I just wanted to check if any of you folks with vastly superior overclocking experience might have experience with the hardware I use.
I'm using an EVGA 780i motherboard in conjunction with a q9450 processor. My current bios settings are for 3.4GHz on 1.25 volts. I have tinkered with going to 3.6, but I haven't found a p95/24 stable set up for that. I use corsair xms2 6400 5-5-5-18 ram, 2X2gb.
If anyone has a simlar set up and has gone beyond 3.4Ghz, I'd be curious to know what settings you used.
I'm not trying to set my rig on fire, I'm just curious to what the settings would need to be.
I also have a 9800gtx gpu. I'd like to, from anyone with the same card, what settings you get good results from. Now that the new beta drivers allow for the fan to be set properly, I'm wanting to find a decent overclock for the gpu that won't run the temps up to high.
I'm still pretty new to this board, and I've been really pleased and I appricate the helpfulness that you guys have offered so far, and I'm excited to hear the input on these settings.
780i chipset runs at 1333mhz fsb natively, and reliably oc to 1600mhz. 1600mhz fsb = 3.2ghz on Q9450 (8x multiplier). You've already exceeded reasonable expectations. Good job.
9800gtx should be good for up to 750mhz core. It shouldn't run into any artifacting or heat problems up to that speed. 9800gtx's performance in general is quite underwhelming though, not worthy of "9800" or "gtx" title. See benchmark: http://en.expreview.com/2008/04/03/geforce-9800gtx-revi...
So the mobo + X8 multiplier is pretty much going to keep me about where I'm at for max overclocking?
I would not have bought a 9800gtx to replace any 8800, but I was upgrading from a 6 series so it was a decent value. My plan was to buy a decent single card now, and wait for the next line of real upgrades to come out and upgrade then, maybe even "step up" if they come out soon enough.
I've read that review before, the comments are pretty funny. The line between truth and decent English really breaks down there.
I'm going to surrender the notion of getting 3.6 prime stable on this MB. Best I've gotten is about 30 minutes before I get an error or the comp just says no.
However, I am prime stable at 3.4, and now that my gpu fan isn't bugged, I've been testing it out a bit.
After some bumping I came up to 815/2038/1200.
I only ran 3dmark06 and rthbdribl at these settings, and I didn't see any artifacts in that. However I am kind of a noob, so if someone could suggest a good program for testing artifacts, I'd appreciate that. If it turns out that I'm a super noob about artifacts and testing gpu stability, you can disregard the rest of this post.
I'd like to know if there is a better program to use when checking gpu temps. I run rthbdribl at ~1920X1080 for ~10 minutes and see how hot it gets. Here's what I got for that OC, idle temps were 39-41, fan at 100%.
@3.4Ghz I got this
That's idle vcore. Under load it goes to 1.16v.
Comparing to other scores with one GPU and my processor, I'm pretty happy with this result(top of the 9800gtx pile at 3.4Ghz).
Just for grins... @3.6Ghz
FYI, that's less than 1000 points under they highest scoring 8800 ULTRA in the 3.4-3.6 processor range(per ORB).
Again, thank you guys for all of your helpful input.
I'm going to revert to stock clocks till I get some feedback on settings/stability testing, but it's been fun tooling around this evening.
