Differences between 3.4 ghz and 3.8 ghz at games

[haszaszyn]

This review at legionhardware has some crossfire scaling for a Phenom II X4 at different clock rates .

Thanks for that site, I couldn't find any good benchmarks on any sites from my country 😉 In free time I'm gonna test deeper my cpu after OC and maybe I'll stay on 3.8ghz. Thanks for help! 🙂

I didnt see any appreciable difference when I toggled my Q6600 between 2.4 and 3.0 GHz. Probably because a stutter is a stutter even if the time of the stutter is cut by 25%, it's still not enough to make a stutter disappear.

hmmm, when I'm doing OC only for cpu multiplier then it's everything ok, but when i increased cpu northbridge frequency from 2000 to 2200 mhz then in prime95 after few seconds I have fatal error on one core. Do you know what should i do in that situation?

If it's only one core failing, and you arent getting a BSOD, it may need a slight bump up in voltage. If your temps are ok

How stable is your voltage under load? Are you using any LLC settings?

 

[haszaszyn]

Under load my voltage was at 1.475 all the time, I don't use any llc settings, i think so :d

Try to find your stable CPU clock & voltage, then back those down and find your stable NB clock & voltage, then combine the two and see if you still have trouble.

3.4 pushes things on the stock cooling on my 965. You'll want to go with some aftermarket cooling. You may not notice 10% increase in performance. Here's what you need to do. Turn on a tool to measure framerate. Some games have them built in. Play for awhile and note your FPS or use a tool to measure it like FRAPS. Then set your graphics settings to low on any game that you think you're getting framerate limited and see if that improves your framerates. If yes, then you are CPU limited. This is an easy thing to measure. There is no need to rely on opinions.

Hubble, I believe you misspoke about GPU limitation vs CPU limitation.

If you turn down the graphical settings and your framerate increases, that means you are GPU limited. If you turn down the graphical settings and the framerate does not increase, then you are cpu limited.

Another way to tell what is limiting you is to use task manager to monitor CPU usage and something like MSI afterburner to monitor GPU usage. If one of them is 100% utilized and the other is a lot less, then the one being used 100% is limiting. I think that cpu and GPU should be fairly well matched, so you might see nearly full utilization on both, in which case you would need to upgrade both to see a major increase in performance.

Hello. I have one question to you, I have processor AMD Phenom II X4 965 BE and I would like to know from you is there much differences in fps in games between those two clock speeds 🙂

Rest of my PC's hardware:
Asus GeForce GTX660 Directcu II
MOBO Gigabyte MA770-us3
8GB DDR2 800mhz

No difference at all. maybe 1 or 2fps gain on avg. gl
