E6300 bottleneck

hi, was just wondering, i have a pentium E6300, dual core Wolfdale @ 3.4Ghz overclocked from 2.8Ghz.....running on an asus p5q-pl mobo, 4gig mushkin 800Mhz DDr2, and an MSI 4870 1 gig. all this is usually run on my 42" plasma tv, but also runs on a 15" 1024x768 monitor......is my cpu bottle necking my gfx in any way? i have an asus p5k-premium board but been lazy to install in, would that make any difference (huge) in performance?

thanks alot

  1. Nope.

    A E6300 @ stock 2.8GHz was fine when paired with up to a 4890. Your OCed one should have no problems at all.

    Btw, you can take it much higher (4GHz-ish)...I have an E5300 myself (stock of 2.6GHz) and I took it to 3.6GHz with stock voltage.
  2. i also have a E6300 at stock speeds and a XFX 4890. i heard that my CPU is a huge bottleneck for gfx card. do you thing that if i overclock my CPU i will get a big performance boost?

    thanks
  3. and also will i have to buy an aftermarket cpu cooler??
  4. 3.6 is all i get out of it with stock cooling and stock voltage.....any voltage reccomendations for it? right now according to cpu-z its voltage is at 1.120V....

    and i only have a 500W cooler master lite ps, so is that enough for overclocking further?

    my 4870 is also overclocked, running at 850 core and 1050 memory.....is my ps going to struggle if i overclock my cpu into the 4Ghz mark?

    If your PSU is quality, 80+, it should be fine. I have an Antec 550 and an overclocked Q9550 as well as a similar overclock on a HD4870. Your Voltage is a little higher then mine (1.086) but I wouldn't think you have to worry unless you have 3-4 hard drives in the same machine.
  6. ok, i nly have 5 case fans all about 120mm, and 2 hdd's..

    Get an aftermarket cooler and increase the stock voltage. The "stock voltage range" is up to 1.36v...and it's generally considered safe if you keep it not too far above 1.4v

    I have an E5300 @ 2.6GHz ---> 3.6GHz with 1.32v
    Try increasing your voltage to 1.26 or 1.3 or so and set it to 4GHz

    Your CPU is not a huge bottleneck. You have a minor bottleneck, but it can easily be solved with an overclock. (look at my Tomshardware link in the 2nd post to compare E6300 + 4890 bottlenecks). Overclock several hundred mhz and you should be good to go. Th E6300 can reach 4GHz and over without much difficulties.
