Unfortunately my E8400 isn't a lucky one...
If i get lower with v-core I get bsod when running orthos blend.
I might trying to go down with other voltages to see how the system react.
Stay tuned. :)

Read your cpu-z validation. Your getting 544 fsb outta 780i? Is this common with Wolfdale? Quads are getting 450 on these? I might get on of these boards. I lost my overclock on 650i and cant get it back. Cant get 3600 even at 1.42 without locking up, and cant run ram at 1000 if cpu overclocked at all.Quote:

I just not sure if about running my ram over 2.2volts.Quote:

I was watching a video that someone had posted here. And the video tells about overclocking the 780i. In the video the guy says that we need to set GTLVREF's to +0.5 in BIOS, or, we will receive instability? Is this true?

that's one of the reasons I replied to your post... You will see some gain surely in benchmarks and co but not very noticeable on day to day basis... I hardly notice the difference between 400mhz or 1066Mhz on the ram... if ya want to keep these rams keep them at 1000mhz 5-5-5-15 at normal volts... 1200mhz for fun and benches...Quote:

I will leave it that. there is no really gain for 1200mhz.
Thanks
Well I have 1100mhz running at 5-4-4-15 with 2.2volts, no errors. 1140mhz seems to be max for these sticks, more voltage does not help.
So really that is good enough. Sure would be nice to see dd3 price down below $200.00.
This ram will have to do until then.
my mate did this to his xfx780i.....
He noticed his raptors in raid were slower on the xfx780i than his intel chipset as with the 780i drivers you cant enable/disable the write catch so he put the 680 drivers on from there website so see what happens. The 680 drivers allow you to enable/disable the write catch which made his raptors a lot faster. He has had no problems with it yet, although i told him the 3rd pci-e probley wont work but he isn't putting a 3rd card in anyway. I might give i a go over the weekend as ive benched my raptors in raid and there also slower:shrug:
Thanks,
Chris.
Hi guys, I received my 780i EVGA today and today I found this
http://www.tigerdirect.com/applicati...=CP2-DUO-Q9300
is it worth it? does the 780i really works with yorkies without any problems or bugs? I currently have a C2D 6750 @3.6GHZ currently on my MARS, I dont know if that would be enough for my G92 GTS Sli please I need advice thanks
Hey I have an E8400 running on the 780i at 1800 FSB @ 4050. Best of luck!
hey starage nice mem latencies I ordered 2gb 8500 crucials as well
I'm the one who found that... you know... I set it to those settings and I'm pretty sure it helped me achieve more stability. I cant pass prime without those settings. I have no idea what those lanes are and what they do but it works for me and it isn't hurting anything.Quote:

I've had issues running four on a P35 board. I'm told an x38 works better than the P35. How is the 780i?
Looking for some info.
Have any of you guys noticed running 2.2V or higher vdimm for a while suddenly has your board being unstable?
I have seen a few people rma'ing memory only to find the new kits act as bad as the old ones, the end user then swaps or tests the ram in another board only to find the ram is fine.
So, if you are running high voltage how is your board fairing up?
I think mine just went bad.Quote:

I benched with the Gskill PC8000HZ (4-4-4-5 2T ) sticks Tony at 450FSB with 10X and 1200mhz 2.35volts 5-5-5-15 2T no issues with P03 bios on the eVGA... but a bench run only takes what 15 mins.. but I repeated them during 3 days to get some good scores... didn't do a thing here...Quote:

I think the memory is actually still good though, my other set of 1066 ballistix can't run 1066 anymore in this board either.... pretty sure the boards crapping out.
Are you sure it is the memory and not the memory controller? On my P35, I was told it had to be a memory problem. However, cranking the fsb down to 266, and setting the memory at spec (800 5-4-4-15 or 1066 5-5-5-15 depending on the sticks) it ran just fine. Although Memtest freezes after a couple of hours or so. Freezes, not reporting an errors.
I would try that first. With the QX9650 I would try 333 fsb, you could get most of the speed back my raising the multiplier to 12. However, if it is the memory controller, you probably need to RMA the board.
Cant get my system to boot now, comes up with 7F code
System was working fine, and was no longer OCed just running stock speeds, new ram arrived today so went to put that in... then i get long beep upon startup but no post!
Tried with old ram and new and system does long beep and fails to post!
Tried turning off PC, then resetting Cmos with jumpers
Also tried turning off system and taking battery out.. still no avail.. perhaps not long enough? :shrug:
Board is picky with FSB:DRAM ratio's, anyone else notice it? I cant do unlinked 1780 / 1000 .. 1780 / 1088 etc none of it works.. Will bench for a couple of minutes to an hour depending on what i try. Voltages dont help. So now im at 1780 / 800. 4-4-4-12 1.95v on the mem and low voltages on SPP / MCP (i have the modded SPP fan)
I have mine at 1800mhz with the memory unlinked at 800mhz. It give it a 9:8 ratio in CPU-Z. I think that you will have some luck with that. Try not to give it odd numbers maybe. Shoot for 1800mhz and 1000 in your case. The ratio should be 9:10... it might work better!
I've tested those settings before. Meh it doesnt really matter much to me. I have low voltages with a speedy system. Im fine with where im at. Until i get the itch to tweak again i'll leave it. Having to much fun gaming etc on this ubar system :cool:
i had a heck of a time finding stable combinations. 400, 450 and 475 seemed to be the only ones that worked for me. i can't get the board to post at 500. i ended up at 475*8, 1:1 linked and synced (i think that's what bios calls it). although oc'ing was more difficult than my 680i, it's doing a much better job. i was able to bench at 450*9 on the 780i, whereas the 680i wouldn't come close.Quote:

I wanted to go higher but was out of vcore. I feel if ya want to Bar-B-Q a chip i should be able too. I doubt evga will release a bios with any higher vcore.
I still run the chip at 4050 for 24/7 with the same vcore I had before them overkill voltage runs. maybe once i get my chiller up an running the results will be differant. 780i FTW
