect that.

Thats normal.
I'm not exactly sure about the science behind it, but at idle, there is basically 'power on tap' thats not being used and when under load, your pc uses more electricity causing the core voltage to drop. Something like that, I'm sure someone else will be able to explain it better..

AMD Overdrive or even RealTemp (depending on your motherboard) would work. I presume AMD Overdrive would be the most accurate. In my experience, CPU-Z is actually one of the least accurate diagnostics programs.

It's not dangerous in the slightest. It may have something to do with power saving features also. If your stable like stated above, I wouldn't worry about it at all and either call it a day, or try to overclock more
