Hi, I've bought a EVGA 9800GX2 recently and it seems like i have a low score.
My Rig is not that crappy though, i've seen that k|ngp|n managed to get 24k marks with little Overclock. I've got a max of 13300 marks on stock settings. Does anyone know what could be causing this ? is it my CPU that Bottlenecks?
LOL well first of all i don't play wow...anymore (ex-addict)
and even if that guy has a CPU @ 5.7 GHZ why would he get like 11k more points, i would at least expect a 15-16k pts ... no ?
The vidcard is being held back by the cpu, so obviously OCing cpu will bring out the potential of the vidcard. I must say, even at 3.6GHz on a quad will bottleneck the 9800GX2 in 3dmark06. That's probably why there's such a huge increase in points at 5.7GHz.
I can get my Q6600 to run at 3.6, but the vcore has to be ~1.5, and I've got to max the FSB and MCH voltages (+.3 for each on my P35-DSL3). I left the ram running at stock requirements. I don't run this setting because my temps were ~70C.
It's pretty hard to do 3.6ghz on air, but there's a few guys that have done it. I think most are using a lapped TRUE and cpu.
No man...No! You can't compare your scores to a professional OCer in the first place. Second, he is using uber high end DDR3 that costs over $500 and is OCd with new timings, a different and better mobo, an OCd GPU (738 check it), and an OCd CPU almost twice as fast as yours AND that is a 45nm. A little overclocked? Yeah, no, a lot overclocked IMO. You are trying to race your soccer mom mini van with a Ferrari.
If you want to compare 3Dmark06 scores look at Gx2 reviews where they aren't using a liquid nitrogen cooled setup. I know the first scores were on air but still you can't ignore the rest of the system because as you can see it drastically affects 3Dmark scores

There are lots of people zooming past 3.6ghz with lapped CPUs and the best air cooling available. I'm shooting for more latter, but I won't have time to pull my PC apart to do the work for another week or two.
You are using motherboard with 680i chipset. It will not go up to 3.6ghz no matter what you do due to FSB bottleneck. You need 780i or P35 for 3.6ghz, x38/48 for 3.8 and beyond.
3. You added +0.3 to MCH and +0.3 to the FSB Overvolt?
4. Do you have a fan on the NB?
Sorry for all the questions. Thanks.
1. Yeah 9x400
2. I did run prime, but for only ~20mins to see what the temps would be. Temps were ~70C, so backed off to 3.5ghz. Since then I've improved my cooling (I've got a Xigmatek S1283, I replaced the fan w/ a 110 CFM, and added more case fans), but I haven't really messed with 3.6 anymore because IMO I'm addding so much voltage and heat for so little gain. There's no point unless you're after a quick 3dMark06.
3. Yes
4. No. But the CPU fan sits right above it. I imagine there's pretty good airflow around my NB.
For everyday use, I run my CPU at 3.3ghz. I got to 3.5 stable (ran FFT for 8 hours), but I can run 3.3@1.35vcore with no MCH or FSB overvolt. 3.5ghz requires 1.45vcore and +.2 FSB and MCH overvolt. I don't think the small increase in speed (.2ghz) is worth it.
Depending on your chip, mobo, etc you should be able to get ~3.0ghz pretty easily on air. IMO, it's not worth to try for a whole lot more than that.
- You start needing "exotic cooling"
- You burn a lot more power and may need a high end PSU
- You get very little performance increase
