post #11 of 16

My rig:
- Intel E6600 Core 2 Duo 2.4 GHz
- Corsair XMS2 PC5400 DDR2 667 MHz 2 GB (2 x 1 GB)
- Gigabyte P965 DS3 Mobo
- BFG 7800 GTX 256 MB Video Card

My Overclock:
- E6600 stable at 3.0 GHz
- vCORE at 1.250
- vDIMM at 1.9 with my RAM timings of 4-4-4-12
- Temps: Core #0 and Core #1 were idle at around 27 - 33 C
- Temps: Core #0 and Core #1 were full load (Orthos 7+ hours) at around 37 - 44 C


Okay, so that looks all fine and good right? BUT when I attempted to play a game (WoW) my frames were at about 8 FPS... They went from about 140 FPS stock to 8 overclocked...

I had my PCI-E frequency set at 100 MHz and when I put it up to 110 it seemed to go back to normal 140ish FPS. I was just wondering what else I could do, or what is going on? Shouldn't I be seeing a FPS increase? I also noticed when my PCI-E was at 110 that the game would be a tad more jerky.

Anyway hope to hear some responses. I am close to giving up and settling with stock.


Oh and totally off topic I have another problem. Is the temps from Speedfan "CPU" accurate? It runs at about 45 C with Orthos full load, but when I do anything with video it somewhat matches my video card temps. When I alt-tab out of WoW my "CPU" temp is at 66 C and my Core temps are around mid 30 C. Heck 3DMark06 had my "CPU" temp at 79 C. Which is funny because orthos will never get it past 45C.

Anyway I might post another topic with my 2nd problem.

Thanks

I've seen the same thing. Running an E4300 at 3.0GHz (334x9) which is a 67% overclock. I needed to bump my PCI-E to 112MHz (a quirk with the ASUS P5LD2 R2.0 LGA 775 Intel 945P motherboard) to stabilize the o/c.

My stock (1.8GHz) 3dMark06 score: 2300
My o/c (3GHz) 3dMark06 score: 2200


Power supply: COOLMAX CP-500T EPS12V 500W http://www.newegg.com/Product/Produc...82E16817159040

If the GPU and CPU are fighting for power, should I just boost voltage going to the GPU / FSB?

Thanks,
Paul

Yeah my 3DMark06 scores were about 150 points different with my +600 MHz increase. I had my PCI-E set to 110 MHz as well.

Is there a way to find out what your PCI-E is set to by default? My BIOS just says "Auto" when everything is at stock. (I lock it to 110 when I overclock though)

Could be from a different FSB stap, basically overclock more to get rid of it

Damn, I bought PC5400 RAM to hit a 1:1 ratio at 3.0 GHz but if the stap (I think that is what it is called) is the problem that sucks because now I will have to go above what my RAM is meant for. I know it can handle it, but I liked the thought of 333 x 9 at a 1:1 ratio.

Don't worry about the ratio. There is nothing to support the myth that 1:1 is faster/better/more efficient than 4:5 or any other split.

If you want to be fully informed, read this whole thread:
